2010-12-01Miscellaneous rwmutex bug fixes and improvementsRickard Green
The ERTS internal rwlock implementation could get into an inconsistent state. This bug was very seldom triggered, but could be during heavy contention. The bug was introduced in R14B (erts-5.8.1). The bug was most likely to be triggered when using the read_concurrency option on an ETS table that was frequently accessed from multiple processes doing lots of writes and reads. That is, in a situation where you typically don't want to use the read_concurrency option in the first place.

2010-09-10Use mutex instead of rwlockRickard Green
Use mutex instead of rwlock since the read lock is more or less unused and it can be quite contended.

2010-09-09Make gen_tcp:recv/2 consistent with ssl:recv/2Björn Gustavsson
When the HTTP packet mode has been enabled for a socket, the ssl and gen_tcp modules have different error indications when there is an error while parsing the HTTP header: ssl:recv(SSLSocket, 0) -> {ok, {http_error, _Str}} gen_tcp:recv(Socket, 0) -> {error, {http_error, _Str}} We have decided to change gen_tcp:recv/2 to behave the same way as ssl:recv/2. That means that there will be always be an ok tuple if data could be succefully read from the socket, and an error tuple if there was a read error at the socket level.
2010-09-08Fix deadlock in reader optimized rwlock implementationRickard Green
A bug causing a deadlock in the reader optimized rwlock implementation has been fixed. This bug appeared in commit 59ee2a593090e7d53c97ceba63cbd300d1b9657e, i.e., it has not been seen in any released versions.

2010-09-08Re-enable spin wait on ethreads rwlocksRickard Green
Spin wait on most ethread rwlocks used by the runtime system was unintentionally disabled during development. Spin wait has now been enabled again. This bug appeared in commit 59ee2a593090e7d53c97ceba63cbd300d1b9657e, i.e., it has not been seen in any released versions.

2010-09-06Fix call to erts_gc_after_bif_call in hipe gluePaul Guyot
R12B-0 changed the signature of erts_gc_after_bif_call and it now takes 4 parameters instead of 2 in R11B-5. Yet, the glue code was not updated accordingly. As a result, the function erts_gc_after_bif_call was called with garbage and would randomly cause a crash later in the garbage collector code. The fix consists in passing NULL and 0 for the third and fourth parameters, since there is no term to add to rootset, recovering the behaviour of R11B-5 (see otp_src_R11B-5/erts/emulator/beam/erl_gc.c, line 314). (Includes assembly language fixes and code style improvements suggested by Mikael Pettersson.)

The scheduler wakeup threshold is now possible to adjust at system boot. For more information see the `+swt' command line argument of `erl'.
2010-09-04Lower the scheduler wakeup thresholdRickard Green
Lower the scheduler wakeup threshold since schedulers aren't spuriously woken as before (since commit 59ee2a593090e7d53c97ceba63cbd300d1b9657e).
2010-09-03inet: support retrieving MAC address on BSDMichael Santos
On systems supporting getaddrinfo(), support looking up the MAC address from inet:ifget/2. The results have the same quirks as with Linux: if the MAC address is longer than 6 bytes (e.g., fw0 under Mac OS X), the address is truncated; if the interface does not have a MAC address (e.g., lo0), an address consisting of 0's is returned.

Added erlang:system_info(build_type) which makes it easier to chose drivers, NIF libraries, etc based on build type of the runtime system.

2010-09-01Fix crash when calling erlang:system_info(update_cpu_info)Rickard Green
Calling erlang:system_info(update_cpu_info) on platforms where no CPU topology was found could result in a crash if other CPU information had changed. This bug was introduced in the 'dev' branch before R14B (commit 1b273b618002d65159453fdfb9520a9476e4423a). That is, the bug has never been seen in a released runtime system.
