packfile: rename close_all_packs to close_object_store

2019-06-12T18:33:54Z

The close_all_packs() method is now responsible for more than just pack-files. It also closes the commit-graph and the multi-pack-index. Rename the function to be more descriptive of its larger role. The name also fits because the input parameter is a raw_object_store. Signed-off-by: Derrick Stolee Signed-off-by: Junio C Hamano

object: fix leak of shallow_stat

2019-02-07T21:02:28Z

In eee4502baaf ("shallow: migrate shallow information into the object parser", 2018-05-17), we added a stat_validity pointer into the parsed_object_pool struct, but did not add code to free this in parsed_object_pool_clear(). This leak was found by fuzz-commit-graph. Clear the struct and then free it in parsed_object_pool_clear() to prevent the leak. Signed-off-by: Josh Steadmon Signed-off-by: Junio C Hamano

Merge branch 'sg/object-as-type-commit-graph-fix'

2019-02-05T22:26:19Z

The commit-graph facility did not work when in-core objects that are promoted from unknown type to commit (e.g. a commit that is accessed via a tag that refers to it) were involved, which has been corrected. * sg/object-as-type-commit-graph-fix: object_as_type: initialize commit-graph-related fields of 'struct commit'

object_as_type: initialize commit-graph-related fields of 'struct commit'

2019-01-28T00:55:57Z

When the commit graph and generation numbers were introduced in commits 177722b344 (commit: integrate commit graph with commit parsing, 2018-04-10) and 83073cc994 (commit: add generation number to struct commit, 2018-04-25), they tried to make sure that the corresponding 'graph_pos' and 'generation' fields of 'struct commit' are initialized conservatively, as if the commit were not included in the commit-graph file. Alas, initializing those fields only in alloc_commit_node() missed the case when an object that happens to be a commit is first looked up via lookup_unknown_object(), and is then later converted to a 'struct commit' via the object_as_type() helper function (either calling it directly, or as part of a subsequent lookup_commit() call). Consequently, both of those fields incorrectly remain set to zero, which means e.g. that the commit is present in and is the first entry of the commit-graph file. This will result in wrong timestamp, parent and root tree hashes, if such a 'struct commit' instance is later filled from the commit-graph. Extract the initialization of 'struct commit's fields from alloc_commit_node() into a helper function, and call it from object_as_type() as well, to make sure that it properly initializes the two commit-graph-related fields, too. With this helper function it is hopefully less likely that any new fields added to 'struct commit' in the future would remain uninitialized. With this change alloc_commit_index() won't have any remaining callers outside of 'alloc.c', so mark it as static. Signed-off-by: SZEDER Gábor Signed-off-by: Junio C Hamano

prefer "hash mismatch" to "sha1 mismatch"

2019-01-08T17:41:06Z

To future-proof ourselves against a change in the hash, let's use the more generic "hash mismatch" to refer to integrity problems. Note that we do advertise this exact string in git-fsck(1). However, the message itself is marked for translation, meaning we do not expect it to be machine-readable. While we're touching that documentation, let's also update it for grammar and clarity.

object-store: factor out odb_clear_loose_cache()

2019-01-08T17:40:19Z

Add and use a function for emptying the loose object cache, so callers don't have to know any of its implementation details. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

commit: prepare free_commit_buffer and release_commit_memory for any repo

2018-12-28T18:06:33Z

Pass the object pool to free_commit_buffer and release_commit_memory, such that we can eliminate access to 'the_repository'. Also remove the TODO in release_commit_memory, as commit->util was removed in 9d2c97016f (commit.h: delete 'util' field in struct commit, 2018-05-19) Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

object: parse_object to honor its repository argument

2018-11-14T08:22:40Z
