1bba00130a describe: prepend "tags/" when describing tags with embedded name
The man page of the "git describe" command explains the expected
output when using the --all option, i.e. the full reference path is
shown, including heads/ or tags/ prefix.

When 212945d4a8 ("Teach git-describe
to verify annotated tag names before output") made Git favor the
embedded name of annotated tags, it accidentally changed the output
format when the --all flag is given, only printing the tag's name
without the prefix.

Check if --all was specified and re-add the "tags/" prefix for this
special case to fix the regresssion.

ed1e52822e sequencer: assign only free()able strings to gpg_sign
The gpg_sign member of the replay_opts structure is of type `char *`,
meaning that the sequencer deems the string to which gpg_sign points to
be under its custody, i.e. it needs to be free()d by the sequencer.

Therefore, let's only assign malloc()ed buffers to it.

8cf422dbf1 git-p4: update multiple shelved change lists
--update-shelve can now be specified multiple times on the
command-line, to update multiple shelved changelists in a single
submit.

This then means that a git patch series can be mirrored to a
sequence of shelved changelists, and (relatively easily) kept in
sync as changes are made in git.

Note that Perforce does not really support overlapping shelved
changelists where one change touches the files modified by
another. Trying to do this will result in merge conflicts.

30884c9afc commit: add support for --fixup <commit> -m"<extra message>"
Add support for supplying the -m option with --fixup. Doing so has
errored out ever since --fixup was introduced. Before this, the only
way to amend the fixup message while committing was to use --edit and
amend it in the editor.

The use-case for this feature is one of:

 * Leaving a quick note to self when creating a --fixup commit when
   it's not self-evident why the commit should be squashed without a
   note into another one.

 * (Ab)using the --fixup feature to "fix up" commits that have already
   been pushed to a branch that doesn't allow non-fast-forwards,
   i.e. just noting "this should have been part of that other commit",
   and if the history ever got rewritten in the future the two should
   be combined.

   In such a case you might want to leave a small message,
   e.g. "forgot this part, which broke XYZ".

With this, --fixup <commit> -m"More" -m"Details" will result in a
commit message like:

    !fixup <subject of <commit>>

    More

    Details

The reason the test being added here seems to squash "More" at the end
of the subject line of the commit being fixed up is because the test
code is using "%s%b" so the body immediately follows the subject, it's
not a bug in this code, and other tests t7500-commit.sh do the same
thing.

When the --fixup option was initially added the "Option -m cannot be
combined" error was expanded from -c, -C and -F to also include
--fixup[1]

Those options could also support combining with -m, but given what
they do I can't think of a good use-case for doing that, so I have not
made the more invasive change of splitting up the logic in commit.c to
first act on those, and then on -m options.

7dbe8c8003 check-non-portable-shell.pl: wc -l may have leading WS
Test scripts count number of lines in an output and check it againt
its expectation.  fb3340a6 ("test-lib: introduce test_line_count to
measure files", 2010-10-31) introduced a helper to show a failure in
such a test in a more readable way than comparing `wc -l` output with
a number.

Besides, on some platforms, "$(wc -l <file)" is padded with leading
whitespace on the left, so

	test "$(wc -l <file)" = 4

would not work (most notably on macosX); the users of test_line_count
helper would not suffer from such a portability glitch.

Add a check in check-non-portable-shell.pl to find '"' between
`wc -l` and '=' and hint the user about test_line_count().

2017-12-22 12:48:38 -08:00
Elijah Newren
65170c07d4 merge-recursive: avoid incorporating uncommitted changes in a merge
builtin/merge.c contains this important requirement for merge strategies:
	/*
	 * At this point, we need a real merge.  No matter what strategy
	 * we use, it would operate on the index, possibly affecting the
	 * working tree, and when resolved cleanly, have the desired
	 * tree in the index -- this means that the index must be in
	 * sync with the head commit.  The strategies are responsible
	 * to ensure this.
	 */

merge-recursive does not do this check directly, instead it relies on
unpack_trees() to do it.  However, merge_trees() has a special check for
the merge branch exactly matching the merge base; when it detects that
situation, it returns early without calling unpack_trees(), because it
knows that the HEAD commit already has the correct result.  Unfortunately,
it didn't check that the index matched HEAD, so after it returned, the
outer logic ended up creating a merge commit that included something
other than HEAD.

74dea0e13c t/helper/test-lazy-name-hash: fix compilation

I do not see how we can arrive at that line without having `nr_threads_used`
initialized, as we'd have `count > 1`  (which asserts that we ran the
loop above at least once, such that it *should* be initialized).

Just clear the variable at the beginning of the function to squelch
the warning.

fb2afea366 t5573, t7612: clean up after unexpected success of 'pull' and 'merge'
The previous steps added test_when_finished to tests that run 'git
pull' or 'git merge' with expectation of success, so that the test
after them can start from a known state even when their 'git pull'
invocation unexpectedly fails.  However, tests that run 'git pull'
or 'git merge' expecting it not to succeed forgot to protect later
tests the same way---if they unexpectedly succeed, the test after
them would start from an unexpected state.

Reset and checkout the initial commit after all these tests, whether
they expect their invocations to succeed or fail.

644eb60bd0 builtin/describe.c: describe a blob
Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])

When describing commits, we try to anchor them to tags or refs, as these
are conceptually on a higher level than the commit. And if there is no ref
or tag that matches exactly, we're out of luck.  So we employ a heuristic
to make up a name for the commit. These names are ambiguous, there might
be different tags or refs to anchor to, and there might be different
path in the DAG to travel to arrive at the commit precisely.

When describing a blob, we want to describe the blob from a higher layer
as well, which is a tuple of (commit, deep/path) as the tree objects
involved are rather uninteresting.  The same blob can be referenced by
multiple commits, so how we decide which commit to use?  This patch
implements a rather naive approach on this: As there are no back pointers
from blobs to commits in which the blob occurs, we'll start walking from
any tips available, listing the blobs in-order of the commit and once we
found the blob, we'll take the first commit that listed the blob. For
example

  git describe --tags v0.99:Makefile
  conversion-901-g7672db20c2:Makefile

tells us the Makefile as it was in v0.99 was introduced in commit 7672db20.

The walking is performed in reverse order to show the introduction of a
blob rather than its last occurrence.

The return code of command -v with a non-existing command is 1 in bash

work with dash and without watchman (e.g. on Debian).

While at it stop redirecting the output.  stderr is redirected to
/dev/null by test_lazy_prereq already, and stdout can actually be
useful -- the path of the found watchman executable is sent there, but
it's shown only if the script was run with --verbose.

bf9d7df950 t/lib-git-svn.sh: improve svnserve tests with parallel make test
Setting SVNSERVE_PORT enables several tests which require a local
svnserve daemon to be run (in t9113 & t9126).  The tests share setup of
the local svnserve via `start_svnserve()`.  The function uses svnserve's
`--listen-once` option, which causes svnserve to accept one connection
on the port, serve it, and exit.  When running the tests in parallel
this fails if one test tries to start svnserve while the other is still
running.

Use the test number as the svnserve port (similar to httpd tests) to
avoid port conflicts.  Developers can set GIT_TEST_SVNSERVE to any value
other than 'false' or 'auto' to enable these tests.

but the explicit .gitignore file is not updated in the same commit, or

b3b05971c1 clone: support 'clone --shared' from a worktree
When worktree functionality was originally implemented, the possibility
of 'clone --local' from within a worktree was overlooked, with the
result that the location of the "objects" directory of the source
repository was computed incorrectly, thus the objects could not be
copied or hard-linked by the clone. This shortcoming was addressed by
744e469755 (clone: allow --local from a linked checkout, 2015-09-28).

However, the related case of 'clone --shared' (despite being handled
only a few lines away from the 'clone --local' case) was not fixed by
744e469755, with a similar result of the "objects" directory location
being incorrectly computed for insertion into the 'alternates' file.
Fix this.

20d2a30f8f Makefile: replace perl/Makefile.PL with simple make rules
Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].

The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.

We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].

There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.

So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").

While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.

Functional changes:

 * This will not always install into perl's idea of its global
   "installsitelib". This only potentially matters for packagers that
   need to expose Git.pm for non-git use, and as explained in the
   INSTALL file there's a trivial workaround.

 * The scripts themselves will 'use lib' the target directory, but if
   INSTLIBDIR is set it overrides it. It doesn't have to be this way,
   it could be set in addition to INSTLIBDIR, but my reading of [7] is
   that this is the desired behavior.

 * We don't build man pages for all of the perl modules as we used to,
   only Git(3pm). As discussed on-list[8] that we were building
   installed manpages for purely internal APIs like Git::I18N or
   private-Error.pm was always a bug anyway, and all the Git::SVN::*
   ones say they're internal APIs.

   There are apparently external users of Git.pm, but I don't expect
   there to be any of the others.

   As a side-effect of these general changes the perl documentation
   now only installed by install-{doc,man}, not a mere "install" as
   before.

c0c578b33c unpack-trees: batch fetching of missing blobs
When running checkout, first prefetch all blobs that are to be updated
but are missing. This means that only one pack is downloaded during such
operations, instead of one per missing blob.

This operates only on the blob level - if a repository has a missing
tree, they are still fetched one at a time.

This does not use the delayed checkout mechanism introduced in commit
2841e8f ("convert: add "status=delayed" to filter process protocol",
2017-06-30) due to significant conceptual differences - in particular,
for partial clones, we already know what needs to be fetched based on
the contents of the local repo alone, whereas for status=delayed, it is
the filter process that tells us what needs to be checked in the end.
