* lukas/erts/sendfile_no_async_pool/OTP-11639: erts/kernel: sendfile no longer uses async threads
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.

* sv/file-osync/OTP-11498: Add sync option to file:open/2 Conflicts: erts/preloaded/ebin/prim_file.beam
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.

2013-02-20prim_file: Fix error return from prim_file:list_dir/1Björn Gustavsson
When the run-time system was started with +fnue, the error tuple indicating a non-translatable filename was added as a non-proper list tail inside an {ok,Files} term.
2013-02-18Fix broken prim_file:list_dir_all/1Björn Gustavsson
6d516de001dde82c02fe050db8e3aab47914fa90 added prim_file:list_dir_all/1. Unfortunately, only the first element in the list would be handled as intended.
2013-02-11prim_file: Add list_dir_all() and read_link_all()Björn Gustavsson
2013-02-11Make prim_file skip invalid filenames in unicode modePatrik Nyblom
The fix affects list_dir and read_link. Raw filenames are now never produced, just consumed even if +fnu or +fna is used on Linux etc. This also adds the options to get error return or error handler warning messages with +fn{u|a}{i|w|e} as an option to erl. This is still not documented and there needs to be other versions of read_dir and read_link to facilitate reading of all types of filenames and links. A check that we will not change to an invalid directory is also needed.

2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.
