mboxrd is a more robust output format when used with --stdout
and needs more exposure. Introducing this config knob lets
users choose the more robust format for all their --stdout
uses.
Relying on --pretty=mboxrd and including all of pretty-formats.txt
in the `git format-patch' documentation would likely be
confusing to users. Furthermore, this setting is useful across
multiple invocations. So introduce `format.mboxrd' as a boolean
configuration knob that changes the default --pretty=email format
to --pretty=mboxrd when (and only when) --stdout is in use.

A previous change introduced the transport methods to acquire a bundle
list from the 'bundle-uri' protocol v2 command, when advertised _and_
when the client has chosen to enable the feature.
Teach Git to download and unbundle the data advertised by those bundles
during 'git clone'. This takes place between the ref advertisement and
the object data download, and stateful connections will linger while
the client downloads bundles. In the future, we should consider closing
the remote connection during this process.
Also, since the --bundle-uri option exists, we do not want to mix the
advertised bundles with the user-specified bundles.

Bundle providers may want to distribute that data across multiple CDNs.
This might require a change in the base URI, all the way to the domain
name. If all bundles require an absolute URI in their 'uri' value, then
every push to a CDN would require altering the table of contents to
match the expected domain and exact location within it.
Allow a bundle list to specify a relative URI for the bundles. This URI
is based on where the client received the bundle list. For a list
provided in the 'bundle-uri' protocol v2 command, the Git remote URI is
the base URI. Otherwise, the bundle list was provided from an HTTP URI
not using the Git protocol, and that URI is the base URI. This allows
easier distribution of bundle data.

Set up all the needed client parts of the 'bundle-uri' protocol v2
command, without actually doing anything with the bundle URIs.
If the server says it supports 'bundle-uri' teach Git to issue the
'bundle-uri' command after the 'ls-refs' during 'git clone'. The
returned key=value pairs are passed to the bundle list code which is
tested using a different ingest mechanism in t5750-bundle-uri-parse.sh.
At this point, Git does nothing with that bundle list. It will not
download any of the bundles. That will come in a later change after
these protocol bits are finalized.
The no-op client is initially used only by 'git clone' to test the basic
functionality, and eventually will bootstrap the initial download of Git
objects during a fresh clone. The bundle URI client will not be
integrated into other fetches until a mechanism is created to select a
subset of bundles for download.

The previous change allowed for a Git server to advertise the
'bundle-uri' command as a capability based on the
uploadPack.advertiseBundleURIs config option. Create a set of tests that
check that this capability is advertised using 'git ls-remote'.
In order to test this functionality across three protocols (file, git,
and http), create lib-bundle-uri-protocol.sh to generalize the tests,
allowing the other test scripts to set an environment variable and
otherwise inherit the setup and tests from this script.
The tests currently only test that the 'bundle-uri' command is
advertised or not. Other actions will be tested as the Git client learns
to request the 'bundle-uri' command and parse its response.
To help with URI escaping, specifically for file paths with a space in
them, extract a 'sed' invocation from t9199-git-svn-info.sh into a
helper function for use here, too.

Add a skeleton server-side implementation of a new "bundle-uri" command
to protocol v2. This will allow conforming clients to optionally seed
their initial clones or incremental fetches from URLs containing
"*.bundle" files created with "git bundle create".
This change only performs the basic boilerplate of advertising a new
protocol v2 capability. The new 'bundle-uri' capability allows a client
to request a list of bundles. Right now, the server only returns a flush
packet, which corresponds to an empty advertisement. The bundle.* config
namespace describes which key-value pairs will be communicated across
this interface in future updates.
The critical bit right now is that the new boolean
uploadPack.adverstiseBundleURIs config value signals whether or not this
capability should be advertised at all.
An earlier version of this patch [1] used a different transfer format
than the "key=value" pairs in the current implementation. The change was
made to unify the protocol v2 command with the bundle lists provided by
independent bundle servers. Further, the standard allows for the server
to advertise a URI that contains a bundle list. This allows users
automatically discovering bundle providers that are loosely associated
with the origin server, but without the origin server knowing exactly
which bundles are currently available.

Since aef7d75e58 (builtin/bundle.c: let parse-options parse
subcommands, 2022-08-19) we've been segfaulting if no argument was
provided.
The fix is easy, as all of the "git bundle" subcommands require a
non-option argument we can check that we have arguments left after
calling parse-options().
This makes use of code added in 73c3253d75 (bundle: framework for
options before bundle file, 2019-11-10), before this change that code
has always been unreachable. In 73c3253d75 we'd never reach it as we
already checked "argc < 2" in cmd_bundle() itself.
Then when aef7d75e58 (whose segfault we're fixing here) migrated this
code to the subcommand API it removed that "argc < 2" check, but we
were still checking the wrong "argc" in parse_options_cmd_bundle(), we
need to check the "newargc". The "argc" will always be >= 1, as it
will necessarily contain at least the subcommand name
itself (e.g. "create").
As an aside, this could be safely squashed into this, but let's not do
that for this minimal segfault fix, as it's an unrelated refactoring:

Even though the cat-file command with `--batch-check` option does not
complain when `--use-mailmap` option is given, the latter option is
ignored. Compute the size of the object after replacing the idents and
report it instead.
In order to make `--batch-check` option honour the mailmap mechanism we
have to read the contents of the commit/tag object.
There were two ways to do it:
1. Make two calls to `oid_object_info_extended()`. If `--use-mailmap`
option is given, the first call will get us the type of the object
and second call will only be made if the object type is either a
commit or tag to get the contents of the object.
2. Make one call to `oid_object_info_extended()` to get the type of the
object. Then, if the object type is either of commit or tag, make a
call to `repo_read_object_file()` to read the contents of the object.
I benchmarked the following command with both the above approaches and
compared against the current implementation where `--use-mailmap`
option is ignored:
`git cat-file --use-mailmap --batch-all-objects --batch-check --buffer
--unordered`
The results can be summarized as follows:
Time (mean ± σ)
default 827.7 ms ± 104.8 ms
first approach 6.197 s ± 0.093 s
second approach 1.975 s ± 0.217 s
Since, the second approach is faster than the first one, I implemented
it in this patch.
The command git cat-file can now use the mailmap mechanism to replace
idents with canonical versions for commit and tag objects. There are
several options like `--batch`, `--batch-check` and `--batch-command`
that can be combined with `--use-mailmap`. But the documentation for
`--batch`, `--batch-check` and `--batch-command` doesn't say so. This
patch fixes that documentation.

When the -L argument to "git log" is passed the zero-width regular
expression "$" (as in "-L :$:line-range.c"), this results in an
infinite loop in find_funcname_matching_regexp().
Modify find_funcname_matching_regexp to correctly match the entire line
instead of the zero-width match at eol and update the loop condition to
prevent an infinite loop in the event of other undiscovered corner cases.
The primary change is that we pre-decrement the beginning-of-line marker
('bol') before comparing it to '\n'. In the case of '$', where we match the
'\n' at the end of the line and start the loop with bol == eol, this
ensures that bol will find the beginning of the line on which the match
occurred.

Unlike other test helper functions, 'test_oid' doesn't terminate its
output with a LF, but, alas, the reason for this, if any, is not
mentioned in 2c02b110da (t: add test functions to translate
hash-related values, 2018-09-13)).
Now, in the vast majority of cases 'test_oid' is invoked in a command
substitution that is part of a heredoc or supplies an argument to a
command or the value to a variable, and the command substitution would
chop off any trailing LFs, so in these cases the lack or presence of a
trailing LF in its output doesn't matter. However:
- There appear to be only three cases where 'test_oid' is not
invoked in a command substitution:
$ git grep '\stest_oid ' -- ':/t/*.sh'
t0000-basic.sh: test_oid zero >actual &&
t0000-basic.sh: test_oid zero >actual &&
t0000-basic.sh: test_oid zero >actual &&
These are all in test cases checking that 'test_oid' actually
works, and that the size of its output matches the size of the
corresponding hash function with conditions like
test $(wc -c <actual) -eq 40
In these cases the lack of trailing LF does actually matter,
though they could be trivially updated to account for the presence
of a trailing LF.
- There are also a few cases where the lack of trailing LF in
'test_oid's output actually hurts, because tests need to compare
its output with LF terminated file contents, forcing developers to
invoke it as 'echo $(test_oid ...)' to append the missing LF:
$ git grep 'echo "\?$(test_oid ' -- ':/t/*.sh'
t1302-repo-version.sh: echo $(test_oid version) >expect &&
t1500-rev-parse.sh: echo "$(test_oid algo)" >expect &&
t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val1)" > foo &&
t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val2)" > foo &&
t5313-pack-bounds-checks.sh: echo $(test_oid oidfff) >file &&
And there is yet another similar case in an in-flight topic at:
https://public-inbox.org/git/813e81a058227bd373cec802e443fcd677042fb4.1670862677.git.gitgitgadget@gmail.com/
Arguably we would be better off if 'test_oid' terminated its output
with a LF. So let's update 'test_oid' accordingly, update its tests
in t0000 to account for the extra character in those size tests, and
remove the now unnecessary 'echo $(...)' command substitutions around
'test_oid' invocations as well.

If you pass a bogus argument to %(refname), you may end up with a
message like this:
$ git for-each-ref --format='%(refname:foo)'
fatal: unrecognized %(refname:foo) argument: foo
which is confusing. It should just say:
fatal: unrecognized %(refname) argument: foo
which is clearer, and is consistent with most other atom parsers. Those
other parsers do not have the same problem because they pass the atom
name from a string literal in the parser function. But because the
parser for %(refname) also handles %(upstream) and %(push), it instead
uses atom->name, which includes the arguments. The oid atom parser which
handles %(tree), %(parent), etc suffers from the same problem.
It seems like the cleanest fix would be for atom->name to be _just_ the
name, since there's already a separate "args" field. But since that
field is also used for other things, we can't change it easily (e.g.,
it's how we find things in the used_atoms array, and clearly %(refname)
and %(refname:short) are not the same thing).
Instead, we'll teach our error_bad_arg() function to stop at the first
":". This is a little hacky, as we're effectively re-parsing the name,
but the format is simple enough to do this as a one-liner, and this
localizes the change to the error-reporting code.
We'll give the same treatment to err_no_arg(). None of its callers use
this atom->name trick, but it's worth future-proofing it while we're
here.

Currently, auto correction doesn't work reliably for commands which must
run in a work tree (e.g. `git status`) in Git work trees which are
created from a bare repository.
As far as I'm able to determine, this has been broken since commit
659fef199f (help: use early config when autocorrecting aliases,
2017-06-14), where the call to `git_config()` in `help_unknown_cmd()`
was replaced with a call to `read_early_config()`. From what I can tell,
the actual cause for the unexpected error is that we call
`git_default_config()` in the `git_unknown_cmd_config` callback instead
of simply returning `0` for config entries which we aren't interested
in.
Calling `git_default_config()` in this callback to `read_early_config()`
seems like a bad idea since those calls will initialize a bunch of state
in `environment.c` (among other things `is_bare_repository_cfg`) before
we've properly detected that we're running in a work tree.
All other callbacks provided to `read_early_config()` appear to only
extract their configurations while simply returning `0` for all other
config keys.
This commit changes the `git_unknown_cmd_config` callback to not call
`git_default_config()`. Instead we also simply return `0` for config
keys which we're not interested in.
Additionally the commit adds a new test case covering `help.autocorrect`
in a work tree created from a bare clone.

In b3b1a21d1a (sequencer: rewrite update-refs as user edits todo list,
2022-07-19), the 'todo_list_filter_update_refs()' step was added to handle
the removal of 'update-ref' lines from a 'rebase-todo'. Specifically, it
removes potential ref updates from the "update refs state" if a ref does not
have a corresponding 'update-ref' line.
However, because 'write_update_refs_state()' will not update the state if
the 'refs_to_oids' list was empty, removing *all* 'update-ref' lines will
result in the state remaining unchanged from how it was initialized (with
all refs' "after" OID being null). Then, when the ref update is applied, all
refs will be updated to null and consequently deleted.
To fix this, delete the 'update-refs' state file when 'refs_to_oids' is
empty. Additionally, add a tests covering "all update-ref lines removed"
cases.

grep(1) converts CRLF line endings to LF on current MinGW:
$ uname -sr
MINGW64_NT-10.0-22621 3.3.6-341.x86_64
$ printf 'a\r\n' | hexdump.exe -C
00000000 61 0d 0a |a..|
00000003
$ printf 'a\r\n' | grep . | hexdump.exe -C
00000000 61 0a |a.|
00000002
Create the intended test file by grepping the original file with LF
line endings and adding CRs explicitly.
The missing CRs went unnoticed because test_cmp on MinGW ignores line
endings since 4d715ac05c (Windows: a test_cmp that is agnostic to random
LF <> CRLF conversions, 2013-10-26). Fix this test anyway to avoid
depending on that special test_cmp behavior, especially since this is
the only test that needs it.
Piping the output of grep(1) through append_cr has the side-effect of
ignoring its return value. That means we no longer need the explicit
"|| true" to support commit messages without a body.

In Git for Windows, when passing paths from shell scripts to regular
Win32 executables, thanks to the MSYS2 runtime a somewhat magic path
conversion happens that lets the shell script think that there is a file
at `/git/Makefile` and the Win32 process it spawned thinks that the
shell script said `C:/git-sdk-64/git/Makefile` instead.
This conversion is documented in detail over here:
https://www.msys2.org/docs/filesystem-paths/#automatic-unix-windows-path-conversion
As all automatic conversions, there are gaps. For example, to avoid
mistaking command-line options like `/LOG=log.txt` (which are quite
common in the Windows world) from being mistaken for a Unix-style
absolute path, the MSYS2 runtime specifically exempts arguments
containing a `=` character from that conversion.
We are about to change `test_cmp` to use `git diff --no-index`, which
involves spawning precisely such a Win32 process.
In combination, this would cause a failure in `t0021-conversion.sh`
where we pass an absolute path containing an equal character to the
`test_cmp` function.
Seeing as the Unix tools like `cp` and `diff` that are used by Git's
test suite in the Git for Windows SDK (thanks to the MSYS2 project)
understand both Unix-style as well as Windows-style paths, we can stave
off this problem by simply switching to Windows-style paths and
side-stepping the need for any automatic path conversion.
Note: The `PATH` variable is obviously special, as it is colon-separated
in the MSYS2 Bash used by Git for Windows, and therefore _cannot_
contain absolute Windows-style paths, lest the colon after the drive
letter is mistaken for a path separator. Therefore, we need to be
careful to keep the Unix-style when modifying the `PATH` variable.

It is customary to write `A || true` to ignore a potential error exit of
command A. But when we have a sequence `A && B && C || true && D`, then
a failure of any of A, B, or C skips to D right away. This is not
intended here. Turn the command whose failure is to be ignored into a
compound command to ensure it is the only one that is allowed to fail.
