[issue43659] AIX: test_curses crashes buildbot

2021-04-28 Thread Michael Felt 

Michael Felt  added the comment:

Dome some 'dumb' testing - and I hope this helps understand why it is failing:

With the the last two func() calls commented out, the function passes:

def test_output_string(self):
stdscr = self.stdscr
encoding = stdscr.encoding
# addstr()/insstr()
for func in [stdscr.addstr, stdscr.insstr]:
with self.subTest(func.__qualname__):
stdscr.move(0, 0)
func('abcd')
func(b'abcd')
s = 'à▒^▒ç▒^▒'
try:
func(s)
except UnicodeEncodeError:
self.assertRaises(UnicodeEncodeError, s.encode, encoding)
func('abcd', curses.A_BOLD)
# func(1, 2, 'abcd')
# func(2, 3, 'abcd', curses.A_BOLD)

Michael Felt  added the comment:

./python -m test -vuall -i test_output_string -i test_insert_delete test_curses 
2>test.err 1>test.out

returns four failures: see attached

'-i test_output_string' stops the crash

Serhiy Storchaka  added the comment:

Please also try to comment out the following line in test_output_string. Does 
it help?

s = '\u0661\u0662\u0663\u0664'
try:
func(s, 3)
except UnicodeEncodeError:
self.assertRaises(UnicodeEncodeError, s.encode, encoding)

2021-03-30 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

Thank you. I see that 7 tests are failed (test_background, test_color_attrs, 
test_color_content, test_getch, test_getstr, test_init_pair, 
test_insert_delete) and test_output_string perhaps crashes.

Could you please run tests with test_insert_delete skipped (option -i 
test_insert_delete or just skip in code)? If it crashes on other tests, skip 
them as well.

Michael Felt  added the comment:

my default TERM=xterm

I'll also use 'ansi'

The filenames will be ${TERM}.err and ${TERM}.out

for TERM in xterm ansi; do
./python -m test -vuall test_curses 2>${TERM}.err >${TERM}.out
done

After TERM=ansi - my terminal is in raw mode (i.e.,
$ stty sane ^J

needed).

2021-03-29 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

Minor correction. update_lines_cols() is not provided by the underlying curses 
library, it is a helper defined in Python wrapper. But it is optional, snd 
skipping test is the correct solution. Thank you.

As for the core dump, could you please run the test in verbose mode with 
redirected stdout and stderr and show the result?

./python -m test -vuall test_curses 2>test.err >test.out

What is the default value of TERM? Does the result differ if set TERM=xterm?

[issue43659] AIX: test_curses crashes buildbot

2021-03-29 Thread Michael Felt 


New submission from Michael Felt :

Since issue42789 the AIX bot's have crashed - to the extent that the bot's did 
not even return results.

Part of this has been resolved, for now, by using:

$ export TERM=unknown
$ buildbot start buildarea

However, the test still crash because AIX default libcurses.a does not include 
support for update_lines_cols().

This patch should allow test_curses.py to pass in the buildbot.

When run from command-line as:

$ TERM=unknown ./python Lib/test/test_curses.py
.ss..ss
--
Ran 71 tests in 0.121s

OK (skipped=64)
aixtools@cpython2:[/home/aixtools/py3a-10.0]

(When TERM is defined - a core dump still occurs - that will be a new issue and 
a new PR).
