using --cleanup=verbatim to decline the default clean-up

to separate the title from the body of the message.  Be lenient
and accept a line with lone CR on it as a blank line, too.

Johannes Schindelin d98f272674 t5570: remove trailing padding
Two blocks in t5570 want to align the closing double quotes, padding
with spaces if needed. Since the maximum length of those lines is

René Scharfe cde8ea9c66 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.

Allow git archive to accept multi-digit compression levels to support
the full range supported by zstd.  Explicitly reject them for the ZIP
format, as otherwise deflateInit2() would just fail with a somewhat
cryptic "stream consistency error".

Elijah Newren 1201eb628a strmap: add a strset sub-type
Similar to adding strintmap for special-casing a string -> int mapping,
add a strset type for cases where we really are only interested in using
strmap for storing a set rather than a mapping.  In this case, we'll
always just store NULL for the value but the different struct type makes
it clearer than code comments how a variable is intended to be used.

The difference in usage also results in some differences in API: a few
things that aren't necessary or meaningful are dropped (namely, the
free_values argument to *_clear(), and the *_get() function), and
strset_add() is chosen as the API instead of strset_put().

Elijah Newren 4fa1d501f7 strmap: add functions facilitating use as a string->int map
Although strmap could be used as a string->int map, one either had to
allocate an int for every entry and then deallocate later, or one had to
do a bunch of casting between (void*) and (intptr_t).

Add some special functions that do the casting.  Also, rename put->set
for such wrapper functions since 'put' implied there may be some
deallocation needed if the string was already found in the map, which
isn't the case when we're storing an int value directly in the void*
slot instead of using the void* slot as a pointer to data.

Elijah Newren 6ccdfc2a20 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%.

Elijah Newren b70c82e6ed 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.

Phillip Wood e100bea481 rebase -i: stop overwriting ORIG_HEAD buffer
After rebasing, ORIG_HEAD is supposed to point to the old HEAD of the
rebased branch.  The code used find_unique_abbrev() to obtain 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
struct object_id and head_hash removed in the next few commits.

Jeff King dc1672dd10 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).

Jeff King 1e1693b2bb format-patch: tie file-opening logic to output_directory
In format-patch we're either outputting to stdout or to individual files
in an output directory (which may be just "./"). Our logic for whether
to open a new file for each patch is checked with "!use_stdout", but it
is equally correct to check for a non-NULL output_directory.

The distinction will matter when we add a new single-stream output in a
future patch, when only one of the three methods will want individual
files. Let's swap the logic here in preparation.

Jeff King 4c6f781f9c format-patch: refactor output selection
The --stdout and --output-directory options are mutually exclusive, but
it's hard to tell from reading the code. We have three separate
conditionals that check for use_stdout, and it's only after we've set up
the output_directory fully that we check whether the user also specified
--stdout.

Instead, let's check the exclusion explicitly first, then have a single
conditional that handles stdout versus an output directory. This is
slightly easier to follow now, and also will keep things sane when we
add another output mode in a future patch.

We'll add a few tests as well, covering the mutual exclusion and the
fact that we are not confused by a configured output directory.

Junio C Hamano 39664cb0ac log: diagnose -L used with pathspec as an error
The -L option is documented to accept no pathspec, but the
command line option parser has allowed the combination without
checking so far.  Ensure that there is no pathspec when the -L
option is in effect to fix this.

Incidentally, this change fixes another bug in the command line
option parser, which has allowed the -L option used together
with the --follow option.  Because the latter requires exactly
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
at the same time.

The new tests say they may fail with "-L and --follow being
incompatible" instead of "-L and pathspec being incompatible".
Currently the expected failure can come only from the latter, but
this is to futureproof them, in case we decide to add code to
explicititly die on -L and --follow used together.

weighed more than 100kB and therefore not made it to the Git mailing
list for review).

Similar to what we did for the `t5515` script itself in the previous
commit, this patch was generated via:

    sed -i -e 's/master/main/g' -e 's/Master/Main/g' \
        -e 's/6c9dec2b923228c9ff994c6cfe4ae16c12408dc5/ecf3b3627b498bdcb735cc4343bf165f76964e9a/g' \

	-- t/t5515/refs.*

In addition to that, we need to adjust some file _names_ in `t/t5515/`
because they encode the branch name:

    eval "$(git ls-files t/t5515/refs.\* | sed -n \
	-e 's/\(.*\)master\(.*\)/git mv & \1main\2;/p')"

Johannes Schindelin 384e08ddf3 t5515: use main as the name of the main branch for testing (part 2)
We just started preparing t5515 for the upcoming change of the default
branch name to `main`. This patch adjusts roughly half of the supporting
material in `t/t5515/` (the patch adjusting all of `t/t5515/` would have
weighed more than 100kB and therefore not made it to the Git mailing
list for review).

Similar to what we did for the `t5515` script itself in the previous

Johannes Schindelin 62e7daa0bb 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' \
        -e 's/6c9dec2b923228c9ff994c6cfe4ae16c12408dc5/ecf3b3627b498bdcb735cc4343bf165f76964e9a/g' \
	-e 's/8521c3072461fcfe8f32d67f95cc6e6b832a2db2fa29769ffc788bce85ebcd75/fff666109892bb4b1c80cd1649d2d8762a0663db8b5d46c8be98360b64fbba5f/g' \
	-e 's/754b754407bf032e9a2f9d5a9ad05ca79a6b228f/b4ab76b1a01ea602209932134a44f1e6bd610832/g' \
	-e 's/6c7abaea8a6d8ef4d89877e68462758dc6774690fbbbb0e6d7dd57415c9abde0/380ebae0113f877ce46fcdf39d5bc33e4dc0928db5c5a4d5fdc78381c4d55ae3/g' \
	-- t/t5515-*.sh

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
`PREPARE_FOR_MAIN_BRANCH` prereq.

Elijah Newren 14c4586c2d 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.
