Sporadic interactive test failures

[aryler]

The interactive tests will fail sometimes.
This seems to have started with 8.2.

$ cd /path/to/jim/tests
$ while true; do jimsh interactive.test; done

[aryler]

Looks like terminal control characters at the end.

[msteveb]

What platform are you on? I can't reproduce this

[aryler]

I can reliably reproduce on OpenBSD-current, i386 (32 bit) and amd64 (64 bit).
Problem goes away if I configure with --disable-lineedit.

[msteveb]

OK,thanks. I don't have openbsd available right now but when I do I'll try to reproduce

[sgbeal]

While trying to reproduce this on an OpenBSD VM i notice that a fresh checkout of jimtcl fails to build because of that braindead linker output OpenBSD generates:

$ ./configure --prefix=$HOME
No installed jimsh or tclsh, building local bootstrap jimsh0
./configure[4]: ld: warning: jimsh0.c(/tmp/stephan/jimsh0-815d7e.o:(Jim_FormatString)): warning: sprintf() is often misused, please use snprintf()

/home/stephan/src/jimtcl/jimsh0: not found

Re-running configure a second time works - it's only the extra output which confuses it.

That was already resolved in upstream autosetup.

[sgbeal]

fwiw this is reproducible on an OpenBSD 7.6 vm:

What version? Is this master (3a2cfdf). Should be fixed there.

[sgbeal]

What version? Is this master (3a2cfdf). Should be fixed there.

It was a freshly-cloned copy of [3a2cfdf].

It repros consistently here with:

$ make distclean
...

$ ./configure
... works as expected

$ uname -a
OpenBSD obvm.fritz.box 7.6 GENERIC.MP#338 amd64

[msteveb]

Thanks. I'll hopefully be able to fire up an openbsd vm soon and reproduce this.

[msteveb]

OK, two separate issues here. The configure problem is because we don't have the redirection order correct in autosetup-find-tclsh

The occasional test failures are do do with how linenoise waits for the window size response to be returned. It has some fixed timeouts that don't seem to work well on OpenBSD (at least in a VM). I'll have to investigate further to see how to make this more reliable.

[msteveb]

Because the child process is being controlled via pty pair, the window size is not available. Sometimes the first char is eaten by the code waiting for the window size response and then everything goes downhill from there.

[msteveb]

I've pushed some changes to branch openbsd-fix
Let me know if that resolves the issue for you

[aryler]

Thanks, that's quite a bit of work!
The original problem may be fixed but now this:
