2015-11-26erts: Reduce alloc_SUITE:rbtree runtime for valgrindSverker Eriksson
2015-11-26erts: Remove double free in efile_drvSverker Eriksson
That double free is probably very seldom invoked as the port is already gone leading to free_data being called instead of file_async_ready.
2015-11-26erts: Improve alloc_SUITE:migration testSverker Eriksson
In the quest to improve code coverage in cpool_fetch
2015-11-26erts: Pass free mem and build type to alloc_SUITE testsSverker Eriksson
2015-11-26erts: Fix snprintf in alloc_SUITE for windowsSverker Eriksson
2015-11-26erts: Workaround for strange crash on win64 in alloc_SUITE test codeSverker Eriksson
For some reason setjmp() crash when having jmp_buf heap allocated but works when stack allocated.
2015-11-26erts: Refactor alloc_SUITE to use NIFs instead of driversSverker Eriksson
2015-11-26erts: Add enif_getenvSverker Eriksson
to read OS environment variables in a safe and portable way.

2015-11-20erts: Fix maps decode in erlang:binary_to_term/1Björn-Egil Dahlberg
Decoding a term with a large (HAMT) map in an small (FLAT) map could cause a critical error if the external format was not produced by beam.

2015-11-18Use sharing preserving copy in enif_make_copyBjörn-Egil Dahlberg
2015-11-18Refactor sharing preserved copy flagsBjörn-Egil Dahlberg
The TMPBUF option is no longer needed due to is_literal test and NONE was only used for initial debugging. So we remove the entire option.

2015-11-17Add erlang:copy_literals/2 specBjörn-Egil Dahlberg
2015-11-17Add copy_literals testcaseBjörn-Egil Dahlberg
Repeatedly reload a literals module while sending the references literals around in a process ring. This will smoke test the non-copying literals message sending does not corrupt code unloading.
2015-11-17Do not use GCC extensions in copyBjörn-Egil Dahlberg
2015-11-17Use copy literal range check in message passing and purgingBjörn-Egil Dahlberg
2015-11-17Add BIF for setting internal copy literal rangeBjörn-Egil Dahlberg

2015-11-17Add support for HAMT maps in preserved copyBjörn-Egil Dahlberg
2015-11-17Fix Map preserved sharing copy implementationBjörn-Egil Dahlberg
The Map implementation has changed since initial preserved copy implementation.
2015-11-17Fix Halfword removalBjörn-Egil Dahlberg
Halfword is no longer present in the runtime system.
2015-11-17Fix internal stacksBjörn-Egil Dahlberg
The internal stacks has changed between releases.
2015-11-17Add support for maps in preserved copyNikolaos S. Papaspyrou
2015-11-17Add --enable-sharing-preserving configure flagYiannis Tsiouris
2015-11-17Add -debug +vc flag for debuging SHCOPYNikolaos S. Papaspyrou
This is very verbose, you have been warned. It should work with the copy-spy.py script, which may be a bit outdated.
2015-11-17Enable shcopy for spawning processesNikolaos S. Papaspyrou
2015-11-17Add machinery to enable SHCOPY dynamicallyNikolaos S. Papaspyrou
This commit is just for debugging purposes, will probably be reverted. It comes with a the erts_debug:copy_shared/1 BIF. If SHCOPY_DISABLE is defined, SHCOPY starts disabled and is dynamically enabled the first time that the BIF is called.
2015-11-17Remove DTrace Harddebug clutterBjörn-Egil Dahlberg
2015-11-17Enable shcopy for sending messagesNikolaos S. Papaspyrou
2015-11-17Add the BIF size_shared/1 and debug cleanupNikolaos S. Papaspyrou
2015-11-17Add all the main machineryNikolaos S. Papaspyrou
Add functions size_shared, copy_shared_calculate and copy_shared_perform. Add the infrastructure for making these communicate with each other. Add debug information to other places in the VM, to watch interaction with the sharing-preserving copy. CAUTION: If you define the SHCOPY_DEBUG macro (after SHCOPY is actually used in the VM) and make the whole OTP, there will be a lot of debugging messages during make (it will also be enabled in erlc). You have been warned...
