py/objexcept: Support errno attribute on OSError exceptions. 2021-04-23T12:03:46+00:00 Damien George 2021-04-20T07:11:13+00:00 3c4bfd1dec28ffbefc6379dedeaa24feaa2ef373 This commit adds the errno attribute to exceptions, so code can retrieve errno codes from an OSError using exc.errno. The implementation here simply lets `errno` (and the existing `value`) attributes work on any exception instance (they both alias args[0]). This is for efficiency and to keep code size down. The pros and cons of this are: Pros: - more compatible with CPython, less difference to document and learn - OSError().errno will correctly return None, whereas the current way of doing it via OSError().args[0] will raise an IndexError - it reduces code size on most bare-metal ports (because they already have the errno qstr) - for Python code that uses exc.errno the generated bytecode is 2 bytes smaller and more efficient to execute (compared with exc.args[0]); so bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute, and bytecode that is frozen saves 2 bytes flash/ROM for each use - it's easier/shorter to type, and saves 2 bytes of space in .py files that use it (for each use) Cons: - increases code size by 4-8 bytes on minimal ports that don't already have the `errno` qstr - all exceptions now have .errno and .value attributes (a cpydiff test is added to address this) See also #2407.

This commit adds the errno attribute to exceptions, so code can retrieve
errno codes from an OSError using exc.errno.

The implementation here simply lets `errno` (and the existing `value`)
attributes work on any exception instance (they both alias args[0]).  This
is for efficiency and to keep code size down.  The pros and cons of this
are:

Pros:
- more compatible with CPython, less difference to document and learn
- OSError().errno will correctly return None, whereas the current way of
  doing it via OSError().args[0] will raise an IndexError
- it reduces code size on most bare-metal ports (because they already have
  the errno qstr)
- for Python code that uses exc.errno the generated bytecode is 2 bytes
  smaller and more efficient to execute (compared with exc.args[0]); so
  bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute,
  and bytecode that is frozen saves 2 bytes flash/ROM for each use
- it's easier/shorter to type, and saves 2 bytes of space in .py files that
  use it (for each use)

Cons:
- increases code size by 4-8 bytes on minimal ports that don't already have
  the `errno` qstr
- all exceptions now have .errno and .value attributes (a cpydiff test is
  added to address this)

unix: Improve command line argument processing. 2021-04-07T02:41:25+00:00 stijn 2021-04-06T18:40:31+00:00 a66286f3a0f24985cae2648102e51de64b8a1871 Per CPython everything which comes after the command, module or file argument is not an option for the interpreter itself. Hence the processing of options should stop when encountering those, and the remainder be passed as sys.argv. Note the latter was already the case for a module or file but not for a command. This fixes issues like 'micropython myfile.py -h' showing the help and exiting instead of passing '-h' as sys.argv[1], likewise for '-X <something>' being treated as a special option no matter where it occurs on the command line.
