This is wasteful in RAM and not efficient. Now, these constants are parsed straight away in the parser and turned into objects. This allows constants with large numbers of digits (so addresses issue #1103) and takes us a step closer to #722. py: Protect mp_parse and mp_compile with nlr push/pop block. 2015-02-07T18:33:58+00:00 Damien George damien.p.george@gmail.com 2015-02-07T18:33:58+00:00 urn:sha1:0bfc7638baa4c5a4a2351364ab770a188dcab302 To enable parsing constants more efficiently, mp_parse should be allowed to raise an exception, and mp_compile can already raise a MemoryError. So these functions need to be protected by an nlr push/pop block. This patch adds that feature in all places. This allows to simplify how mp_parse and mp_compile are called: they now raise an exception if they have an error and so explicit checking is not needed anymore. py: Be more machine-portable with size of bit fields. 2015-01-24T23:12:58+00:00 Damien George damien.p.george@gmail.com 2015-01-24T23:12:58+00:00 urn:sha1:5c670acb1fdd04dcb9c220fee7cbeeb6b0c440e5 py, unix, stmhal: Allow to compile with -Wshadow. 2015-01-20T11:55:10+00:00 Damien George damien.p.george@gmail.com 2015-01-20T11:55:10+00:00 urn:sha1:50912e7f5dc579fd2917537046793dfa30decadf See issue #699. py, unix: Allow to compile with -Wsign-compare. 2015-01-16T17:47:07+00:00 Damien George damien.p.george@gmail.com 2015-01-16T17:47:07+00:00 urn:sha1:963a5a3e82ded7ee75adae72ae7cb14796fa150e See issue #699. py: Add "default" to switches to allow better code flow analysis. 2015-01-14T21:32:42+00:00 Damien George damien.p.george@gmail.com 2015-01-14T21:32:42+00:00 urn:sha1:d2d64f00fb7f1487c1fa21a456e003a801d7e711 This helps compiler produce smaller code.

With this patch, long string/bytes objects are never interned, and are referenced directly as constant objects within generated code using load_const_obj.
