Fix checkout of large files to network shares on Windows XP
Bigger writes to network drives on Windows XP fail. Cap them at 31MB to
allow them to succeed. Callers need to be prepared for write() calls
that do less work than requested anyway.
On local drives, write() calls are translated to WriteFile() calls with
a cap of 64KB on Windows XP and 256KB on Vista. Thus a cap of 31MB won't
affect the number of WriteFile() calls which do the actual work. There's
still room for some other version of Windows to use a chunk size of 1MB
without increasing the number of system calls.

start_command: close cmd->err descriptor when fork/spawn fails
Fix the problem where the cmd->err passed into start_command wasn't
being properly closed when certain types of errors occurr. (Compare
the affected code with the clean shutdown code later in the function.)
On Windows, this problem would be triggered if mingw_spawnvpe()
failed, which would happen if the command to be executed was malformed
(e.g. a text file that didn't start with a #! line). If cmd->err was
a pipe, the failure to close it could result in a hang while the other
side was waiting (forever) for either input or pipe close, e.g. while
trying to shove the output into the side band. On msysGit, this
problem was causing a hang in t5516-fetch-push.

If we know we are creating a bare repository, we use setenv
to set the GIT_DIR directory to the current directory
(either where we already were, or one we created and chdir'd
into with "git init --bare <dir>").
However, with "git --bare init <dir>" (note the --bare as a
git wrapper option), the setup code actually sets GIT_DIR
for us, but it uses the wrong, original cwd when a directory
is given. Because our setenv does not use the overwrite
flag, it is ignored.
We need to set the overwrite flag, but only when we are
given a directory on the command line. That still allows:
GIT_DIR=foo.git git init --bare
to work. The behavior is changed for:
GIT_DIR=foo.git git init --bare bar.git
which used to create the repository in foo.git, but now will
use bar.git. This is more sane, as command line options
should generally override the environment.

Fix this by noticing the input and output encodings match and skipping

Also stop segfaulting on other iconv failures: if iconv fails for some
other reason, the best we can do is to pass the old message through.

test-lib: some shells do not let $? propagate into an eval
In 3bf7886 (test-lib: Let tests specify commands to be run at end of
test, 2010-05-02), the git test harness learned to run cleanup
commands unconditionally at the end of a test. During each test,
the intended cleanup actions are collected in the test_cleanup variable
and evaluated. That variable looks something like this:
All cleanup actions are run unconditionally but if one of them fails
it is properly reported through $eval_ret.
On FreeBSD, unfortunately, $? is set at the beginning of an ‘eval’
to 0 instead of the exit status of the previous command. This results
in tests using test_expect_code appearing to fail and all others
appearing to pass, unless their cleanup fails. Avoid the problem by
setting eval_ret before the ‘eval’ begins.
Thanks to Jeff King for the explanation.

Documentation/shortlog: scripted users should not rely on implicit HEAD
When passed no revision arguments, ‘git shortlog’ reads a log from
stdin if and only if stdin is not a tty. So scripts that need to
function identically when standard input is a terminal (as when run
interactively) and not (as when run through a cron job) should either
supply a log themselves or specify the desired revisions explicitly.

test-lib: Let tests specify commands to be run at end of test
Certain actions can imply that if the test fails early, recovery from
within other tests is too much to expect:
- creating unwritable directories, like the EACCESS test in t0001-init
- setting unusual configuration, like user.signingkey in t7004-tag
- crashing and leaving the index lock held, like t3600-rm once did
Some test scripts work around this by running cleanup actions outside
the supervision of the test harness, with the unfortunate consequence
that those commands are not appropriately echoed and their output not
suppressed. Others explicitly save exit status, clean up, and then
reset the exit status within the tests, which has excellent behavior
but makes the tests hard to read. Still others ignore the problem.
Allow tests a fourth option: by calling this function, tests can
stack up commands they would like to be run to clean up.
Commands passed to test_when_finished during a test are
unconditionally run in the test environment immediately before the
test is completed, in last-in-first-out order. If some cleanup
command fails, then the other cleanup commands are still run before
the failure is reported and the test script allowed to continue.

I'm not sure about the copyrightability of Bryan Donlan's
contributions (git log -p --author='Bryan Donlan' t/test-lib.sh).
Carl told me that in your ack collection process you missed only three
acks. So I wonder whether you already did some analysis of which
contributions are copyrightable. If so, are the missing acks in the
list bellow?

receive-pack: detect aliased updates which can occur with symrefs
When pushing to a remote repo the sending side filters out aliased
updates (e.g., foo:baz bar:baz). However, it is not possible for the
sender to know if two refs are aliased on the receiving side via
symrefs. Here is one such scenario:
Counting objects: 5, done.
Writing objects: 100% (3/3), 244 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
error: Ref refs/remotes/origin/master is at ef3... but expected 262...
remote: error: failed to lock refs/remotes/origin/master
To ../backup.git 262cd57..ef307ff master -> master 262cd57..ef307ff origin/HEAD -> origin/HEAD
! [remote rejected] origin/master -> origin/master (failed to lock)
error: failed to push some refs to '../backup.git'
The reason is that refs/remotes/origin/HEAD is a symref to
refs/remotes/origin/master, but it is not possible for the sending side
to unambiguously know this.
This commit fixes the issue by having receive-pack ignore any update to
a symref whose target is being identically updated. If a symref and its
target are being updated inconsistently, then the update for both fails
with an error message ("refusing inconsistent update...") to help
diagnose the situation.

http-fetch: Use index-pack rather than verify-pack to check packs
To ensure we don't leave a corrupt pack file positioned as though
it were a valid pack file, run index-pack on the temporary pack
before we rename it to its final name. If index-pack crashes out
when it discovers file corruption (e.g. GitHub's error HTML at the
end of the file), simply delete the temporary files to cleanup.
By waiting until the pack has been validated before we move it
to its final name, we eliminate a race condition where another
concurrent reader might try to access the pack at the same time
that we are still trying to verify its not corrupt.
Switching from verify-pack to index-pack is a change in behavior,
but it should turn out better for users. The index-pack algorithm
tries to minimize disk seeks, as well as the number of times any
given object is inflated, by organizing its work along delta chains.
The verify-pack logic does not attempt to do this, thrashing the
delta base cache and the filesystem cache.
By recreating the index file locally, we also can automatically
upgrade from a v1 pack table of contents to v2. This makes the
CRC32 data available for use during later repacks, even if the
server didn't have them on hand.

The easiest way to verify a pack index is to open it through the
standard parse_pack_index function, permitting the header check
to happen when the file is mapped. However, the dumb HTTP client
needs to verify a pack index before its moved into its proper file
name within the objects/pack directory, to prevent a corrupt index
from being made available. So permit the caller to specify the
exact path of the index file.
For now we're still using the final destination name within the
sole call site in http.c, but eventually we will start to parse
the temporary path instead.

Extract verify_pack_index for reuse from verify_pack
The dumb HTTP transport should verify an index is completely valid
before trying to use it. That requires checking the header/footer

function that can be reused.

By closing the pack index, a caller can later overwrite the index
with an updated index file, possibly after converting from v1 to
the v2 format. Because p->index_data is NULL after close, on the
next access the index will be opened again and the other members
will be updated with new data.
