* tl/gitweb-shorten-hashes-with-modes (2026-07-17) 1 commit
- gitweb: shorten index hashes with trailing file modes

A write file stream resource leak has been fixed as part of a code
cleanup.
The object ID shortening and linking in the 'commitdiff' view of
'gitweb' has been corrected to work even when the index line carries
a trailing file mode.

Various memory leaks in the Bloom-filter code paths that are exposed
when running tests with the 'GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS=1'
environment variable have been plugged.
The 'git repo info' command has been taught more keys to output
paths of various repository components (such as the working tree
root, superproject working tree, object database, etc.), supporting
both absolute and relative path formats.

* sk/userdiff-swift (2026-07-17) 1 commit
- userdiff: add support for Swift

A racy build failure under Meson has been corrected by ensuring that
the generated header file 'hook-list.h' is built before compiling
files in 'builtin_sources' that depend on it.
Userdiff patterns for Swift have been added, with support for
Swift-specific constructs such as attributes, modifiers, failable
initializers, and generics.

- object-file: fix memory leak in `force_object_loose()`
- odb: support setting mtime when writing objects
- odb: lift object existence check out of the "loose" backend
- odb: compute object hash in `odb_write_object_ext()`
- t/u-odb-inmemory: implement wrapper for writing objects
- odb: compute compat object ID in `odb_write_object_ext()`
- Merge branch 'jt/receive-pack-use-odb-transactions' into HEAD
(this branch uses jt/receive-pack-use-odb-transactions.)

The experimental 'git history' command has been taught a new 'drop'
subcommand to remove a commit, with its descendants replayed onto its
parent.
The logic to write loose objects has been refactored and moved from
'object-file.c' to the loose backend source file 'odb/source-loose.c',
making the loose backend more self-contained. This is achieved by
first refactoring 'force_object_loose()' to use generic ODB write
interfaces instead of loose-backend internals.

- rebase: remember fixup -c after skipping fixup/squash
- rebase -i: fix counting of fixups after rebase --skip

The 'whence' field in 'struct object_info' has been removed. The
backend-specific object information retrieval has been refactored into
an opt-in 'struct object_info_source' structure.
Two bugs in how 'git rebase' handles skipped 'fixup' and 'squash'
commands have been fixed. One bug caused an incorrect commit count
to be shown in the template message when multiple commands were
skipped, and another caused the editor not to be opened when the
final command in a chain containing 'fixup -c' was skipped.

- last-modified: keep per-path Bloom filters for wildcard pathspecs
- last-modified: check pathspec against Bloom filter first
- revision: expose check for paths maybe changed in Bloom filter
- revision: move bloom keyvec precondition into function

The 'git refs' toolbox has been extended with new 'create', 'delete',
'update', and 'rename' subcommands to create, delete, update, and
rename references, respectively.
The 'git last-modified' command has been optimized by using Bloom
filters. It now reuses revision walk filtering logic from 'git log'
to pre-filter commits, and maintains per-path Bloom filters even
when wildcard pathspecs are used.

- bisect: add --auto-reset to leave when done
- bisect: let bisect_reset() optionally check out quietly
- bisect: read run output from the open descriptor

The alignment of commit object name abbreviations in 'git blame'
output has been optimized to reserve a column for marks (caret,
question mark, or asterisk) only when such marks are actually shown.
The 'git bisect' command has been taught a '--auto-reset[=<where>]'
option that tells the command to automatically run 'git bisect reset'
to jump back to the original state or to the found culprit.

The UTF-8 precomposition wrapper on macOS has been updated to use a
flexible array member to represent the name of a directory entry,
preventing fortified libc checks from failing when the name is
reallocated to be larger than 'NAME_MAX' bytes.

The 'git_hash_*()' wrappers have been updated to be used consistently
across the codebase instead of direct calls to members of 'struct
git_hash_algo', and 'git_hash_discard()' has been made idempotent to
simplify cleanups.

Various code paths that initialize a cryptographic hash context but
bail out or finish without calling 'git_hash_final()' have been taught
to call 'git_hash_discard()' to release allocated resources, fixing
memory leaks when Git is built with non-default backends like
'OpenSSL' or 'libgcrypt'.
