Shawn O. Pearce 14d4642e2a Fix describe --tags --long so it does not segfault
If we match a lightweight (non-annotated tag) as the name to
output and --long was requested we do not have a tag, nor do
we have a tagged object to display.  Instead we must use the
object we were passed as input for the long format display.

Thomas Rast 4f3dcc2753 Fix 'git show' on signed tag of signed tag of commit
The cmd_show loop resolves tags by showing them, then pointing the
object to the 'tagged' member.  However, this object is not fully
initialized; it only contains the SHA1.  (This resulted in a segfault
if there were two levels of tags.)  We apply parse_object to get a
full object.

Jeff King a0d2ceb276 doc/rev-parse: clarify reflog vs --until for specifying revisions
The rev-parse manpage introduces the branch@{date} syntax,
and mentions the reflog specifically. However, new users may
not be familiar with the distinction between the reflog and
the commit date, so let's help them out with a "you may be
interested in --until" pointer.

Avery Pennarun 29c70e0b3e git-svn: avoid filling up the disk with temp files.
Commit ffe256f9ba ("git-svn: Speed up fetch")
introduced changes that create a temporary file for each object fetched by
svn.  These files should be deleted automatically, but perl apparently
doesn't do this until the process exits (or perhaps when its garbage
collector runs).

This means that on a large fetch, especially with lots of branches, we
sometimes fill up /tmp completely, which prevents the next temp file from
being written completely.  This is aggravated by the fact that a new temp
file is created for each updated file, even if that update produces a file
identical to one already in git.  Thus, it can happen even if there's lots
of disk space to store the finished repository.

We weren't adequately checking for write errors, so this would result in an
invalid file getting committed, which caused git-svn to fail later with an
invalid checksum.

This patch adds a check to syswrite() so similar problems don't lead to
corruption in the future.  It also unlink()'s each temp file explicitly
when we're done with it, so the disk doesn't need to fill up.

Jeff King 2beebd22f4 clone: create intermediate directories of destination repo
The shell version used to use "mkdir -p" to create the repo
path, but the C version just calls "mkdir". Let's replicate
the old behavior. We have to create the git and worktree
leading dirs separately; while most of the time, the
worktree dir contains the git dir (as .git), the user can
override this using GIT_WORK_TREE.

We can reuse safe_create_leading_directories, but we need to
make a copy of our const buffer to do so. Since
merge-recursive uses the same pattern, we can factor this
out into a global function. This has two other cleanup
advantages for merge-recursive:

  1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually
     creates bar, but this function just creates the leading
     directories.

  2. mkdir_p took a mode argument, but it was completely
     ignored.

Jan Krüger 74b1e12357 git-svn: make rebuild respect rewriteRoot option
Suppose someone fetches git-svn-ified commits from another repo and then
attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase
after that will fail badly:

 * For each commit tried by working_head_info, rebuild is called indirectly.
 * rebuild will iterate over all commits and skip all of them because the
   URL does not match. Because of that no rev_map file is generated at all.
 * Thus, rebuild will run once for every commit. This takes ages.
 * In the end there still isn't any rev_map file and thus working_head_info
   fails.

Addressing this behaviour fixes an apparently not too uncommon problem with
providing git-svn mirrors of Subversion repositories. Some repositories are
accessed using different URLs depending on whether the user has push
privileges or not. In the latter case, an anonymous URL is often used that
differs from the push URL. Providing a mirror that is usable in both cases
becomes a lot more possible with this change.

Linus Torvalds 044bbbcb63 Make git_dir a path relative to work_tree in setup_work_tree()
Once we find the absolute paths for git_dir and work_tree, we can make
git_dir a relative path since we know pwd will be work_tree. This should
save the kernel some time traversing the path to work_tree all the time
if git_dir is inside work_tree.

Daniel's patch didn't apply for me as-is, so I recreated it with some
differences, and here are the numbers from ten runs each.

There is some IO for me - probably due to more-or-less random flushing of
the journal - so the variation is bigger than I'd like, but whatever:

	Before:
		real    0m8.135s
		real    0m7.933s
		real    0m8.080s
		real    0m7.954s
		real    0m7.949s
		real    0m8.112s
		real    0m7.934s
		real    0m8.059s
		real    0m7.979s
		real    0m8.038s

	After:
		real    0m7.685s
		real    0m7.968s
		real    0m7.703s
		real    0m7.850s
		real    0m7.995s
		real    0m7.817s
		real    0m7.963s
		real    0m7.955s
		real    0m7.848s
		real    0m7.969s

Now, going by "best of ten" (on the assumption that the longer numbers
are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does
seem to be outside of the noise (ie the "after" case never broke 8s, while
the "before" case did so half the time).

So looks like about 3% to me.

Doing it for a slightly smaller test-case (just the "arch" subdirectory)
gets more stable numbers probably due to not filling the journal with
metadata updates, so we have:

	Before:
		real    0m1.633s
		real    0m1.633s
		real    0m1.633s
		real    0m1.632s
		real    0m1.632s
		real    0m1.630s
		real    0m1.634s
		real    0m1.631s
		real    0m1.632s
		real    0m1.632s

	After:
		real    0m1.610s
		real    0m1.609s
		real    0m1.610s
		real    0m1.608s
		real    0m1.607s
		real    0m1.610s
		real    0m1.609s
		real    0m1.611s
		real    0m1.608s
		real    0m1.611s

where I'ld just take the averages and say 1.632 vs 1.610, which is just
over 1% peformance improvement.

So it's not in the noise, but it's not as big as I initially thought and
measured.

(That said, it obviously depends on how deep the working directory path is
too, and whether it is behind NFS or something else that might need to
cause more work to look up).

Brandon Casey e200783255 t7502-commit.sh: test_must_fail doesn't work with inline environment variables
When the arguments to test_must_fail() begin with a variable assignment,
test_must_fail() attempts to execute the variable assignment as a command.
This fails, and so test_must_fail returns with a successful status value
without running the command it was intended to test.

For example, the following script:

	#!/bin/sh
	test_must_fail () {
		"$@"
		test $? -gt 0 -a $? -le 129
	}
	foo='wo adrian'
	test_must_fail foo='yo adrian' sh -c 'echo foo: $foo'

always exits zero and prints the message:

	test.sh: line 3: foo=yo adrian: command not found

Test 16 calls test_must_fail in such a way and therefore has not been
testing whether git 'do[es] not fire editor in the presence of conflicts'.

A workaround is to set and export the variable in a normal way, not
using one-shot notation.  Because this would affect the remainder of
the process, the test is done inside a subshell.

Jeff King 9a7bbd1dd1 clean up error conventions of remote.c:match_explicit
match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec.  Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.

It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).

This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.

At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.

This change fixes two bugs, as well:

  - the early return avoids a segfault when passing a NULL
    matched_src to guess_ref()

  - the check for multiple sources pointing to a single dest
    aborted if the "err" flag was set. Presumably the intent
    was not to bother with the check if we had no
    matched_src. However, since the err flag was passed in
    from the caller, we might abort the check just because a
    previous refspec had a problem, which doesn't make
    sense.

    In practice, this didn't matter, since due to the error
    flag we end up aborting the push anyway.

Linus Torvalds 1421c5f274 write_loose_object: don't bother trying to read an old object
Before even calling this, all callers have done a "has_sha1_file(sha1)"
or "has_loose_object(sha1)" check, so there is no point in doing a
second check.

If something races with us on object creation, we handle that in the
final link() that moves it to the right place.

Miklos Vajna 9e18522328 run-command documentation: fix "memset()" parameter
When initializing the struct async and struct child_process structures,
the documentation suggested "clearing" the structure with '0' instead of
'\0'.  It is enough to use integer zero here.
