Jeff King	125a05fd0b	clone: drop connectivity check for local clones Commit `0433ad1` (clone: run check_everything_connected, 2013-03-25) added the same connectivity check to clone that we use for fetching. The intent was to provide enough safety checks that "git clone git://..." could be counted on to detect bit errors and other repo corruption, and not silently propagate them to the clone. For local clones, this turns out to be a bad idea, for two reasons: 1. Local clones use hard linking (or even shared object stores), and so complete far more quickly. The time spent on the connectivity check is therefore proportionally much more painful. 2. Local clones do not actually meet our safety guarantee anyway. The connectivity check makes sure we have all of the objects we claim to, but it does not check for bit errors. We will notice bit errors in commits and trees, but we do not load blob objects at all. Whereas over the pack transport, we actually recompute the sha1 of each object in the incoming packfile; bit errors change the sha1 of the object, which is then caught by the connectivity check. This patch drops the connectivity check in the local case. Note that we have to revert the changes from `0433ad1` to t5710, as we no longer notice the corruption during clone. We could go a step further and provide a "verify even local clones" option, but it is probably not worthwhile. You can already spell that as "cd foo.git && git fsck && git clone ." or as "git clone --no-local foo.git".

Jeff King	0433ad128c	clone: run check_everything_connected When we fetch from a remote, we do a revision walk to make sure that what we received is connected to our existing history. We do not do the same check for clone, which should be able to check that we received an intact history graph. The upside of this patch is that it will make clone more resilient against propagating repository corruption. The downside is that we will now traverse "rev-list --objects --all" down to the roots, which may take some time (it is especially noticeable for a "--local --bare" clone). Note that we need to adjust t5710, which tries to make such a bogus clone. Rather than checking after the fact that our clone is bogus, we can simplify it to just make sure "git clone" reports failure.

Jeff King	0aac7bb287	clone: die on errors from unpack_trees When clone is populating the working tree, it ignores the return status from unpack_trees; this means we may report a successful clone, even when the checkout fails. When checkout fails, we may want to leave the $GIT_DIR in place, as it might be possible to recover the data through further use of "git checkout" (e.g., if the checkout failed due to a transient error, disk full, etc). However, we already die on a number of other checkout-related errors, so this patch follows that pattern. In addition to marking a now-passing test, we need to adjust t5710, which blindly assumed it could make bogus clones of very deep alternates hierarchies. By using "--bare", we can avoid it actually touching any objects. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago

Bryan Donlan	f69e836fab	Fix tests breaking when checkout path contains shell metacharacters 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>	17 years ago
Junio C Hamano	41ac414ea2	Sane use of test_expect_failure Originally, test_expect_failure was designed to be the opposite of test_expect_success, but this was a bad decision. Most tests run a series of commands that leads to the single command that needs to be tested, like this: test_expect_{success,failure} 'test title' ' setup1 && setup2 && setup3 && what is to be tested ' And expecting a failure exit from the whole sequence misses the point of writing tests. Your setup$N that are supposed to succeed may have failed without even reaching what you are trying to test. The only valid use of test_expect_failure is to check a trivial single command that is expected to fail, which is a minority in tests of Porcelain-ish commands. This large-ish patch rewrites all uses of test_expect_failure to use test_expect_success and rewrites the condition of what is tested, like this: test_expect_success 'test title' ' setup1 && setup2 && setup3 && ! this command should fail ' test_expect_failure is redefined to serve as a reminder that that test should succeed but due to a known breakage in git it currently does not pass. So if git-foo command should create a file 'bar' but you discovered a bug that it doesn't, you can write a test like this: test_expect_failure 'git-foo should create bar' ' rm -f bar && git foo && test -f bar ' This construct acts similar to test_expect_success, but instead of reporting "ok/FAIL" like test_expect_success does, the outcome is reported as "FIXED/still broken".

Alex Riesen	9288bedafa	Make t5710 more strict when creating nested repos The test 'creating too deep nesting' can fail even when cloning the repos, but is not its main purpose (it has to prepare nested repos and ensure the last one is invalid). So split the test into the creation and invalidity checking parts. Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Junio C Hamano	a6080a0a44	War on whitespace This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

Junio C Hamano	026aa93818	Revert "prune: --grace=time" This reverts commit `9b088c4e39`. 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.	18 years ago
Matthias Lederhofer	9b088c4e39	prune: --grace=time This option gives grace period to objects that are unreachable from the refs from getting pruned.

Junio C Hamano	171e800b37	Revert "fix testsuite: make sure they use templates freshly built from the source" This reverts commit `74d20040ca`. Version from Johannes to introduce GIT_TEMPLATE_DIR is simpler, although I unconsciously stayed away from introducing yet another environment variable.	18 years ago
Junio C Hamano	74d20040ca	fix testsuite: make sure they use templates freshly built from the source The initial t/trash repository for testing was created properly but over time we gained many tests that create secondary test repositories with init-db or clone and they were not careful enough. This fixes it. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	2c6d22df9f	t5710: fix two thinkos. The intention of the test seems to be to build a long chain of clones that locally borrow objects from their parents and see the system give up dereferencing long chains. There were two problems: (1) it did not test the right repository; (2) it did not build a chain long enough to trigger the limitation. I do not think it is a good test to make sure the limitation the current implementation happens to have still exists, but that is a topic at a totally different level. At least this fixes the broken test. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
