In early days, all projects managed by git (except for git itself) had the
product of a fairly mature development history in their first commit, and
it was deemed unnecessary clutter to show additions of these thousands of
paths as a patch.

"git log" learned to show the patch for the initial commit without requiring
--root command line option at 0f03ca94 (config option log.showroot to show
the diff of root commits, 2006-11-23).

Teach gitk to respect log.showroot.

Sometimes one wants to see the different between two commits that are
a long distance apart in the graph display.  This is difficult to do
with the "Diff this -> selected" and "Diff selected -> this" menu
items because the need to maintain the selection means that one can't
use the find facilities or the reference list window to navigate from
one to the other.

This provides an alternative using the mark.  Having found one commit,
one marks it with the "Mark this commit" menu item, then navigates to
the other commit and uses the new "Diff this -> marked commit" and/or
"Diff marked commit -> this" menu items.

On large repositories such as the Linux kernel, it can take quite a
noticeable time (several seconds) for gitk to resolve short SHA1 IDs
to their long form.  This speeds up the process by maintaining lists
of IDs indexed by the first 4 characters of the SHA1 ID, speeding up
the search by a factor of 65536 on large repositories.

The following only concerns systems using X and the client-side font
rendering framework from freedesktop.org.  Windows and Mac OS X are
not affected.

Starting with version 8.5, Tk uses freetype and fontconfig by default
to render fonts on platforms that support it.  Gitk currently defaults
to the font Helvetica for the interface and Courier for diffs, and
both unfortunately look rather bad on screen in the default
configuration on many Linux distros with anti-aliasing and poor
hinting.

It is better to default to "sans" and "monospace", which are mapped by
fontconfig to some appropriate font of the sysadmin and user's
choosing (typically Bitstream Vera Sans and Mono).  The result looks
more sensible and it makes gitk feel like a well-behaved software
citizen since its fonts match other native apps.

This patch does not change the appearance of gitk for users that have
already run it, since gitk uses the remembered UI and diff font names
from ~/.gitk.

Automake's contribution guidelines suggest using "git describe" output
in commit logs to reference previous commits.  By contrast, in
coreutils, I had acquired the habit of using a bare SHA1 prefix (8 hex
digits), since gitk creates clickable links for that, and not for "git
describe" output.

I prefer the readability of the full "git describe" output, yet want
to retain the gitk links, so this renders as clickable not just
SHA1-like strings, but also an SHA1-like string that is prefixed by
"-g".

Launching 'gitk -- .' or 'gitk -- ..\t' restricts the display to files
under the given directory but the file list is left empty. This is because
the path_filter function fails to match the filenames which are relative
to the working tree to the filter which is filessytem relative.
This solves the problem by making both names fully qualified filesystem
paths before performing the comparison.

When commit 6e2dda35 (Add new keybindings, 2005-09-22) added vi-style
keybindings to gitk (an excellent idea!), instead of adopting the
usual "hjkl = left, down, up, right" bindings used by less, vi, rogue,
and many other programs, it used "ijkl = up, left, down, right" to
mimic the inverted-T formation of the arrow keys on a qwerty keyboard,
in the style of Lode runner.  So using 'j' and 'k' to scroll through
commits produces utterly confusing results to the vi user, as 'k'
moves down and 'j' moves to the previous commit.

Luckily most non-vi-users are probably using an alternate set of keys
(cursor keys or z/x + n/p) anyway.  Switch to the expected vi/nethack
convention.

Gitk can search for commits touching a specified path. The search text is
always treated as a regular expression, regardless of the matching option
selected (Exact, IgnCase, or Regexp). In particular, backslashes escape
the next character. This is inconvenient on Windows systems, where backslashes
are the norm for path specifiers, for example when copy/pasting from
Windows Explorer or a cmd shell -- these copy-pasted paths must be manually
modified in the gitk search text edit box before they will work.

This change uses the match option "Exact" to mean that a slash is a slash,
not part of a regular expression. Backslashes are converted to frontslashes
before searching, thus allowing easy copy/pasting of paths on Windows
systems. If the previous behaviour of "touching paths" search is desired,
simply select the "Regexp" search mode.

One potential drawback is that the default setting for the match option
($findtype in the code) is "Exact", and so this change alters the default
behaviour, which may confuse users and lead to bug reports.

Since 5024baa4 ([PATCH] Make gitk work when launched in a subdirectory,
2007-01-09), gitk has used 'git rev-parse --git-dir' to find the .git
directory. However, gitk still first checks for the $GIT_DIR
environment variable and that the value returned from git-rev-parse
does not point to a file. Since git-rev-parse does both of these
checks already, the checks can safely be removed from gitk. This makes
the gitdir procedure small enough to inline.

This cleanup introduces a UI regression in that the error message will
now be "Cannot find a git repository here." even in the case where
GIT_DIR points to a file, for which the error message was previously
"Cannot find the git directory \"%s\".". It should be noted, though,
that even before this patch, 'gitk --git-dir=path/to/some/file' would
give the former error message.

When running "External diff" from gitk, the "from" and "to" files will
first be copied into a directory that is currently
".git/../.gitk-tmp.$pid".  When gitk is closed, the directory is
deleted. When the work tree is not at ".git/.." (which is supported
since the previous commit), that directory may not even be git-related
and it does not seem unlikely that permissions may not allow the
temporary directory to be created there.  Move the directory inside

The "highlight this only" and "highlight this too" commands in gitk
add the path relative to $GIT_WORK_TREE to the "Find" input box. When
the search (using git-diff-tree) is run, the paths are used
unmodified, except for some shell escaping. Since the search is run
from gitk's working directory, no commits matching the paths will be
found if gitk was started in a subdirectory.

Make the paths passed to git-diff-tree relative to gitk's working
directory instead of being relative to $GIT_WORK_TREE. If, however,
gitk is run outside of the working directory (e.g. with $GIT_WORK_TREE
set), we still need to use the path relative to $GIT_WORK_TREE.

Stolen from git-gui, 23effa79 (original log message by

    Apparently a "feature" of Tcl/Tk on Mac OS X is that a disabled text

    makes the diff viewer almost useless on that platform as you cannot
    select individual parts of the buffer.

    Now we force focus into the diff viewer when its clicked on with

Starting from ~ git-1.6.6, log, show & whatchanged show notes by default.

On the other hand, gitk does not show notes by default, because under
the hood it calls 'git log --pretty=raw ...' to get the log, and in
'git log' notes are turned off when user specifies format or pretty
settings.

Yes, it is possible to invoke 'gitk --show-notes' explicitly, but since
from user's perspective, gitk is gui enabled git log, it would be
logical for gitk to show notes by default too for consistency.

In git, --show-notes was introduced in 66b2ed (Fix "log" family not to
be too agressive about showing notes) which predates 1.6.6.2.

Notes can still be supressed with 'gitk --no-notes'.
