* 'svn-fe' of git://repo.or.cz/git/jrn:
tests: kill backgrounded processes more robustly
vcs-svn: a void function shouldn't try to return something
tests: make sure input to sed is newline terminated
vcs-svn: add missing cast to printf argument
t0081 creates several background processes that write to a fifo and
then go to sleep for a while (so the reader of the fifo does not see
EOF).
Each background process is made in a curly-braced block in the shell,
and after we are done reading from the fifo, we use "kill $!" to kill
it off.
For a simple, single-command process, this works reliably and kills
the child sleep process. But for more complex commands like
"make_some_output && sleep", the results are less predictable. When
executing under bash, we end up with a subshell that gets killed by
the $! but leaves the sleep process still alive.
This is bad not only for process hygeine (we are leaving random sleep
processes to expire after a while), but also interacts badly with the
"prove" command. When prove executes a test, it does not realize the
test is done when it sees SIGCHLD, but rather waits until the test's
stdout pipe is closed. The orphaned sleep process may keep that pipe
open via test-lib's file descriptor 5, causing prove to hang for 100
seconds.
The solution is to explicitly use a subshell and to exec the final
sleep process, so that when we "kill $!" we get the process id of the
sleep process.
[jn: original patch by Jeff had some additional bits:
1. Wrap the "kill" in a test_when_finished, since we want
to clean up the process whether the test succeeds or not.
2. The "kill" is part of our && chain for test success. It
probably won't fail, but it can if the process has
expired before we manage to kill it. So let's mark it
as OK to fail.
I'm postponing that for now.]

vcs-svn: add missing cast to printf argument
In commit 95a1d12e9b ("tests: scrub environment of GIT_* variables") all
environment variables starting with "GIT_" were unset for the tests using
a perl script rather than unsetting them one by one. Only three exceptions
were made to make them work as before: "GIT_TRACE*", "GIT_DEBUG*" and
"GIT_USE_LOOKUP".
Unfortunately some environment variables used by the test framework itself
were not added to the exceptions and thus stopped working when given
before the make command instead of after it. Those are:
- GIT_NOTES_TIMING_TESTS
- GIT_PATCHID_TIMING_TESTS
- GIT_PROVE_OPTS
- GIT_REMOTE_SVN_TEST_BIG_FILES
- GIT_SKIP_TESTS
- GIT_TEST*
- GIT_VALGRIND_OPTIONS
I noticed that when skipping a test the way I was used to suddenly failed:
GIT_SKIP_TESTS='t1234' GIT_TEST_OPTS='--root=/dev/shm' make -j10 test
This should work according to t/README, but didn't anymore, so let's fix
that by adding them to the exception list. And to avoid having a long
regexp put the exceptions in a separate variable using nicer formatting.

Pass the log message by strbuf instead of as a C-style string and use

bytes can be preserved.
Currently "git log" doesn't show the embedded NULs but "git cat-file

source files need to include git-compat-util.h (or cache.h or

svn-fe errors out on revision 59151 of the ASF repository:
fatal: invalid dump: unexpected end of file
The proximate cause is a property with an embedded NUL character.
Previously such anomalies were ignored but commit c9d1c8ba
(2010-12-28) introduced a check strlen(val) == len to avoid reading
uninitialized data when a property list ends early and unfortunately
this test does not distinguish between "foo" followed by EOF and the
string "foo\0bar\0baz".
Fix it by using buffer_read_binary to read to a strbuf and checking
the actual length read. Most consumers of properties still use
C-style strings, so in practice an author or log message with embedded
NULs will be truncated, but a least this way svn-fe won't error out
(fixing the regression).

For a pull into an unborn branch, we do not use "git merge"

When we merge into an unborn branch, there are basically two
steps:
1. Write the sha1 of the new commit into the ref pointed
to by HEAD.
2. Update the index with the new content, and check it out
to the working tree.
We currently do them in this order. However, (2) is the step
that is much more likely to fail, since it can be blocked by
things like untracked working tree files. When it does, the
merge fails and we are left with an empty index but an
updated HEAD.
This patch switches the order, so that a failure in updating
the index leaves us unchanged. Of course, a failure in
updating the ref now leaves us with an updated index and
mis-matched HEAD. That is arguably not much better, but it
is probably less likely to actually happen.

This file ends up conflicting with the test just after it
(causing the "git merge" to fail). Neither test is to blame
for the bug, though. It looks like the merge in 1a9fe45
(Merge branch 'tr/merge-unborn-clobber', 2011-02-09) is what
caused the conflict.
We didn't notice because the follow-on test is already

We currently don't do break-detection at all in
merge-recursive. But there are some cases where it would
provide a more useful merge result.
For example, consider this case (which is the basis for the
new tests in t6039):
1. You rename a header file foo.h to bar.h. You install a
new foo.h that includes bar.h (for compatibility).
2. Another branch makes changes to foo.h.
When you merge, you want the changes the other branch made
to foo.h to migrate to the rename destination, bar.h, just
as you would if you hadn't installed that compatibility
header.
Similarly, you want the compatibility header left untouched.
The other side's changes all ended up in bar.h, so there is
no reason to conflict with the new content in foo.h.
This patch turns on break detection for merge-recursive. In
addition to new tests in t6039, it makes a similar test in
t3030 pass.

In this test, we have merge two branches. On one branch, we
renamed "a" to "e". On the other, we renamed "a" to "e" and
then added a symlink pointing at "a" pointing to "e".
The results for the test indicate that the merge should
succeed, but also that "a" should no longer exist. Since
both sides renamed "a" to the same destination, we will end
up comparing those destinations for content.
But what about what's left? One side (the rename only),
replaced "a" with nothing. The other side replaced it with a
symlink. The common base must also be nothing, because any
"a" before this was meaningless (it was totally unrelated
content that ended up getting renamed).
The only sensible resolution is to keep the symlink. The
rename-only side didn't touch the content versus the common
base, and the other side added content. The 3-way merge
dictates that we take the side with a change.
And this gives the overall merge an intuitive result. One
side made one change (a rename), and the other side made two
changes: an identical rename, and an addition (that just
happened to be at the same spot). The end result should
contain both changes.

Unlike bash and ksh, dash and busybox ash do not support brace
expansion (as in 'echo {hello,world}'). So when dash is sh,

Since e9c8409 (diff-index --cached --raw: show tree entry on the LHS for
unmerged entries., 2007-01-05), an unmerged entry should be detected by
using DIFF_PAIR_UNMERGED(p), not by noticing both one and two sides of
the filepair records mode=0 entries. However, it forgot to update some
parts of the rename detection logic.
This only makes difference in the "diff --cached" codepath where an
unmerged filepair carries information on the entries that came from the
tree. It probably hasn't been noticed for a long time because nobody
would run "diff -M" during a conflict resolution, but "git status" uses
rename detection when it internally runs "diff-index" and "diff-files"
and gives nonsense results.
In an unmerged pair, "one" side can have a valid filespec to record the
tree entry (e.g. what's in HEAD) when running "diff --cached". This can
be used as a rename source to other paths in the index that are not
unmerged. The path that is unmerged by definition does not have the
final content yet (i.e. "two" side cannot have a valid filespec), so it
can never be a rename destination.
Use the DIFF_PAIR_UNMERGED() to detect unmerged filepair correctly, and
allow the valid "one" side of an unmerged filepair to be considered a
potential rename source, but never to be considered a rename destination.

t6009: use test_commit() from test-lib.sh
The git-new-workdir script in contrib/ makes a new work tree by sharing
many subdirectories of the .git directory with the original repository.
When rerere.enabled is set in the original repository, but the user has
not encountered any conflicts yet, the original repository may not yet
have .git/rr-cache directory.
When rerere wants to run in a new work tree created from such a young
original repository, it fails to mkdir(2) .git/rr-cache that is a symlink
to a yet-to-be-created directory.
There are three possible approaches to this:
- A naive solution is not to create a symlink in the git-new-workdir
script to a directory the original does not have (yet). This is not a
solution, as we tend to lazily create subdirectories of .git/, and
having rerere.enabled configuration set is a strong indication that the
user _wants_ to have this lazy creation to happen;
- We could always create .git/rr-cache upon repository creation. This is
tempting but will not help people with existing repositories.
- Detect this case by seeing that mkdir(2) failed with EEXIST, checking
that the path is a symlink, and try running mkdir(2) on the link
target.
This patch solves the issue by doing the third one.
Strictly speaking, this is incomplete. It does not attempt to handle
relative symbolic link that points into the original repository, but this
is good enough to help people who use contrib/workdir/git-new-workdir
script.
