JGit can show a fake ref "capabilities^{}" to "git fetch" when it
does not advertise any refs, but "git fetch" was not prepared to
see such an advertisement. When the other side disconnects without
giving any ref advertisement, we used to say "there may not be a
repository at that URL", but we may have seen other advertisement
like "shallow" and ".have" in which case we definitely know that a
repository is there. The code to detect this case has also been
updated.

Each test run generates a "count" file in t/test-results
that stores the number of successful, failed, etc tests.
If you run "t1234-foo.sh", that file is named as
"t/test-results/t1234-foo-$$.count"
The addition of the PID there is serving no purpose, and
makes analysis of the count files harder.
The presence of the PID dates back to 2d84e9f (Modify
test-lib.sh to output stats to t/test-results/*,
2008-06-08), but no reasoning is given there. Looking at the
current code, we can see that other files we write to
test-results (like *.exit and *.out) do _not_ have the PID
included. So the presence of the PID does not meaningfully
allow one to store the results from multiple runs anyway.
Moreover, anybody wishing to read the *.count files to
aggregate results has to deal with the presence of multiple
files for a given test (and figure out which one is the most
recent based on their timestamps!). The only consumer of
these files is the aggregate.sh script, which arguably gets
this wrong. If a test is run multiple times, its counts will
appear multiple times in the total (I say arguably only
because the desired semantics aren't documented anywhere,
but I have trouble seeing how this behavior could be
useful).
So let's just drop the PID, which fixes aggregate.sh, and
will make new features based around the count files easier
to write.
Note that since the count-file may already exist (when
re-running a test), we also switch the "cat" from appending
to truncating. The use of append here was pointless in the
first place, as we expected to always write to a unique file.

Skip tests that are unrunnable on platforms without 64-bit long
to avoid unnecessary test failures.
* jk/tzoffset-fix:
t0006: skip "far in the future" test when unsigned long is not long enough
|
|
Git's source code refers to timestamps as unsigned longs. On 32-bit
platforms, as well as on Windows, unsigned long is not large enough
to capture dates that are "absurdly far in the future".
While we can fix this issue properly by replacing unsigned long with
a larger type, we want to be a bit more conservative and just skip
those tests on the maint track.

Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.
* jk/test-send-sh-x-trace-elsewhere:
test-lib: set BASH_XTRACEFD automatically
|
|
Passing "-x" to a test script enables the shell's "set -x"
tracing, which can help with tracking down the command that
is causing a failure. Unfortunately, it can also _cause_
failures in some tests that redirect the stderr of a shell
function. Inside the function the shell continues to
respect "set -x", and the trace output is collected along
with whatever stderr is generated normally by the function.
You can see an example of this by running:
./t0040-parse-options.sh -x -i
which will fail immediately in the first test, as it
expects:
test_must_fail some-cmd 2>output.err
to leave output.err empty (but with "-x" it has our trace
output).
Unfortunately there isn't a portable or scalable solution to
this. We could teach test_must_fail to disable "set -x", but
that doesn't help any of the other functions or subshells.
However, we can work around it by pointing the "set -x"
output to our descriptor 4, which always points to the
original stderr of the test script. Unfortunately this only
works for bash, but it's better than nothing (and other
shells will just ignore the BASH_XTRACEFD variable).
The patch itself is a simple one-liner, but note the caveats
in the accompanying comments.
Automatic tests for our "-x" option may be a bit too meta
(and a pain, because they are bash-specific), but I did
confirm that it works correctly both with regular "-x" and
with "--verbose-only=1". This works because the latter flips
"set -x" off and on for particular tests (if it didn't, we
would get tracing for all tests, as going to descriptor 4
effectively circumvents the verbose flag).

On Windows, there is no SIGPIPE. A consequence of this is that the
upstream process of a pipe does not notice the death of the downstream
process until the pipe buffer is full and writing more data returns an
error. This behavior is the reason for an annoying delay during the
execution of t7610-mergetool.sh: There are a number of test cases where
'yes' is invoked upstream. Since the utility is basically an endless
loop it runs, on Windows, until the pipe buffer is full. This does take
a few seconds.
The test suite has its own implementation of 'yes'. Modify it to produce
only a limited amount of output that is sufficient for the test suite.
The amount chosen should be sufficiently high for any test case, assuming
that future test cases will not exaggerate their demands of input from
an upstream 'yes' invocation.

MSYS2 (the POSIX emulation layer used by Git for Windows' Bash) actually
has a working mkfifo. The only problem is that it is only emulating
named pipes through the MSYS2 runtime; The Win32 API has no idea about
named pipes, hence the Git executable cannot access those pipes either.
The symptom is that Git fails with a '<name>: No such file or directory'
because MSYS2 emulates named pipes through special-crafted '.lnk' files.
The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test on Windows.
This lets t4056-diff-order.sh, t9010-svn-fe.sh and t9300-fast-import.sh
pass.

Running tests with the "-x" option to make them verbose had some
unpleasant interactions with other features of the test suite.
* jk/test-with-x:
test-lib: disable trace when test is not verbose
test-lib: turn off "-x" tracing during chain-lint check
|
|
The "-x" test-script option turns on the shell's "-x"
tracing, which can help show why a particular test is
failing. Unfortunately, this can create false negatives in
some tests if they invoke a shell function with its stderr
redirected. t5512.10 is such a test, as it does:
test_must_fail git ls-remote refs*master >actual 2>&1 &&
test_cmp exp actual
The "actual" file gets the "-x" trace for the test_must_fail
function, which prevents it from matching the expected
output.
There's no way to avoid this without managing the
trace flag inside each sub-function, which isn't really a
workable solution. But unless you specifically care about
t5512.10, we can work around it by enabling tracing only for
the specific tests we want.
You can already do:
./t5512-ls-remote.sh -x --verbose-only=16
to see the trace only for a specific test. But that doesn't
_disable_ the tracing in the other tests; it just sends it
to /dev/null. However, there's no point in generating a
trace that the user won't see, so we can simply disable
tracing whenever it doesn't have a matching verbose flag.
The normal case of just "./t5512-ls-remote.sh -x" stays the
same, as "-x" already implies "--verbose" (and
"--verbose-only" overrides "--verbose", which is why this
works at all). And for our test, we need only check
$verbose, as maybe_setup_verbose will have already
set that flag based on the $verbose_only list).

Now that GIT_TEST_CHAIN_LINT is on by default, running:
./t0000-basic.sh -x --verbose-only=1
starts with:
expecting success:
find .git/objects -type f -print >should-be-empty &&
test_line_count = 0 should-be-empty
+ exit 117
error: last command exited with $?=117
+ find .git/objects -type f -print
+ test_line_count = 0 should-be-empty
+ test 3 != 3
+ wc -l
+ test 0 = 0
ok 1 - .git/objects should be empty after git init in an empty repo
This is confusing, as the "exit 117" line and the error line
(which is printed in red, no less!) are not part of the test
at all, but are rather in the separate chain-lint test_eval.
Let's unset the "trace" variable when eval-ing the chain
lint check, which avoids this.
Note that we cannot just do a one-shot variable like:
trace= test_eval ...
as the behavior of one-shot variables for function calls
is not portable.

If tput needs ~/.terminfo for the current $TERM, then tput will
succeed before HOME is changed to $TRASH_DIRECTORY (causing color to
be set to 't') but fail afterward.
One possible way to fix this is to treat HOME like TERM: back up the
original value and temporarily restore it before say_color() runs
tput.
Instead, pre-compute and save the color control sequences before
changing either TERM or HOME. Use the saved control sequences in
say_color() rather than call tput each time. This avoids the need to
back up and restore the TERM and HOME variables, and it avoids the
overhead of a subshell and two invocations of tput per call to
say_color().

There are two issues with that commit:
* It is buggy. In pseudocode, it is doing:
color is set || TERM != dumb && color works && color=t
when it should be doing:
color is set || { TERM != dumb && color works && color=t }
* It unnecessarily disables color when tput needs to read

It's easy to miss an "&&"-chain in a test script, like:
test_expect_success 'check something important' '
cmd1 &&
cmd2
cmd3
'
The test harness will notice if cmd3 fails, but a failure of
cmd1 or cmd2 will go unnoticed, as their exit status is lost
after cmd3 runs.
The toy example above is easy to spot because the "cmds" are
all the same length, but real code is much more complicated.
It's also difficult to detect these situations by statically
analyzing the shell code with regexps (like the
check-non-portable-shell script does); there's too much
context required to know whether a &&-chain is appropriate
on a given line or not.
This patch instead lets the shell check each test by
sticking a command with a specific and unusual return code
at the top of each test, like:
(exit 117) &&
cmd1 &&
cmd2
cmd3
In a well-formed test, the non-zero exit from the first
command prevents any of the rest from being run, and the
test's exit code is 117. In a bad test (like the one above),
the 117 is lost, and cmd3 is run.
When we encounter a failure of this check, we abort the test
script entirely. For one thing, we have no clue which subset
of the commands in the test snippet were actually run.
Running further tests would be pointless, because we're now
in an unknown state. And two, this is not a "test failure"
in the traditional sense. The test script is buggy, not the
code it is testing. We should be able to fix these problems
in the script once, and not have them come back later as a
regression in git's code.
After checking a test snippet for --chain-lint, we do still
run the test itself. We could actually have a pure-lint
mode which just checks each test, but there are a few
reasons not to. One, because the tests are executing
arbitrary code, which could impact the later environment
(e.g., that could impact which set of tests we run at all).
And two, because a pure-lint mode would still be expensive
to run, because a significant amount of code runs outside of
the test_expect_* blocks. Instead, this option is designed
to be used as part of a normal test suite run, where it adds
very little overhead.
Turning on this option detects quite a few problems in
existing tests, which will be fixed in subsequent patches.
However, there are a number of places it cannot reach:
- it cannot find a failure to break out of loops on error,
like:
cmd1 &&
for i in a b c; do
cmd2 $i
done &&
cmd3
which will not notice failures of "cmd2 a" or "cmd b"
- it cannot find a missing &&-chain inside a block or
subfunction, like:
foo () {
cmd1
cmd2
}
foo &&
bar
which will not notice a failure of cmd1.
- it only checks tests that you run; every platform will
have some tests skipped due to missing prequisites,
so it's impossible to say from one run that the test
suite is free of broken &&-chains. However, all tests get
run by _somebody_, so eventually we will notice problems.
- it does not operate on test_when_finished or prerequisite
blocks. It could, but these tends to be much shorter and
less of a problem, so I punted on them in this patch.

If you run a test script like:
GIT_TRACE=1 ./t0061-run-command.sh
you may get test failures, because some tests capture and
check the stderr output from git commands (and with
GIT_TRACE set to 1, the trace output will be included
there).
When we see GIT_TRACE set like this, we print a warning to
the user. However, we can do even better than that by just
pointing it to descriptor 4, which all tests leave connected
to the test script's stderr. That's likely what the user
intended (and any scripts that do want to see GIT_TRACE
output will set GIT_TRACE themselves).
Not only does this avoid false negatives in the tests, but
it means the user will actually see trace output for git
calls that redirect their stderr (whereas before, it was
sometimes confusingly buried in a file).

Right now if a test script receives SIGINT (e.g., because a
test was hanging and the user hit ^C), the shell exits
immediately. This can be annoying if the test script did any
global setup, like starting apache or git-daemon, as it will
not have an opportunity to clean up after itself. A
subsequent run of the test won't be able to start its own
daemon, and will either fail or skip the tests.
Instead, let's trap SIGINT to make sure we do a clean
shutdown, and just chain it to a normal exit (which will
trigger any cleanup).

What we wanted out of the SANITY precondition is that the filesystem
behaves sensibly with permission bits settings.
- You should not be able to remove a file in a read-only directory,
- You should not be able to tell if a file in a directory exists if
the directory lacks read or execute permission bits.
We used to cheat by approximating that condition with "is the /
writable?" test and/or "are we running as root?" test. Neither test
is sufficient or appropriate in environments like Cygwin.

The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).
Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.
We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS. Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:
1. we know we are root
2. we know we are not root
3. we could not tell, because `id` was not available
We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

If ncurses needs ~/.terminfo for the current $TERM, then tput will
succeed before changing HOME to $TRASH_DIRECTORY but fail afterward.
Move the tests that determine whether there is color support after
changing HOME so that color=t is set if and only if tput would succeed
when say_color() is run.
Note that color=t is now set after --no-color is processed, so the
condition to set color=t has changed: it is now set only if
color has not already been set to the empty string by --no-color.
This disables color support for those that need ~/.terminfo for
their TERM, but it's better than filling the screen with:
tput: unknown terminal "custom-terminal-name-here"
An alternative would be to symlink or copy the user's terminfo
database into $TRASH_DIRECTORY, but this is tricky due to the lack of
a standard name for the terminfo database (for example, instead of a
~/.terminfo directory, NetBSD uses a ~/.terminfo.cdb database file).
