e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding.,
2007-12-04) was meant to make gitweb faster by using Perl's internals
(see subsection "Messing with Perl's Internals" in Encode(3pm) manpage)
Simple benchmark confirms that (old = 00f429a, new = this version):
old new
old -- -65%
new 189% --
Unfortunately it made fallback mode of to_utf8 do not work... except
for default value 'latin1' of $fallback_encoding ('latin1' is Perl
native encoding), which is why it was not noticed for such long time.
utf8::valid(STRING) is an internal function that tests whether STRING
is in a _consistent state_ regarding UTF-8. It returns true is
well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held
as bytes (both these states are 'consistent'). For gitweb the second
option was true, as output from git commands is opened without ':utf8'
layer.
What made it work at all for STRING in 'latin1' encoding is the fact
that utf8:decode(STRING) turns on UTF-8 flag only if source string is
valid UTF-8 and contains multi-byte UTF-8 characters... and that if
string doesn't have UTF-8 flag set it is treated as in native Perl
encoding, i.e. 'latin1' / 'iso-8859-1' (unless native encoding it is
EBCDIC ;-)). It was ':utf8' layer that actually converted 'latin1'
(no UTF-8 flag == native == 'latin1) to 'utf8'.
Let's make use of the fact that utf8:decode(STRING) returns false if
STRING is invalid as UTF-8 to check whether to enable fallback mode.

The whole point of the recent update to allow "git pull $url $tagname" is
so that the integrator does not have to store the (signed) tag that is
used to convey authenticity to be recorded in the resulting merge in the
local repository's tag namespace. Asking for a merge be made with "git
pull $url tag $tagname" defeats it.
Note that the request can become ambiguous if the requestor has a branch
with the same name as the tag, but that is not a new problem limited to
pulling. I wouldn't mind if somebody wants to add disambiguation to the
find_matching_ref logic in the script as a separate patch, though.

When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.
However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.
On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.
However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref). But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.
Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.
Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).
This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

The non-streaming version of the filter counts CRLF and LF in the whole
buffer, and returns without doing anything when they match (i.e. what is
recorded in the object store already uses CRLF). This was done to help
people who added files from the DOS world before realizing they want to go
cross platform and adding .gitattributes to tell Git that they only want
CRLF in their working tree.
The streaming version of the filter does not want to read the whole thing
before starting to work, as that defeats the whole point of streaming. So
we instead check what byte follows CR whenever we see one, and add CR
before LF only when the LF does not immediately follow CR already to keep
CRLF as is.

Providing a single "-v" to "git push" currently does
nothing. Giving two flags ("git push -v -v") turns on the
first level of verbosity.
This is caused by a regression introduced in 8afd8dc (push:
support multiple levels of verbosity, 2010-02-24). Before
the series containing 8afd8dc, the verbosity handling for
fetching and pushing was completely separate. Commit bde873c
refactored the verbosity handling out of the fetch side, and
then 8afd8dc converted push to use the refactored code.
However, the fetch and push sides numbered and passed along
their verbosity levels differently. For both, a verbosity
level of "-1" meant "quiet", and "0" meant "default output".
But from there they differed.
For fetch, a verbosity level of "1" indicated to the "fetch"
program that it should make the status table slightly more
verbose, showing up-to-date entries. A verbosity level of
"2" meant that we should pass a verbose flag to the
transport; in the case of fetch-pack, this displays protocol
debugging information.
As a result, the refactored code in bde873c checks for
"verbosity >= 2", and only then passes it on to the
transport. From the transport code's perspective, a
verbosity of 0 or 1 both meant "0".
Push, on the other hand, does not show its own status table;
that is always handled by the transport layer or below
(originally send-pack itself, but these days it is done by
the transport code). So a verbosity level of 1 meant that we
should pass the verbose flag to send-pack, so that it knows
we want a verbose status table. However, once 8afd8dc
switched it to the refactored fetch code, a verbosity level
of 1 was now being ignored. Thus, you needed to
artificially bump the verbosity to 2 (via "-v -v") to have
any effect.
We can fix this by letting the transport code know about the
true verbosity level (i.e., let it distinguish level 0 or
1).
We then have to also make an adjustment to any transport
methods that assumed "verbose > 0" meant they could spew
lots of debugging information. Before, they could only get
"0" or "2", but now they will also receive "1". They need to
adjust their condition for turning on such spew from
"verbose > 0" to "verbose > 1".

2. It gave an example for --unreachable using for-each-ref

_lot_ of verification". This is hopelessly out-of-date,

Measurements by various people have shown that grepping in parallel is
not beneficial when the object store is involved. For example, with a
simple regex:
Threads | --cached case | worktree case
----------------------------------------------------------------
8 (default) | 2.88u 0.21s 0:02.94real | 0.19u 0.32s 0:00.16real
4 | 2.89u 0.29s 0:02.99real | 0.16u 0.34s 0:00.17real
2 | 2.83u 0.36s 0:02.87real | 0.18u 0.32s 0:00.26real
NO_PTHREADS | 2.16u 0.08s 0:02.25real | 0.12u 0.17s 0:00.31real
This happens because all the threads contend on read_sha1_mutex almost
all of the time. A more complex regex allows the threads to do more
work in parallel, but as Jeff King found out, the "super boost" (much
higher clock when only one core is active) feature of recent CPUs
still causes the unthreaded case to win by a large margin.
So until the pack machinery allows unthreaded access, we disable
grep's threading in all but the worktree case.

If you provide a custom rename score on the command line,
like:
git log -M50 --follow foo.c
it is completely ignored, and there is no way to --follow
with a looser rename score. Instead, let's use the same
rename score that will be used for generating diffs. This is
convenient, and mirrors what we do with the break-score.
You can see an example of it being useful in git.git:

You could have two separate rename scores, one for following
and one for diff. But almost nobody is going to want that,
and it would just be unnecessarily confusing. Besides which,
we re-use the diff results from try_to_follow_renames for
the actual diff output, which means having them as separate
scores is actively wrong. E.g., with the current code, you
get:
$ git log --oneline --diff-filter=R --name-status \
-M90 --follow git.spec.in
27dedf0 GIT 0.99.9j aka 1.0rc3
R084 git-core.spec.in git.spec.in
f85639c Rename the RPM from "git" to "git-core"
R098 git.spec.in git-core.spec.in
The first one should not be considered a rename by the -M
score we gave, but we print it anyway, since we blindly
re-use the diff information from the follow (which uses the
default score). So this could also be considered simply a
bug-fix, as with the current code "-M" is completely ignored
when using "--follow".

The "cherry-pick persists opts correctly" test in t3510

"initial" not being a merge-commit.
2. The revision range indicates that there will be a conflict that
needs to be resolved.
Although the former error is trapped, and cherry-pick die()s with the
exit status 128, the reader may be distracted by the latter. Fix this
by changing the revision range to something that wouldn't cause a
conflict. Additionally, explicitly check the exit code in

We want to run tests in a predictable, sterile environment
so we can get repeatable results. They should take as
little input as possible from the environment outside the
test script. We already sanitize environment variables, but
leave stdin untouched. This means that scripts can
accidentally be impacted by content on stdin, or whether
stdin isatty().
Furthermore, scripts reading from stdin can be annoying to
outer loops which care about their stdin offset, like:
while read sha1; do
make test
done
A test which accidentally reads stdin would soak up all of
the rest of the input intended for the outer shell loop.
Let's redirect stdin from /dev/null, which solves both
of these problems. It won't detect tests accidentally
reading from stdin, but since doing so now gives a
deterministic result, we don't need to consider that an
error.
We'll also leave file descriptor 6 as a link to the original
stdin. Tests shouldn't need to look at this, but it can be
convenient for inserting interactive commands while
debugging tests (e.g., you could insert "bash <&6 >&3 2>&4"
to run interactive commands in the environment of the test
script).
