The value returned by getenv() is not guaranteed to remain valid across
other environment function calls. But in between our call and using the
value, we run fill_textconv(), which may do quite a bit of work,
including spawning sub-processes.
We can make this safer by calling getenv() right before we actually look
at its value.

If $GITHEAD_1234abcd is set in the environment, we use its value as a
"better branch name" in generating conflict markers. However, we pick
these better names early in the process, and the return value from
getenv() is not guaranteed to stay valid.
Let's make a copy of the returned string. And to make memory management
easier, let's just always return an allocated string from
better_branch_name(), so we know that it must always be freed.

We pass the result of getenv("GIT_DIR") to init_db() and assume that the
string remains valid. But that's not guaranteed across calls to setenv()
or even getenv(), although it often works in practice. Let's make a copy
of the string so that we follow the rules.
Note that we need to mark it with UNLEAK(), since the value persists
until the end of program (but we have no opportunity to free it).
This patch also handles $GIT_WORK_TREE the same way. It actually doesn't
have as long a lifetime and is probably fine, but it's simpler to just
treat the two side-by-side variables the same.

cmd_config() points our source filename pointer at the return value of

We save the result of $GIT_INDEX_FILE so that we can restore it after
setting it to a new value and running add--interactive. However, the
pointer returned by getenv() is not guaranteed to be valid after calling
setenv(). This _usually_ works fine, but can fail if libc needs to
reallocate the environment block during the setenv().
Let's just duplicate the string, so we know that it remains valid.
In the long run it may be more robust to teach interactive_add() to take
a set of environment variables to pass along to run-command when it
execs add--interactive. And then we would not have to do this
save/restore dance at all. But this is an easy fix in the meantime.

The return value of getenv() is not guaranteed to remain valid across
multiple calls (nor across calls to setenv()). Since this function
caches the result for the length of the program, we must make a copy to

According to getenv(3)'s notes:
The implementation of getenv() is not required to be reentrant. The
string pointed to by the return value of getenv() may be statically
allocated, and can be modified by a subsequent call to getenv(),
putenv(3), setenv(3), or unsetenv(3).
Since strings returned by getenv() are allowed to change on subsequent
calls to getenv(), make sure to duplicate when caching external_diff_cmd
from environment.
This problem becomes apparent on Git for Windows since fe21c6b285df
(mingw: reencode environment variables on the fly (UTF-16 <-> UTF-8)),
when the getenv() implementation provided in compat/mingw.c was changed
to keep a certain amount of alloc'ed strings and freeing them on
subsequent calls.
This fixes https://github.com/git-for-windows/git/issues/2007:

On Windows, files cannot be removed nor renamed if there are still
handles held by a process. To remedy that, we introduced the
close_all_packs() function.
Earlier, we made sure that the packs are released just before `git gc`
is spawned, in case that gc wants to remove no-longer needed packs.
But this developer forgot that gc itself also needs to let go of packs,
e.g. when consolidating all packs via the --aggressive option.
Likewise, `git repack -d` wants to delete obsolete packs and therefore
needs to close all pack handles, too.

When the scaffolding for protocol version 2 was initially added in
8f6982b4e1 ("protocol: introduce enum protocol_version value
protocol_v2", 2018-03-14). As seen in:
git log -p -G'support for protocol v2 not implemented yet' --full-diff --reverse v2.17.0..v2.20.0
Many of those scaffolding "die" placeholders were removed, but we
hadn't gotten around to fetch-pack yet.
The test here for "fetch refs from cmdline" is very minimal. There's
much better coverage when running the entire test suite under the WIP
GIT_TEST_PROTOCOL_VERSION=2 mode[1], we should ideally have better
coverage without needing to invoke a special test mode.

In the v2 protocol, upload-pack's advertisement has been moved to the
"ls-refs" command. That command does not respect hidden-ref config (like
transfer.hiderefs) at all, and advertises everything.
While there are some features that are not supported in v2 (e.g., v2
always allows fetching any sha1 without respect to advertisements), the
lack of this feature is not documented and is likely just a bug. Let's
make it work, as otherwise upgrading a server to a v2-capable git will
start exposing these refs that the repository admin has asked to remain
hidden.
Note that we assume we're operating on behalf of a fetch here, since
that's the only thing implemented in v2 at this point. See the in-code
comment. We'll have to figure out how this works when the v2 push
protocol is designed (both here in ls-refs, but also rejecting updates
to hidden refs).

When using --color-moved-ws=allow-indentation-change allow lines with
the same indentation change to be grouped across blank lines. For now
this only works if the blank lines have been moved as well, not for
blocks that have just had their indentation changed.
This completes the changes to the implementation of
--color-moved=allow-indentation-change. Running
git diff --color-moved=allow-indentation-change v2.18.0 v2.19.0
now takes 5.0s. This is a saving of 41% from 8.5s for the optimized
version of the previous implementation and 66% from the original which
took 14.6s.

Currently diff --color-moved-ws=allow-indentation-change does not
support indentation that contains a mix of tabs and spaces. For
example in commit 546f70f377 ("convert.h: drop 'extern' from function
declaration", 2018-06-30) the function parameters in the following
lines are not colored as moved [1].
-extern int stream_filter(struct stream_filter *,
- const char *input, size_t *isize_p,
- char *output, size_t *osize_p);
+int stream_filter(struct stream_filter *,
+ const char *input, size_t *isize_p,
+ char *output, size_t *osize_p);
This commit changes the way the indentation is handled to track the
visual size of the indentation rather than the characters in the
indentation. This has the benefit that any whitespace errors do not
interfer with the move detection (the whitespace errors will still be
highlighted according to --ws-error-highlight). During the discussion
of this feature there were concerns about the correct detection of
indentation for python. However those concerns apply whether or not
we're detecting moved lines so no attempt is made to determine if the
indentation is 'pythonic'.
[1] Note that before the commit to fix the erroneous coloring of moved
lines each line was colored as a different block, since that commit
they are uncolored.

When running
git diff --color-moved-ws=allow-indentation-change v2.18.0 v2.19.0
cmp_in_block_with_wsd() is called 694908327 times. Of those 42.7%
return after comparing a and b. By comparing the lengths first we can
return early in all but 0.03% of those cases without dereferencing the
string pointers. The comparison between a and c fails in 6.8% of
calls, by comparing the lengths first we reject all the failing calls
without dereferencing the string pointers.
This reduces the time to run the command above by by 42% from 14.6s to
8.5s. This is still much slower than the normal --color-moved which
takes ~0.6-0.7s to run but is a significant improvement.
The next commits will replace the current implementation with one that
works with mixed tabs and spaces in the indentation. I think it is
worth optimizing the current implementation first to enable a fair
comparison between the two implementations.

Currently when using --color-moved=zebra the color of moved blocks
depends on the number of lines separating them. This means that adding
an odd number of unmoved lines between blocks that are already separated
by one or more unmoved lines will change the color of subsequent moved
blocks. This does not make much sense as the blocks were already
separated by unmoved lines and causes problems when adding lines to test
cases.
Fix this by only using the alternate colors for adjacent moved blocks.

'diff --color-moved-ws=allow-indentation-change' can color lines as
moved when they are in fact different. For example in commit
1a07e59c3e ("Update messages in preparation for i18n", 2018-07-21) the
lines
- die (_("must end with a color"));
+ die(_("must end with a color"));
are colored as moved even though they are different.
This is because if there is a fuzzy match for the first line of
a potential moved block the line is marked as moved before the
potential match is checked to see if it actually matches. The fix is
to delay marking the line as moved until after we have checked that
there really is at least one matching potential moved block.
Note that the test modified in the last commit still fails because
adding an unmoved line between two moved blocks that are already
separated by unmoved lines changes the color of the block following the
addition. This should not be the case and will be fixed in the next
commit.

The loose objects cache is filled one subdirectory at a time as needed.
It is stored in an oid_array, which has to be resorted after each add
operation. So when querying a wide range of objects, the partially
filled array needs to be resorted up to 255 times, which takes over 100
times longer than sorting once.
Use one oid_array for each subdirectory. This ensures that entries have
to only be sorted a single time. It also avoids eight binary search
steps for each cache lookup as a small bonus.
The cache is used for collision checks for the log placeholders %h, %t
and %p, and we can see the change speeding them up in a repository with
ca. 100 objects per subdirectory:

Uninitialized submodules have nothing valueable for us to be worried
about. They are just SHA-1. Let "worktree remove" and "worktree move"
continue in this case so that people can still use multiple worktrees
on repos with optional submodules that are never populated, like
sha1collisiondetection in git.git when checked out by doc-diff script.
Note that for "worktree remove", it is possible that a user
initializes a submodule (*), makes some commits (but not push), then
deinitializes it. At that point, the submodule is unpopulated, but the
precious new commits are still in
$GIT_COMMON_DIR/worktrees/<worktree>/modules/<submodule>
directory and we should not allow removing the worktree or we lose
those commits forever. The new directory check is added to prevent
this.
(*) yes they are screwed anyway by doing this since "git submodule"
would add submodule.* in $GIT_COMMON_DIR/config, which is shared
across multiple worktrees. But it does not mean we let them be
screwed even more.

Unfortunately, we have a few flaky tests, whose failures tend to be
hard to reproduce. We've found that the best we can do to reproduce
such a failure is to run the test script repeatedly while the machine
is under load, and wait in the hope that the load creates enough
variance in the timing of the test's commands that a failure is
evenually triggered. I have a command to do that, and I noticed that
two other contributors have rolled their own scripts to do the same,
all choosing slightly different approaches.
To help reproduce failures in flaky tests, introduce the '--stress'
option to run a test script repeatedly in multiple parallel jobs until
one of them fails, thereby using the test script itself to increase
the load on the machine.
The number of parallel jobs is determined by, in order of precedence:
the number specified as '--stress=<N>', or the value of the
GIT_TEST_STRESS_LOAD environment variable, or twice the number of
available processors (as reported by the 'getconf' utility), or 8.
Make '--stress' imply '--verbose -x --immediate' to get the most
information about rare failures; there is really no point in spending
all the extra effort to reproduce such a failure, and then not know
which command failed and why.
To prevent the several parallel invocations of the same test from
interfering with each other:
- Include the parallel job's number in the name of the trash
directory and the various output files under 't/test-results/' as
a '.stress-<Nr>' suffix.
- Add the parallel job's number to the port number specified by the
user or to the test number, so even tests involving daemons
listening on a TCP socket can be stressed.
- Redirect each parallel test run's verbose output to
't/test-results/$TEST_NAME.stress-<nr>.out', because dumping the
output of several parallel running tests to the terminal would
create a big ugly mess.
For convenience, print the output of the failed test job at the end,
and rename its trash directory to end with the '.stress-failed'
suffix, so it's easy to find in a predictable path (OTOH, all absolute
paths recorded in the trash directory become invalid; we'll see
whether this causes any issues in practice). If, in an unlikely case,
more than one jobs were to fail nearly at the same time, then print
the output of all failed jobs, and rename the trash directory of only
the last one (i.e. with the highest job number), as it is the trash
directory of the test whose output will be at the bottom of the user's
terminal.
Based on Jeff King's 'stress' script.

Several test scripts run daemons like 'git-daemon' or Apache, and
communicate with them through TCP sockets. To have unique ports where
these daemons are accessible, the ports are usually the number of the
corresponding test scripts, unless the user overrides them via
environment variables, and thus all those tests and test libs contain
more or less the same bit of one-liner boilerplate code to find out
the port. The last patch in this series will make this a bit more
complicated.
Factor out finding the port for a daemon into the common helper
function 'test_set_port' to avoid repeating ourselves.
Take special care of test scripts with "low" numbers:
- Test numbers below 1024 would result in a port that's only usable
as root, so set their port to '10000 + test-nr' to make sure it
doesn't interfere with other tests in the test suite. This makes
the hardcoded port number in 't0410-partial-clone.sh' unnecessary,
remove it.
- The shell's arithmetic evaluation interprets numbers with leading
zeros as octal values, which means that test number below 1000 and
containing the digits 8 or 9 will trigger an error. Remove all
leading zeros from the test numbers to prevent this.
Note that the 'git p4' tests are unlike the other tests involving
daemons in that:
- 'lib-git-p4.sh' doesn't use the test's number for unique port as
is, but does a bit of additional arithmetic on top [1].
- The port is not overridable via an environment variable.
With this patch even 'git p4' tests will use the test's number as
default port, and it will be overridable via the P4DPORT environment
variable.
[1] Commit fc00233071 (git-p4 tests: refactor and cleanup, 2011-08-22)
introduced that "unusual" unique port computation without
explaining why it was necessary (as opposed to simply using the
test number as is). It seems to be just unnecessary complication,
and in any case that commit came way before the "test nr as unique
port" got "standardized" for other daemons in commits c44132fcf3
(tests: auto-set git-daemon port, 2014-02-10), 3bb486e439 (tests:
auto-set LIB_HTTPD_PORT from test name, 2014-02-10), and
bf9d7df950 (t/lib-git-svn.sh: improve svnserve tests with parallel
make test, 2017-12-01).

A later patch in this series will need to know the path to the trash
directory early in 'test-lib.sh', but $TRASH_DIRECTORY is set much
later.
Set $TRASH_DIRECTORY earlier, where the other test-specific path
variables are set.

There are two places where we strip off any leading path components
and the '.sh' suffix from the test script's pathname, and there are
four places where we construct the name of the 't/test-results'
directory or the name of various test-specific files in there. The
last patch in this series will add even more.
Factor these out into helper variables to avoid repeating ourselves.

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. It looks for '--valgrind' as well, to
set up some Valgrind-specific stuff. These all happen before the
actual option parsing loop, and the conditions looking for these
options look a bit odd, too. They are not completely correct, either,
because in a bogus invocation like './t1234-foo.sh -r --tee' they
recognize '--tee', although it should be handled as the required
argument of the '-r' option. This patch series will add two more
options to look out for early, and, in addition, will have to extract
these options' stuck arguments (i.e. '--opt=arg') as well.
So let's move the option parsing loop and the couple of related
conditions following it earlier in 'test-lib.sh', before the place
where the test script is executed again for '--tee' and its friends.

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error, and to do so it needs the original
command line options the test was invoked with.
The next patch is about to move the option parsing loop earlier in
'test-lib.sh', but it is implemented using 'shift' in a while loop,
effecively destroying "$@" by the end of the option parsing. Not
good.
As a preparatory step, turn that option parsing loop into a 'for opt
in "$@"' loop to preserve "$@" intact while iterating over the
options, and taking extra care to handle the '-r' option's required
argument (or the lack thereof).

One of our test scripts, 't1510-repo-setup.sh' [1], still can't be
reliably run with '-x' tracing enabled, unless it's executed with a
Bash version supporting BASH_XTRACEFD (since v4.1). We have a lengthy
condition to check the version of the shell running the test script,
and disable tracing if it's not executed with a suitable Bash version
[2].
Move this check out from the option parsing loop, so other options can
imply '-x' by setting 'trace=t', without missing this Bash version
check.

801fa63a90 ("config.mak.dev: add -Wformat-security", 2018-09-08)
added the "-Wformat-security" to the flags set in config.mak.dev.
In the gcc man page this is documented as:
If -Wformat is specified, also warn about uses of format
functions that represent possible security problems. [...]
The commit did however not add the "-Wformat" flag, but instead
relied on the fact that "-Wall" is set in the Makefile by default
and that "-Wformat" is part of "-Wall".
Unfortunately, those who use config.mak.autogen generated with the
autoconf to configure toolchain do *not* get "-Wall" in their CFLAGS
and the added -Wformat-security had no effect. Worse yet, newer
versions of gcc (gcc 8.2.1 in this particular case) warn about the
lack of "-Wformat" and thus compilation fails only with this option
set.
We could fix it by adding "-Wformat", but in general we do want all
checks included in "-Wall", so let's add it to config.mak.dev to
cover more cases.

map_sha1_file_1() checks if the file it is about to mmap() is empty and
errors out in that case and explains the situation in an error message.
It leaks the private handle to that empty file, though.
Have the function clean up after itself and close the file descriptor
before exiting early.
