2017-12-19builtin/describe.c: describe a blobStefan Beller
Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) When describing commits, we try to anchor them to tags or refs, as these are conceptually on a higher level than the commit. And if there is no ref or tag that matches exactly, we're out of luck. So we employ a heuristic to make up a name for the commit. These names are ambiguous, there might be different tags or refs to anchor to, and there might be different path in the DAG to travel to arrive at the commit precisely. When describing a blob, we want to describe the blob from a higher layer as well, which is a tuple of (commit, deep/path) as the tree objects involved are rather uninteresting. The same blob can be referenced by multiple commits, so how we decide which commit to use? This patch implements a rather naive approach on this: As there are no back pointers from blobs to commits in which the blob occurs, we'll start walking from any tips available, listing the blobs in-order of the commit and once we found the blob, we'll take the first commit that listed the blob. For example git describe --tags v0.99:Makefile conversion-901-g7672db20c2:Makefile tells us the Makefile as it was in v0.99 was introduced in commit 7672db20. The walking is performed in reverse order to show the introduction of a blob rather than its last occurrence. [1] Signed-off-by: Stefan Beller <> Signed-off-by: Junio C Hamano <>
2017-11-16builtin/describe.c: factor out describe_commitStefan Beller
Factor out describing commits into its own function `describe_commit`, which will put any output to stdout into a strbuf, to be printed afterwards. As the next patch will teach Git to describe blobs using a commit and path, this refactor will make it easy to reuse the code describing commits.

2017-10-11describe: do not use cmd_*() as a subroutineJunio C Hamano
The cmd_foo() function is a moral equivalent of 'main' for a Git subcommand 'git foo', and as such, it is allowed to do many things that make it unsuitable to be called as a subroutine, including - call exit(3) to terminate the process; - allocate resource held and used throughout its lifetime, without releasing it upon return/exit; - rely on global variables being initialized at program startup, and update them as needed, making another clean invocation of the function impossible. The call to cmd_diff_index() "git describe" makes has been working by accident that the function did not call exit(3); it sets a bad precedent for people to cut and paste. We could invoke it via the run_command() interface, but the diff family of commands have helper functions in diff-lib.c that are meant to be usable as subroutines, and using the latter does not make the resulting code all that longer. Use it. Note that there is also an invocation of cmd_name_rev() at the end; "git describe --contains" massages its command line arguments to be suitable for "git name-rev" invocation and jumps to it, never to regain control. This call is left as-is as an exception to the rule. When we start to allow calling name-rev repeatedly as a helper function, we would be able to remove this call as well.

2017-09-07hashmap: add API to disable item counting when threadedJeff Hostetler
This is to address concerns raised by ThreadSanitizer on the mailing list about threaded unprotected R/W access to map.size with my previous "disallow rehash" change (0607e10009ee4e37cb49b4cec8d28a9dda1656a4). See: Add API to hashmap to disable item counting and thus automatic rehashing. Also include API to later re-enable them. When item counting is disabled, the map.size field is invalid. So to prevent accidents, the field has been renamed and an accessor function hashmap_get_size() has been added. All direct references to this field have been been updated. And the name of the field changed to map.private_size to communicate this. Here is the relevant output from ThreadSanitizer showing the problem: WARNING: ThreadSanitizer: data race (pid=10554) Read of size 4 at 0x00000082d488 by thread T2 (mutexes: write M16): #0 hashmap_add hashmap.c:209 #1 hash_dir_entry_with_parent_and_prefix name-hash.c:302 #2 handle_range_dir name-hash.c:347 #3 handle_range_1 name-hash.c:415 #4 lazy_dir_thread_proc name-hash.c:471 #5 <null> <null> Previous write of size 4 at 0x00000082d488 by thread T1 (mutexes: write M31): #0 hashmap_add hashmap.c:209 #1 hash_dir_entry_with_parent_and_prefix name-hash.c:302 #2 handle_range_dir name-hash.c:347 #3 handle_range_1 name-hash.c:415 #4 handle_range_dir name-hash.c:380 #5 handle_range_1 name-hash.c:415 #6 lazy_dir_thread_proc name-hash.c:471 #7 <null> <null> Martin gives instructions for running TSan on test t3008 in this post: Signed-off-by: Jeff Hostetler <> Signed-off-by: Junio C Hamano <>

2017-06-30hashmap.h: compare function has access to a data fieldStefan Beller
When using the hashmap a common need is to have access to caller provided data in the compare function. A couple of times we abuse the keydata field to pass in the data needed. This happens for example in patch-ids.c. This patch changes the function signature of the compare function to have one more void pointer available. The pointer given for each invocation of the compare function must be defined in the init function of the hashmap and is just passed through. Documentation of this new feature is deferred to a later patch. This is a rather mechanical conversion, just adding the new pass-through parameter. However while at it improve the naming of the fields of all compare functions used by hashmaps by ensuring unused parameters are prefixed with 'unused_' and naming the parameters what they are (instead of 'unused' make it 'unused_keydata').

Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

To keep this property of only erroring out, when not in a repository, severe (submodule) errors must be downgraded to reporting them gently instead of having git-describe error out completely.

Teach git-describe the `--exclude` option which will allow specifying a glob pattern of tags to ignore. This can be combined with the `--match` patterns to enable more flexibility in determining which tags to consider. For example, suppose you wish to find the first official release tag that contains a certain commit. If we assume that official release tags are of the form "v*" and pre-release candidates include "*rc*" in their name, we can now find the first release tag that introduces the commit abcdef: git describe --contains --match="v*" --exclude="*rc*" abcdef Add documentation, tests, and completion for this change.

2015-08-25describe --contains: default to HEAD when no commit-ish is givenSZEDER Gábor
'git describe --contains' doesn't default to HEAD when no commit is given, and it doesn't produce any output, not even an error: ~/src/git ((v2.5.0))$ ./git describe --contains ~/src/git ((v2.5.0))$ ./git describe --contains HEAD v2.5.0^0 Unlike other 'git describe' options, the '--contains' code path is implemented by calling 'name-rev' with a bunch of options plus all the commit-ishes that were passed to 'git describe'. If no commit-ish was present, then 'name-rev' got invoked with none, which then leads to the behavior illustrated above. Porcelain commands usually default to HEAD when no commit-ish is given, and 'git describe' already does so in all other cases, so it should do so with '--contains' as well. Pass HEAD to 'name-rev' when no commit-ish is given on the command line to make '--contains' behave consistently with other 'git describe' options. While at it, use argv_array_pushv() instead of the loop to pass commit-ishes to 'git name-rev'. 'git describe's short help already indicates that the commit-ish is optional, but the synopsis in the man page doesn't, so update it accordingly as well.

To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions.

This flexibility is currently only needed by find_dir_entry() in name-hash.c (and compat/win32/fscache.c in the msysgit fork). All other (currently five) call sites of hashmap_get() have to set up a near emtpy entry structure, resulting in duplicate code like this: struct hashmap_entry keyentry; hashmap_entry_init(&keyentry, hash(key)); return hashmap_get(map, &keyentry, key); Add a hashmap_get_from_hash() API that allows hashmap lookups by just specifying the key and its hash code, i.e.: return hashmap_get_from_hash(map, hash(key), key); Signed-off-by: Karsten Blees <> Signed-off-by: Junio C Hamano <>

As the whole processing is internally delegated to name-rev, if we unwrap tags down to the underlying commit when invoking name-rev, it will make the name-rev issue an error message based on the unwrapped object name (i.e. either 40-hex object name, or "$tag^0") that is different from what the end-user gave to the command when the commit cannot be described. Introduce an internal option --peel-tag to the name-rev to tell it to unwrap a tag in its input from the command line. Signed-off-by: Junio C Hamano <>
