2014-01-17erts: Refactor ESTACK & WSTACK to use a struct easy to "export"Sverker Eriksson
This is not a clean refactor. It changes the behaviour slightly of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used as-is and not copied into default_stack. This will hopefully fix an illusive memory leak that valgrind is reporting.

2014-01-15fix system_flag deprecation warningsSteve Vinoski
Passing cpu_topology or scheduler_bind_type to erlang:system_flag/2 results in an error report warning that the argument is deprecated and is slated for removal in erts-5.10/OTP-R16. Since we're already past that version and no substitute approach has yet been decided for these features, keep the deprecation warning but bump the removal version it mentions up to Erlang 18.

2014-01-15remove deprecated driver_async_cancel functionSteve Vinoski
Some time ago the driver_async_cancel function was deprecated and slated for removal in R17. This commit removes the function along with its associated tests and documentation, sets the ERL_DRV_EXTENDED_MAJOR_VERSION to 3 and ERL_DRV_EXTENDED_MINOR_VERSION to 0, and modifies the sys_info_base_drv and sys_info_prev_drv tests in the driver test suite to check version 3.0 instead of 2.0.
2014-01-14Don't make gzio.c dependent on the zutil.h header fileBjörn Gustavsson
gzio.c is our own replacement for zlib's gzopen() etc (based on a version of gzio.c that was included in an old version of zlib). Unfortunately, gzio.c still depends on the *internal* zlib header file zutil.h which is not supposed to be used outside of the zlib source code. The dependencies are the use of the gzFile typedef and the F_OPEN() macro. Instead of gzFile, define and use our own ErtsGzFile. To get rid of the F_OPEN() macro, call open() of _wfopen() directly.

2014-01-10erts: Make sure fds 0,1 and 2 are openLukas Larsson
If they are not open a really nasty race where the io pipe in erl_poll got fd 0 and the fd_driver setting fd 0 to blocking could occur. This caused the emulator to hang during shutdown.
2014-01-10erts: Run binary_SUITE:trapping even for 32bitSverker Eriksson
Not sure why it was disabled for 32bit in the first place?

and rename it 'trapping'.
2014-01-10erts: Remove the extra_root feature from the process structureSverker Eriksson
as we don't use it and instead have the feature to disable GC during trapping BIFs.
2014-01-10erts: Simplify term_to_binary by removing saved ESTACK from root setSverker Eriksson
We disabled GC (in 522a29666088d5) during trapping and don't need to include the saved ESTACK as part of root set.

2014-01-09erts: Increase gc tenure rateBjörn-Egil Dahlberg
The garbage collector tries to maintain the previous heap block size during a minor gc, i.e. 'need' is not utilized in determining the size of the new heap, instead it relies on tenure and garbage to be sufficiently large. In instances during intense growing with exlusively live data on the heap coupled with delayed tenure, fullsweeps would be triggered directly after a minor gc to make room for 'need' since the new heap would be full. To remedy this, the tenure of terms on the minor heap will always happen (if it is below the high watermark) instead of every other minor gc.

2014-01-07erts: Fix bs_get_integer instructionBjörn-Egil Dahlberg
The instruction bs_get_integer could unnecessarily trigger a garbage collection in failure cases which is unwanted or outright dangerous. Ex: <<X:Sz,_/bits>> = <<"some binary">> Previously, if Sz induced X to a bignum it would reserved memory size this on the heap via a garbage collection before checking if the size could actually match. It will now check the binary size before triggering a collection.
