2014-01-23repack: propagate pack-objects options as stringsLibravatar Jeff King1-11/+11
In the original shell version of git-repack, any options destined for pack-objects were left as strings, and passed as a whole. Since the C rewrite in commit a1bbc6c (repack: rewrite the shell script in C, 2013-09-15), we now parse these values to integers internally, then reformat the integers when passing the option to pack-objects. This has the advantage that we catch format errors earlier (i.e., when repack is invoked, rather than when pack-objects is invoked). It has three disadvantages, though: 1. Our internal data types may not be the right size. In the case of "--window-memory" and "--max-pack-size", these are "unsigned long" in pack-objects, but we can only represent a regular "int". 2. Our parsing routines might not be the same as those of pack-objects. For the two options above, pack-objects understands "100m" to mean "100 megabytes", but repack does not. 3. We have to keep a sentinel value to know whether it is worth passing the option along. In the case of "--window-memory", we currently do not pass it if the value is "0". But that is a meaningful value to pack-objects, where it overrides any configured value. We can fix all of these by simply passing the strings from the user along to pack-objects verbatim. This does not actually fix anything for "--depth" or "--window", but these are converted, too, for consistency.

2014-01-02gc: notice gc processes run by other usersLibravatar Kyle J. McKay1-1/+1
Since 64a99eb4 git gc refuses to run without the --force option if another gc process on the same repository is already running. However, if the repository is shared and user A runs git gc on the repository and while that gc is still running user B runs git gc on the same repository the gc process run by user A will not be noticed and the gc run by user B will go ahead and run. The problem is that the kill(pid, 0) test fails with an EPERM error since user B is not allowed to signal processes owned by user A (unless user B is root). Update the test to recognize an EPERM error as meaning the process exists and another gc should not be run (unless --force is given). Signed-off-by: Kyle J.

2013-12-27Remove the line length limit for graft filesLibravatar Johannes Schindelin1-4/+4
Support for grafts predates Git's strbuf, and hence it is understandable that there was a hard-coded line length limit of 1023 characters (which was chosen a bit awkwardly, given that it is *exactly* one byte short of aligning with the 41 bytes occupied by a commit name and the following space or new-line character). While regular commit histories hardly win comprehensibility in general if they merge more than twenty-two branches in one go, it is not Git's business to limit grafts in such a way. In this particular developer's case, the use case that requires substantially longer graft lines to be supported is the visualization of the commits' order implied by their changes: commits are considered to have an implicit relationship iff exchanging them in an interactive rebase would result in merge conflicts. Thusly implied branches tend to be very shallow in general, and the resulting thicket of implied branches is usually very wide; It is actually quite common that *most* of the commits in a topic branch have not even one implied parent, so that a final merge commit has about as many implied parents as there are commits in said branch.

2013-12-12cat-file: handle --batch format with missing type/sizeLibravatar Jeff King1-1/+10
Commit 98e2092 taught cat-file to stream blobs with --batch, which requires that we look up the object type before loading it into memory. As a result, we now print the object header from information in sha1_object_info, and the actual contents from the read_sha1_file. We double-check that the information we printed in the header matches the content we are about to show. Later, commit 93d2a60 allowed custom header lines for --batch, and commit 5b08640 made type lookups optional. As a result, specifying a header line without the type or size means that we will not look up those items at all. This causes our double-checking to erroneously die with an error; we think the type or size has changed, when in fact it was simply left at "0". For the size, we can fix this by only doing the consistency double-check when we have retrieved the size via sha1_object_info. In the case that we have not retrieved the value, that means we also did not print it, so there is nothing for us to check that we are consistent with. We could do the same for the type. However, besides our consistency check, we also care about the type in deciding whether to stream or not. So instead of handling the case where we do not know the type, this patch instead makes sure that we always trigger a type lookup when we are printing, so that even a format without the type will stream as we would in the normal case.

2013-12-12cat-file: pass expand_data to print_object_or_dieLibravatar Jeff King1-10/+11
We currently individually pass the sha1, type, and size fields calculated by sha1_object_info. However, if we pass the whole struct, the called function can make more intelligent decisions about which fields were actually filled by sha1_object_info. This patch takes that first refactoring step, passing the whole struct, so further patches can make those decisions with less noise in their diffs. There should be no functional change to this patch (aside from a minor typo fix in the error message). As a side effect, we can rename the local variables in the function to "type" and "size", since the names are no longer taken.

2013-12-09git fetch-pack: add --diag-urlLibravatar Torsten Bögershausen1-3/+11
The main purpose is to trace the URL parser called by git_connect() in connect.c The main features of the parser can be listed as this: - parse out host and path for URLs with a scheme (git:// file:// ssh://) - parse host names embedded by [] correctly - extract the port number, if present - separate URLs like "file" (which are local) from URLs like "host:repo" which should use ssh Add the new parameter "--diag-url" to "git fetch-pack", which prints the value for protocol, host and path to stderr and exits.

2013-12-09rev-parse: be more careful with munging argumentsLibravatar Jeff King1-1/+5
When rev-parse looks at whether an argument like "foo..bar" or "foobar^@" is a difference or parent-shorthand, it internally munges the arguments so that it can pass the individual rev arguments to get_sha1(). However, we do not consistently un-munge the result. For cases where we do not match (e.g., "doesnotexist..HEAD"), we would then want to try to treat the argument as a filename. try_difference gets() this right, and always unmunges in this case. However, try_parent_shorthand() never unmunges, leading to incorrect error messages, or even incorrect results: $ git rev-parse foobar^@ foobar fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar^@ foobar For cases where we do match, neither function unmunges. This does not currently matter, since we are done with the argument. However, a future patch will do further processing, and this prepares for it. In addition, it's simply a confusing interface for some cases to modify the const argument, and others not to.

2013-12-09rev-parse: correctly diagnose revision errors before "--"Libravatar Jeff King1-0/+10
Rev-parse understands that a "--" may separate revisions and filenames, and that anything after the "--" is taken as-is. However, it does not understand that anything before the token must be a revision (which is the usual rule implemented by the setup_revisions parser). Since rev-parse prefers revisions to files when parsing before the "--", we end up with the correct result (if such an argument is a revision, we parse it as one, and if it is not, it is an error either way). However, we misdiagnose the errors: $ git rev-parse foobar -- >/dev/null fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar -- >/dev/null fatal: bad flag '--' used after filename In both cases, we should know that the real error is that "foobar" is meant to be a revision, but could not be resolved.

2013-12-05commit -v: strip diffs and submodule shortlogs from the commit messageLibravatar Jens Lehmann1-6/+3
When using the '-v' option of "git commit" the diff added to the commit message temporarily for editing is stripped off after the user exited the editor by searching for "\ndiff --git " and truncating the commmit message there if it is found. But this approach has two problems: - when the commit message itself contains a line starting with "diff --git" it will be truncated there prematurely; and - when the "diff.submodule" setting is set to "log", the diff may start with "Submodule <hash1>..<hash2>", which will be left in the commit message while it shouldn't. Fix that by introducing a special scissor separator line starting with the comment character ('#' or the core.commentChar config if set) followed by two lines describing what it is for. The scissor line - which will not be translated - is used to reliably detect the start of the diff so it can be chopped off from the commit message, no matter what the user enters there. Turn a known test failure fixed by this change into a successful test; also add one for a diff starting with a submodule log and another one for proper handling of the comment char.

2013-10-30for-each-ref: avoid loading objects to print %(objectname)Libravatar Jeff King1-9/+20
If you ask for-each-ref to print each ref and its object, like: git for-each-ref --format='%(objectname) %(refname)' this should involve little more work than looking at the ref files (and packed-refs) themselves. However, for-each-ref will actually load each object from disk just to print its sha1. For most repositories, this isn't a big deal, but it can be noticeable if you have a large number of refs to print. Here are best-of-five timings for the command above on a repo with ~10K refs: [before] real 0m0.112s user 0m0.092s sys 0m0.016s [after] real 0m0.014s user 0m0.012s sys 0m0.000s This patch checks for %(objectname) and %(objectname:short) before we actually parse the object (and the rest of the code is smart enough to avoid parsing if we have filled all of our placeholders). Note that we can't simply move the objectname parsing code into the early loop. If the "deref" form %(*objectname) is used, then we do need to parse the object in order to peel the tag. So instead of moving the code, we factor it out into a separate function that can be called for both cases. While we're at it, we add some basic tests for the dereferenced placeholders, which were not tested at all before. This helps ensure we didn't regress that case.
