2011-11-23Avoid slow code loading of BEAM code in a hipe-enabled emulatorBjörn Gustavsson
On my Linux computer, building the entire Erlang/OTP system with hipe disabled took about 8 minutes. With hipe enabled, but without any native code, the build took about 23 minutes, i.e. more than 3 times slower. (The computer has 4 cores, and I used 'make -j6'.) On my eight-core Mac (running 'make -j10') there was only a slight slowdown when hipe was enabled. The culprit is hipe_unified_loader:post_beam_load/1, which will be called every time a module is loaded (even if the module contains no native code). If post_beam_load/1 is called in a hipe-enabled emulator, it will block multi-scheduling, even if no work needs to be done. Apparently the cost for blocking multi-scheduling can vary greatly, depending on the operating system and system load. As a quick and conservative fix, don't call post_beam_load/1 unless some native code has been previously loaded.

2011-11-17Add restart_new_emulator instruction to kernel, stdlib and sasl appupsSiri Hansen
The appup files for kernel, stdlib and sasl did not contain any UpFromVsn and DownToVsn. This means that it was not possible to create a relup file with systool:make_relup if any of these applications had changed. This commit adds entries in the appup files for a maximum of two major releases back - all with only one upgrade instruction: restart_new_emulator. The point is to allow relups to be generated, but ensure that no soft upgrade is done for these three applications - i.e. they will always cause a restart of the emulator prior to all other upgrade instructions from other applications. Test cases (appup_test) are added to kernel_SUITE, stdlib_SUITE and sasl_SUITE. These all check that expected versions are matched in the appups, and illegal versions (older than two major releases, or in any other way illegal) do not match. The test is written in a general way where it is assumed that the version of these applications are stepped according the the rule that major releases step the second number, maintenance releases step the third number and patches step the fourth number.

inet:port/1 on peeled off socket returns 0. Bug? Who's?
2011-11-17erts,kernel: Return eprotonosupport when SCTP is not supportedRaimo Niskanen
It is better that gen_sctp:open/0-2 returns the informative Posix return code {error,eprotonosupport} than previously {error,badarg} when SCTP is not supported since it is so platform dependent.

On some platforms (FreeBSD) the #sctp_assoc_change{state=comm_up} event arriving during gen_sctp:connect/4,5 contains ancillary data #sctp_sndrcvinfo{}. That was not expected by the code.

2011-11-15Skip inet_res_SUITE tests when external resolver does not startRaimo Niskanen
E.g OpenBSD's (5.0) patched named does not allow itself to be started without privilige separation, which is only allowed for the superuser so test suites can not use that named. Fix the shell script that starts named to detect early exit from named and inform the Erlang code test suite what happened.
2011-11-15Add env var shutdown_timeout to kernel to avoid deadlock on node shutdownSiri Hansen
When a node is shutting down, application_controller will do exit(Pid,shutdown) on all application masters, and wait for {'EXIT',Pid,_}. If, for some reason, the application master does not terminate then application_controller will hang forever waiting for this 'EXIT' message. To overcome this problem, a configurable timer is added to kernel - the enviroment variable 'shutdown_timeout'. If this variable is set to a positive integer T, application_controller will do exit(Pid,kill) after T milli seconds if no 'EXIT' message is received.
2011-11-14Remove the undocumented function global:safe_whereis_name/1Hans Bolinder
2011-11-14Remove all use of global:safe_whereis_name/1Hans Bolinder
Calls to global:whereis_name/1 have been substituted for calls to global:safe_whereis_name/1 since the latter is not safe at all. The reason for not doing this earlier is that setting a global lock masked out a bug concerning the restart of supervised children. The bug has now been fixed by a modification of global:whereis_name/1. (Thanks to Ulf Wiger for code contribution.)

2011-09-29Skip create_big_boot on platforms without cryptoLukas Larsson
This has to be done as many other applications depend on that crypto is present.
2011-09-29Remove test_server path instead of cwd for clash testLukas Larsson
With the introduction of common_test as test framework the working directory of the tests changed to be the emulator_test directory. So we now have to remove the ../test_server directory instead. This change only affect tests run with a emulator which has not been installed.

Solaris version before 10 have some problem with releasing addresses after doing a gen_udp:open, which causes inet_res to get a econnrefused. With this fix we hope that the static port will not collide with anything.
