Fix deadlocks between main Git process and subprocess spawned via
the pipe_command() API, that can kill "git add -p" that was
reimplemented in C recently.

pipe_command(): handle ENOSPC when writing to a pipe
pipe_command(): avoid xwrite() for writing to pipe
git-compat-util: make MAX_IO_SIZE define globally available
nonblock: support Windows
compat: add function to enable nonblocking pipes
|
|
We'd like to be able to make some of our pipes nonblocking so that
poll() can be used effectively, but O_NONBLOCK isn't portable. Let's
introduce a compat wrapper so this can be abstracted for each platform.
The interface is as narrow as possible to let platforms do what's
natural there (rather than having to implement fcntl() and a fake
O_NONBLOCK for example, or having to handle other types of descriptors).
The next commit will add Windows support, at which point we should be
covering all platforms in practice. But if we do find some other
platform without O_NONBLOCK, we'll return ENOSYS. Arguably we could just
trigger a build-time #error in this case, which would catch the problem
earlier. But since we're not planning to use this compat wrapper in many
code paths, a seldom-seen runtime error may be friendlier for such a
platform than blocking compilation completely. Our test suite would
still notice it.

This script is currently used by three test files: t0021-conversion.sh,
t2080-parallel-checkout-basics.sh, and
t2082-parallel-checkout-attributes.sh. To avoid the need for the PERL
dependency at these tests, let's convert the script to a C test-tool
command. The following commit will take care of actually modifying the
said tests to use the new C helper and removing the Perl script.
The Perl script flushes the log file handler after each write. As
commented in [1], this seems to be an early design decision that was
later reconsidered, but possibly ended up being left in the code by
accident:
>> +$debug->flush();
>
> Isn't $debug flushed automatically?
Maybe, but autoflush is not explicitly enabled. I will
enable it again (I disabled it because of Eric's comment
but I re-read the comment and he is only talking about
pipes).
Anyways, this behavior is not really needed for the tests and the
flush() calls make the code slightly larger, so let's avoid them
altogether in the new C version.

Create a 'git diagnose' builtin to generate a standalone zip archive of
repository diagnostics.
The "diagnose" functionality was originally implemented for Scalar in
aa5c79a331 (scalar: implement `scalar diagnose`, 2022-05-28). However, the
diagnostics gathered are not specific to Scalar-cloned repositories and
can be useful when diagnosing issues in any Git repository.

Move the core functionality of 'scalar diagnose' into a new 'diagnose.[c,h]'
library to prepare for new callers in the main Git tree generating
diagnostic archives. These callers will be introduced in subsequent patches.
While this patch appears large, it is mostly made up of moving code out of
'scalar.c' and into 'diagnose.c'. Specifically, the functions
- dir_file_stats_objects()
- dir_file_stats()
- count_files()
- loose_objs_stats()
- add_directory_to_archiver()
are all copied verbatim from 'scalar.c'. The 'create_diagnostics_archive()'
function is a mostly identical (partial) copy of 'cmd_diagnose()', with the
primary changes being that 'zip_path' is an input and "Enlistment root" is
corrected to "Repository root" in the archiver log.

Before implementing a way to fetch bundles into a repository, create the
basic logic. Assume that the URI is actually a file path. Future logic
will make this more careful to other protocols.
For now, we also only succeed if the content at the URI is a bundle
file, not a bundle list. Bundle lists will be implemented in a future
change.
Note that the discovery of a temporary filename is slightly racy because
the odb_mkstemp() relies on the temporary file not existing. With the
current implementation being limited to file copies, we could replace
the copy_file() with copy_fd(). The tricky part comes in future changes
that send the filename to 'git remote-https' and its 'get' capability.
At that point, we need the file descriptor closed _and_ the file
unlinked. If we were to keep the file descriptor open for the sake of
normal file copies, then we would pollute the rest of the code for
little benefit. This is especially the case because we expect that most
bundle URI use will be based on HTTPS instead of file copies.

Create a new "Repository, command and file interfaces" section in the
main "git help git" manual page. Move things that belong under this
new criteria from the generic "Guides" section.
The "Guides" section was added in f442f28a81b (git.txt: add list of
guides, 2020-08-05). It makes sense to have e.g. "giteveryday(7)" and
"gitfaq(7)" listed under "Guides".
But placing e.g. "gitignore(5)" in it is stretching the meaning of
what a "guide" is, ideally that section should list things similar to
"giteveryday(7)" and "gitcore-tutorial(7)".
An alternate name that was considered for this new section was "User
formats", for consistency with the nomenclature used for man section 5
in general. My man(1) lists it as "File formats and conventions,
e.g. /etc/passwd".
So calling this "git help --formats" or "git help --user-formats"
would make sense for e.g. gitignore(5), but would be stretching it
somewhat for githooks(5), and would seem really suspect for the likes
of gitcli(7).
Let's instead pick a name that's closer to the generic term "User
interface", which is really what this documentation discusses: General
user-interface documentation that doesn't obviously belong elsewhere.

For SHA-256, we currently have support for OpenSSL and libgcrypt because
these two libraries contain optimized implementations that can take
advantage of native processor instructions. However, OpenSSL is not
suitable for linking against for Linux distros due to licensing
incompatibilities with the GPLv2, and libgcrypt has been less favored by
cryptographers due to some security-related implementation issues,
which, while not affecting our use of hash algorithms, has affected its
reputation.
Let's add another option that's compatible with the GPLv2, which is
Nettle. This is an option which is generally better than libgcrypt
because on many distros GnuTLS (which uses Nettle) is used for HTTPS and
therefore as a practical matter it will be available on most systems.
As a result, prefer it over libgcrypt and our built-in implementation.
Nettle also has recently gained support for Intel's SHA-NI instructions,
which compare very favorably to other implementations, as well as
assembly implementations for when SHA-NI is not available.
A git gc on git.git sees a 12% performance improvement with Nettle over
our block SHA-256 implementation due to general assembly improvements.
With SHA-NI, the performance of raw SHA-256 on a 2 GiB file goes from
7.296 seconds with block SHA-256 to 1.523 seconds with Nettle.

Add a "coccicheck-test" target to test our *.cocci rules, and as a
demonstration add tests for the rules added in 39ea59a2570 (remove
unnecessary NULL check before free(3), 2016-10-08) and
1b83d1251ed (coccinelle: add a rule to make "expression" code use
FREE_AND_NULL(), 2017-06-15).
I considered making use of the "spatch --test" option, and the choice
of a "tests" over a "t" directory is to make these tests compatible
with such a future change.
Unfortunately "spatch --test" doesn't return meaningful exit codes,
AFAICT you need to "grep" its output to see if the *.res is what you
expect. There's "--test-okfailed", but I didn't find a way to sensibly
integrate those (it relies on some in-between status files, but
doesn't help with the status codes).
Instead let's use a "--sp-file" pattern similar to the main
"coccicheck" rule, with the difference that we use and compare the
two *.res files with cmp(1).
The --very-quiet and --no-show-diff options ensure that we don't need
to pipe stdout and stderr somewhere. Unlike the "%.cocci.patch" rule
we're not using the diff.
The "cmp || git diff" is optimistically giving us better output on
failure, but even if we only have POSIX cmp and no system git
installed we'll still fail with the "cmp", just with an error message
that isn't as friendly. The "2>/dev/null" is in case we don't have a
"git" installed.

The "--patch ." part of SPATCH_FLAGS added in f57d11728d1 (coccinelle:
put sane filenames into output patches, 2018-07-23) should have been
added unconditionally to the "spatch" invocation instead, using it
isn't optional.
Let's also move the other mandatory flag to come after
$(SPATCH_FLAGS), to ensure that our "--sp-file" overrides any provided
in the environment, both --sp-file <arg> and --patch <arg> are
last-option-wins as far as spatch(1) option parsing is concerned.
The environment variable override was initially added in
a9a884aea57 (coccicheck: use --all-includes by default,
2016-09-30). In practice there's probably nobody that's using
SPATCH_FLAGS to try to intentionally break our invocations, but since
we're changing this let's make it clear what (if anything) we expect
to be overridden by user-supplied flags.

From looking at the {Free,Net,Dragonfly}BSD packages for git[1]
they've been monkeypatching "gitweb" out of the Makefile, let's be
nicer and provide a NO_GITWEB=Y for their use.
For the "all" target this allows for optionally restoring what's been
the status quo before the preceding commit, but now we'll also behave
correctly on the subsequent "make install".
As before our installation of gitweb can be suppressed with
NO_PERL. For backwards compatibility the NO_PERL=Y flag by itself
still doesn't change whether or not we build gitweb, unlike the new
NO_GITWEB=Y flag.

Our Makefile's default target used to build 'gitweb', though
indirectly: the 'all' target depended on 'git-instaweb', which in turn
depended on 'gitweb'. Then e25c7cc146 (Makefile: drop dependency
between git-instaweb and gitweb, 2015-05-29) removed the latter
dependency, and for good reasons (quoting its commit message):
"1. git-instaweb has no build-time dependency on gitweb; it
is a run-time dependency
2. gitweb is a directory that we want to recursively make
in. As a result, its recipe is marked .PHONY, which
causes "make" to rebuild git-instaweb every time it is
run."
Since then a simple 'make' doesn't build 'gitweb'.
Luckily, installing 'gitweb' is not broken: although 'make install'
doesn't depend on the 'gitweb' target, it has a dependency on the
'install-gitweb' target, which does generate all the necessary files
for 'gitweb' and installs them. However, if someone runs 'make &&
sudo make install', then those files in the 'gitweb' directory will be
generated and owned by root, which is not nice.
List 'gitweb' as a direct dependency of the default target, so a plain
'make' will build it.

Include the gitweb/Makefile in the top-level Makefile rather than
calling it as a sub-Makefile. As noted in the thread starting at at
[1] (in particular [2]) we'll pay a high cost on NOOP runs of "make"
just to figure out that we have nothing to do for "make gitweb".
The "gitweb" script also isn't maintained out-of-tree, unlike
"gitk-git" or "git-gui", which both have their own "Makefile". Other
parts of it are already integrated into our main Makefiles, e.g. the

Create another thread to watch over the daemon process and
automatically shut it down if necessary.
This commit creates the basic framework for a "health" thread
to monitor the daemon and/or the file system. Later commits
will add platform-specific code to do the actual work.
The "health" thread is intended to monitor conditions that
would be difficult to track inside the IPC thread pool and/or
the file system listener threads. For example, when there are
file system events outside of the watched worktree root or if
we want to have an idle-timeout auto-shutdown feature.
This commit creates the health thread itself, defines the thread-proc
and sets up the thread's event loop. It integrates this new thread
into the existing IPC and Listener thread models.
This commit defines the API to the platform-specific code where all of
the monitoring will actually happen.
The platform-specific code for MacOS is just stubs. Meaning that the
health thread will immediately exit on MacOS, but that is OK and
expected. Future work can define MacOS-specific monitoring.
The platform-specific code for Windows sets up enough of the
WaitForMultipleObjects() machinery to watch for system and/or custom
events. Currently, the set of wait handles only includes our custom
shutdown event (sent from our other theads). Later commits in this
series will extend the set of wait handles to monitor other
conditions.

The core translation is the minimum set of work that must be done for a
new language translation.
There are over 5000 messages in the template message file "po/git.pot"
that need to be translated. It is not a piece of cake for such a huge

translation" that a new l10n contributor must complete before sending
pull request to the l10n coordinator.
By pulling in some parts of the git-po-helper[^1] logic, we add a new
rule to create this core translation message "po/git-core.pot":
make po/git-core.pot
To help new l10n contributors to initialized their "po/XX.pot" from
"po/git-core.pot", we also add new rules "po-init":

Remove the "po/git.pot" file from being tracked, which started with
dce37b66fb0 (l10n: initial git.pot for 1.7.10 upcoming release,
2012-02-13).
The reason the po/git.pot started being checked in was because the
po/*.po files were changed a schema where we'd generate them from a
known-good snapshot of po/git.pot, instead of each translator running
"make pot" themselves.
This makes sense, but we don't need to carry this file in-tree just to
achieve that aim, and doing so has resulted in a significant amount of
"diff churn" since this method of doing it was introduced:
$ git log -p --oneline -- po/git.pot|wc -l

We can instead let l10n contributors to generate "po/git.pot" in runtime
to update their own "po/XX.po", and the l10n coordinator can check
pull requests using CI pipeline.
This reverts to the schema introduced initially in cd5513a7168 (i18n:
Makefile: "pot" target to extract messages marked for translation,
2011-02-22).
The actual "git rm" of po/git.pot was in preceding commit to make this
change easier to review, and to preempt the mailing list from blocking
it due to it being too large.

We get source files saved in "$(FOUND_SOURCE_FILES)" by running the
command "git ls-files" or the command "find". We tried to have the
both commands return the same list of files, but apparently the "find"
command will return more files, such as the generated headers. We can
filter out these generated headers to get closer results.
In addition to this, "$(FOUND_SOURCE_FILES)" may contain duplicate
files. E.g. "git-ls-files" may have duplicate entries for the same file
in different staging areas if there are unresolved conflicts in the
working tree. For this case, we can reduce duplicate entries by passing
the option "--deduplicate" to git-ls-files.
Junio reported that when running "make" in a working tree with
unresolved conflicts, "make" may report warnings like below:
Makefile:xxxx: target '.build/pot/po/FOO.c.po' given more than once
in the same rule
The duplicate targets are introduced by the following pattern rule we
added in the preceding commit for incremental build of "po/git.pot".
$(LOCALIZED_C_GEN_PO): .build/pot/po/%.po: %
Although we have resolved this issue by sorting to create a unique
$(LOCALIZED_C), other targets may benefit from this. Such as: tags,
cscope.out, etc.

In the preceding commit we moved away from using xgettext(1) to both
generate the po/git.pot, and to merge the incrementally generated
po/git.pot+ file as we sourced translations from C, shell and Perl.
Doing it this way, which dates back to my initial
implementation[1][2][3] was conflating two things: With xgettext(1)
the --from-code both controls what encoding is specified in the
po/git.pot's header, and what encoding we allow in source messages.
We don't ever want to allow non-ASCII in *source messages*, and doing
so has hid e.g. a buggy message introduced in
a6226fd772b (submodule--helper: convert the bulk of cmd_add() to C,
2021-08-10) from us, we'd warn about it before, but only when running
"make pot", but the operation would still succeed. Now we'll error out
on it when running "make pot".
Since the preceding Makefile changes made this easy: let's add a "make
check-pot" target with the same prerequisites as the "po/git.pot"
target, but without changing the file "po/git.pot". Running it as part
of the "static-analysis" CI target will ensure that we catch any such
issues in the future. E.g.:
$ make check-pot
XGETTEXT .build/pot/po/builtin/submodule--helper.c.po
xgettext: Non-ASCII string at builtin/submodule--helper.c:3381.
Please specify the source encoding through --from-code.

Before commit fc0fd5b23b (Makefile: help gettext tools to cope with our
custom PRItime format, 2017-07-20), we'd consider source files as-is
with gettext, but because we need to understand PRItime in the same way
that gettext itself understands PRIuMAX, we'd first check if we had a
clean checkout, then munge all of the processed files in-place with
"sed", generate "po/git.pot", and then finally "reset --hard" to undo
our changes.
By generating "pot" snippets in ".build/pot/po" for each source file
and rewriting certain source files with PRItime macros to temporary
files in ".build/pot/po", we can avoid running "make pot" by altering
files in place and doing a "reset --hard" afterwards.
This speed of "make pot" is slower than before on an initial run,
because we run "xgettext" many times (once per source file), but it
can be boosted by parallelization. It is *much* faster for incremental
runs, and will allow us to implement related targets in subsequent
commits.
When the "pot" target was originally added in cd5513a7168 (i18n:
Makefile: "pot" target to extract messages marked for translation,
2011-02-22) it behaved like a "normal" target. I.e. we'd skip the
re-generation of the po/git.pot if nothing had to be done.
Then after po/git.pot was checked in in dce37b66fb0 (l10n: initial
git.pot for 1.7.10 upcoming release, 2012-02-13) the target was broken
until 1f31963e921 (i18n: treat "make pot" as an explicitly-invoked
target, 2014-08-22) when it was made to depend on "FORCE". I.e. the
Makefile's dependency resolution inherently can't handle incremental
building when the target file may be updated by git (or something else
external to "make"). But this case no longer applies, so FORCE is no
longer needed.
That out of the way, the main logic change here is getting rid of the
"reset --hard":
We'll generate intermediate ".build/pot/po/%.po" files from "%", which
is handy to see at a glance what strings (if any) in a given file are
marked for translation:
$ make .build/pot/po/pretty.c.po
[...]
$ cat .build/pot/po/pretty.c.po
#: pretty.c:1051
msgid "unable to parse --pretty format"
msgstr ""
$
For these C source files which contain the PRItime macros, we will
create temporary munged "*.c" files in a tree in ".build/pot/po"
corresponding to our source tree, and have "xgettext" consider those.
The rule needs to be careful to "(cd .build/pot/po && ...)", because
otherwise the comments in the po/git.pot file wouldn't refer to the
correct source locations (they'd be prefixed with ".build/pot/po").
These temporary munged "*.c” files will be removed immediately after
the corresponding po files are generated, because some development tools
cannot ignore the duplicate source files in the ".build" directory
according to the ".gitignore" file, and that may cause trouble.
The output of the generated po/git.pot file is changed in one minor
way: Because we're using msgcat(1) instead of xgettext(1) to
concatenate the output we'll now disambiguate where "TRANSLATORS"
comments come from, in cases where a message is the same in N files,
and either only one has a "TRANSLATORS" comment, or they're
different. E.g. for the "Your edited hunk[...]" message we'll now
apply this change (comment content elided):
+#. #-#-#-#-# add-patch.c.po #-#-#-#-#
#. TRANSLATORS: do not translate [y/n]
[...]
+#. #-#-#-#-# git-add--interactive.perl.po #-#-#-#-#
#. TRANSLATORS: do not translate [y/n]
[...]
#: add-patch.c:1253 git-add--interactive.perl:1244
msgid ""
"Your edited hunk does not apply. Edit again (saying \"no\" discards!) [y/n]? "
msgstr ""
There are six such changes, and they all make the context more
understandable, as msgcat(1) is better at handling these edge cases
than xgettext(1)'s previously used "--join-existing" flag.
But filenames in the above disambiguation lines of extracted-comments
have an extra ".po" extension compared to the filenames at the file
locations. While we could rename the intermediate ".build/pot/po/%.po"
files without the ".po" extension to use more intuitive filenames in
the disambiguation lines of extracted-comments, but that will confuse
developer tools with lots of invalid C or other source files in
".build/pot/po" directory.
The addition of "--omit-header" option for xgettext makes the "pot"
snippets in ".build/pot/po/*.po" smaller. But as we'll see in a
subsequent commit this header behavior has been hiding an
encoding-related bug from us, so let's carry it forward instead of
re-generating it with xgettext(1).
The "po/git.pot" file should have a header entry, because a proper
header entry will increase the speed of creating a new po file using
msginit and set a proper "POT-Creation-Date:" field in the header
entry of a "po/XX.po" file. We use xgettext to generate a separate
header file at ".build/pot/git.header" from "/dev/null", and use this
header to assemble "po/git.pot".

Different users may generate a different message template file
"po/git.pot". This is because the POT file is generated from
"$(LOCALIZED_C)", which is supposed to list all the sources that we
extract the strings to be translated from. But "$(LOCALIZED_C)"
includes "$(C_OBJ)", which only lists the source files used in the
current build for a specific platform and specific compiler
conditions.
Instead of using "$(C_OBJ)", we use "$(FOUND_C_SOURCES)", which lists
all source files we keep track of (or ship in a tarball extract), to
form a stable "LOCALIZED_C". We also add "$(SCALAR_SOURCES)", which
is part of "$(C_OBJ)" but not included in "$(FOUND_C_SOURCES)".
With this update, the newly generated "po/git.pot" will have 30 new
entries coming from the following C source files:
* compat/fsmonitor/fsm-listen-win32.c
* compat/mingw.c
* compat/regex/regcomp.c
* compat/simple-ipc/ipc-win32.c

We will feed xgettext with more C source files and in different order
in subsequent commit. To generate a stable "po/git.pot" regardless of
the number and order of input source files, we sort the c, perl, and
shell source files in groups before feeding them to xgettext.
Ævar suggested that we should not pass the option "--sort-by-file" to
xgettext to sort the translatable strings, as it will mix the three
groups of source files (c, perl and shell) in the file "po/git.pot",
and change the order of translatable strings in the same line of a file.
With this update, the newly generated "po/git.pot" will have the same
entries while in a different order.
With the help of a custom diff driver as shown below,
git config --global diff.gettext-fmt.textconv \
"msgcat --no-location --sort-by-file"
and appending a new entry "*.pot diff=gettext-fmt" to git attributes,
we can see that there are no substantial changes in "po/git.pot".
We won't checkin the newly generated "po/git.pot", because we will
remove it from tree in a later commit.

Directly invoking make coverage-report as a target results in an error because
its prerequisites are missing,
This patch adds the compile-test prerequisite, which is run only once each time
the compile-report target is invoked. In practice, the developer may decide to
review the coverage-report results without necessarily rerunning for this
coverage-test, if it has already been run.

As the address sanitizer checks for a superset of the issues detected
by setting MALLOC_CHECK_ (which tries to detect things like double
frees and off-by-one errors) there is no need to set the latter when
compiling with -fsanitize=address.
This fixes a regression introduced by 131b94a10a ("test-lib.sh: Use
GLIBC_TUNABLES instead of MALLOC_CHECK_ on glibc >= 2.34", 2022-03-04)
which causes all the tests to fail with the message
ASan runtime does not come first in initial library list;
you should either link runtime to your application or
manually preload it with LD_PRELOAD.
when git is compiled with SANITIZE=address on systems with glibc >=
2.34. I have tested SANITIZE=leak and SANITIZE=undefined and they do
not suffer from this regression so the fix in this patch should be
sufficient.

Build fix.

git-compat-util: really support openssl as a source of entropy
|
|
05cd988dce5 (wrapper: add a helper to generate numbers from a CSPRNG,
2022-01-17), configure openssl as the source for entropy in NON-STOP
but doesn't add the needed header or link options.
Since the only system that is configured to use openssl as a source
of entropy is NON-STOP, add the header unconditionally, and -lcrypto
to the list of external libraries.
An additional change is required to make sure a NO_OPENSSL=1 build
will be able to work as well (tested on Linux with a modified value
of CSPRNG_METHOD = openssl), and the more complex logic that allows
for compatibility with APPLE_COMMON_CRYPTO or allowing for simpler
ways to link (without libssl) has been punted for now.
