2011-12-05Clarify some code commentsLukas Larsson
Thanks Tuncer Ayaz
2011-12-05Make solaris use sendfilevLukas Larsson
sendfilev is a richer API which allows us to do non blocking TCP on solaris. The normal sendfile API seems to have some issue with non blocking sockets and the return value of sendfile.
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.

2011-12-01Change 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.

2011-12-01Make 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.
2011-11-29Implement 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."

2011-11-17external.c: Remove the option to create over-sized heap binariesBjörn Gustavsson
Since refc binaries are now supported in literal pools, there is no longer any need to allow the creation of over-sized heap binaries.
2011-11-17Allow refc binaries in literal poolsBjörn Gustavsson
To simplify the implementation of literal pools (constant pools) for the R12 release, a shortcut was taken regarding binaries -- all binaries would be stored as heap binaries regardless of size. To allow a module containing literals to be unloaded, literal terms are copied when sent to another process. That means that huge literal binaries will also be copied if they are sent to another process, which could be surprising. Another problem is that the arity field in the header for the heap object may not be wide enough to handle big binaries. Therefore, bite the bullet and allow refc binaries to be stored in literal pools. In short, the following need to be changed: * Each loaded module needs a MSO list, linking all refc binaries in the literal pool. * When check_process_code/2 copies literals to a process heap, it must link each referenced binary into the MSO list for the process and increment the reference counter for the binary. * purge_module/1 must decrement the reference counter for each refc binary in the literal pool.

2011-11-17BEAM loader: Don't stop other schedulers until truly neededBjörn Gustavsson
The erlang:module_load/2 BIF will stop all other schedulers before it starts to process the BEAM file. That is not a problem when starting the Erlang/OTP system, since the start-up is mostly sequential. It is a problem, however, when big BEAM files are loaded in an already running system. After the refactoring in the previous commits, we can now do most of the processing of the BEAM file before we stop the other schedulers, so that we can minimize the time when only one scheduler will be running.

2011-11-14BEAM loader: Refactor code loading into separate functionsBjörn Gustavsson
Break apart code loading into the three functions: erts_alloc_loader_state() erts_prepare_loading() erts_finish_loading() The erts_alloc_loader_state() and erts_prepare_loading() can be executed with all schedulers running. Only erts_finish_loading() needs to be run in a single-scheduling system.
