archive: support compression levels beyond 9
Compression programs like zip, gzip, bzip2 and xz allow to adjust the
trade-off between CPU cost and size gain with numerical options from -1
for fast compression and -9 for high compression ratio. zip also
accepts -0 for storing files verbatim. git archive directly support
these single-digit compression levels for ZIP output and passes them to
filters like gzip.
Zstandard additionally supports compression level options -10 to -19, or
up to -22 with --ultra. This *seems* to work with git archive in most
cases, e.g. it will produce an archive with -19 without complaining, but
since it only supports single-digit compression level options this is
the same as -1 -9 and thus -9.

the full range supported by zstd. Explicitly reject them for the ZIP
format, as otherwise deflateInit2() would just fail with a somewhat

Add some special functions that do the casting. Also, rename put->set

strmap: enable faster clearing and reusing of strmaps
When strmaps are used heavily, such as is done by my new merge-ort
algorithm, and strmaps need to be cleared but then re-used (because of
e.g. picking multiple commits to cherry-pick, or due to a recursive
merge having several different merges while recursing), free-ing and
reallocating map->table repeatedly can add up in time, especially since
it will likely be reallocated to a much smaller size but the previous
merge provides a good guide to the right size to use for the next merge.
Introduce strmap_partial_clear() to take advantage of this type of
situation; it will act similar to strmap_clear() except that
map->table's entries are zeroed instead of map->table being free'd.
Making use of this function reduced the cost of
clear_or_reinit_internal_opts() by about 20% in mert-ort, and dropped
the overall runtime of my rebase testcase by just under 2%.

strmap: add more utility functions
This adds a number of additional convienence functions I want/need:
* strmap_get_size()
* strmap_empty()
* strmap_remove()
* strmap_for_each_entry()
* strmap_get_entry()
I suspect the first four are self-explanatory.
strmap_get_entry() is similar to strmap_get() except that instead of just
returning the void* value that the string maps to, it returns the
strmap_entry that contains both the string and the void* value (or
NULL if the string isn't in the map). This is helpful because it avoids
multiple lookups, e.g. in some cases a caller would need to call:
* strmap_contains() to check that the map has an entry for the string
* strmap_get() to get the void* value
* <do some work to update the value>
* strmap_put() to update/overwrite the value
If the void* pointer returned really is a pointer, then the last step is
unnecessary, but if the void* pointer is just cast to an integer then
strmap_put() will be needed. In contrast, one can call strmap_get_entry()
and then:
* check if the string was in the map by whether the pointer is NULL
* access the value via entry->value
* directly update entry->value
meaning that we can replace two or three hash table lookups with one.

After rebasing, ORIG_HEAD is supposed to point to the old HEAD of the

object name of the old HEAD and wrote to both
.git/rebase-merge/orig-head (used by `rebase --abort` to go back to
the previous state) and to ORIG_HEAD. The buffer find_unique_abbrev()
gives back is volatile, unfortunately, and was overwritten after the
former file is written but before ORIG_FILE is written, leaving an
incorrect object name in it.
Avoid relying on the volatile buffer of find_unique_abbrev(), and
instead supply our own buffer to keep the object name.
I think that all of the users of head_hash should actually be using
opts->orig_head instead as passing a string rather than a struct
object_id around is a hang over from the scripted implementation. This
patch just fixes the immediate bug and adds a regression test based on
Caspar's reproduction example[1]. The users will be converted to use

format-patch: support --output option
We've never intended to support diff's --output option in format-patch.
And until
baa4adc66a (parse-options: disable option abbreviation with
PARSE_OPT_KEEP_UNKNOWN, 2019-01-27), it was impossible to trigger. We
first parse the format-patch options before handing the remainder off to
setup_revisions(). Before that commit, we'd accept "--output=foo" as an
abbreviation for "--output-directory=foo". But afterwards, we don't
check abbreviations, and --output gets passed to the diff code.
This results in nonsense behavior and bugs. The diff code will have
opened a filehandle at rev.diffopt.file, but we'll overwrite that with
our own handles that we open for each individual patch file. So the
--output file will always just be empty. But worse, the diff code also
sets rev.diffopt.close_file, so log_tree_commit() will close the
filehandle itself. And then the main loop in cmd_format_patch() will try
to close it again, resulting in a double-free.
The simplest solution would be to just disallow --output with
format-patch, as nobody ever intended it to work. However, we have
accidentally documented it (because format-patch includes diff-options).
And it does work with "git log", which writes the whole output to the
specified file. It's easy enough to make that work for format-patch,
too: it's really the same as --stdout, but pointed at a specific file.
We can detect the use of the --output option by the "close_file" flag
(note that we can't use rev.diffopt.file, since the diff setup will
otherwise set it to stdout). So we just need to unset that flag, but
don't have to do anything else. Our situation is otherwise exactly like
--stdout (note that we don't fclose() the file, but nor does the stdout
case; exiting the program takes care of that for us).

Incidentally, this change fixes another bug in the command line
option parser, which has allowed the -L option used together

one path given, but the former takes no pathspec, they become
mutually incompatible automatically. Because the -L option
follows renames on its own, there is no reason to give --follow

The new tests say they may fail with "-L and --follow being

32c83afc2c69 (ci: github action - add check for whitespace errors,
2020-09-22), we introduced a GitHub workflow that automatically checks
Pull Requests for whitespace problems.
However, when affected lines contain one or more double quote
characters, this workflow failed to attach the informative comment
because the Javascript snippet incorrectly interpreted these quotes
instead of using the `git log` output as-is.
Let's fix that.
While at it, let's `await` the result of the `createComment()` function.
Finally, we enclose the log in the comment with ```...``` to avoid
having the diff marker be misinterpreted as an enumeration bullet.

t5515: use `main` as the name of the main branch for testing (part 1)
As part of the effort to change the default branch name to `main`, let's
prepare t5515.
In addition to adjusting the references to the branch name itself, this
also requires two commit hashes to be adjusted (actually four, as there
is a SHA-1 _and_ a SHA-256 of both).
That trick was performed by running
sed -i -e 's/master/main/g' -e 's/Master/Main/g' \

These commit hashes have been determined manually, of course, by running
the test after adjusting only the branch names, and then copying the
hashes from the log of the failed run.
Note: this patch only touches the t5515 script so far, not the
supporting material in t/t5515/. The resulting patch would have weighed
over 100kB and therefore the Git mailing list would have dropped it. The
files in t/t5515/ will be adjusted in the next two commits. As t5515
would fail without these adjustments, we temporarily skip it via the

merge,rebase,revert: select ort or recursive by config or environment
Allow the testsuite to run where it treats requests for "recursive" or
the default merge algorithm via consulting the environment variable
GIT_TEST_MERGE_ALGORITHM which is expected to either be "recursive" (the
old traditional algorithm) or "ort" (the new algorithm).
Also, allow folks to pick the new algorithm via config setting. It
turns out builtin/merge.c already had a way to allow users to specify a
different default merge algorithm: pull.twohead. Rather odd
configuration name (especially to be in the 'pull' namespace rather than
'merge') but it's there. Add that same configuration to rebase,
cherry-pick, and revert.
This required updating the various callsites that called merge_trees()
or merge_recursive() to conditionally call the new API, so this serves
as another demonstration of what the new API looks and feels like.
There are almost certainly some callsites that have not yet been
modified to work with the new merge algorithm, but this represents the
ones that I have been testing with thus far.

hashmap: introduce a new hashmap_partial_clear()
merge-ort is a heavy user of strmaps, which are built on hashmap.[ch].
clear_or_reinit_internal_opts() in merge-ort was taking about 12% of
overall runtime in my testcase involving rebasing 35 patches of
linux.git across a big rename. clear_or_reinit_internal_opts() was
calling hashmap_free() followed by hashmap_init(), meaning that not only
was it freeing all the memory associated with each of the strmaps just
to immediately allocate a new array again, it was allocating a new array
that was likely smaller than needed (thus resulting in later need to
rehash things). The ending size of the map table on the previous commit
was likely almost perfectly sized for the next commit we wanted to pick,
and not dropping and reallocating the table immediately is a win.
Add some new API to hashmap to clear a hashmap of entries without
freeing map->table (and instead only zeroing it out like alloc_table()
would do, along with zeroing the count of items in the table and the
shrink_at field).

blame: simplify 'setup_blame_bloom_data' interface
The penultimate commit moved the initialization of 'sb.path' in
'builtin/blame.c::cmd_blame' before the call to
'blame.c::setup_blame_bloom_data'. Since 'cmd_blame' is the only caller
of 'setup_blame_bloom_data', it is now unnecessary for
'setup_blame_bloom_data' to receive 'path' as a separate argument, as
'sb.path' is already initialized.
Remove this argument from setup_blame_bloom_data's interface and use the
'path' field of the 'sb' 'struct blame_scoreboard' instead.

blame: enable funcname blaming with userdiff driver
In blame.c::cmd_blame, we send the 'path' field of the 'sb' 'struct
blame_scoreboard' as the 'path' argument to
'line-range.c::parse_range_arg', but 'sb.path' is not set yet; it's set
to the local variable 'path' a few lines later at line 1137.
This 'path' argument is only used in 'parse_range_arg' if we are blaming
a funcname, i.e. `git blame -L :<funcname> <path>`, and in that case it
is sent to 'parse_range_funcname', where it is used to determine if a
userdiff driver should be used for said <path> to match the given
funcname.
Since 'path' is yet unset, the userdiff driver is never used, so we fall
back to the default funcname regex, which is usually not appropriate for
paths that are set to use a specific userdiff driver, and thus either we
match some unrelated lines, or we die with
fatal: -L parameter '<funcname>' starting at line 1: no match
This has been the case ever since `git blame` learned to blame a
funcname in
13b8f68c1f (log -L: :pattern:file syntax to find by
funcname, 2013-03-28).
Enable funcname blaming for paths using specific userdiff drivers by
initializing 'sb.path' earlier in 'cmd_blame', when some of its other
fields are initialized, so that it is set when passed to
'parse_range_arg'.
Add a regression test in 'annotate-tests.sh', which is sourced in
t8001-annotate.sh and t8002-blame.sh, leveraging an existing file used
to test the userdiff patterns in t4018-diff-funcname.
Also, use 'sb.path' instead of 'path' when constructing the error
message at line 1114, for consistency.

and treating its failure as confirmation is fragile, as the command can

upload-pack: allow stateless client EOF just prior to haves
During stateless packfile negotiation where a depth is given, stateless
RPC clients (e.g. git-remote-curl) will send multiple upload-pack
requests with the first containing only the
wants/shallows/deepens/filters and the subsequent containing haves/done.
When upload-pack handles such requests, entering get_common_commits
without checking whether the client has hung up can result in unexpected
EOF during the negotiation loop and a die() with message "fatal: the
remote end hung up unexpectedly".
Real world effects include:
- A client speaking to git-http-backend via a server that doesn't check
the exit codes of CGIs (e.g. mod_cgi) doesn't know and doesn't care
about the fatal. It continues to process the response body as normal.
- A client speaking to a server that does check the exit code and
returns an errant HTTP status as a result will fail with the message
"error: RPC failed; HTTP 500 curl 22 The requested URL returned error:
500."
- Admins running servers that surface the failure must workaround it by
patching code that handles execution of git-http-backend to ignore exit
codes or take other heuristic approaches.
- Admins may have to deal with "hung up unexpectedly" log spam related
to the failures even in cases where the exit code isn't surfaced as an
HTTP server-side error status.
To avoid these EOF related fatals, have upload-pack gently peek for an
EOF between the sending of shallow/unshallow lines (followed by flush)
and the reading of client haves. If the client has hung up at this
point, exit normally.
