The loose object cache used to optimize existence look-up has been
updated.
* rs/loose-object-cache-perffix:
object-store: retire odb_load_loose_cache()
object-store: use one oid_array per subdirectory for loose cache
object-store: factor out odb_clear_loose_cache()
object-store: factor out odb_loose_cache()
An inherently racy test that caused intermittent failures has been
removed.
* tg/t5570-drop-racy-test:
Revert "t/lib-git-daemon: record daemon log"
t5570: drop racy test
Earlier we added "-Wformat-security" to developer builds, assuming
that "-Wall" (which includes "-Wformat" which in turn is required
to use "-Wformat-security") is always in effect. This is not true
when config.mak.autogen is in use, unfortunately. This has been
fixed by unconditionally adding "-Wall" to developer builds.
* jk/dev-build-format-security:
config.mak.dev: add -Wall, primarily for -Wformat, to help autoconf users
"git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.
Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.
* so/cherry-pick-always-allow-m1:
t3506: validate '-m 1 -ff' is now accepted for non-merge commits
t3502: validate '-m 1' argument is now accepted for non-merge commits
cherry-pick: do not error on non-merge commits when '-m 1' is specified
t3510: stop using '-m 1' to force failure mid-sequence of cherry-picks
"git worktree remove" and "git worktree move" refused to work when
there is a submodule involved. This has been loosened to ignore
uninitialized submodules.
* nd/worktree-remove-with-uninitialized-submodules:
worktree: allow to (re)move worktrees with uninitialized submodules
The test suite tried to see if it is run under bash, but the check
itself failed under some other implementations of shell (notably
under NetBSD). This has been corrected.
* sg/test-bash-version-fix:
test-lib: check Bash version for '-x' without using shell arrays
Portability updates for the HPE NonStop platform.
* rb/hpe:
compat/regex/regcomp.c: define intptr_t and uintptr_t on NonStop
git-compat-util.h: add FLOSS headers for HPE NonStop
config.mak.uname: support for modern HPE NonStop config.
transport-helper: drop read/write errno checks
transport-helper: use xread instead of read
With zsh, "git cmd path<TAB>" was completed to "git cmd path name"
when the completed path has a special character like SP in it,
without any attempt to keep "path name" a single filename. This
has been fixed to complete it to "git cmd path\ name" just like
Bash completion does.
* cy/zsh-completion-SP-in-path:
completion: treat results of git ls-tree as file paths
zsh: complete unquoted paths with spaces correctly
The core.worktree setting in a submodule repository should not be
pointing at a directory when the submodule loses its working tree
(e.g. getting deinit'ed), but the code did not properly maintain
this invariant.
* sb/submodule-unset-core-worktree-when-worktree-is-lost:
submodule deinit: unset core.worktree
submodule--helper: fix BUG message in ensure_core_worktree
submodule: unset core.worktree if no working tree is present
submodule update: add regression test with old style setups
Some of the documentation pages formatted incorrectly with
Asciidoctor, which have been fixed.
* ma/asciidoctor:
git-status.txt: render tables correctly under Asciidoctor
Documentation: do not nest open blocks
git-column.txt: fix section header
"git stripspace" should be usable outside a git repository, but
under the "-s" or "-c" mode, it didn't.
* jn/stripspace-wo-repository:
stripspace: allow -s/-c outside git repository
"git submodule update" ought to use a single job unless asked, but
by mistake used multiple jobs, which has been fixed.
* sb/submodule-fetchjobs-default-to-one:
submodule update: run at most one fetch job unless otherwise set
"git log -G<regex>" looked for a hunk in the "git log -p" patch
output that contained a string that matches the given pattern.
Optimize this code to ignore binary files, which by default will
not show any hunk that would match any pattern (unless textconv or
the --text option is in effect, that is).
* tb/log-G-binary:
log -G: ignore binary files
Lines that begin with a certain keyword that come over the wire, as
well as lines that consist only of one of these keywords, ought to
be painted in color for easier eyeballing, but the latter was
broken ever since the feature was introduced in 2.19, which has
been corrected.
* hn/highlight-sideband-keywords:
sideband: color lines with keyword only
"git checkout [<tree-ish>] path..." learned to report the number of
paths that have been checked out of the index or the tree-ish,
which gives it the same degree of noisy-ness as the case in which
the command checks out a branch.
* nd/checkout-noisy:
t0027: squelch checkout path run outside test_expect_* block
checkout: print something when checking out paths
The traversal over tree objects has learned to honor
":(attr:label)" pathspec match, which has been implemented only for
enumerating paths on the filesystem.
* nd/attr-pathspec-in-tree-walk:
tree-walk: support :(attr) matching
dir.c: move, rename and export match_attrs()
pathspec.h: clean up "extern" in function declarations
tree-walk.c: make tree_entry_interesting() take an index
tree.c: make read_tree*() take 'struct repository *'
"git rev-list --exclude-promisor-objects" had to take an object
that does not exist locally (and is lazily available) from the
command line without barfing, but the code dereferenced NULL.
* md/list-lazy-objects-fix:
list-objects.c: don't segfault for missing cmdline objects

Inline odb_load_loose_cache() into its only remaining caller,
odb_loose_cache(). The latter offers a nicer interface for loading the
cache, as it doesn't require callers to deal with fanout directory
numbers directly.

The loose objects cache is filled one subdirectory at a time as needed.
It is stored in an oid_array, which has to be resorted after each add
operation. So when querying a wide range of objects, the partially
filled array needs to be resorted up to 255 times, which takes over 100
times longer than sorting once.
Use one oid_array for each subdirectory. This ensures that entries have
to only be sorted a single time. It also avoids eight binary search
steps for each cache lookup as a small bonus.
The cache is used for collision checks for the log placeholders %h, %t
and %p, and we can see the change speeding them up in a repository with
ca. 100 objects per subdirectory:
$ git count-objects
26733 objects, 68808 kilobytes

Add and use a function for loading the entries of a loose object
subdirectory for a given object ID. It frees callers from deriving the
fanout key; they can use the returned oid_array reference for lookups or
forward range scans.
