2012-03-22Rename dyntrace BIFs to more suiting namesPatrik Nyblom
2012-03-22Correct some errors in the user tag spreadingPatrik Nyblom
2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.
2012-03-22Update dtrace for changes in R15Björn-Egil Dahlberg
2012-03-22Add DTrace support for OS X, Solaris, and Linux (via SystemTap), 4/4Scott Lystig Fritchie
Add probes to (mostly) the efile_drv.c driver and other file I/O-related source files.
2012-03-20Make 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. The problem was addressed in OTP-9764, but the situation was not improved in all cases. Thanks to Richard Carlsson.

* bjorn/kernel/on_load-bug/OTP-9875: Fix on_load handling in modules loaded by code:load_binary/3
2012-01-23Fix on_load handling in modules loaded by code:load_binary/3Björn Gustavsson
In "13.4 Running a function when a module is loaded" in the Reference Manual, it is said that: A process that calls any function in a module whose on_load function has not yet returned will be suspended until the on_load function has returned. That did not work if the module was loaded using code:load_binary/3. Instead, the callers would get an 'undef' exception.
2012-01-23Correct two contracts in gen_sctp.erlHans Bolinder
binary should be binary().
2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.

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."
