This doesn't happen in verbose mode, because stdout isn't checked:

$ ./python -m test.regrtest test_gdb_sample
test_gdb_sample
test test_gdb_sample produced unexpected output:

[davidmalcolm]

Sorry about that.

"test_gdb_sample.py" is merely a sample script for use by "test_gdb.py" (see bpo-8032); it's not intended to do anything useful by itself (though it does need a "print" invocation, since test_gdb.py uses a breakpoint in PyObject_Print).

I would probably be simplest to rename it so it doesn't have a "test_" prefix.

How about "sample_for_test_gdb.py", or somesuch?

[pitrou]

I would probably be simplest to rename it so it doesn't have a "test_" prefix.

Indeed. Otherwise it gets caught and executed by regrtest as part of the
standard test suite.

How about "sample_for_test_gdb.py", or somesuch?

Shorter would be better :)
For example gdb_sample.py, gdb_fodder.py...

[davidmalcolm]

"gdb_sample.py" as a name works for me. I don't have commit rights to SVN so I can't perform the rename myself.

(Note that due to bpo-8279 the file isn't actually used at the moment by test_gdb.py so it should be safe to rename. I have a patch attached to that latter bug; I'll fix up the patch after that file is renamed).

Thank you, this is done in r79557.

[vstinner]

test_gdb.py refers to test_gdb_sample.py instead of gdb_sample.py. Attached patch fixes that.

But then I get new errors:

I tried with pydebug and without pydebug.

Oops, my last message (msg103435) was for bpo-8434, not this issue. Anyway, bpo-8434 is a duplicate of bpo-8279, it doesn't matter.
