* sverk/misc-bug-fixes:
erts: Fix faulty assert in match spec engine.
erts: Fix crash when comparing very large floats with integers
erts: Refactor big-float compare on HALFWORD to use C-stack

* lukas/erts/sendfile_passive_mode_fix/OTP-11614:
erts: fix bug when using passive mode and sendfile
|
|
The bug incorrectly issued driver_select when un-ignoring an fd
for a socket in passive mode, which caused an incorrect error
tuple to be returned when the remote end closed the connection.

big_buf was one word too short on 32-bit emulators causing
memory corruption.
Seems like this did not cause a problem before the ESTACK memory layout
was changed in 172ebf11dc455e22b87f.

for the temporary conversion from float to big.
Preparation for coming bugfix of 'big_buf' array size.

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.

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.

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.

* rickard/otp-17-vsn-fix:
Fix issues with new versioning
|
|
* lukas/erts/fix_sp_usage_printout/OTP-11559:
erts: Replace tab with space for proper alignment
|
|
* lukas/erts/fd0_pipe_bug/OTP-11558:
erts: Make sure fds 0,1 and 2 are open
|
|
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.

Not sure why it was disabled for 32bit in the first place?
|
|
and rename it 'trapping'.
|
|
as we don't use it and instead have the feature to disable GC
during trapping BIFs.
|
|
We disabled GC (in 522a29666088d5) during trapping and don't need to
include the saved ESTACK as part of root set.

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.

* rickard/idoc:
Add misc internal documentation
|
|
|
|
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.
