send-email: update documentation of required Perl modules
Improve and complete the list of required email related Perl modules,
clarifying which are core Perl modules and remove Net::SMTP::SSL.
git-send-email uses the TLS support in the Net::SMTP core module from
recent versions of Perl. Documenting the minimum version is complex
because of separate numbering for Perl (5.21.5~169), Net:SMTP (2.34)
and libnet (3.01). Version numbers from commit: bfbfc9a953 ("send-email: Net::SMTP::starttls was introduced in v2.34",
2017-05-31).
Users of older Perl versions without Net::SMTP::SSL installed will get a
clear error message.

parse-options: check empty value in OPT_INTEGER and OPT_ABBREV

diff-parseopt: correct variable types that are used by parseopt
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.

p4 unshelve: fix "Not a valid object name HEAD0" on Windows
git p4 unshelve was failing with these errors:
fatal: Not a valid object name HEAD0
Command failed: git cat-file commit HEAD^0
(git version 2.21.0.windows.1, python 2.7.16)
The pOpen call used by git-p4 to invoke the git command can take either a
string or an array as a first argument. The array form is preferred
because platform-specific escaping of special characters will be
handled automatically.(https://docs.python.org/2/library/subprocess.html)
The extractLogMessageFromGitCommit method was, however, using the string
form and so the caret (^) character in the HEAD^0 argument was not being
escaped on Windows. The caret happens to be the escape character, which
is why the git command was receiving HEAD0.
The behaviour can be confirmed by typing ECHO HEAD^0 at the command-
prompt, which emits HEAD0.
The solution is simply to use the array format of passing the command to
fOpen, which is recommended and used in other parts of this code anyway.

clearly stated above the definition (in a comment) that this is so
OBJECT_INFO_FOR_PREFETCH implies OBJECT_INFO_QUICK. The problem is that using
"flag & OBJECT_INFO_FOR_PREFETCH" means that OBJECT_INFO_QUICK also implies
OBJECT_INFO_FOR_PREFETCH.
Split out the single bit from OBJECT_INFO_FOR_PREFETCH into a new
OBJECT_INFO_SKIP_FETCH_OBJECT as the single bit and keep
OBJECT_INFO_FOR_PREFETCH as the union of two flags. This allows a clearer use
of flag checking while also keeping the implication of OBJECT_INFO_QUICK.

mark_fsmonitor_valid(): mark the index as changed if needed
Without this bug fix, t7519's four "status doesn't detect unreported
modifications" test cases would fail occasionally (and, oddly enough,
*a lot* more frequently on Windows).
The reason is that these test cases intentionally use the side effect of
`git status` to re-write the index if any updates were detected: they
first clean the worktree, run `git status` to update the index as well
as show the output to the casual reader, then make the worktree dirty
again and expect no changes to reported if running with a mocked
fsmonitor hook.
The problem with this strategy was that the index was written during
said `git status` on the clean worktree for the *wrong* reason: not
because the index was marked as changed (it wasn't), but because the
recorded mtimes were racy with the index' own mtime.
As the mtime granularity on Windows is 100 nanoseconds (see e.g.
https://docs.microsoft.com/en-us/windows/desktop/SysInfo/file-times),
the mtimes of the files are often enough *not* racy with the index', so
that that `git status` call currently does not always update the index
(including the fsmonitor extension), causing the test case to fail.
The obvious fix: if we change *any* index entry's `CE_FSMONITOR_VALID`
flag, we should also mark the index as changed. That will cause the
index to be written upon `git status`, *including* an updated fsmonitor
extension.
Side note: Even though the reader might think that the t7519 issue
should be *much* more prevalent on Linux, given that the ext4 filesystem
(that seems to be used by every Linux distribution) stores mtimes in
nanosecond precision. However, ext4 uses `current_kernel_time()` (see
https://unix.stackexchange.com/questions/11599#comment762968_11599; it
is *amazingly* hard to find any proper source of information about such
ext4 questions) whose accuracy seems to depend on many factors but is
safely worse than the 100-nanosecond granularity of NTFS (again, it is
*horribly* hard to find anything remotely authoritative about this
question). So it seems that the racy index condition that hid the bug
fixed by this patch simply is a lot more likely on Linux than on
Windows. But not impossible ;-)

The protocol documentation states that the command must come first. The
Git server implementation in serve.c (see process_request() in that

why we haven't noticed this. This was noticed when testing against a

grep_source(), which performs much of the work for Git's grep library,
allows passing an arbitrary struct grep_source which represents the text
which grep_source() should search to match a pattern in the provided
struct grep_opt. In most callers, the grep_source::name field is set to
an appropriate prefix to print before a colon when a result matches:
README:Git is an Open Source project covered by the GNU General
One caller, grep_buffer(), leaves the grep_source::name field set to
NULL because there isn't enough context to determine an appropriate name
for this kind of output line. In practice, this has been fine: the only
caller of grep_buffer() is "git log --grep", and that caller sets
grep_opt::status_only, which disables output and only checks whether a
match exists. But this is brittle: a future caller can call
grep_buffer() without grep_opt::status_only set, and as soon as it hits
a match, grep_source() will try to print the match and segfault:
(null):Git is an Open Source project covered by the GNU General
For example, a future caller might want to print all matching lines from
commits which match a regex.
Futureproof by diagnosing early a use of the API that could trigger that
condition, before we know whether the pattern matches:
BUG: grep.c:1783: grep call which could print a name requires
grep_source.name be non-NULL
Aborted
This way, the caller's author gets an indication of how to fix the issue
- by providing grep_source::name or setting grep_opt::status_only - and
they are warned of the potential for a segfault unconditionally, rather
than only if there is a match.

In --interactive mode, "git am --resolved" will try to generate a patch
based on what is in the index, so that it can prompt "apply this
patch?". To do so it needs the tree of HEAD, which it tries to get with
get_oid_tree(). However, this doesn't yield a tree object; the "tree"
part just means "if you must disambiguate short oids, then prefer trees"
(and we do not need to disambiguate at all, since we are feeding a ref).
Instead, we must parse the oid as a commit (which should always be true
in a non-corrupt repository), and access its tree pointer manually.
This has been broken since the conversion to C in 7ff2683253
(builtin-am: implement -i/--interactive, 2015-08-04), but there was no
test coverage because of interactive-mode's insistence on having a tty.
That was lifted in the previous commit, so we can now add a test for
this case.
Note that before this patch, the test would result in a BUG() which
comes from 3506dc9445 (has_uncommitted_changes(): fall back to empty
tree, 2018-07-11). But before that, we'd have simply segfaulted (and in

We have required that the stdin of "am --interactive" be a tty since a1451104ac (git-am: interactive should fail gracefully., 2005-10-12).
However, this isn't strictly necessary, and makes the tool harder to
test (and is unlike all of our other --interactive commands).
The goal of that commit was to make sure that somebody does not do:
git am --interactive <mbox
and cause us to read commands from the mbox. But we can simply check
up front for this case and complain before entering the interactive
loop.
Technically this disallows:
git am --interactive </dev/null
where our lack of patches means we would never prompt for anything, and
so the old code would not notice our lack of tty (and now we'd die
early). But since such a command is totally pointless, it's no loss.

In the conversion of git-am from shell script to C, we switched to using
git_prompt(). Unlike the original shell command "read reply", this
doesn't read from stdin at all, but rather from /dev/tty.
In most cases this distinction wouldn't matter. We require (as the shell
script did) that stdin is a tty, so they would generally be the same
thing. But one important exception is our test suite: even with
test_terminal, we cannot test "am --interactive" because it insists on
reading from /dev/tty, not the pseudo-tty we've set up in the test
script.
Fixing this clears the way to adding tests in a future patch.

doesn't make sense to continue; on a true terminal hangup we'd just loop
infinitely trying to get input that will never come.

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: 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.

Since 7171d8c15f (upload-pack: send symbolic ref information as
capability, 2013-09-17), we've sent cloning and fetching clients special
information about which branch HEAD is pointing to, so that they don't
have to guess based on matching up commit ids.
However, this feature has never worked properly with the GIT_NAMESPACE
feature. Because upload-pack uses head_ref_namespaced(find_symref), we
do find and report on refs/namespaces/foo/HEAD instead of the actual
HEAD of the repo. This makes sense, since the branch pointed to by the
top-level HEAD may not be advertised at all. But we do two things wrong:
1. We report the full name refs/namespaces/foo/HEAD, instead of just
HEAD. Meaning no client is going to bother doing anything with that
symref, since we're not otherwise advertising it.
2. We report the symref destination using its full name (e.g.,
refs/namespaces/foo/refs/heads/master). That's similarly useless to
the client, who only saw "refs/heads/master" in the advertisement.
We should be stripping the namespace prefix off of both places (which
this patch fixes).
Likely nobody noticed because we tend to do the right thing anyway. Bug
(1) means that we said nothing about HEAD (just refs/namespace/foo/HEAD).
And so the client half of the code, from a45b5f0552 (connect: annotate
refs with their symref information in get_remote_head(), 2013-09-17),
does not annotate HEAD, and we use the fallback in guess_remote_head(),
matching refs by object id. Which is usually right. It only falls down
in ambiguous cases, like the one laid out in the included test.
This also means that we don't have to worry about breaking anybody who
was putting pre-stripped names into their namespace symrefs when we fix
bug (2). Because of bug (1), nobody would have been using the symref we
advertised in the first place (not to mention that those symrefs would
have appeared broken for any non-namespaced access).
Note that we have separate fixes here for the v0 and v2 protocols. The
symref advertisement moved in v2 to be a part of the ls-refs command.
This actually gets part (1) right, since the symref annotation
piggy-backs on the existing ref advertisement, which is properly
stripped. But it still needs a fix for part (2). The included tests
cover both protocols.

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.

The fsmonitor interface got out of sync after the in-core index
file gets discarded, which has been corrected.

fsmonitor: demonstrate that it is not refreshed after discard_index()
To run tests for Git SVN, our scripts for CI used to install the
git-svn package (in the hope that it would bring in the right
dependencies). This has been updated to install the more direct
dependency, namely, libsvn-perl.
* sg/ci-libsvn-perl:
ci: install 'libsvn-perl' instead of 'git-svn'
On a filesystem like HFS+, the names of the refs stored as filesystem
entities may become different from what the end-user expects, just
like files in the working tree get "renamed". Work around the
mismatch by paying attention to the core.precomposeUnicode
configuration.

Honor core.precomposeUnicode in more places
Update "git difftool" and "git mergetool" so that the combinations
of {diff,merge}.{tool,guitool} configuration variables serve as
fallback settings of each other in a sensible order.
* dl/difftool-mergetool:
difftool: fallback on merge.guitool
difftool: make --gui, --tool and --extcmd mutually exclusive
mergetool: fallback to tool when guitool unavailable
mergetool--lib: create gui_mode function
mergetool: use get_merge_tool function
t7610: add mergetool --gui tests

Attempt to use an abbreviated option in "git clone --recurs" is
responded by a request to disambiguate between --recursive and
--recurse-submodules, which is bad because these two are synonyms.
The parse-options API has been extended to define such synonyms
more easily and not produce an unnecessary failure.

parse-options: don't emit "ambiguous option" for aliases
"git branch new A...B" and "git checkout -b new A...B" have been
taught that in their contexts, the notation A...B means "the merge
base between these two commits", just like "git checkout A...B"
detaches HEAD at that commit.

Performance test framework has been broken and measured the version
of Git that happens to be on $PATH, not the specified one to
