The -d flag pre-dated git-clean's ability to have paths specified. As
such, the default for git-clean was to only remove untracked files in
the current directory, and -d existed to allow it to recurse into
subdirectories.
The interaction of paths and the -d option appears to not have been
carefully considered, as evidenced by numerous bugs and a dearth of
tests covering such pairings in the testsuite. The definition turns out
to be important, so let's look at some of the various ways one could
interpret the -d option:
A) Without -d, only look in subdirectories which contain tracked
files under them; with -d, also look in subdirectories which
are untracked for files to clean.
B) Without specified paths from the user for us to delete, we need to
have some kind of default, so...without -d, only look in
subdirectories which contain tracked files under them; with -d,
also look in subdirectories which are untracked for files to clean.
The important distinction here is that choice B says that the presence
or absence of '-d' is irrelevant if paths are specified. The logic
behind option B is that if a user explicitly asked us to clean a
specified pathspec, then we should clean anything that matches that
pathspec. Some examples may clarify. Should
git clean -f untracked_dir/file
remove untracked_dir/file or not? It seems crazy not to, but a strict
reading of option A says it shouldn't be removed. How about
git clean -f untracked_dir/file1 tracked_dir/file2
or
git clean -f untracked_dir_1/file1 untracked_dir_2/file2
? Should it remove either or both of these files? Should it require
multiple runs to remove both the files listed? (If this sounds like a
crazy question to even ask, see the commit message of "t7300: Add some
testcases showing failure to clean specified pathspecs" added earlier in
this patch series.) What if -ffd were used instead of -f -- should that
allow these to be removed? Should it take multiple invocations with
-ffd? What if a glob (such as '*tracked*') were used instead of
spelling out the directory names? What if the filenames involved globs,
such as
git clean -f '*.o'
or
git clean -f '*/*.o'
?
The current documentation actually suggests a definition that is
slightly different than choice A, and the implementation prior to this
series provided something radically different than either choices A or
B. (The implementation, though, was clearly just buggy). There may be
other choices as well. However, for almost any given choice of
definition for -d that I can think of, some of the examples above will
appear buggy to the user. The only case that doesn't have negative
surprises is choice B: treat a user-specified path as a request to clean
all untracked files which match that path specification, including
recursing into any untracked directories.
Change the documentation and basic implementation to use this
definition.
There were two regression tests that indirectly depended on the current
implementation, but neither was about subdirectory handling. These two
tests were introduced in commit 5b7570cfb41c ("git-clean: add tests for
relative path", 2008-03-07) which was solely created to add coverage for
the changes in commit fb328947c8e ("git-clean: correct printing relative
path", 2008-03-07). Both tests specified a directory that happened to
have an untracked subdirectory, but both were only checking that the
resulting printout of a file that was removed was shown with a relative
path. Update these tests appropriately.

The commit-graph feature began with a long list of planned
benefits, most of which are now complete. The future work
section has only a few items left.
As for making more algorithms aware of generation numbers,
some are only waiting for generation number v2 to ensure the
performance matches the existing behavior using commit date.
It is unlikely that we will ever send a commit-graph file
as part of the protocol, since we would need to verify the
data, and that is expensive. If we want to start trusting
remote content, then that item can be investigated again.
While there is more work to be done on the feature, having
a section of the docs devoted to a TODO list is wasteful and
hard to keep up-to-date.

git-send-email uses the TLS support in the Net::SMTP core module from

and libnet (3.01). Version numbers from commit:

If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.
So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.
If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.
For now though, let's just disable 'sparse:path' filters.

The availability of these pattern selections is not obvious from

Re-order the `git branch` synopsis to emphasise the `--list <pattern>`

Clarify that the `all/remotes` options require the --list if patterns
are to be used.
Add examples of listing remote tracking branches that match a pattern,
including `git for-each-ref` which has more options.
Improve the -a/-r warning message. The message confused this author
as the combined -a and -r options had not been given, though a pattern

option to enable a remote branch pattern selection.

Convert option_commit to tristate, representing the states of
'default/untouched', 'enabled-by-cli', 'disabled-by-cli'. With this in
place, check whether option_commit was enabled by cli when squashing a
merge. If so, error out, as this is not supported.
Previously, when --squash was supplied, 'option_commit' was silently
dropped. This could have been surprising to a user who tried to override
the no-commit behavior of squash using --commit explicitly.
Add a note to the --squash option for git-merge to clarify the
incompatibility, and add a test case to t7600-merge.sh

The descriptions of the GIT_TRACE2* environment variables link to the
technical docs for further details on the supported values. However,
a link like this only really works if the docs are viewed in a browser
and the full documentation is available. OTOH, in 'man git' there are
no links to conveniently click on, and distro-shipped git packages
tend to include only the man pages, while the technical docs and the
docs in html format are in a separate 'git-doc' package.
So let's describe the supported values to make the manpage more
self-contained, but still keep the references to the technical docs
because the details of the SID, and the JSON and perf output formats
are definitely beyond the scope of 'man git'.

For an environment variable that is supposed to be set by users, the
GIT_TR2* env vars are just too unclear, inconsistent, and ugly.
Most of the established GIT_* environment variables don't use
abbreviations, and in case of the few that do (GIT_DIR,
GIT_COMMON_DIR, GIT_DIFF_OPTS) it's quite obvious what the
abbreviations (DIR and OPTS) stand for. But what does TR stand for?
Track, traditional, trailer, transaction, transfer, transformation,
transition, translation, transplant, transport, traversal, tree,
trigger, truncate, trust, or ...?!
The trace2 facility, as the '2' suffix in its name suggests, is
supposed to eventually supercede Git's original trace facility. It's
reasonable to expect that the corresponding environment variables
follow suit, and after the original GIT_TRACE variables they are
called GIT_TRACE2; there is no such thing is 'GIT_TR'.
All trace2-specific config variables are, very sensibly, in the
'trace2' section, not in 'tr2'.
OTOH, we don't gain anything at all by omitting the last three
characters of "trace" from the names of these environment variables.
So let's rename all GIT_TR2* environment variables to GIT_TRACE2*,
before they make their way into a stable release.

There appears to be a bug in the toolchain generating manpages from
lettered lists. When a list is enumerated with letters, the resulting
nroff shows numbers instead. Mostly this is harmless, but in the case of
gitsubmodules, the paragraph following the list refers back to each
bullet by letter. As a result, reading this documentation via `man
gitsubmodules` is hard to parse - readers must infer that a bug exists
and a refers to 1, b refers to 2, and c refers to 3 in the list above.
The problem specifically was introduced in ad47194; previously rather
than generating numerated lists the bulleted area was entirely
monospaced in HTML and shown in plaintext in nroff.
The bug seems to exist in docbook-xml - I've reported it on May 1 via
the docbook-apps mail list - but for now it may make more sense to just
work around the issue.
