* 'svn-fe' of git://repo.or.cz/git/jrn:

  vcs-svn: a void function shouldn't try to return something

Jeff King a892a2ddfe tests: kill backgrounded processes more robustly
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.]

Do not advertise no-done capability when upload-pack is not serving over

reading in-flight data from the client, even though it is necessary to
drain all the in-flight data in order to unblock the client.

Junio C Hamano 44d8dc54e7 Fix potential local deadlock during fetch-pack
The fetch-pack/upload-pack protocol relies on the underlying transport
(local pipe or TCP socket) to have enough slack to allow one window worth
of data in flight without blocking the writer.  Traditionally we always
relied on being able to have two windows of 32 "have"s in flight (roughly
3k bytes) to stream.

The recent "progressive-stride" change allows "fetch-pack" to send up to
1024 "have"s without reading any response from "upload-pack".  The
outgoing pipe of "upload-pack" can be clogged with many ACK and NAK that
are unread, while "fetch-pack" is still stuffing its outgoing pipe with
more "have"s, leading to a deadlock.

Revert the change unless we are in stateless rpc (aka smart-http) mode, as
using a large window full of "have"s is still a good way to help reduce
the number of back-and-forth, and there is no buffering issue there (it is
strictly "ping-pong" without an overlap).

Junio C Hamano 8e9182e091 enable "no-done" extension only when fetching over smart-http
When 'no-done' protocol extension is used, the upload-pack (i.e. the
server side) process stops listening to the fetch-pack after issuing the
final NAK, and starts sending the generated pack data back, but there may
be more "have" send by the latter in flight that the fetch-pack is
expecting to be responded with ACK/NAK.  This will typically result in a
deadlock (both will block on write that the other end never reads) or
SIGPIPE on the fetch-pack end (upload-pack will finish writing a small
pack and goes away).

Disable it unless fetch-pack is running under smart-http, where there is
no such streaming issue.

Jens Lehmann 730477f199 tests: fix overeager scrubbing of environment variables
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.

Giuseppe Bilotta cea13a8d68 Improve test for pthreads flag
When compiling with CC=clang using Clang 1.1 as shipped by Debian
unstable (package version 2.7-3), the -mt flag is sufficient to compile

link time complaining about missing symbols such as `pthread_key_create'
and `pthread_create'.

Work around this issue by adding pthread key creation to the pthreads

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
commit" can.

While at it, stop including system headers from repo_tree.h.  git
source files need to include git-compat-util.h (or cache.h or
builtin.h) sooner to ensure the appropriate feature test macros are
defined.

Jonathan Nieder e7d04ee147 vcs-svn: make reading of properties binary-safe
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).

Jeff King 97b1b4f3a6 merge: merge unborn index before setting ref
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.

Jakub Narebski 2b1e17237b gitweb: Fix handling of fractional timezones in parse_date
Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.

This was caused by two mistakes:

* sign of timezone was applied only to hour part of offset, and not
  as it should be also to minutes part (this affected only negative
  fractional timezones).

* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
  so fractional part was discarded altogether ($h is hours, $m is
  minutes, which is always less than 60).

Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.

For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of
"Sat Jan 9 00:18:07 2010 +0530".
