2013-02-12Merge branch 'pan/unicode_filename_warnings'Björn Gustavsson
* pan/unicode_filename_warnings: Add file:list_dir_all/1 and file:read_link_all/1 prim_file: Add list_dir_all() and read_link_all() Teach prim_file:set_cwd() to avoid entering non-translatable directories Make prim_file skip invalid filenames in unicode mode 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
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.

2013-02-07BEAM loader: Handle element(Pos, not_a_tuple)Björn Gustavsson
The loader failed to load non-optimized BEAM code generated from: element(2, not_a_tuple) Commit ece4c17d2288a3161c995 introduced such code into core_fold_SUITE, leading to core_fold_no_opt_SUITE and core_fold_post_opt_SUITE failing to load.
2013-02-06erts: Increase length of well formed header names from {packet,http}Sverker Eriksson
To ease matching of unrecognized header field names we convert them from case insensitive to the format Sec-Websocket-Version with capital letters only first and after hyphens. Earlier only header names up to 20 characters were converted to this format due to internal buffer limitation. Raising this limit to 50 is a pragmatic solution for existing long header names such as Sec-Websocket-Version, while valid header names longer than 50 characters are not very probable.
2013-01-31compiler: Use the literal pool for floating point constantsBjörn Gustavsson
The BEAM loader will put floating point constants into the literal pools for the module, but it will not check for duplicates. We can do much better by having the compiler use the literal pool for floating point constants.

2013-01-28erts: Fix ASSERT crash in erts_try_seize_code_write_permissionSverker Eriksson
ASSERT(code_writing_process != c_p); The assert was actually harmless and could be removed as one solution. But I think it's better to keep it as a way to catch bugs that would otherwise lead to horrible deadlocks if a thread "forgets" to call erts_release_code_write_permission(). As a result erts_release_code_write_permission() must be called BEFORE resuming the suspended process.
