2026-03-06Makefile: turn on NO_MMAP when building with LSanJeff King
The past few commits fixed some cases where we leak memory allocated by mmap(). Building with SANITIZE=leak doesn't detect these because it covers only heap buffers allocated by malloc(). But if we build with NO_MMAP, our compat mmap() implementation will allocate a heap buffer and pread() into it. And thus Lsan will detect these leaks for free. Using NO_MMAP is less performant, of course, since we have to use extra memory and read in the whole file, rather than faulting in pages from disk. But LSan builds are already slow, and this doesn't make them measurably worse. Getting extra coverage for our leak-checking is worth it.

2026-03-06object-file: fix mmap() leak in odb_source_loose_read_object_stream()Jeff King
We mmap() a loose object file, storing the result in the local variable "mapped", which is eventually assigned into our stream struct as "st.mapped". If we hit an error, we jump to an error label which does: munmap(st.mapped, st.mapsize); to clean up. But this is wrong; we don't assign st.mapped until the end of the function, after all of the "goto error" jumps. So this munmap() is never cleaning up anything (st.mapped is always NULL, because we initialize the struct with calloc). Instead, we should feed the local variable to munmap(). This leak is due to 595296e124 (streaming: allocate stream inside the backend-specific logic, 2025-11-23), which introduced the local variable. Before that, we assigned the mmap result directly into st.mapped. It was probably switched there so that we do not have to allocate/free the struct when the map operation fails (e.g., because we don't have the loose object). Before that commit, the struct was passed in from the caller, so there was no allocation at all. You can see the leak in the test suite by building with: make SANITIZE=leak NO_MMAP=1 CC=clang and running t1060. We need NO_MMAP so that the mmap() is backed by an actual malloc(), which allows LSan to detect it. And the leak seems not to be detected when compiling with gcc, probably due to some internal compiler decisions about how the stack memory is written.

2026-03-06format-patch: add commitListFormat configMirko Faina
Using "--cover-letter" we can tell format-patch to generate a cover letter, in this cover letter there's a list of commits included in the patch series and the format is specified by the "--cover-letter-format" option. Would be useful if this format could be configured from the config file instead of always needing to pass it from the command line. Teach format-patch how to read the format spec for the cover letter from the config files. The variable it should look for is called format.commitListFormat. Possible values: - commitListFormat is set but no string is passed: it will default to "[%(count)/%(total)] %s" - if a string is passed: will use it as a format spec. Note that this is either "shortlog" or a format spec prefixed by "log:" e.g."log:%s (%an)" - if commitListFormat is not set: it will default to the shortlog format.

2026-03-06format-patch: add ability to use alt cover formatMirko Faina
Often when sending patch series there's a need to clarify to the reviewer what's the purpose of said series, since it might be difficult to understand it from reading the commits messages one by one. "git format-patch" provides the useful "--cover-letter" flag to declare if we want it to generate a template for us to use. By default it will generate a "git shortlog" of the changes, which developers find less useful than they'd like, mainly because the shortlog groups commits by author, and gives no obvious chronological order. Give format-patch the ability to specify an alternative format spec through the "--cover-letter-format" option. This option either takes "shortlog", which is the current format, or a format spec prefixed with "log:". Example: git format-patch --cover-letter \ --cover-letter-format="log:[%(count)/%(total)] %s (%an)" HEAD~3 [1/3] this is a commit summary (Mirko Faina) [2/3] this is another commit summary (Mirko Faina) ...

In many commands we can customize the output through the "--format" or the "--pretty" options. This patch adds two new placeholders used mainly when there's a range of commits that we want to show. Currently these two placeholders are not usable as they're coupled with the rev_info->nr and rev_info->total fields, fields that are used only by the format-patch numbered email subjects.

2026-03-06Documentation: extend guidance for submitting patchesJustin Tobler
Before submitting patches on the mailing list, it is often a good idea to check for previous related discussions or if similar work is already in progress. This enables better coordination amongst contributors and could avoid duplicating work. Additionally, it is often recommended to give reviewers some time to reply to a patch series before sending new versions. This helps collect broader feedback and reduces unnecessary churn from rapid rerolls. Document this guidance in "Documentation/SubmittingPatches" accordingly.

2026-03-06pack-revindex: avoid double-loading .rev filesJeff King
The usual entry point for loading the pack revindex is the load_pack_revindex() function. It returns immediately if the packed_git has a non-NULL revindex or revindex data field (representing an in-memory or mmap'd .rev file, respectively), since the data is already loaded. But in 5a6072f631 (fsck: validate .rev file header, 2023-04-17) the fsck code path switched to calling load_pack_revindex_from_disk() directly, since it wants to check the on-disk data (if there is any). But that function does _not_ check to see if the data has already been loaded; it just maps the file, overwriting the revindex_map pointer (and pointing revindex_data inside that map). And in that case we've leaked the mmap() pointed to by revindex_map (if it was non-NULL). This usually doesn't happen, since fsck wouldn't need to load the revindex for any reason before we get to these checks. But there are some cases where it does. For example, is_promisor_object() runs odb_for_each_object() with the PACK_ORDER flag, which uses the revindex. This happens a few times in our test suite, but SANITIZE=leak doesn't detect it because we are leaking an mmap(), not a heap-allocated buffer from malloc(). However, if you build with NO_MMAP, then our compat mmap will read into a heap buffer instead, and LSan will complain. This causes failures in t5601, t0410, t5702, and t5616. We can fix it by checking for existing revindex_data when loading from disk. This is redundant when we're called from load_pack_revindex(), but it's a cheap check. The alternative is to teach check_pack_rev_indexes() in fsck to skip the load, but that seems messier; it doesn't otherwise know about internals like revindex_map and revindex_data.

2026-03-06check_connected(): fix leak of pack-index mmapJeff King
Since c6807a40dc (clone: open a shortcut for connectivity check, 2013-05-26), we may open a one-off packed_git struct to check what's in the pack we just received. At the end of the function we throw away the struct (rather than linking it into the repository struct as usual). We used to leak the struct until dd4143e7bf (connected.c: free the "struct packed_git", 2022-11-08), which calls free(). But that's not sufficient; inside the struct we'll have mmap'd the pack idx data from disk, which needs an munmap() call. Building with SANITIZE=leak doesn't detect this, because we are leaking our own mmap(), and it only finds heap allocations from malloc(). But if we use our compat mmap implementation like this: make NO_MMAP=MapsBecomeMallocs SANITIZE=leak then LSan will notice the leak, because now it's a regular heap buffer allocated by malloc(). We can fix it by calling close_pack(), which will free any associated memory. Note that we need to check for NULL ourselves; unlike free(), it is not safe to pass a NULL pointer to close_pack().

2026-03-06check_connected(): delay opening new_packJeff King
In check_connected(), if the transport tells us we got a single packfile that has already been verified as self-contained and connected, then we can skip checking connectivity for any tips that are mentioned in that pack. This goes back to c6807a40dc (clone: open a shortcut for connectivity check, 2013-05-26). We don't need to open that pack until we are about to start sending oids to our child rev-list process, since that's when we check whether they are in the self-contained pack. Let's push the opening of that pack further down in the function. That saves us from having to clean it up when we leave the function early (and by the time have opened the rev-list process, we never leave the function early, since we have to clean up the child process).

As the trailers are no longer added in a separate process and trailer_config_init() die()s on missing config values it is called early on in cmd_commit() and cmd_tag() so that they die() early before writing the message file.

2026-03-05odb/source: make `read_object_info()` function pluggablePatrick Steinhardt
Introduce a new callback function in `struct odb_source` to make the function pluggable. Note that this function is a bit less straight-forward to convert compared to the other functions. The reason here is that the logic to read an object is: 1. We try to read the object. If it exists we return it. 2. If the object does not exist we reprepare the object database source. 3. We then try reading the object info a second time in case the reprepare caused it to appear. The second read is only supposed to happen for the packfile store though, as reading loose objects is not impacted by repreparing the object database. Ideally, we'd just move this whole logic into the ODB source. But that's not easily possible because we try to avoid the reprepare unless really required, which is after we have found out that no other ODB source contains the object, either. So the logic spans across multiple ODB sources, and consequently we cannot move it into an individual source. Instead, introduce a new flag `OBJECT_INFO_SECOND_READ` that tells the backend that we already tried to look up the object once, and that this time around the ODB source should try to find any new objects that may have surfaced due to an on-disk change. With this flag, the "files" backend can trivially skip trying to re-read the object as a loose object. Furthermore, as we know that we only try the second read via the packfile store, we can skip repreparing loose objects and only reprepare the packfile store.

2026-03-05odb: move reparenting logic into respective subsystemsPatrick Steinhardt
The primary object database source may be initialized with a relative path. When the process changes its current working directory we thus have to update this path and have it point to the same path, but relative to the new working directory. This logic is handled in the object database layer. It consists of three steps: 1. We undo any potential temporary object directory, which are used for transactions. This is done so that we don't end up modifying the temporary object database source that got applied for the transaction. 2. We then iterate through the non-transactional sources and reparent their respective paths. 3. We reapply the temporary object directory, but update its path. All of this logic is heavily tied to how the object database source handles paths in the first place. It's an internal implementation detail, and as sources may not even use an on-disk path at all it is not a mechanism that applies to all potential sources. Refactor the code so that the logic to reparent the sources is hosted by the "files" source and the temporary object directory subsystems, respectively. This logic is easier to reason about, but it also ensures that this logic is handled at the correct level.

2026-03-05odb: embed base source in the "files" backendPatrick Steinhardt
The "files" backend is implemented as a pointer in the `struct odb_source`. This contradicts our typical pattern for pluggable backends like we use it for example in the ref store or for object database streams, where we typically embed the generic base structure in the specialized implementation. This pattern has a couple of small benefits: - We avoid an extra allocation. - We hide implementation details in the generic structure. - We can easily downcast from a generic backend to the specialized structure and vice versa because the offsets are known at compile time. - It becomes trivial to identify locations where we depend on backend specific logic because the cast needs to be explicit. Refactor our "files" object database source to do the same and embed the `struct odb_source` in the `struct odb_source_files`. There are still a bunch of sites in our code base where we do have to access internals of the "files" backend. The intent is that those will go away over time, but this will certainly take a while. Meanwhile, provide a `odb_source_files_downcast()` function that can convert a generic source into a "files" source. As we only have a single source the downcast succeeds unconditionally for now. Eventually though the intent is to make the cast `BUG()` in case the caller requests to downcast a non-"files" backend to a "files" backend.

In d0cec08d70 (utf8.c: prepare workaround for iconv under macOS 14/15, 2026-01-12) we have introduced a new workaround for a broken version of libiconv on macOS. This workaround has for now only been wired up for our Makefile, so using Meson with such a broken version will fail. We can rather easily detect the broken behaviour. Some encodings have different modes that can be switched to via an escape sequence. In the case of ISO-2022-JP this can be done via "<Esc>$B" and "<Esc>(J" to switch between ASCII and JIS modes. The bug now triggers when one does multiple calls to iconv(3p) to convert a string piece by piece, where the first call enters JIS mode. The second call forgets about the fact that it is still in JIS mode, and consequently it will incorrectly treat the input as ASCII, and thus the produced output is of course garbage. Wire up a test that exercises this in Meson and, if it fails, set the `ICONV_RESTART_RESET` define. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
