The unsigned long option parsing (including 'k'/'m'/'g' suffix
parsing) is more widely applicable. Add support for OPT_MAGNITUDE
to parse-options.h and change pack-objects.c use this support.
The error behavior on parse errors follows that of OPT_INTEGER. The
name of the option that failed to parse is reported with a brief
message describing the expect format for the option argument and
then the full usage message for the command invoked.
This differs from the previous behavior for OPT_ULONG used in
pack-objects for --max-pack-size and --window-memory which used to
display the value supplied in the error message and did not display
the full usage message.

When for_each_packed_object is called, we call
prepare_packed_git() to make sure we have the actual list of
packs. But the latter does not actually open the pack
indices, meaning that pack->nr_objects may simply be 0 if
the pack has not otherwise been used since the program
started.
In practice, this didn't come up for the current callers,
because they iterate the packed objects only after iterating
all reachable objects (so for it to matter you would have to
have a pack consisting only of unreachable objects). But it
is a dangerous and confusing interface that should be fixed
for future callers.
Note that we do not end the iteration when a pack cannot be
opened, but we do return an error. That lets you complete
the iteration even in actively-repacked repository where an
.idx file may racily go away, but it also lets callers know
that they may not have gotten the complete list (which the
current reachability-check caller does care about).
We have to tweak one of the prune tests due to the changed
return value; an earlier test creates bogus .idx files and
does not clean them up. Having to make this tweak is a good
thing; it means we will not prune in a broken repository,
and the test confirms that we do not negatively impact a
more lenient caller, count-objects.

When no diff nor merge tool is specified (config, option), mergetool-lib
is supposed to choose a default tool from a set of tools. That set is
constructed dynamically depending on the environment (graphical, editor
setting) as a space separated string of tool names.
719518f (mergetool--lib: set IFS for difftool and mergetool, 2015-05-20)
introduced a newline as IFS which breaks the parsing of the space
separated list into items, resulting in a failed search for an available
tool.
Set IFS to a space locally for the tool search.

If tput needs ~/.terminfo for the current $TERM, then tput will
succeed before HOME is changed to $TRASH_DIRECTORY (causing color to
be set to 't') but fail afterward.
One possible way to fix this is to treat HOME like TERM: back up the
original value and temporarily restore it before say_color() runs
tput.
Instead, pre-compute and save the color control sequences before
changing either TERM or HOME. Use the saved control sequences in
say_color() rather than call tput each time. This avoids the need to
back up and restore the TERM and HOME variables, and it avoids the
overhead of a subshell and two invocations of tput per call to
say_color().

This reverts commit 102fc80d32.
There are two issues with that commit:
* It is buggy. In pseudocode, it is doing:
color is set || TERM != dumb && color works && color=t
when it should be doing:
color is set || { TERM != dumb && color works && color=t }
* It unnecessarily disables color when tput needs to read
~/.terminfo to get the control sequences.

"git clean" uses resolve_gitlink_ref() to check for the presence of
nested git repositories, but it has the drawback of creating a
ref_cache entry for every directory that should potentially be
cleaned. The linear search through the ref_cache list causes a massive
performance hit for large number of directories.
Modify clean.c:remove_dirs to use setup.c:is_git_directory and
setup.c:read_gitfile_gently instead.
Both these functions will open files and parse contents when they find
something that looks like a git repository. This is ok from a
performance standpoint since finding repository candidates should be
comparatively rare.
Using is_git_directory and read_gitfile_gently should give a more
standardized check for what is and what isn't a git repository but
also gives three behavioral changes.
The first change is that we will now detect and avoid cleaning empty
nested git repositories (only init run). This is desirable.
Second, we will no longer die when cleaning a file named ".git" with
garbage content (it will be cleaned instead). This is also desirable.
The last change is that we will detect and avoid cleaning empty bare
repositories that have been placed in a directory named ".git". This
is not desirable but should have no real user impact since we already
fail to clean non-empty bare repositories in the same scenario. This
is thus deemed acceptable.
On top of this we add some extra precautions. If read_gitfile_gently
fails to open the git file, read the git file or verify the path in
the git file we assume that the path with the git file is a valid
repository and avoid cleaning.
Update t7300 to reflect these changes in behavior.
The time to clean an untracked directory containing 100000 sub
directories went from 61s to 1.7s after this change.

should be read. Add a sanity check of the file size before opening to

This reverts commit ed178ef13a.
That commit was an attempt to improve the safety of applying
a stash, because the application process may create
conflicted index entries, after which it is hard to restore
the original index state.
Unfortunately, this hurts some common workflows around "git
stash -k", like:
git add -p ;# (1) stage set of proposed changes
git stash -k ;# (2) get rid of everything else
make test ;# (3) make sure proposal is reasonable
git stash apply ;# (4) restore original working tree
If you "git commit" between steps (3) and (4), then this
just works. However, if these steps are part of a pre-commit
hook, you don't have that opportunity (you have to restore
the original state regardless of whether the tests passed or
failed).
It's possible that we could provide better tools for this
sort of workflow. In particular, even before ed178ef, it
could fail with a conflict if there were conflicting hunks
in the working tree and index (since the "stash -k" puts the
index version into the working tree, and we then attempt to
apply the differences between HEAD and the old working tree
on top of that). But the fact remains that people have been
using it happily for a while, and the safety provided by
ed178ef is simply not that great. Let's revert it for now.
In the long run, people can work on improving stash for this
sort of workflow, but the safety tradeoff is not worth it in
the meantime.

An example of the line in a mercurial patch that specifies the date of
the commit would be:
# Date 1433753301 25200
where the first number is the number of seconds since the unix epoch (in
UTC), and the second number is the offset of the timezone, in second s
west of UTC (negative if the timezone is east of UTC).
git-am uses localtime() to break down the first number into its
components (year, month, day, hours, minutes, seconds etc.). However,
the returned components are relative to the user's time zone. As a
result, if the user's time zone does not match the time zone specified
in the patch, the resulting commit will have the wrong author date.
Fix this by using gmtime() instead, which uses UTC instead of the user's
time zone.
