gitk: persist position and size of the Tags and Heads window
Revert "gitk: Only restore window size from ~/.gitk, not position"
When a file is selected in the file list, the diff window scrolls to the
corresponding section. The administrative data needed for this purpose
is extracted from the 'rename from', 'rename to', and 'copy to' lines.
Escaped file names are unescaped for this purpose. However, the lines
shown in the diff window are left in the escaped form. This is not very
pleasing. Replace the escaped form by the unescaped form.
Add a section to treat the 'copy from' case.

The Tags and Heads window always opens at a default position and size,
requiring users to reposition it each time. Remember its geometry
between sessions in the config file as `geometry(showrefs)`.
Note that the existing configuration is sourced in proc savestuff
right before new settings are written. This makes the old settings
available as local variables(!) and does not overwrite the current
settings. Since we need access to the global geometry(showrefs), it
is necessary to unset the local variable.

This reverts commit b9bee11526 (gitk: Only restore window size from
~/.gitk, not position, 2008-03-10).
The earlier commit e9937d2a03 (Make gitk work reasonably well on
Cygwin, 2007-02-01) reworked the window layout considerably. Much of
this became irrelevant around 2011 after Cygwin gained an X11 server
and switched to a supportable port of the Unix/X11 Tcl/Tk (it is now
on the current 8.6 code base).
Part of the necessary change was to restore the window size across
sessions, but the position was also restored. This raised complaints
on the mailing list[*], because Gitk was opened on the wrong monitor.
b9bee11526 was the compromise, because it was only the size that
mattered for the Cygwin layout engine to work.
I personally, find it annoying when Gitk pops up on a random location
on the screen, in particular, since many other applications restore
the window positions across sessions, so why not Gitk as well? (I do
not operate multi-monitor setups, so I cannot test the case.)

gitk sets no size limit on its configuration dialog, allowing the user
to collapse the window so almost nothing is visible. The geometry
manager sets an initial size so all the widgets are visible, though
ignores the potentially very long text in the entry widgets in doing so.
Let's use this initial size as the minimum. The size information is
computed in Tk's idle processing queue, so a wait is required.

gitk's configuration dialog uses a large number of widgets, and this
code is hard to read as there is no easily recognizable grouping or
breaks. Help this by adding space between items that occupy a single row
in the dialog.

gitk's configuration dialog can be resized, but this does not expand the
space allocated to any widgets. Some items may have long lines of text
that would be visible if the widgets expanded, but this does not happen.
The top-level container uses a two column grid and allocates any space
change equally to both columns. However, the configuration pages are
contained in one cell so half the additional space is wasted if
expanding. Also, the individual configuration pages do not mark any
column or widgets to expand, so any additional space given is just used
as padding.
Collapse the top-level page to have one column, placing the "OK" and
"Cancel" buttons in a non-resizing frame in column 1 (this keeps the
buttons in constant geometry as the dialog is expanded). This makes all
additional space go to the configuration page.
Mark column 3 of the individual pages to get all additional space, and
mark the text widgets in that column so they will expand to use the
space. While we're at it, eliminate or simplify use of frames to contain
column 2 content, and harmonize the indents of that content.
prefspage_general adds a special "spacer" label in row 2, column 1, that
causes all of the subsequent rows with no column 1 content to indent,
and this carries over to the next notebook tab (prefspage_color) through
some undocumented feature. The fonts page has a different indent, again
for unknown reason. The documented approach would be to use -padx
explicitly on all the rows to set the indents.

gitk allows configuring a particular theme in its configuration file
(default on linux: ~/.config/git/gitk), but offers no ability to modify
this from gitk's configuration editor. Let's add this to the color
configuration page.
Present the offered themes in a list, and allow choosing / modifying a
theme definition file ($themeloader). Update the list of themes if the
theme file is modified, and update the theme if specifically requested
(by default, just change the value for use after gitk is restarted).
Any theme definition file can change the global options database,
affecting potentially any theme. So, the ultimate configuration should
have either
- no theme definition file (themeloader = {}), and a native Tk, theme,
or
- themeloader naming a valid file, and $theme naming a theme defined by
that file.
But, there is no trivial way to enforce the above. Shrug.

gitk currently accepts a single themeloader file via the config file,
and will source this with errors reported to the console. This is fine
for simple configuration, but will not support interactive theme
exploration from the gui. In particular, a themeloader file must be
sourced only once as the themes defined cannot be re-defined. Also,
errors must be handled rather than just aborting while printing to the
console. So, add a proc to handle the above, supporting expansion of
the gui config pages.

gitk allows searching for commits with various criteria, and provides
up/down search buttons to facilitate this search. These buttons are
labelled with bitmaps, and those bitmaps are not always recolored
correctly for the ui scheme as the theme colors are not known. Let's
just use text labels on these, allowing the styles to handle any
coloring needed. Use utf codepoints for the arrows, presuming that these
code points are available in the selected font.

gitk maintains a stack of commit ids visited, and allows navigating
these using a pair of buttons shown with arrows using bitmaps. An attempt
is made to recolor these bitmaps to handle different color schemes, but
this is unreliable across multiple themes as the required colors are not
universally known. Let's just use text labels for these buttons,
allowing the themes to recolor the text along with everything else. Use
utf code points for the text, presuming that these arrow glyphs are
available in the selected font.

gitk uses themed widgets with a user selected theme, but also invokes
tk_setPalette to configure colors for the non-themed widgets including
the menubar. However, themes in general are expected to configure
those colors already. The builtin themes (default, alt, clam, classic on
unix/X11) all have compatible colors, and need no such reconfiguration,
and (most, if not all) available themes set the options database for this
purpose as well. Furthermore, gitk in the past avoided invoking
tk_setPalette on Windows to avoid some issues.
So, let's stop calling tk_setPalette everywhere, and just rely upon the
selected theme (possibly user installed) to have set all needed colors.
Note: if a user installs more than one theme using $themeloader, the last
one installed will have defined the colors to be used. Those colors will
probably be incorrect for any other set, including Tk's builtin set.

gitk uses themed tk, but has no capability to alter the theme defined
by Tk. While there are documented ways to install other themes, and
to make one the default, these methods are obscure at best. Instead,
let's offer two config variables:
- theme this is the name of the theme to use, and must be available.
- themeloader - this is the full pathname of a tcl script that
will load one or more themes into the Tk namespace.
By default, theme is set to the theme active when Tk is started, and
themeloader = {}. These variables must be defined to something else to
have any user visible effect.

On MacOS, a "wish" application started from the terminal opens in the
background, thus doesn't match user expectation that a newly-launched
application ought to be placed in the foreground. To address this
shortcoming, both gitk and git-gui use Apple Events to send a message to
"System Events" instructing it to foreground the "wish" application by
PID.
Unfortunately, MacOS 10.14 tightens restrictions on Apple Events,
requiring explicit granting of permission to control applications in
this fashion, and apparently such granting for "Automation" is not
allowed at all[1]. As a consequence gitk crashes outright at launch time
with a "Not authorized to send Apple events to System Events" error,
thus is entirely unusable on "Mojave".
In contrast, git-gui does not crash since it deliberately[2] catches and
ignores Apple Events errors. This does mean that git-gui will not
automatically become the foreground application on "Mojave", which is a
minor inconvenience but far better than crashing outright as gitk does.
Update gitk to catch and ignore Apple Events errors, mirroring git-gui's
behavior, to avoid this crash.
(Finding and implementing an alternate approach to foregrounding the
"wish" application on "Mojave" may be desirable but is outside the scope
of this crash fix.)

Tcl/Tk 9.0 has been released, and has shipped in Fedora 42. Prior
patches in this sequence have addressed known incompatibilities, so gitk
is now operating with Tcl9. So, let's allow Tcl9.
Signed-off-by: Mark Levedahl <mlevedahl@gmail.com>
gitk in the prior commit learned to apply -profile tcl8 to all input
data streams, avoiding errors on non-binary data streams whose encoding
is not utf-8. But, gitk also consumes binary data streams (generally blobs
from commits), and internally decodes this to support various displays.
With Tcl9, errors occur in this decoding for the same reasons described
in the previous commit: basically, the underlying data was not validated
to conform to the given encoding, and this source encoding may not be
utf-8. gitk performs this decoding using Tcl's '[encoding convert from'
operator.
For example, the 7th commit in gitk's history has the extended ascii
value 0xA9, so
gitk 9a40c50c1e
in gitk's repository raises an exception. The error log has:
unexpected byte sequence starting at index 11: '\xA9'
while executing
"encoding convertfrom $diffencoding $line"
(procedure "parseblobdiffline" line 135)
invoked from within
"parseblobdiffline $ids $line"
(procedure "getblobdiffline" line 16)
invoked from within
"getblobdiffline file6 9a40c50c1e05c0658b7a7c68b56d615eb6f170dd"
("eval" body line 1)
invoked from within
"eval $script"
(procedure "dorunq" line 11)
invoked from within
"dorunq"
("after" script)
This problem has a similar fix to the prior issue: we must use the tlc8
profile when converting this data. Do so, again only on Tcl9 as Tcl8.6
does not recognize -profile, and only Tcl 9.0 makes strict the default.
Signed-off-by: Mark Levedahl <mlevedahl@gmail.com>
gitk invokes many git commands expecting output in utf-8 encoding, but
git accepts extended ascii (code page unknown) as utf-8 without
validating, so cannot guarantee valid utf-8 on output. In particular,
using any extended ascii code page, of which there are many, has long
been acceptable given that everyone on a project is aware of and uses
that same code page to view all data. utf-8 accepts only 7-bit ascii
characters in single bytes, and any characters outside of that base set
require at least two bytes.
Tcl is a string based language, and transcodes all input data to an
internal unicode format, and to whatever format is requested on output:
"pure" binary is recoded using iso8859-1. Tcl8.x silently recodes
invalid utf-8 as binary data, so extended ascii characters maintain
their binary value on output but may not display correctly.
Tcl 8.7 added three profiles to control this behaviour: strict (raises
exceptions), replace (replaces each invalid byte with ?), and the
default tcl8 maintaining the old behavior. Tcl 9 changes the default
profile to strict, meaning any invalid utf-8 raises an exception that
gitk does not handle.
An example of this in the git repository is commit 7eb93c8965 ("[PATCH]
Simplify git script", 2005-09-07). This includes extended ascii
characters in the author name and commit message. As a result, gitk +
Tcl 9 cannot view the git repository at any point beyond that commit.
Note: Tcl 9.0 has a bug, to be fixed in 9.1, where this particular
condition results in a memory error causing Tcl to crash [1].
The tcl8 profile used so far has acceptable behavior given gitk's
acceptance: this allows gitk to accept extended ascii though it may
display incorrectly. Let's continue that behavior by overriding open to
use the tcl8 profile on Tcl9 and later: Tcl 8.6 does not understand
fconfigure -profile, and Tcl 8.7 maintains the tcl8 profile.
