It turns out that in all conformant shells, "unset FOO" removes FOO
both from the shell's variables and from the exported environment.
(I've tested this on msys, opensolaris, linux, osx, and freebsd.)
And in nearly every shell I can find, "unset FOO; export FOO" does
the same as unset FOO... except in my FreeBSD VM, where the "export
FOO" sets the exported value of FOO equal to "". This broke test.sh
for us.
The fix is simple: remove the needless exports!
This required:
- Adding another WIN32 section in test.sh
- not running "touch /dev/null"
- calling WSAStartup in all the test binaries
- Fixing a dumb windows-only bug in test-time.c
Some systems have a version of /bin/sh whose builtin echo doesn't
support the -n option used in test/test.sh. /bin/echo, however,
usually does. This patch makes us use /bin/echo for echo -n whenever
it is present.
Also, our use of echo -n really only made sense when suppressing all
test output. Since test output isn't suppressed when logging to a
file, this pach makes us stop using echo -n when logging to a file.
By default, the test.sh script still suppresses the output of all the
tests it invokes. Now, however, you can have that output written to
a file specified in the TEST_OUTPUT_FILE shell variable.
Remove rtsig method, as discussed in July. It hasn't compiled for quite a while, and nobody has seemed to miss it much. Please let us know if this was a bad call. [Tracker issue 1826539].
