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 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 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.

In an argc/argv pair, the entry for argv[argc] is generally NULL. You
can iterate by counting up to argc, or by looking for the NULL entry in
argv.
When we pass such a pair to setup_revisions(), it shrinks argc to
account for the options we consumed and returns the result to the
caller. But it doesn't touch the entries after the reduced argc. So
argv[argc] will be left pointing at some arbitrary entry rather than
NULL.
This isn't the source of any known bugs, since all callers are aware of
the limitation and act accordingly. But it's a possible gotcha that may
be easy to miss.
Let's set the new argv[argc] to NULL, taking care to free it if the
caller asked us to do so.
It is tempting to do likewise for all of the entries afterwards, too, as
some of them may also need to be freed (e.g., if coming from a strvec).
But doing so isn't entirely trivial, as we munge argc in the function
(e.g., when we find "--" and move all of the entries after it into the
prune_data list). It would be possible with some light refactoring, but
it's probably not worth it. Nobody should ever look at them (they are
beyond the revised argc and past the NULL argv entry) outside of strvec
cleanup, and setup_revisions_from_strvec() already handles this case.
There's one other interesting gotcha: many callers which do not want to
provide arguments just pass 0/NULL for argc/argv. We need to check for
this case before assigning the final NULL.

The previous commit converted callers of setup_revisions() with a strvec
to use the safer and easier _from_strvec() variant.
Let's now convert spots that don't directly have a strvec, but receive
an argc/argv pair that eventually comes from one. We'll instead pass the
strvec down to the point where we call setup_revisions().
That makes these functions slightly less flexible if they were to grow
other callers that don't use strvecs, but this rigidity is buying us
some safety. It is only safe to pass the free_removed_argv_elements
option to setup_revisions() if we know the elements of argv/argc are
allocated on the heap. That isn't communicated in the type system when
we are passed the bare elements. But if we get a strvec, we know that
the elements are allocated strings.
And at any rate, each of these modified functions has only a single
caller (that has a strvec), so the loss of flexibility is unlikely to
ever matter.

Let's now convert spots where we were not setting up the
free_removed_argv_elements flag. As discussed in the previous commit,
this probably isn't fixing any bugs or leaks (since these sites wouldn't

future-proofing us against setup_revisions() becoming more aggressive
about its re-shuffling.

The setup_revisions() function was designed to take the argc/argv pair
from the operating system. But we sometimes construct our own argv using
a strvec and pass that in. There are a few gotchas that callers need to
deal with here:
1. You should always pass the free_removed_argv_elements option via
setup_revision_opt. Otherwise, entries may be leaked if
setup_revisions() re-shuffles options.
2. After setup_revisions() returns, the strvec state is odd. We get a
reduced argc from setup_revisions() telling us how many unknown
options were left in place. Entries after that in argv may be
retained, or may be NULL (depending on how the reshuffling
happened). But the strvec's "nr" field still represents the
original value, and some of the entries it thinks it is still
storing may be NULL. Callers must be careful with how they access
it.
Some callers deal with (1), but not all. In practice they are OK because
they do not pass any options that would cause setup_revisions() to
re-shuffle (namely unknown options which may be relayed from the user,
and the use of the "--" separator). But it's probably a good idea to
consistently pass this option anyway to future-proof ourselves against
the details of setup_revisions() changing.
No callers address (2), though I don't think there any visible bugs.
Most of them simply call strvec_clear() and never otherwise look at the
result. And in fact, if they naively set foo.nr to the argc returned by
setup_revisions(), that would cause leaks! Because setup_revisions()
does not free consumed options[1], we have to leave the "nr" field of
the strvec at its original value to find and free them during
strvec_clear().
So I don't think there are any bugs to fix here, but we can make things
safer and simpler for callers. Let's introduce a helper function that
sets the free_removed_argv_elements automatically and shrinks the strvec
to represent the retained options afterwards (taking care to free the
now-obsolete entries).
We'll start by converting all of the call-sites which use the
free_removed_argv_elements option. There should be no behavior change
for them, except that their "shrunken" entries are cleaned up
immediately, rather than waiting for a strvec_clear() call.
[1] Arguably setup_revisions() should be doing this step for us if we
told it to free removed options, but there are many existing callers
which will be broken if it did. Introducing this helper is a
possible first step towards that.

The setup_revisions() function takes an argc/argv pair and consumes
arguments from it, returning a reduced argc count to the caller. But it
may also overwrite entries within the argv array, as it shifts unknown
options to the front of argv (so they can be found in the range of
0..argc-1 after we return).
For a normal argc/argv coming from the operating system, this is OK.
We don't need to worry about memory ownership of the strings in those
entries. But some callers pass in allocated strings from a strvec, and
we do need to care about those.
We faced a similar issue in f92dbdbc6a (revisions API: don't leak memory
on argv elements that need free()-ing, 2022-08-02), which added an
option for callers to tell us that elements need to be freed. But the
implementation within setup_revisions() was incomplete. It only covered
the case of dropping "--", but not the movement of unknown options.
When we shift argv entries around, we should free the elements we are
about to overwrite, so they are not leaked. For example, in:
git stash show -p --invalid
we will pass this to setup_revisions():
argc = 3, argv[] = { "show", "-p", "--invalid", NULL }
which will then return:
argc = 2, argv[] = { "show", "--invalid", "--invalid", NULL }
overwriting the "-p" entry, which is leaked unless we free it at that
moment.
You can see in the output above another potential problem. We now have
two copies of the "--invalid" string. If the caller does not respect the
new argc when free-ing the strings via strvec_clear(), we'll get a
double-free. And git-stash suffers from this, and will crash with the
above command.
So it seems at first glance that the solution is to just assign the
reduced argc to the strvec.nr field in the caller. Then it would stop
after freeing only any copied entries. But that's not always right
either!
Remember that we are reducing "argc" to account for elements we've
consumed. So if there isn't an invalid option, we'd turn:
argc = 2, argv[] = { "show", "-p", NULL }
into:
argc = 1, argv[] = { "show", "-p", NULL }
In that case strvec_clear() must keep looking past the shortened argc we
return to find the original "-p" to free. It needs to use the original
argc to do that.
We can solve this by turning our argv writes into strict moves, not
copies. When we shuffle an unknown option to the front, we'll overwrite
its old position with NULL. That leaves an argv array that may have NULL
"holes" in it.
So in the "--invalid" example above we get:
argc = 2, argv[] = { "show", "--invalid", NULL, NULL }
but something like "git stash -p --invalid -p" would yield:
argc = 3, argv[] = { "show", "--invalid", NULL, "-p", NULL }
because we move "--invalid" to overwrite the first "-p", but the second
one is quietly consumed. But strvec_clear() can handle that fine (it
iterates over the "nr" field, and passing NULL to free() is OK).
To ease the implementation, I've introduced a helper function. It's a
little hacky because it must take a double-pointer to set the old
position to NULL. Which in turn means we cannot pass "&arg", our local
alias for the current entry we're parsing, but instead "&argv[i]", the
pointer in the original array. And to make it even more confusing, we
delegate some of this work to handle_revision_opt(), which is passed a
subset of the argv array, so is always working on "&argv[0]".
Likewise, because handle_revision_opt() only receives the part of argv
left to parse, it receives the array to accumulate unknown options as a
separate unkc/unkv pair. But we're always working on the same argv
array, so our strategy works fine. I suspect this would be a bit more
obvious (and avoid some pointer cleverness) if all functions saw the
full argv array and worked with positions within it (and our new helper
would take two positions, a src and dst). But that would involve
refactoring handle_revision_opt(). I punted on that, as what's here is
not too ugly and is all contained within revision.c itself.
The new test demonstrates that "git stash show -p --invalid" no longer
crashes with a double-free (because we move instead of copy). And it
passes with SANITIZE=leak because we free "-p" before overwriting.

In "git stash show", we do a first pass of parsing our command line
options by splitting them into revision args and stash args. These are
stored in strvecs, and we pass the revision args to setup_revisions().
But setup_revisions() may modify the argv we pass it, causing us to leak
some of the entries. In particular, if it sees a "--" string, that will
be dropped from argv. This is the same as other cases addressed by
f92dbdbc6a (revisions API: don't leak memory on argv elements that need
free()-ing, 2022-08-02), and we should fix it the same way: by passing
the free_removed_argv_elements option to setup_revisions().
The added test here is run only with SANITIZE=leak, without checking its
output, because the behavior of stash with "--" is a little odd:
1. Running "git stash show" will show --stat output. But running "git
stash show --" will show --patch.
2. I'd expect a non-option after "--" to be treated as a pathspec, so:
git stash show -p 1 -- foo
would look treat "1" as a stash (a synonym for stash@{1}) and
restrict the resulting diff to "foo". But it doesn't. We split the
revision/stash args without any regard to "--". So in the example
above both "1" and "foo" are stashes. Which is an error, but also:
git stash show -- foo
treats "foo" as a stash, not a pathspec.
These are both oddities that we may want to address (or may not, if we
want to retain historical quirks). But they are well outside the scope
of this patch. So for now we'll just let the tests confirm we aren't
leaking without otherwise expecting any behavior. If we later address
either of those points and end up with another test that covers "stash
show --", we can drop this leak-only test.

Right now though we set up the auto-pager, which means that the string
may be written to the pager instead of directly to the terminal. This
behaviour is problematic for two reasons:
- Color codes are meant for direct terminal output; writing them into
a pager does not seem like a sensible thing to do without additional
text.
- It is inconsistent with `git config --get-color`, which never uses a
pager, despite the fact that we claim `git config get --type=color`
to be a drop-in replacement in git-config(1).
Fix this by disabling the pager when outputting color sequences.

Our documentation for git-config(1) has a section where it explains how
to parse and use colors as Git would configure them. In order to get the
ANSI color escape sequence to reset the colors to normal we recommend
the following command:
$ git config get --type=color --default="reset" ""
This command is not supposed to parse any configuration keys. Instead,
it is expected to parse the "reset" default value and turn it into a
proper ANSI color escape sequence.
It was reported though [1] that this command doesn't work:
$ git config get --type=color --default="reset" ""
error: key does not contain a section:
This error was introduced in 4e51389000 (builtin/config: introduce "get"
subcommand, 2024-05-06), where we introduced the "get" subcommand to
retrieve configuration values. The preimage of that commit used `git
config --get-color "" "reset"` instead, which still works.
This use case is really quite specific to parsing colors, as it wouldn't
make sense to give git-config(1) a default value and an empty config key
only to return that default value unmodified. But with `--type=color` we
don't return the value directly; we instead parse the value into an ANSI
escape sequence.
As such, we can easily special-case this one use case:
- If the provided config key is empty;
- the user is asking for a color code; and
- the user has provided a default value,
then we call `get_color()` directly. Do so to make the documented
command work as expected.
