* hb/kernel/too_greedy_disk_log/OTP-9764: Make sure disk_log does not write too much data
2011-12-04Make sure disk_log does not write too much dataHans Bolinder
While disk_log eagerly collects logged data for better performance, collecting too much data may choke the system and cause huge binaries to be written. (Reported by Klarna.) (Logging data faster than the speed disk_log can write to disk can still cause problems.)

2011-12-02Remove header/trailer supportLukas Larsson
Since the API for headers/trailers seem to be very awkward to work with when using non-blocking io the feature is dropped for now. See unix_efile.c for more details.
2011-12-02Expand sendfile documentationLukas Larsson
2011-12-02Move sendfile api to file moduleLukas Larsson
Since sendfile could in theory be used to send to any type of file descriptor in *nix, it is a better fit to have it in file.
2011-12-01Preliminary work on header/trailerLukas Larsson
Have to figure out how to represent progress in header writing when using non-blocking, not sure how to do this.
2011-12-01sendfile caller now has to be the controlling_processLukas Larsson
This is needed because otherwise there could be scenarios when the efile driver blocks a fd and then crashes without the inet driver ever finding out. Now when the process crashes the port will close and we can cleanup in the inet driver.
2011-12-01Remove support for file_server, sendfile has to be rawLukas Larsson
Because the sending process has to be the controlling process of the tcp socket used to send data it is not possible to use the file_server
2011-12-01Implement ignorefd for TCPLukas Larsson
Ignore fd is a feature used by sendfile to temporarily remove all driver_select calls on that fd so that another driver can select on it. It also delays all actions which sends or receives data in that fd until in the fd is no longer ignored. Only the controlling_process should use the feature as it is otherwise possible that the ignore will never be cleaned up and hence create a memory leak in the driver. An ignored driver will not detect that an fd has been closed until it is unignored.
2011-12-01Implement blocking calls for sendfileLukas Larsson
Move sendfile data to invoke data instead of file_descr. Remove usage of ready_output when doing a send. If told to send 0 bytes, file_sendfile now sends the entire file for linux.
2011-12-01Implement sendfile using blocking io in asynch threadsLukas Larsson
Move the command handling to outputv in preparation for header and trailer inclusion in the sendfile api. Use the standard efile communication functions for sendfile.
2011-12-01Create erlang fallback for sendfileLukas Larsson
Created erlang fallback for sendfile in gen_tcp and moved sendfile from file to gen_tcp. Also created testcases for testing all different options to sendfile. For info about how sendfile should work see the BSD man pages as they contain a more complete API than other *nixes.
2011-12-01Correct callback spec in application moduleStavros Aronis
2011-11-29Implement file:sendfileTuncer Ayaz
Allow Erlang code to use sendfile() where available by wrapping it as file:sendfile/4 and file:sendfile/2. sendfile(2) - Linux man page: "sendfile() copies data between one file descriptor and another. Because this copying is done within the kernel, sendfile() is more efficient than the combination of read(2) and write(2), which would require transferring data to and from user space."
2011-11-29user_sup: Eliminate use of tuple funBjörn Gustavsson
2011-11-26code: Clean up loading of code_server prerequisitesBjörn Gustavsson
Reorganize in a systematic way the code that loads the modules needed by the code_server process. While at it, remove the useless hipe_unified_loader:load_hipe_modules/0 function.
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.

2011-11-17kernel: Bugfix - SCTP connect with sndrcvinfo in assoc_change eventRaimo Niskanen
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.

2011-11-15Add 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.)
2011-11-01Fix a crash when file:change_time/2,3 are called with invalid datesAhmed Omar
Calling file:change_time/2,3 with an invalid date tuple (e.g file:change_time("file.txt", {undefined, undefined})) will cause file_server_2 to crash. error_logger will shutdown and the whole VM will stop. Change behavior to validate given dates on system boundaries. (i.e before issuing a server call).
