When "update-index --unresolve $path" cannot find the resolve-undo record for the path the user requested to unresolve, it stuffs the blobs from HEAD and MERGE_HEAD to stage #2 and stage #3 as a fallback. For this reason, the operation does not even start unless both "HEAD" and "MERGE_HEAD" exist. This is suboptimal in a few ways: * It does not recreate stage #1. Even though it is a correct design decision not to do so (because it is impossible to recreate in general cases, without knowing how we got there, including what merge strategy was used), it is much less useful not to have that information in the index. * It limits the "unresolve" operation only during a conflicted "git merge" and nothing else. Other operations like "rebase", "cherry-pick", and "switch -m" may result in conflicts, and the user may want to unresolve the conflict that they incorrectly resolved in order to redo the resolution, but the fallback would not kick in. * Most importantly, the entire "unresolve" operation is disabled after a conflicted merge is committed and MERGE_HEAD is removed, even though the index has perfectly usable resolve-undo records. By lazily reading the HEAD and MERGE_HEAD only when we need to go to the fallback codepath, we will allow cases where resolve-undo records are available (which is 100% of the time, unless the user is reading from an index file created by Git more than 10 years ago) to proceed even after a conflicted merge was committed, during other mergy operations that do not use MERGE_HEAD, or after the result of such mergy operations has been committed.

When t5583-push-branches.sh was originally introduced via 425b4d7 (push: introduce '--branches' option, 2023-05-06), it was not leak-free. In fact, the test did not even run correctly until 022fbb6 (t5583: fix shebang line, 2023-05-12), but after applying that patch, we see a failure at t5583.8: ==2529087==ERROR: LeakSanitizer: detected memory leaks Direct leak of 384 byte(s) in 1 object(s) allocated from: #0 0x7fb536330986 in __interceptor_realloc ../../../../src/libsanitizer/lsan/lsan_interceptors.cpp:98 #1 0x55e07606cbf9 in xrealloc wrapper.c:140 #2 0x55e075fb6cb3 in prio_queue_put prio-queue.c:42 #3 0x55e075ec81cb in get_reachable_subset commit-reach.c:917 #4 0x55e075fe9cce in add_missing_tags remote.c:1518 #5 0x55e075fea1e4 in match_push_refs remote.c:1665 git#6 0x55e076050a8e in transport_push transport.c:1378 #7 0x55e075e2eb74 in push_with_options builtin/push.c:401 git#8 0x55e075e2edb0 in do_push builtin/push.c:458 git#9 0x55e075e2ff7a in cmd_push builtin/push.c:702 git#10 0x55e075d8aaf0 in run_builtin git.c:452 git#11 0x55e075d8af08 in handle_builtin git.c:706 git#12 0x55e075d8b12c in run_argv git.c:770 git#13 0x55e075d8b6a0 in cmd_main git.c:905 git#14 0x55e075e81f07 in main common-main.c:60 git#15 0x7fb5360ab6c9 in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 git#16 0x7fb5360ab784 in __libc_start_main_impl ../csu/libc-start.c:360 git#17 0x55e075d88f40 in _start (git+0x1ff40) (BuildId: 38ad998b85a535e786129979443630d025ec2453) SUMMARY: LeakSanitizer: 384 byte(s) leaked in 1 allocation(s). This leak was addressed independently via 68b5117 (commit-reach: fix memory leak in get_reachable_subset(), 2023-06-03), which makes t5583 leak-free. But t5583 was not in the tree when 68b5117 was written, and the two only met after the latter was merged back in via 693bde4 (Merge branch 'mh/commit-reach-get-reachable-plug-leak', 2023-06-20). At that point, t5583 was leak-free. Let's mark it as such accordingly.

It is tempting to think of "files and directories" of the current directory as valid inputs to the add and set subcommands of git sparse-checkout. However, in non-cone mode, they often aren't and using them as potential completions leads to *many* forms of confusion: Issue #1. It provides the *wrong* files and directories. For git sparse-checkout add we always want to add files and directories not currently in our sparse checkout, which means we want file and directories not currently present in the current working tree. Providing the files and directories currently present is thus always wrong. For git sparse-checkout set we have a similar problem except in the subset of cases where we are trying to narrow our checkout to a strict subset of what we already have. That is not a very common scenario, especially since it often does not even happen to be true for the first use of the command; for years we required users to create a sparse-checkout via git sparse-checkout init git sparse-checkout set <args...> (or use a clone option that did the init step for you at clone time). The init command creates a minimal sparse-checkout with just the top-level directory present, meaning the set command has to be used to expand the checkout. Thus, only in a special and perhaps unusual cases would any of the suggestions from normal file and directory completion be appropriate. Issue #2: Suggesting patterns that lead to warnings is unfriendly. If the user specifies any regular file and omits the leading '/', then the sparse-checkout command will warn the user that their command is problematic and suggest they use a leading slash instead. Issue #3: Completion gets confused by leading '/', and provides wrong paths. Users often want to anchor their patterns to the toplevel of the repository, especially when listing individual files. There are a number of reasons for this, but notably even sparse-checkout encourages them to do so (as noted above). However, if users do so (via adding a leading '/' to their pattern), then bash completion will interpret the leading slash not as a request for a path at the toplevel of the repository, but as a request for a path at the root of the filesytem. That means at best that completion cannot help with such paths, and if it does find any completions, they are almost guaranteed to be wrong. Issue #4: Suggesting invalid patterns from subdirectories is unfriendly. There is no per-directory equivalent to .gitignore with sparse-checkouts. There is only a single worktree-global $GIT_DIR/info/sparse-checkout file. As such, paths to files must be specified relative to the toplevel of a repository. Providing suggestions of paths that are relative to the current working directory, as bash completion defaults to, is wrong when the current working directory is not the worktree toplevel directory. Issue #5: Paths with special characters will be interpreted incorrectly The entries in the sparse-checkout file are patterns, not paths. While most paths also qualify as patterns (though even in such cases it would be better for users to not use them directly but prefix them with a leading '/'), there are a variety of special characters that would need special escaping beyond the normal shell escaping: '*', '?', '\', '[', ']', and any leading '#' or '!'. If completion suggests any such paths, users will likely expect them to be treated as an exact path rather than as a pattern that might match some number of files other than 1. However, despite the first four issues, we can note that _if_ users are using tab completion, then they are probably trying to specify a path in the index. As such, we transform their argument into a top-level-rooted pattern that matches such a file. For example, if they type: git sparse-checkout add Make<TAB> we could "complete" to git sparse-checkout add /Makefile or, if they ran from the Documentation/technical/ subdirectory: git sparse-checkout add m<TAB> we could "complete" it to: git sparse-checkout add /Documentation/technical/multi-pack-index.txt Note in both cases I use "complete" in quotes, because we actually add characters both before and after the argument in question, so we are kind of abusing "bash completions" to be "bash completions AND beginnings". The fifth issue is a bit stickier, especially when you consider that we not only need to deal with escaping issues because of special meanings of patterns in sparse-checkout & gitignore files, but also that we need to consider escaping issues due to ls-files needing to sometimes quote or escape characters, and because the shell needs to escape some characters. The multiple interacting forms of escaping could get ugly; this patch makes no attempt to do so and simply documents that we decided to not deal with those corner cases for now but at least get the common cases right.

The t5309 script triggers a racy false positive with SANITIZE=leak on a multi-core system.

Aborted What happens is this: 0. We construct a bogus pack with a duplicate object in it and trigger index-pack. 1. We spawn a bunch of worker threads to resolve deltas (on my system it is 16 threads). 2. One of the threads sees the duplicate object and bails by calling exit(), taking down all of the threads. This is expected and is the point of the test. 3. At the time exit() is called, we may still be spawning threads from the main process via pthread_create(). LSan hooks thread creation to update its book-keeping; it has to know where each thread's stack is (so it can find entry points for reachable memory). So it calls pthread_getattr_np() to get information about the new thread. That may allocate memory that must be freed with a matching call to pthread_attr_destroy(). Probably LSan does that immediately, but if you're unlucky enough, the exit() will happen while it's between those two calls, and the allocated pthread_attr_t appears as a leak. This isn't a real leak. It's not even in our code, but rather in the LSan instrumentation code. So we could just ignore it. But the false positive can cause people to waste time tracking it down. It's possibly something that LSan could protect against (e.g., cover the getattr/destroy pair with a mutex, and then in the final post-exit() check for leaks try to take the same mutex). But I don't know enough about LSan to say if that's a reasonable approach or not (or if my analysis is even completely correct). In the meantime, it's pretty easy to avoid the race by making creation of the worker threads "atomic". That is, we'll spawn all of them before letting any of them start to work. That's easy to do because we already have a work_lock() mutex for handing out that work. If the main process takes it, then all of the threads will immediately block until we've finished spawning and released it. This shouldn't make any practical difference for non-LSan runs. The thread spawning is quick, and could happen before any worker thread gets scheduled anyway. Probably other spots that use threads are subject to the same issues. But since we have to manually insert locking (and since this really is kind of a hack), let's not bother with them unless somebody experiences a similar racy false-positive in practice.

When performing multi-pack reuse, reuse_partial_packfile_from_bitmap() is responsible for generating an array of bitmapped_pack structs from which to perform reuse. In the multi-pack case, we loop over the MIDXs packs and copy the result of calling `nth_bitmapped_pack()` to construct the list of reusable paths. But we may also want to do pack-reuse over a single pack, either because we only had one pack to perform reuse over (in the case of single-pack bitmaps), or because we explicitly asked to do single pack reuse even with a MIDX[^1]. When this is the case, the array we generate of reusable packs contains only a single element, which is either (a) the pack attached to the single-pack bitmap, or (b) the MIDX's preferred pack. In 795006f (pack-bitmap: gracefully handle missing BTMP chunks, 2024-04-15), we refactored the reuse_partial_packfile_from_bitmap() function and stopped assigning the pack_int_id field when reusing only the MIDX's preferred pack. This results in an uninitialized read down in try_partial_reuse() like so: ==7474==WARNING: MemorySanitizer: use-of-uninitialized-value #0 0x55c5cd191dde in try_partial_reuse pack-bitmap.c:1887:8 #1 0x55c5cd191dde in reuse_partial_packfile_from_bitmap_1 pack-bitmap.c:2001:8 #2 0x55c5cd191dde in reuse_partial_packfile_from_bitmap pack-bitmap.c:2105:3 #3 0x55c5cce0bd0e in get_object_list_from_bitmap builtin/pack-objects.c:4043:3 #4 0x55c5cce0bd0e in get_object_list builtin/pack-objects.c:4156:27 #5 0x55c5cce0bd0e in cmd_pack_objects builtin/pack-objects.c:4596:3 git#6 0x55c5ccc8fac8 in run_builtin git.c:474:11 which happens when try_partial_reuse() tries to call midx_pair_to_pack_pos() when it tries to reject cross-pack deltas. Avoid the uninitialized read by ensuring that the pack_int_id field is set in the single-pack reuse case by setting it to either the MIDX preferred pack's pack_int_id, or '-1', in the case of single-pack bitmaps. In the latter case, we never read the pack_int_id field, so the choice of '-1' is intentional as a "garbage in, garbage out" measure. Guard against further regressions in this area by adding a test which ensures that we do not throw out deltas from the preferred pack as "cross-pack" due to an uninitialized pack_int_id. [^1]: This can happen for a couple of reasons, either because the repository is configured with 'pack.allowPackReuse=(true|single)', or because the MIDX was generated prior to the introduction of the BTMP chunk, which contains information necessary to perform multi-pack reuse.

Memory sanitizer (msan) is detecting a use of an uninitialized variable (`size`) in `read_attr_from_index`: ==2268==WARNING: MemorySanitizer: use-of-uninitialized-value #0 0x5651f3416504 in read_attr_from_index git/attr.c:868:11 #1 0x5651f3415530 in read_attr git/attr.c #2 0x5651f3413d74 in bootstrap_attr_stack git/attr.c:968:6 #3 0x5651f3413d74 in prepare_attr_stack git/attr.c:1004:2 #4 0x5651f3413d74 in collect_some_attrs git/attr.c:1199:2 #5 0x5651f3413144 in git_check_attr git/attr.c:1345:2 git#6 0x5651f34728da in convert_attrs git/convert.c:1320:2 #7 0x5651f3473425 in would_convert_to_git_filter_fd git/convert.c:1373:2 git#8 0x5651f357a35e in index_fd git/object-file.c:2630:34 git#9 0x5651f357aa15 in index_path git/object-file.c:2657:7 git#10 0x5651f35db9d9 in add_to_index git/read-cache.c:766:7 git#11 0x5651f35dc170 in add_file_to_index git/read-cache.c:799:9 git#12 0x5651f321f9b2 in add_files git/builtin/add.c:346:7 git#13 0x5651f321f9b2 in cmd_add git/builtin/add.c:565:18 git#14 0x5651f321d327 in run_builtin git/git.c:474:11 git#15 0x5651f321bc9e in handle_builtin git/git.c:729:3 git#16 0x5651f321a792 in run_argv git/git.c:793:4 git#17 0x5651f321a792 in cmd_main git/git.c:928:19 git#18 0x5651f33dde1f in main git/common-main.c:62:11 The issue exists because `size` is an output parameter from `read_blob_data_from_index`, but it's only modified if `read_blob_data_from_index` returns non-NULL. The read of `size` when calling `read_attr_from_buf` unconditionally may read from an uninitialized value. `read_attr_from_buf` checks that `buf` is non-NULL before reading from `size`, but by then it's already too late: the uninitialized read will have happened already. Furthermore, there's no guarantee that the compiler won't reorder things so that it checks `size` before checking `!buf`. Make the call to `read_attr_from_buf` conditional on `buf` being non-NULL, ensuring that `size` is not read if it's never set.

It was recently reported that concurrent reads and writes may cause the reftable backend to segfault. The root cause of this is that we do not properly keep track of reftable readers across reloads. Suppose that you have a reftable iterator and then decide to reload the stack while iterating through the iterator. When the stack has been rewritten since we have created the iterator, then we would end up discarding a subset of readers that may still be in use by the iterator. The consequence is that we now try to reference deallocated memory, which of course segfaults. One way to trigger this is in t5616, where some background maintenance jobs have been leaking from one test into another. This leads to stack traces like the following one: + git -c protocol.version=0 -C pc1 fetch --filter=blob:limit=29999 --refetch origin AddressSanitizer:DEADLYSIGNAL ================================================================= ==657994==ERROR: AddressSanitizer: SEGV on unknown address 0x7fa0f0ec6089 (pc 0x55f23e52ddf9 bp 0x7ffe7bfa1700 sp 0x7ffe7bfa1700 T0) ==657994==The signal is caused by a READ memory access. #0 0x55f23e52ddf9 in get_var_int reftable/record.c:29 #1 0x55f23e53295e in reftable_decode_keylen reftable/record.c:170 #2 0x55f23e532cc0 in reftable_decode_key reftable/record.c:194 #3 0x55f23e54e72e in block_iter_next reftable/block.c:398 #4 0x55f23e5573dc in table_iter_next_in_block reftable/reader.c:240 #5 0x55f23e5573dc in table_iter_next reftable/reader.c:355 git#6 0x55f23e5573dc in table_iter_next reftable/reader.c:339 #7 0x55f23e551283 in merged_iter_advance_subiter reftable/merged.c:69 git#8 0x55f23e55169e in merged_iter_next_entry reftable/merged.c:123 git#9 0x55f23e55169e in merged_iter_next_void reftable/merged.c:172 git#10 0x55f23e537625 in reftable_iterator_next_ref reftable/generic.c:175 git#11 0x55f23e2cf9c6 in reftable_ref_iterator_advance refs/reftable-backend.c:464 git#12 0x55f23e2d996e in ref_iterator_advance refs/iterator.c:13 git#13 0x55f23e2d996e in do_for_each_ref_iterator refs/iterator.c:452 git#14 0x55f23dca6767 in get_ref_map builtin/fetch.c:623 git#15 0x55f23dca6767 in do_fetch builtin/fetch.c:1659 git#16 0x55f23dca6767 in fetch_one builtin/fetch.c:2133 git#17 0x55f23dca6767 in cmd_fetch builtin/fetch.c:2432 git#18 0x55f23dba7764 in run_builtin git.c:484 git#19 0x55f23dba7764 in handle_builtin git.c:741 git#20 0x55f23dbab61e in run_argv git.c:805 git#21 0x55f23dbab61e in cmd_main git.c:1000 git#22 0x55f23dba4781 in main common-main.c:64 git#23 0x7fa0f063fc89 in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 git#24 0x7fa0f063fd44 in __libc_start_main_impl ../csu/libc-start.c:360 git#25 0x55f23dba6ad0 in _start (git+0xadfad0) (BuildId: 803b2b7f59beb03d7849fb8294a8e2145dd4aa27) While it is somewhat awkward that the maintenance processes survive tests in the first place, it is totally expected that reftables should work alright with concurrent writers. Seemingly they don't. The only underlying resource that we need to care about in this context is the reftable reader, which is responsible for reading a single table from disk. These readers get discarded immediately (unless reused) when calling `reftable_stack_reload()`, which is wrong. We can only close them once we know that there are no iterators using them anymore. Prepare for a fix by converting the reftable readers to be refcounted.

This one is a little bit more curious. In t6112, we have a test that exercises the `git rev-list --filter` option with invalid filters. We execute git-rev-list(1) via `test_must_fail`, which means that we check for leaks even though Git exits with an error code. This causes the following leak: Direct leak of 27 byte(s) in 1 object(s) allocated from: #0 0x5555555e6946 in realloc.part.0 lsan_interceptors.cpp.o #1 0x5555558fb4b6 in xrealloc wrapper.c:137:8 #2 0x5555558b6e06 in strbuf_grow strbuf.c:112:2 #3 0x5555558b7550 in strbuf_add strbuf.c:311:2 #4 0x5555557c1a88 in strbuf_addstr strbuf.h:310:2 #5 0x5555557c1d4c in parse_list_objects_filter list-objects-filter-options.c:261:3 git#6 0x555555885ead in handle_revision_pseudo_opt revision.c:2899:3 #7 0x555555884e20 in setup_revisions revision.c:3014:11 git#8 0x5555556c4b42 in cmd_rev_list builtin/rev-list.c:588:9 git#9 0x5555555ec5e3 in run_builtin git.c:483:11 git#10 0x5555555eb1e4 in handle_builtin git.c:749:13 git#11 0x5555555ec001 in run_argv git.c:819:4 git#12 0x5555555eaf94 in cmd_main git.c:954:19 git#13 0x5555556fd569 in main common-main.c:64:11 git#14 0x7ffff7ca714d in __libc_start_call_main (.../lib/libc.so.6+0x2a14d) git#15 0x7ffff7ca7208 in __libc_start_main@GLIBC_2.2.5 (.../libc.so.6+0x2a208) git#16 0x5555555ad064 in _start (git+0x59064) This leak is valid, as we call `die()` and do not clean up the memory at all. But what's curious is that this is the only leak reported, because we don't clean up any other allocated memory, either, and I have no idea why the leak sanitizer treats this buffer specially. In any case, we can work around the leak by shuffling things around a bit. Instead of calling `gently_parse_list_objects_filter()` and dying after we have modified the filter spec, we simply do so beforehand. Like this we don't allocate the buffer in the error case, which makes the reported leak go away. It's not pretty, but it manages to make t6112 leak free.

When running t5601 with the leak checker enabled we can see a hang in our CI systems. This hang seems to be system-specific, as I cannot reproduce it on my own machine. As it turns out, the issue is in those testcases that exercise cloning of `~repo`-style paths. All of the testcases that hang eventually end up interpreting "repo" as the username and will call getpwnam(3p) with that username. That should of course be fine, and getpwnam(3p) should just return an error. But instead, the leak sanitizer seems to be recursing while handling a call to `free()` in the NSS modules: #0 0x00007ffff7fd98d5 in _dl_update_slotinfo (req_modid=1, new_gen=2) at ../elf/dl-tls.c:720 #1 0x00007ffff7fd9ac4 in update_get_addr (ti=0x7ffff7a91d80, gen=<optimized out>) at ../elf/dl-tls.c:916 #2 0x00007ffff7fdc85c in __tls_get_addr () at ../sysdeps/x86_64/tls_get_addr.S:55 #3 0x00007ffff7a27e04 in __lsan::GetAllocatorCache () at ../../../../src/libsanitizer/lsan/lsan_linux.cpp:27 #4 0x00007ffff7a2b33a in __lsan::Deallocate (p=0x0) at ../../../../src/libsanitizer/lsan/lsan_allocator.cpp:127 #5 __lsan::lsan_free (p=0x0) at ../../../../src/libsanitizer/lsan/lsan_allocator.cpp:220 ... #261505 0x00007ffff7fd99f2 in free (ptr=<optimized out>) at ../include/rtld-malloc.h:50 #261506 _dl_update_slotinfo (req_modid=1, new_gen=2) at ../elf/dl-tls.c:822 #261507 0x00007ffff7fd9ac4 in update_get_addr (ti=0x7ffff7a91d80, gen=<optimized out>) at ../elf/dl-tls.c:916 #261508 0x00007ffff7fdc85c in __tls_get_addr () at ../sysdeps/x86_64/tls_get_addr.S:55 #261509 0x00007ffff7a27e04 in __lsan::GetAllocatorCache () at ../../../../src/libsanitizer/lsan/lsan_linux.cpp:27 #261510 0x00007ffff7a2b33a in __lsan::Deallocate (p=0x5020000001e0) at ../../../../src/libsanitizer/lsan/lsan_allocator.cpp:127 #261511 __lsan::lsan_free (p=0x5020000001e0) at ../../../../src/libsanitizer/lsan/lsan_allocator.cpp:220 #261512 0x00007ffff793da25 in module_load (module=0x515000000280) at ./nss/nss_module.c:188 #261513 0x00007ffff793dee5 in __nss_module_load (module=0x515000000280) at ./nss/nss_module.c:302 #261514 __nss_module_get_function (module=0x515000000280, name=name@entry=0x7ffff79b9128 "getpwnam_r") at ./nss/nss_module.c:328 #261515 0x00007ffff793e741 in __GI___nss_lookup_function (fct_name=<optimized out>, ni=<optimized out>) at ./nss/nsswitch.c:137 #261516 __GI___nss_next2 (ni=ni@entry=0x7fffffffa458, fct_name=fct_name@entry=0x7ffff79b9128 "getpwnam_r", fct2_name=fct2_name@entry=0x0, fctp=fctp@entry=0x7fffffffa460, status=status@entry=0, all_values=all_values@entry=0) at ./nss/nsswitch.c:120 #261517 0x00007ffff794c6a7 in __getpwnam_r (name=name@entry=0x501000000060 "repo", resbuf=resbuf@entry=0x7ffff79fb320 <resbuf>, buffer=<optimized out>, buflen=buflen@entry=1024, result=result@entry=0x7fffffffa4b0) at ../nss/getXXbyYY_r.c:343 #261518 0x00007ffff794c4d8 in getpwnam (name=0x501000000060 "repo") at ../nss/getXXbyYY.c:140 #261519 0x00005555557e37ff in getpw_str (username=0x5020000001a1 "repo", len=4) at path.c:613 #261520 0x00005555557e3937 in interpolate_path (path=0x5020000001a0 "~repo", real_home=0) at path.c:654 #261521 0x00005555557e3aea in enter_repo (path=0x501000000040 "~repo", strict=0) at path.c:718 #261522 0x000055555568f0ba in cmd_upload_pack (argc=1, argv=0x502000000100, prefix=0x0, repo=0x0) at builtin/upload-pack.c:57 #261523 0x0000555555575ba8 in run_builtin (p=0x555555a20c98 <commands+3192>, argc=2, argv=0x502000000100, repo=0x555555a53b20 <the_repo>) at git.c:481 #261524 0x0000555555576067 in handle_builtin (args=0x7fffffffaab0) at git.c:742 #261525 0x000055555557678d in cmd_main (argc=2, argv=0x7fffffffac58) at git.c:912 #261526 0x00005555556963cd in main (argc=2, argv=0x7fffffffac58) at common-main.c:64 Note that this stack is more than 260000 function calls deep.

I assume that this is a bug either in the leak sanitizer or in glibc, as I cannot reproduce it on my machine. In any case, let's work around the bug for now by marking those tests with the "!SANITIZE_LEAK" prereq.

There's a race with LSan when spawning threads and one of the threads calls die(). We worked around one such problem with index-pack in the previous commit, but it exists in git-grep, too.

But there's one twist in this case: the thread which calls die() is not one of the worker threads, but the main thread itself! So we need the main thread to wait in the barrier, too, until all threads have gotten to it. And thus we initialize the barrier for num_threads+1, to account for all of the worker threads plus the main one. If we then test as above, t0003 should run indefinitely.

In 1b9e9be (csum-file.c: use unsafe SHA-1 implementation when available, 2024-09-26) we have converted our `struct hashfile` to use the unsafe SHA1 backend, which results in a significant speedup. One needs to be careful with how to use that structure now though because callers need to consistently use either the safe or unsafe variants of SHA1, as otherwise one can easily trigger corruption. As it turns out, we have one inconsistent usage in our tree because we directly initialize `struct hashfile_checkpoint::ctx` with the safe variant of SHA1, but end up writing to that context with the unsafe ones. This went unnoticed so far because our CI systems do not exercise different hash functions for these two backends, and consequently safe and unsafe variants are equivalent. But when using SHA1DC as safe and OpenSSL as unsafe backend this leads to a crash an t1050: ++ git -c core.compression=0 add large1 AddressSanitizer:DEADLYSIGNAL ================================================================= ==1367==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000040 (pc 0x7ffff7a01a99 bp 0x507000000db0 sp 0x7fffffff5690 T0) ==1367==The signal is caused by a READ memory access. ==1367==Hint: address points to the zero page. #0 0x7ffff7a01a99 in EVP_MD_CTX_copy_ex (/nix/store/h1ydpxkw9qhjdxjpic1pdc2nirggyy6f-openssl-3.3.2/lib/libcrypto.so.3+0x201a99) (BuildId: 41746a580d39075fc85e8c8065b6c07fb34e97d4) #1 0x555555ddde56 in openssl_SHA1_Clone ../sha1/openssl.h:40:2 #2 0x555555dce2fc in git_hash_sha1_clone_unsafe ../object-file.c:123:2 #3 0x555555c2d5f8 in hashfile_checkpoint ../csum-file.c:211:2 #4 0x555555b9905d in deflate_blob_to_pack ../bulk-checkin.c:286:4 #5 0x555555b98ae9 in index_blob_bulk_checkin ../bulk-checkin.c:362:15 git#6 0x555555ddab62 in index_blob_stream ../object-file.c:2756:9 #7 0x555555dda420 in index_fd ../object-file.c:2778:9 git#8 0x555555ddad76 in index_path ../object-file.c:2796:7 git#9 0x555555e947f3 in add_to_index ../read-cache.c:771:7 git#10 0x555555e954a4 in add_file_to_index ../read-cache.c:804:9 git#11 0x5555558b5c39 in add_files ../builtin/add.c:355:7 git#12 0x5555558b412e in cmd_add ../builtin/add.c:578:18 git#13 0x555555b1f493 in run_builtin ../git.c:480:11 git#14 0x555555b1bfef in handle_builtin ../git.c:740:9 git#15 0x555555b1e6f4 in run_argv ../git.c:807:4 git#16 0x555555b1b87a in cmd_main ../git.c:947:19 git#17 0x5555561649e6 in main ../common-main.c:64:11 git#18 0x7ffff742a1fb in __libc_start_call_main (/nix/store/65h17wjrrlsj2rj540igylrx7fqcd6vq-glibc-2.40-36/lib/libc.so.6+0x2a1fb) (BuildId: bf320110569c8ec2425e9a0c5e4eb7e97f1fb6e4) git#19 0x7ffff742a2b8 in __libc_start_main@GLIBC_2.2.5 (/nix/store/65h17wjrrlsj2rj540igylrx7fqcd6vq-glibc-2.40-36/lib/libc.so.6+0x2a2b8) (BuildId: bf320110569c8ec2425e9a0c5e4eb7e97f1fb6e4) git#20 0x555555772c84 in _start (git+0x21ec84) ==1367==Register values: rax = 0x0000511000001080 rbx = 0x0000000000000000 rcx = 0x000000000000000c rdx = 0x0000000000000000 rdi = 0x0000000000000000 rsi = 0x0000507000000db0 rbp = 0x0000507000000db0 rsp = 0x00007fffffff5690 r8 = 0x0000000000000000 r9 = 0x0000000000000000 r10 = 0x0000000000000000 r11 = 0x00007ffff7a01a30 r12 = 0x0000000000000000 r13 = 0x00007fffffff6b38 r14 = 0x00007ffff7ffd000 r15 = 0x00005555563b9910 AddressSanitizer can not provide additional info.

This may be a bug in LSan, but regardless of whether it is eventually fixed, it is useful to work around it so that we stop seeing these false positives.

When trying to create a Unix socket in a path that exceeds the maximum socket name length we try to first change the directory into the parent folder before creating the socket to reduce the length of the name. When this fails we error out of `unix_sockaddr_init()` with an error code, which indicates to the caller that the context has not been initialized. Consequently, they don't release that context. This leads to a memory leak: when we have already populated the context with the original directory that we need to chdir(3p) back into, but then the chdir(3p) into the socket's parent directory fails, then we won't release the original directory's path. The leak is exposed by t0301, but only when running tests in a directory hierarchy whose path is long enough to make the socket name length exceed the maximum socket name length: Direct leak of 129 byte(s) in 1 object(s) allocated from: #0 0x5555555e85c6 in realloc.part.0 lsan_interceptors.cpp.o #1 0x55555590e3d6 in xrealloc ../wrapper.c:140:8 #2 0x5555558c8fc6 in strbuf_grow ../strbuf.c:114:2 #3 0x5555558cacab in strbuf_getcwd ../strbuf.c:605:3 #4 0x555555923ff6 in unix_sockaddr_init ../unix-socket.c:65:7 #5 0x555555923e42 in unix_stream_connect ../unix-socket.c:84:6 git#6 0x55555562a984 in send_request ../builtin/credential-cache.c:46:11 #7 0x55555562a89e in do_cache ../builtin/credential-cache.c:108:6 git#8 0x55555562a655 in cmd_credential_cache ../builtin/credential-cache.c:178:3 git#9 0x555555700547 in run_builtin ../git.c:480:11 git#10 0x5555556ff0e0 in handle_builtin ../git.c:740:9 git#11 0x5555556ffee8 in run_argv ../git.c:807:4 git#12 0x5555556fee6b in cmd_main ../git.c:947:19 git#13 0x55555593f689 in main ../common-main.c:64:11 git#14 0x7ffff7a2a1fb in __libc_start_call_main (/nix/store/h7zcxabfxa7v5xdna45y2hplj31ncf8a-glibc-2.40-36/lib/libc.so.6+0x2a1fb) (BuildId: 0a855678aa0cb573cecbb2bcc73ab8239ec472d0) git#15 0x7ffff7a2a2b8 in __libc_start_main@GLIBC_2.2.5 (/nix/store/h7zcxabfxa7v5xdna45y2hplj31ncf8a-glibc-2.40-36/lib/libc.so.6+0x2a2b8) (BuildId: 0a855678aa0cb573cecbb2bcc73ab8239ec472d0) git#16 0x5555555ad1d4 in _start (git+0x591d4) DEDUP_TOKEN: ___interceptor_realloc.part.0--xrealloc--strbuf_grow--strbuf_getcwd--unix_sockaddr_init--unix_stream_connect--send_request--do_cache--cmd_credential_cache--run_builtin--handle_builtin--run_argv--cmd_main--main--__libc_start_call_main--__libc_start_main@GLIBC_2.2.5--_start SUMMARY: LeakSanitizer: 129 byte(s) leaked in 1 allocation(s).

This leak is exposed by t9211, but only when run with Meson with the `-Db_sanitize=leak` option: Direct leak of 5 byte(s) in 1 object(s) allocated from: #0 0x5555555cfb93 in malloc (scalar+0x7bb93) #1 0x5555556b05c2 in do_xmalloc ../wrapper.c:55:8 #2 0x5555556b06c4 in do_xmallocz ../wrapper.c:89:8 #3 0x5555556b0656 in xmallocz ../wrapper.c:97:9 #4 0x5555556b0728 in xmemdupz ../wrapper.c:113:16 #5 0x5555556b07a7 in xstrndup ../wrapper.c:119:9 git#6 0x5555555d3a4b in remote_default_branch ../scalar.c:338:14 #7 0x5555555d20e6 in cmd_clone ../scalar.c:493:28 git#8 0x5555555d196b in cmd_main ../scalar.c:992:14 git#9 0x5555557c4059 in main ../common-main.c:64:11 git#10 0x7ffff7a2a1fb in __libc_start_call_main (/nix/store/h7zcxabfxa7v5xdna45y2hplj31ncf8a-glibc-2.40-36/lib/libc.so.6+0x2a1fb) (BuildId: 0a855678aa0cb573cecbb2bcc73ab8239ec472d0) git#11 0x7ffff7a2a2b8 in __libc_start_main@GLIBC_2.2.5 (/nix/store/h7zcxabfxa7v5xdna45y2hplj31ncf8a-glibc-2.40-36/lib/libc.so.6+0x2a2b8) (BuildId: 0a855678aa0cb573cecbb2bcc73ab8239ec472d0) git#12 0x555555592054 in _start (scalar+0x3e054) DEDUP_TOKEN: __interceptor_malloc--do_xmalloc--do_xmallocz--xmallocz--xmemdupz--xstrndup--remote_default_branch--cmd_clone--cmd_main--main--__libc_start_call_main--__libc_start_main@GLIBC_2.2.5--_start SUMMARY: LeakSanitizer: 5 byte(s) leaked in 1 allocation(s). As the `branch` variable may contain a string constant obtained from parsing command line arguments we cannot free the leaking variable directly. Instead, introduce a new `branch_to_free` variable that only ever gets assigned the allocated string and free that one to plug the leak. It is unclear why the leak isn't flagged when running the test via our Makefile. Signed-off-by: Patrick Steinhardt <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>

The GitHub's CI workflow uses 'actions/checkout@v4' to checkout the repository. This action defaults to using the GitHub REST API to obtain the repository if the `git` executable isn't available. The step to build Git in the GitHub workflow can be summarized as: ... - uses: actions/checkout@v4 #1 - run: ci/install-dependencies.sh #2 ... - run: sudo --preserve-env --set-home --user=builder ci/run-build-and-tests.sh #3 ... Step #1, clones the repository, since the `git` executable isn't present at this step, it uses GitHub's REST API to obtain a tar of the repository. Step #2, installs all dependencies, which includes the `git` executable. Step #3, sets up the build, which includes setting up meson in the meson job. At this point the `git` executable is present. This means while the `git` executable is present, the repository doesn't contain the '.git' folder. To keep both the CI's (GitLab and GitHub) behavior consistent and to ensure that the build is performed on a real-world scenario, install `git` before the repository is checked out. This ensures that 'actions/checkout@v4' will clone the repository instead of using a tarball. We also update the package cache while installing `git`, this is because some distros will fail to locate the package without updating the cache.

find_cfg_ent() allocates a struct reflog_expire_entry_option via FLEX_ALLOC_MEM and inserts it into a linked list in the reflog_expire_options structure. The entries in this list are never freed, resulting in a leak in cmd_reflog_expire and the gc reflog expire maintenance task: Direct leak of 39 byte(s) in 1 object(s) allocated from: #0 0x7ff975ee6883 in calloc (/lib64/libasan.so.8+0xe6883) #1 0x0000010edada in xcalloc ../wrapper.c:154 #2 0x000000df0898 in find_cfg_ent ../reflog.c:28 #3 0x000000df0898 in reflog_expire_config ../reflog.c:70 #4 0x00000095c451 in configset_iter ../config.c:2116 #5 0x0000006d29e7 in git_config ../config.h:724 git#6 0x0000006d29e7 in cmd_reflog_expire ../builtin/reflog.c:205 #7 0x0000006d504c in cmd_reflog ../builtin/reflog.c:419 git#8 0x0000007e4054 in run_builtin ../git.c:480 git#9 0x0000007e4054 in handle_builtin ../git.c:746 git#10 0x0000007e8a35 in run_argv ../git.c:813 git#11 0x0000007e8a35 in cmd_main ../git.c:953 git#12 0x000000441e8f in main ../common-main.c:9 git#13 0x7ff9754115f4 in __libc_start_call_main (/lib64/libc.so.6+0x35f4) git#14 0x7ff9754116a7 in __libc_start_main@@GLIBC_2.34 (/lib64/libc.so.6+0x36a7) git#15 0x000000444184 in _start (/home/jekeller/libexec/git-core/git+0x444184) Close this leak by adding a reflog_clear_expire_config() function which iterates the linked list and frees its elements. Call it upon exit of cmd_reflog_expire() and reflog_expire_condition(). Add a basic test which covers this leak. While at it, cover the functionality from commit commit 3cb22b8 (Per-ref reflog expiry configuration, 2008-06-15). We've had this support for years, but lacked any tests.
