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.

2013-02-11Teach prim_file:set_cwd() to avoid entering non-translatable directoriesBjörn Gustavsson
We have decided that we don't want to deal with the compilations of prim_file:get_cwd() returning a binary when the current directory name cannot be translated losslessly to a list (i.e. when the run-time system was started with +fnu and the current directory name contains bytes that are not part of a valid UTF-8 sequence). Therefore, if prim_file:set_cwd() is given a binary as the pathname, we will need to check the binary to make sure it can be translated to a list. We will introduce a new BIF, called prim_file:is_translatable/1, which will check both filename encoding mode, and if it is one of Unicode modes, the binary as well. We don't need to do anything special if prim_file:set_cwd() is passed a list.
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.
2013-02-11prim_file: Refactor functions that return filenamesBjörn Gustavsson
2013-02-11prim_file: Refactor handling of responsesBjörn Gustavsson
Currently, the format of the return value from drv_command/3 is determined solely by the efile driver's response. In a future commit, we will need to produce different return values that also dependend on which function in prim_file that was called; thus, we will need some way to pass down some sort of state to drv_get_response/2. As a preparation for that, allow the third argument of drv_command/3 to be a fun. That also allows us to remove the convoluted special case handling of the list_dir operation.
2013-02-11prim_file: Always open non-file ports in binary modeBjörn Gustavsson
Ports for operations that did not directly operate on a file (such as listing the files in a directory) was always opened in a binary mode, but there was still code that supported such port opened in non-binary mode. Since we are about to update the code reading directories, and we don't want to bother we supporting non-binary ports, make sure that we force the use of binary mode.

2013-01-25Make arguments given with -s option to erl aware of file name encodingSiri Hansen
OTP-10702 Arguments to functions started with the -s option to erl were converted to atoms with list_to_atom(binary_to_list(Bin)) and thus were always seen as latin1 encoded. For other arguments to erl the conversion (to string) would take into account the file name translation mode (set with +fnl, +fnu or +fna switch to erl) and try to convert using unicode:characters_to_list/2. The reason behind this is that it must be possible to give paths and filenames on the command line and get the expected encoding. With the same reasoning, this commit changes the behaviour for arguments to functions started with the -s option to also take into account the file name translation mode. The arguments are now converted to atoms by list_to_atom(unicode:characters_to_list(Bin,file:native_name_encoding())
2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.

2013-01-21Text representation of a float formatted using given options.Serge Aleynikov
This BIF solves a problem of float_to_list/1 that doesn't allow specifying the number of digits after the decimal point when formatting floats. float_to_list(Float, Options) -> string() Float = float() Options = [Option] Option = {decimals, Decimals::0..249} | {scientific, Decimals::0..249} | compact Returns a string which corresponds to the text representation of a `Float` formatted using given options. When decimals option is specified the returned value will contain at most `Decimals` number of digits past the decimal point. When `compact` option is provided the trailing zeros at the end of the list are truncated (this option is only meaningful together with the `decimals` option). When `scientific` option is provided, the float will be formatted using scientific notation with `Decimals` digits of precision. If `Options` is `[]` the function behaves like `float_to_list/1`. When using `decimals` option and the number doesn't fit in the static internal buffer of 256 bytes the function throws `badarg`.
2013-01-09Add file:allocate/3 operationFilipe David Manana
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.

2012-08-16Allow mixed IPv4 and IPv6 addresses to sctp_bindxTomas Abrahamsson
Also allow mixed address families to bind, since the first address on a multihomed sctp socket must be bound with bind, while the rest are to be bound using sctp_bindx. At least Linux supports adding address of mixing families. Make inet_set_faddress function available also when HAVE_SCTP is not defined, since we use it to find an address for bind to be able to mix ipv4 and ipv6 addresses.
2012-08-14Make get/putenv and erlexec understand UnicodePatrik Nyblom
Putenv and getenv needs to convert to the proper environment strings in Unicode depending on platform and user settings for filename encoding. Also erlexec needs to pass environment strings in an appropriate way for kernel to pick up. All environment strings on the command line, as well as home directory, is now passed in UTF8 on windows and in whatever encoding you have on Unix, kernel tries to convert all parameters and environments from UTF8 before making strings.

2012-08-07Fix flattening of paths in erl_prim_loaderSiri Hansen
When correcting OTP-10071, a new error was introduced in erl_prim_loader. In order to improve ability to detect if a file was inside the primary archive, all paths were flattened - i.e. "." and ".." were removed. This implementation had some faults, and it did not take symlinks into account. This has been corrected.

2012-07-09Fix erl_prim_loader errors in handling of primary archiveSiri Hansen
The following errors have been corrected: * If primary archive was named "xxx", then a file in the same directory named "xxxyyy" would be interpreted as a file named yyy inside the archive. * erl_prim_loader did not correctly create and normalize absolute paths for primary archive and files inside it, so unless given with exact same path files inside the archive would not be found. E.g. if escript was started as /full/path/to/xxx then "./xxx/file" would not be found since erl_prim_loader would try to match /full/path/to/xxx with /full/path/to/./xxx. Same problem with ../. * Depending on how the primary archive was built, erl_prim_loader:list_dir/1 would sometimes return an empty string inside the file list. This was a virtual element representing the top directory of the archive. This has been removed. Thanks to Tuncer Ayaz and Shunichi Shinohara for reporting and co-authoring corrections.
