2010-05-20Add file:advise/4 - a wrapper to the POSIX syscall posix_fadviseFilipe David Manana
Useful for informing the Operating System about the access pattern for a file's data, so that it can adapt the caching strategy to maximize disk IO performance.
2010-05-20Add file:datasync/1 for syncing file contents onlyFilipe David Manana
file:datasync/1 invokes the POSIX system call "int fdatasync(int fd)". This system call is similar to "fsync" but, unlike fsync, it does not update the metadata associated with the file (like the access time for example). It's used by many DBMSs (MySQL and SQLite of example) to increase disk IO performance, as it avoids disk seeks and disk write operations compared to fsync. More details on it at: http://linux.die.net/man/2/fdatasync An example, from the MySQL source: http://bazaar.launchpad.net/~mysql/mysql-server/mysql-5.1-telco-6.1/annotate/head%3A/mysys/my_sync.c#L61 This new function just calls fsync on systems not implementing fdatasync.

The documentation of lists:keysort/2 states that the sort is stable.
2010-05-12Remove opaque declarations from the attributesBjörn Gustavsson
-opaque declarations should not be retained in the attributes (because they will be loaded along with the code and are not useful). While at it, filter away those Dialyzer attributes as early as possible - in v3_kernel.
2010-05-12Merge branch 'bg/opt-receive' into devErlang/OTP
* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)

* bg/beam_lib: Remove redundant includes Make beam_lib:cmp/2 stricter OTP-8625 bg/beam_lib The beam_lib:cmp/2 function now compares BEAM files in stricter way. The BEAM files will be considered different if there are any changes except in the compilation information ("CInf") chunk. beam_lib:cmp/2 used to ignore differences in the debug information (significant for Dialyzer) and other chunks that did not directly change the run-time behavior.

2010-05-11compiler tests: Cover the error handling code in beam_receiveBjörn Gustavsson
2010-05-11compiler test: Test optimization of receive statementsBjörn Gustavsson
We don't attempt to run the generated code, but use beam_disasm and check for the presence or absence (as appropriate) of the recv_mark/1 and recv_set/1 instructions.
2010-05-11Optimize selective receives in the presence of a large message queueBjörn Gustavsson
If a gen_server process has many messages in its message queue and calls another gen_server process, the selective receive in gen_server:call() will have to go through the entire message queue. Have the compiler generate the new mark_recv/1 and mark_recv/1 instructions that can avoid going through the entire message queue.
2010-05-11Introduce the new recv_mark/1 and recv_mark/1 instructionsBjörn Gustavsson
Make the recv_mark/1 and recv_mark/1 instructions known to the compiler and run-time system. For the moment, make the loader ignore any occurrences of those instructions in BEAM files. Also update hipe_beam_to_icode to ignore those instructions.

R12 nodes cannot load code that use the optimized receive that we are about to implement.
