"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.
* jt/interpret-branch-name-fallback:
wt-status: tolerate dangling marks
refs: move dwim_ref() to header file
sha1-name: replace unsigned int with option struct
The "--format=" option to the "for-each-ref" command and friends
learned a few more tricks, e.g. the ":short" suffix that applies to
"objectname" now also can be used for "parent", "tree", etc.

"git worktree" gained a "repair" subcommand to help users recover
after moving the worktrees or repository manually without telling
Git. Also, "git init --separate-git-dir" no longer corrupts
administrative data related to linked worktrees.
* es/worktree-repair:
init: make --separate-git-dir work from within linked worktree
init: teach --separate-git-dir to repair linked worktrees
worktree: teach "repair" to fix outgoing links to worktrees
worktree: teach "repair" to fix worktree back-links to main worktree
worktree: add skeleton "repair" command
When a packfile is removed by "git repack", multi-pack-index gets
cleared; the code was taught to do so less aggressively by first
checking if the midx actually refers to a pack that no longer
exists.
* tb/repack-clearing-midx:
midx: traverse the local MIDX first
builtin/repack.c: invalidate MIDX only when necessary
Yet another subcommand of "git submodule" is getting rewritten in C.
* ss/submodule-summary-in-c:
submodule: port submodule subcommand 'summary' from shell to C
t7421: introduce a test script for verifying 'summary' output
submodule: rename helper functions to avoid ambiguity
submodule: remove extra line feeds between callback struct and macro

REF_LOG_ONLY is used in the transaction preparation: if a symref is involved in
a transaction, the referent of the symref should be updated, and the symref
itself should only be updated in the reflog.
Other ref backends will need to duplicate this logic too, so move it to a
central place.

The "refuse --edit-description on unborn branch for now" test in t3200
switches to an orphan branch, causing subsequent git commands
referencing HEAD to fail. Avoid this side-effect by switching back to
master after the test finishes.
This has gone undetected, as the next affected test expects failure -
but it currently fails for the wrong reason.
Verbose output of the next test referencing HEAD,
"--merged is incompatible with --no-merged":
fatal: malformed object name HEAD
Which this commit corrects to:
error: option `no-merged' is incompatible with --merged

Emit byte-sized values using hashwrite_u8() instead of buffering them

map_refspec() either returns the passed in ref string or a detached
strbuf. This makes it hard for callers to release the possibly
allocated memory, and set_refspecs() consequently leaks it.
Let map_refspec() append any refspecs directly and release its own
strbufs after use. Rename it to refspec_append_mapped() and don't
return anything to reflect its increased responsibility.
set_refspecs() also leaks its strbufs. Do the same here and directly
call refspec_append() in each if branch instead of holding onto a
detached strbuf, then dispose of the allocated memory after use. We
need to add an else branch for the final call because all the other
conditional branches already add their formatted refspec now.
setup_push_upstream() and setup_push_current() forgot to release their
strbufs as well; plug these leaks, too, while at it.
None of these leaks were likely to impact users, because the number
and sizes of refspecs are usually small and the allocations are only
done once per program run. Clean them up nevertheless, as another
step on the long road towards zero memory leaks.

44c7e1a7e0 (mem-pool: use more standard initialization and finalization,
2020-08-15) moved the allocation of the mem-pool structure to callers.
It also added an allocation to load_cache_entries_threaded(), but for an
unrelated mem-pool. Fix that by allocating the correct one instead --
the one that is initialized two lines later.

Tools based on LibClang [1] can make use of a 'JSON Compilation
Database' [2] that keeps track of the exact options used to compile a set
of source files.
For example, clangd [3], which is a C language server protocol
implementation, can use a JSON compilation database to determine the
flags needed to compile a file so it can provide proper editor
integration. As a result, editors supporting the language server
protocol (such as VS Code, Emacs, or Vim, with suitable plugins) can
provide better searching, integration, and refactoring tools.
The Clang compiler can generate JSON fragments when compiling [4],
using the `-MJ` flag. These JSON fragments (one per compiled source
file) can then be concatenated to create the compilation database,
commonly called 'compile_commands.json'.
Add support to the Makefile for generating these JSON fragments as well
as the compilation database itself, if the environment variable
'GENERATE_COMPILATION_DATABASE' is set.
If this variable is set, check that $(CC) indeed supports the `-MJ`
flag, following what is done for automatic dependencies.
All JSON fragments are placed in the 'compile_commands/' directory, and
the compilation database 'compile_commands.json' is generated as a
dependency of the 'all' target using a `sed` invocation.
