2012-08-10git svn: reset invalidates the memoized mergeinfo cachesLibravatar Peter Baumann1-0/+78
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Sadly, this is where the behavior has regressed: git svn reset doesn't invalidate the old mergeinfo cache, which is no longer valid for the reimport, which leads to 'm' beeing imprted with only 'c' as parent.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 68f532f4ba888 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.

2012-08-10git svn: handle errors and concurrent commits in dcommitLibravatar Robert Luberda1-0/+216
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. Signed-off-by: Eric Wong <normalperson@yhbt.net>

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.

2012-07-29t1100-*.sh: Fix an intermittent test failureLibravatar Ramsay Jones1-0/+1
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. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-07-26t7502: test early quit from commit with bad identLibravatar Jeff King1-0/+17
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.

2012-07-26t7502: handle systems where auto-identity is brokenLibravatar Jeff King1-3/+10
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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-07-26t7502: drop confusing test_might_fail callLibravatar Jeff King1-1/+1
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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

2012-07-25git-submodule: work with GIT_DIR/GIT_WORK_TREELibravatar Daniel Graña1-0/+61
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.

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.

2012-07-17diff: correctly disable external_diff with --no-ext-diffLibravatar Junio C Hamano1-0/+19
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.

2012-07-17commit-tree: resurrect command line parsing updatesLibravatar Junio C Hamano1-0/+17
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.

Make the code less bulky and easier to read. Also do not overlook failures like e.g. git failing because of unexpected signals. Signed-off-by: Alexander Strasser <eclipse7@gmx.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-07-16t4012: use 'printf' instead of 'dd' to generate a binary fileLibravatar Johannes Sixt1-1/+1
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.
