When fetching (as opposed to cloning) from a repository with packfile
URIs enabled, an error like this may occur:
fatal: pack has bad object at offset 12: unknown object type 5
fatal: finish_http_pack_request gave result -1
fatal: fetch-pack: expected keep then TAB at start of http-fetch output
This bug was introduced in b664e9ffa1 ("fetch-pack: with packfile URIs,
use index-pack arg", 2021-02-22), when the index-pack args used when
processing the inline packfile of a fetch response and when processing
packfile URIs were unified.
This bug happens because fetch, by default, partially reads (and
consumes) the header of the inline packfile to determine if it should
store the downloaded objects as a packfile or loose objects, and thus
passes --pack_header=<...> to index-pack to inform it that some bytes
are missing. However, when it subsequently fetches the additional
packfiles linked by URIs, it reuses the same index-pack arguments, thus
wrongly passing --index-pack-arg=--pack_header=<...> when no bytes are
missing.
This does not happen when cloning because "git clone" always passes
do_keep, which instructs the fetch mechanism to always retain the
packfile, eliminating the need to read the header.
There are a few ways to fix this, including filtering out pack_header
arguments when downloading the additional packfiles, but I decided to
stick to always using index-pack throughout when packfile URIs are
present - thus, Git no longer needs to read the bytes, and no longer
needs --pack_header here.

Teach index-pack to print dangling .gitmodules links after its "keep" or
"pack" line instead of declaring an error, and teach fetch-pack to check
such lines printed.
This allows the tree side of the .gitmodules link to be in one packfile
and the blob side to be in another without failing the fsck check,
because it is now fetch-pack which checks such objects after all
packfiles have been downloaded and indexed (and not index-pack on an
individual packfile, as it is before this commit).

Unify the index-pack arguments used when processing the inline pack and
when downloading packfiles referenced by URIs. This is done by teaching
get_pack() to also store the index-pack arguments whenever at least one
packfile URI is given, and then when processing the packfile URI(s),
using the stored arguments.

This is the next step in teaching fetch-pack to pass its index-pack
arguments when processing packfiles referenced by URIs.
The "--keep" in fetch-pack.c will be replaced with a full message in a
subsequent commit.

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.

We run "git pull" against "$cask_repo"; clarify that we are
expecting not to have any of our own modifications and running "git
pull" to merely update, by passing "--ff-only" on the command line.
Also, the "brew cask install" command line triggers an error message
that says:
Error: Calling brew cask install is disabled! Use brew install
[--cask] instead.
In addition, "brew install caskroom/cask/perforce" step triggers an
error that says:
Error: caskroom/cask was moved. Tap homebrew/cask instead.
Attempt to see if blindly following the suggestion in these error
messages gets us into a better shape.

Mostly remove the comment I added 5e9637c6297 (i18n: add
infrastructure for translating Git with gettext, 2011-11-18). Since
then we had a fix in 9c0495d23e6 (gettext.c: detect the vsnprintf bug
at runtime, 2013-12-01) so we're not running with the "set back to C
locale" hack on any modern system.
So having more than 1/4 of the file taken up by a digression about a
glibc bug that mostly doesn't happen to anyone anymore is just a
needless distraction. Shorten the comment to make a brief mention of
the bug, and where to find more info by looking at the git history for
this now-removed comment.

GETTEXT_POISON a runtime option, 2018-11-08) to give anyone using that

likely to have made a change as a result, so removing this is long

The table describing the porcelain format in git-status(1) is helpful,
but it's not completely clear what the three sections mean, even to
some contributors. As a result, users are unable to find how to detect
common cases like merge conflicts programmatically.
Let's improve this situation by rephrasing to be more explicit about
what each of the sections in the table means, to tell users in plain
language which cases are occurring, and to describe what "unmerged"
means.

Commit 014ade7484 (upload-pack: send ERR packet for non-tip objects,
2019-04-13) added a test that greps the output of a failed fetch to make
sure that upload-pack sent us the ERR packet we expected. But checking
this is racy; despite the argument in that commit, the client may still
be sending a "done" line after the server exits, causing it to die() on
a failed write() and never see the ERR packet at all.
This fails quite rarely on Linux, but more often on macOS. However, it
can be triggered reliably with:
diff --git a/fetch-pack.c b/fetch-pack.c
index 876f90c759..cf40de9092 100644
--- a/fetch-pack.c
+++ b/fetch-pack.c
@@ -489,6 +489,7 @@ static int find_common(struct fetch_negotiator *negotiator,
done:
trace2_region_leave("fetch-pack", "negotiation_v0_v1", the_repository);
if (!got_ready || !no_done) {
+ sleep(1);
packet_buf_write(&req_buf, "done\n");
send_request(args, fd[1], &req_buf);
}
This is a real user-visible race that it would be nice to fix, but it's
tricky to do so: the client would have to speculatively try to read an
ERR packet after hitting a write() error. And at least for this error,
it's specific to v0 (since v2 does not enforce reachability at all).
So let's loosen the test to avoid annoying racy failures. If we
eventually do the read-after-failed-write thing, we can tighten it. And
if not, v0 will grow increasingly obsolete as servers support v2, so the
utility of this test will decrease over time anyway.
Note that we can still check stderr to make sure upload-pack bailed for
the reason we expected. It writes a similar message to stderr, and
because the server side is just another process connected by pipes,
we'll reliably see it. This would not be the case for git://, or for
ssh servers that do not relay stderr (e.g., GitHub's custom endpoint
does not).

'git for-each-repo --config=X' should return success without calling any
subcommands when the config key 'X' has no value. The current
implementation instead segfaults.
A user could run into this issue if they used 'git maintenance start' to
initialize their cron schedule using 'git for-each-repo
--config=maintenance.repo ...' but then using 'git maintenance
unregister' to remove the config option. (Note: 'git maintenance stop'
would remove the config _and_ remove the cron schedule.)
Add a simple test to ensure this works. Use 'git help --no-such-option'
as the potential subcommand to ensure that we will hit a failure if the
subcommand is ever run.

The text says "if you can certify DCO then you add a Signed-off-by
trailer". But it does not say anything about people who cannot or
do not want to certify. A natural reading may be that if you do not
certify, you must not add the trailer, but it shouldn't hurt to be
overly explicit.
