2025-06-24test-lib: teach test_seq the -f optionJeff King9-62/+32
The "seq" tool has a "-f" option to produce printf-style formatted lines. Let's teach our test_seq helper the same trick. This lets us get rid of some shell loops in test snippets (which are particularly verbose in our test suite because we have to "|| return 1" to keep the &&-chain going). This converts a few call-sites I found by grepping around the test suite. A few notes on these: - In "seq", the format specifier is a "%g" float. Since test_seq only supports integers, I've kept the more natural "%d" (which is what these call sites were using already). - Like "seq", test_seq automatically adds a newline to the specified format. This is what all callers are doing already except for t0021, but there we do not care about the exact format. We are just trying to printf a large number of bytes to a file. It's not worth complicating other callers or adding an option to avoid the newline in that caller. - Most conversions are just replacing a shell loop (which does get rid of an extra fork, since $() requires a subshell). In t0612 we can replace an awk invocation, which I think makes the end result more readable, as there's less quoting. - In t7422 we can replace one loop, but sadly we have to leave the loop directly above it. This is because that earlier loop wants to include the seq value twice in the output, which test_seq does not support (nor does regular seq). If you run: test_seq -f "foo-%d %d" 10 the second "%d" will always be the empty string. You might naively think that test_seq could add some extra arguments, like: # 3 ought to be enough for anyone... printf "$fmt\n" "$i "$i" $i" but that just triggers printf to format multiple lines, one per extra set of arguments. So we'd have to actually parse the format string, figure out how many "%" placeholders are there, and then feed it that many instances of the sequence number. The complexity isn't worth it.

2025-06-23submodule: look up remotes by URL firstJacob Keller4-1/+73
The get_default_remote_submodule() function performs a lookup to find the appropriate remote to use within a submodule. The function first checks to see if it can find the remote for the current branch. If this fails, it then checks to see if there is exactly one remote. It will use this, before finally falling back to "origin" as the default. If a user happens to rename their default remote from origin, either manually or by setting something like clone.defaultRemoteName, this fallback will not work. In such cases, the submodule logic will try to use a non-existent remote. This usually manifests as a failure to trigger the submodule update. The parent project already knows and stores the submodule URL in either .gitmodules or its .git/config. Add a new repo_remote_from_url() helper which will iterate over all the remotes in a repository and return the first remote which has a matching URL. Refactor get_default_remote_submodule to find the submodule and get its URL. If a valid URL exists, first try to obtain a remote using the new repo_remote_from_url(). Fall back to the repo_default_remote() otherwise. The fallback logic is kept in case for some reason the user has manually changed the URL within the submodule. Additionally, we still try to use a remote rather than directly passing the URL in the fetch_in_submodule() logic. This ensures that an update will properly update the remote refs within the submodule as expected, rather than just fetching into FETCH_HEAD.

2025-06-23submodule--helper: improve logic for fallback remote nameJacob Keller4-46/+57
The repo_get_default_remote() function in submodule--helper currently tries to figure out the proper remote name to use for a submodule based on a few factors. First, it tries to find the remote for the currently checked out branch. This works if the submodule is configured to checkout to a branch instead of a detached HEAD state. In the detached HEAD state, the code calls back to using "origin", on the assumption that this is the default remote name. Some users may change this, such as by setting clone.defaultRemoteName, or by changing the remote name manually within the submodule repository. As a first step to improving this situation, refactor to reuse the logic from remotes_remote_for_branch(). This function uses the remote from the branch if it has one. If it doesn't then it checks to see if there is exactly one remote. It uses this remote first before attempting to fall back to "origin". To allow using this helper function, introduce a repo_default_remote() helper to remote.c which takes a repository structure. This helper will load the remote configuration and get the "HEAD" branch. Then it will call remotes_remote_for_branch to find the default remote. Replace calls of repo_get_default_remote() with the calls to this new function. To maintain consistency with the existing callers, continue copying the returned string with xstrdup. This isn't a perfect solution for users who change remote names, but it should help in cases where the remote name is changed but users haven't added any additional remotes.

2025-06-23remote: remove the_repository from some functionsJacob Keller1-30/+28
The remotes_remote_get_1 (and its caller, remotes_remote_get, have an implicit dependency on the_repository due to calling read_branches_file() and read_remotes_file(), both of which use the_repository. The branch_get() function calls set_merge() which has an implicit dependency on the_repository as well. Because of this use of the_repository, the helper functions cannot be used in code paths which operate on other repositories. A future refactor of the submodule--helper will want to make use of some of these functions. Refactor to break the dependency by passing struct repository *repo instead of struct remote_state *remote_state in a few places. The public callers and many other helper functions still depend on the_repository. A repo-aware function will be exposed in a following change for git submodule--helper.

Both submodule--helper.c and submodule-config.c have an implementation of starts_with_dot_slash and starts_with_dot_dot_slash. The dir.h header has starts_with_dot(_dot)_slash_native, which sets PATH_MATCH_NATIVE. Move the helpers to dir.h as static inlines. I thought about renaming them to postfix with _platform but that felt too long and ugly. On the other hand it might be slightly confusing with _native.

2025-06-23remote: remove branch->merge_name and fix branch_release()Jacob Keller4-21/+33
The branch structure has both branch->merge_name and branch->merge for tracking the merge information. The former is allocated by add_merge() and stores the names read from the configuration file. The latter is allocated by set_merge() which is called by branch_get() when an external caller requests a branch. This leads to the confusing situation where branch->merge_nr tracks both the size of branch->merge (once its allocated) and branch->merge_name. The branch_release() function incorrectly assumes that branch->merge is always set when branch->merge_nr is non-zero, and can potentially crash if read_config() is called without branch_get() being called on every branch. In addition, branch_release() fails to free some of the memory associated with the structure including: * Failure to free the refspec_item containers in branch->merge[i] * Failure to free the strings in branch->merge_name[i] * Failure to free the branch->merge_name parent array. The set_merge() function sets branch->merge_nr to 0 when there is no valid remote_name, to avoid external callers seeing a non-zero merge_nr but a NULL merge array. This results in failure to release most of the merge data as well. These issues could be fixed directly, and indeed I initially proposed such a change at [1] in the past. While this works, there was some confusion during review because of the inconsistencies. Instead, its time to clean up the situation properly. Remove branch->merge_name entirely. Instead, allocate branch->merge earlier within add_merge() instead of within set_merge(). Instead of having set_merge() copy from merge_name[i] to merge[i]->src, just have add_merge() directly initialize merge[i]->src. Modify the add_merge() to call xstrdup() itself, instead of having the caller of add_merge() do so. This makes it more obvious which code owns the memory. Update all callers which use branch->merge_name[i] to use branch->merge[i]->src instead. Add a merge_clear() function which properly releases all of the merge-related memory, and which sets branch->merge_nr to zero. Use this both in branch_release() and in set_merge(), fixing the leak when set_merge() finds no valid remote_name. Add a set_merge variable to the branch structure, which indicates whether set_merge() has been called. This replaces the previous use of a NULL check against the branch->merge array. With these changes, the merge array is always allocated when merge_nr is non-zero. This use of refspec_item to store the names should be safe. External callers should be using branch_get() to obtain a pointer to the branch, which will call set_merge(), and the callers internal to remote.c already handle the partially initialized refpsec_item structure safely. This end result is cleaner, and avoids duplicating the merge names twice.

2025-06-23repack: exclude cruft pack(s) from the MIDX where possibleTaylor Blau3-20/+319
In ddee3703b3 (builtin/repack.c: add cruft packs to MIDX during geometric repack, 2022-05-20), repack began adding cruft pack(s) to the MIDX with '--write-midx' to ensure that the resulting MIDX was always closed under reachability in order to generate reachability bitmaps. While the previous patch added the '--stdin-packs=follow' option to pack-objects, it is not yet on by default. Given that, suppose you have a once-unreachable object packed in a cruft pack, which later becomes reachable from one or more objects in a geometrically repacked pack. That once-unreachable object *won't* appear in the new pack, since the cruft pack was not specified as included or excluded when the geometrically repacked pack was created with 'pack-objects --stdin-packs' (*not* '--stdin-packs=follow', which is not on). If that new pack is included in a MIDX without the cruft pack, then trying to generate bitmaps for that MIDX may fail. This happens when the bitmap selection process picks one or more commits which reach the once-unreachable objects. To mitigate this failure mode, commit ddee3703b3 ensures that the MIDX will be closed under reachability by including cruft pack(s). If cruft pack(s) were not included, we would fail to generate a MIDX bitmap. But ddee3703b3 alludes to the fact that this is sub-optimal by saying [...] it's desirable to avoid including cruft packs in the MIDX because it causes the MIDX to store a bunch of objects which are likely to get thrown away. , which is true, but hides an even larger problem. If repositories rarely prune their unreachable objects and/or have many of them, the MIDX must keep track of a large number of objects which bloats the MIDX and slows down object lookup. This is doubly unfortunate because the vast majority of objects in cruft pack(s) are unlikely to be read. But any object lookups that go through the MIDX must binary search over them anyway, slowing down object lookups using the MIDX. This patch causes geometrically-repacked packs to contain a copy of any once-unreachable object(s) with 'git pack-objects --stdin-packs=follow', allowing us to avoid including any cruft packs in the MIDX. This is because a sequence of geometrically-repacked packs that were all generated with '--stdin-packs=follow' are guaranteed to have their union be closed under reachability. Note that you cannot guarantee that a collection of packs is closed under reachability if not all of them were generated with "following" as above. One tell-tale sign that not all geometrically-repacked packs in the MIDX were generated with "following" is to see if there is a pack in the existing MIDX that is not going to be somehow represented (either verbatim or as part of a geometric rollup) in the new MIDX. If there is, then starting to generate packs with "following" during geometric repacking won't work, since it's open to the same race as described above. But if you're starting from scratch (e.g., building the first MIDX after an all-into-one '--cruft' repack), then you can guarantee that the union of subsequently generated packs from geometric repacking *is* closed under reachability. (One exception here is when "starting from scratch" results in a noop repack, e.g., because the non-cruft pack(s) in a repository already form a geometric progression. Since we can't tell whether or not those were generated with '--stdin-packs=follow', they may depend on once-unreachable objects, so we have to include the cruft pack in the MIDX in this case.) Detect when this is the case and avoid including cruft packs in the MIDX where possible. The existing behavior remains the default, and the new behavior is available with the config 'repack.midxMustIncludeCruft' set to 'false'.

2025-06-23pack-objects: introduce '--stdin-packs=follow'Taylor Blau3-23/+193
When invoked with '--stdin-packs', pack-objects will generate a pack which contains the objects found in the "included" packs, less any objects from "excluded" packs. Packs that exist in the repository but weren't specified as either included or excluded are in practice treated like the latter, at least in the sense that pack-objects won't include objects from those packs. This behavior forces us to include any cruft pack(s) in a repository's multi-pack index for the reasons described in ddee3703b3 (builtin/repack.c: add cruft packs to MIDX during geometric repack, 2022-05-20). The full details are in ddee3703b3, but the gist is if you have a once-unreachable object in a cruft pack which later becomes reachable via one or more commits in a pack generated with '--stdin-packs', you *have* to include that object in the MIDX via the copy in the cruft pack, otherwise we cannot generate reachability bitmaps for any commits which reach that object. Note that the traversal here is best-effort, similar to the existing traversal which provides name-hash hints. This means that the object traversal may hand us back a blob that does not actually exist. We *won't* see missing trees/commits with 'ignore_missing_links' because: - missing commit parents are discarded at the commit traversal stage by revision.c::process_parents() - missing tag objects are discarded by revision.c::handle_commit() - missing tree objects are discarded by the list-objects code in list-objects.c::process_tree() But we have to handle potentially-missing blobs specially by making a separate check to ensure they exist in the repository. Failing to do so would mean that we'd add an object to the packing list which doesn't actually exist, rendering us unable to write out the pack. This prepares us for new repacking behavior which will "resurrect" objects found in cruft or otherwise unspecified packs when generating new packs. In the context of geometric repacking, this may be used to maintain a sequence of geometrically-repacked packs, the union of which is closed under reachability, even in the case described earlier.

2025-06-23pack-objects: perform name-hash traversal for unpacked objectsTaylor Blau1-8/+12
With '--unpacked', pack-objects adds loose objects (which don't appear in any of the excluded packs from '--stdin-packs') to the output pack without considering them as reachability tips for the name-hash traversal. This was an oversight in the original implementation of '--stdin-packs', since the code which enumerates and adds loose objects to the output pack (`add_unreachable_loose_objects()`) did not have access to the 'rev_info' struct found in `read_packs_list_from_stdin()`. Excluding unpacked objects from that traversal doesn't affect the correctness of the resulting pack, but it does make it harder to discover good deltas for loose objects. Now that the 'rev_info' struct is declared outside of `read_packs_list_from_stdin()`, we can pass it to `add_objects_in_unpacked_packs()` and add any loose objects as tips to the above-mentioned traversal, in theory producing slightly tighter packs as a result.

A future commit will change the purpose of this reachability traversal to find and pack objects which are reachable from commits in the input packs, but are packed in an unknown (not included nor excluded) pack. Extract the code which initializes and performs the reachability traversal to take place in the caller, not the callee, which prepares us to share this code for the '--unpacked' case (see the function add_unreachable_loose_objects() for more details).

We could switch both instances of "$i" to "%d" (and pass $i twice). But that makes the line even longer. Let's just keep interpolating the value in the string, and drop the confusing extra "$i" argument.

A sample output looks like this when run against a Gmail server: Fetching the list of available folders... * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasChildren \Noselect) "/" "[Gmail]" * LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail" * LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts" * LIST (\HasNoChildren \Important) "/" "[Gmail]/Important" * LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail" * LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam" * LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred" * LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash" For OpenSSL, this is achived by running the 'IMAP LIST' command and parsing the response. This command is specified in RFC6154: https://datatracker.ietf.org/doc/html/rfc6154#section-5.1 For libcurl, the example code published in the libcurl documentation is used to implement this functionality: https://curl.se/libcurl/c/imap-list.html Signed-off-by: Aditya Garg <gargaditya08@live.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-06-20imap-send: enable specifying the folder using the command lineAditya Garg3-7/+23
Some users may very often want to imap-send messages to a folder other than the default set in the config. Add a command line argument for the same.

2025-06-20imap-send: add PLAIN authentication method to OpenSSLAditya Garg2-3/+61
The current implementation for PLAIN in imap-send works just fine if using curl, but if attempted to use for OpenSSL, it is treated as an invalid mechanism. The default implementation for OpenSSL is IMAP LOGIN command rather than AUTH PLAIN. Since AUTH PLAIN is still used today by many email providers in form of app passwords, lets add an implementation that can use AUTH PLAIN if specified.

2025-06-20imap-send: add support for OAuth2.0 authenticationAditya Garg3-13/+183
OAuth2.0 is a new way of authentication supported by various email providers these days. OAUTHBEARER and XOAUTH2 are the two most common mechanisms used for OAuth2.0. OAUTHBEARER is described in RFC5801[1] and RFC7628[2], whereas XOAUTH2 is Google's proprietary mechanism (See [3]).

2025-06-20imap-send: gracefully fail if CRAM-MD5 authentication is requested without ↵Aditya Garg1-27/+39
OpenSSL Unlike PLAIN, XOAUTH2 and OAUTHBEARER, CRAM-MD5 authentication is not supported by libcurl and requires OpenSSL. If the user tries to use CRAM-MD5 authentication without OpenSSL, the previous behaviour was to attempt to authenticate and fail with a die(error). Handle this in a better way by first checking if OpenSSL is available and then attempting to authenticate. If OpenSSL is not available, print an error message and exit gracefully.

2025-06-20imap-send: fix bug causing cfg->folder being set to NULLAditya Garg1-4/+4
6d1f198f34 (imap-send: fix leaking memory in `imap_server_conf`, 2024-06-07) resulted a change in static int git_imap_config which resulted in cfg->folder being incorrectly set to NULL in case imap.user, imap.pass, imap.tunnel and imap.authmethod were defined. Because of this, since Git 2.46.0, git-imap-send is not usable at all. The bug seems to have been unnoticed for a long time, likely due to better options like git-send-email.
