Documentation: document show -sJonathan Nieder Tue, 9 Nov 2010 17:12:48 +0000 (11:12 -0600)

Documentation: document show -s

Git's diff machinery has supported a -s (silence diff output) option
as far back as v0.99~900 (Silent flag for show-diff, 2005-04-13), but
the option is only advertised in an odd corner of the git diff-tree
manual.

The main use is to retrieve basic metadata about a commit:

git show -s rev

Explain this in the 'git log' manual and provide an example in the
'git show' examples section. This is kind of a cop-out, since it
would be more useful to explain it in the 'git show' manual proper,
which says:

The command takes options applicable to the git
diff-tree command to control how the changes the
commit introduces are shown.

This manual page describes only the most frequently
used options.

Fixing that is a larger task for another day.

submodule: only preserve flags across recursive status... Kevin Ballard Wed, 3 Nov 2010 06:26:25 +0000 (23:26 -0700)

submodule: only preserve flags across recursive status/update invocations

Recursive invocations of submodule update/status preserve all arguments,
so executing

git submodule update --recursive -- foo

attempts to recursively update a submodule named "foo".

Naturally, this fails as one cannot have an infinitely-deep stack of
submodules each containing a submodule named "foo". The desired behavior
is instead to update foo and then recursively update all submodules
inside of foo.

This commit accomplishes that by only saving the flags for use in the
recursive invocation.

submodule: preserve all arguments exactly when recursing

Shell variables only hold strings, not lists of parameters,
so $orig_args after

orig_args="$@"

fails to remember where each parameter starts and ends, if
some include whitespace. So

git submodule update \
--reference='/var/lib/common objects.git' \
--recursive --init

becomes

git submodule update --reference=/var/lib/common \
objects.git --recursive --init

in the inner repositories. Use "git rev-parse --sq-quote" to
save parameters in quoted form ready for evaluation by the
shell, avoiding this problem.

apply: don't segfault on binary files with missing data

Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.

However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).

If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.

We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

config: treat non-existent config files as emptyJeff King Thu, 21 Oct 2010 14:45:44 +0000 (10:45 -0400)

config: treat non-existent config files as empty

The git_config() function signals error by returning -1 in
two instances:

1. An actual error occurs in opening a config file (parse
errors cause an immediate die).

2. Of the three possible config files, none was found.

However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.

This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.

git-gui: correct assignment of work-tree

git-gui currently uses its own logic to determine the work-tree setting
but 'git rev-parse --toplevel' directly returns git's work-tree value
by calling get_git_work_tree() and is therefore always correct.

This fixes an inability to handle some repository configurations. In
particular where .git is a file containing a path to the real directory
(a cross-platform symbolic link).
To continue to support older versions than 1.7.0, setting the work-tree
by normalizing the --show-cdup value is more reliable as git-dir might be
outside the work-tree entirely.

The "shortlog" command defaults to HEAD only when its standard input is
connected to a terminal; otherwise it acts in the traditional "filter"
mode to read and summarize the "git log" output.

Two new tests added to t4203 assumed that the command always default to
HEAD, but when the standard input is closed (or connected to /dev/null),
it output empty, which is a summary of its empty input, causing the test
to break.

repack: place temporary packs under .git/objects/pack/

git-pack-objects is already careful to start out its temporary packs
under .git/objects/pack/ (cf. 8b4eb6b, Do not perform cross-directory
renames when creating packs, 2008-09-22), but git-repack did not
respond in kind so the effort was lost when the filesystem boundary is
exactly at that directory.

Let git-repack pass a path under .git/objects/pack/ as the base for
its temporary packs.

This means we might need the $PACKDIR sooner (before the pack-objects
invocation), so move the mkdir up just to be safe.

Also note that the only use of *.pack is in the find invocation way
before the pack-objects call, so the temporary packs will not suddenly
show up in any wildcards because of the directory change.

Fix this, and update the tests to reflect this.

Note that according to the git-pack-objects documentation, we can safely
apply the usual --progress semantics for the transport commands like
clone and fetch (and for pushing over other smart transports).

test_terminal: ensure redirections work reliablyJonathan Nieder Sun, 17 Oct 2010 00:38:07 +0000 (19:38 -0500)

test_terminal: ensure redirections work reliably

For terminal tests that capture output/stderr, the TTY prerequisite
warning does not quite work for commands like

test_terminal foo >out 2>err

because the warning gets "swallowed" up by the redirection that's
supposed only to be done by the subcommand.

Even worse, the outcome depends on whether stdout was already a
terminal (in which case test_terminal is a noop) or not (in which case
test_terminal introduces a pseudo-tty in the middle of the pipeline).

$ test_terminal.perl sh -c 'test -t 1 && echo >&2 YES' >out
YES
$ sh -c 'test -t 1 && echo >&2 YES' >out
$

So:

- use the test_terminal script even when running with "-v".

- skip tests that require a terminal when the test_terminal
script is unusable because IO::Pty is not installed.

- write the "need to declare TTY prerequisite" message to fd 4,
where it will be printed when running tests with -v, rather
than being swallowed up by an unrelated redireciton.

test_terminal: catch use without TTY prerequisite

It is easy to forget to declare the TTY prerequisite when
writing tests on a system where it would always be satisfied

for example). Automatically detect this problem so there is
no need to remember.

test_must_fail: command not found: test_terminal echo hi

test_terminal returns status 127 in this case to simulate
not being available.

Also replace the SIMPLEPAGERTTY prerequisite on one test with
"SIMPLEPAGER,TTY", since (1) the latter is supported now and
(2) the prerequisite detection relies on the TTY prereq being

send-pack: avoid redundant "pack-objects died with strange error"

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant. The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).

Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.

So leave off the "strange error" messages.

The result should look something like this:

$ git push sf master
Counting objects: 21542, done.
Compressing objects: 100% (4179/4179), done.
fatal: Unable to create temporary file: Permission denied
error: pack-objects died of signal 13
error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
$

Or in the "controlled exit" case (contrived example):

[...]
fatal: delta size changed
error: failed to push some refs to 'ssh://example.com/foo/bar'
$

mailmap: fix use of freed memory

On an x86_64 system (F13-based), I ran these commands in an empty directory:

git init
printf '%s\n' \
'<jdoe@example.com> <jdoe@example.COM>' \
'John <jdoe@example.com>' > .mailmap
git shortlog < /dev/null

Here's the result:

(reading log message from standard input)
*** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 ***
======= Backtrace: =========
/lib64/libc.so.6[0x31ba875676]
git[0x48c2a5]
git[0x4b9858]
...
zsh: abort (core dumped) git shortlog

What happened?

Some .mailmap entry is of the <email1> <email2> form,
while a subsequent one looks like "User Name <Email2>,
and the two email addresses on the right are not identical
but are "equal" when using a case-insensitive comparator.

Then, when add_mapping is processing the latter line, new_email is NULL
and we free me->email, yet do not replace it with a new strdup'd string.
Thus, when later we attempt to use the buffer behind that ->email pointer,
we reference freed memory.

The solution is to free ->email and ->name only if we're about to replace them.
