The recommended type for filenames is a list of characters (which
may be Unicode characters greater than 255). Change the
file:filename() to reflect that.
For the filename module we still need a type that can be either
a string or a binary, so we need to introduce the type
file:filename_all().

prim_file: Refactor functions that return filenames
prim_file: Refactor handling of responses
prim_file: Always open non-file ports in binary mode
Test that list_dir("non-existing-dir") fails with the correct error

This operation allows pre-allocation of space for files.
It succeeds only on systems that support such operation.
The POSIX standard defines the optional system call
posix_fallocate() to implement this feature. However,
some systems implement more specific functions to
accomplish the same operation.
On Linux, if the more specific function fallocate() is
implemented, it is used instead of posix_fallocate(),
falling back to posix_fallocate() if the fallocate()
call failed (it's only supported for the ext4, ocfs2,
xfs and btrfs file systems at the moment).
On Mac OS X it uses the specific fcntl() operation
F_PREALLOCATE, falling back to posix_fallocate() if
it's available (at the moment Mac OS X doesn't provide
posix_fallocate()).
On any other UNIX system, it uses posix_fallocate() if it's
available. Any other system not providing this system call
or any function to pre-allocate space for files, this operation
always fails with the ENOTSUP POSIX error.

Expect modifications, additions and corrections.
There is a kludge in file_io_server and
erl_scan:continuation_location() that's not so pleasing.

The mode() type is used in path_open and copy, two functions that
do _not_ accept the ram option (or is at least not supposed to),
why I moved the option 'ram' from the type down to the spec for
open itself. That also makes the option visible directly under open/2
in the documentation.

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.

Since the API for headers/trailers seem to be very awkward to
work with when using non-blocking io the feature is dropped
for now. See unix_efile.c for more details.

Since sendfile could in theory be used to send to any type
of file descriptor in *nix, it is a better fit to have it
in file.
|
|
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.
|
|
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."
|
|
Calling file:change_time/2,3 with an invalid date tuple
(e.g file:change_time("file.txt", {undefined, undefined}))
will cause file_server_2 to crash.
error_logger will shutdown and the whole VM will stop.
Change behavior to validate given dates on system boundaries.
(i.e before issuing a server call).
|
|
In the location information tables in the run-time system, source
filenames that are the same as the module name plus ".erl" extension
are not stored explicitly, thus saving memory.
To take advantage of that optimization, avoid complicating the names of
files in the current working directory; specifically, make sure that
"./" is not prepended to the name.

Change type for second parameter from binary() to iodata(), since the

* ks/erl_bif_types-cleanup/OTP-8961:
Fix type information of 'file' and 'code' modules
Conflicts:

Dialyzer for a long time now has had hard-coded type information about
key functions of the 'file' and 'code' modules in 'erl_bif_types'.
Some of this information was not up-to-date according to the published
Erlang/OTP documentation, while some other part contained small errors.
Now that specs are available, this information should be moved to the
corresponding files, not be hard-coded in erl_bif_types.
This change takes out all information for the 'file' module and fixes
some small errors in type information for the 'code' module.
|

Although the {encoding, encoding()} set of options is documented in
the manual page of the 'file' module, they do not appear in the Mode
description on that page nor in the mode() type declaration.
The patch adds this information in both the code of the module and
the documentation of the module.
To avoid duplication, the declaration of the encoding() type is added
to the 'unicode' module where it most probably belongs.
While at it, added a proper declaration for posix(), took out the
now superfluous information about the types of file:open/2 from the
erl_bif_types module, and corrected the return type of file:open/2
so that it corresponds to the published documentation.
