When grep is called with the --quiet option, the pager is initialized
despite not being used. When the pager is "less", anything output by
previous commands and not ended with a newline is overwritten:
$ echo -n aaa; echo bbb
aaabbb
$ echo -n aaa; git grep -q foo; echo bbb
bbb
This can be worked around, for example, by making sure STDOUT is not a
TTY or more directly by setting git's pager to "cat":
$ echo -n aaa; git grep -q foo > /dev/null; echo bbb
aaabbb
$ echo -n aaa; PAGER=cat git grep -q foo; echo bbb
aaabbb
But prevent calling the pager in the first place, which would also
save an unnecessary fork().

Because "--graph" is about connected history while --no-walk is
about discrete points, it does not make sense to allow these two
options at the same time. [1]
This change makes a few calls to "show --graph" fail in t4052, but
asking to show one commit with graph is a nonsensical thing to do.
Thus, tests on "show --graph" in t4052 have been removed [2,3].
Same tests on "show" without --graph option have already been tested
in 4052.
3 testcases have been added to test this patch.

"git rebase -i" recently started to include the number of

xgettext sees "% o" and interprets it as a placeholder for an octal
number preceded by a space. However, in this case it's not actually a
placeholder, and most translations will replace the "% o" sequence with
something else. Removing the tcl-format flag from this string prevents
tools like Poedit from freaking out when "% o" doesn't appear in the
translated string.
The corrected flag will appear in each translation's po file the next time
the translation is updated with `make update-po`.

"git log --grep=<string>" shows only commits with messages that
match the given string, but sometimes it is useful to be able to
show only commits that do *not* have certain messages (e.g. "show
me ones that are not FIXUP commits").
Now the underlying "git log" learned the "--invert-grep" option.
The option syntactically behaves similar to "--all-match" that
requires that all of the grep strings to match and semantically
behaves the opposite---it requires that none of the grep strings to
match.
Teach "gitk" to allow users to pass it down to underlying "git log"

If several gitk instances are closed simultaneously, the savestuff
procedure can run at the same time, resulting in a conflict which may
cause losing of some of the instance's changes, failing the saving
operation or even corrupting the configuration file. This can happen,
for example, at user session closing, or at group closing of all
instances of an application which is possible in some desktop
environments.
To avoid this, make sure that only one saving operation is in
progress. It is guarded by existence of the $config_file_tmp
file. Creating the file and moving it to $config_file are both atomic
operations, so it should be reliable.
Reading does not need to be syncronized, because moving is an atomic
operation, and the $config_file always refers to a full and correct file.
But, if there is a stale $config_file_tmp file, report it at gitk start.
If such file is detected when saving, just report it abort the save, as
for other errors in saving.

When gitk contains some changed parameter, and there is an existing
instance of gitk where the parameter is still old, it is reverted to
that old value when that instance exits.
Instead, store a parameter in config only if it has been modified in
the exiting instance. Otherwise, preserve the value which currently is in
file. This allows editing the configuration when several instances are
running, without rollback of the modification if some other
instance where the configuration was not edited is closed last.
For scalar variables, use trace(3tcl) to detect their change. Since
`trace` can send bogus events, doublecheck if the value has really
been changed, but once it is marked as changed, do not reset it back
to unchanged ever, because if user has restored the original value,
it's the decision which should be stored as well as modified value.
Treat view list especially: instead of rewriting the whole list, merge
individual views. Place old and updated views in their old places,
add new ones to the end of list. Collect modified views explicitly, in
newviewok{} and delview{}.
Do not merge geometry values. They are almost always changing because
user moves and resises windows, and there is no way to find which one of
the geometries is most desired. Just overwrite them unconditionally,
like earlier.

The current definition results in an incorrect expansion of the term under zsh.
For instance "/^${1////\\/}/" under zsh with the argument "hi" results in:
/^/\/h/\/i/
This results in an output similar to this when trying to complete `git grep
chartab` under zsh:
:: git grep chartabawk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
awk: cmd. line:1: ^ backslash not last character on line
awk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
awk: cmd. line:1: ^ syntax error
Leaving the prompt in a goofy state until the user hits a key.
Escaping the literal / in the parameter expansion (using "/^${1//\//\\/}/")
results in:
/^chartab/
allowing the completion to work correctly.
This formulation also works under bash.

We create 50,000 tags to check that we don't overflow the
command-line of fetch-pack. But by using run_with_cmdline_limit,
we can get the same effect with a much smaller number of
tags. This makes the test fast enough that we can drop the
EXPENSIVE prereq, which means people will actually run it.
It was not documented to do so, but this test was also the
only test of a clone-over-http that requires multiple POSTs
during the conversation. We can continue to test that by
dropping http.postbuffer to its minimum size, and checking
that we get two POSTs.

If you run a test script like:
GIT_TRACE=1 ./t0061-run-command.sh
you may get test failures, because some tests capture and
check the stderr output from git commands (and with
GIT_TRACE set to 1, the trace output will be included
there).
When we see GIT_TRACE set like this, we print a warning to
the user. However, we can do even better than that by just
pointing it to descriptor 4, which all tests leave connected
to the test script's stderr. That's likely what the user
intended (and any scripts that do want to see GIT_TRACE
output will set GIT_TRACE themselves).
Not only does this avoid false negatives in the tests, but
it means the user will actually see trace output for git
calls that redirect their stderr (whereas before, it was
sometimes confusingly buried in a file).

Right now if a test script receives SIGINT (e.g., because a
test was hanging and the user hit ^C), the shell exits
immediately. This can be annoying if the test script did any
global setup, like starting apache or git-daemon, as it will
not have an opportunity to clean up after itself. A
subsequent run of the test won't be able to start its own
daemon, and will either fail or skip the tests.
Instead, let's trap SIGINT to make sure we do a clean
shutdown, and just chain it to a normal exit (which will
trigger any cleanup).

We check whether the return value of lookup_unknown_object
is NULL, but some code paths dereference it before our
check. This turns out not to be capable of causing a
segfault, though. The lookup_unknown_object function will
never return NULL, since the whole point is to allocate an
object struct if it does not find an existing one. So the
code here is not wrong, it is just confusing. Let's just
drop the NULL check.

When upload-pack advertises the refs (either for a normal,
non-stateless request, or for the initial contact in a
stateless one), we call for_each_ref with the send_ref
function as its callback. send_ref, in turn, calls
mark_our_ref, which checks whether the ref is hidden, and
sets OUR_REF or HIDDEN_REF on the object as appropriate. If
it is hidden, mark_our_ref also returns "1" to signal
send_ref that the ref should not be advertised.
If we are not advertising refs, (i.e., the follow-up
invocation by an http client to send its "want" lines), we
use mark_our_ref directly as a callback to for_each_ref. Its
marking does the right thing, but when it then returns "1"
to for_each_ref, the latter interprets this as an error and
stops iterating. As a result, we skip marking all of the
refs that come lexicographically after it. Any "want" lines
from the client asking for those objects will fail, as they
were not properly marked with OUR_REF.
To solve this, we introduce a wrapper callback around
mark_our_ref which always returns 0 (even if the ref is
hidden, we want to keep iterating). We also tweak the
signature of mark_our_ref to exclude unnecessary parameters
that were present only to conform to the callback interface.
This should make it less likely for somebody to accidentally
use it as a callback in the future.
