SUMMARY="An interpreted, interactive, object-oriented programming language"
DESCRIPTION="Python is a programming language that lets you work more quickly \
and integrate your systems more effectively. You can learn to use Python and \
see almost immediate gains in productivity and lower maintenance costs.

Python runs on Windows, Linux/Unix, Mac OS X, and has been ported to the Java \
and .NET virtual machines.

Python is free to use, even for commercial products, because of its \
OSI-approved open source license."

# Some of the test will crash, invoking the crash dialog, and will hang waiting for
# user's interaction. To avoid that, make sure to configure your system by adding
# the following lines in the file "~/config/settings/system/debug_server/settings":
##---
# executable_actions {
#	/sources/Python-3.*/python kill
# }
##---

# For some tests that purposefully crash, it would make sense to add support for
# crash-report suppression (as done for other platforms) on "tests/support/__init__,py"'s
# SuppressCrashReport class.
# But that needs support from Haiku's debug_server, as we can't change settings from
# the recipe's building environment at the moment (https://dev.haiku-os.org/ticket/10301)

# To see the available test-runs options:
# > hp -E python3.nn
# > LIBRARY_PATH=%A:/boot/system/lib python -m test --help
# or:
# > LD_PRELOAD=./libpython3.nn.so.1.0 python -m test --help
#
# To only execute a particular test (from the $sourceDir):
#
# > LD_PRELOAD=./libpython3.nn.so.1.0 python -m test test_datetime -W
#
# Beware that running tests that way can cause some tests to fail, while they work fine under
# "hp --test"'s chroot. (test_sysconfig.MakefileTests.test_parse_makefile, for example).
# Problem is "os.getcwd()" will return wrong data, causing some file operations to fail.

# 345 tests OK. 23 tests failed. 28 tests skipped.
