The bytes constructor would then attempt to zero out all this memory, thinking it had allocated 2^32-1 bytes. py/objstr: Make empty bytes object have a null-terminating byte. 2017-10-04T06:59:22+00:00 Damien George damien.p.george@gmail.com 2017-10-04T06:59:22+00:00 urn:sha1:dfa563c71fead671931e91b786cd649eed517f92 Because a lot of string processing functions assume there is a null terminating byte, so they can work in an efficient way. Fixes issue #3334. tests: Add tests to exercise lexer; and some more complex number tests. 2015-04-04T22:16:22+00:00 Damien George damien.p.george@gmail.com 2015-04-04T22:16:22+00:00 urn:sha1:97abe22963af5b62656cef5a46c195215f75f7d2 tests: Add some more tests for bytes, bignum, string and ujson. 2015-03-14T21:20:58+00:00 Damien George damien.p.george@gmail.com 2015-03-14T21:20:58+00:00 urn:sha1:26a9975fba2bbd8875f2671495003b9bdcb8d8b2 tests: Add testcase for bytes() on values in range 128-255. 2015-01-28T20:29:51+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-01-28T20:29:51+00:00 urn:sha1:57aebe171459fd599f8d430c1ea1660ed307360c tests: Fix uctypes tests to run on 64bit arch; enable more native tests. 2014-09-23T14:15:45+00:00 Damien George damien.p.george@gmail.com 2014-09-23T12:09:26+00:00 urn:sha1:96e20c600f6498c403445956077f85dd2fb548aa objstr: Make sure that bytes are indexed as bytes, not as unicode. 2014-08-11T19:38:00+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-08-11T19:36:38+00:00 urn:sha1:9749b2fb0d6c4ff65c7395e09028102c9508b34a Fixes #795. py: Make 'bytes' be a proper type, support standard constructor args. 2014-03-21T22:07:04+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-03-21T21:46:59+00:00 urn:sha1:1ecea7c7539e73f105fef25da8a3bde7783da755 Add basic implementation of bytes type, piggybacking on str. 2014-01-24T20:56:26+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-01-24T20:50:40+00:00 urn:sha1:91fb1c9b13021e90fa2f8c2105c135fc14ac71db This reuses as much str implementation as possible, from this we can make them more separate as needed.
