2014-10-15test: put tests for handling of bad ref names in one placeLibravatar Ronnie Sahlberg1-44/+0
There's no straightforward way to grep for all tests dealing with invalid refs. Put them in a single test script so it is easy to see what functionality has not been exercised with bad ref names yet.

2014-10-15branch -d: avoid repeated symref resolutionLibravatar Jonathan Nieder1-0/+34
If a repository gets in a broken state with too much symref nesting, it cannot be repaired with "git branch -d": $ git symbolic-ref refs/heads/nonsense refs/heads/nonsense $ git branch -d nonsense error: branch 'nonsense' not found. Worse, "git update-ref --no-deref -d" doesn't work for such repairs either: $ git update-ref -d refs/heads/nonsense error: unable to resolve reference refs/heads/nonsense: Too many levels of symbolic links Fix both by teaching resolve_ref_unsafe a new RESOLVE_REF_NO_RECURSE flag and passing it when appropriate. Callers can still read the value of a symref (for example to print a message about it) with that flag set --- resolve_ref_unsafe will resolve one level of symrefs and stop there.

2014-06-03refs.c: change read_ref_at to use the reflog iteratorsLibravatar Ronnie Sahlberg1-2/+2
read_ref_at has its own parsing of the reflog file for no really good reason so lets change this to use the existing reflog iterators. This removes one instance where we manually unmarshall the reflog file format. Remove the now redundant ref_msg function. Log messages for errors are changed slightly. We no longer print the file name for the reflog, instead we refer to it as 'Log for ref <refname>'. This might be a minor useability regression, but I don't really think so, since experienced users would know where the log is anyway and inexperienced users would not know what to do about/how to repair 'Log ... has gap ...' anyway. Adapt the t1400 test to handle the change in log messages. Signed-off-by: Ronnie Sahlberg <sahlberg@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This case wants to test passing a bad refname to the "update" command. But it also passes too few arguments to "update", which muddles the situation: which error should be diagnosed?

2014-04-07update-ref --stdin -z: deprecate interpreting the empty string as zerosLibravatar Michael Haggerty1-2/+3
In the original version of this command, for the single case of the "update" command's <newvalue>, the empty string was interpreted as being equivalent to 40 "0"s. This shorthand is unnecessary (binary input will usually be generated programmatically anyway), and it complicates the parser and the documentation. So gently deprecate this usage: remove its description from the documentation and emit a warning if it is found. But for reasons of backwards compatibility, continue to accept it.

2014-04-07update-ref.c: extract a new function, parse_next_sha1()Libravatar Michael Haggerty1-1/+1
Replace three functions, update_store_new_sha1(), update_store_old_sha1(), and parse_next_arg(), with a single function, parse_next_sha1(). The new function takes care of a whole argument, including checking whether it is there, converting it to an SHA-1, and emitting errors on EOF or for invalid values. The return value indicates whether the argument was present or absent, which requires a bit of intelligence because absent values are represented differently depending on whether "-z" was used. The new interface means that the calling functions, parse_cmd_*(), don't have to interpret the result differently based on the line_termination mode that is in effect. It also means that parse_cmd_create() can distinguish unambiguously between an empty new value and a zeros new value, which fixes a failure in t1400.

2014-04-07parse_arg(): really test that argument is properly terminatedLibravatar Michael Haggerty1-2/+2
The old parse_arg(), when fed an argument "refs/heads/a"master parsed 'refs/heads/a' off of the front of the argument and considered itself successful. It was only when parse_next_arg() tried to parse the *next* argument that a problem was noticed. But in fact, the definition of the input format requires arguments to be terminated by SP or NUL, so *this* argument is already erroneous and parse_arg() should diagnose the problem. So teach parse_arg() to verify that C-quoted arguments are terminated correctly. If not, emit a more specific error message. There is no corresponding error case of a non-C-quoted argument that is not terminated correctly, because the end of a non-quoted argument is *by definition* a space or NUL, so there is no way to insert other junk between the "end" of the argument and the argument terminator. Adjust the tests to expect the new error message. Add a docstring to the function, incorporating the comments that were formerly within the function plus some added information.

So rename the test s/zero/empty/, and change the expected error from fatal: create $c given zero new value to fatal: create $c missing <newvalue> Of course, this makes the test fail now, because although "git update-ref" tries to distinguish between these two errors, it does not succeed in this situation.

2008-07-08avoid null SHA1 in oldest reflogLibravatar Jeff King1-1/+8
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.

2008-02-01Sane use of test_expect_failureLibravatar Junio C Hamano1-12/+12
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".

2008-01-16Be more careful about updating refsLibravatar Linus Torvalds1-6/+13
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.

2006-12-15Enable reflogs by default in any repository with a working directory.Libravatar Shawn O. Pearce1-2/+2
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.

2006-07-28Display an error from update-ref if target ref name is invalid.Libravatar Shawn Pearce1-0/+12
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.

2006-07-10Record the type of commit operation in the reflog.Libravatar Shawn Pearce1-3/+16
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.

2006-05-19General ref log reading improvements.Libravatar Shawn Pearce1-0/+64
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>
