2016-03-16clone tests: rename t57* => t56*Stefan Beller
When trying to find a good spot for testing clone with submodules, I got confused where to add a new test file. There are both tests in t560* as well as t57* both testing the clone command. t/README claims the second digit is to indicate the command, which is inconsistent to the current naming structure. Rename all t57* tests to be in t56* to follow the pattern of the digits as laid out in t/README. It would have been less work to rename t56* => t57* because there are less files, but the tests in t56* look more basic and I assumed the higher the last digits the more complicated niche details are tested, so with the patch now it looks more in order to me.

2015-10-22clone: allow "--dissociate" without referenceAlex Riesen
The "--reference" option is not the only way to provide a repository to borrow objects from. A repository that borrows from another repository can be cloned with "clone --local" and the resulting repository will borrow from the same repository, which the user may want to "--dissociate" from.

2015-10-15Merge branch 'js/clone-dissociate'Junio C Hamano
"git clone --dissociate" runs a big "git repack" process at the end, and it helps to close file descriptors that are open on the packs and their idx files before doing so on filesystems that cannot remove a file that is still open. * js/clone-dissociate: clone --dissociate: avoid locking pack files sha1_file.c: add a function to release all packs sha1_file: consolidate code to close a pack's file descriptor t5700: demonstrate a Windows file locking issue with `git clone --dissociate`
2015-10-07clone --dissociate: avoid locking pack filesJohannes Schindelin
When `git clone` is asked to dissociate the repository from the reference repository whose objects were used, it is quite possible that the pack files need to be repacked. In that case, the pack files need to be deleted that were originally hard-links to the reference repository's pack files. On platforms where a file cannot be deleted if another process still holds a handle on it, we therefore need to take pains to release all pack files and indexes before dissociating. This fixes The test case to demonstrate the breakage technically does not need to be run on Linux or MacOSX. It won't hurt, either, though.

2015-08-10add_to_alternates_file: don't add duplicate entriesJeff King
The add_to_alternates_file function blindly uses hold_lock_file_for_append to copy the existing contents, and then adds the new line to it. This has two minor problems: 1. We might add duplicate entries, which are ugly and inefficient. 2. We do not check that the file ends with a newline, in which case we would bogusly append to the final line. This is quite unlikely in practice, though, as we call this function only from git-clone, so presumably we are the only writers of the file (and we always add a newline). Instead of using hold_lock_file_for_append, let's copy the file line by line, which ensures all records are properly terminated. If we see an extra line, we can simply abort the update (there is no point in even copying the rest, as we know that it would be identical to the original). As a bonus, we also get rid of some calls to the static-buffer mkpath and git_path functions. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2015-08-10t5700: modernize styleJeff King
The early part of this test is rather old, and does not follow our usual style guidelines. In particular: - the tests liberally chdir, and expect out-of-test "cd" commands to return them to a sane state - test commands aren't indented at all - there are a lot of minor formatting nits, like the opening quote of the test block on the wrong line, spaces after ">", etc This patch fixes the style issues, and uses a few helper functions, along with subshells and "git -C", to avoid changing the cwd of the main script.

2014-10-15clone: --dissociate option to mark that reference is only temporaryJunio C Hamano
While use of the --reference option to borrow objects from an existing local repository of the same project is an effective way to reduce traffic when cloning a project over the network, it makes the resulting "borrowing" repository dependent on the "borrowed" repository. After running git clone --reference=P $URL Q the resulting repository Q will be broken if the borrowed repository P disappears. The way to allow the borrowed repository to be removed is to repack the borrowing repository (i.e. run "git repack -a -d" in Q); while power users may know it very well, it is not easily discoverable. Teach a new "--dissociate" option to "git clone" to run this repacking for the user. Helped-by: Johannes Sixt <> Signed-off-by: Junio C Hamano <>

2013-03-21do not use GIT_TRACE_PACKET=3 in testsJeff King
Some test scripts use the GIT_TRACE mechanism to dump debugging information to descriptor 3 (and point it to a file using the shell). On Windows, however, bash is unable to set up descriptor 3. We do not write our trace to the file, and worse, we may interfere with other operations happening on descriptor 3, causing tests to fail or even behave inconsistently. Prior to commit 97a83fa (upload-pack: remove packet debugging harness), these tests used GIT_DEBUG_SEND_PACK, which only supported output to a descriptor. The tests in t5503 were always broken on Windows, and were marked to be skipped via the NOT_MINGW prerequisite. In t5700, the tests used to pass prior to 97a83fa, but only because they were not careful enough; because we only grepped the trace file, an empty file looked successful to us. But post-97a83fa, the writing to descriptor 3 causes "git fetch" to hang (presumably because we are throwing random bytes into the middle of the protocol). Now that we are using the GIT_TRACE mechanism, we can improve both scripts by asking git to write directly to a file rather than a descriptor. That fixes the hang in t5700, and should allow t5503 to successfully run on Windows. In both cases we now also use "test -s" to double-check that our trace file actually contains output, which should reduce the possibility of an erroneously passing test.

2013-02-20upload-pack: remove packet debugging harnessJeff King
If you set the GIT_DEBUG_SEND_PACK environment variable, upload-pack will dump lines it receives in the receive_needs phase to a descriptor. This debugging harness is a strict subset of what GIT_TRACE_PACKET can do. Let's just drop it in favor of that. A few tests used GIT_DEBUG_SEND_PACK to confirm which objects get sent; we have to adapt them to the new output format. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>

2011-11-17refs: loosen over-strict "format" checkJunio C Hamano
The add_extra_ref() interface is used to add an extra-ref that is _not_ our ref for the purpose of helping auto-following of tags and reducing object transfer from remote repository, and they are typically formatted as a tagname followed by ^{} to make sure no valid refs match that pattern. In other words, these entries are deliberately formatted not to pass check-refname-format test. A recent series however added a test unconditionally to the add_ref() function that is called from add_extra_ref(). The check may be sensible for other two callsites of the add_ref() interface, but definitely is a wrong thing to do in add_extra_ref(). Disable it.

2008-05-23Add test for cloning with "--reference" repo being a subset of source repoJohan Herland
The first test in this series tests "git clone -l -s --reference B A C", where repo B is a superset of repo A (A has one commit, B has the same commit plus another). In this case, all objects to be cloned are already present in B. However, we should also test the case where the "--reference" repo is a _subset_ of the source repo (e.g. "git clone -l -s --reference A B C"), i.e. some objects are not available in the "--reference" repo, and will have to be found in the source repo.

In this case, the reference repository has some useful loose objects, but not all useful objects, and we make sure that we can find the objects we fetch from the repository we're cloning in the new repository, instead of potentially being distracted by the reference repository. Doing the wrong thing in a builtin-clone implementation would lead to this looking for an object in the wrong place, not finding it (because it's only in the right place), and crashing.

2008-05-05Fix tests breaking when checkout path contains shell metacharactersBryan Donlan
This fixes the remainder of the issues where the test script itself is at fault for failing when the git checkout path contains whitespace or other shell metacharacters. The majority of git svn tests used the idiom test_expect_success "title" "test script using $svnrepo" These were changed to have the test script in single-quotes: test_expect_success "title" 'test script using "$svnrepo"' which unfortunately makes the patch appear larger than it really is. One consequence of this change is that in the verbose test output the value of $svnrepo (and in some cases other variables, too) is no longer expanded, i.e. previously we saw * expecting success: test script using /path/to/git/t/trash/svnrepo but now it is: * expecting success: test script using "$svnrepo" Signed-off-by: Bryan Donlan <> Signed-off-by: Junio C Hamano <>
2007-10-16fetch: if not fetching from default remote, ignore default mergeJohannes Schindelin
When doing "git fetch <remote>" on a remote that does not have the branch referenced in branch.<current-branch>.merge, git fetch failed. It failed because it tried to add the "merge" ref to the refs to be fetched. Fix that. And add a test case.

2007-08-02git-clone: aggressively optimize local clone behaviour.Junio C Hamano
This changes the behaviour of cloning from a repository on the local machine, by defaulting to "-l" (use hardlinks to share files under .git/objects) and making "-l" a no-op. A new option, --no-hardlinks, is also added to cause file-level copy of files under .git/objects while still avoiding the normal "pack to pipe, then receive and index pack" network transfer overhead. The old behaviour of local cloning without -l nor -s is availble by specifying the source repository with the newly introduced file:///path/to/repo.git/ syntax (i.e. "same as network" cloning). * With --no-hardlinks (i.e. have all .git/objects/ copied via cpio) would not catch the source repository corruption, and also risks corrupted recipient repository if an alpha-particle hits memory cell while indexing and resolving deltas. As long as the recipient is created uncorrupted, you have a good back-up. * same-as-network is expensive, but it would catch the breakage of the source repository. It still risks corrupted recipient repository due to hardware failure. As long as the recipient is created uncorrupted, you have a good back-up. * The new default on the same filesystem, as long as the source repository is healthy, it is very likely that the recipient would be, too. Also it is very cheap. You do not get any back-up benefit, though. None of the method is resilient against the source repository corruption, so let's discount that from the comparison. Then the difference with and without --no-hardlinks matters primarily if you value the back-up benefit or not. If you want to use the cloned repository as a back-up, then it is cheaper to do a clone with --no-hardlinks and two git-fsck (source before clone, recipient after clone) than same-as-network clone, especially as you are likely to do a git-fsck on the recipient if you are so paranoid anyway. Which leads me to believe that being able to use file:/// is probably a good idea, if only for testability, but probably of little practical value. We default to hardlinked clone for everyday use, and paranoids can use --no-hardlinks as a way to make a back-up. Signed-off-by: Junio C Hamano <>
2007-02-04git-clone --reference: saner handling of borrowed symrefs.Junio C Hamano
When using --reference to borrow objects from a neighbouring repository while cloning, we copy the entire set of refs under temporary "refs/reference-tmp/refs" space and set up the object alternates. However, a textual symref copied this way would not point at the right place, and causes later steps to emit error messages (which is harmless but still alarming). This is most visible when using a clone created with the separate-remote layout as a reference, because such a repository would have refs/remotes/origin/HEAD with 'ref: refs/remotes/origin/master' as its contents. Although we do not create symbolic-link based refs anymore, they have the same problem because they are always supposed to be relative to refs/ hierarchy (we dereference by hand, so it only is good for HEAD and nothing else). In either case, the solution is simply to remove them after copying under refs/reference-tmp; if a symref points at a true ref, that true ref itself is enough to ensure that objects reachable from it do not needlessly get fetched.

This reverts commit 9b088c4e394df84232cfd37aea78349a495b09c1. Protecting 'mature' objects does not make it any safer. We should admit that git-prune is inherently unsafe when run in parallel with other operations without involving unwarranted locking overhead, and with the latest git, even rebase and reset would not immediately create crufts anyway.
