Merge branch 'ma/lockfile-cleanup'

2018-05-30T05:04:05Z

Code clean-up to adjust to a more recent lockfile API convention that allows lockfile instances kept on the stack. * ma/lockfile-cleanup: lock_file: move static locks into functions lock_file: make function-local locks non-static refs.c: do not die if locking fails in `delete_pseudoref()` refs.c: do not die if locking fails in `write_pseudoref()` t/helper/test-write-cache: clean up lock-handling

lock_file: make function-local locks non-static

2018-05-10T05:54:45Z

Placing `struct lock_file`s on the stack used to be a bad idea, because the temp- and lockfile-machinery would keep a pointer into the struct. But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap, 2017-09-05), we can safely have lockfiles on the stack. (This applies even if a user returns early, leaving a locked lock behind.) These `struct lock_file`s are local to their respective functions and we can drop their staticness. For good measure, I have inspected these sites and come to believe that they always release the lock, with the possible exception of bailing out using `die()` or `exit()` or by returning from a `cmd_foo()`. As pointed out by Jeff King, it would be bad if someone held on to a `struct lock_file *` for some reason. After some grepping, I agree with his findings: no-one appears to be doing that.

sha1_file: convert read_sha1_file to struct object_id

2018-03-14T16:23:50Z

Convert read_sha1_file to take a pointer to struct object_id and rename it read_object_file. Do the same for read_sha1_file_extended. Convert one use in grep.c to use the new function without any other code change, since the pointer being passed is a void pointer that is already initialized with a pointer to struct object_id. Update the declaration and definitions of the modified functions, and apply the following semantic patch to convert the remaining callers: @@ expression E1, E2, E3; @@ - read_sha1_file(E1.hash, E2, E3) + read_object_file(&E1, E2, E3) @@ expression E1, E2, E3; @@ - read_sha1_file(E1->hash, E2, E3) + read_object_file(E1, E2, E3) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1.hash, E2, E3, E4) + read_object_file_extended(&E1, E2, E3, E4) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1->hash, E2, E3, E4) + read_object_file_extended(E1, E2, E3, E4) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

Merge branch 'rs/lose-leak-pending'

API clean-up around revision traversal. * rs/lose-leak-pending: commit: remove unused function clear_commit_marks_for_object_array() revision: remove the unused flag leak_pending checkout: avoid using the rev_info flag leak_pending bundle: avoid using the rev_info flag leak_pending bisect: avoid using the rev_info flag leak_pending object: add clear_commit_marks_all() ref-filter: use clear_commit_marks_many() in do_merge_filter() commit: use clear_commit_marks_many() in remove_redundant() commit: avoid allocation in clear_commit_marks_many()

bundle: avoid using the rev_info flag leak_pending

2017-12-28T21:50:05Z

The leak_pending flag is so awkward to use that multiple comments had to be added around each occurrence. We use it for remembering the prerequisites for the bundle. That is easy, though: We have the ref_list named "prerequisites" in the header for just that purpose. Use this original list of prerequisites to check if all of them are present and to clear their commit marks afterward. The two new loops are intentionally kept similar to the first one in the function. Calling parse_object() a second time is expected be quick and successful in each case -- any errors should have been handled in the first round.

refs: convert dwim_ref and expand_ref to struct object_id

2017-10-16T02:05:51Z

All of the callers of these functions just pass the hash member of a struct object_id, so convert them to use a pointer to struct object_id directly. Insert a check for NULL in expand_ref on a temporary basis; this check can be removed when resolve_ref_unsafe is converted as well. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

refs: convert read_ref and read_ref_full to object_id

2017-10-16T02:05:50Z

All but two of the call sites already have parameters using the hash parameter of struct object_id, so convert them to take a pointer to the struct directly. Also convert refs_read_refs_full, the underlying implementation. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

leak_pending: use `object_array_clear()`, not `free()`

2017-09-24T01:05:57Z

Setting `leak_pending = 1` tells `prepare_revision_walk()` not to release the `pending` array, and makes that the caller's responsibility. See 4a43d374f (revision: add leak_pending flag, 2011-10-01) and 353f5657a (bisect: use leak_pending flag, 2011-10-01). Commit 1da1e07c8 (clean up name allocation in prepare_revision_walk, 2014-10-15) fixed a memory leak in `prepare_revision_walk()` by switching from `free()` to `object_array_clear()`. However, where we use the `leak_pending`-mechanism, we're still only calling `free()`. Use `object_array_clear()` instead. Copy some helpful comments from 353f5657a to the other callers that we update to clarify the memory responsibilities, and to highlight that the commits are not affected when we clear the array -- it is indeed correct to both tidy up the commit flags and clear the object array. Document `leak_pending` in revision.h to help future users get this right. Signed-off-by: Martin Ågren Reviewed-by: Jeff King Signed-off-by: Junio C Hamano
