2011-12-02Merge branch 'ta/sendfile/OTP-9240'Lukas Larsson
* ta/sendfile/OTP-9240: (31 commits) Add sendfile server printouts Skip recv/send during tests for fallback platforms Remove header/trailer support Remove windows implementation Expand sendfile documentation Only allow tcp sockets as target for sendfile Move sendfile api to file module Preliminary work on header/trailer Use free_sendfile explicitly for non-async Remove debug printouts Add tests for send/recv/sendfile interactions Remove tests for file_server sendfile sendfile caller now has to be the controlling_process Remove support for file_server, sendfile has to be raw Set chunk size to 3 GB Change type of fd to be ErlDrvEvent Add ifdef's for HAVE_SENDFILE Fix freebsd support for sendfile Change nbytes to 64 bit Implement ignorefd for TCP ...
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
2011-12-01Preliminary 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.

2011-12-01Add 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 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.

* tn/inet_drv-fix: Cleanup - remove unnecesary bracket level and configure for ifreq.ifr_enaddr Work around gcc linking with own view of default libs on Solaris Use libdlpi to get physical address
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."

Also use 64-bit lib when necessary, specify runtime lib path for secondary dependency libs, and better check before using SIOCGIFHWADDR.

2011-10-06erts: Fix write-after-free bug in inet driverSverker Eriksson
Bug caught by valgrind but never confirmed as cause of a real problem. Triggered by emulator_test/distribution_SUITE:bad_dist_structure when bad data is received to a distribution port. Port is closed by erts_net_message() and the freed port data is then later used when returning to inet_drv. Everything happens in the same call to tcp_inet_input(). ==32592== Invalid read of size 8 ==32592== at 0x5B6D8C: tcp_deliver (inet_drv.c:8536) ==32592== by 0x5B720E: tcp_recv (inet_drv.c:8652) ==32592== by 0x5B7753: tcp_inet_input (inet_drv.c:8990) ==32592== by 0x5B7FA5: tcp_inet_drv_input (inet_drv.c:9257) ==32592== by 0x4B900C: erts_port_task_execute (erl_port_task.c:856) ==32592== by 0x4AC873: schedule (erl_process.c:5511) ==32592== by 0x5527CA: process_main (beam_emu.c:1225) ==32592== by 0x4A9958: sched_thread_func (erl_process.c:3789) ==32592== by 0x5E2971: thr_wrapper (ethread.c:106) ==32592== by 0x4FEA142: start_thread (in /lib64/libpthread-2.4.so) ==32592== by 0x52C374C: clone (in /lib64/libc-2.4.so) ==32592== Address 0x9b13ea8 is 440 bytes inside a block of size 488 free'd ==32592== at 0x4A1FE94: free (vg_replace_malloc.c:366) ==32592== by 0x58AE69: erts_sys_free (sys.c:2588) ==32592== by 0x48E54F: erts_free (erl_alloc.h:218) ==32592== by 0x497390: driver_free (io.c:3527) ==32592== by 0x5B2E77: inet_stop (inet_drv.c:7152) ==32592== by 0x5B502F: tcp_inet_stop (inet_drv.c:7855) ==32592== by 0x492E60: terminate_port (io.c:1849) ==32592== by 0x493971: erts_do_exit_port (io.c:2059) ==32592== by 0x4CEE01: erts_net_message (dist.c:1508) ==32592== by 0x496AC1: driver_output2 (io.c:3294) ==32592== by 0x5AAA69: inet_port_data (inet_drv.c:1894) ==32592== by 0x5AD57E: tcp_reply_data (inet_drv.c:3181) ==32592== by 0x5B6D84: tcp_deliver (inet_drv.c:8533) ==32592== by 0x5B720E: tcp_recv (inet_drv.c:8652) ==32592== by 0x5B7753: tcp_inet_input (inet_drv.c:8990) Fixed by checking the negative return code earlier in tcp_deliver().
