2014-02-24ose: Add module that allows interaction with any OSE processLukas Larsson
The interface of this module is made to be as generic as possible in order for other IPC mechanisms to mimic it and allow porting of code between different os:es.
2014-01-27erts/kernel: sendfile no longer uses async threadsLukas Larsson
This has been done because a slow client attack is possible if the async thread pool is used. The scenario is: Client does a request for a file and then slowly receives the file one byte at a time. This will eventually fill the async thread pool with blocking sendfile operations and thus starving the vm of all file operations. If you still want to use the async threads pool for sendfile an option to enable it has been introduced.

Update versions of OTP, erts, kernel, and stdlib to comply with the new version scheme decided by the OTP technical board.

2013-11-18Parallel check_process_code when code_server purge a moduleRickard Green
When the code_server is about to purge a module it will now issue asynchronous check_process_code requests to all processes at once instead of one at a time. These check_process_code operation can execute in parallel.

2013-11-15Add sync option to file:open/2Joseph Blomstedt
The sync option adds the POSIX O_SYNC flag to the open system call on platforms that support the flag or its equivalent, e.g., FILE_FLAG_WRITE_THROUGH on Windows. For platforms that don't support it, file:open/2 returns {error, enotsup} if the sync option is passed in. The semantics of O_SYNC are platform-specific. For example, not all platforms guarantee that all file metadata are written to the disk along with the file data when the flag is in effect. This issue is noted in the documentation this commit adds for the sync option. Add a test for the sync option. Note however that the underlying OS semantics for O_SYNC can't be tested automatically in any practical way, so the test assumes the OS does the right thing with the flag when present. For manual verification, dtruss on OS X and strace on Linux were both run against beam processes to watch calls to open(), and file:open/2 was called in Erlang shells to open files for writing, both with and without the sync option. Both the dtruss output and the strace output showed that the O_SYNC flag was present in the open() calls when sync was specified and was clear when sync was not specified.
2013-11-09Add os:unsetenv/1Martin Hässler
New BIF os:unsetenv/1 which deletes an environment variable and returns 'true'. Does not change any old functionality. Calls the libc function unsetenv(3) on UNIX and SetEnvironmentVariableW(key, NULL) on Windows. The unicode support is the same as for os:getenv and os:putenv.

2013-09-23add {active,N} socket option for TCP, UDP, and SCTPSteve Vinoski
Add the {active,N} socket option, where N is an integer in the range -32768..32767, to allow a caller to specify the number of data messages to be delivered to the controlling process. Once the socket's delivered message count either reaches 0 or is explicitly set to 0 with inet:setopts/2 or by including {active,0} as an option when the socket is created, the socket transitions to passive ({active, false}) mode and the socket's controlling process receives a message to inform it of the transition. TCP sockets receive {tcp_passive,Socket}, UDP sockets receive {udp_passive,Socket} and SCTP sockets receive {sctp_passive,Socket}. The socket's delivered message counter defaults to 0, but it can be set using {active,N} via any gen_tcp, gen_udp, or gen_sctp function that takes socket options as arguments, or via inet:setopts/2. New N values are added to the socket's current counter value, and negative numbers can be used to reduce the counter value. Specifying a number that would cause the socket's counter value to go above 32767 causes an einval error. If a negative number is specified such that the counter value would become negative, the socket's counter value is set to 0 and the socket transitions to passive mode. If the counter value is already 0 and inet:setopts(Socket, [{active,0}]) is specified, the counter value remains at 0 but the appropriate passive mode transition message is generated for the socket. This commit contains a modified preloaded prim_inet.beam due to changes in prim_inet.erl. Add tests for {active,N} mode for TCP, UDP, and SCTP sockets. Add documentation for {active,N} mode for inet, gen_tcp, gen_udp, and gen_sctp.

2013-07-11Add application:ensure_all_started/1-2Fred Hebert
This adds two new functions to the application module that will recursively look for missing dependencies to start the entire dependency chain of a given application, and then the application itself, if possible. Its entire behavior is based on the currently existing 'start/1-2' functions, which will report dependencies that have not yet been started and other problems encountered. 'ensure_all_started/1-2' will use this information the way any programmer would manually do it to automate the process. This kind of functionality, while not OTP-ish (releases do this start sequence for the user), is still useful for testing purposes, quick demonstrations, and programmers who do not wish or know how to use OTP releases. The function returns '{ok, StartedApps}' for all started or already started applications (already started are omitted from the list), and will return '{error, {AppName, Reason}}' on a failure to allow users to rapidly know why the function failed. Note that no specific check is made for direct or indirect circular dependencies between applications, and these will make the function go in an infinite loop.
