all: Rename "sys" module to "usys". This is consistent with the other 'micro' modules and allows implementing additional features in Python via e.g. micropython-lib's sys. Note this is a breaking change (not backwards compatible) for ports which do not enable weak links, as "import sys" must now be replaced with "import usys". 2020-06-18 10:19:14 +01:00			`try:`

tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting. 2020-03-23 02:26:08 +00:00
modsys: Add basic sys.exc_info() implementation. The implementation is very basic and non-compliant and provided solely for CPython compatibility. The function itself is bad Python2 heritage, its usage is discouraged. 2015-04-25 01:17:41 +01:00			`try:`
			`sys.exc_info`
			`except:`

tests: Convert remaining "sys.exit()" to "raise SystemExit". 2017-06-10 18:14:16 +01:00			`raise SystemExit`

tests: Modify tests that print repr of an exception with 1 arg. In Python 3.7 the behaviour of repr() of an exception with one argument changed: it no longer prints a trailing comma in the argument list. See https://bugs.python.org/issue30399 This patch modifies tests that rely on this behaviour to not rely on it. And the python34.py test is updated to include a test for this behaviour with a .exp file. 2018-08-17 06:46:04 +01:00			`raise ValueError("value", 123)`

vm: On exiting except block, clear sys.exc_info() value. This doesn't handle case fo enclosed except blocks, but once again, sys.exc_info() support is a workaround for software which uses it instead of properly catching exceptions via variable in except clause. 2015-04-25 23:20:49 +01:00			`# Outside except block, sys.exc_info() should be back to None's`
