This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.
Note that t5541 uses the reversed `master` name: `retsam`. We replace it
by the equivalent for `main`: `niam`.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\

Use 'test_atexit' to run cleanup commands to stop httpd at the end of
the test script or upon interrupt or failure, as it is shorter,
simpler, and more robust than registering such cleanup commands in the
trap on EXIT in the test scripts.

httpd tests saw occasional breakage due to the way its access log
gets inspected by the tests, which has been updated to make them
less flaky.
* sg/httpd-test-unflake:
t/lib-httpd: avoid occasional failures when checking access.log
t/lib-httpd: add the strip_access_log() helper function
t5541: clean up truncating access log
|

The last test of 't5561-http-backend.sh', 'server request log matches
test results' may fail occasionally, because the order of entries in
Apache's access log doesn't match the order of requests sent in the
previous tests, although all the right requests are there. I saw it
fail on Travis CI five times in the span of about half a year, when
the order of two subsequent requests was flipped, and could trigger
the failure with a modified Git. However, I was unable to trigger it
with stock Git on my machine. Three tests in
't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check
requests in the log the same way, so they might be prone to a similar
occasional failure as well.
When a test sends a HTTP request, it can continue execution after
'git-http-backend' fulfilled that request, but Apache writes the
corresponding access log entry only after 'git-http-backend' exited.
Some time inevitably passes between fulfilling the request and writing
the log entry, and, under unfavourable circumstances, enough time
might pass for the subsequent request to be sent and fulfilled by a
different Apache thread or process, and then Apache writes access log
entries racily.
This effect can be exacerbated by adding a bit of variable delay after
the request is fulfilled but before 'git-http-backend' exits, e.g.
like this:
diff --git a/http-backend.c b/http-backend.c
index f3dc218b2..bbf4c125b 100644
--- a/http-backend.c
+++ b/http-backend.c
@@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv)
max_request_buffer);
cmd->imp(&hdr, cmd_arg);
+ if (getpid() % 2)
+ sleep(1);
return 0;
}
This delay considerably increases the chances of log entries being
written out of order, and in turn makes t5561's last test fail almost
every time. Alas, it doesn't seem to be enough to trigger a similar
failure in t5541 and t5551.
So, since we can't just rely on the order of access log entries always
corresponding the order of requests, make checking the access log more
deterministic by sorting (simply lexicographically) both the stripped
access log entries and the expected entries before the comparison with
'test_cmp'. This way the order of log entries won't matter and
occasional out-of-order entries won't trigger a test failure, but the
comparison will still notice any unexpected or missing log entries.
OTOH, this sorting will make it harder to identify from which test an
unexpected log entry came from or which test's request went missing.
Therefore, in case of an error include the comparison of the unsorted
log enries in the test output as well.
And since all this should be performed in four tests in three test
scripts, put this into a new helper function 'check_access_log' in
't/lib-httpd.sh'.

Four tests in three httpd-related test scripts check the contents of
Apache's 'access.log', and they all do so by running 'sed' with the
exact same script consisting of four s/// commands to strip
uninteresting log fields and to vertically align the requested URLs.
Extract this into a common helper function 'strip_access_log' in
'lib-httpd.sh', and use it in all of those tests.

It's possible to have libcurl installed but not the curl
command-line utility. The latter is not generally needed for
Git's http support, but we use it in t5561 for basic tests
of http-backend's functionality. Let's detect when it's
missing and skip this test.
Note that we can't mark the individual tests with the CURL
prerequisite. They're in a shared t556x_common that uses the
GET and POST functions as a level of indirection, and it's
only our implementations of those functions in t5561 that
requires curl. It's not a problem, though, as literally
every test in the script would depend on the prerequisite
anyway.

For a normal test run, stderr is already redirected to
/dev/null by the test suite. When used with "-v",
suppressing stderr is actively harmful, as it may hide the
reason for curl failing.

A test script for the HTTP service had a timing dependent bug,
which was fixed.
* sb/http-flaky-test-fix:
t5561: get rid of racy appending to logfile
|
|
The definition of log_div() appended information to the web server's
logfile to make the test more readable. However, log_div() was called
right after a request is served (which is done by git-http-backend);
the web server waits for the git-http-backend process to exit before
it writes to the log file. When the duration between serving a request
and exiting was long, the log_div() output was written before the last
request's log, and the test failed. (This duration could become
especially long for PROFILE=GEN builds.)
To get rid of this behavior, we should not change the logfile at all.
This commit removes log_div() and its calls. The additional information
is kept in the test (for readability reasons) but filtered out before
comparing it to the actual logfile.

If we built git without curl, we can't actually test against
an http server. In fact, all of the test scripts which
include lib-httpd.sh already perform this check, with one
exception: t5540. For those scripts, this is a noop, and for
t5540, this is a bugfix (it used to fail when built with
NO_CURL, though it could go unnoticed if you had a stale
git-remote-https in your build directory).

We set the default apache port for each of the httpd tests
to the 4-digit test number of the test script. We want these
to remain unique so that the tests do not conflict with each
other when run in parallel.
Instead of doing it manually in each test script, let's just
set it from the test name at run time. This is simpler, and
is one less thing to be updated when test scripts are
renamed (e.g., when being re-rolled or when conflicting
after being merged with another topic).
Incidentally, this fixes a case where t5537 and t5538 used
the same port number (5537), and could conflict with each
other when run in parallel.

SKIP messages are now part of the TAP plan. A TAP harness now knows
why a particular test was skipped and can report that information. The
non-TAP harness built into Git's test-lib did nothing special with
these messages, and is unaffected by these changes.
