2002-04-28 Kjartan Maraas <kmaraas@gnome.org>
* zvtterm.c vtx.h: Fix selection bug. From John Gotts
<jgotts@linuxsavvy.com>. Fixes #13485.
2002-03-18 Kjartan Maraas <kmaraas@gnome.org>
* Makefile.am: Up version number since we've added API the last
release. This should have been done before 1.4.1.4 :(
* vt.c (vt_setmode): fix a typo which causes dialog --infobox to
not leave its message displayed. patch from Richard
Braakman <dark@xs4all.nl>, fixes #75289
2002-02-16 Kjartan Maraas <kmaraas@gnome.org>
* vt.c (vt_reset): Use strlen() not sizeof() to find length of a string.
Thanks to the debian guys.
2002-03-05 Havoc Pennington <hp@redhat.com>
* zvtterm.c (request_paste): ask for the right targets in the
right order. Remove #ifdef hell.
(zvt_term_writemore): handle EINTR
(zvt_term_selection_received): use zvt_term_writechild not
vt_writechild so that we handle the case where the child can't
accept all the data right away. Solves the problem with
pastes getting truncated to 4K or so. (4K or so was the size
of the kernel write buffer or something, presumably.)
2002-01-22 Kjartan Maraas <kmaraas@gnome.org>
* vt.c, vt.h, zvtterm.c, zvtterm.h: Add support for dtterm escape
sequences. Patch from bugzilla. (Debian) Please test.
* zvtterm.c (vt_draw_text): Fix off by one error in underlining.
(Ximian)
2002-01-12 Kjartan Maraas <kmaraas@gnome.org>
* update.c, zvtterm.c: Remove unused stuff.
2002-01-10 Kjartan Maraas <kmaraas@gnome.org>
* *.1, Makefile.am: Add man pages.
2001-11-23 Gregory Leblanc <gleblanc@linuxweasel.com>

* zvtterm.h:
Miguel asked me to apply this patch. It's the rest of the changes
from RedHat to support multibyte locales, I believe. Things
applied without any conflicts, and I've tested that it compiles,
so I'm putting this into CVS. Enjoy, and flame me if it's broken
(but tell somebody else, since I can't fix it)
2001-11-11 Miguel de Icaza <miguel@ximian.com>
* gnome-pty-helper.c (init_term_with_defaults): Integrate patch
from Red Hat (set initial settings to ECHOK, Alan Cox posted a
description a few months ago about it).
2001-10-14 Xavier Bestel <xavier.bestel@free.fr>
* zvt/vt.c: Now correctly reports mouse wheel events
to applications (e.g. VIM).
2001-09-13 Havoc Pennington <hp@redhat.com>
* Makefile.am (libzvtincludedir): move to includedir/gnome-1.0
2001-09-18 jacob berkman <jacob@ximian.com>
* zvtterm.c (zvt_term_init): default to cursor not filled
(zvt_term_realize): don't start the blinking here. fixes gnome
#13120
2001-06-14 Miguel de Icaza <miguel@ximian.com>
* subshell-includes.h: From Dan McNichol: IBM compiler defines
_XOPEN_SOURCE, only define this if it is not defined before.
* zvtterm.h: Remove comma in last member of enum.
2001-04-18 Dan Winship <danw@ximian.com>
* gnome-pty-helper.c: Remove #include <malloc.h>
2001-03-05 Stanislav Brabec <utx@penguin.cz>
* zvtterm.h, zvtterm.c: New bit del_is_del, new function
zvt_term_set_del_is_del. New default behavior of Delete. Main
purpose of new default behavior is to be in sync with XFree86 and
allow "Emacs-friendly" mode (make difference between Ctrl-H,
Delete and BackSpace). Delete now defaults to Esc[3~ (VT220's
kdch1) and del_is_del forced DEL/^H.
* zvtterm.c: Changed codes for Home and End keys from X11R5 ones
(Esc[1~ and Esc[4~) to X11R6 key_home/end ones (EscOH and EscOF).
If keys don't work with readline apps, you probably need to fix
terminfo entry.
* zvtterm.c: "Metafy" characters with MOD1 or MOD4. Fast solution
of fact, that XTerm metafies characters with MOD1 on 102 keyboards
and with MOD4 with 105 keyboards.
* zvtterm.c: Generate code for Menu key.
* TODO: Note about modifier remapping.
2000-11-25 Not Zed <NotZed@HelixCode.com>
* vt.c
(vt_parse_vt): When we get a utf-8 start character, check that it
is in range (max of 4 chars for a valid utf-8 char), see standard,
section 3.8, D36. Fixes some crashes where a big shift char (like
0xff) could create an over-run c.
2000-10-23 Jacob "Ulysses" Berkman <jacob@helixcode.com>
* zvtterm.c (zvt_term_motion_notify): don't increment y by the
scrollheight here, since it wasn't done before the previous patch
This fixes selection when the window is scrolled back
2000-08-24 Not Zed <NotZed@HelixCode.com>
* update.c (vt_line_update): Dont clear the line modification
count here. Basically when we get an expose event, we shouldn't
clear the tag that says we have new data to render, for a line,
unless we are rendering the whole line. Otherwise because we
process scroll expose events recursively, we can end up losing
changes to the display. Fixes, well i dunno, probably a whole
bunch of bugs to do with rendering/scrolling etc.
(vt_update_rect): Set the modcount to 0 if we do render a whole
line.
(vt_update): Reset the modcount of all lines in the final pass of
processing.
* zvtterm.c: A bunch of patches from redhat:
- Fix for a problem with pointer grabbing in selection.
- Another for motion notify again in selection.
- Background rendering fix.
- Fix from Paul Warren <pdw@ex-parrot.com> to ignore double-clicks
of the middle mouse button (and expanded to include wheel buttons).
(zvt_term_button_press): A fix from Justin Mason <jm@jmason@org>
to make sure button presses take the border into account.
(zvt_term_button_release): And applied here.
(zvt_term_motion_notify): And here too.
2000-06-20 Kjartan Maraas <kmaraas@gnome.org>
* gnome-utmp.c (write_login_record): Fix some warnings.
Sat Jun 17 20:14:37 2000 George Lebl <jirka@5z.com>
* zvtterm.c (vt_cursor_state): don't draw the cursor outline when
in backscroll (using the same logic as in vt_draw_cursor)
Fri Jun 16 12:17:53 2000 George Lebl <jirka@5z.com>
* zvtterm.c (vt_cursor_state): Draw the no-focus cursor as an
unfilled rectangle. This makes figuring out which terminal is
focused much easier and is consistent with the xterm behaviour
2000-05-20 Jacob Berkman <jacob@helixcode.com>
* subshell.c (zvt_init_subshell): set SIGHUP to default, since
gnome-terminal is now ignoring it
2000-05-12 NotZed <NotZed@HelixCode.com>
* zvtterm.c (vt_scroll_area): Ok, so we do have to handle all
expose events before continuing. Must've been some sort of race
condition that didn't show up on my system before. Bug #10182
fixed.
2000-03-20 Jacob Berkman <jacob@helixcode.com>
* gnome-utmp.c (write_login_record): patch from Gerald Britton
<gbritton@mit.edu> for utmp handling
2000-03-06 Elliot Lee <sopwith@redhat.com>
* gnome-utmp.c: strncmp returns an int, not a pointer - act
accordingly.
2000-03-02 NotZed <NotZed@HelixCode.com>
* update.c (vt_update): When scroll-updating, dont update till the
end of the screen, unless we have a background pixmap. Fixes a
rendering glitch when multiple scrolled regions have occured
between updates.
2000-02-14 Timur Bakeyev <timur@gnu.org>
* gnome-utmp.c: Changed [sizeof()] to [sizeof()-1]. That prevents
overriding next field. Stupid me...
2000-02-14 Timur Bakeyev <timur@gnu.org>
* gnome-pty-helper.[ch], gnome-utmp.c, subshell.c, zvt-term.h,
zterm.c: Applied patches from Andrew J. Korty <ajk@waterspout.com>
that fixes/extends such parts:
* gnome-pty-helper didn't raise permissions after dropping them, so,
updates to the utmp/tty permissions didn't work... Thanks a lot!
* Add support for lastlog records, if possible.
Patches re-worked a bit to be more consistent. Also, some mine fixes
to the original code.
2000-01-29 NotZed <notzed@zedzone.helixcode.com>
* zvtterm.c (zvt_term_destroy): Free colours if they are set.
(zvt_term_init): Initialise queue_*, and use g_malloc0() for
private data.
Fixes for bug #5574, fixes from Petr Tesarik
<tesarik@petr.lupa.cz>, and Fabrice Bellet
<Fabrice.Bellet@creatis.insa-lyon.fr>
2000-01-22 NotZed <notzed@zedzone.helixcode.com>
* zvtterm.c/h (term_force_size): Back-port resize and colour-setting
fixes from HEAD version.
* vt.c (vt_reset): Send a properly formatted DA response, and
implement a DA2 response. DA2 should only be sent if this is a
vt220. Duh.
(vt_parse_vt): Added state 10 for \e[> ...
1999-12-21 Miguel de Icaza <miguel@helixcode.com>
* zvtterm.c (zvt_term_key_press): Pass the time request_paste
(fixes ICCCM compliancy bug, check bug tracking system).
(zvt_term_button_press): ditto
(zvt_term_selection_received): ditto.
(request_paste): Take time argument; Pass this to
gtk_selection_convert instead of GDK_CURRENT_TIME.
Fixes #4273
1999-12-06 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* Marked this point with zvt-merge-1, to indicate last merge with
HEAD.
* vt.c (vt_up/down/left/right): Use gotoxy to move the cursor.
1999-11-16 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zterm.c (main): Highlight url's using colour as well as
underline. Ick red on green!
* vtx.h (struct vt_match_block): Include 'saveline', a place to
store a copy of the line if we're highlighting using colour.
* update.c (copy_line): Convenience function, clones a vt line.
(vt_highlight): If the highlight includes colour, then save the
line temporarily.
(vt_unhighlight): New function, removes highlight. If the
highlight line was saved, then restore that, rather than just
inverting.
(vt_match_highlight): Call vt_match_unhighlight() when removing a
match highlight.
(vt_free_match_blocks): Free the b->saveline, if it is set (should
never happen ...).
(vt_getmatches): Initilaise saveline to 0.
* zvtterm.c (zvt_term_match_add): Dont strip off colour bits.
Updated doco.
1999-11-02 Miguel de Icaza <miguel@gnu.org>
* gnome-pty-helper.c (open_ptys): Use cfsetispeed and cfsetospeed
for setting the line speed instead.
1999-10-28 Miguel de Icaza <miguel@gnu.org>
* gnome-pty-helper.c (open_ptys): The defaults are now set to stty
sane.
1999-11-01 Dick Porter <dick@acm.org>
* gnome-pty-helper.c: Fix fcntl() error handling
1999-10-29 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* vt.c (vt_setmode): Oops, inverted the blank cursor logic.
1999-10-28 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_getmatches): Incase we get a dumb regex that
matches an empty string, we need to scan the whole line, character
by character. Slow slow.
* vt.h (VTMODE_BLANK_CURSOR): New flag bit for mode. Indicates a
blank cursor - do not poke this bit directly!
* update.c (vt_draw_cursor): Do not draw the cursor at all, if we
are in blank cursor mode. Blank cursor by issuing \E[?25h,
\E[?25l to turn it on again.
* vt.c (vt_setmode): Implement cursor blank control character.
1999-10-20 Miguel de Icaza <miguel@gnu.org>
* gnome-pty-helper.c (open_ptys): VDISCARD character is control-o,
not control-u, which is already used for VKILL. Fixes problem
posted to gnome-libs.
1999-10-19 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_lf): Make sure we dont linefeed off the end of the
screen, bug #2885 (and probably most other segfaults). This may
cause problems elsewhere, but probably not.
1999-09-28 Elliot Lee <sopwith@redhat.com>
* zvtterm.c (zvt_term_key_press): Catch GDK_Tab _and_ GDK_ISO_Left_Tab
and use them appropriately. I don't think GDK_Tab really needed to be caught,
but oh well.
Also make builds with d(x) = x work.
1999-09-29 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (zvt_term_button_release): Ahh no, we dont want to do
the extend selection thing if the button was pressed, tahts why
this damn moved flag is here in the first place ...
(zvt_term_button_press): We want to indicate a 'moved' mouse
whenever we get a right click. Raph was right!
1999-09-28 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* vt.c (vt_setmode): Ahh .. if we switch from alt screen using
1047, we must clear the screen. How obvious.
1999-09-26 Martin Baulig <martin@home-of-linux.org>
* update.c (vt_match_clear): You must use g_free() to free a
g_malloc()ed piece of memory, not libc's free(); this segv's
when using malloc checking in glib.
1999-09-23 Michael Zucchi <mzucchi@denr.sa.gov.au>
* update.c (vt_getmatches): Keep track of the position of the
current match for multiple match scans on the same line.
* gnome-pty-helper.c (open_ptys): Another attempt ... this time
conditionally check every bloody flag before we try and use it.
1999-09-22 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* gnome-pty-helper.c: Make the use of ECHOKE/ECHOCTL conditional.
More portability fixes (this time its broken-irix bug #2321).
1999-09-19 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* vt.c (vt_set_text): Return VTTITLE_XPROPERTY as a title type
when the mode number is 3.
* vt.h (VTTITLE_XPROPERTY): New title type, requests a setting of
an X property.
* vt.c (vt_setmode): #@$@#$@#$# when the send mouse was being set,
the mask was beign applied inverted, and blowing away all the
other mode bits.
1999-09-19 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c: Removed the zvt_term_match_clicked() prototype,
function no longer exists.
* gnome-pty-helper.c (open_ptys): If the system defines the
default tty settings (TTYDEF_xFLAG), then use them, otherwise
create our own (hopefully portable?) versions.
1999-09-19 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_button_release): Make sure we update the
selection for a right click, even if the mouse hasn't moved.
1999-09-14 Michael Zucchi <mzucchi@denr.sa.gov.au>
* gnome-pty-helper.c (open_ptys): init the termio's structure to
0's (unknown fields?). Added some portability fixes for Solaris
at least (maybe this isn't as portable as it was supposed to be?)
(main): Fixed a warning with the uid type.
1999-09-14 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* gnome-pty-helper.c (open_ptys): Added patch from Alan Cox
<alan@lxorguk.ukuu.org.uk> to set termios to a known state,
instead of taking the terminal defaults.
* vt.c (vt_lf): Fixed line-feed implementation, for when the
scroll-range has been set. It was quite broken.
1999-09-14 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_setmode): Properly handle 1047 (==47) and 1048
(save/restore cursor position).
1999-09-12 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zterm.c (button_press_event): Changed to perform the lookup
manually, instead of relying on the signal - pity, the code was
cleaner before, but this isn't too much of a price to pay for bin
compat.
* update.c (vt_match_clear): Changed my totally stupid use of the
double-linked list (treating it as a single-linked list), to a
more sane and accurate version.
* zvtterm.c (zvt_term_class_init): Remove the match_clicked
signal.
(zvt_term_class_init): Ditto.
(zvt_term_button_press): No longer check/emit a match_clicked
signal.
(zvt_term_match_clicked): Removed dummy callback fn.
1999-09-12 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (zvt_term_match_check): New function, api call to get
the match string, when the application already gets the mouse
button events (hmph).
1999-09-11 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* Merge of ZVT_MATCH into HEAD.
1999-09-10 Michael Zucchi <mzucchi@denr.sa.gov.au>
* Makefile.am (EXTRA_DIST): Include the gnome-pty-helper sources
here, since we build it manually. Yuck. Blame Solaris' ld.
* vt.h (VTMODE_SEND_MOUSE): Put this flag back in. Make the other
mouse flags use this bit always, when they are active. Bit of an
annoying hack for backward compatability.
1999-09-09 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_report_button): Propertly report the 2 different mouse
modes. Only button presses, no qualifiers (X10 mode), and button
press/release + qualifiers (X11 mode?). Fixes bug #1888.
* zvtterm.c (zvt_term_button_press): Indicates direction of button
press to vt_report_button().
(zvt_term_button_release): Indicates direction of button press to
vt_report_button(). Also now passes the button number.
* Makefile.am (gnome-pty-helper): Added manual build target for
gnome-pty-helper. Because of some broken linkers we need to limit
what gets put on the link line (see bug #1246/#1576).
1999-09-11 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_get_capabilities): Added the new capability,
and updated the documentation to match.
* zvtterm.h (ZVT_TERM_MATCH_SUPPORT): New capability to indicate
the match functions exist/work.
* update.c (vt_match_clear): Free and match blocks (some of which
may point to this match type).
* zvtterm.c: Added missing gtk/gtkselection.h include.
* update.c (vt_update): Force highlighted matches to be cleared.
(vt_free_match_blocks): Ditto, after this the pointers are no
longer valid.
* zterm.c (main): Fixed invocations of zvt_term_match_add().
* zvtterm.c (zvt_term_feed): Turn off any match before reading any
data.
(zvt_term_readdata): Same.
(zvt_term_motion_notify): If we move the mouse over a match,
change the pointer to a hand, and highlight the match
appropriately.
(zvt_term_match_add): Added new parameter to specify the type of
highlighting to use - taken from vt attributes currently.
(zvt_term_set_pointer): New internal funtion to set the mouse
pointer and the reference to what it is currently, but only if it
has changed.
* update.c (vt_getmatches): Have each match include a number of
match blocks, rather than each match block indicating its parent
match.
(vt_free_match_blocks): Fixed for above change.
(vt_match_highlight): Highlight toggle, or clear a highlight match.
(vt_highlight): Implement toggling the highlight. Currently
it has to be somehting reversible, e.g. toggle bold/underline/etc,
or invert colours.
* zvtterm.c (zvt_term_show_pointer): Changed to check if we are
currently the dot cursor.
(zvt_term_unrealize): Free the zp->cursor_hand.
(zvt_term_realize): Allocate a zp->cursor_hand.
1999-09-07 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_motion_notify): Check for matches if we
haven't before, and the screen has changed.
* zvtterm.h (struct _ZvtTermClass): Added the new match_clicked
signal.
* zvtterm.c (zvt_term_button_press): Emit a match_clicked signal
when we get a right mouse button event over a match string. Hmm,
I can't see how we can do this for the other buttons without
interfering with normal operation :(
* update.c (vt_match_check): Check for a match given screen char
coordinates.
* zvtterm.c (zvt_term_match_clear): User function - to clear one
or all of the match strings.
(zvt_term_match_add): User function - adds a new match string.
(zvt_term_match_clicked): Dummy signal handler for the (new)
match_clicked signal.
(zvt_term_class_init): Add the new match_clicked signal.
* vtx.h: Added new 'magic match' data structures.
* update.c (vt_free_magic_blocks): New function - free's the list
of matched blocks (if there are any) and indicates that no match
attempt has been tried on the current display.
(vt_getmatches): New function - scans the _currently displayed_
screen for matches against the match regular expressiones. If any
are found they are stored as 'match blocks' which map to
rectangles on the screen.
(vtx_new): Initialise the new match functions.
(vtx_destroy): Free new match resources.
(vt_match_clear): Remove one or all the match regular expressions.
1999-09-05 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_line_update): Removed a dead comment.
1999-08-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.h (struct _zvtprivate): Added new parameters for
asynchronous writing/pasting of lots of text.
(zvt_term_writechild): New public function. Shouldn't be used by
pre 1.2 (1.0.50?) code.
* zvtterm.c (zvt_term_selection_received): Now calls
zvt_term_writechild() to write data to the child.
(zvt_term_writechild): New function - writes any amount of data to
the child sub-process through the child pipe, asynchronously if
required. Can be called mutiple times before writes are complete.
(zvt_term_writemore): New io write callback. Used to deal out
blocks of data overflowed from zvt_term_writechild() until its run
out. These changes fix bug #1899 & #1539.
(zvt_term_init): Initialise zp->paste_id & paste pointer.
(zvt_term_destroy): Free any resources from zp->paste_id or paste
pointer.
1999-08-16 Michael Zucchi <mzucchi@denr.sa.gov.au>
* update.c (vt_line_update): When checking for common blocks of
unchanged characters following changed characters, make sure the
current attr is taken into account.
1999-08-02 Elliot Lee <sopwith@redhat.com>
* subshell.c, gnome-pty-helper.c: Actually the problem was
that zvt was depending on receiving certain signals, but
zvt didn't do sigprocmask() to unblock signals that had been
blocked by the panel.
1999-08-02 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (zvt_shutdown_subshell): Fix the problem Elliot is
experimenting. Basically the code now allowed for two different
paths: one was the process natural death, and the other was an
explicit kill from the parent.
I think that the explicit kill is not required as closing all the
file descriptors should provide EOFs in good quantity to the child
process. *Unless* There is a file descriptor leak. If there is
an FD leak we should plug that instead of doing a kill SIGHUP the
child process.
I have kept this patch semantically correct with the previous
version on CVS but implemented correctly. But we should really
investigate this rather than putting a kill signal here.
So basically, we now keep track of whether the process has died or
not, and if so, the exit status of the process (to return this
value from the zvt_shutdown_subshell routine.
* gnome-utmp.c (write_login_record): Remove warning about unused
vaiable.
1999-07-28 Michael Zucchi <mzucchi@denr.sa.gov.au>
* update.c (vt_select_block): NUL terminate selection. Bug #1631.
1999-07-26 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_size_allocate): When resizing, turn off the
selection. Can cause inconsistencies in state. Fixes bug #1744.
1999-07-19 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_fix_selection): Some fixes from Matthijs Melchior
<mmelchio@xs4all.nl> for word selection.
1999-07-02 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (request_paste): Fix an out-by-1 array bounds check.
1999-06-26 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_line_update): When reverse video set, then force
background render always. Fixes a really nasty bug where lots of
text starts to vanish.
(vt_fix_selection): Another minor select-by-word fix.
* vt.c (vt_tab): When storing tab, dont over-write blank
attributes.
1999-06-23 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_in_wordclass): Make sure we ignore attributes before
doing character type tests.
1999-06-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (vt_draw_text): When we render bold, dont offset y as
well as x (well you can, but its kinda hard to read :)
1999-06-20 Michael Zucchi <mzucchi@denr.sa.gov.au>
* subshell-includes.h: Under Solaris at least, defining
_XOPEN_SOURCE means that the winsize stuff is NOT defined. I've
added a __EXTENSIONS__ define so it does get defined. Either that
or _XOPEN_SOURCE must be undefined. Hopefully this is portable to
other unices ...
This fixes bug #1435.
1999-06-19 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.h: Removed unecessary include of X11.h and Xlib.h.
* vt.h: Merged ZVT_UTF to head. Yay UTF8 font support. Roll on
new bugs I guess.
1999-06-18 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_key_press): Support function keys right upto
GDK_F20.
1999-06-17 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.h (struct _zvtprivate): New field transpix to store the
transparency pixmap pointer.
* zvtterm.c (zvt_term_draw): When we are asked to draw, make sure
the background fill colour is still right (themes can change them!
the cads!)
(zvt_term_draw): Go back to drawing clearing the whole area before
rendering, if we are using a pixmap (otherwise a bit of border can
be left).
(zvt_term_draw): Well if we are going to draw the background, make
sure we dont draw it when we draw the text too (set fill=17).
(free_transpix): New function, free the foreign pixmap wrapper for
the transparency pixmap.
(zvt_term_destroy): Free the transparency pixmap wrapper if it
exists.
(zvt_term_init): Set the tranparenxy pixmap to null.
(load_background): Fixed up a rather embarassing oops, freeing a
pointer we're using 3 lines above. The tranparency pixmap is
stored separately to the background pixmap, so we can free it and
track it properly, since we cannot unref it. I dont know how this
didn't crash more often!
* zvtterm.h: Removed the zvt_term_get/set_adjusetment() ifdef'd
out functions, so they dont confuse developers.
1999-06-14 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_expand_line): Range check start value.
(vt_fix_selection): Range check x values, at least above 0. For
bug #966.
(vt_update): When checking to see if we update the line, always
update if the scrollbar moved. vt_line_update() will optimise
rendering anyway.
(vt_fix_selection): Cleaner implementation of select-by-word. No
longer flickers/funny over selecting tabbed text.
* zterm.c (set_hints): Renamed size_allocate to set_hints.
Changed to use gtk_window_set_geometry_hints() instead of the X
call.
(main): Change the size_allocate signal to a realize signal, to
set the window hints once the window is realized.
* zvtterm.c (zvt_term_size_request): Removed bogus 'magic numbers'
from some of the size values.
(zvt_term_size_allocate): Removed a couple more magic numbers from
the size stuff, since it actually seems to work now.
1999-06-10 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* gnome-pty-helper.c (open_ptys): Use fchown()/fchmod() to set the
slave pty's ownership/permissions after openpty() returns. IMHO
this is fixing a non-existant bug, but who am I to argue?
(): Also include sys/stat.h, for S_* defines.
(open_ptys): Rewrote the last change to be a bit simpler!
1999-06-02 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_draw): Use a forced fill to draw the
background, rather than a big rectangle. Makes it smoother.
* update.c (vt_scroll_update): When we request an update, use
bl->width (the actual window width), not l->width (the stored line
width, which may not match).
(vt_update): Same.
(vt_draw_selection_part): Same again!
* zvtterm.c (vt_scroll_area): Added back some old code from about
version 1.10, that forces all expose events to be processed before
scrolling exits. If we are rendering scrolled pixmaps, things get
kinda bogged down and events get processed out of order.
(create_shaded_pixmap): When creating a pixmap for a partially
off-screen window, also treat that as a "tile".
* Merged ZVT_PXIMAP branch back to head!
1999-06-02 Michael Zucchi <zucchi@zedzone.mmc.com.au >
* zvtterm.c (zvt_term_init): Set _zvtprivate data before calling
any functions.
(zvt_term_set_fonts_internal): Create the bold-save pixmap of the
right size, if we need it (rendering bold).
(vt_draw_text): When drawing a bold text, grab 1 pixel of data
past the end of the text, draw it, embolden it, then draw the
pixmap back again. What a mess, but required for some TINY fonts
which use up all of thier size.
(zvt_term_destroy): Free the bold_save pixmap if it was setup.
(zvt_term_init): Initialise bold_save pointer to null.
* zvtterm.h (struct _zvtprivate): Add bold_save - a pixmap used to
save possibly overwritten screen when algorithmically generating
bold.
* update.c (vt_draw_selection_part): Make sure the back line
matches the draw line. Broke badly on selecting in scrollback.
1999-06-02 Michael Zucchi <mzucchi@denr.sa.gov.au>
* update.c (vt_line_update): Added background line to use for
updates. Fixed all callers. Saves a lot of calls to
vt_list_index() for each line rendered (maybe tops 2-3% difference).
* zvtterm.c (zvt_term_draw): Pass in background colour just
cleared to update_rect, so we dont render it twice.
(zvt_term_expose): Ditto.
* update.c (vt_line_update): Almost completely rewritten.
Simpler, and more obvious, and faster too!
(vt_update_rect): Added a fill argument, the fill colour that the
rectangle is set to.
(vt_draw_selection_part): Dont force update, cleaner selection
visual.
(vt_update): Only force background update if we are on a scrolled pixmap.
1999-06-01 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_set_color_scheme): Removed reference to
term_window.
(zvt_term_realize): Same.
(vt_draw_text): Dont draw a background box explicity, use
XDrawImageString() when we can get away with it. Maybe this saves
X traffic?
* vt.c (vt_resize_lines): Fixed up the indenting again.
(vt_resize): More indenting fixes.
* vtx.h (struct _vtx): Added scroll_type to the _vtx structure.
Indicates how the display might be scrolled, always (no
background) sometimes (scrolling background), or never (static
background). Added to end of structure, still bin compatible.
* zvtterm.c (zvt_term_realize): No longer setup a separate
terminal window.
(zvt_term_unrealize): Removed references to term_window.
(zvt_term_map): Ditto.
(zvt_term_unmap): Ditto.
(zvt_term_focus_in): Ditto.
(zvt_term_draw): Ditto. Also use back_gc as the clearing
mechanism.
(zvt_term_expose): Ditto. Also use fill to back_gc as the
clearning mechanism for pixmap backgrounds.
(zvt_term_show_pointer): Ditto.
(zvt_term_hide_pointer): Ditto.
(zvt_term_button_press): Ditto.
(zvt_term_button_release): Ditto.
(vt_draw_text): Ditto, plus a whole bunch of other messy changes!
Render pixmaps differently, and use XDrawImageString() when we can
for less X traffic. Offset rendering by klass->width/height,etc.
(vt_scroll_area): Ditto. Account for scrolling pixmap offsets
here.
(load_background): Ditto. General code cleanup. Renamed from
draw_back_pixmap.
* zvtterm.h: New options, ZVT_TERM_PIXMAPSCROLL_SUPPORT and
ZVT_TERM_TRANSPARENCY_SUPPORT, indicating that the terminal can do
transparency/scrolling pixmap. Transparency support is calculated
at run time. These should be checked with a #ifdef for 1.0.x
code.
New flag options to set_background.
* update.c (vt_scroll_update): Significant changes. The update
algorithm now knows about scrolled/static backgrounds. It uses
this to try and optimise screen updates.
(vt_update): A whole bunch of changes to accomodate the changes to
the scroll_update.
(vt_line_update): If we are in a scrolled-background mode, never
let the background text match, since the background !=
background. This should be dependent on if we are updating a
previously scrolled section or not? Room for minor speedup.
(vt_fix_selection): Removed some old dead code.
1999-05-31 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zterm.c (main): Repaired the fucked-up indenting.
* vt.c (vt_erase_chars): Only erase 'n' characters, rather than
from here+n to end of line. I think i got that really wrong last
time.
1999-05-29 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_tab): Set attributes for tab's too.
1999-05-24 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-login-support.c: Do not use ifdef (HAVE_STROPTS) but ifdef
HAVE_STROPTS. Thanks for Brandon for pointing this out.
1999-05-24 David KAELBLING <drk@sgi.com>
* vt.c (vt_func): Do not use un-initialized variable.
* gnome-login-support.c (pty_open_slave): Remove compilation
warning. Use ifdef XXX, not ifdef (XXX)
* subshell.c (zvt_shutdown_subshell): Assign NULL to vt->pty_tag,
do not compare it (it was a no-op).
1999-05-24 Raja R Harinath <harinath@cs.umn.edu>
* Makefile.am (install-exec-local): Uses separate `chown root' and
`chgrp root' rather than `chown root.root'.
1999-05-18 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_insert_lines): range check upper limit.
(vt_delete_lines): Ditto.
(vt_scroll_down): Ditto.
(vt_scroll_up): Ditto.
(vt_scrollback_add): Fixed more indenting.
(vt_parse_vt): Force all arguments to be unsigned values (assumes
2's complement storage).
* zvtterm.c (zvt_term_scroll): More indenting repair.
(zvt_term_set_font_name): Ditto (etc for everything else i spot).
Please use K&R style indenting if you make changes!
* TODO: Updated a bit.
* zvtterm.c (vt_draw_text): If a font is a 2-byte font, first
expand it to an XChar2b array. This will need to be changed so
it accepts 16 bit characters by default (but is a bigger task!).
Setting a -iso10464- (unicode) font should now at least render ok.
(zvt_term_readdata): Repair the Jay-ded indenting.
(zvt_term_readmsg): Ditto.
(zvt_term_set_background): Ditto.
(vt_draw_text): Ditto.
(vt_scroll_area): Ditto.
* zvtterm.h (struct _zvtprivate): Added text16/text16len to
zvtprivate - buffer for expanding 2-byte fonts.
1999-05-15 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* update.c (vt_line_update): Because some mental fonts use every
pixel position we need to clear the next character pos after a
bold font. Just render this last blank character always to make
sure.
(vt_draw_selection): Dont draw anything if the selected area
amounts to nothing, and it hasn't moved.
1999-05-10 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.c (zvt_term_destroy): Patch to clean up the timeout
handler if it is still running, from Timo Sirainen
<cras@fun157.kivikko.hoas.fi>.
1999-05-07 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.c (zvt_term_button_press): Use a better extend-select
end-choosing method. i.e. same as xterm. If you click before the
middle of the selection, it changes the start, otherwise it
changes the end.
* update.c (vt_fix_selection): If selecting the first word of a
line, 'by word', and it was 1 space from the left border, it would
select that space too - no longer!.
* zvtterm.c (zvt_term_button_press): Remove the input handler for
input_id when selecting text - i.e. block during selection.
(zvt_term_button_release): re-enable input if it was removed, and
the childfd exists.
(zvt_term_button_release): Only allow dropping of button-release
events if we're not selecting something (otherwise, select-drag,
hold ctrl, and release - it doesn't!).
Mon May 03 20:14:49 1999 George Lebl <jirka@5z.com>
* zvtterm.c: change the way we draw the background for transparent
images so that it works with tiled images (we assume every
background is tiled which is not always the case, this can
probably be fixed if anyone feels the need to do that, this
should work good enough for most people:)
Mon May 03 20:04:10 1999 George Lebl <jirka@5z.com>
* zvtterm.c: removed an #if 0 from the _draw method as it is
obviously there by mistake (if not then the code would need
to be fixed for background pixmap/transparency stuff).
Also fixed the code that clears the area to draw text on, now
it properly draws pixmaps, while preserving the speed improvements
made by michael for non-background terminals
1999-05-03 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* update.c (vt_expand_line): Fixed selection of single characters
at the start of an otherwise empty line (bug#1168).
1999-04-24 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_newline): Make sure a new-line is initialised with an
invalid line number.
(vt_scrollback_add): Set the new line's line no to -1.
(vt_resize): Set the line no's of lines that are no longer there
to -1.
* zterm.c (size_allocate): Make sure we add the PADDING width to
the size allocation of the terminal window when setting the window
base width hint. Hey it sizes right now! Now just to fix
gnome-terminal ...
(main): Add \n to the end of usage info.
* zvtterm.c (vt_draw_text): Changed conditions under which the
background is 'reset'. Should speed up refresh under expose
(since the screen is already cleared to the background colour).
(zvt_term_key_press): Implementation of application keypad
keycodes, from Kenn Humborg <kenn@avalon.wombat.ie>.
(zvt_term_button_press): Clear the rendered selection upon a
single-click.
(zvt_term_size_allocate): Dont size the terminal if it hasn't
changed. Also, why set size_pending? We just sized!
(zvt_term_size_allocate): Make sure we remove the PADDING area off
the size after we've sized it.
1999-04-15 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_scroll_up): Make sure vt->this_line is correct still
after the scroll!
(vt_scroll_down): And the same here.
1999-04-13 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.c (vt_draw_text): When drawing underline, dont go beyond
our char boundaries. I think this fixes the dot problems. Thanks
to Jesus Bravo Alvarez for this one.
(zvt_term_set_fonts): No need to check that 'font' is NULL. Its
not allowed to be by the api, and the g_return* assertion prevents
it from being called.
1999-04-10 Michael Fulbright <msf@majestic.labs.redhat.com>
* zvtterm.c (zvt_term_size_allocate): set term->grid_[height/width]
based on new geometry - seems to fix problem of terminal resizing
back to old size when you hide/show menubar.
1999-04-09 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty-helper.c (open_ptys): First set the GID, and then the
UID, since once the UID changes, you *might* not be able to change
the GID.
Thanks again to Morten for keeping such a good eye on our changes
and code.
1999-04-08 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty-helper.c (init_msg_pass): Return a value.
1999-04-06 Nuno Ferreira <nmrf@rnl.ist.utl.pt>
* update.c (vt_expand_line): declare c as unsigned so comparisions
work. Should't zvt be using unsigned char all over the place to
prevent things like this? By the way, this fixes bug #144.
1999-04-06 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
* zvtterm.c (zvt_term_set_fonts): only gdk_font_ref() fonts if
they are non-null in order to prevent some segfaults.
1999-04-04 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.h: Changed capability bits to #define's so they can more
easily be checked in new coder.
* zvtterm.c (zvt_term_get_capabilities): Set
ZVT_TERM_EMBOLDEN_SUPPORT for this version of the terminal.
* zvtterm.h (enum): ZVT_TERM_EMBOLDEN_SUPPORT - can call set fonts with a
NULL bold font to auto-generate bold effect.
1999-04-03 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_fix_selection): Make sure we only increment 'ex' if
it equals 'sx' on the same line, otherwise 'ex' can creep.
* Merged in ZVT_XTERMNEW branch again, to pick up Miguel's
stropts.h changes.
1999-04-01 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-login-support.c (pty_open_slave): Use the strams ioctls
only if the system has <stropts.h> header files.
1999-04-02 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zvtterm.c (zvt_term_set_fonts_internal): Query the XFontStruct
for the real font width, rather than picking 'width("M")' - might
fix the bold artifacts problem.
(zvt_term_set_fonts_internal): If no bold font is supplied, leave
it NULL.
(zvt_term_set_fonts): Allow a bold font to be null.
(vt_draw_text): If there is no bold font set, then use
over-striking to acheive the same result.
* subshell.h (zvt_shutdown_subshell, zvt_close_msgfd): Fixed
header entries/removed for changes.
* vt.c (vt_closepty): Just calls zvt_shutdown_subshell() and
returns the child exit status.
* subshell.c (zvt_shutdown_subshell): Moved all the shutdown
functionality here, includeing parts of vt_closepty(), and
zvt_close_msgfd().
(zvt_close_msgfd): Removed, no longer needed.
* vt.c (vt_closepty): Do an explicit waitpid() on the child process.
(vt_closepty): Dont set childfd==-1 before we see if it == keyfd.
1999-03-30 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* vt.c (vt_keypadon): Set VTMODE_APP_KEYPAD in vt->mode.
(vt_keypadoff): Clear " .
(vt_scroll): Only set scroll region on state 2.
* vt.h (VTMODE_APP_KEYPAD): New flag to signal application keypad
on. Doesn't do anything yet.
* vt.c (vt_gotoabsy): \E[nd -> goto n-1 y position absolute.
(vt_gotoabsx): \E[nG -> goto n-1 x position absolute.
(vt_erase_char): Callback function - erase characters.
(vt_erase_chars): Implement erase n characters.
1999-03-30 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_mode): Reset terminal attributes on '\E[27m'.
(vt_parse_vt): Add new state 8 for '\E[!x' sequence. Added
'\E[!p' terminal reset.
(vt_deccharmode): Add dumy callback for dec character mode stuff
(wide/tall chars, etc). '\E#n' sequences.
(vt_jumps[]): Added '\E[nT' pan up.
(vt_parse_vt): Added state 9, '\E[n'X' sequence.
* vt.h: Added integer argument array. Its a union with the text
argument space. The old redundant text argument variables are
still present, appended with _dummy - to be removed next major
release.
* vt.c (vt_scroll_reverse): New function, implements reverse
scroll sequence '\E[n^'. For ISO-6429 (ECMA-48) standard.
(vt_scroll_left): Scroll window left.
(vt_scroll_right): Scroll window right.
(vt_scroll_forward): Forward scroll - '\E[nS'.
(vt_up): Implements scroll window right '\En A' for state==7.
(vt_insert_char): Implements scroll window left '\E[n @' for state==7.
* update.c (vt_line_update): Implemented VTATTR_CONCEALED -
concealed text.
* zterm.c (main): Default size = 24 lines.
* vt.c (vt_init): No longer setup vt->args pointers.
(vt_insert_char): Changed to binary args in arg.num.intargs[]
(vt_delete_char): Ditto.
(vt_insert_line): Ditto.
(vt_delete_line): Ditto, and check state in switch.
(vt_cleareos): Ditto.
(vt_clear_lineportion): Ditto.
(vt_goto): Ditto.
(vt_modeh): Ditto. Also handle mulitple arguments.
(vt_model): Ditto. Also handle multiple arguments.
(vt_modek): Ditto.
(vt_mode): Ditto.
(vt_gx_set): Ditto.
(vt_dsr): Ditto.
(vt_scroll): Ditto. Also check that scrolltop<scrollbottom.
(vt_func): Ditto!
(vt_set_text): Changed to use string arguments union.
(vt_parse_vt): A number of changes. Added extra state '6', to
handle \E[?nnn;nn;nY sequence. All numerical arguments are now
decoded as they are encountered. Should be faster, and allows
more arguments to functions (upto 20). All control codes no
longer reset vt->argcnt. '\E]...' uses the arg.txt.args_mem area
to store its strings. '\EOx' sets intargs[0]=0 before calling
callbacks.
1999-03-28 Luca Lizzeri <ll@niche.it>
* gnome-pty.c (write_login_record): Fixed a typo with extra ")".
1999-03-28 Timur Bakeyev <mc@bat.ru>
* gnome-pty.c (update_utmp): New function, which accumulates OS
specific utmp-handling routines. Fixed a problem with BSD systems,
introdused by previous patch.
A bit different aproach for ut->ut_id and /dev/pts - original code
by Michael Zucchi, just inserted. Keeps 4 chars for ut_id.
1999-03-27 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_mode): Patch from Matthijs Melchior to support extended
foreground/background colours (the 'bright' set). Also support
un-setting render attributes individually.
1999-03-24 Erik Troan <ewt@redhat.com>
* gnome-pty.c (write_logout_record): Before writing a utmp record,
you need to reset the utmp file pointer (esp as we have multiple
utmp entries per process). ut->ut_id was also being set to a string
of 4 chars on /dev/pts systems, which makes the '\0' on the end
overwrite ut_user -- use a 3 character string instead.
* gnome_pty_helper.c (open_ptys): Set effective user and group ids
to real user and group before opening unix98 ptys (this forces the
proper owner/group on the /dev/pts file
1999-03-21 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_delete_line): Changed to properly handle the difference
between \EM and \E[M - it was checking the wrong thing for state.
1999-03-18 Federico Mena Quintero <federico@nuclecu.unam.mx>
* Makefile.am (libzvt_la_LDFLAGS): Updated library version number.
1999-03-18 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* -- MERGED IN ZVT_SCROLLSELECT BRANCH --
No longer binary incompatible (thanks Miguel :)
Framework for future extension similarly.
* zvtterm.h (struct _zvtprivate): Created new structure for
private data.x
* zvtterm.c (zvt_term_init): Changed to use "_zvtprivate" data for
scrollselect info.
(zvt_term_button_press): Ditto.
(zvt_term_button_release): Ditto.
(zvt_selectscroll): Ditto.
(zvt_term_motion_notify): Ditto.
(zvt_term_scrollbar_moved): Ditto.
(zvt_term_destroy): Free zvtprivate data on destroy. Do the input
handlers need destorying?
(zvt_term_init): Setup zvtprivate data on create.
* zvtterm.h: Added prototype for zvt_term_reset().
* zvtterm.c (zvt_term_reset): New function - external API to
vt_reset_terminal().
* vt.c (vt_reset): Removed terminal reset code into
vt_reset_terminal().
* vt.h: Added prototype for vt_reset_terminal().
* vt.c (vt_reset_terminal): New function - soft(hard) reset of
terminal.
1999-02-28 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.c (zvt_term_selection_clear): Changed header so it isn't
auto-documented.
(zvt_term_bell): Same.
(zvt_term_set_size): Add documentation.
1999-02-26 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.h: Include unistd.h, for pid_t.
1999-03-18 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zterm.c (main): Catch "destroy" signal to die on.
* zvtterm.c (zvt_term_closepty): Revert yesterdays' changes. As
suggested by ewt, catch for "destroy" signal to detect end of life
from window system.
1999-03-17 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (zvt_term_closepty): Make sure we raise a "child_died"
when the child is being terminated (and it existed). SIGCHLD just
wont raise it, because after this point it no longer exists (in
the 'children' list, see subshell.c).
1999-03-16 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (zvt_term_key_press): Changed all cursor keys to send
\E[x, rather than \EOx. Hell I dont know how this ever worked
really.
(vt_scroll_area): Scroll based on terminal width (as terminal
height is done), rather than on size of border window - border
width. Also properly handle PADDING setting and border width.
(zvt_term_key_press): Honour VTMODE_APP_CURSOR when outputting
cursor keys.
1999-03-12 Richard Hult <rhult@hem2.passagen.se>
* zvtterm.c (zvt_term_scroll_by_lines): New internal function.
(zvt_term_button_press): Add support for mouse wheel.
1999-03-11 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (get_ptys): Set close on exec flag for our pipes.
Otherwise we end up sharing these descriptors with sub-processes,
and thus gnome-pty-helper wont notice when we are gone until the
shells are killed.
1999-03-08 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_key_press): Add support for SHIFT-INSERT to
mean paste.
(request_paste): New routine, used in two spots now.
* subshell.c (zvt_init_subshell): Also reset SIGPIPE.
1999-02-24 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (zvt_init_subshell): Put the stuff on the right branch.
* (zvt_init_subshell): Reset the child signal handlers
to SIG_DFL and the job-control signals to SIG_IGN (to let subshell
set those up by itself).
1999-02-25 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_tab): Check for cursorx=width, and dont tab (unless
wrap is on). Also, after tabbing cursor, if cursox=width, then
dont linefeed. Handle wrap mode properly(?)
(vt_clear_line_portion): Range check input.
(vt_restore_cursor): Allow cursorx to be width.
* update.c (vt_draw_cursor): It is possible to for the cursorx
value to be 'off' the right hand edge of the screen by 1 character
outside of internal updates. Dont draw the cursor in this case
(should fix mc rh-border glitch). Wasn't pure afterall :)
1999-02-24 Timur Bakeyev <mc@bat.ru>
* gnome-utmp.c (write_logout_record): Fix for Linux systems and partly,
for Solaris.
1999-02-25 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_delete_chars): Make sure delete character is blank.
(vt_delete_chars): Range check input value to width of line.
(vt_insert_chars): Ditto.
Thu Feb 25 03:47:44 1999 Timur Bakeyev <mc@bat.ru>
* gnome-pty.h, gnome-utmp.c: Added function write_login_record as
opposit to write_logout_record.
Design rewritten. Supposed, should work on all platforms.
1999-02-24 Miguel de Icaza <miguel@nuclecu.unam.mx>
* vt.c (vt_set_screen): Removed call to vt_clear_lines here, as
the page flipping should not clear the screen.
(vt_restore_cursor): Do not restore the alternate screen when
issueing this command.
(vt_set_screen): Made the code clearer in the screen switching part.
1999-02-24 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zvtterm.c (zvt_term_button_press): Same as below fix for
triple-click. Otherwise hightlighted text wont actually be
selected if the mouse isn't dragged.
1999-02-23 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_button_press): Consider double-click as
VT_SELTYPE_MOVED. Closes critical bug report 315.
1999-02-22 Miguel de Icaza <miguel@nuclecu.unam.mx>
These fixes are from Chris Evans audit on gnome-pty-helper.
* gnome-utmp.c (update_dbs): Add check for malloc return value
here.
(update_dbs): 0-terminate ut->ut_host.
* gnome-pty-helper.c (open_ptys): Check for alloca return value.
(pty_add): Call memset after we check the value returned from
malloc.
(pty_add): Check for return value of strdup.
* gnome-pty-helper.c (sanity_checks): We were checking if stdin
was open twice instead of testing stdin and stdout
1999-02-23 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_parse_vt): Dont process more than VTPARAM_MAXARGS
parameters for all cases.
(vt_parse_vt): Make sure vt->argcnt is set on invocation of
callbacks.
1999-02-22 Elliot Lee <sopwith@redhat.com>
* zvtterm.c: Translate \n -> \r when pasting (fixes
pastes with newlines in them).
1999-02-21 Nuno Ferreira <nmrf@rnl.ist.utl.pt>
* Makefile.am (zterm_LDADD): Use libzvt.la without the path from
the topdir so that AM_MAKEFLAGS=-j4 works.
1999-02-21 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* vt.c (vt_resize): If we remove lines from the top of the buffer,
then make sure we also move the cursor up (but not beyond the top
of the screen).
(vt_resize): If we have reduced the size of the scrollback buffer
below the current displayed area, then make sure we reduce the
offset.
1999-02-18 Michael Zucchi <mzucchi@denr.sa.gov.au>
* vt.c (vt_scroll_up): Apply CLEARMASK to blank character (and
then actually use it).
(vt_scroll_down): Apply CLEARMASK to blank character.
(vt_delete_chars): When deleting characters, extend the attributes
from the end of the line (dont apply the latest attributes!).
(vt_insert_lines): Apply CLEARMASK to blank character.
(vt_delete_lines): Ditto.
(vt_clear_line_portion): Ditto.
(vt_newline): Ditto!
(vt_resize): Ditto (for vt_resize_lines calls).
(vt_insert_chars): Ditto for inserting blanks.
* vt.h (VTATTR_CLEARMASK): Mask to apply to the attributes to
generate a 'clear' character.
Thu Feb 18 03:29:00 1999 Timur Bakeyev <mc@bat.ru>
* gnome-utmp.c: Re-arrange source, so (suppose) it compilable on
both SVR and BSD. Everything #ifdef'ed. Removed dependences from
USE_SYSV_UTMP macro. Add update_utmp() function for BSD systems.
* gnome-pty.h: Remove USE_SYSV_UTMP macro.
* gnome-login-support.h: Add declarations from libutil.h for BSDI,
which has libutil.a, but not .h :(
* gnome-pty-helper.c: Add casting to caddr_t for msg_control to avoid
warnings.
* Makefile.am: Added $(UTIL_LIBS) to zvt dependences.
* test-utmp.c: Now it does login/logout.
1999-02-18 Michael Zucchi <mzucchi@denr.sa.gov.au>
* zterm.c (main): Added bad argument/-h usage instructions, and
'r' option to put the scrollbar on the right (changed the default
to left!).
* zvtterm.c (zvt_term_motion_notify): Record when selecting mouse
has moved.
(zvt_term_button_press): Make sure we fix selection/update if it
is only a single click.
* vtx.h (VT_SELTYPE_MOVED): Flag to indicate mouse has moved.
* zvtterm.c (zvt_term_button_release): Dont select anything if the
mouse hasn't moved.
(zvt_term_button_press): Dont re-render selection yet.
1999-02-17 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_size_allocate): Do not remove the PADDING
here. I need to figure out where the grid step information is
passed ot the Window Manager.
Wed Feb 17 12:20:21 1999 Maciej Stachowiak <mstachow@alum.mit.edu>
* gnome-login-support.c (login_tty): Replace an #elsif with an
#else in the fix below. D'oh!
* gnome-login-support.c (login_tty): On SVR4 systems, make sure to
allocate a controlling terminal. Since the right way to do this is
simply to open a terminal after calling setsid(), but we already
have it open at that point, reopen it and then close it.
1999-02-14 Tomas Ogren <stric@ing.umu.se>
* zvtterm.c: Fixed a tyop in the docs
Sat Feb 13 01:47:41 PST 1999 <jpaint@serv.net>
* zvtterm.c: don't draw if the zvtterm widget is not
drawable.
1999-02-09 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (zvt_close_msgfd): Implement with GList.
(sigchld_handler): Do not reset the child->pid here to zero, or
there wont be a way to eliminate this child from the list, and
thus waitpid test will get hossed.
* gnome-pty-helper.c (sanity_checks): Ignore SIGINT.
(shutdown_pty): record logout. Keep track of the utmp/wtmp
updating.
* subshell.c: Add support for split utmp/wtmp recording.
* zterm.c: log everything by default.
1999-02-09 Michael Zucchi <zucchi@zzedzone.mmc.com.au>
* zvtterm.c (zvt_term_set_blink): Remap true state to 1, false to
0, so XOR test works.
1999-02-07 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (receive_fd): Remove the getmsg usage, this was really broken.
(s_pipe): Split the creation of the pipe mechanism.
In SVR4 use pipe, on BSD use socketpair.
* vt.c (vt_restore_cursor): Only restore the cursor modes (this
does not include cursor tracking).
* zvtterm.c (zvt_term_size_request): I do not think the code for
set_grid_size_pending is working as it should. If you send
another size_allocate, it will get the broken 8/2 defaults. This
fixes gnome-terminal starting up in 8x2
1999-02-06 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* update.c (vt_set_wordclass): Fix loop end condition so it
doesn't drop last of a range, or single characters.
* zterm.c (main): Set word selection class so it will get url's ok.
* zterm.c (main): Use the zvt_term_new_with_size function to
create the widget.
* vt.c (vt_modeh): Set relative cursor mode.
(vt_model): Remove relative cursor mode.
(vt_gotoxy): goto position based on args.
(vt_goto): Handle relative origin mode for goto.
(vt_scroll): Reset cursor position when origin/size changed.
* vt.c: Added ESC[x;xf "horizontal and vertical position" command.
For ESCD do cursor down (IND), not ignore.
(vt_parse_vt): Store state back into vt->state so callbacks know
where they were called from.
(vt_nl): Support ESCE for "next line" function.
(vt_left): Always cursor left, at least 1.
(vt_right): Always cursor right, at least 1.
(vt_parse_vt): In state ESC[xxxY, handle embedded control codes by
executing them.
(vt_parse_vt): Support linewrap mode on/off.
(vt_modeh): Support linewrap setting ESC?7h
(vt_model): Support linewrap setting ESC?7l
(vt_restore_cursor): Restore mode/attributes and character set as
well as position.
(vt_save_cursor): Save mode/attributes and character set as well
as position.
1999-02-06 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_set_wordclass): User API call to set the
character class for words.
* update.c (vt_set_wordclass): New function, sets the bitmap used
to lookup word classes.
(vt_in_wordclass): Now uses a bitmap (in the vtx structure) to
determine which characters are part of a word.
(vtx_new): Initialise the wordclass to alphanumerics + "_".
* zvtterm.c (zvt_term_size_request): Set the minimum grid size to
8x2. 1x1 is useless.
* zterm.c (main): I want a blinking cursor, who changed it? :P
* zvtterm.c (zvt_term_init): Changed default init size to 80x24.
This doesn't change the resize behaviour.
(zvt_term_new): Changed the description to more accurately reflect
the inital size behaviour.
(zvt_term_size_request): Change sense of grid_width/height test -
to make sure its not negative or 0. Properly reset the
set_grid_size_pending flag off.
(zvt_term_set_font_name): Removed redundant "cleanup" label. Why
is everything reformatted wrong?
* update.c (vt_get_selection): Fixed calling vt_get_selection, so
a null *len is allowed.
* zvtterm.c (zvt_term_get_buffer): Update the documentation to
reflect the change from malloc/free to g_malloc/g_free.
(zvt_term_get_buffer): Do not set vx->selection_size when
returning the buffer contents.
(zvt_term_button_release): Removed useless 'len' argument to
vt_get_selection(). The api was int anyway, not gint.
* update.c: Changed to else/if when comparing line lengths. More
obvious that only one case will be executed (and hence memory wont
be lost).
Removed goto.
Removed g_malloc()/g_free() of runbuffer. Now statically
allocated, but grown if need be.
(vtx_new): Set runbuffer/runbuffer_size on init.
(vtx_destroy): Free runbuffer on destroy.
* zvtterm.h(zvt_term_new_with_size): New allocate-with-size api
call.
Thu Feb 4 16:34:03 1999 Owen Taylor <otaylor@redhat.com>
* vt.c (vt_mode): Add support for ESC[39m and ESC[49m
to reset foreground and background colors respectivly.
(Supported by Linux console and xterm among others)
1999-02-04 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_init): Set shadow to none. We should kill
this code, as it broke my hack to add the extra padding to make
the terminals readable.
Use PADDING bytes on the left as well to work as a padding region
(zvt_term_draw): Check against GTK_SHADOW_NONE
(zvt_term_expose): ditto.
1999-01-22 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell-includes.h (_XOPEN_SOURCE): Define as 1, not as nothing.
1999-01-17 Jeff Garzik <jgarzik@pobox.com>
* zterm.c:
s/gtk_container_border_width/gtk_container_set_border_width/
1999-59-15 Erik Troan <ewt@redhat.com>
* subshell.c, vt.h, vt.c: Use a separate keyfd for relaying
keystrokes. Normally this is identical to childfd, but this
allows the applications to abitrarily filter keystrokes before
they get to the application.
1999-01-12 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty-helper.c: Only define _XOPEN_SOURCE in IRIX>
1998-01-09 Jeff Garzik <jgarzik@pobox.com>
* subshell-includes.h, gnome-pty-helper.c:
Terminate some #if's.
1999-01-09 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell-includes.h: Provide the same header files as the
gnome-pty-helper to address the compilation problems on AIX.
* gnome-login-support.c: Use termios.h, not sys/termios.h
* gnome-pty-helper.c (path_max): PATH_MAX support for various
fashions of operating systems
1999-01-07 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c: Removed the defines that make gcc -ansi -pedantic
works as it breaks compilation on FreeBSD.
* gnome-pty-helper.c: Ditto.
* gnome-pty-helper.c (pty_remove): Return here instead of
continuing (this was causing pty-helper to die prematurely).
1999-01-03 Jay Painter <jpaint@serv.net>
* zvtterm.c: removed ifdefs so building without background pixmap
support is no longer a option; cleaned up the flickering a little
with scrolling when we have a background pixmap.
1999-01-03 Jay Painter <jpaint@serv.net>
* zvtterm.c, zvtterm.h: more widget cleanup, rearranged structure
to take up less memory by putting all the bitfields at the end of
the zvtterm structure (and breaking binary compatibility); fixed
a bunch of memory leads caused by not unref(ing) fonts, objects.
1999-01-03 Jay Painter <jpaint@serv.net>
* zterm.c: made the test program work better by properly duplicating
and setting up the environment for the forked pty.
* vt.c: fixed a resizing behavior so that the current line will
not get moved up into the scrolling buffer; instead, it will
destroy lines from the bottom of the terminal once it hits the
current line when moving top lines into the scrollback area.
1999-01-02 Jay Painter <jpaint@serv.net>
* vt.h, vt.c, update.c, zvtterm.c: fixed multiple buffer overruns
thanks to electric fence. Changed default color of terminal to
black on white.
* zterm.c: changed widget packing, and main window size hints to
accureately reflect terminal grid size.
1999-01-02 Jeff Garzik <jgarzik@pobox.com>
* gnome-pty-helper.c, subshell.c,
zterm.c, zvtterm.c:
Include _xxx_SOURCE defines for 'gcc -ansi -pedantic'
* gnome-pty.h:
removed global var login_name not referenced anywhere.
removed unnecessary comma.
* gnome-pty-helper.c: include autoconf alloca incantation
1998-12-31 Jay Painter <jpaint@serv.net>
* zvtterm.c, vtx.h, update.c: changed the way the zvtterm
widget preforms size requests to be more consistant with the
way other GTK+ widgets do -- that is, they only request their
minimum allocation size and let their parents allocate more.
Unfortunately, this scheme doesn't work well for a terminal
widget because it's hard for the parent widgets to know exactly
how much to allocate; therefore, there is an additional API for
setting the terminal grid size (zvt_term_set_size) which will
preform a widget resize to the appropriate grid dimentions.
1998-12-30 Jay Painter <jpaint@serv.net>
* zvtterm.c: fixed "unterminated macro 1511" syntax error
that I didn't catch during my last merge.
1998-12-30 Miguel de Icaza <miguel@nuclecu.unam.mx>
* vt.c (vt_tab): Ok, use the VTATTR_CLEAR for tabs, not just
"no-attributes". This fixes the tab problem with other colors.
Thanks to Jay for pointing this out.
1998-12-30 Jay Painter <jpaint@serv.net>
* memory.[ch]: removed! replaced with glib g_malloc, g_free
and friends; this is for code clarty and to also fix a nasty
bug that tried to free un-allocated memory when you resized
while scrolled up.
* vt.c, update.c: g_memory stuff all the way; removed all calls
to alloca;
* zvtterm.c: just some formatting changes here and there
1998-12-29 Jay Painter <jpaint@serv.net>
* zvtterm.[ch]: massive reformatting, added many meaningful
asserts, added gtk_widget_queue_resizes after font changes and
maybe in another place or two; added framework for getting this
widget to size itself like a normal GTK+ widget, but I havn't
implimented it yet. Replaced the alloca string allocations with
GString(s) because if I remember right once you've increased your
stack frame size, all stack frames called under it are at least
that size -- but then I could also be on drugs. I probably did
somthing else too...
1998-12-28 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (draw_back_pixmap): Do not reset the _tile to the
previous value. We probably do not care, as we have reset the
fill style anyways (and tile only makes sense if the fill is set
to GDK_TILED).
(zvt_term_get_capabilities): Only allow the pixmap settings to
take effect if the visuals are compatible.
(zvt_term_set_background): Even if we have support, make sure we
do not acknowledge any calls if _capabilities does not allow us to
use it.
Do not know why XSetTile does not accept a NULL pixmap though to
reset this value.
* vt.c (vt_tab): Fix for the tab problem reported by Alan. It
happens that tabs are transparent regarding attributes.
Wed Dec 16 16:52:53 1998 Owen Taylor <otaylor@redhat.com>
* zvtterm.c (zvt_term_init): Initialize timeout_id to -1.
1998-12-31 Jay Painter <jpaint@serv.net>
* zvtterm.c, vtx.h, update.c: changed the way the zvtterm
widget preforms size requests to be more consistant with the

preform a widget resize to the appropriate grid dimentions.
1998-12-30 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty-helper.c (open_ptys): Use pathmax, as the sysconfig
tty size does not include the whole pathname.
* vt.c (vt_tab): Ok, use the VTATTR_CLEAR for tabs, not just
"no-attributes". This fixes the tab problem with other colors.
Thanks to Jay for pointing this out.
1998-12-30 Jay Painter <jpaint@serv.net>

1998-12-09 Miguel de Icaza <miguel@nuclecu.unam.mx>
* update.c (vt_get_selection): Fixed the paste problems. We need
to set the selection_size when we set the selection
(vt_in_wordclass): Punctuation characters are not in wordclass
Wed Dec 9 05:39:05 PST 1998 Manish Singh <yosh@gimp.org>
* zvtterm.[ch]: fix for IC changes in new gtk. It compiles,
and zterm works, someone want to verify it is correctly fixed?
1998-12-05 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty-helper.c (sanity_checks): Figure out if file
descriptor 2 is valid, if not, then try using /dev/tty and
/dev/null as replacements.
(sanity_checks): Verify that descriptors 0 and 1 are valid.
1998-12-05 Havoc Pennington <hp@pobox.com>
* vt.h: Change name of "this" member to "this_line," so C++
doesn't puke. Add extern "C" stuff.
* vt.c: reflect change throughout
* update.c: same
* vtx.h: extern "C"
1998-12-05 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* zvtterm.c (zvt_term_get_buffer): New api function. Returns a
malloc'd block of memory containing buffer/scrollback contents as
a sequence of bytes.
* update.c (vt_select_block): New function, returns a malloc'd
block of memory containing the scrollback contents.
(vt_get_selection): Moved most of the code into vt_select_block.
Fri Dec 4 16:45:11 1998 Manish Vachharajani <mvachhar@vger.rutgers.edu>
* gnome-pty-helper.c: Don't bail out if we can't open /dev/tty.
Seems to cause problems.
Wed Dec 02 03:16:07 1998 George Lebl <jirka@5z.com>
* zvtterm.c: (vt_scroll_area) check for background pixmap in
addition to transparency to do the cheap ass scrolling hack by
repainting the entire window
Sun Nov 29 02:59:32 1998 George Lebl <jirka@5z.com>
* zvterm.[ch]: added function zvt_term_get_capabilities, which
returns the bitmask of capabilities supported by the zvt widget
right now, this is only the pixmap support, which is
ZVT_TERM_PIXMAP_SUPPORT
1998-11-26 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (get_ptys): Use n_read, just like gnome-pty-helper.
* gnome-pty-helper.c (main): Deal properly with read(). read
might return -1/EINTR for an interrupted system call. read might
return less bytes than requested and read might return 0 on eof.
* gnome-login-support.c (n_read): New utility routine to deal with
all of the read () system calls details.
* subshell.c (zvt_init_subshell): Init SIGCHLD before the first
fork.
* gnome-pty-helper.c: Duh. Test was wrong. Relaxed limits.
* zvtterm.c (zvt_term_title_changed_raise): Fix prototype.
* gnome-pty-helper.c (sanity_checks): New routine takes care of
making sure environment is sane for running a suid program.
Thanks to Pavel Kankovsky for providing sample code for resource
checks and signal checks.
(main): Check for open return value. Thanks
to Pavel Kankovsky again for pointing this out.
1998-11-26 Jeff Garzik <jgarzik@pobox.com>
* vt.c, zterm.c, zvtterm.c:
Replaced sprintf calls with g_snprintf.
Updated a couple hardcoded length values to instead of sizeof().
1998-11-24 Miguel de Icaza <miguel@nuclecu.unam.mx>
The following changes have been implemented after the comments
from Pavel Kankovsky (peak@kerberos.troja.mff.cuni.cz) who audited
the gnome-pty-helper code.
Now I understand why Theo says that most of us mere programmers
do not get properly aquainted with the proper Unix system call API.
* gnome-login-support.c (pty_open_slave_bsd): Set the owner and
group even if getgrnam fails due to a low memory condition on the system
* gnome-pty-helper.c: Make the pty_info->line information be a
character pointer instead of a static array.
(pty_add, pty_remove): fix accordingly.
(open_ptys): Size the array passed to openpty correctly: use
sysconf (_SC_TTY_NAME_MAX) if available or PATH_MAX otherwise.
dup2() might fail with EINTR, handle this case.
A couple of extra problems still remain, will fix those tomorrow.
1998-11-23 Jay Painter <jpaint@serv.net>
* zvtterm.c: added zvt_term_map & zvt_term_unmap so that the
terminal and its subwindows are mapped/unmapped properly.
1998-11-23 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-pty.h (USE_SYSV_UTMP): Define USE_SYSV_UTMP in the shared
header file
* subshell.c (zvt_shutdown_subshell): Duh, I was missing the tag
write. Protocol fixed. This should fix gnome-terminal for everyone.
* zvtterm.c (zvt_term_bell): Fix prototype.
1998-11-22 Jay Painter <jpaint@serv.net>
* zvtterm.c: widget now creates a separate term_window for the
terminal window. This is sized inside of the widget->window
so that the terminal widget has a relieved border. I also
cleaned up a couple of leaks and moved some stuff from the
_destroy method into the _unrealize method. Sorry Michael,
I tried to e-mail you before this commit but the mail bounced!
1998-11-21 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zterm.c: Made window global.
* zvtterm.c (zvt_term_get_bell): Fixed return if fail to be return
val if fail. Personally I can't imagine where you would ever need
this function.
(zvt_term_title_changed_raise): Function to actually raise the
signal, when we get called by the terminal.
* zvtterm.h: Fix zvt_term_bell prototype.
* vt.c (vt_bell): Changed to call callback with user_data.
vt.c: include <string.h> for strchr prototype.
* zvtterm.c (zvt_term_bell): Changed prototype/callback to supply
user-data (i.e. the widget pointer).
* zterm.c (main): Add support for title_changed event callback.
(title_changed_event): Set titles based on title_changed event.
* vt.c (vt_init): Init change_my_name and user_data to NULL.
(vt_set_text): Handle callbacks for setting titles.
* update.c: Fixed vx->user_data references.
* vtx.h: Removed user_data from struct _vtx. Avoid duplication.
Fixed all references.
* vt.h: Added change_my_name callback, for title changes. Added
user_data field (to be removed from vtx).
* zvtterm.c (zvt_term_title_changed): Dummy handler for
title_changed signal.
* zvtterm.h (struct _ZvtTermClass): Added title_changed callback.
* zvtterm.c (zvt_term_class_init): Added "title_changed" signal.
1998-11-20 Manish Vachharajani <mvachhar@vger.rutgers.edu>
* zvtterm.h:
* zvtterm.c: Added zvt_term_get_bell function
1998-11-19 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zvtterm.c (vt_hightlight_block): Removed. Function not used
anymore.
1998-11-18 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zvtterm.c (zvt_term_selection_received): Only scroll to bottom
if scroll on keystroke is set, now that it should be safe to do
so.
* vt.c (vt_scrollback_add): Properly adjust scrollbackoffset and
scrollbackold if extra data is added to the scrollback, and
scrollback is 'active' (scrollbackoffset != 0).
* update.c (vt_update): Handle edge condition when scanning
backwards at edge of scrollback/real buffers properly.
* vt.c (vt_scrollback_add): Force a newly added scrollback line to
slot into the right sequence if scrollback is active. This should
fix scrolling output when viewing scrollback. Only 3 @#$@ hours
later.
* zvtterm.c (zvt_term_bell): Definition of function.
(zvt_term_init): Set the new ring_my_bell pointer callback.
(zvt_term_set_bell): New function. Sets ring_my_bell or clears it
depending on the requested state.
* zvtterm.h (zvt_term_bell): New external function to beep in a
terminal-way.
* vt.c (vt_bell): Use the new ring_my_bell callback if it is set.
(vt_init): Set ring_my_bell to NULL on initialisation.
* vt.h (ring_my_bell): callback function for bell ringers.
1998-11-17 Martin Baulig <martin@home-of-linux.org>
* gnome-pty-helper.c, test-utmp.c (update_dgs): Only call this
function if USE_SYSV_UTMP is defined.
[NOTE: This is only some kind of hack since we define this
function conditionally to USE_SYSV_UTMP in gnome-utmp.c.]
1998-11-16 Walter Mueller <walt@pi4.informatik.uni-mannheim.de>
* gnome-utmp.c (write_logout_record): Changes for Solaris compilation.
1998-11-15 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zvtterm.c (zvt_term_selection_received): Always scroll to bottom
on non-empty paste. This 'hides' a bug where the screen list can
get corrupt. Not sure if its in the parser or the update code.
* vt.c (vt_dump): Replaced coded constant masks with defined
values.
(vt_parse_vt): Likewise.
(vt_resize): Likewise.
(vt_tab): Simplified processing. Dont try and over-write anything
onscreen, unless its empty.
(vt_parse_vt): Remove 'handled' loop from interpreter. It just
wasn't doing anything useful ...
(vt_parse_vt): Remove unecessary null-pointer check in state 5
case. Also force character to 7 bits when interpreting it.
* update.c (vt_line_update): Replaced coded constant masks with
defined values.
(vt_scroll_update): Likewise.
(vt_update): Likewise.
* vt.h: Removed VTATTR_CHANGED flag. This gives one extra
attribute bit.
(VTATTR_MASK): New mask - all attribute bits.
(VTATTR_DATAMASK): No attribute bits.
1998-11-13 Miguel de Icaza <miguel@nuclecu.unam.mx>
* subshell.c (sigchld_handler): Only call the previous signal
handler if it was set.
1998-11-14 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* vt.c (vt_cleareos): Fix ^[J command to clear in the right
direction.
(vt_resize): When expanding lines from scrollback, fill remainder
of line with attributes of last character.
1998-11-11 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_set_del_key_swap):
(zvt_term_key_press): Add support for swapping the sequences
emited by DEL and Backspace.
(zvt_term_set_del_key_swap): Actually implement it.
1998-11-10 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gnome-utmp.c (update_dbs): Add support for UTMPX
implementations.
Use getutid to find an available slot.
(write_logout_record): New function to write a logout record.
* vt.c (vt_closepty): Shutdown the pty properly (to register
logout state).
* subshell.c (zvt_shutdown_subshell): Ask the PTY helper to
write the logout record information.
* subshell.c (get_ptys):
* gnome-pty-helper.c: Use STDIN_FILENO to transfer protocol
information. Use STDOUT_FILENO to transfer file descriptors, as
some BSD kernels crash if you use the same socket for transfering
data and file descriptors (this information comes from Theo de
Raadt).
* subshell.c (sigchld_handler): Chain signal handlers.
Use waitpid with WNOHANG set to check for any of our known
processes.
* gnome-utmp.c (update_dbs): Clear the utmp structure, per Theo de
Raddt's recomendation.
1998-11-10 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_scroll_update): Get the scroll fill colour from the
corresponding new line, not the old line (the 'fill' is free, it
may as well more likely match what we want - even if it doesn't it
just slows it down a bit).
* vt.c (vt_reset): Changed vt_cleareos call to vt_clear_lines.
(vt_cleareos): Handle screen clear options properly, not just
'clear to end'.
(vt_insert_lines): Simplified clear condition - always clear
(mumble grumble).
(vt_delete_lines): Always clear line contents.
(vt_clear_lines): Remove VTATTR_CHANGED from update.
(vt_delete_chars): Remove VTATTR_CHANGED.
(vt_insert_chars): Ditto.
(vt_scroll_up): Ditto.
(vt_scroll_down): Ditto.
(vt_clear_line_portion): Ditto.
(vt_tab): Ditto.
(vt_parse_vt): Ditto.
(vt_newline): Ditto.
1998-11-10 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* vt.c (vt_down): Out by one on bounds checking against the bottom
of the screen.
1998-11-10 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* vtx.h (vt_scroll_area): Fix prototype for new 'fill' parameter.
* update.c (vt_scroll_update): Calculate the scroll expose colour
from the previous background colour on that line (or start of),
and pass that to vt_scroll_area. Make sure the line is 'cleared'
with the same colour. And by jove, we have it!
* zvtterm.c (vt_scroll_area): Take a new option 'fill' - specifies
the background colour to fill in the scrolled area.
1998-11-09 Jay Cox <jaycox@earthlink.net>
* zterm.c: replaced rindex with strrchr for portability.
1998-11-09 Martin Baulig <baulig@merkur.uni-trier.de>
* subshell.c, gnome-pty-helper.c: Include <sys/un.h> if we have it.
(CMSG_DATA): Define this if if is not already defined.
1998-11-09 Martin Baulig <martin@home-of-linux.org>
* gnome-pty-helper.c (struct pty_info): Added `line' field.
(shutdown_pty): Added logout code for FreeBSD.
(open_ptys): Added some code for FreeBSD.
* zterm.c: Added new `-l' command line parameter to make
the shell a login shell.
* gnome-login-support.h: Include <libutil.h> on FreeBSD.
* gnome-pty.h (GnomePtyOps): Make it explicitly start with 1.
* gnome-utmp.c (_HAVE_UT_USER, _HAVE_UT_TIME): Use this #ifdefs.
(WTMP_FILENAME): Define if not already defined.
(HAVE_LOGIN): If we have the login () function, call it - otherwise
use the pututline () ... code.
1998-11-09 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* gnome-login-support.h: Include pty.h only if it exists, or
util.h if that exists (for OpenBSD).
* zvtterm.c: More slight doco updates/spelling fixes.
1998-11-07 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* vt.c: Mods to the doco - bit more meat and better spelling :)
1998-11-06 Raja R Harinath <harinath@cs.umn.edu>
* subshell.c (receive_fd) [!HAVE_SENDMSG]: Fix typos.
* gnome-pty-helper.c (init_msg_pass) [!HAVE_SENDMSG]: New empty
function.

Pass `used_bsd' to pty_open_master_bsd.
* gnome-utmp.c (paths.h): Protect inclusion with HAVE_PATHS_H.
(UTMP_FILENAME): Ensure that it is defined.
From "Brandon S. Allbery" <allbery@ece.cmu.edu>.
1998-11-02 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c, vt.c: Added documentation to the API entyr points in
zvt and vt.
* gnome-pty-helper.c: New suid program that takes care of pty
allocation, permission setting and utmp/wtmp record updating.
* gnome-login-support.c: Utility functions to portably open pseudo
terminals. The code in this module is used by gnome-pty-helper.
* Makefile.am (libzvt_la_SOURCES): Do not install subshell.h this
is an internal header file.
Add helper program. Makie gnome-pty-helper program setuid root.
* subshell.c (zvt_resize_subshell), vt.c: Cleaned up the name
space.
Tue Oct 27 14:19:15 1998 George Lebl <jirka@5z.com>
(this is a detailed changelog even for the last commit)
* zvtterm.h: added transparent,shaded,pixmap_filename and background
pixmaps and zvt_term_set_background
* zvtterm.c: added get_desktop_window for getting the current desktop
window, get_pixmap_prop, for getting an arbitrary pixmap property
on a window load_pixmap_back to load a pixmap, create_shaded_pixmap,
to make a shaded background pixmap, draw_back_pixmap for drawing
the background, which is done in draw and expose, and sometimes in
vt_draw_text. the call to set background stuff is
zvt_term_background. scrolling is done by calling a redraw even for
the entire widget
Tue Oct 27 01:07:21 1998 George Lebl <jirka@5z.com>
* zvtterm.[ch]: transparency hacks, it's not 100% clean and probably
doesn't work well with enlightenment desktops. it isn't much code
but if you really really don't want it (it doesn't affect the
normal operation at all) you can change a define in zvtterm.h,
it still needs a lot of cleanup and I hope that committing it will
get people to make it work with their windowmanagers (hint hint
raster)
* zvtterm.c,update.c: add headers to avoid warnings
1998-10-24 Martin Baulig <martin@home-of-linux.org>
* update.c: Only #include <alloca.h> if we `HAVE_ALLOCA_H'.
1998-10-22 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_update_rect): Was going to the wrong next node when
starting the screen list.
(vt_update_rect): Bounds-check csy - cey to height.
(vt_line_update): Removed assertion about runbuffer (alloca
doesn't return null).
(vt_line_update): Add node->next==NULL assertion to check for
end-of-list.
1998-10-21 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zterm.c (main): Set window hints/minimum size. Now the terminal
can be resized smaller! (should this be done to gnome-terminal?)
* vt.c (vt_resize): Make sure widened lines are cleared with a
blank character.
* lists.c (vt_list_remtail): This would never have worked. Just
lucky I never used it! Changed tail to tailpred.
(vt_list_addhead): This would never have worked either. Changed
tailpred to head *sigh*.
* vt.c (vt_scrollback_add): Changed to static.
(vt_dump): Changed to static.
* memory.h (vt_mem_unget): Add vt_mem_unget() prototype.
* memory.c: Include "memory.h" for prototypes.
* vt.c (vt_resize): Recover old scrollback lines if they exist,
and the view is getting bigger.
* memory.c (MEM_BLOCK_ALIGN): New constant - defines alignment of
allocations. Pointers need to align to this.
1998-10-20 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c: Include (missing) alloca.h.
(vt_line_update): Handle line size changes (i.e. if rendering
scrollback from before a resize). Removed the g_return_if_fail
for line size mismatch.
1998-10-19 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_line_update): Toggle, not OR reverse bit, for
rendering selected areas.
(vt_line_update): Typo in bitmask was stripping most attributes
from each character (7fff000->7fff0000).
Sun Oct 18 19:03:47 1998 Owen Taylor <otaylor@gtk.org>
* zvtterm.c: Changes to match the new GTK+ selection
handling API.
1998-10-18 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_fix_selection): When selecting by character, use
the same start-of-selection criteria as used with selection-by
word (stops the last character on a line from always being
selected).
(vt_scroll_update): Removed some bulky comments.
* vtx.h: Removed vt_draw_text_select prototype.
* update.c (vt_fix_selection): When selecting by word or
character, force the initial selection to contain at least 1
character.
(vt_line_update): Removed warnings: Removed noclear, unused variable.
(vt_scroll_update): Changed to static.
(vt_update): Typecast list references to struct vt_line *'s.
(vt_update): Removed un-used 'count'.
(vt_in_wordclass): Changed to static.
(vt_expand_line): Changed to static.
(vt_draw_selection_part): Changed to static.
(vt_draw_text_select): Force re-render of selected block's
background, when rendering the selection.
(vt_line_update): Integrated 'selection' rendering into here. Now
the code can properly determine exactly the screen rendering
attributes before they are rendered.
(vt_draw_text_select): Removed. Functionality integrated into the
vt_line_update routine.
* zvtterm.c (zvt_term_button_press): Ignore button presses when
CTRL is activated. This interferes with the pop-up menu in
gnome-terminal (semantically it makes no sense to support
selection with any qualifiers anyway).
(zvt_term_button_release): Likewise for button up.
* TODO: Cleaned out some done todo's.
* zvtterm.c (vt_draw_text): Doh! Forgot to remove some debug.
1998-10-15 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* zvtterm.c (zvt_term_scroll): Some code here broke the new update
stuff. scrollbackold should *never* be set outside of the update
routine.
(zvt_term_selection_clear): Modularised what had been, removed the
fixme (calls vtx_unrender_selection()).
(vtx_unrender_selection): Killed FIXME.
(zvt_term_draw): Always force re-draw (through 'in_expose').
(vt_draw_text): Change the sense of the dont-draw-background
condition. Always redraw background for expose events (will slow
down refresh though - FIXME: the screen representation needs to be
cleared to match the window, even for refresh).
1998-10-14 Michael Zucchi <zucchi@zzedzone.fsi.com.au>
* update.c (vt_line_update): Fix back_match determination. Only
match on all attributes for any blank rendering characters. When
this is the case the area behind text will not be cleared (often
twice-cleared otherwise).
* zvtterm.c (vt_draw_text): Hopefully properly fixed the 'dont
clear the background if we've already cleared the background
optimisation' bugs.
* update.c (vt_scroll_update): Removed 'fn' - first node of update
scroll area. No longer reliable or useful - due to scrollback
changes.
(vt_update): Integrated scrollback update within the same main
loop(s). Now scrollback should have the same performance as
normal scrolling. Has a (messier) problem with using scrollback
and screen update, which should be addressed with the scrollback
counter/bar elsewhere.
* vt.c (vt_tab): Change tab behaviour somewhat. Dont overwrite
attributes of existing characters. Dont blank beyond the first
space encountered [also, dont affect attributes]. Cleaned up code
a little bit.
* update.c (vt_update_rect): Make this take into account
vx->vt.scrollbackoffset when rendering the rectangle.
(vt_draw_cursor): Make sure the cursor is turned off when
scrolling (using scrollbackold rather than scrollbackoffset).
* zvtterm.c (zvt_term_scrollbar_moved): Only update 'scrollback'
mode, rather then refresh.
1998-09-24 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_feed): New routine. Used to feed
information to a zvtterm from the application.
* zvtterm.h: Changed the timeout it to be integer.
1998-09-14 Raja R Harinath <harinath@cs.umn.edu>
* subshell.c (close_msgfd): Change prototype to agree with
declaration (use `pid_t', not int).
1998-20-14 Erik Troan <ewt@redhat.com>
* zvtterm.c, zvtterm.h: added optional automatic scrolling
on keystrokes and/or output
1998-40-08 Erik Troan <ewt@redhat.com>
* subshell.c (pty_open_slave, pty_open_master): Set close-on-exec
flag for slave and master file descriptors
* handle SIGCHLD for proper termination detection
1998-09-04 <nicholas@cefiro.cs.nthu.edu.tw>
* vt.c (vt_goto): reset vt->cursorx or vt->cursory to zero
when it is negative number
1998-08-31 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_scroll): Clear any pending cached
information about scrollback when the user has triggered a
scroll view change.
1998-26-31 Erik Troan <ewt@redhat.com>
* vt.c (process_vt): accept : as a parameter seperator,
not just ; (xterm does, linux console doesn't; we're
supposed to be TERM=xterm, right?)
* vt.c (vt_clear_lineportion): made ^[[K handle parameters
properly (only ^[[0K was supported)
* vt.c (vt_delete_lines): cells containing spaces were
never updated; if the attribute is being changed they
need updating, however
1998-08-28 Erik Troan <ewt@redhat.com>
* vt.c (process_vt): wrapped some debugging printf()
statements with d()
* vt.c (process_vt): don't let ^]*X (w/ X >= 0x80)
segv the box
* vt.h: made the parameter stuff unsigned chars
1998-08-26 Erik Troan <ewt@redhat.com>
* zvtterm.c (vt_draw_text): attempted vx->back_match
optimization was incorrect, and to ghost selections
1998-07-25 Jonathan Blandford <jrb@redhat.com>
* zvtterm.c (zvt_term_realize): Changed GdkIM*Nothing to
GDK_IM_*_NOTHING to reflect the changes in gdk.
1998-07-19 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_init): Initialise in_expose variable at
startup.
* update.c (vt_draw_cursor): Force back_match==0 when drawing
cursor - forces screen update.
* zvtterm.c (vt_draw_text): Dont clear the background, if the
screen already has the right colour [cleared], or we're in expose
events.
(zvt_term_expose): Set in_expose around expose events. Optimises
text drawing.
* update.c (vt_line_update): Cleaned up logic a little. Also, now
scans back buffer to find out if it is already clear, set
vx->back_match if it is.
1998-07-05 Nuno Ferreira <nmrf@rnl.ist.utl.pt>
* zvtterm.c (zvt_term_scroll): Check bounds when scrolling. You
could Shift-PageDown while already on the last line and then would
require 2 Shift-PageUp to start scrolling up again.
1998-06-15 Michael Zucchi <zucchi@zzedzone.box.net.au>
* update.c (vt_line_update): Was usually drawing 1 more character
than necessary.
(vt_draw_cursor): Map NUL or TAB to ' ' when drawing the cursor.
* zvtterm.c (zvt_term_key_press): Insert \033 before backspace for
meta-bs.
(zvt_term_key_press): Same for delete. Should probably be a
cleaner/more generic way to do this.
* vt.c (vt_gx_set): New function, sets the current font remappings
for G0 to G3 font.
(vt_init): Initialise vt->Gx, and vt->G[x]
(vt_init): Initialise vt_remap_dec[]
(vt_alt_start): Removed old redundant code. Now sets G[1] charset
as current.
(vt_alt_end): Changed to reset to G[0] charset.
(vt_reset): Reset Gx and G[x]
Sun Jun 14 14:07:34 1998 Tom Tromey <tromey@cygnus.com>
* Makefile.am (INCLUDES): Look in intl build directory. Don't
unconditionally look in support directory (configure will
determine whether this is needed).
Sat Jun 13 21:08:50 1998 Tom Tromey <tromey@cygnus.com>
Fixed all -Wall warnings:
* zterm.c: Include <stdlib.h> for atoi().
* zvtterm.c: Include <string.h> for memset().
1998-06-10 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_set_color_scheme): Changed background to
colour index 17 - colour index 18 doesn't exist!
(zvt_term_readdata): Removed the 'read failed' message.
* vt.c (vt_set_screen): Clear alternate screen on a switch.
* update.c (vt_draw_selection_part): Check the line is on-screen
before trying to re-render it. Fixes a nasty segfault.
(vt_line_update): Added some sanity checks to ensure segfaults are
banished.
1998-06-07 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_key_press): Added debug macro around the key
press printf.
(zvt_term_key_press): Changed the ctrl-space handling code, so the
default case doesn't grow into another switch statement to handle
all possible cases [which is what the existing switch is for].
* vt.c (vt_delete_line): For reverse scroll, compare to
vt->scrolltop, and not 0 - fixes reverse scroll in pine.
1998-06-01 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_key_press): Handle control-space.
Mon Jun 1 19:44:25 CEST 1998 Eckehard Berns <eb@berns.prima.de>
* zvtterm.c: added input context to support deadkeys.
Mon Jun 1 17:34:41 CEST 1998 Eckehard Berns <eb@berns.prima.de>
* zvtterm.c (zvt_term_key_press): added GDK_Mode_switch and
GDK_Multi_key to the switch statement to avoid [ff..] when pressing
AltGr or Multikey
1998-05-25 Miguel de Icaza <miguel@nuclecu.unam.mx>
* update.c (vt_get_attr_at): New function, returns the
attribute/char pair at a given column/row.
1998-05-23 Michael Zucchi <zucchi@zzedzone.box.net.au>
* vt.c (parse_vt): Looks up process() function at start of loop,
enabling the rest of the routine to be 8 bit clean.
1998-05-21 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_draw): Implement a draw handler.
1998-05-12 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_selection_clear): Added call to
gtk_selection_clear() to let gtk know the selection has been
cleared.
(zvt_term_button_release): Changed to use event->time rather than
GDK_CURRENT_TIME in selection owner set.
1998-05-10 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_set_font_name): Removed "loading xxx font"
message. Probably needs some fallback if it can't load a font
... better than the one it has.
(vt_draw_text): Only set 'bright' colours, if a bold equivalent exists.
* update.c (vt_draw_cursor): only draw/undraw cursor if not
scrolled back at all.
* zvtterm.c (zvt_term_button_release): Added GDK_SHIFT_MASK check
before reporting mouse up events.
* update.c (vt_draw_selection_part): Changed to use rendered
selection, rather than inverting the rectangle. May be slower for
detailed screens. Some of the arguments are now not used.
* vtx.h: Added vt_draw_cursor() prototype.
* zvtterm.c (vt_draw_text): Expanded to use 5 bit colour
selection. Put back in old default-colour handling code - needed
for new cursor rendering algorithm. Now swaps the referenced gc's
rather than the gc's referenced colour,when inverse mode set.
Should fix some rendering glitches.
* vt.c (vt_mode): removed VTATTR_FORE/BACK_SET bit settings, as
these bits no longer exist.
* vt.h : redordered VTATTR_* bits. Modified fore/background
colour to have 5 bits.
* zvtterm.c (vt_cursor_state): Calls vt_draw_cursor() to render
the cursor.
* update.c (vt_get_selection): Fixed bug where it added the first
line of a selection twice to the selection buffer.
(vt_draw_text_select): Fixed update bug when refreshing could
corrupt first and last line of a selection.
(vt_draw_cursor): New function. Draws the cursor onto the
display. Draws the cursor using vt_draw_text() and not an
inverted box.
* zvtterm.c: Fixed up calls to vt_draw_selection(), to call
vt_fix_selection() where appropriate.
* update.c (vt_draw_selection): Removed call to
vt_fix_selection(). Now must be performed explicitly by caller.
1998-05-09 Michael Zucchi <zucchi@zzedzone.box.net.au>
* update.c (vt_update): Changed behaviour slightly for scroll-wrap
lines. Always update them.
* vt.c (vt_delete_chars): Fixed out-by-1 error in scrolling the
deleted charcters into place.
1998-05-08 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_set_color_scheme): Set the GdkWindow color
to the default background of the terminal. This avoids the
flashing gray when switching desktops.
1998-05-06 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (vt_draw_text): Use the default background/foreground
unless an attribute has been specified.
default_red, grn, blu: The colors 16 and 17 are default foreground
and default background.
Wed May 6 13:15:16 1998 Tom Tromey <tromey@cygnus.com>
* subshell.c: Include <config.h>. Conditionally include
<sys/select.h>.
1998-05-04 Michael Zucchi <zucchi@zzedzone.box.net.au>
* subshell.c (pty_open_master): Removed warnings.
* vt.c (vt_model): Added case 47 - alternate screen off.
(vt_modeh): Added case 47 - alternate screen on.
(vt_set_screen): New function. Sets the current screen.
(vt_resize): Added code to handle resize of alternate screen too.
(vt_scroll_up): Only add to scrollback if we are on the primary
screen.
(vt_reset): Resets screen to primary.
(vt_destroy): Added cleanup for alternate screen and image buffer.
* vt.h (VTMODE_ALTSCREEN): New definition. Covers alternate
screen switching.
1998-05-03 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zterm.c (main): Allow window to be shrinked when the font
changes.
* zvtterm.c (zvt_term_key_press): Add support for checking the
scrollback contents with shift-pgup, shift-pgdn in zvtterm.
1998-05-03 Michael Zucchi <zucchi@zzedzone.box.net.au>
* vt.c (vt_resize): Now calls resize_subshell() instead of calling
the ioctl directly.
* subshell.h: New file. Defines functions in subshell.c.
* subshell.c: New file. Includes init_subshell() and
resize_subshell() commands. Taken from 'mc' source tree.
* vt.c (vt_forkpty): Changed to use init_subshell() call from
subshell.c. No longer needs forkpty() function!
1998-05-02 Michael Zucchi <zucchi@zzedzone.box.net.au>
* vt.c (vt_swap_buffers): Removed. Not needed in the end.
* update.c (vt_scroll_update): Cleaned up some dead code.
(vt_scroll_update): Added code to perform scrolling of on-screen
image buffer.
(vt_line_update): Modified to use screen image buffer to optimise
updates. Seems to work very well!
1998-05-01 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_set_color_scheme): Add support for changing
the color set in the terminal.
(zvt_term_key_press): Add support for handling meta-key, for us,
emacs users :-).
Thu Apr 30 23:19:07 1998 Tom Tromey <tromey@cygnus.com>
* forkpty.c (openpty): Removed buffer, buflen, and grbuffer
variables. Correctly call getgrnam.
1998-04-30 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.h: Use unsigned ints for the flags.
* zvtterm.c (vt_cursor_state): Test for drawability.
1998-04-30 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (zvt_term_realize): Put GDK_POINTER_MOTION_MASK back
in, because we *ARE* interested in the events even when the button
isn't pressed. Otherwise the mouse doesn't un-blank :)
1998-04-29 Miguel de Icaza <miguel@nuclecu.unam.mx>
* zvtterm.c (zvt_term_realize): Removed the
GDK_POINTER_MOTION_HINT_MASK, as this was preventing the motion
from being reported back to the application; Removed the
GDK_POINTER_MOTION_MASK, as we are only interested in the events
when the button is held pressed.
(zvt_term_button_press): If shift key is pressed, then do not try
to report the button operations to the application (standars
behaviour :-)
(zvt_term_readdata): signal_emission might have killed this
process, do not call zvt_term_fix_scrollbar (ie, do a return on
the if-part for the dead process).
1998-04-28 Miguel de Icaza <miguel@nuclecu.unam.mx>
* vt.c (vt_newline): Initialize the whole array, as it can be
accessed past the screen size when the whole line is selected.
* zvtterm.c (zvt_term_readdata): Always show the cursor if
blinking has been disabled.
1998-04-30 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (vt_draw_text): Bold now renders 'bright' colours.
This is really only necessary (?) to emulate the use of the linux
console colours.
(vt_scroll_area): Does not clear the scrolled area exited space
anymore. Doesn't seem to be needed and cleans up scrolling.
* vt.c (vt_swap_buffers): New function. Not used yet. Working on
some very experimental update optimisation code. Maybe it will
speed things up a little <maybe>.
* update.c (vt_update_rect): Added range check for cex/csx. Could
be 1 character too large from expose event.
* zvtterm.c (zvt_term_readdata): *ALWAYS* turn the cursor back on
after an update. This must have got lost somewhere and was the
cause of the "blinking cursor usually off" bug that's been giving
me the shits :) Ahhhh, thats much better.
(vt_draw_text): Removed the need for the "VTATTR_FORE/BACK_SET"
flag. All it needed was a changed VTATTR_CLEAR define :)
Check it works properly though Miguel?
* vt.c: Removed some unecessary prototypes/comments.
Oh dear, its tommorow already :(
1998-04-29 Michael Zucchi <zucchi@zzedzone.box.net.au>
* vt.c (vt_scrollback_set): Changed back to the way it was and
also fixed the boundary condition. It is safe to call vt_mem_push
with a null location.
1998-04-28 Miguel de Icaza <miguel@nuclecu.unam.mx>
* vt.c (vt_scrollback_set): ln might be null after calling
vt_list_remhead, only execute vt_mem_push if ln is not null.
Michael, I do not know if this is the correct fix, could you check this?
* zvtterm.c (zvt_term_forkpty): set term->input_id to the file
descriptor of the chid.
1998-04-28 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zterm.c (child_died_event): New function, exits. This is the
signal handler for the "child_died" event.
* zvtterm.c (zvt_term_destroy): Added call to zvt_term_closepty
and vtx_destroy, to clean up emulator resources. Not sure if its
working right though.
(zvt_term_init): Removed some redundant code.
(zvt_term_child_died): Default signal handler for child death.
Does nothing.
(zvt_term_readdata): Emits "child_died" signal when read fails.
(zvt_term_class_init): Added "child_died" signal creation to
class.
* vt.c (vt_init): Sets the line number on initialisation of
lines. Maybe cleaner rendering on startup?
* zvtterm.c (zvt_term_destroy): Added call to vtx_destory.
* vt.c (vt_destory): New function. Cleans up memory associated
with vt run-time. Scrollback and lines. Closes child file
descriptor.
* update.c (vtx_destroy): New function. Cleans up the vtx
structure and free's it.
* zvtterm.c (zvt_term_killchild): New function. Calls
vt_killchild().
(zvt_term_forkpty): Checks validity of arguments. Also doesn't
allow a 'forked terminal' to fork again.
(zvt_term_closepty): New function. Close the child's process
master terminal, and removes the gdk input handler. Logical
inverse of zvt_term_forkpty()
* vt.h (vt_closepty): Added api functions killchild/closepty.
Perhaps it should also SIGHUP the child?
* vt.c (vt_killchild): New function. Sorry about the name.
Equivalent of 'kill(2)'.
(vt_closepty): Inverse of forkpty(). Just closes the master pty.
* zvtterm.h: Added fore_last and back_last to keep track of the
last foreground/background colour used in the fore/back_gc's.
* update.c (vt_update): Added initialisation of fn and firstline
so that gcc won't complain about logic it couldn't follow.
* zvtterm.c (vt_scroll_area): Clears the scrolled area using the
term->back_gc, which cleans up scrolling.
(vt_term_realize): Initialises fore_last/back_last.
(vt_draw_text): Removed static variables last_fore, last_back to
term->fore_last, term->back_last.
1998-04-27 Miguel de Icaza <miguel@nuclecu.unam.mx>
* vt.h (VTATTR_BACK_SET): Added two new attribute flags to
indicate if explicit foreground or background have been set.
* zvtterm.c (zvt_term_class_init): New overwritten method:
unrealize
(zvt_term_unrealize): Relese resources allocated on the realize
method.
(zvt_term_realize): Allocate a color context for the foreground
and one for the backgroudn; Allocate colors with the gdk color
context code.
(vt_draw_text): Add color support.
* vt.c (vt_mode): fix, process any number of arguments to the mode
escape sequence.
* zvtterm.c (zvt_term_key_press): Backspace sends ^H; Delete sends
\177, and KP_Delete sends \033[3~.
1998-04-27 Michael Zucchi <zucchi@zzedzone.box.net.au>
* zvtterm.c (vt_scroll_area): Generates and processes graphics_expose
events when scrolling from off-window areas.
* update.c (vt_update_rect): Modified to keep old state of cursor
on exit.
(vt_update): Modified to keep old state of cursor on exit.
* zvtterm.c (vt_cursor_state): Modified to return the previous
state of the cursor.
1998-04-26 Michael Zucchi <zucchi@zzedzone.box.net.au>
* memory.c: renamed mem_* functions to vt_mem_* functions.

Renamed mem_* functions to vt_mem_* functions.
(vt_scrollback_set): New function.
(parse_vt): Now reads \E] command - set text options, although
does not process it.
Multiple arguments were being passed to \EM command
