2018-11-18Merge branch 'jk/close-duped-fd-before-unlock-for-bundle'Libravatar Junio C Hamano1-21/+18
When "git bundle" aborts due to an empty commit ranges (i.e. resulting in an empty pack), it left a file descriptor to an lockfile open, which resulted in leftover lockfile on Windows where you cannot remove a file with an open file descriptor. This has been corrected. * jk/close-duped-fd-before-unlock-for-bundle: bundle: dup() output descriptor closer to point-of-use
2018-11-17bundle: dup() output descriptor closer to point-of-useLibravatar Jeff King1-21/+18
When writing a bundle to a file, the bundle code actually creates "your.bundle.lock" using our lockfile interface. We feed that output descriptor to a child git-pack-objects via run-command, which has the quirk that it closes the output descriptor in the parent. To avoid confusing the lockfile code (which still thinks the descriptor is valid), we dup() it, and operate on the duplicate. However, this has a confusing side effect: after the dup() but before we call pack-objects, we have _two_ descriptors open to the lockfile. If we call die() during that time, the lockfile code will try to clean up the partially-written file. It knows to close() the file before unlinking, since on some platforms (i.e., Windows) the open file would block the deletion. But it doesn't know about the duplicate descriptor. On Windows, triggering an error at the right part of the code will result in the cleanup failing and the lockfile being left in the filesystem. We can solve this by moving the dup() much closer to start_command(), shrinking the window in which we have the second descriptor open. It's easy to place this in such a way that no die() is possible. We could still die due to a signal in the exact wrong moment, but we already tolerate races there (e.g., a signal could come before we manage to put the file on the cleanup list in the first place). As a bonus, this shields create_bundle() itself from the duplicate-fd trick, and we can simplify its error handling (note that the lock rollback now happens unconditionally, but that's OK; it's a noop if we didn't open the lock in the first place). The included test uses an empty bundle to cause a failure at the right spot in the code, because that's easy to trigger (the other likely errors are write() problems like ENOSPC). Note that it would already pass on non-Windows systems (because they are happy to unlink an already-open file).

2018-08-29convert "oidcmp() != 0" to "!oideq()"Libravatar Jeff King1-1/+1
This is the flip side of the previous two patches: checking for a non-zero oidcmp() can be more strictly expressed as inequality. Like those patches, we write "!= 0" in the coccinelle transformation, which covers by isomorphism the more common: if (oidcmp(E1, E2)) As with the previous two patches, this patch can be achieved almost entirely by running "make coccicheck"; the only differences are manual line-wrap fixes to match the original code. There is one thing to note for anybody replicating this, though: coccinelle 1.0.4 seems to miss the case in builtin/tag.c, even though it's basically the same as all the others. Running with 1.0.7 does catch this, so presumably it's just a coccinelle bug that was fixed in the interim. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h.

2018-05-10lock_file: make function-local locks non-staticLibravatar Martin Ågren1-1/+1
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.

2017-12-28bundle: avoid using the rev_info flag leak_pendingLibravatar René Scharfe1-19/+16
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.

2017-09-24leak_pending: use `object_array_clear()`, not `free()`Libravatar Martin Ågren1-1/+8
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.

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.

2017-04-27timestamp_t: a new data type for timestampsLibravatar Johannes Schindelin1-1/+1
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

2015-08-10create_bundle(): duplicate file descriptor to avoid closing it twiceLibravatar Michael Haggerty1-10/+16
write_pack_data() passes bundle_fd to start_command() to be used as the stdout of pack-objects. But start_command() closes its stdout if it is > 1. This is a problem if bundle_fd is the fd of a lock_file, because commit_lock_file() will also try to close the fd. So the old code suppressed commit_lock_file()'s usual behavior of closing the file descriptor by setting the lock_file object's fd field to -1. But this is not really kosher. Code here shouldn't be mutating fields within the lock_file object. Instead, duplicate the file descriptor before passing it to write_pack_data(). Then that function can close its copy without closing the copy held in the lock_file object. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-10-01lockfile.h: extract new header file for the functions in lockfile.cLibravatar Michael Haggerty1-0/+1
Move the interface declaration for the functions in lockfile.c from cache.h to a new file, lockfile.h. Add #includes where necessary (and remove some redundant includes of cache.h by files that already include builtin.h). Move the documentation of the lock_file state diagram from lockfile.c to the new header file. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-08-20run-command: introduce CHILD_PROCESS_INITLibravatar René Scharfe1-4/+2
Most struct child_process variables are cleared using memset first after declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to initialize them statically instead. That's shorter, doesn't require a function call and is slightly more readable (especially given that we already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

2014-08-07bundle: fix exclusion of annotated tagsLibravatar Lukas Fleischer1-2/+2
In commit c9a42c4 (bundle: allow rev-list options to exclude annotated tags, 2009-01-02), support for excluding annotated tags outside the specified date range was added. However, the wrong order of parameters was chosen when calling memchr(). Fix this by swapping the character to search for with the maximum length parameter. Also cover this behavior with an additional test. Signed-off-by: Lukas Fleischer <git@cryptocrack.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-07-18bundle: use internal argv_array of struct child_process in create_bundle()Libravatar René Scharfe1-10/+5
Use the existing argv_array member instead of providing our own. This way the argv_array is cleared after use automatically for us; it was leaking before. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-03-25object.h: centralize object flag allocationLibravatar Nguyễn Thái Ngọc Duy1-0/+1
While the field "flags" is mainly used by the revision walker, it is also used in many other places. Centralize the whole flag allocation to one place for a better overview (and easier to move flags if we have too).

* sh/use-hashcpy: Use hashcpy() when copying object names
2014-03-06Use hashcpy() when copying object namesLibravatar Sun He1-1/+1
We invented hashcpy() to keep the abstraction of "object name" behind it. Use it instead of calling memcpy() with hard-coded 20-byte length when moving object names between pieces of memory. Leave ppc/sha1.c as-is, because the function is about the SHA-1 hash algorithm whose output is and will always be 20 bytes.
