61b472ed8b git svn: reset invalidates the memoized mergeinfo caches
Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30),
git-svn has maintained some private per-repository caches in
.git/svn/.caches to avoid refetching and recalculating some
mergeinfo-related information with every 'git svn fetch'.

This memoization can cause problems, e.g consider the following case:

SVN repo:

  ... - a - b - c - m  <- trunk
          \        /
            d  -  e    <- branch1

The Git import of the above repo is at commit 'a' and doesn't know about
the branch1. In case of an 'git svn rebase', only the trunk of the
SVN repo is imported. During the creation of the git commit 'm', git svn
uses the svn:mergeinfo property and tries to find the corresponding git
commit 'e' to create 'm' with 'c' and 'e' as parents. But git svn rebase
only imports the current branch so commit 'e' is not imported.
Therefore git svn fails to create commit 'm' as a merge commit, because one
of its parents is not known to git. The imported history looks like this:

  ... - a - b - c - m  <- trunk

A later 'git svn fetch' to import all branches can't rewrite the commit 'm'
to add 'e' as a parent and to make it a real git merge commit, because it
was already imported.

That's why the imported history misses the merge and looks like this:

  ... - a - b - c - m  <- trunk
          \
            d  -  e    <- branch1

Right now the only known workaround for importing 'm' as a merge is to
force reimporting 'm' again from SVN, e.g. via

  $ git svn reset --revision $(git find-rev $c)
  $ git svn fetch

Sadly, this is where the behavior has regressed: git svn reset doesn't
invalidate the old mergeinfo cache, which is no longer valid for the
reimport, which leads to 'm' beeing imprted with only 'c' as parent.

As solution to this problem, this commit invalidates the mergeinfo cache
to force correct recalculation of the parents.

During development of this patch, several ways for invalidating the cache
where considered. One of them is to use Memoize::flush_cache, which will
call the CLEAR method on the underlying Memoize persistency implementation.
Sadly, neither Memoize::Storable nor the newer Memoize::YAML module
introduced in 68f532f4ba could optionally be used implement the
CLEAR method, so this is not an option.

Reseting the internal hash used to store the memoized values has the same
problem, because it calls the non-existing CLEAR method of the
underlying persistency layer, too.

Considering this and taking into account the different implementations
of the memoization modules, where Memoize::Storable is not in our control,
implementing the missing CLEAR method is not an option, at least not if
Memoize::Storable is still used.

Therefore the easiest solution to clear the cache is to delete the files
on disk in 'git svn reset'. Normally, deleting the files behind the back
of the memoization module would be problematic, because the in-memory
representation would still exist and contain wrong data. Fortunately, the
memoization is active in memory only for a small portion of the code.
Invalidating the cache by deleting the files on disk if it isn't active
should be safe.

e48fb750f5 git svn: handle errors and concurrent commits in dcommit
dcommit didn't handle errors returned by SVN and coped very
poorly with concurrent commits that appear in SVN repository
while dcommit was running. In both cases it left git repository
in inconsistent state: index (which was reset with `git reset
--mixed' after a successful commit to SVN) no longer matched the
checkouted tree, when the following commit failed or needed to be
rebased. See http://bugs.debian.org/676904 for examples.

This patch fixes the issues by:
- introducing error handler for dcommit. The handler will try
  to rebase or reset working tree before returning error to the
  end user. dcommit_rebase function was extracted out of cmd_dcommit
  to ensure consistency between cmd_dcommit and the error handler.
- calling `git reset --mixed' only once after all patches are
  successfully committed to SVN. This ensures index is not touched
  for most of the time of dcommit run.

Since commit bbc09c22 ("grep: rip out support for external grep",
12-01-2010), test number 60 ("grep -C1 hunk mark between files") is
essentially the same as test number 59.

Test 59 was intended to verify the behaviour of git-grep resulting
from multiple invocations of an external grep. As part of the test,
it creates and adds 1024 files to the index, which is now wasted
effort.

Remove test 59, since it is now redundant.

425b8a22aa t1100-*.sh: Fix an intermittent test failure
In particular, the final test ('flags and then non flags') fails
intermittently, depending on how much time elapsed between the
invocations of "git commit-tree" when creating the commits which
later have their commit id's compared. For example, if the commits
for childid-3 and childid-4 are created 1 or more seconds apart,
then the commits, which would otherwise be identical, will have
different commit id's.

In order to make the test reproducible, we remove the variability
by setting the author and committer times to a well defined state.
We accomplish this with a single call to 'test_tick' at the start
of the test.

8c8b3bc3f4 t7502: test early quit from commit with bad ident
In commit f20f387, "git commit" notices and dies much
earlier when we have a bogus commit identity. That commit
did not add a test because we cannot do so reliably (namely,
we can only trigger the behavior on a system where the
automatically generated identity is bogus). However, now
that we have a prerequisite check for this feature, we can
add a test that will at least run on systems that produce
such a bogus identity.

1d7dc26498 t7502: handle systems where auto-identity is broken
Test t7502.21 checks whether we write the committer name
into COMMIT_EDITMSG when it has been automatically
determined. However, not all systems can produce valid
automatic identities.

Prior to f20f387 (commit: check committer identity more
strictly), this test worked even when we did not have a
valid automatic identity, since it did not run the strict
test until after we had generated the template. That commit
tightened the check to fail early (since we would fail
later, anyway), meaning that systems without a valid GECOS
name or hostname would fail the test.

We cannot just work around this, because it depends on
configuration outside the control of the test script.
Therefore we introduce a new test_prerequisite to run this
test only on systems where automatic ident works at all.

As a result, we can drop the confusing test_must_fail bit
from the test. The intent was that by giving "git commit"
invalid input (namely, nothing to commit), that it would
stop at a predictable point, whether we had a valid identity
or not, from which we could view the contents of
COMMIT_EDITMSG. Since that assumption no longer holds, and
we can only run the test when we have a valid identity,
there is no reason not to let commit run to completion. That
lets us be more robust to other unforeseen failures.

ceacd91a06 t7502: drop confusing test_might_fail call
In t7502.20, we run "git commit" and check that it warns us
that the author and committer identity are not the same
(this is always the case in the test environment, since we
set up the idents differently).

Instead of actually making a commit, we have a clean index,
so the "git commit" we run will fail. This is marked as
might_fail, which is not really correct; it will always fail
since there is nothing to commit.

However, the only reason not to do a complete commit would
be to see the intermediate state of the COMMIT_EDITMSG file
when the commit is not completed. We don't need to care
about this, though; even a complete commit will leave
COMMIT_EDITMSG for us to view.  By doing a real commit and
dropping the might_fail, we are more robust against other
unforeseen failures of "git commit" that might influence our
test result.

It might seem less robust to depend on the fact that "git
commit" leaves COMMIT_EDITMSG in place after a successful
commit. However, that brings this test in line with others
parts of the script, which make the same assumption.
Furthermore, if that ever does change, the right solution is
not to prevent commit from completing, but to set EDITOR to
a script that will record the contents we see. After all,
the point of these tests is to check what the user sees in
their EDITOR, so that would be the most direct test. For
now, though, we can continue to use the "shortcut" that
COMMIT_EDITMSG is left intact.

One of the tests tries to ensure that editor is not run due
to an early failure. However, it needs to quote the pathname
of the trash directory used in $GIT_EDITOR, since git will
pass it along to the shell. In other words, the test would
pass whether the code was correct or not, since the unquoted
editor specification would never run.

We never noticed the problem because the code is indeed

be8779f7ac git-submodule: work with GIT_DIR/GIT_WORK_TREE
The combination of GIT_DIR and GIT_WORK_TREE can be used to manage
files in one directory hierarchy while keeping the repository that
keeps track of them outside the directory hierarchy.  For example:

    git init --bare /path/to/there
    alias dotfiles="GIT_DIR=/path/to/there GIT_WORK_TREE=/path/to/here git"

    cd /path/to/here
    dotfiles add file
    dotfiles commit -a -m "add /path/to/here/file"
    ...

lets you manage files under /path/to/here/ in the repository located
at /path/to/there.

git-submodule however fails to add submodules, as it is confused by
GIT_DIR and GIT_WORK_TREE environment variables when it tries to
work in the submodule, like so:

    dotfiles submodule add http://path.to/submodule
    fatal: working tree '/path/to/here' already exists.

Simply unsetting the environment where the command works on the
submodule is sufficient to fix this, as it has set things up so
that GIT_DIR and GIT_WORK_TREE do not even have to point at the
repository and the working tree of the submodule.

f628825481 t/lib-httpd: handle running under --valgrind
Running the http tests with valgrind does not work for two
reasons:

  1. Apache complains about following the symbolic link from

  2. Apache does not pass through the GIT_VALGRIND variable
     to the backend CGI.

This patch fixes both problems. Unfortunately, there is a
slight hack we need to handle passing environment variables
through Apache. If we just tell it:

  PassEnv GIT_VALGRIND

then Apache will complain when GIT_VALGRIND is not set. If
we try:

  SetEnv GIT_VALGRIND ${GIT_VALGRIND}

then when GIT_VALGRIND is not set, it will pass through the
literal "${GIT_VALGRIND}". Instead, we now unconditionally
pass through GIT_VALGRIND from lib-httpd.sh into apache,
even if it is empty.

back to checking XDG config, which is usually
$HOME/.config/git/attributes.

However, if $HOME is unset, then home_config_paths will return
NULL, and we end up calling fopen(NULL).

Depending on your system, this may or may not cause the
accompanying test to fail (e.g., on Linux and glibc, the
address will go straight to open, which will return EFAULT).
However, valgrind will reliably notice the error.

Now that git respects XDG_CONFIG_HOME for some lookups, we

c12f82ae63 diff: test precedence of external diff drivers
There are three ways to specify an external diff command:
GIT_EXTERNAL_DIFF in the environment, diff.external in the
config, or a "diff" gitattribute. The current order of
precedence is:

  1. gitattribute

  2. GIT_EXTERNAL_DIFF

  3. diff.external

Usually our rule is that environment variables should take
precedence over on-disk config (i.e., option 2 should come
before option 1). However, this situation is trickier than
some, because option 1 is more specific to the individual
file than option 2 (which affects all files), so it might be
preferable. So the current behavior can be seen as
implementing "do the specific thing if we can, but fall back
to this general thing".

This is probably not what we would do if we were writing git
from scratch, but it has been this way for several years,
and is not worth changing. So let's at least document that
this is the way it's supposed to work with a test.

While we're there, let's also make sure that diff.external
(which was not previously tested at all) works by running it
through the same tests as GIT_EXTERNAL_DIFF.

bd8c1a9b49 diff: correctly disable external_diff with --no-ext-diff
Upon seeing a type-change filepair, "diff --no-ext-diff" does not
show the usual "deletion followed by addition" split patch and does
not run the external diff driver either.

This is because the logic to disable external diff was placed at a
wrong level in the callchain.  run_diff_cmd() decides to show the
split patch only when external diff driver is not configured or
specified via GIT_EXTERNAL_DIFF environment, but this is done before
checking if --no-ext-diff was given.  To make things worse,
run_diff_cmd() checks --no-ext-diff and disables the output for such
a filepair completely, as the callchain below it (e.g. builtin_diff)
does not want to handle typechange filepairs.

9aab1b5118 commit-tree: resurrect command line parsing updates
79a9312 (commit-tree: update the command line parsing, 2011-11-09)
updated the command line parser to understand the usual "flags first
and then non-flag arguments" order, in addition to the original and
a bit unusual "tree comes first and then zero or more -p <parent>".

Unfortunately, ba3c69a (commit: teach --gpg-sign option, 2011-10-05)
broke it by mistake.  Resurrect it, and protect the feature with a
test from future breakages.

66fd93ee06 t4012: use 'printf' instead of 'dd' to generate a binary file
For some reason, 'echo X | dd bs=1k seek=1' creates a file with 2050 bytes
on Windows instead of the expected 1026 bytes, so that a test fails. Since
the actual contents of the file are irrelevant as long as there is at
least one zero byte so that the diff machinery recognizes it as binary,
use printf to generate it.
