The normal way to check whether a certain revision resolves to a valid
commit is:
$ git rev-parse --verify $REV^0
Unfortunately, this does not work when $REV is of the type :/quuxery.

git-remote-mediawiki: brace file handles for print for more clarity
This follows the following rule:
InputOutput::RequireBracedFileHandleWithPrint (Severity: 1)
The `print' and `printf' functions have a unique syntax that supports an
optional file handle argument. Conway suggests wrapping this argument in
braces to make it visually stand out from the other arguments. When you
put braces around any of the special package-level file handles like
`STDOUT', `STDERR', and `DATA', you must the `'*'' sigil or else it
won't compile under `use strict 'subs''.

changing split(' ') to split(/ /) could potentially be a regression, however,

Perl's split function takes a regex pattern argument. You can also
feed it an expression, which is then compiled into a regex at runtime.
It therefore works to pass your pattern via single quotes, but it is
much less obvious to a reader that the argument is meant to be a
regex, not a static string. Using the traditional slash-delimiters

This is because "git ls-files" is used to find which paths are bound to

The compiler can short-circuit the evaluation of conditions strung

intent of the changed code clearer, because the logical context (as
opposed to binary context) becomes immediately obvious.

This is a pure code movement of the machinery for copying notes to

it was declared in builtin.h. This was more of an accident of history
than a concious design, and we now want to make this machinery more
widely available.
Hence, this patch moves the code into the new notes-utils.[hc] files

Primarily to push out two regression issues that seem to affect many
people, namely, the ".gitignore !directory" bug and "daemon cannot
read from $HOME owned by root" bug.
Most users seem to like having colors enabled, and colors can help
beginners to understand the output of some commands (e.g. notice
immediately the boundary between commits in the output of "git log").
Many tutorials tell the users to set color.ui=auto as a very first step,
which tend to indicate that color.ui=none is not the recommanded value,
hence should not be the default.
These tutorials would benefit from skipping this step and starting the
real Git manipulations earlier. Other beginners do not know about
color.ui=auto, and may not discover it by themselves, hence live with
black&white outputs while they may have preferred colors.
A few people (e.g. color-blind) prefer having no colors, but they can
easily set color.ui=never for this (and googling "disable colors in git"
already tells them how to do so), but this needs not occupy space in
beginner-oriented documentations.
A transition period with Git emitting a warning when color.ui is unset
would be possible, but the discomfort of having the warning seems
superior to the benefit: users may be surprised by the change, but not
harmed by it.
The default value is changed, and the documentation is reworded to
mention "color.ui=false" first, since the primary use of color.ui after
this change is to disable colors, not to enable it.

discard_cache doesn't have to free the array of cache entries, because
the next call of read_cache can simply reuse it, as they all operate on
the global variable the_index.
discard_index on the other hand does have to free it, because it can be
used e.g. with index_state variables on the stack, in which case a
missing free would cause an unrecoverable leak. This patch releases the
memory and removes a comment that was relevant for discard_cache but has
become outdated.
Since discard_cache is just a wrapper around discard_index nowadays, we
lose the optimization that avoids reallocation of that array within
loops of read_cache and discard_cache. That doesn't cause a performance
regression for me, however (HEAD = this patch, HEAD^ = master + p0002):

The 'git show' completion uses __git_complete_file (aliased to

in A..B notation, so using __git_complete_revlist_file is more
appropriate.
There still remain two users of __git_complete_file, completions for

Commit e3d06ca (git-gui: Detect full path when parsing arguments -
2012-10-02) fixed the handling of absolute paths passed to the browser
and blame subcommands by checking whether the file exists without the
prefix before prepending the prefix and checking again. Since we have
chdir'd to the top level of the working tree before doing this, this
does not work if a file with the same name exists in a subdirectory and
at the top level (for example Makefile in git.git's t/ directory).
Instead of doing this, revert that patch and fix absolute path issue by
using "file join" to prepend the prefix to the supplied path. This will
correctly handle absolute paths by skipping the prefix in that case.
