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.
2010-05-20sys.h: Correct the get_int64() macroBjörn Gustavsson
The get_int64() macro has never been used (it was probably added for completeness at the same time that put_int64() was added), but it was not actually used and therefore it does not actually work.

* mp/fix-erts_poll_info_kp-livelock: fix livelock in erts_poll_info_kp() OTP-8632 mp/fix-erts_poll_info_kp-livelock When kernel poll has been enabled, a livelock could in rare circumstances occur. Problem reported by Chetan Ahuja, fix by Mikael Pettersson.

2010-05-15fix livelock in erts_poll_info_kp()Mikael Pettersson
erts_poll_info_kp() [defined in erts/emulator/sys/common/erl_poll.c via some name-mangling trickery] contains a code path that can end up in an infinite loop, causing a livelock. There is a block of code inside #if ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE that is supposed to iterate over a linked list of ErtsPollSetUpdateRequestsBlocks and update two variables based on the sizes of these blocks. The bug is that the loop forgets to advance the list pointer to the next element, so if the loop is entered at all (the initial list pointer is non-NULL), the thread falls into an infinite loop. This patch, against R13B03 but applies fine to today's git, fixes the bug by adding a statement to advance the list pointer in the loop. All other loops over this list appear to be correct. Thanks to Chetan Ahuja for the original report of a livelock problem in erts_poll_info_kp().

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.

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.)

2010-05-11erts: Implement recv_mark/1 and recv_set/1 for realBjörn Gustavsson
The recv_mark/1 instruction will both save the current position in the message queue and a mark (the address of the loop_rec/2 instruction just following the recv_set/1 instruction). The recv_mark/1 instruction will only use the saved position if the mark is correct. The reason for saving and verifying the mark is that the compiler does not need to guarantee that no other receive instruction can be executed in between the recv_mark/1 and recv_set/1 instructions (the mark will be cleared by the remove_message/0 instruction when a message is removed from the message queue). That means that arbitrary function calls in between those instruction can be allowed.
