The variable 'option' is used in __git_ps1_show_upstream()
without being localized.
This clobbers the variable the user may be using for other
purposes, which is bad. Luckily, $option is not used to carry
information around in the script as a global variable. The use
of it in this script has very limited scope (namely, only inside
this function), so just declare that it is "local".

The penultimate commit moved the initialization of 'sb.path' in
'builtin/blame.c::cmd_blame' before the call to
'blame.c::setup_blame_bloom_data'. Since 'cmd_blame' is the only caller
of 'setup_blame_bloom_data', it is now unnecessary for
'setup_blame_bloom_data' to receive 'path' as a separate argument, as
'sb.path' is already initialized.
Remove this argument from setup_blame_bloom_data's interface and use the
'path' field of the 'sb' 'struct blame_scoreboard' instead.

In blame.c::cmd_blame, we send the 'path' field of the 'sb' 'struct
blame_scoreboard' as the 'path' argument to
'line-range.c::parse_range_arg', but 'sb.path' is not set yet; it's set
to the local variable 'path' a few lines later at line 1137.
This 'path' argument is only used in 'parse_range_arg' if we are blaming
a funcname, i.e. `git blame -L :<funcname> <path>`, and in that case it
is sent to 'parse_range_funcname', where it is used to determine if a
userdiff driver should be used for said <path> to match the given
funcname.
Since 'path' is yet unset, the userdiff driver is never used, so we fall
back to the default funcname regex, which is usually not appropriate for
paths that are set to use a specific userdiff driver, and thus either we
match some unrelated lines, or we die with
fatal: -L parameter '<funcname>' starting at line 1: no match
This has been the case ever since `git blame` learned to blame a
funcname in 13b8f68c1f (log -L: :pattern:file syntax to find by
funcname, 2013-03-28).
Enable funcname blaming for paths using specific userdiff drivers by
initializing 'sb.path' earlier in 'cmd_blame', when some of its other
fields are initialized, so that it is set when passed to
'parse_range_arg'.
Add a regression test in 'annotate-tests.sh', which is sourced in
t8001-annotate.sh and t8002-blame.sh, leveraging an existing file used
to test the userdiff patterns in t4018-diff-funcname.
Also, use 'sb.path' instead of 'path' when constructing the error
message at line 1114, for consistency.

'git blame -h' and 'git log -h' both show '-L <n,m>' and describe this
option as "Process only line range n,m, counting from 1". No hint is
given that a function name regex can also be used.
Use <range> instead, and expand the description of the option to mention
both modes. Remove "counting from 1" as it's uneeded; it's uncommon to
refer to the first line of a file as "line 0".
Also, for 'git log', improve the wording to better reflect the long help.

Several Git commands can make use of the builtin userdiff patterns, but
it's not obvious in the documentation. Add pointers to the 'Defining a
custom hunk header' part of gitattributes(5) in the description of the
following options:
- the '--function-context' option of `git diff` and friends
- the '--function-context' option of `git grep`
- the '-L :<funcname>' option of `git log`, `gitk` and `git blame`
In 'git-grep.txt', take the opportunity to use backticks in the

'-L :<funcname>' by mentioning it at the beginnning of the description

Also, in 'line-range-options.txt', which is used for git-log(1) and

The description of the '-L' option for `git log` and `gitk` is almost
the same, but is repeated in both 'git-log.txt' and 'gitk.txt' (the
difference being that 'git-log.txt' lists the option with a space
after '-L', while 'gitk.txt' lists it as stuck and notes that `gitk`
only understands the stuck form).
Reduce duplication by creating a new file, 'line-range-options.txt',
and include it in both files.
To simplify the presentation, only list the stuck form for both
commands, and remove the note about `gitk` only understanding the stuck
form.

Calling rev-parse to check if the drop subcommand removed the last stash
and treating its failure as confirmation is fragile, as the command can
fail for other reasons, e.g. because the system is out of memory.
Directly check if the reflog is empty instead, which is more robust.

During stateless packfile negotiation where a depth is given, stateless
RPC clients (e.g. git-remote-curl) will send multiple upload-pack
requests with the first containing only the
wants/shallows/deepens/filters and the subsequent containing haves/done.
When upload-pack handles such requests, entering get_common_commits
without checking whether the client has hung up can result in unexpected
EOF during the negotiation loop and a die() with message "fatal: the
remote end hung up unexpectedly".
Real world effects include:
- A client speaking to git-http-backend via a server that doesn't check
the exit codes of CGIs (e.g. mod_cgi) doesn't know and doesn't care
about the fatal. It continues to process the response body as normal.
- A client speaking to a server that does check the exit code and
returns an errant HTTP status as a result will fail with the message
"error: RPC failed; HTTP 500 curl 22 The requested URL returned error:
500."
- Admins running servers that surface the failure must workaround it by
patching code that handles execution of git-http-backend to ignore exit
codes or take other heuristic approaches.
- Admins may have to deal with "hung up unexpectedly" log spam related
to the failures even in cases where the exit code isn't surfaced as an
HTTP server-side error status.
To avoid these EOF related fatals, have upload-pack gently peek for an
EOF between the sending of shallow/unshallow lines (followed by flush)
and the reading of client haves. If the client has hung up at this
point, exit normally.

Add a new test-tool command named 'fast-rebase', which is a
super-slimmed down and nowhere near as capable version of 'git rebase'.
'test-tool fast-rebase' is not currently planned for usage in the
testsuite, but is here for two purposes:
1) Demonstrate the desired API of merge-ort. In particular,
fast-rebase takes advantage of the separation of the merging
operation from the updating of the index and working tree, to
allow it to pick N commits, but only update the index and working
tree once at the end. Look for the calls to
merge_incore_nonrecursive() and merge_switch_to_result().
2) Provide a convenient benchmark that isn't polluted by the heavy
disk writing and forking of unnecessary processes that comes from
sequencer.c and merge-recursive.c. fast-rebase is not meant to
replace sequencer.c, just give ideas on how sequencer.c can be
changed. Updating sequencer.c with these goals is probably a
large amount of work; writing a simple targeted command with
no documentation, less-than-useful help messages, numerous
limitations in terms of flags it can accept and situations it can
handle, and which is flagged off from users is a much easier
interim step.

A previous commit adjusted the code in ref-filter.c so that messages
containing CRLF are now correctly parsed and displayed.
Add tests to also check that `git log` and `git show` correctly handle
such messages, to prevent futur regressions if these commands are
refactored to use the ref-filter API.

The ref-filter code does not correctly handle commit or tag messages
that use CRLF as the line terminator. Such messages can be created with
the `--cleanup=verbatim` option of `git commit` and `git tag`, or by
using `git commit-tree` directly.
The function `find_subpos` in ref-filter.c looks for two consecutive
LFs to find the end of the subject line, a sequence which is absent in
messages using CRLF. This results in the whole message being parsed as
the subject line (`%(contents:subject)`), and the body of the message
(`%(contents:body)`) being empty.
Moreover, in `copy_subject`, which wants to return the subject as a
single line, '\n' is replaced by space, but '\r' is
untouched.
This impacts the output of `git branch`, `git tag` and `git
for-each-ref`.
This behaviour is a regression for `git branch --verbose`, which
bisects down to 949af0684c (branch: use ref-filter printing APIs,
2017-01-10).
Adjust the ref-filter code to be more lenient by hardening the logic in
`copy_subject` and `find_subpos` to correctly parse messages containing
CRLF.
Add a new test script, 't3920-crlf-messages.sh', to test the behaviour
of commands using either the ref-filter or the pretty APIs with messages
using CRLF line endings. The function `test_crlf_subject_body_and_contents`
can be used to test that the `--format` option of `branch`, `tag`,
`for-each-ref`, `log` and `show` correctly displays the subject, body
and raw content of commit and tag messages using CRLF. Test the
output of `branch`, `tag` and `for-each-ref` with such commits.

In demultiplex_sideband(), there are two oddities when we check an
incoming packet:
- if it has zero length, then we assume it's a flush packet. This
means we fail to notice the difference between a real flush and a
true zero-length packet that's missing its sideband designator. It's
not a huge problem in practice because we'd never send a zero-length
data packet (even our keepalives are otherwise-empty sideband-1
packets).
But it would be nice to detect and report the error, since it's
likely to cause other confusion (we think the other side flushed,
but they do not).
- we try to detect packets missing their designator by checking for
"if (len < 1)". But this will never trigger for "len == 0"; we've
already detected that and left the function before then.
It _could_ detect a negative "len" parameter. But in that case, the
error message is wrong. The issue is not "no sideband" but rather
"eof while reading the packet". However, this can't actually be
triggered in practice, because neither of the two callers uses
pkt_read's GENTLE_ON_EOF flag. Which means they'd die with "the
remote end hung up unexpectedly" before we even get here.
So this truly is dead code.
We can improve these cases by passing in a pkt-line status to the
demultiplexer, and by having recv_sideband() use GENTLE_ON_EOF. This
gives us two improvements:
- we can now reliably detect flush packets, and will report a normal
packet missing its sideband designator as an error
- we'll report an eof with a more detailed "protocol error: eof while
reading sideband packet", rather than the generic "the remote end
hung up unexpectedly"
- when we see an eof, we'll flush the sideband scratch buffer, which
may provide some hints from the remote about why they hung up
(though note we already flush on newlines, so it's likely that most
such messages already made it through)
In some sense this patch goes against fbd76cd450 (sideband: reverse its
dependency on pkt-line, 2019-01-16), which caused the sideband code not
to depend on the pkt-line code. But that commit was really just trying
to deal with the circular header dependency. The two modules are
conceptually interlinked, and it was just trying to keep things
compiling. And indeed, there's a sticking point in this patch: because
pkt-line.h includes sideband.h, we can't add the reverse include we need
for the sideband code to have an "enum packet_read_status" parameter.
Nor can we forward declare it, because you can't forward declare an enum
in C. However, C does guarantee that enums fit in an int, so we can just
use that type.
One alternative would be for the callers to check themselves that they
got something sane from the pkt-line code. But besides duplicating
logic, this gets quite tricky. Any error condition requires flushing the
sideband #2 scratch buffer, which only demultiplex_sideband() knows how
to do.
