We started using "%" PRItime, imitating "%" PRIuMAX and friends, as
a way to format the internal timestamp value, but this does not
play well with gettext(1) i18n framework, and causes "make pot"
that is run by the l10n coordinator to create a broken po/git.pot
file. This is a possible workaround for that problem.

We started using our own timestamp_t type and PRItime format
specifier to go along with it, so that we can later change the
underlying type and output format more easily, but this does not
play well with gettext tools.
Because gettext tools need to keep the *.po file portable across
platforms, they have to special-case the format specifiers like
PRIuMAX that are known types in inttypes.h, instead of letting CPP
handle strings like
"%" PRIuMAX " seconds ago"
as an ordinary string concatenation. They fundamentally cannot do
the same for our own custom type/format.
Given that po/git.pot needs to be generated only once every release
and by only one person, i.e. the l10n coordinator, let's update the
Makefile rule to generate po/git.pot so that gettext tools are run
on a munged set of sources in which all mentions of PRItime are
replaced with PRIuMAX, which is what we happen to use right now.
This way, developers do not have to care that PRItime does not play
well with gettext, and translators do not have to care that we use
our own PRItime.
The credit for the idea to munge the source files goes to Dscho.
Possible bugs are mine.

The paragraph that describes the 'scissors' cleanup mode of
'commit' had the 'cut-line' in the middle of a sentence. This
made it possible for the line to get wrapped on smaler windows.
This shouldn't be the case as it makes it hard for the user to
understand the structure of the cut-line.
Reformat the pragraph to make the 'cut-line' stand on a line of
it's own thus distinguishing it from the rest of the paragraph.
This further prevents it from getting wrapped to some extent.

We run an early part of "git gc" that deals with refs before
daemonising (and not under lock) even when running a background
auto-gc, which caused multiple gc processes attempting to run the
early part at the same time. This is now prevented by running the

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.

The i18n config variable used weren't readable as they were in

The test_copy_bytes() function claims to read up to N bytes,

It is totally legitimate to add CamelCased aliases, but due to the way
config keys are compared, the case does not matter.
Therefore, we must compare the alias name insensitively to the config
keys.

the early config machinery to expand aliases, 2017-06-14).

The option -G of p4 (python marshal output) gives more context about the
data being output. That's useful when using the command "change -o" as
we can distinguish between warning/error line and real change description.

Some p4 triggers in the server side generate some warnings when

p4 commands. A few git-p4 commands don't expect extra messages or output
lines and may fail with verbose triggers.

We normally try to avoid having two auto-gc operations run
at the same time, because it wastes resources. This was done
long ago in 64a99eb47 (gc: reject if another gc is running,
unless --force is given, 2013-08-08).
When we do a detached auto-gc, we run the ref-related
commands _before_ detaching, to avoid confusing lock
contention. This was done by 62aad1849 (gc --auto: do not
lock refs in the background, 2014-05-25).
These two features do not interact well. The pre-detach
operations are run before we check the gc.pid lock, meaning
that on a busy repository we may run many of them
concurrently. Ideally we'd take the lock before spawning any
operations, and hold it for the duration of the program.
This is tricky, though, with the way the pid-file interacts
with the daemonize() process. Other processes will check
that the pid recorded in the pid-file still exists. But
detaching causes us to fork and continue running under a
new pid. So if we take the lock before detaching, the
pid-file will have a bogus pid in it. We'd have to go back
and update it with the new pid after detaching. We'd also
have to play some tricks with the tempfile subsystem to
tweak the "owner" field, so that the parent process does not
clean it up on exit, but the child process does.
Instead, we can do something a bit simpler: take the lock
only for the duration of the pre-detach work, then detach,
then take it again for the post-detach work. Technically,
this means that the post-detach lock could lose to another
process doing pre-detach work. But in the long run this
works out.
That second process would then follow-up by doing
post-detach work. Unless it was in turn blocked by a third
process doing pre-detach work, and so on. This could in
theory go on indefinitely, as the pre-detach work does not
repack, and so need_to_gc() will continue to trigger. But
in each round we are racing between the pre- and post-detach
locks. Eventually, one of the post-detach locks will win the
race and complete the full gc. So in the worst case, we may
racily repeat the pre-detach work, but we would never do so
simultaneously (it would happen via a sequence of serialized
race-wins).
