git-gui currently runs some hooks directly using its own code written
before 2010, long predating git v2.9 that added the core.hooksPath
configuration to override the assumed location at $GIT_DIR/hooks. Thus,
git-gui looks for and runs hooks including prepare-commit-msg,
commit-msg, pre-commit, post-commit, and post-checkout from
$GIT_DIR/hooks, regardless of configuration. Commands (e.g., git-merge)
that git-gui invokes directly do honor core.hooksPath, meaning the
overall behaviour is inconsistent.
Furthermore, since v2.36 git exposes its hook execution machinery via
`git-hook run`, eliminating the need for others to maintain code
duplicating that functionality. Using git-hook will both fix git-gui's
current issues on hook configuration and (presumably) reduce the
maintenance burden going forward. So, teach git-gui to use git-hook.

Earlier, commit aae9560a introduced search in $PATH to find executables
before running them, avoiding an issue where on Windows a same named
file in the current directory can be executed in preference to anything
in a directory in $PATH. This search is intended to find an absolute
path for a bare executable ( e.g, a function "foo") by finding the first
instance of "foo" in a directory given in $PATH, and this search works
correctly. The search is explicitly avoided for an executable named
with an absolute path (e.g., /bin/sh), and that works as well.
Unfortunately, the search is also applied to commands named with a
relative path. A hook script (or executable) $HOOK is usually located
relative to the project directory as .git/hooks/$HOOK. The search for
this will generally fail as that relative path will (probably) not exist
on any directory in $PATH. This means that git hooks in general now fail
to run. Considerable mayhem could occur should a directory on $PATH be
git controlled. If such a directory includes .git/hooks/$HOOK, that
repository's $HOOK will be substituted for the one in the current
project, with unknown consequences.
This lookup failure also occurs in worktrees linked to a remote .git
directory using git-new-workdir. However, a worktree using a .git file
pointing to a separate git directory apparently avoids this: in that
case the hook command is resolved to an absolute path before being
passed down to the code introduced in aae9560a.
Fix this by replacing the test for an "absolute" pathname to a check for
a command name having more than one pathname component. This limits the
search and absolute pathname resolution to bare commands. The new test
uses tcl's "file split" command. Experiments on Linux and Windows, using
tclsh, show that command names with relative and absolute paths always
give at least two components, while a bare command gives only one.
Linux: puts [file split {foo}] ==> foo
Linux: puts [file split {/foo}] ==> / foo
Linux: puts [file split {.git/foo}] ==> .git foo
Windows: puts [file split {foo}] ==> foo
Windows: puts [file split {c:\foo}] ==> c:/ foo
Windows: puts [file split {.git\foo}] ==> .git foo
The above results show the new test limits search and replacement
to bare commands on both Linux and Windows.

git-gui enables the "Repository->Explore Working Copy" menu on Cygwin,
offering to open a Windows graphical file browser at the root of the
working directory. This code, shared with Git For Windows support,
depends upon use of Windows pathnames. However, git gui on Cygwin uses
unix pathnames, so this shared code will not work on Cygwin.
A base install of Cygwin provides the /bin/cygstart utility that runs
a registered Windows application based upon the file type, after
translating unix pathnames to Windows. Adding the --explore option
guarantees that the Windows file explorer is opened, regardless of the
supplied pathname's file type and avoiding possibility of some other
action being taken.
So, teach git-gui to use cygstart --explore on Cygwin, restoring the
pre-2012 behavior of opening a Windows file explorer for browsing. This
separates the Git For Windows and Cygwin code paths. Note that
is_Windows is never true on Cygwin, and is_Cygwin is never true on Git
for Windows, though this is not obvious by examining the code for those
independent functions.

In the current git release, git-gui runs on Cygwin without enabling any
of git-gui's Cygwin specific code. This happens as the Cygwin specific
code in git-gui was (mostly) written in 2007-2008 to work with Cygwin's
then supplied Tcl/Tk which was an incompletely ported variant of the
8.4.1 Windows Tcl/Tk code. In March, 2012, that 8.4.1 package was
replaced with a full port based upon the upstream unix/X11 code,
since maintained up to date. The two Tcl/Tk packages are completely
incompatible, and have different signatures.
When Cygwin's Tcl/Tk signature changed in 2012, git-gui no longer
detected Cygwin, so did not enable Cygwin specific code, and the POSIX
environment provided by Cygwin since 2012 supported git-gui as a generic
unix. Thus, no-one apparently noticed the existence of incompatible
Cygwin specific code.
However, since commit c5766eae6f in the git-gui source tree
(https://github.com/prati0100/git-gui, master at a5005ded), and not yet
pulled into the git repository, the is_Cygwin function does detect
Cygwin using the unix/X11 Tcl/Tk. The Cygwin specific code is enabled,
causing use of Windows rather than unix pathnames, and enabling
incorrect warnings about environment variables that were relevant only
to the old Tcl/Tk. The end result is that (upstream) git-gui is now
incompatible with Cygwin.
So, delete Cygwin specific code (code protected by "if is_Cygwin") that
is not needed in any form to work with the unix/X11 Tcl/Tk.
Cygwin specific code required to enable file browsing and shortcut
creation is not addressed in this patch, does not currently work, and
invocation of those items may leave git-gui in a confused state.

As per https://www.tcl.tk/man/tcl8.6/TclCmd/exec.html#M23, Tcl's `exec`
function goes out of its way to imitate the highly dangerous path lookup
of `cmd.exe`, but _of course_ only on Windows:
If a directory name was not specified as part of the application
name, the following directories are automatically searched in
order when attempting to locate the application:
The directory from which the Tcl executable was loaded.
The current directory.
The Windows 32-bit system directory.
The Windows home directory.
The directories listed in the path.
The dangerous part is the second item, of course: `exec` _prefers_
executables in the current directory to those that are actually in the
`PATH`.
It is almost as if people wanted to Windows users vulnerable,
specifically.
To avoid that, Git GUI already has the `_which` function that does not
imitate that dangerous practice when looking up executables in the
search path.
However, Git GUI currently fails to use that function e.g. when trying to
execute `aspell` for spell checking.
That is not only dangerous but combined with Tcl's unfortunate default
behavior and with the fact that Git GUI tries to spell-check a
repository just after cloning, leads to a critical Remote Code Execution
vulnerability.
Let's override both `exec` and `open` to always use `_which` instead of
letting Tcl perform the path lookup, to prevent this attack vector.
This addresses CVE-2022-41953.

The `is_Cygwin` function is used, among other things, to determine
how executables are discovered in the `PATH` list by the `_which` function.
We are about to change the behavior of the `_which` function on Windows
(but not Cygwin): On Windows, we want it to ignore empty elements of the
`PATH` instead of treating them as referring to the current directory
(which is a "legacy feature" according to
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_03,
but apparently not explicitly deprecated, the POSIX documentation is
quite unclear on that even if the Cygwin project itself considers it to
be deprecated: https://github.com/cygwin/cygwin/commit/fc74dbf22f5c).
This is important because on Windows, `exec` does something very unsafe
by default (unless we're running a Cygwin version of Tcl, which follows
Unix semantics).
However, we try to `exec` something _inside_ `is_Cygwin` to determine
whether we're running within Cygwin or not, i.e. before we determined
whether we need to handle `PATH` specially or not. That's a Catch-22.
Therefore, and because it is much cleaner anyway, use the
`$::tcl_platform(os)` value which is guaranteed to start with `CYGWIN_`
when running a Cygwin variant of Tcl/Tk, instead of executing `cygpath
--windir`.

When looking up an executable via the `_which` function, Git GUI
imitates the `execlp()` strategy where the environment variable `PATH`
is interpreted as a list of paths in which to search.
For historical reasons, stemming from the olden times when it was
uncommon to download a lot of files from the internet into the current
directory, empty elements in this list are treated as if the current
directory had been specified.
Nowadays, of course, this treatment is highly dangerous as the current
directory often contains files that have just been downloaded and not
yet been inspected by the user. Unix/Linux users are essentially
expected to be very, very careful to simply not add empty `PATH`
elements, i.e. not to make use of that feature.
On Windows, however, it is quite common for `PATH` to contain empty
elements by mistake, e.g. as an unintended left-over entry when an
application was installed from the Windows Store and then uninstalled
manually.
While it would probably make most sense to safe-guard not only Windows
users, it seems to be common practice to ignore these empty `PATH`
elements _only_ on Windows, but not on other platforms.
Sadly, this practice is followed inconsistently between different
software projects, where projects with few, if any, Windows-based
contributors tend to be less consistent or even "blissful" about it.
Here is a non-exhaustive list:
Cygwin:
It specifically "eats" empty paths when converting path lists to
POSIX: https://github.com/cygwin/cygwin/commit/753702223c7d
I.e. it follows the common practice.
PowerShell:
It specifically ignores empty paths when searching the `PATH`.
The reason for this is apparently so self-evident that it is not
even mentioned here:
https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_environment_variables#path-information
I.e. it follows the common practice.
CMD:
Oh my, CMD. Let's just forget about it, nobody in their right
(security) mind takes CMD as inspiration. It is so unsafe by
default that we even planned on dropping `Git CMD` from Git for
Windows altogether, and only walked back on that plan when we
found a super ugly hack, just to keep Git's users secure by
default:
https://github.com/git-for-windows/MINGW-packages/commit/82172388bb51
So CMD chooses to hide behind the battle cry "Works as
Designed!" that all too often leaves users vulnerable. CMD is
probably the most prominent project whose lead you want to avoid
following in matters of security.
Win32 API (`CreateProcess()`)
Just like CMD, `CreateProcess()` adheres to the original design
of the path lookup in the name of backward compatibility (see
https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-createprocessw
for details):
If the file name does not contain a directory path, the
system searches for the executable file in the following
sequence:
1. The directory from which the application loaded.
2. The current directory for the parent process.
[...]
I.e. the Win32 API itself chooses backwards compatibility over
users' safety.
Git LFS:
There have been not one, not two, but three security advisories
about Git LFS executing executables from the current directory by
mistake. As part of one of them, a change was introduced to stop
treating empty `PATH` elements as equivalent to `.`:
https://github.com/git-lfs/git-lfs/commit/7cd7bb0a1f0d
I.e. it follows the common practice.
Go:
Go does not follow the common practice, and you can think about
that what you want:
https://github.com/golang/go/blob/go1.19.3/src/os/exec/lp_windows.go#L114-L135https://github.com/golang/go/blob/go1.19.3/src/path/filepath/path_windows.go#L108-L137
Git Credential Manager:
It tries to imitate Git LFS, but unfortunately misses the empty
`PATH` element handling. As of time of writing, this is in the
process of being fixed:
https://github.com/GitCredentialManager/git-credential-manager/pull/968
So now that we have established that it is a common practice to ignore
empty `PATH` elements on Windows, let's assess this commit's change
using Schneier's Five-Step Process
(https://www.schneier.com/crypto-gram/archives/2002/0415.html#1):
Step 1: What problem does it solve?
It prevents an entire class of Remote Code Execution exploits via
Git GUI's `Clone` functionality.
Step 2: How well does it solve that problem?
Very well. It prevents the attack vector of luring an unsuspecting
victim into cloning an executable into the worktree root directory
that Git GUI immediately executes.
Step 3: What other security problems does it cause?
Maybe non-security problems: If a project (ab-)uses the unsafe
`PATH` lookup. That would not only be unsafe, though, but
fragile in the first place because it would break when running
in a subdirectory. Therefore I would consider this a scenario
not worth keeping working.
Step 4: What are the costs of this measure?
Almost nil, except for the time writing up this commit message
;-)
Step 5: Given the answers to steps two through four, is the security
measure worth the costs?
Yes. Keeping Git's users Secure By Default is worth it. It's a
tiny price to pay compared to the damages even a single
successful exploit can cost.
So let's follow that common practice in Git GUI, too.

In 4e55d19 (git-gui: Cleanup end-of-line whitespace in commit messages.,
2007-01-25), the logic to decide if GITGUI_MSG should be saved or
deleted was updated to not require the commit message buffer to be
modified. This fixes a situation where if the user quits and restarts
git-gui multiple times the commit message buffer was lost.
Unfortunately, the fix was not quite correct. The check for whether the
commit message buffer has been modified is useless. If the commit is
_not_ amend, then the check is never performed. If the commit is amend,
then saving the message does not matter anyway. Amend state is destroyed
on exit and the next time git-gui is opened it starts from scratch, but
with the older message retained in the buffer. If amend is selected,
the current message is over-written by the amend commit's message.
The correct fix would be to not touch GITGUI_MSG at all if the commit
message buffer is not modified. This way, the file is not deleted even
on multiple restarts. It has the added benefit of not writing the file
unnecessarily on every exit.

For some asynchronous operations, we build a chain of callbacks to
execute when the operation is done. These callbacks are held in $after,
and a new callback can be added by appending to $after. Once the
operation is done, $after is executed as a script.
But if we don't append a semi-colon after the procedure calls, they will
appear to Tcl as arguments to the previous procedure's arguments. So,
for example, if $after is "foo", and we just append "bar", then $after
becomes "foo bar", and bar will be treated as an argument to foo. If foo
does not accept any optional arguments, it would result in Tcl throwing
an error. If instead we do append a semi-colon, $after will look like
"foo;bar;", and these will be treated as two separate procedure calls.
Before d9c6469 (git-gui: update status bar to track operations,
2019-12-01), this problem was masked because ui_ready/ui_status did
accept an optional argument. In d9c6469, ui_ready stopped accepting an
optional argument, and this error started showing up.
Another instance of this problem is when a call to ui_status without a
trailing semicolon. ui_status never accepted an optional argument to
begin with, but the issue never managed to surface.
So, fix these errors by making sure we always append a semi-colon after
procedure calls when multiple callbacks are involved in $after.

* py/remove-tcloo:
git-gui: create a new namespace for chord script evaluation
git-gui: reduce Tcl version requirement from 8.6 to 8.5
On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.
The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.
This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.
As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up
shouting that their OS ships with 8.4 only. Then we would have to look
into implementing it in pure Tcl.

In d9c6469 (git-gui: update status bar to track operations, 2019-12-01)
the call to 'ui_status' in 'do_gitk' was updated to create the newly
introduced "status bar operation". This allowed this status text to show
along with other operations happening in parallel, and removed a race
between all these operations.
But in that refactor, the fact that 'ui_status' checks for the existence
of 'main_status' was overlooked. This leads to an error message popping
up when the user selects "Show History Context" from the blame window
context menu on a source line. The error occurs because when running
"blame" 'main_status' is not initialized.
So, add a check for the existence of 'main_status' in 'do_gitk'. This
fix reverts to the original behaviour. In the future, we might want to
look into a better way of telling 'do_gitk' which status bar to use.

The user cannot change focus between the list of files, the diff view and
the commit message widgets without using the mouse (clicking either of
the four widgets).
With this patch, the user may set ui focus to the previously selected path
in either the "Unstaged Changes" or "Staged Changes" widgets, using
ALT+1 or ALT+2.
The user may also set the ui focus to the diff view widget with
ALT+3, or to the commit message widget with ALT+4.
This enables the user to select/unselect files, view the diff and create a
commit in git-gui using keyboard-only.

Accidental clicks on the revert hunk/lines buttons can cause loss of
work, and can be frustrating. So, allow undoing the last revert.
Right now, a stack or deque are not being used for the sake of
simplicity, so only one undo is possible. Any reverts before the
previous one are lost.

Just like the user can select lines to stage or unstage, add the
ability to revert selected lines.

If the toplevel window for the window being destroyed is the main window
(aka "."), then simply destroying it means the cleanup tasks are not
executed (like saving the commit message buffer, saving window state,
etc.)
All this is handled by do_quit. Call it instead of directly
destroying the main window. For other toplevel windows, the old
behavior remains.

CTRL/CMD+ENTER is bound to do_commit, but this did not apply for the
(numpad ENTER) key. To enable CTRL/CMD+ENTER and CTRL/CMD+(numpad ENTER)
to yield the same behaviour, CTRL/CMD+(numpad enter) has also been bound
to do_commit.

It is possible to select multiple files in the "Unstaged Changes" and
the "Staged Changes" lists. But when hitting Ctrl+T, surprisingly only
one entry is handled, not all selected ones.
Let's just use the same code path as for the "Stage To Commit" and the
"Unstage From Commit" menu items.

If there is nothing to stage, there is nothing to stage. Let's not try
to, even if the file list contains nothing at all.

Previously unstaged files can be staged by clicking on them and then
pressing Ctrl+T. Conveniently, the next unstaged file is selected
automatically so that the unstaged files can be staged by repeatedly
pressing Ctrl+T.
When a user hits Ctrl+T one time too many, though, Git GUI used to throw
this exception:
expected number but got ""
expected number but got ""
while executing
"expr {int([lindex [$w tag ranges in_diff] 0])}"
(procedure "toggle_or_diff" line 13)
invoked from within
"toggle_or_diff toggle .vpane.files.workdir.list "
(command bound to event)
Let's just avoid that by skipping the operation when there are no more
files to stage.

The mailing address for the FSF has changed over the years. Rather than
updating the address across all files, refer readers to gnu.org, as the
GNU GPL documentation now suggests for license notices. The mailing
address is retained in the full license files (COPYING and LGPL-2.1).

If we use 'eval exec $opt $cmdp $args' to execute git command,
tcl engine will convert the output of the git comand with the rule
system default code page to unicode.
But cp936 -> unicode conversion implicitly done by exec is not reversible.
So we have to use git_read instead.

Assumes file names in git tree objects are UTF-8 encoded.
On most unix systems, the system encoding (and thus the TCL system
encoding) will be UTF-8, so file names will be displayed correctly.
On Windows, it is impossible to set the system encoding to UTF-8. Changing
the TCL system encoding (via 'encoding system ...', e.g. in the startup
code) is explicitly discouraged by the TCL docs.
Change git-gui functions dealing with file names to always convert
from and to UTF-8.
