* clone: Allow repo using gitfile as a referenceAaron Schrab2013-04-09
| | | | | | | | | | Try reading gitfile files when processing --reference options to clone. This will allow, among other things, using a submodule checked out with a recent version of git as a reference repository without requiring the user to have internal knowledge of submodule layout.

* do not use GIT_TRACE_PACKET=3 in testsJeff King2013-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* upload-pack: remove packet debugging harnessJeff King2013-02-20
| | | | | | | | | | | | | | | 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.

* everything_local(): mark alternate refs as completeMichael Haggerty2012-02-12

* refs: loosen over-strict "format" checkJunio C Hamano2011-11-16
| | | | | | | | | | | | | | | | | 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.

* tests: use "test_cmp", not "diff", when verifying the resultGary V. Vaughan2010-05-31
| | | | | | | | | | | In tests, call test_cmp rather than raw diff where possible (i.e. if the output does not go to a pipe), to allow the use of, say, 'cmp' when the default 'diff -u' is not compatible with a vendor diff. When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS. Signed-off-by: Gary V. Vaughan <gary@thewrittenword.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * Add test for cloning with "--reference" repo being a subset of source repoJohan Herland2008-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Fix tests breaking when checkout path contains shell metacharactersBryan Donlan2008-05-05
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <bdonlan@fushizen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* fetch: if not fetching from default remote, ignore default mergeJohannes Schindelin2007-10-16
| | | | | | | | | | | | | | | | | 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. Incidentally, this unconvered a bug in our own test suite, where "git pull <some-path>" was expected to merge the ref given in the defaults, even if not pulling from the default remote.

* git-clone: aggressively optimize local clone behaviour.Junio C Hamano2007-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <gitster@pobox.com>
* git-clone --reference: saner handling of borrowed symrefs.Junio C Hamano2007-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "prune: --grace=time"Junio C Hamano2007-01-21
| | | | | | | | | | 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.
* prune: --grace=timeMatthias Lederhofer2007-01-20
