c8b296450e 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.

fc012c2810 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.

[J6t: With a slight adjustment of the test case, the hang is also
observed on Linux.]

  handle "git --bare init <dir>" properly
2010-05-10 18:34:03 -07:00
Jeff King
87a074df24 handle "git --bare init <dir>" properly
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.

Noticed by Oliver Hoffmann.

b6b0afdc30 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:

	eval_ret=$?; clean_something && (exit "$eval_ret")
	eval_ret=$?; clean_something_else && (exit "$eval_ret")
	eval_ret=$?; final_cleanup && (exit "$eval_ret")
	eval_ret=$?

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.

3bf7886705 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.

64b90323f6 test-lib.sh: Add explicit license detail, with change from GPLv2 to GPLv2+.
Dear Junio,

this is a resend of relicensing patch for test suite library, which
was initially sent by Carl Worth. Since the time you sent me acks for
this patch collected by you, I collected 8 additional acks as is
documented at
https://git.wiki.kernel.org/index.php/Test-lib_reclicensing. There are
still three contributors missing: Bert Wesarg, Stephan Beyer and Bryan
Donlan. The contributions of first two are clearly not copyrightable.
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?

Thanks
Michal

8<--------8<--------8<--------
This file has had no explicit license information noted in it, but
has clearly been created and modified according to the terms of GPLv2
as with the rest of the git code base.

The purpose of relicensing is to allow other GPLv3+ projects (in
particular, the notmuch project: http://notmuchmail.org) to use this
same test-suite structure and to contribute changes back as well.

da3efdb17b 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:

  $ git init origin
  $ (cd origin && touch file && git add file && git commit -a -m intial)
  $ git clone --bare origin origin.git
  $ rm -rf origin

  $ git clone origin.git client

  $ git clone --mirror client backup.git &&
  $ (cd backup.git && git remote set-head origin --auto)

  $ (cd client &&
	git remote add --mirror backup ../backup.git &&
	echo change1 > file && git commit -a -m change1 &&
	git push origin &&
	git push backup
	)

The push to backup fails with:

  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.

This prevents a corrupt index file from later being treated as a

fetch_pack_index(); that way, we can do without the has_pack_index()

fe72d420ab 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.

713c79e84b more war on "sleep" in tests
Two more tests that sleep only to waste tick can be converted to use
test_tick and take expiry parameters relative to $test_tick.  The basic
idea is to replace "sleep 1" with "test_tick" to cause the "time" to pass.

These tests are interested in expiring things with "now" as the timestamp,

d761b2ac0e t5550-http-fetch: Use subshell for repository operations
Change into the server repository's directory using a subshell,
so we can return back to the top of the trash directory before
doing anything more in the test script.

53b3c47d64 t1010-mktree: Adjust expected result to code and documentation
The last two tests here were always supposed to fail in the sense
that, according to code and documentation, mktree should read non-recursive
ls-tree output, but not recursive one, and therefore explicitely refuses
to deal with slashes.

Adjust the test (must_fail) so that it succeeds when mktree dies on
slashes.

2179870803 combined diff: correctly handle truncated file
Consider an evil merge of two commits A and B, both of which have a
file 'foo', but the merge result does not have that file.

The combined-diff code learned in 4462731 (combine-diff: do not punt
on removed or added files., 2006-02-06) to concisely show only the
removal, since that is the evil part and the previous contents are
presumably uninteresting.

However, to diagnose an empty merge result, it overloaded the variable
that holds the file's length.  This means that the check also triggers
for truncated files.  Consequently, such files were not shown in the
diff at all despite the merge being clearly evil.

Fix this by adding a new variable that distinguishes whether the file
was deleted (which is the case 4462731 handled) or truncated.  In the
truncated case, we show the full combined diff again, which is rather
spammy but at least does not hide the evilness.

882749a04f diff: add --word-diff option that generalizes --color-words
This teaches the --color-words engine a more general interface that
supports two new modes:

* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
  'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}

* --word-diff=porcelain, which generates an ad-hoc machine readable
  format:
  - each diff unit is prefixed by [-+ ] and terminated by newline as
    in unified diff
  - newlines in the input are output as a line consisting only of a
    tilde '~'

Both of these formats still support color if it is enabled, using it
to highlight the differences.  --color-words becomes a synonym for
--word-diff=color, which is the color-only format.  Also adds some
compatibility/convenience options.

Thanks to Junio C Hamano and Miles Bader for good ideas.

03e8b541b3 describe: Break annotated tag ties by tagger date
If more than one annotated tag points at the same commit, use the
tag whose tagger field has a more recent date stamp.  This resolves
non-deterministic cases where the maintainer has done:

  $ git tag -a -m "2.1-rc1" v2.1-rc1  deadbeef
  $ git tag -a -m "2.1"     v2.1      deadbeef

If the tag is an older-style annotated tag with no tagger date, we
assume a date stamp at the UNIX epoch. This will cause us to prefer
an annotated tag that has a valid date.

We could also try to consider the tag object chain, favoring a tag
that "includes" another one:

  $ git tag -a -m "2.1-rc0" v2.1-rc1  deadbeef
  $ git tag -a -m "2.1"     v2.1      v2.1-rc1

However traversing the tag's object chain looking for inclusion
is much more complicated.  Its already very likely that even in
these cases the v2.1 tag will have a more recent tagger date than
v2.1-rc1, so with this change describe should still resolve this
by selecting the more recent v2.1.
