2013-06-05Make all steps ofterm_to_binary work in chunks and yieldPatrik Nyblom
Rewrite and extend of Happi's initial work Extra_root to process structure to enable GC of state - Changed the process structure to point to a separate struct, the struct also contains a destructor function to allow for proper cleanup. Rewrote encode_size_struct and enc_term to have internal versions with reduction counters which will result in interrupt for later restart when the counter reaches zero - removed the EWA_STACK from Happis version and directly save the ESTACK's and WSTACK's in the above mentioned struct (or array thereof) that are pointed out from the process structure. The destructor will take care of the deallocation in case of process death. Added ESTACK and WSTACK macros to save and restore stack and to change allocator, which makes the previously mentioned stack-save work. Rewrote enc_term to not store pointers on the stack, and use one WSTACK for commands etc and another ESTACK for Eterms - Slightly different than Happis version to make halfword code simpler. Rewrote encode_size_struct2 so that it does not store pointers on the stack, also switched to ESTACK instead of WSTACK, this also handles halfword correctly. Added interfaces for chunkwise compression, that are used from term_to_binary/2 when the compressed option is given.

2012-08-14Make get/putenv and erlexec understand UnicodePatrik Nyblom
Putenv and getenv needs to convert to the proper environment strings in Unicode depending on platform and user settings for filename encoding. Also erlexec needs to pass environment strings in an appropriate way for kernel to pick up. All environment strings on the command line, as well as home directory, is now passed in UTF8 on windows and in whatever encoding you have on Unix, kernel tries to convert all parameters and environments from UTF8 before making strings.
2012-06-25Don't go to single-scheduler mode when managing breakpointsBjörn Gustavsson
Calls to erlang:set_trace_pattern/3 will no longer block all other schedulers. We will still go to single-scheduler mode when new code is loaded for a module that is traced, or when loading code when there is a default trace pattern set. That is not impossible to fix, but that requires much closer cooperation between tracing BIFs and the loader BIFs.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.
