[PATCH 00/11] testsuite refurbishment

[Jon Turney]

Fix testsuite Makefile/configure, so I have some idea what it's supposed to
be doing, prior to cleanup and Automake-ification.

> $ make check
[...]
> # of expected passes            253
> # of unexpected failures        23
> # of unexpected successes       1
> # of expected failures          7
 
Future work:
- Investigate and fix failing tests
- Tests are re-compiled every time they are run
- No parallelization of tests

For ease of reviewing, this patch series doesn't contain changes to
generated files which would be made by an autoreconf.

Jon Turney (11):
  Add testsuite directory to autogen.sh
  Always configure in testsuite subdirectory
  Add rule to testsuite Makefile to regenerate it when needed
  Avoid 'Makefile.in seems to ignore the --datarootdir setting' warning
  Move adding libltp to VPATH after Makefile.common
  Define target_builddir autoconf and Makefile variables
  Detect and use MinGW compilers for testsuite wrappers
  Use absolute path to libltp includes
  Check exit code of a test, rather than stdout
  Set PATH for tests to pick up cygwin0.dll
  Ensure temporary directory used by tests exists

[PATCH 02/11] Always configure in testsuite subdirectory

Doing this properly using AC_CONFIG_SUBDIRS is necessary to get the
correct paths in flags given to the compiler specified in CC/CXX.

[PATCH 06/11] Define target_builddir autoconf and Makefile variables

[Jon Turney]

This now required as cygwin_build is defined in terms of
target_builddir.

(Note that in other subdirectories, the autoconf variable
target_builddir is AC_SUBST-ed as a side-effect of using a macro from
winsup/acinclude.m4, which is perhaps less than ideal)

[PATCH 11/11] Ensure temporary directory used by tests exists

[Jon Turney]

By default, libltp tests will create temporary files in a subdirectory
of /tmp, which will (nowadays) be located relative to the test DLL (by
assuming that it is in /bin).  This will evaluate to the directory
$target_builddir/winsup/tmp, which doesn't exist.

The location used for these temporary files can be explicitly controlled
by setting the TDIRECTORY env var.  Arrange to set that env var to the
/cygdrive path of a tmp subdirectory of the build directory.

Unfortunately, libltp doesn't clean the temporary directory if
TDIRECTORY is set, and some tests assume they are started in a clean
directory, so we need to do that in tcl.

This isn't right if the cygdrive prefix is not 'cygdrive'.  Maybe use 
'proc/cygdrive' instead of 'cygdrive'?

That's how I originally had it.  Unfortunately, test ltp/symlink01 
relies on the test directory being specified as a canonicalized pathname 
(i.e. is the same after realpath()).

Since there's no /etc/fstab in the the filesystem relative to the test 
DLL, I think it should always be using the default cygdrive prefix?

But there's a mkdir command that seems to be run in the context of the user 
running 'make check'.  If the cygdrive prefix is not 'cygdrive', 'make check' 
fails as follows:

ERROR: tcl error sourcing 
/home/kbrown/src/cygdll/newlib-cygwin/winsup/testsuite/winsup.api/winsup.exp.
ERROR: can't create directory "/cygdrive": permission denied
     while executing
"file mkdir $tmpdir/$base"

Unfortunately, cygpath has limitations dealing with paths with trailing
component symlinks, and readlink has limitations dealing with paths with leading
symlinks, while realpath overcomes those limitations and has other options to
deal with symlink issues:

$ cygpath ~/RPi
/home/bwi/RPi
$ readlink ~/RPi
Documents/Info/RPi
$ realpath ~/RPi
/.../Documents/Info/RPi

Could you not use:
tmpdir = $(shell realpath $(cygpath -aU $(objdir)/testsuite/tmp/))
or:
tmpdir = $(shell cygpath -aU $(objdir)/testsuite/tmp/ | xargs realpath)
otherwise:
	pfx=$(realpath /proc/cygdrive)
to get the drive prefix and use that directly when appropriate?

That fixes it, thanks.  I get

                 === winsup Summary ===

# of expected passes            253
# of unexpected failures        23
# of unexpected successes       1
# of expected failures          7

Is that consistent with what you see?  I especially like the unexpected success. 
  That made my day.

I think it's great that you're resurrecting the test suite.  Thanks for doing that.

I have my own suite of fifo tests that I run every time I change something, and 
it's very tedious to do it by hand.  Currently almost all of them are set up to 
run interactively.  For example, they might involve typing "echo blah > 
/tmp/myfifo" in one terminal and checking for a response in a second terminal. 
I'll have to figure out how to make them run non-interactively.
