Replace the use of the "open" pragma with a three-arg open in the
places that actually care about UTF-8, while leaving those that
don't (the config parsing).
Unlike the previous "encoding" pragma change this isn't needed for
compatibility with anything. I just think it's easier to read code
that has localized effects than code that changes global settings.

The use of the encoding pragma has been a hard error since Perl
5.18 (released in 2013).
What this script really wanted to do was to decode @ARGV and write out
some files with the UTF-8 PerlIO layer. Let's just do that explicitly
instead.
This explicitly does not retain the previous UTF-8 semantics of the
script. The "encoding" pragma had all sorts of global effects (program
text being UTF-8, stdin/stdout etc.). But the only thing that was
required was decoding @ARGV and writing out UTF-8 data, which is
currently facilitated with the "open" pragma.

Change the dispatch table code in test-gitmw.pl to use a hash where

Change code that used an ad-hoc "diff -b" invocation to use our
test_cmp helper instead. I'm also changing the order of arguments to
be the standard "test_cmp <expected> <actual>".
Using test_cmp has different semantics since the "-b" option to diff
causes it to ignore whitespace, but in these cases the use of "-b" was
just meaningless boilerplate. The desired semantics here are to
compare "git log" lines with know-good data, so we don't want to
ignore whitespace.

In more recent versions of MediaWiki this is a requirement, e.g. the
current stable version of 1.32.2.
The web installer now refuses our old 9 character password, the
command-line one (will be used in a subsequent change) will accept it,
but trying to use it in the web UI will emit an error asking the user
to reset the password. Let's use a password that'll just work and
allow us to log in as the admin user.

Change the hardcoded version 5 PHP versions to the version-agnostic
packages. Currently Debian stable's version is 7.3, and there's a
php7.3, php7.3-cli etc. package available (but no php5-*).
The corresponding version-less package is a dependency package which
depends on whatever the current stable version is. By not hardcoding
the version these instructions won't be out of date when the next
Debian/Ubuntu release happens.

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

In preparation for a future patch adding a boolean parameter to
repo_interpret_branch_name(), which might be easily confused with an
existing unsigned int parameter, refactor repo_interpret_branch_name()
to take an option struct instead of the unsigned int parameter.
The static function interpret_branch_mark() is also updated to take the
option struct in preparation for that future patch, since it will also
make use of the to-be-introduced boolean parameter.

887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update",
2020-08-18) introduced the ability to disable writing to FETCH_HEAD
during fetch, but did not suppress the "<source> -> FETCH_HEAD" message
when this ability is used. This message is misleading in this case,
because FETCH_HEAD is not written. Also, because "fetch" is used to
lazy-fetch missing objects in a partial clone, this significantly
clutters up the output in that case since the objects to be fetched are
potentially numerous.
Therefore, suppress this message when --no-write-fetch-head is passed
(but not when --dry-run is set).

In the common case where users have _not_ pushed a `ci-config` branch to
configure which branches should be included in the GitHub workflow runs,
there is a big fat ugly annotation about a failure in the run's log:
X Check failure on line 1 in .github
@github-actions github-actions / ci-config
.github#L1
Process completed with exit code 128.
The reason is that the `ci-config` job tries to clone that `ci-config`
branch, and even if it is configured to continue on error, the
annotation is displayed, and it is distracting.
Let's just handle this on the shell script level, so that the job's step
is not marked as a failure.

The section added in e76eec35540f (ci: allow per-branch config for
GitHub Actions, 2020-05-07) contains a `&&`-chain that connects several
commands. The first command is actually so long that it stretches over
multiple lines, and as per usual, the continuation lines are indented one
more level than the first.
However, the subsequent commands in the `&&`-chain were also indented
one more level than the first command, which was almost certainly
unintended.

This patch fixes a bug where xrealloc(ptr, 0) can double-free and
corrupt the heap on some platforms (including at least glibc).
The C99 standard says of malloc (section 7.20.3):
If the size of the space requested is zero, the behavior is
implementation-defined: either a null pointer is returned, or the
behavior is as if the size were some nonzero value, except that the
returned pointer shall not be used to access an object.
So we might get NULL back, or we might get an actual pointer (but we're
not allowed to look at its contents). To simplify our code, our
xmalloc() handles a NULL return by converting it into a single-byte
allocation. That way callers get consistent behavior. This was done way
back in 4e7a2eccc2 (?alloc: do not return NULL when asked for zero
bytes, 2005-12-29).
We also gave xcalloc() and xrealloc() the same treatment. And according
to C99, that is fine; the text above is in a paragraph that applies to
all three. But what happens to the memory we passed to realloc() in such
a case? I.e., if we do:
ret = realloc(ptr, 0);
and "ptr" is non-NULL, but we get NULL back, is "ptr" still valid? C99
doesn't cover this case specifically, but says (section 7.20.3.4):
The realloc function deallocates the old object pointed to by ptr and
returns a pointer to a new object that has the size specified by size.
So "ptr" is now deallocated, and we must only look at "ret". And since
"ret" is NULL, that means we have no allocated object at all. But that's
not quite the whole story. It also says:
If memory for the new object cannot be allocated, the old object is
not deallocated and its value is unchanged.
[...]
The realloc function returns a pointer to the new object (which may
have the same value as a pointer to the old object), or a null pointer
if the new object could not be allocated.
So if we see a NULL return with a non-zero size, we can expect that the
original object _is_ still valid. But with a non-zero size, it's
ambiguous. The NULL return might mean a failure (in which case the
object is valid), or it might mean that we successfully allocated
nothing, and used NULL to represent that.
The glibc manpage for realloc() explicitly says:
[...]if size is equal to zero, and ptr is not NULL, then the call is
equivalent to free(ptr).
Likewise, this StackOverflow answer:
https://stackoverflow.com/a/2135302
claims that C89 gave similar guidance (but I don't have a copy to verify
it). A comment on this answer:
https://stackoverflow.com/a/2022410
claims that Microsoft's CRT behaves the same.
But our current "retry with 1 byte" code passes the original pointer
again. So on glibc, we effectively free() the pointer and then try to
realloc() it again, which is undefined behavior.
The simplest fix here is to just pass "ret" (which we know to be NULL)
to the follow-up realloc(). But that means that a system which _doesn't_
free the original pointer would leak it. It's not clear if any such
systems exist, and that interpretation of the standard seems unlikely
(I'd expect a system that doesn't deallocate to simply return the
original pointer in this case). But it's easy enough to err on the safe
side, and just never pass a zero size to realloc() at all.

In fde97d8ac6 (Update documentation to remove incorrect GIT_DIFF_OPTS
example., 2006-11-27), the description of the 'GIT_EXTERNAL_DIFF'
variable was moved from 'diff-format.txt' to 'git.txt', and the
documentation was updated to remove a 'diff(1)' invocation since Git did
not use an external diff program anymore by default.
However, the description of 'GIT_EXTERNAL_DIFF' still mentions "instead
of the diff invocation described above", which is confusing.
Correct that outdated sentence.
Also, link to git(1) in 'diff-generate-patch.txt' when GIT_DIFF_OPTS and
GIT_EXTERNAL_DIFF are mentioned, so that users can easily know what
these variables are about.
