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.
2011-11-29Implement 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."

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.

2011-11-17external.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.

2011-11-16Make OTP build w/alternative gcc on MacOS LionPatrik Nyblom
Requires own build of wxMac for wx to work: $ arch_flags="-arch i386" $ ./configure CFLAGS="$arch_flags" CXXFLAGS="$arch_flags" \ CPPFLAGS="$arch_flags" LDFLAGS="$arch_flags" OBJCFLAGS="$arch_flags" \ OBJCXXFLAGS="$arch_flags" --prefix=/usr/local \ --with-macosx-sdk=/Developer/SDKs/MacOSX10.6.sdk \ --with-macosx-version-min=10.6 --enable-unicode --with-opengl $ make $ sudo make install - and we have macports gcc 4.5 in /opt/local/bin, so we configure and build OTP like this for 32bit (which is required for wx): $ cd $ERL_TOP $ PATH=/usr/local/bin:$PATH CC=/opt/local/bin/gcc-mp-4.5 CXX=/opt/local/bin/g++-mp-4.5 ./configure --enable-m32-build $ MAKEFLAGS="-j6" PATH=/usr/local/bin:$PATH make

2011-11-14erlc: Do not bind schedulers when invoking "erl"Björn Gustavsson
If parallel make is used, several instance of 'erlc' is likely to be invoked at once. Therefore, the default binding of schedulers to CPU cores will do no good. (With this change, the build of Erlang/OTP with six threads finished in about 7 minutes; without in about 11 minutes.)
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.
2011-11-14beam_load.c: Factor out cleaning up of the loader state into free_state()Björn Gustavsson
2011-11-14BEAM loader: Clean up handling of error reasonsBjörn Gustavsson
There is no reason to have erts_load_module() return integer values, only to have the caller convert the values to atoms. Return the appropriate atom directly from the place where the error is generated instead. Return NIL if the module was successfully loaded.
