In 1119a15b5c8 (http: drop support for curl < 7.11.1, 2021-07-30)
support for curl versions older than 7.11.1 was removed, and we
currently require at least version 7.19.4, see 644de29e220 (http: drop
support for curl < 7.19.4, 2021-07-30).
In those changes this Makefile-specific check added in
0890098780f (Decide whether to build http-push in the Makefile,
2005-11-18) was missed, now that we're never going to use such an
ancient curl version we don't need to check that we have at least
7.9.8 here. I have no idea what in http-push.c broke on versions older
than that.
This does not impact "NO_CURL" setups, as this is in the "else" branch
after that check.

This script was added in f28ac70f48 (Move all dashed-form commands to
libexecdir, 2007-11-28) when commands such as "git-add" lived in the
bin directory, instead of the git exec directory.
This notice helped someone incorrectly installing version v1.6.0 and
later into a directory built for a pre-v1.6.0 git version.
We're now long past the point where anyone who'd be helped by this
warning is likely to be doing that, so let's just remove this check
and warning to simplify the Makefile.

Add $(INSTALL_STRIP), which allows passing stripping options to
$(INSTALL).
For this to work, installing executables must be split to installing
compiled binaries and scripts portions, since $(INSTALL_STRIP) is only
meaningful to the former.
Users can set this variable depending on their system. For example,
Linux users can use `-s --strip-program=strip`, while FreeBSD users can
simply set to `-s` and choose strip program with $STRIPBIN.

With the codebase firmly C99 compatible and most compilers supporting
newer versions by default, it could help bring visibility to problems.
Reverse the DEVOPTS=pedantic flag to provide a fallback for people stuck
with gcc < 5 or some other compiler that either doesn't support this flag
or has issues with it, and while at it also enable -Wpedantic which used
to be controversial[1] when Apple compilers and clang had widely divergent
version numbers.
Ideally any compiler found to have issues with these flags will be added
to an exception, and indeed, one was added to safely process windows
headers that would use non standard print identifiers, but it is expected
that more will be needed, so it could be considered a weather balloon.

Remove the USE_PARENS_AROUND_GETTEXT_N compile-time option which was
meant to catch an inadvertent mistake which is too obscure to
maintain this facility.
The backstory of how USE_PARENS_AROUND_GETTEXT_N came about is: When I
added the N_() macro in 65784830366 (i18n: add no-op _() and N_()
wrappers, 2011-02-22) it was defined as:
#define N_(msgid) (msgid)
This is non-standard C, as was noticed and fixed in 642f85faab2 (i18n:
avoid parenthesized string as array initializer, 2011-04-07).
I.e. this needed to be defined as:
#define N_(msgid) msgid
Then in e62cd35a3e8 (i18n: log: mark parseopt strings for translation,
2012-08-20) when "builtin_log_usage" was marked for translation the
string concatenation for passing to usage() added in 1c370ea4e51
(Show usage string for 'git log -h', 'git show -h' and 'git diff -h',
2009-08-06) was faithfully preserved:
- "git log [<options>] [<since>..<until>] [[--] <path>...]\n"
- " or: git show [options] <object>...",
+ N_("git log [<options>] [<since>..<until>] [[--] <path>...]\n")
+ N_(" or: git show [options] <object>..."),
This was then fixed to be the expected array of usage strings in
e66dc0cc4b1 (log.c: fix translation markings, 2015-01-06) rather than
a string with multiple "\n"-delimited usage strings, and finally in
290c8e7a3fe (gettext.h: add parentheses around N_ expansion if
supported, 2015-01-11) USE_PARENS_AROUND_GETTEXT_N was added to ensure
this mistake didn't happen again.
I think that even if this was a N_()-specific issue this
USE_PARENS_AROUND_GETTEXT_N facility wouldn't be worth it, the issue
would be too rare to worry about.
But I also think that 290c8e7a3fe which introduced
USE_PARENS_AROUND_GETTEXT_N misattributed the problem. The issue
wasn't with the N_() macro added in e62cd35a3e8, but that before the
N_() macro existed in the codebase the initial migration to
parse_options() in 1c370ea4e51 continued passsing in a "\n"-delimited
string, when the new API it was migrating to supported and expected
the passing of an array.

The rules creating the $(LIB_FILE) and $(XDIFF_LIB) archives used to
be:
$(QUIET_AR)$(RM) $@ && $(AR) $(ARFLAGS) $@ $^
until commit 7b76d6bf22 (Makefile: add and use the ".DELETE_ON_ERROR"
flag, 2021-06-29) removed the '$(RM) $@' part, claiming that "we can
rely on the "c" (create) being present in ARFLAGS", and (I presume)
assuming that it means that the named archive is created from scratch.
Unfortunately, that's not what the 'c' flag does, it merely "Suppress
the diagnostic message that is written to standard error by default
when the archive is created" [1]. Consequently, all object files that
are already present in an existing archive and are not replaced will
remain there. This leads to linker errors in back-to-back builds of
different revisions without a 'make clean' between them if source
files going into these archives are renamed in between:

Since the "tags", "TAGS" and "cscope.out" targets rely on piping into
xargs with an "echo <list> | xargs" pattern, we need to make sure
we're in an append mode.
Unlike my recent change to make use of ".DELETE_ON_ERROR" in
7b76d6bf221 (Makefile: add and use the ".DELETE_ON_ERROR" flag,
2021-06-29), we really do need the "rm $@+" at the beginning (note,
not "rm $@").
This is because the xargs command may decide to invoke the program
multiple times. We need to make sure we've got a union of its results
at the end.
For "ctags" and "etags" we used the "-a" flag for this, for cscope
that behavior is the default. Its "-u" flag disables its equivalent of
an implicit "-a" flag.
Let's also consistently use the $@ and $@+ names instead of needlessly
hardcoding or referring to more verbose names in the "tags" and "TAGS"
rules.
These targets could perhaps be improved in the future by factoring
this "echo <list> | xargs" pattern so that we make intermediate tags
files for each source file, and then assemble them into one "tags"
file at the end.
The etags manual page suggests that doing that (or perhaps just
--update) might be counter-productive, in any case, the tag building
is fast enough for me, so I'm leaving that for now.

Before we generate a "cscope.out" file, remove that file explicitly,
and not everything matching "cscope*". This doesn't change any
behavior of the Makefile in practice, but makes this rule less
confusing, and consistent with other similar rules.
The cscope target was added in a2a9150bf06 (makefile: Add a cscope
target, 2007-10-06). It has always referred to cscope* instead of to
cscope.out in .gitignore and the "clean" target, even though we only
ever generated a cscope.out file.
This was seemingly done to aid use-cases where someone invoked cscope
with the "-q" flag, which would make it create a "cscope.in.out" and
"cscope.po.out" files in addition to "cscope.out".
But us removing those files we never generated is confusing, so let's
only remove the file we need to, furthermore let's use the "-f" flag
to explicitly name the cscope.out file, even though it's the default
if not "-f" argument is supplied.
It is somewhat inconsistent to change from the glob here but not in
the "clean" rule and .gitignore, an earlier version of this change
updated those as well, but see [1][2] for why they were kept.

Portability test update.
* ab/getcwd-test:
t0001: fix broken not-quite getcwd(3) test in bed67874e2
|
|
With a54e938e5b (strbuf: support long paths w/o read rights in
strbuf_getcwd() on FreeBSD, 2017-03-26) we had t0001 break on systems
like OpenBSD and AIX whose getcwd(3) has standard (but not like glibc
et al) behavior.
This was partially fixed in bed67874e2 (t0001: skip test with
restrictive permissions if getpwd(3) respects them, 2017-08-07).
The problem with that fix is that while its analysis of the problem is
correct, it doesn't actually call getcwd(3), instead it invokes "pwd
-P". There is no guarantee that "pwd -P" is going to call getcwd(3),
as opposed to e.g. being a shell built-in.
On AIX under both bash and ksh this test breaks because "pwd -P" will
happily display the current working directory, but getcwd(3) called by
the "git init" we're testing here will fail to get it.
I checked whether clobbering the $PWD environment variable would
affect it, and it didn't. Presumably these shells keep track of their
working directory internally.
There's possible follow-up work here in teaching strbuf_getcwd() to
get the working directory with whatever method "pwd" uses on these
platforms. See [1] for a discussion of that, but let's take the easy
way out here and just skip these tests by fixing the
GETCWD_IGNORES_PERMS prerequisite to match the limitations of
strbuf_getcwd().

Originally, we refrained from adding a regression test in 7b6c6496374
(system_path(): Add prefix computation at runtime if RUNTIME_PREFIX set,
2008-08-10), and in 226c0ddd0d6 (exec_cmd: RUNTIME_PREFIX on some POSIX
systems, 2018-04-10).
The reason was that it was deemed too tricky to test.
Turns out that it is not tricky to test at all: we simply create a
pseudo-root, copy the `git` executable into the `git/` subdirectory of
that pseudo-root, then copy a script into the `libexec/git-core/`
directory and expect that to be picked up.
As long as the trash directory is in a location where binaries can be
executed, this works.

To pave the way for non-Windows platforms to define
trace2_collect_process_info(), reorganize the stub-or-definition schema
to something which doesn't directly reference Windows.
Platforms which want to collect parent process information in the
future should:
1. Add an implementation to compat/ (e.g. compat/somearch/procinfo.c)
2. Add that object to COMPAT_OBJS to config.mak.uname
(e.g. COMPAT_OBJS += compat/somearch/procinfo.o)
3. Define HAVE_PLATFORM_PROCINFO in config.mak.uname
In the Windows case, this definition lives in
compat/win32/trace2_win32_process_info.c, which is already conditionally
added to COMPAT_OBJS; so let's add HAVE_PLATFORM_PROCINFO to hint to the
build that compat/stub/procinfo.c should not be used.

This saves 8K per `struct object_directory', meaning it saves
around 800MB in my case involving 100K alternates (half or more
of those alternates are unlikely to hold loose objects).
This is implemented in two parts: a generic, allocation-free
`cbtree' and the `oidtree' wrapper on top of it. The latter
provides allocation using alloc_state as a memory pool to
improve locality and reduce free(3) overhead.
Unlike oid-array, the crit-bit tree does not require sorting.
Performance is bound by the key length, for oidtree that is
fixed at sizeof(struct object_id). There's no need to have
256 oidtrees to mitigate the O(n log n) overhead like we did
with oid-array.
Being a prefix trie, it is natively suited for expanding short
object IDs via prefix-limited iteration in
`find_short_object_filename'.
On my busy workstation, p4205 performance seems to be roughly
unchanged (+/-8%). Startup with 100K total alternates with no
loose objects seems around 10-20% faster on a hot cache.
(800MB in memory savings means more memory for the kernel FS
cache).
The generic cbtree implementation does impose some extra
overhead for oidtree in that it uses memcmp(3) on
"struct object_id" so it wastes cycles comparing 12 extra bytes
on SHA-1 repositories. I've not yet explored reducing this
overhead, but I expect there are many places in our code base
where we'd want to investigate this.

Use the GNU make ".DELETE_ON_ERROR" flag in our main Makefile, as we
already do in the Documentation/Makefile since db10fc6c09f (doc:
simplify Makefile using .DELETE_ON_ERROR, 2021-05-21).
Now if a command to make X fails X will be removed, the default
behavior of GNU make is to only do so if "make" itself is interrupted
with a signal.
E.g. if we now intentionally break one of the rules with:
- mv $@+ $@
+ mv $@+ $@ && \
+ false
We'll get output like:
$ make git
CC git.o
LINK git
make: *** [Makefile:2179: git] Error 1
make: *** Deleting file 'git'
$ file git
git: cannot open `git' (No such file or directory)
Before this change we'd leave the file in place in under this
scenario.
As in db10fc6c09f this allows us to remove patterns of removing
leftover $@ files at the start of rules, since previous failing runs
of the Makefile won't have left those littered around anymore.
I'm not as confident that we should be replacing the "mv $@+ $@"
pattern entirely, since that means that external programs or one of
our other Makefiles might race and get partial content.
I'm not changing $(REMOTE_CURL_ALIASES) since that uses a ln/ln -s/cp
dance, and would require the addition of "-f" flags if the "rm" at the
start was removed. I've also got plans to fix that ln/ln -s/cp pattern
in another series.
For $(LIB_FILE) and $(XDIFF_LIB) we can rely on the "c" (create) being
present in ARFLAGS.
I'm not changing "$(ETAGS_TARGET)", "tags" and "cscope" because
they've got a messy combination of removing "$@+" not "$@" at the
beginning, or "$@*". I'm also addressing those in another series.

This is one step towards supporting partial clone submodules.
Even after this patch, we will still lack partial clone submodules
support, primarily because a lot of Git code that accesses submodule
objects does so by adding their object stores as alternates, meaning
that any lazy fetches that would occur in the submodule would be done
based on the config of the superproject, not of the submodule. This also
prevents testing of the functionality in this patch by user-facing
commands. So for now, test this mechanism using a test helper.
Besides that, there is some code that uses the wrapper functions
like has_promisor_remote(). Those will need to be checked to see if they
could support the non-wrapper functions instead (and thus support any
repository, not just the_repository).

In some test-cases, UTF-8 locale is required. To find such locale,
we're using the first available UTF-8 locale that returned by
"locale -a".
However, the locale(1) utility is unavailable on some systems,
e.g. Linux with musl libc.
However, without "locale -a", we can't guess provided UTF-8 locale.
Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for
linux-musl in our CI system.
Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale,
since we no longer prepare the variable named "a_utf8_locale",
but set up a fallback value for GIT_TEST_UTF8_LOCALE instead.
The fallback will be LC_ALL, LANG environment variable,
or the first UTF-8 locale from output of "locale -a", in that order.

Since 07d90eadb50 (Makefile: add Perl runtime prefix support,
2018-04-10) PERL_DEFINES has been a simply-expanded variable, let's
make it recursively expanded instead.
This change doesn't matter for the correctness of the logic. Whether
we used simply-expanded or recursively expanded didn't change what we
wrote out in GIT-PERL-DEFINES, but being consistent with other rules
makes this easier to understand.

Change the logic of the i18n functions I added in 5e9637c6297 (i18n:
add infrastructure for translating Git with gettext, 2011-11-18) to
use pass-through functions when NO_GETTEXT is defined.
This speeds up the compilation time of commands that use this library
when NO_GETTEXT=Y is in effect. Loading it and POSIX.pm is around 20ms
on my machine, whereas it takes 2ms to just instantiate perl itself.

Change the logic to generate perl/build/* to regenerate those files if
GIT-PERL-DEFINES changes. This ensures that e.g. changing localedir
will result in correctly re-generated files.
I don't think that ever worked. The brokenness pre-dates my
20d2a30f8ff (Makefile: replace perl/Makefile.PL with simple make
rules, 2017-12-10).

Since 07d90eadb50 (Makefile: add Perl runtime prefix support,
2018-04-10) we have been declaring PERL_DEFINES right after assigning
to it, with the effect that the first PERL_DEFINES was ignored.
That bug didn't matter in practice since the first line had all the
same variables as the second, so we'd correctly re-generate
everything. It just made for confusing reading.
Let's remove that first assignment, and while we're at it split these
across lines to make them more maintainable.

Use multiple worker processes to distribute the queued entries and call
write_pc_item() in parallel for them. The items are distributed
uniformly in contiguous chunks. This minimizes the chances of two
workers writing to the same directory simultaneously, which could affect
performance due to lock contention in the kernel. Work stealing (or any
other format of re-distribution) is not implemented yet.
The protocol between the main process and the workers is quite simple.
They exchange binary messages packed in pkt-line format, and use
PKT-FLUSH to mark the end of input (from both sides). The main process
starts the communication by sending N pkt-lines, each corresponding to
an item that needs to be written. These packets contain all the
necessary information to load, smudge, and write the blob associated
with each item. Then it waits for the worker to send back N pkt-lines
containing the results for each item. The resulting packet must contain:
the identification number of the item that it refers to, the status of
the operation, and the lstat() data gathered after writing the file (iff
the operation was successful).
For now, checkout always uses a hardcoded value of 2 workers, only to
demonstrate that the parallel checkout framework correctly divides and
writes the queued entries. The next patch will add user configurations
and define a more reasonable default, based on tests with the said
settings.

This new interface allows us to enqueue some of the entries being
checked out to later uncompress them, apply in-process filters, and
write out the files in parallel. For now, the parallel checkout
machinery is enabled by default and there is no user configuration, but
run_parallel_checkout() just writes the queued entries in sequence
(without spawning additional workers). The next patch will actually
implement the parallelism and, later, we will make it configurable.
Note that, to avoid potential data races, not all entries are eligible
for parallel checkout. Also, paths that collide on disk (e.g.
case-sensitive paths in case-insensitive file systems), are detected by
the parallel checkout code and skipped, so that they can be safely
sequentially handled later. The collision detection works like the
following:
- If the collision was at basename (e.g. 'a/b' and 'a/B'), the framework
detects it by looking for EEXIST and EISDIR errors after an
open(O_CREAT | O_EXCL) failure.
- If the collision was at dirname (e.g. 'a/b' and 'A'), it is detected
at the has_dirs_only_path() check, which is done for the leading path
of each item in the parallel checkout queue.
Both verifications rely on the fact that, before enqueueing an entry for
parallel checkout, checkout_entry() makes sure that there is no file at
the entry's path and that its leading components are all real
directories. So, any later change in these conditions indicates that
there was a collision (either between two parallel-eligible entries or
between an eligible and an ineligible one).
After all parallel-eligible entries have been processed, the collided
(and thus, skipped) entries are sequentially fed to checkout_entry()
again. This is similar to the way the current code deals with
collisions, overwriting the previously checked out entries with the
subsequent ones. The only difference is that, since we no longer create
the files in the same order that they appear on index, we are not able
to determine which of the colliding entries will survive on disk (for
the classic code, it is always the last entry).
