Unfortunately, this patch doesn't seem to work. Maybe it interferes with condition handlers? At any rate, after I insert it into script-support.lisp I now get two new test failures in package-inferred-system-test.script and test-defsystem-depends-on.script. I get a message that

Top level in: #<process TOP-LEVEL>.
ECL unexpectedly landed in the top level prompt. Script aborted.
Using ecl, package-inferred-system-test.script failed

...and one like it for the other test. So there were some failures there that were correctly caught before that are no longer.

Yes, the Ubuntu package definitely should be updated to version 16.1.3
which fixes the issue. But the ECL developers can't run to the
maintainer of the ECL package of every linux distribution and ask them
to upgrade their package each time they make a new release. And even if
they could, the package maintainers probably wouldn't do it, since some
other package might depend on an older ECL version.

For the moment, the best solution I can offer you for your problem is a
dirty hack to prevent older ECL versions from entering the interactive REPL:

diff --git a/test/script-support.lisp b/test/script-support.lisp
index 86b6c1f2..7f72488a 100644

Of course since this is only a workaround to prevent the tests from
stopping, the tests in which ECL would stop without the workaround will
fail on ECL versions <= 16.1.2.

This is most likely a bug in ECL. I recommend trying out a newer version
of ecl (16.1.3 or the current develop branch from the git repository).

I see your point, but have two comments:

1.

If this really /is/ an ECL bug, then shouldn't the Ubuntu package be
updated and fixed? ASDF is supposed to work on the ECL that users
will have, not only on the one that developers have.

2.

I don't see a way to get a new ECL except by pulling from Gitlab and
building. I do not have the time to run around building all
available lisp implementations from source (and, again, ASDF should
work on the versions of the implementations that users actually
have, which means the ones provided by the packaging systems on the
platforms). I build only SBCL, because that's an implementation I
build anyway, for my work needs. Faré had the energy to play with
all the different implementations in a substantial way, but I do not.

So if the released version of an implementation is broken, I will simply
regard that implementation as broken. If the /released version/ of an
implementation is broken for long enough (I'm looking at you, clisp), it
will become unsupported by ASDF. Unsupported means "patches will be
accepted, but I will no longer run the tests, and test failure on an
unsupported implementation will not be a reason to hold up an ASDF release."

Note that at the moment /all/ implementations are essentially
unsupported on Windows, since I have lost my Windows VM, and even if I
got it back, I would have no way to develop on Windows. If you are a
Windows user and this bothers you, I would be happy to support you in
setting up a test environment, and even more happy to help you learn to
patch ASDF. But even someone who doesn't want to patch ASDF, but who
would be willing to run the test suite (or help figure out how it could
be run through, e.g., Travis), would be a great help.

I'm experimenting with your changes now but, for some reason that I
don't understand, when I run the tests as |make l=ecl|
interactively on
Ubuntu (using the Ubuntu ECL package |16.1.2-3|), signals are
throwing
me into the interactive debugger, instead of being caught. I have no
idea why this started happening, because I used to be able to
run ECL
successfully, and I don't believe I have changed the package
(although
Ubuntu might have upgraded it).

Actually /usr/bin/ecl is crashing with SIGABRT when running
programs,
apparently, on my Ubuntu box. (|SIGABRT in si_run_program()|).
I'll try
uninstalling and reinstalling ECL in the hopes that fixes this, but
unless I get some help, I will not be able to continue testing
ASDF on
ECL on Linux.

No, I don't think so. The sockets module has been part of ECL since
version 0.9f from 2005. Please note, that this test can fail
anyway if
ECL is built without support for the respective module (be it :rt or
:sockets). The change only prevents it from failing on a default
build
configuration.

Thank you very much for these, Marius. I will look into fixing them
directly. One question - do I need to check for ECL version
number when
requiring sockets in the test? I.e., to I need to test with |:rt| in
older versions and |:sockets| in newer? Or will |:sockets| work
in older
versions of ECL, as well?

Best,

Harmless in the sense that ECL doesn't crash or throw me in the
interactive debugger. Besides, the test failures seem to be easily
fixed. The test-require.script test fails because it tries to
require
the :rt module which is deprecated on the develop branch and no
longer
build by default. A simple fix is to use the :sockets module
instead:

The test-program.script test seems to fail to include uiop

I can't reproduce this, for me the tests run fine without

(test-program.script and test-require.script).

No test failure is harmless. The test-program.script failure is what
Robert saw, that I can reproduce. I didn't reproduce a failure with
test-require. I had more problems with ECL from the develop branch,
but maybe it was a bad idea to use the develop branch.
