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.

* rickard/rwmtx-spin/OTP-8819: Fix deadlock in reader optimized rwlock implementation Remove unused variables Increase spincount with many schedulers Re-enable spin wait on ethreads rwlocks
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.)

2010-09-06Remove warning about experimental status of NIFs from erlang.xmlPatrik Nyblom
Also made the SEEALSO link at the bottom of erl_nif.xml more "erlangish".
2010-09-06Stop leaking memory in nif_SUITE:send* testcasesPatrik Nyblom
The make_term_n function in nif_SUITE.c created resources that never got released, creating valgrind memcheck Definitely Lost warnings.
2010-09-04Add scheduler wakup threshold as command line argumentRickard Green
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.
2010-09-02Add erlang:system_info(build_type)Rickard Green
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.

2010-08-31Fix anomalies in epmd not yet reported as security issuesPatrik Nyblom
Use erts_(v)snprintf to ensure no buffer overruns in debug printouts. Disallow everything except port and name requests from remote nodes. Disallow kill command even from localhost if alive nodes exist. -relaxed_command_check when starting epmd returns the possibility to kill this epmd when nodes are alive (from localhost). Disallow stop command completely except if -relaxed_command_check is given when epmd was started. Environment variable ERL_EPMD_RELAXED_COMMAND_CHECK can be set to always get -relaxed_command_check.
