Stephan Beyer	d492b31caf	t/: Use "test_must_fail git" instead of "! git" This patch changes every occurrence of "! git" -- with the meaning that a git call has to gracefully fail -- into "test_must_fail git". This is useful to - make sure the test does not fail because of a signal, e.g. SIGSEGV, and - advertise the use of "test_must_fail" for new tests.

Jeff King	d1a4489a56	avoid null SHA1 in oldest reflog When the user specifies a ref by a reflog entry older than one we have (e.g., "HEAD@{20 years ago"}), we issue a warning and give them the "from" value of the oldest reflog entry. That is, we say "we don't know what happened before this entry, but before this we know we had some particular SHA1". However, the oldest reflog entry is often a creation event such as clone or branch creation. In this case, the entry claims that the ref went from "00000..." (the null sha1) to the new value, and the reflog lookup returns the null sha1. While this is technically correct (the entry tells us that the ref didn't exist at the specified time) it is not terribly useful to the end user. What they probably want instead is "the oldest useful sha1 that this ref ever had". This patch changes the behavior such that if the oldest ref would return the null sha1, it instead returns the first value the ref ever had. We never discovered this problem in the test scripts because we created "fake" reflogs that had only a specified segment of history. This patch updates the tests with a creation event at the beginning of history. Signed-off-by: Jeff King <peff@peff.net> Acked-by: Shawn O.

Karl Hasselström	3fe8dce6fc	Make old sha1 optional with git update-ref -d Giving the old sha1 is already optional when changing a ref, and it's quite handy when running update-ref manually. So make it optional for deleting a ref too. Signed-off-by: Karl Hasselström <kha@treskal.com> 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".

Linus Torvalds	c3b0dec509	Be more careful about updating refs This makes write_ref_sha1() more careful: it actually checks the SHA1 of the ref it is updating, and refuses to update a ref with an object that it cannot find. Perhaps more importantly, it also refuses to update a branch head with a non-commit object. I don't quite know how the stable series maintainers were able to corrupt their repository to have a HEAD that pointed to a tag rather than a commit object, but they did. Which results in a totally broken repository that cannot be cloned or committed on. So make it harder for people to shoot themselves in the foot like that. The test t1400-update-ref.sh is fixed at the same time, as it assumed that the commands involved in the particular test would not care about corrupted repositories whose refs point at nonexistant bogus objects. That assumption does not hold true anymore. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Alex Riesen	d9c8344b46	stop t1400 hiding errors in tests The last rm in the test was lacking an "&&" before it, which caused the errors in the commands be silently hidden. Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Shawn O. Pearce	432e93a164	Cleanup unnecessary file modifications in t1400-update-ref Kristian Høgsberg pointed out that the two file modifications we were doing during the 'creating initial files' step are not even used within the test suite. This was actually confusing as we do not even need these changes for the tests to pass. All that really matters here is the specific commit dates are used so that these appear in the branch's reflog, and that the dates are different so that the branch will update when asked and the reflog entry is also updated. There is no need for the file modification. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago

Junio C Hamano	16d7cc90dd	Extend read_ref_at() to be usable from places other than sha1_name. You can pass an extra argument to the function to receive the reflog message information. Also when the log does not go back beyond the point the user asked, the cut-off time and count are given back to the caller for emitting the error messages as appropriately. We could later add configuration for get_sha1_basic() to make it an error instead of it being just a warning. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Shawn O. Pearce	0bee591869	Enable reflogs by default in any repository with a working directory. New and experienced Git users alike are finding out too late that they forgot to enable reflogs in the current repository, and cannot use the information stored within it to recover from an incorrectly entered command such as `git reset --hard HEAD^^^` when they really meant HEAD^^ (aka HEAD~2). So enable reflogs by default in all future versions of Git, unless the user specifically disables it with: [core] logAllRefUpdates = false in their .git/config or ~/.gitconfig. We only enable reflogs in repositories that have a working directory associated with them, as shared/bare repositories do not have an easy means to prune away old log entries, or may fail logging entirely if the user's gecos information is not valid during a push. This heuristic was suggested on the mailing list by Junio. Documentation was also updated to indicate the new default behavior. We probably should start to teach usuing the reflog to recover from mistakes in some of the tutorial material, as new users are likely to make a few along the way and will feel better knowing they can recover from them quickly and easily, without fsck-objects' lost+found features.

Junio C Hamano	ef176ad06a	Fix t1400-update-ref test minimally It depended on specific error messages to detect failure but the implementation changed and broke the test. This fixes the breakage minimally. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	8aac4b45f3	t1400: make test debuggable. I had a hard time figuring out why this test was failing with the packed-refs update without running it under "sh -x". This makes output from "sh t1400-update-ref.sh -v" more descriptive. Updating other tests would be a good janitorial task. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Shawn Pearce	818f477c40	Display an error from update-ref if target ref name is invalid. Alex Riesen (raa.lkml@gmail.com) recently observed that git branch would fail with no error message due to unexpected situations with regards to refs. For example, if .git/refs/heads/gu is a file but "git branch -b refs/heads/gu/fixa HEAD" was invoked by the user it would fail silently due to refs/heads/gu being a file and not a directory. This change adds a test for trying to create a ref within a directory that is actually currently a file, and adds error printing within the ref locking routine should the resolve operation fail. The error printing code probably belongs at this level of the library as other failures within the ref locking, writing and logging code are also currently at this level of the code.

Shawn Pearce	a3a733e63b	Record the type of commit operation in the reflog. If committing a merge (.git/MERGE_HEAD exists), an initial tree (no HEAD) or using --amend to amend the prior commit then denote the subtype of commit in the reflog. This helps to distinguish amended or merge commits from normal commits. In the case of --amend the prior sha1 is probably the commit which is being thrown away in favor of the new commit. Since it is likely that the old commit doesn't have any ref pointing to it anymore it can be interesting to know why that the commit was replaced and orphaned. In the case of a merge the prior sha1 is probably the first parent of the new merge commit. Consequently having its prior sha1 in the reflog is slightly less interesting but its still informative to know the commit was the result of a merge which had to be completed by hand.

Shawn Pearce	cce91a2cae	Change 'master@noon' syntax to 'master@{noon}'. Its ambiguous to parse "master@2006-05-17 18:30:foo" when foo is meant as a file name and ":30" is meant as 30 minutes past 6 pm. Therefore all date specifications in a sha1 expression must now appear within brackets and the ':' splitter used for the path name in a sha1 expression ignores ':' appearing within brackets.

Shawn Pearce	e52290428b	General ref log reading improvements. Corrected the log starting time displayed in the error message (as it was always showing the epoch due to a bad input to strtoul). Improved the log parser so we only scan backwards towards the '\n' from the end of the prior log; during this scan the last '>' is remembered to improve performance (rather than scanning forward to it). If the log record matched is the last log record in the file only use its new sha1 value if the date matches exactly; otherwise we leave the passed in sha1 alone as it already contains the current value of the ref. This way lookups of dates later than the log end to stick with the current ref value in case the ref was updated without logging. If it looks like someone changed the ref without logging it and we are going to return the sha1 which should have been valid during the missing period then warn the user that there might be log data missing and thus their query result may not be accurate. The check isn't perfect as its just based on comparing the old and new sha1 values between the two log records but its better than not checking at all. Implemented test cases based on git-rev-parse for most of the boundary conditions. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Shawn Pearce	6de08ae688	Log ref updates to logs/refs/<ref> If config parameter core.logAllRefUpdates is true or the log file already exists then append a line to ".git/logs/refs/<ref>" whenever git-update-ref <ref> is executed. Each log line contains the following information: oldsha1 <SP> newsha1 <SP> committer <LF> where committer is the current user, date, time and timezone in the standard GIT ident format. If the caller is unable to append to the log file then git-update-ref will fail without updating <ref>. An optional message may be included in the log line with the -m flag. Signed-off-by: Shawn O.
