Remove the dir_init() function and replace it with a DIR_INIT
macro. In many cases in the codebase we need to initialize things with
a function for good reasons, e.g. needing to call another function on
initialization. The "dir_init()" function was not one such case, and
could trivially be replaced with a more idiomatic macro initialization
pattern.
The only place where we made use of its use of memset() was in
dir_clear() itself, which resets the contents of an an existing struct
pointer. Let's use the new "memcpy() a 'blank' struct on the stack"
idiom to do that reset.

Last minute compilation fix.

Fix a warning on AIX's xlc compiler that's been emitted since my
a1aad71601a (fsck.h: use "enum object_type" instead of "int",
2021-03-28):
"builtin/fsck.c", line 805.32: 1506-068 (W) Operation between
types "int(*)(struct object*,enum object_type,void*,struct
fsck_options*)" and "int(*)(struct object*,int,void*,struct
fsck_options*)" is not allowed.
I.e. it complains about us assigning a function with a prototype "int"
where we're expecting "enum object_type".

"ld" on Solaris fails to link some test helpers, which has been
worked around by reshuffling the inline function definitions from a
header file to a source file that is the only user of them.
* ab/pack-linkage-fix:
pack-objects: move static inline from a header to the sole consumer
|
|
Move the code that is only used in builtin/pack-objects.c out of
pack-objects.h.
This fixes an issue where Solaris's SunCC hasn't been able to compile
git since 483fa7f42d9 (t/helper/test-bitmap.c: initial commit,
2021-03-31).
The real origin of that issue is that in 898eba5e630 (pack-objects:
refer to delta objects by index instead of pointer, 2018-04-14)
utility functions only needed by builtin/pack-objects.c were added to
pack-objects.h. Since then the header has been used in a few other
places, but 483fa7f42d9 was the first time it was used by test helper.
Since Solaris is stricter about linking and the oe_get_size_slow()
function lives in builtin/pack-objects.c the build started failing
with:
Undefined first referenced
symbol in file
oe_get_size_slow t/helper/test-bitmap.o
ld: fatal: symbol referencing errors. No output written to t/helper/test-tool
On other platforms this is presumably OK because the compiler and/or
linker detects that the "static inline" functions that reference
oe_get_size_slow() aren't used.
Let's solve this by moving the relevant code from pack-objects.h to
builtin/pack-objects.c. This is almost entirely a code-only move, but
because of the early macro definitions in that file referencing some
of these inline functions we need to move the definition of "static
struct packing_data to_pack" earlier, and declare these inline
functions above the macros.

Regression fix.
* mt/init-template-userpath-fix:
init: fix bug regarding ~/ expansion in init.templateDir
|
|
We used to read the init.templateDir setting at builtin/init-db.c using
a git_config() callback that, in turn, called git_config_pathname(). To
simplify the config reading logic at this file and plug a memory leak,
this was replaced by a direct call to git_config_get_value() at
e4de4502e6 ("init: remove git_init_db_config() while fixing leaks",
2021-03-14). However, this function doesn't provide path expanding
semantics, like git_config_pathname() does, so paths with '~/' and
'~user/' are treated literally. This makes 'git init' fail to handle
init.templateDir paths using these constructs:
$ git config init.templateDir '~/templates_dir'
$ git init
'warning: templates not found in ~/templates_dir'
Replace the git_config_get_value() call by git_config_get_pathname(),
which does the '~/' and '~user/' expansions. Also add a regression test.
Note that unlike git_config_get_value(), the config cache does not own
the memory for the path returned by git_config_get_pathname(), so we
must free() it.

Another brown paper bag inconsistency fix for a new feature
introduced during this cycle.
* dl/stash-show-untracked-fixup:
stash show: use stash.showIncludeUntracked even when diff options given
|
|
The "rev-parse" command did not diagnose the lack of argument to
"--path-format" option, which was introduced in v2.31 era, which
has been corrected.
* wm/rev-parse-path-format-wo-arg:
rev-parse: fix segfault with missing --path-format argument
|
|
If options pertaining to how the diff is displayed is provided to
`git stash show`, the command will ignore the stash.showIncludeUntracked
configuration variable, defaulting to not showing any untracked files.
This is unintuitive behaviour since the format of the diff output and
whether or not to display untracked files are orthogonal.
Use stash.showIncludeUntracked even when diff options are given. Of
course, this is still overridable via the command-line options.
Update the documentation to explicitly say which configuration variables
will be overridden when a diff options are given.

Many places in the code were doing
while ((d = readdir(dir)) != NULL) {
if (is_dot_or_dotdot(d->d_name))
continue;
...process d...
}
Introduce a readdir_skip_dot_and_dotdot() helper to make that a one-liner:
while ((d = readdir_skip_dot_and_dotdot(dir)) != NULL) {
...process d...
}
This helper particularly simplifies checks for empty directories.
Also use this helper in read_cached_dir() so that our statistics are
consistent across platforms. (In other words, read_cached_dir() should
have been using is_dot_or_dotdot() and skipping such entries, but did
not and left it to treat_path() to detect and mark such entries as
path_none.)

ls-files --ignored can be used together with either --others or
--cached. After being perplexed for a bit and digging in to the code, I
assumed that ls-files -i was just broken and not printing anything and
I had a nice patch ready to submit when I finally realized that -i can be
used with --cached to find tracked ignores.
While that was a mistake on my part, and a careful reading of the
documentation could have made this more clear, I suspect this is an
error others are likely to make as well. In fact, of two uses in our
testsuite, I believe one of the two did make this error. In t1306.13,
there are NO tracked files, and all the excludes built up and used in
that test and in previous tests thus have to be about untracked files.
However, since they were looking for an empty result, the mistake went
unnoticed as their erroneous command also just happened to give an empty
answer.
-i will most the time be used with -o, which would suggest we could just
make -i imply -o in the absence of either a -o or -c, but that would be
a backward incompatible break. Instead, let's just flag -i without
either a -o or -c as an error, and update the two relevant testcases to
specify their intent.

The variable `matches` used to hold the return of a `dir_path_match()`
call that was removed in 95c11ecc73 ("Fix error-prone fill_directory()
API; make it only return matches", 2020-04-01). Now `matches` will
always hold 0, which is the value it's initialized with; and the
condition `matches != MATCHED_EXACTLY` will always evaluate to true. So
let's remove this unnecessary variable.
Interestingly, it seems that `matches != MATCHED_EXACTLY` was already
unnecessary before 95c11ecc73. That's because `remove_directories` is
always set to 1 when we have pathspecs; So, in the condition
`!remove_directories && matches != MATCHED_EXACTLY`, we would either:
- have pathspecs (or have been given `-d`) and ignore `matches` because
`remove_directories` is 1; or
- not have pathspecs (nor `-d`) and end up just checking that
`0 != MATCHED_EXACTLY`, as `matches` would never get reassigned
after its zero initialization (because there is no pathspec to match).

Allow checkout-index to use the parallel checkout framework, honoring
the checkout.workers configuration.
There are two code paths in checkout-index which call
`checkout_entry()`, and thus, can make use of parallel checkout:
`checkout_file()`, which is used to write paths explicitly given at the
command line; and `checkout_all()`, which is used to write all paths in
the index, when the `--all` option is given.
In both operation modes, checkout-index doesn't abort immediately on a
`checkout_entry()` failure. Instead, it tries to check out all remaining
paths before exiting with a non-zero exit code. To keep this behavior
when parallel checkout is being used, we must allow
`run_parallel_checkout()` to try writing the queued entries before we
exit, even if we already got an error code from a previous
`checkout_entry()` call.
However, `checkout_all()` doesn't return on errors, it calls `exit()`
with code 128. We could make it call `run_parallel_checkout()` before
exiting, but it makes the code easier to follow if we unify the exit
path for both checkout-index modes at `cmd_checkout_index()`, and let
this function take care of the interactions with the parallel checkout
API. So let's do that.
With this change, we also have to consider whether we want to keep using
128 as the error code for `git checkout-index --all`, while we use 1 for
`git checkout-index <path>` (even when the actual error is the same).
Since there is not much value in having code 128 only for `--all`, and
there is no mention about it in the docs (so it's unlikely that changing
it will break any existing script), let's make both modes exit with code
1 on `checkout_entry()` errors.

Pathspec-limited checkouts (like `git checkout *.txt`) are performed by

The transient cache entries allocated in checkout_merged() are now

Currently, the packfile negotiation step within a Git fetch cannot be
done independent of sending the packfile, even though there is at least
one application wherein this is useful. Therefore, make it possible for
this negotiation step to be done independently. A subsequent commit will
use this for one such application - push negotiation.
This feature is for protocol v2 only. (An implementation for protocol v0
would require a separate implementation in the fetch, transport, and
transport helper code.)
In the protocol, the main hindrance towards independent negotiation is
that the server can unilaterally decide to send the packfile. This is
solved by a "wait-for-done" argument: the server will then wait for the
client to say "done". In practice, the client will never say it; instead
it will cease requests once it is satisfied.
In the client, the main change lies in the transport and transport
helper code. fetch_refs_via_pack() performs everything needed - protocol
version and capability checks, and the negotiation itself.
There are 2 code paths that do not go through fetch_refs_via_pack() that
needed to be individually excluded: the bundle transport (excluded
through requiring smart_options, which the bundle transport doesn't
support) and transport helpers that do not support takeover. If or when
we support independent negotiation for protocol v0, we will need to
modify these 2 code paths to support it. But for now, report failure if
independent negotiation is requested in these cases.

A negative delta depth makes no sense, and the code is not prepared to
handle it. If passed "--depth=-1" on the command line, then this line
from break_delta_chains():
cur->depth = (total_depth--) % (depth + 1);
triggers a divide-by-zero. This is undefined behavior according to the C
standard, but on POSIX systems results in SIGFPE killing the process.
This is certainly one way to inform the use that the command was
invalid, but it's a bit friendlier to just treat it as "don't allow any
deltas", which we already do for --depth=0.

A negative window size makes no sense, and the code in find_deltas() is
not prepared to handle it. If you pass "-1", for example, we end up
generate a 0-length array of "struct unpacked", but our loop assumes it
has at least one entry in it (and we end up reading garbage memory).
We could complain to the user about this, but it's more forgiving to
just clamp it to 0, which means "do not find any deltas at all". The
0-case is already tested earlier in the script, so we'll make sure this
does the same thing.

The rewrite of git-merge from shell to C in 1c7b76be7d (Build in merge,
2008-07-07) accidentally transformed the message:
Already up-to-date. (nothing to squash)
to:
(nothing to squash)Already up-to-date.
due to reversed printf() arguments. This problem has gone unnoticed
despite being touched over the years by 7f87aff22c (Teach/Fix pull/fetch
-q/-v options, 2008-11-15) and bacec47845 (i18n: git-merge basic
messages, 2011-02-22), and tangentially by bef4830e88 (i18n: merge: mark
messages for translation, 2016-06-17) and 7560f547e6 (treewide: correct
several "up-to-date" to "up to date", 2017-08-23).
Fix it by restoring the message to its intended order. While at it, help
translators out by avoiding "sentence Lego".

Although the various "Already up to date" messages resulting from merge
attempts share identical phrasing, they use a mix of punctuation ranging
from "." to "!" and even "Yeeah!", which leads to extra work for
translators. Ease the job of translators by settling upon "." as
punctuation for all such messages.
While at it, take advantage of printf_ln() to further ease the
translation task so translators need not worry about line termination,
and fix a case of missing line termination in the (unused)
merge_ort_nonrecursive() function.
