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.
2011-12-02Only 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.
2011-12-01Implement 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.
2011-11-30erlang: 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.
2011-11-29Implement 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."
2011-11-17erts,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.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

2011-09-26erl_prim_loader: Eliminate dialyzer warningBjörn Gustavsson
The concat/1 function is now only used to append lists when constructing filenames. Thus it is too general and the first clause (that handles characters) will never be used. We could just remove the clause that is never used, but then the name 'concat' would be misleading and someone could use misuse it. Therefore, replace concat/1 with the join/2 function that can only be used for joining filename components.

2011-07-06Remove deprecated concat_binary/1Björn Gustavsson
concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

2011-06-08Teach prim_file:list_dir/1,2 to use fname chunksBjörn-Egil Dahlberg
The efile driver will now use chunked data on list_dir. This will lessen the number of sends to prim_file and hence improve performance. This method is utilized in both direct and async cases.
2011-06-08Replace atom in DRV macro in prim_file with stringStavros Aronis
An experimental version of Dialyzer discovered that the atom that replaced the DRV macro in prim_file ends up in calls to erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The documentation states that this call requires a string there. This change is also consistent with the one introduced in commit 0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

2010-10-20Teach -init_debug to print info about on_load handlers begin runBjörn Gustavsson
2010-10-20Fix hang in on_load handlers in embedded modeBjörn Gustavsson
In embedded mode, all on_load handlers will be called after loading all modules but before starting any servers. Therefore, if an on_load handler calls any function in the code module that calls the code server (such as code:priv_dir/1), there will be a deadlock because the code server has not yet been started. Fix this problem by invoking the on_load handlers after having started most servers in the kernel application.
