Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:
+brew link gcc@8
Error: No such keg: /usr/local/Cellar/gcc@8
The command "ci/install-dependencies.sh" failed and exited with 1 during .
Now, while gcc@8 is still pre-installed (but not linked) and would be
perfectly usable in the Travis CI macOS image we use [1], it's at
version 8.2. However, when installing dependencies we first
explicitly run 'brew update', which spends over two minutes to update
itself and information about the available packages, and it learns
about GCC 8.3. After that point gcc@8 exclusively refers to v8.3,
and, unfortunately, 'brew' is just too dumb to be able to do anything
with the still installed 8.2 package, and the subsequent 'brew link
gcc@8' fails. (Even 'brew uninstall gcc@8' fails with the same
error!)
Don't run 'brew update' to keep the already installed GCC 8.2 'brew
link'-able. Note that in addition we have to 'export
HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful
that it would implicitly run update for us on the next 'brew install
<pkg>' otherwise.
Disabling 'brew update' has additional benefits:
- It shaves off 2-3mins from the ~4mins currently spent on
installing dependencies, and the macOS build jobs have always been
prone to exceeding the time limit on Travis CI.
- Our builds won't suddenly break because of the occasional Homebrew
breakages [2].
The drawback is that we'll be stuck with slightly older versions of
the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce
2018.1; they are currently at 2.7.2 and 2019.1, respectively). We
might want to reconsider this decision as time goes on and/or switch
to a more recent macOS image as they become available.

merge-recursive: restore accidentally dropped setting of path
In commit 8daec1df03de ("merge-recursive: switch from (oid,mode) pairs
to a diff_filespec", 2019-04-05), we actually switched from
(oid,mode,path) triplets to a diff_filespec -- but most callsites in the
patch only needed to worry about oid and mode so the commit message
focused on that. The oversight in the commit message apparently spilled
over to the code as well; one of the dozen or so callsites accidentally
dropped the setting of the path in the conversion. Restore the path
setting in that location.
Also, this pointed out that our testsuite was lacking a good rename/add
test, at least one that involved the need for merge content with the
rename. Add such a test, and since rename/add vs. add/rename could
possibly be important, redo the merge the opposite direction to make
sure we don't have issues with the direction of the merge. These
testcases failed before restoring the setting of path, but with the
paths appropriately set the testcases both pass.

If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.
So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.
If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.
For now though, let's just disable 'sparse:path' filters.

parse-options: check empty value in OPT_INTEGER and OPT_ABBREV
When parsing the argument for OPT_INTEGER and OPT_ABBREV, we check if we
can parse the entire argument to a number with "if (*s)". There is one
missing check: if "arg" is empty to begin with, we fail to notice.
This could happen with long option by writing like
git diff --inter-hunk-context= blah blah
Before 16ed6c97cc (diff-parseopt: convert --inter-hunk-context,
2019-03-24), --inter-hunk-context is handled by a custom parser
opt_arg() and does detect this correctly.
This restores the bahvior for --inter-hunk-context and make sure all
other integer options are handled the same (sane) way. For OPT_ABBREV
this is new behavior. But it makes it consistent with the rest.
PS. OPT_MAGNITUDE has similar code but git_parse_ulong() does detect
empty "arg". So it's good to go.

Before d473e2e0e8 (diff.c: convert -U|--unified, 2019-01-27), -U and
--unified are implemented with a custom parser opt_arg() in diff.c. I
didn't check this code carefully and not realize that it's the
equivalent of PARSE_OPT_NONEG | PARSE_OPT_OPTARG.
In other words, if -U is specified without any argument, the option
should be accepted, and the default value should be used. Without
PARSE_OPT_OPTARG, parse_options() will reject this case and cause a
regression.

diff-parseopt: correct variable types that are used by parseopt
Most number-related OPT_ macros store the value in an 'int'
variable. Many of the variables in 'struct diff_options' have a
different type, but during the conversion to using parse_options() I
failed to notice and correct.
The problem was reported on s360x which is a big-endian
architechture. The variable to store '-w' option in this case is
xdl_opts, 'long' type, 8 bytes. But since parse_options() assumes
'int' (4 bytes), it will store bits in the wrong part of xdl_opts. The
problem was found on little-endian platforms because parse_options()
will accidentally store at the right part of xdl_opts.
There aren't much to say about the type change (except that 'int' for
xdl_opts should still be big enough, since Windows' long is the same
size as 'int' and nobody has complained so far). Some safety checks may
be implemented in the future to prevent class of bugs.

As of Git v2.22.0, the `--preserve-merges` backend of `git rebase` will

tests: mark a couple more test cases as requiring `rebase -p`

Currently, if any server options are specified during a protocol v2
fetch, server options will be sent before "command=fetch". Write server
options to the request buffer in send_fetch_request() so that the
components of the request are sent in the correct order.
The protocol documentation states that the command must come first. The
Git server implementation in serve.c (see process_request() in that
file) tolerates any order of command and capability, which is perhaps
why we haven't noticed this. This was noticed when testing against a
JGit server implementation, which follows the documentation in this
regard.

progress: avoid empty line when breaking the progress line
Since commit 545dc345eb (progress: break too long progress bar lines,
2019-04-12) when splitting a too long progress line, sometimes it
looks as if a superfluous empty line were added between the title
line and the counters.
To make sure that the previously displayed progress line is completely
covered up when writing the new, shorter title line, we calculate how
many characters need to be overwritten with spaces. Alas, this
calculation doesn't account for the newline character at the end of
the new title line, and resulted in printing one more space than
strictly necessary. This extra space character doesn't matter, if the
length of the previous progress line was shorter than the width of the
terminal. However, if the previous line matched the terminal width,
then this extra space made the new line longer, effectively adding
that empty line after the title line.
Fix this off-by-one to avoid that spurious empty line.

trace2: document the supported values of GIT_TRACE2* env variables
The descriptions of the GIT_TRACE2* environment variables link to the
technical docs for further details on the supported values. However,
a link like this only really works if the docs are viewed in a browser
and the full documentation is available. OTOH, in 'man git' there are
no links to conveniently click on, and distro-shipped git packages
tend to include only the man pages, while the technical docs and the
docs in html format are in a separate 'git-doc' package.
So let's describe the supported values to make the manpage more
self-contained, but still keep the references to the technical docs
because the details of the SID, and the JSON and perf output formats
are definitely beyond the scope of 'man git'.

trace2: rename environment variables to GIT_TRACE2*
For an environment variable that is supposed to be set by users, the
GIT_TR2* env vars are just too unclear, inconsistent, and ugly.
Most of the established GIT_* environment variables don't use
abbreviations, and in case of the few that do (GIT_DIR,
GIT_COMMON_DIR, GIT_DIFF_OPTS) it's quite obvious what the
abbreviations (DIR and OPTS) stand for. But what does TR stand for?
Track, traditional, trailer, transaction, transfer, transformation,
transition, translation, transplant, transport, traversal, tree,
trigger, truncate, trust, or ...?!
The trace2 facility, as the '2' suffix in its name suggests, is
supposed to eventually supercede Git's original trace facility. It's
reasonable to expect that the corresponding environment variables
follow suit, and after the original GIT_TRACE variables they are
called GIT_TRACE2; there is no such thing is 'GIT_TR'.
All trace2-specific config variables are, very sensibly, in the
'trace2' section, not in 'tr2'.
OTOH, we don't gain anything at all by omitting the last three
characters of "trace" from the names of these environment variables.
So let's rename all GIT_TR2* environment variables to GIT_TRACE2*,
before they make their way into a stable release.

There appears to be a bug in the toolchain generating manpages from
lettered lists. When a list is enumerated with letters, the resulting
nroff shows numbers instead. Mostly this is harmless, but in the case of
gitsubmodules, the paragraph following the list refers back to each
bullet by letter. As a result, reading this documentation via `man
gitsubmodules` is hard to parse - readers must infer that a bug exists
and a refers to 1, b refers to 2, and c refers to 3 in the list above.
The problem specifically was introduced in ad47194; previously rather
than generating numerated lists the bulleted area was entirely
monospaced in HTML and shown in plaintext in nroff.
The bug seems to exist in docbook-xml - I've reported it on May 1 via
the docbook-apps mail list - but for now it may make more sense to just
work around the issue.
