Currently, when fetching, packfiles referenced by URIs are run through
index-pack without any arguments other than --stdin and --keep, no
matter what arguments are used for the packfile that is inline in the
fetch response. As a preparation for ensuring that all packs (whether
inline or not) use the same index-pack arguments, teach the http
subsystem to allow custom index-pack arguments.
http-fetch has been updated to use the new API. For now, it passes
--keep alone instead of --keep with a process ID, but this is only
temporary because http-fetch itself will be taught to accept index-pack
parameters (instead of using a hardcoded constant) in a subsequent
commit.

In dd4b732df7 ("upload-pack: send part of packfile response as uri",
2020-06-10), the git http-fetch code learned how to take ac --packfile
option. This option takes an argument, which is the name of a packfile
hash, and parses it using parse_oid_hex. It does so before calling
setup_git_directory.
However, in a SHA-256 repository this fails to work, since we have not
set the hash algorithm in use and parse_oid_hex fails as a consequence.
To ensure that we can parse packfile hashes of the right length, let's
set up the git directory before we start parsing arguments.
Since we still want to allow the invocation of -h to print the help when
we're not in a repository, gracefully handle us being outside of one and
produce an error after argument parsing has finished.

This is a follow-up to a6c786fce8 (Mark http-fetch without -a as
deprecated, 2011-08-23). For more than six years, we have been warning
when `-a` is not provided, and the documentation has been saying that
`-a` will become the default.
It is a bit unclear what "default" means here. There is no such thing as
`http-fetch --no-a`. But according to my searches, no-one has been
asking on the mailing list how they should silence the warning and
prepare for overriding the flipped default. So let's assume that
everybody is happy with `-a`. They should be, since not using it may
break the repo in such a way that Git itself is unable to fix it.
Always behave as if `-a` was given. Since `-a` implies `-c` (get commit
objects) and `-t` (get trees), all three options are now unnecessary.
Document all of these as historical artefacts that have no effect.
Leave no-op code for handling these options in http-fetch.c. The
options-handling is currently rather loose. If someone tightens it, we
will not want these ignored options to accidentally turn into hard
errors.
Since `-a` was the only safe and sane usage and we have been pushing
people towards it for a long time, refrain from warning when it is used
"unnecessarily" now. Similarly, do not add anything scary-looking to the
man-page about how it will be removed in the future. We can always do so
later. (It is not like we are in desperate need of freeing up
one-letter arguments.)

Every program which links against libgit.a must call this
function, or risk hitting an assert() in system_path() that
checks whether we have configured argv0_path (though only
when RUNTIME_PREFIX is defined, so essentially only on
Windows).
Looking at the diff, you can see that putting it into the
common main() saves us having to do it individually in each
of the external commands. But what you can't see are the
cases where we _should_ have been doing so, but weren't
(e.g., git-credential-store, and all of the t/helper test
programs).
This has been an accident-waiting-to-happen for a long time,
but wasn't triggered until recently because it involves one
of those programs actually calling system_path(). That
happened with git-credential-store in v2.8.0 with ae5f677
(lazily load core.sharedrepository, 2016-03-11). The
program:
- takes a lock file, which...
- opens a tempfile, which...
- calls adjust_shared_perm to fix permissions, which...
- lazy-loads the config (as of ae5f677), which...
- calls system_path() to find the location of
/etc/gitconfig
On systems with RUNTIME_PREFIX, this means credential-store
reliably hits that assert() and cannot be used.
We never noticed in the test suite, because we set
GIT_CONFIG_NOSYSTEM there, which skips the system_path()
lookup entirely. But if we were to tweak git_config() to
find /etc/gitconfig even when we aren't going to open it,
then the test suite shows multiple failures (for
credential-store, and for some other test helpers). I didn't
include that tweak here because it's way too specific to
this particular call to be worth carrying around what is
essentially dead code.
The implementation is fairly straightforward, with one
exception: there is exactly one caller (git.c) that actually
cares about the result of the function, and not the
side-effect of setting up argv0_path. We can accommodate
that by simply replacing the value of argv[0] in the array
we hand down to cmd_main().

There are certain startup tasks that we expect every git
process to do. In some cases this is just to improve the
quality of the program (e.g., setting up gettext()). In
others it is a requirement for using certain functions in
libgit.a (e.g., system_path() expects that you have called
git_extract_argv0_path()).
Most commands are builtins and are covered by the git.c
version of main(). However, there are still a few external
commands that use their own main(). Each of these has to
remember to include the correct startup sequence, and we are
not always consistent.
Rather than just fix the inconsistencies, let's make this
harder to get wrong by providing a common main() that can
run this standard startup.
We basically have two options to do this:
- the compat/mingw.h file already does something like this by
adding a #define that replaces the definition of main with a
wrapper that calls mingw_startup().
The upside is that the code in each program doesn't need
to be changed at all; it's rewritten on the fly by the
preprocessor.
The downside is that it may make debugging of the startup
sequence a bit more confusing, as the preprocessor is
quietly inserting new code.
- the builtin functions are all of the form cmd_foo(),
and git.c's main() calls them.
This is much more explicit, which may make things more
obvious to somebody reading the code. It's also more
flexible (because of course we have to figure out _which_
cmd_foo() to call).
The downside is that each of the builtins must define
cmd_foo(), instead of just main().
This patch chooses the latter option, preferring the more
explicit approach, even though it is more invasive. We
introduce a new file common-main.c, with the "real" main. It
expects to call cmd_main() from whatever other objects it is
linked against.
We link common-main.o against anything that links against
libgit.a, since we know that such programs will need to do
this setup. Note that common-main.o can't actually go inside
libgit.a, as the linker would not pick up its main()
function automatically (it has no callers).
The rest of the patch is just adjusting all of the various
external programs (mostly in t/helper) to use cmd_main().
I've provided a global declaration for cmd_main(), which
means that all of the programs also need to match its
signature. In particular, many functions need to switch to
"const char **" instead of "char **" for argv. This effect
ripples out to a few other variables and functions, as well.
This makes the patch even more invasive, but the end result
is much better. We should be treating argv strings as const
anyway, and now all programs conform to the same signature
(which also matches the way builtins are defined).

Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.
However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).
Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

- incomplete; http-fetch doesn't have a remote, so passes

- cumbersome; http-push has a similar problem to
http-fetch, but actually builds a fake remote just to

And even for an isolated group where everybody knows that

prepared for ls-remote and git-fetch script, which means you

http-fetch.c: drop remote_ls()
While doing remote_ls() over DAV potentially allows the server
side not to keep objects/info/pack up-to-date, misconfigured or
buggy servers can silently ignore or not to respond to DAV
requests and makes the client hang.
The server side (unfortunately) needs to run git-update-server-info
even if remote_ls() removes the need to keep objects/info/pack file
up-to-date, because the caller of git-http-fetch (git-fetch) and other
clients that interact with the repository (e.g. git-ls-remote) need to
read from info/refs file (there is no code to make that unnecessary by
using DAV yet).
Perhaps the right solution in the longer-term is to make info/refs
also unnecessary by using DAV, and we would want to resurrect the
code this patch removes when we do so, but let's drop remote_ls()
implementation for now. It is causing problems without really

[jc: I needed to hand merge the changes to the updated codebase,
so the result needs to be checked.]

As Fredrik points out the current interface of has_extension() is
potentially confusing. Its parameters include both a nul-terminated
string and a length-limited string.
This patch drops the length argument, requiring two nul-terminated
strings; all callsites are updated. I checked that all of them indeed
provide nul-terminated strings. Filenames need to be nul-terminated
anyway if they are to be passed to open() etc. The performance penalty
of the additional strlen() is negligible compared to the system calls
which inevitably surround has_extension() calls.
Additionally, change has_extension() to use size_t inside instead of
int, as that is the exact type strlen() returns and memcmp() expects.

The little helper has_extension() documents through its name what we are
trying to do and makes sure we don't forget the underrun check.
