The test '--no-show-forced-updates' in 't5510-fetch.sh' added in cdbd70c437 (fetch: add --[no-]show-forced-updates argument,
2019-06-18) runs '! test_i18ngrep ...'. This is wrong, because when
running the test with GIT_TEST_GETTEXT_POISON=true, then
'test_i18ngrep' is basically a noop and always returns with success,
the leading ! turns that into a failure, which then fails the test.
Use 'test_i18ngrep ! ...' instead.
This went unnoticed by our GETTEXT_POISON CI builds, because those
builds don't run this test case: in those builds we don't install
Apache, and this test comes after 't5510' sources 'lib-httpd.sh',
which, consequently, skips all the remaining tests, including this
one.

The commit-graph file is now part of the "files that the runtime

"git submodule foreach" did not protect command line options passed

submodule foreach: fix recursion of options
Merge branch 'js/rebase-reschedule-applies-only-to-interactive' into maint
The configuration variable rebase.rescheduleFailedExec should be
effective only while running an interactive rebase and should not

Merge branch 'jc/denoise-rm-to-resolve' into maint

"needs merge" before actually removing the path, which was
confusing. This has been corrected.

rm: resolving by removal is not a warning-worthy event
Merge branch 'es/local-atomic-push-failure-with-http' into maint

upload-pack: strip namespace from symref data
Merge branch 'mh/import-transport-fd-fix' into maint
The ownership rule for the file descriptor to fast-import remote

closed, which has been fixed.

Use xmmap_gently instead of xmmap in use_pack
dup() the input fd for fast-import used for remote helpers
Merge branch 'nd/init-relative-template-fix' into maint
A relative pathname given to "git init --template=<path> <repo>"

corrected.

The "git log" command learns to issue a warning when log.mailmap
configuration is not set and --[no-]mailmap option is not used, to
prepare users for future versions of Git that uses the mailmap by
default.
* ac/log-use-mailmap-by-default-transition:

Many GIT_TEST_* environment variables control various aspects of
how our tests are run, but a few followed "non-empty is true, empty
or unset is false" while others followed the usual "there are a few
ways to spell true, like yes, on, etc., and also ways to spell
false, like no, off, etc." convention.
* ab/test-env:
env--helper: mark a file-local symbol as static

xdiff: clamp function context indices in post-image
After finding a function line for --function-context in the pre-image,
xdl_emit_diff() calculates the equivalent line in the post-image. It
assumes that the lines between changes are the same on both sides. If
the option --ignore-blank-lines was also given then this is not
necessarily true.
Clamp the calculation results for start and end of the function context
to prevent out-of-bounds array accesses.
Note that this _just_ fixes the case where our mismatch sends us off the
beginning of the file. There are likely other cases where our assumption
causes us to go to the wrong line within the file. Nobody has developed
a test case yet, and the ultimate fix is likely more complicated than
this patch. But this at least prevents a segfault in the meantime.
Credit for finding the bug goes to "Liu Wei of Tencent Security Xuanwu
Lab".

C99 'for' loop initial declaration, i.e. 'for (int i = 0; i < n; i++)',
is not allowed in Git's codebase yet, to maintain compatibility with
some older compilers.
Our Travis CI builds used to catch 'for' loop initial declarations,
because the GETTEXT_POISON job has always built Git with the default
'cc', which in Travis CI's previous default Linux image (based on
Ubuntu 14.04 Trusty) is GCC 4.8, and that GCC version errors out on
this construct (not only with DEVELOPER=1, but with our default CFLAGS
as well). Alas, that's not the case anymore, becase after 14.04's EOL
Travis CI's current default Linux image is based on Ubuntu 16.04
Xenial [1] and its default 'cc' is now GCC 5.4, which, just like all
later GCC and Clang versions, simply accepts this construct, even if
we don't explicitly specify '-std=c99'.
Ideally we would adjust our CFLAGS used with DEVELOPER=1 to catch this
undesired construct already when contributors build Git on their own
machines. Unfortunately, however, there seems to be no compiler
option that would catch only this particular construct without choking
on many other things, e.g. while a later compiler with '-std=c90'
and/or '-ansi' does catch this construct, it can't build Git because
of several screenfulls of other errors.
Add the 'linux-gcc-4.8' job to Travis CI, in order to build Git with
GCC 4.8, and thus to timely catch any 'for' loop initial declarations.
To catch those it's sufficient to only build Git with GCC 4.8, so
don't run the test suite in this job, because 'make test' takes rather
long [2], and it's already run five times in other jobs, so we
wouldn't get our time's worth.
[1] The Azure Pipelines builds have been using Ubuntu 16.04 images
from the start, so I belive they never caught 'for' loop initial
declarations.
[2] On Travis CI 'make test' alone would take about 9 minutes in this
new job (without running httpd, Subversion, and P4 tests). For
comparison, starting the job and building Git with GCC 4.8 takes
only about 2 minutes.
