Don't use both HAVE_SYSTEMD_DAEMON and HAVE_SYSTEMD_SD_DAEMON - use only
the former one and remove the latter one entirely.

* lukas/erts/isfinite-fix/OTP-12268:
erts: Use finite instead of isfinite with gcc
|
|
Turns out that isfinite emits a function call and not
an instruction in gcc, this makes estone float arith
about 50-75% slower. finite emits the instruction so
we use that instead.

Remove comments about unicode atoms in OTP 18

* s1n4/zlib_doc_typo:
Fix a typo in the zlib documentation
|
|
There was once a plan to implement support for unicode atoms in OTP
18. This plan has been stopped until further notice, and the
information about this is now removed from the documentation.

Ensure that the return value from a dirty NIF call is made part of the GC
rootset. Add a new regression test to nif_SUITE.
Thanks to Daniel Goertzen for reporting the error and providing a test
case, and to Sverker Eriksson for making test case reproducible and finding
the fix.

This patch allows checking for NIF API version in a way similar to
driver version. E.g. by calling erlang:system_info(nif_version).

Need to include sys/ioctl.h for TIOCSWINSZ to be defined.
Seems this was broken when refactoring run_erl for OSE in OTP 17.0.

Symptom: VM on OSX (darwin11.4.2) with +Meamin running sasl tests,
crashing when init:reboot() does erlang:purge_module(installer).
Problem: Off-by-one bug in beam_ranges:find_range, returning the wrong
range if the 'end' of one module is the 'start' of the next. This is only
possible if using sys_alloc (+Meamin) as our own allocators always put
block headers between allocated payload data.

OS X Mavericks builds result in a number of warnings about finite() being
deprecated, like these:
beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations]
ERTS_FP_ERROR(p, f1.fd, goto badarith);
^
sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR'
^
sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR'
^
/usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here
extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA);
Add checks to use isfinite() instead of finite() where available. Verified
on OS X Mavericks 10.9.5 and Ubuntu 12.04.

Running "erl -smp disable" on an emulator built with dirty scheduler
support caused problems such as segmentation violations and emulator status
line outputs containing garbage. For example:
$ erl -smp disable
Segmentation fault (core dumped)
and:
$ erl -smp disable
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [ds:10:4297895689:4299948152] [async-threads:280]
This problem also caused the emulator smoke_test_SUITE to hit these same
problems if run in an emulator started with the "-smp disable" option.
Fix this segmentation violation by ensuring that dirty scheduler
information is printed in the status line only when the emulator is
compiled with ERTS_SMP enabled.
With this fix in place, the smoke_test_SUITE now passes when the "-smp
disable" option is used, and the emulator status line prints correctly for
both "-smp enable" and "-smp disable":
$ erl -smp enable
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [kernel-poll:false]
and:
$ erl -smp disable
Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [async-threads:10] [kernel-poll:false]

Symptom: base64_SUITE:roundtrip crashes with hipe compiled stdlib.
Problem: HIPE_WRAPPER_BIF_DISABLE_GC pushed a "trap frame", but the frame
was only popped if the call was recursive.
Solution: Only reserve "trap frame" if BIF call is recursive.
|
|
The trap_frame got pushed twice, first by the wrapper then by
hipe_push_beam_trap_frame as it was looking at F_DISABLE_GC.

Set IN_POOL flag _after_ mbc has been actually inserted.
Earlier it did not matter if IN_POOL was set early as it was not possible
to find a carrier before is was fully inserted. Now when searching
pooled_list and traitor_list we must make sure a found carrier has been
fully inserted into cpool before removing it.
|
|
Code incorrectly relied on undefined C behavior. Clang and gcc 4.9 do not behave
as code expected. This affected cores and processors detection on FreeBSD.
