"git cvsserver" had a long-standing bug in its authentication code,
which has finally been corrected (it is unclear and is a separate
question if anybody is seriously using it, though).
* cb/cvsserver:
Documentation: cleanup git-cvsserver
git-cvsserver: protect against NULL in crypt(3)
git-cvsserver: use crypt correctly to compare password hashes

clone: handle unborn branch in bare repos
"git stash", where the tentative change involves changing a
directory to a file (or vice versa), was confused, which has been
corrected.

When "git am --abort" fails to abort correctly, it still exited
with exit status of 0, which has been corrected.
* en/am-abort-fix:
am: fix incorrect exit status on am fail to abort
t4151: add a few am --abort tests
git-am.txt: clarify --abort behavior
"git update-ref --stdin" failed to flush its output as needed,

The difftool dir-diff mode handles symlinks by replacing them with their
readlink(2) values. This allows diff tools to see changes to symlinks
as if they were regular text diffs with the old and new path values.
This is analogous to what "git diff" displays when symlinks change.
The temporary diff directories that are created initially contain
symlinks because they get checked-out using a temporary index that
retains the original symlinks as checked-in to the repository.
A bug was introduced when difftool was rewritten in C that made
difftool write the readlink(2) contents into the pointed-to file rather
than the symlink itself. The write was going through the symlink and
writing to its target rather than writing to the symlink path itself.
Replace symlinks with raw text files by unlinking the symlink path
before writing the readlink(2) content into them.
When 18ec800512 (difftool: handle modified symlinks in dir-diff mode,
2017-03-15) added handling for modified symlinks this bug got recorded
in the test suite. The tests included the pointed-to symlink target
paths. These paths were being reported because difftool was erroneously
writing to them, but they should have never been reported nor written.
Correct the modified-symlinks test cases by removing the target files
from the expected output.
Add a test to ensure that symlinks are written with the readlink(2)
values and that the target files contain their original content.

The "mode" word is useless in a call to open(2) that does not
create a new file. Such a call in the files backend of the ref
subsystem has been cleaned up.
* rs/no-mode-to-open-when-appending:
refs/files-backend: remove unused open mode parameter
The run-command API has been updated so that the callers can easily
ask the file descriptors open for packfiles to be closed immediately
before spawning commands that may trigger auto-gc.
* js/run-command-close-packs:
Close object store closer to spawning child processes
run_auto_maintenance(): implicitly close the object store
run-command: offer to close the object store before running
run-command: prettify the `RUN_COMMAND_*` flags
pull: release packs before fetching
commit-graph: when closing the graph, also release the slab
Various mergy operations have been prepared to work efficiently
with the sparse index.
* ds/mergies-with-sparse-index:
sparse-index: integrate with cherry-pick and rebase
sequencer: ensure full index if not ORT strategy
t1092: add cherry-pick, rebase tests
merge-ort: expand only for out-of-cone conflicts
merge: make sparse-aware with ORT
diff: ignore sparse paths in diffstat
In cone mode, the sparse-index code path learned to remove ignored
files (like build artifacts) outside the sparse cone, allowing the
entire directory outside the sparse cone to be removed, which is
especially useful when the sparse patterns change.
* ds/sparse-index-ignored-files:
sparse-checkout: clear tracked sparse dirs
sparse-index: add SPARSE_INDEX_MEMORY_ONLY flag
attr: be careful about sparse directories
sparse-checkout: create helper methods
sparse-index: use WRITE_TREE_MISSING_OK
sparse-index: silently return when cache tree fails
unpack-trees: fix nested sparse-dir search
sparse-index: silently return when not using cone-mode patterns
t7519: rewrite sparse index test

Makefile: add QUIET_GEN to "cscope" target
Makefile: move ".PHONY: cscope" near its target
Code clean-up around "git serve".
* ab/serve-cleanup:

submodule--helper: refactor resolve_relative_url() helper
submodule--helper: add options for compute_submodule_clone_url()
The order in which various files that make up a single (conceptual)
packfile has been reevaluated and straightened up. This matters in
correctness, as an incomplete set of files must not be shown to a
running Git.
* tb/pack-finalize-ordering:
pack-objects: rename .idx files into place after .bitmap files
pack-write: split up finish_tmp_packfile() function
builtin/index-pack.c: move `.idx` files into place last

developer: enable pedantic by default
win32: allow building with pedantic mode enabled
gettext: remove optional non-standard parens in N_() definition
The code to show progress indicator in a few code paths did not
cover between 0-100%, which has been corrected.
* ab/progress-users-adjust-counters:
entry: show finer-grained counter in "Filtering content" progress line
commit-graph: fix bogus counter in "Scanning merged commits" progress line
