gitexec looks up and caches the method to execute git subcommands using
the long deprecated dashed form if found in $(git--exec-path). But,
git_read and git_write now use the dashless form, by-passing gitexec.
This leaves two remaining uses of gitexec: one during startup to define
use of an ssh_key helper, and one in the about dialog box. These are
neither performance critical nor likely to be called more than once, so
do not justify an otherwise unused cacheing system.
Let's change those two uses, making gitexec unused. This allows removing
gitexec and _git_cmd.

git-gui implements its own approach to locating and running various git
subcommands, bypassing git's capabilities for running git-*. This was
written in 2007: at that time, many git commands were shell-scripts
stored in $(git --exec-path), git's run-command api was not well adapted
to Windows and had serious performance issues when it worked at all, and
running subcommand 'git foo' as 'git-foo' was common and fully supported.
On Windows, git-gui searches $(git --exec-path) for builtin commands,
then attempts to find an interpreter on PATH to run those, invoking
these differently than on other platforms. For instance, the explicit
shebang #!/usr/bin/perl found in a script will be run by the first Perl
interpreter found on $PATH, which might not be at that specific location
so could be different than what git would run.
The various issues leading to the current implemention no longer exist.
Most git commands are now builtins, links to run those are not installed
in $(git --exec-path) by default (the "dashless" form is recommended
instead), and git's run-command api works well everywhere.
So, let's use git to launch its subcommands on all platforms. Do so by
modifying procs git_read and git_write to use the "dashless" form for
invoking git commands, avoiding the search for git-<foo>. This leaves
_git_cmd unused with cleanup in a later patch.

git-gui's default clone method is git-clone's default, and this uses
hardlinks rather than copying the objects directory for local
repositories. However, this method explicitly fails if a symlink (or
.gitfile) exists in the path to the objects directory. Thus, the default
clone option fails for worktrees created by git-new-workdir or
git-worktree. git-gui's original do_clone trapped this error for a
symlinked git-new-workdir tree, directly falling back to a full clone,
while the updated git-gui using git-clone does not. (The old do_clone
could not handle gitfile linked worktrees, however).
Let's apply the more friendly fallback to a full clone in both these
cases where git-clone behavior throws an error on the default method.

git-gui clones a repository by invoking git-plumbing commands, in proc
do_clone, rather than using git-clone. The justification was that the
low-level commands are guaranteed to provide a stable interface, while
the higher level commands such as git-clone may not be stable. This
approach requires git-gui to continually evolve by mirroring new
features in git itself, which has not happened, while the user interface
in git-clone has proven very stable. Also, git-gui does directly call
many other non-plumbing commands in git's repertoire.
do_clone's last significant functionality change was in 2015, and
updates are required for shallow clones, the reftable backend, cloning
from linked worktrees, and perhaps other features and bugs. For
instance, I had reports of git-gui failing to correctly clone
repositories prior to 2015, resulting in essentially the patch given
here. The only significant work was supporting .gitfile linked worktrees
unknown to do_clone, but supported by git-clone, and none regarding the
interface to git-clone itself. That interface is clearly stable enough
to not be a problem.
Supporting new use-cases with this requires exposing new options in the
clone dialog, then passing flags to git-clone. This avoids updating
do_clone to understand those options, reducing the maintenance burdens.
So, teach git-gui to use git-clone. This change is in one patch as
there is no obvious incremental path to migration. The existing dialog /
options / status screen are unchanged, the known user-visible changes
are that cloning from a working directory linked by a gitfile now works,
there is no auto-fallback to a full copy when cloning linked workdirs
and worktrees (meaning git-clone fails unless a full or shared copy is
selected), and messages displayed are from git-clone.

git-gui requires that Tcl and Tk are 8.5, though the check using
'package require' allows 8.6. As git-gui runs under wish, both Tcl and
Tk are always available and of the same version, so only one need be
checked.
The 8.5 requirement is very outdated as the earliest Tcl currently
shipping on any supported OS is 8.6. 8.7 is in alpha test and is
generally compatible with 8.6, so should also be allowed. Tcl 9.0 has
planned compatibility breaking changes so cannot be allowed.
Let's update the requirements to be 8.6 or 8.7, and check only on Tcl as
Tk will be the same version.

gitk commit 5fdcbb1390 ("gitk: Fixes for Mac OS X TkAqua", 2009-03-23),
adds horizontal scrolling of the commit graph pane on aqua, but not on
x11 or win32. Also, the horizontal scrolling is triggered by MouseWheel
events attached to any of the three panes, not just the commit graph
that is the only one that scrolls. It is unusual to scroll a widget that
is not under the mouse, many would consider this a bug. No horizontal
scrollbar is provided for this, so there is no real cue for the user
that horizontal scrolling is available. We removed this aqua only
feature by transitioning aqua to use the common MouseWheel bindings set.
Let's add this as a feature on all platforms, and use the same approach
for scaling scroll motion as we do elsewhere. For horizontal scrolling,
honor only events received by the commit graph in conformance with
normal GUI design. Vertical scrolling is unchanged, and events received
by any of the 3 panes continue to scroll all 3 in unison.
Per the ancient and long ignored CUA standards, we should add a
horizontal scrollbar to the commit-graph, but gitk's interface is
already very cluttered: adding a scrollbar to only one of these three
panes is difficult while maintaining common pane vertical size,
especially so considering the movable sash separating panes 1 & 2, and
will consume yet more space. So, leave this as a hidden feature, now
available on all platforms.

Tk provides MouseWheel events to aqua, similar to win32. But, these
events on aqua have a nominal motion value (%D) of 1, not 120 as on
win32. gitk on aqua provides specific bindings only for the top 3 panes,
giving a nominal scrolling amount of +/- 1 for all events. gitk includes
a hidden feature providing horizontal scrolling of the commit graph,
added in 5fdcbb1390 ("gitk: Fixes for Mac OS X TkAqua", 2009-03-23).
This horizontal scrolling is triggered by mouse events in any of the top
3 panes, and thus violates normal gui design where the object under the
mouse cursor scrolls.
Let's update this using the common bindings in 'proc bind_mousewheel',
allowing user preferences on motion scaling to apply to all windows.
The commit graph scrolling feature is removed by this, and will be added
back for all platforms in a later commit.

gitk has x11 mouse bindings that receive button presses, not MouseWheel
events, as this is the Tk implementation through Tk 8.6. On x11, gitk
translates each button event to a scrolling value of +/- 5 for the upper
three panes that scroll vertically as one unit. gitk applies similar
scaling for horizontal scaling of the lower-left commit details pane
(ctext), but not for vertical scrolling of either of the bottom panes.
Rather, the Tk default scrolling actions are used for vertical
scrolling.
Let's make X11 behave similarly to the just modified win32 platform. Do
so by connecting vertical and horizontal scrolling events for the same
items bound in 'proc bind_mousewheel' and using the same user preference
values.

gitk on win32 binds windows_mousewheel_redirector to all MouseWheel
events in the main window. This proc determines the widget under the
cursor, then determines what scroll command to give, possibly none, and
issues scroll commands to the widget. The top panes get only vertical
scroll events, as does the lower right Patch/Tree pane. All others get
both vertical and horizontal events. These are all hard coded at +/-
five lines.
We now have common MouseWheel event bindings that follow user
preferences for the scrolling amount, bind for only the five main
display widgets, and leave the other gui elements untouched. Let's use
this instead. With the scrolling preference set at 5, the users should
not notice much, if any, difference.

gitk supports scrolling of 5 windows, but does this differently on the
aqua, x11, and win32 platforms as Tk provides different events on each.
TIP 171 removes some differences on win32 while altering the required
bindings on x11. TIP 474, which is in Tk 8.7 and later, finally unifies
all platforms on using common MouseWheel bindings. Importantly for now,
TIP 171 causes delivery of MouseWheel events to the widget under the
mouse cursor on win32, eliminating the need for completely different
bindings on win32.
Let's make some common functions to unify as much as we can in Tk 8.6.
Examining the platforms shows that the default platform scrolling is
overridden differently on the 3 platforms, and the nominal amount of
motion achieved per mouse wheel "click" is different. win32 nominally
makes everything move 5 lines per click, aqua 1 line per click, and x11
is a mixture. Part of this is due to win32 overriding all scroll events,
while x11 and aqua override smaller sets. Also, note that the text
widgets (the lower two panes) always scroll by 2-3 lines when given a
smaller scroll amount, while the upper three canvas objects follow the
requested scrolling value more accurately.
First, let's have a common routine to calculate the scroll value to give
to a widget in an event. This accounts for the user preference, the
scale of the %D (delta) value given by the event (120 on win32, 1 on
aqua, assumed 1 on x11), and must always be integer. Include negation as
by convention the screen moves opposite to the MouseWheel delta. Allow
setting an offset value to account for the larger minimum scrolling of
text widgets.
Second, let's have a common declaration of MouseWheel event bindings, as
those are shared by all in Tcl9, and by aqua/win32 earlier. Bind all
five display windows here. Note that the Patch/Tree widget (cflist)
cannot scroll horizontally.

gitk provides scrolling of several windows, uses hard-coded values for
the amount of scrolling, and these values differ across platforms and
widgets. The nominal value used is either 1 text line per mouse /
touchpad / button event, or 5 lines. Furthermore, Tk does not scroll
text widgets by 1 line when told to, this usually gets 2-3 lines of
motion. The upper canvas objects holding the commit graph do scroll as
defined. But, clearly no value is universally preferred, so let's give
the user some control over this. Provide a single multiplier to be
applied for all scroll bindings, with a value of 3 to mean the default
nominal value of 3 line. This is selected both as a compromise between
the various defaults across platforms, and because it is the smallest
value honored by the two text widgets on the bottom of the screen.
Later commits will connect this variable for actual scrolling events.

Tk through 8.6 has different approaches for handling mouse wheel /
touchpad scrolling events on the different platforms, and gitk has

platform. Let's split these bindings apart.

gitk added the option to used themed Tk (ttk) in 0cc08ff7dd ("gitk: Add

Using ttk had to be optional as Tk 8.4, then in common use, does not
have ttk. ttk is the default when available, so the ttk code paths are
by now very well tested. gitk also has code paths for the older default
widgets, increasing the maintenance burden. Let's make ttk non-optional

gitk includes many user defined configuration variables, has all of
these are listed in $config_variables. But this list is not used to
define the variables to be loaded, saved, or restored when cancelling
the configuration dialog, and developers must maintain separate lists of
variables for these purposes. This leads to unnecessary errors and merge

This patch adds the basic support of SHA256 Git repositories.
Most of changes are idiomatic replacement of the hard-coded hash ID
length, but there are subtle things:
* The hash length is determined on startup, and stored in $hashlength
global variable (either 40 or 64).
* The hard-coded "40" are replaced with $hashlength;
for regexp patterns, the ugly string map is used.
* Some code have the fixed numbers like 39 and 45, and those are
replaced with the $hashlength and the offset correction.
* $nullid and $nullid2 are generated for the hash length.
A caveat is that repository picker dialog is performed before
evaluating the repo type, hence $hashlength isn't set there yet.
So the code dealing with the hard-coded "40" are handled differently;
namely, the regexp range is expanded, and the null id is generated
from the HEAD id length locally.

To enable optimize multiple pathspec items in revision traversal,
return 0 if all pathspec item is literal in forbid_bloom_filters().
Add for loops to initialize and check each pathspec item's bloom_keyvec
when optimization is possible.
Add new test cases in t/t4216-log-bloom.sh to ensure
- consistent results between the optimization for multiple pathspec
items using bloom filter and the case without bloom filter
optimization.
- does not use bloom filter if any pathspec item is not literal.
With these optimizations, we get some improvements for multi-pathspec runs
of 'git log'. First, in the Git repository we see these modest results:
Benchmark 1: old
Time (mean ± σ): 73.1 ms ± 2.9 ms
Range (min … max): 69.9 ms … 84.5 ms 42 runs
Benchmark 2: new

Range (min … max): 51.1 ms … 61.2 ms 52 runs
Summary
'new' ran
1.33 ± 0.09 times faster than 'old'
But in a larger repo, such as the LLVM project repo below, we get even
better results:
