2011-12-02Mend the non-SMP emulatorBjörn Gustavsson
Commit 8781932b3b8769b6f208ac7c00471122ec7dd055 broke erlang:system_info(system_version) in the non-SMP emulator so that it would typically dump core. "rq:%d" was removed from the format string for erts_printf(), but the corresponding argument in the argument list was not removed, which ultimately caused "kernel-poll:%s" to be passed an integer (typically 0).
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.
2011-12-02Remove windows implementationLukas Larsson
2011-12-02Only allow tcp sockets as target for sendfileLukas Larsson
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.
2011-12-01Use free_sendfile explicitly for non-asyncLukas Larsson
This is needed because aync job will not call free_sendfile if there is an async_ready callback.
2011-12-01Remove debug printoutsLukas Larsson
2011-12-01Set chunk size to 3 GBLukas Larsson
It is not possible to use the maximum size_t/off_t for the chunks as that causes sendfile to return einval. 3GB seems to work on all *nix platforms.
2011-12-01Change type of fd to be ErlDrvEventLukas Larsson
2011-12-01Add ifdef's for HAVE_SENDFILELukas Larsson
2011-12-01Fix freebsd support for sendfileLukas Larsson
2011-12-01Change nbytes to 64 bitLukas Larsson
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.
2011-12-01Fix offset calculation for darwinLukas Larsson
2011-12-01Fix cleanup for sendfileLukas Larsson
2011-12-01Fix 32 bit parametersLukas Larsson
2011-12-01Make socket blocking if there are async threadsLukas Larsson
2011-12-01Implement sendfile when there are no async threadsLukas Larsson
When there are no async threads sendfile will use the ready_output select on the socket fd to know when to send data. The file_desc will also be put in the sending sendfile_state which buffers all other commands to that file until the sendfile is done.
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.
2011-12-01Remove output from driver entryLukas Larsson
outputv will always be used so removed output to decrease confusion.
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.

2011-12-01Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topologyRickard Green
The use of erlang:system_flag(scheduler_bind_type, _) and erlang:system_flag(cpu_topology, _) have been deprecated and scheduled for removal in erts-5.10/OTP-R16. For more information see the documentation of erlang:system_flag/2.
2011-12-01Remove common run-queue in SMP caseRickard Green
The common run-queue implementation is removed since it is unused, untested, undocumented, unsupported, and only complicates the code. A spinlock used by the run-queue management sometimes got heavily contended. This code has now been rewritten, and the spinlock has been removed.
2011-12-01Fix scheduler suspend bugRickard Green
Calls to erlang:system_flag(schedulers_online, N) and/or erlang:system_flag(multi_scheduling, block|unblock) could cause internal data used by this functionality to get into an inconsistent state. When this happened various problems occurred. This bug was quite hard to trigger, so hopefully no-one has been effected by it.
2011-11-30erlang: Eliminate a clause in aa_mem_data/2 that can never matchBjörn Gustavsson
aa_mem_data/2 is only called by aa_mem_data/1 and itself. aa_mem_data/1 called with the argument 'notsup' will never call aa_mem_data/2. aa_mem_data/2 will only call itself with a #memory{} record as the first argument. QED. Noticed-by: Dialyzer.

2011-11-30Disable floating point exceptions on Mac OS X by defaultBjörn Gustavsson
Many test cases provoke printouts similar to: ERTS_FP_CHECK_INIT at 0x131fd218: detected unhandled FPE at 0x1 Until the problem has been identified and fixed, disable floating point exceptions by default on Mac OS X.
2011-11-30erts: Warn the first time a tuple fun is calledBjörn Gustavsson
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."
2011-11-29big_SUITE: Eliminate use of tuple funBjörn Gustavsson
It seems that a tuple fun was used only because erl_eval:expr/3 did not support passing in a real fun at the time that the test case was originally written.

2011-11-29erl_process.c: Remove the redundant variable 'processes_busy'Björn Gustavsson
There is a static variable called 'processes_busy' in erl_process.c, which will be incremented but never used. To confuse things, there is also a global variable with the same name, but it it is only defined and used if BM_COUNTERS is defined. In erl_process.c, the global version of 'processes_busy' will be seen and incremented if BM_COUNTERS is defined. Remove the static version of 'processes_busy' in erl_process.c, but keep the global version if BM_COUNTERS is defined. Noticed-by: Jovi Zhang
