2017-03-22stdlib: Remove ets_SUITE:memory_check_summarySverker Eriksson
and let each test case fail, like it was before. Seems growing/shrinking meta tables was causing the sporadic failed memory checks.
2017-03-22erts: Replace meta_pid_to{_fixed}_tab with linked listsSverker Eriksson
from process psd through all owned/fixed tables. As meta_pid_to{_fixed}_tab maps to slot in meta_main_tab which is planned for destruction. In this commit we no longer seize table lock while freeing the table (free_table_cont) as it's not needed and makes the code a bit simpler. Any concurrent operation on the table will only access lock, owner and status and then bail out.

2017-03-16Don't allow module names with non-latin1 charactersBjörn Gustavsson
In OTP 20, all Unicode characters are allowed in atoms. However, we have decided that we will not allow non-latin1 characters in module names in OTP 20. This restriction may be lifted in a future major release of OTP. Enforce the restriction in erl_lint, so that it will be a compilation error to have a module name containing non-latin1 characters. That means that tools such as debugger, xref, dialyzer, syntax_tools, and so on, do not have to be modified to handle non-latin1 module names.

2017-02-22stdlib: Simplify error handling of the sofs moduleHans Bolinder
Atoms ('badarg', 'type_mismatch', &c) are used as errors instead of tuples containing the parameters. This makes it possible for the garbage collector to reclaim memory earlier. Since the exact format of error tuples is undocumented no release note is deemed necessary.

2017-02-21stdlib: Improve pretty-printing of terms with mapsHans Bolinder
As of committing this branch maps:fold/3 calls maps:to_list/1, which means that the time and memory needed for printing maps is not always proportional to the size of the generated deep list of characters.
2017-02-21filename: Add safe_relative_path/1Björn Gustavsson
Add safe_relative_path/1 to guard against directory traversal attacks. It either returns a shorter path without any ".." or "." components, or 'unsafe' if an ".." component would climb up above the root of the relative path. Here are a few examples: safe_relative_path("a/b/..") => "a" safe_relative_path("a/..") => "" safe_relative_path("a/../..") => unsafe safe_relative_path("/absolute/path") => unsafe The returned path can be used directly or combined with an absolute path using filename:join/2.

Update erl_tar to support PAX format (redux) OTP-14226
2017-02-16Update erl_tar to support PAX format, etc.Paul Schoenfelder
This commit introduces the following key changes: - Support for reading tar archives in formats currently in common use, such as v7, STAR, USTAR, PAX, and GNU tar's extensions to the STAR/USTAR format. - Support for writing PAX archives, only when necessary, using USTAR when possible for greater portability. These changes result in lifting of some prior restrictions: - Support for reading archives produced by modern tar implementations when other restrictions described below are present. - Support for filenames which exceed 100 bytes in length, or paths which exceed 255 bytes (see USTAR format specification for more details on this restriction). - Support for filenames of arbitrary length - Support for unicode metadata (the previous behaviour of erl_tar was actually violating the spec, by writing unicode-encoded data to fields which are defined to be 7-bit ASCII, even though this technically worked when using erl_tar at source and destination, it may not have worked with other tar utilities, and this implementation now conforms to the spec). - Support for uid/gid values which cannot be converted to octal integers.

Add a declaration to make it clear for tools that this module uses the gen_server behavior. While at it, also remove the totally unnecessary 'export_all' option.

In the future we will run xref to make sure that all functions that are exported are also used. Having internal exports only used for spawning or applying will mess with that.

There is no actual need to use export_all, since very few functions are actually called from the outside. While we are it, remove the unused functions in run_pcre_tests.erl.

2017-02-06Add shell shortcut for recompiling existing modulesRichard Carlsson
This extends the shell function c/1 and c/2 so that if the argument is a module name instead of a file name, it automatically locates the .beam file and the corresponding source file, and then recompiles the module using the same compiler options (plus any options passed to c/2). If compilation fails, the old beam file is preserved. Also adds c(Mod, Opts, Filter), where the Filter argument allows you to remove old compiler options before the new options are added.
2017-02-04Add filelib:find_file/2/3 and filelib:find_source/1/2/3Richard Carlsson
This moves, extends and exports functionality that previously existed only internally in filename:find_src/1/2, adding the ability to automatically substitute file suffixes and use different rules for different suffixes.

2017-02-02Make "~s" fail for Unicode atomsBjörn Gustavsson
26b59dfe67e introduced support for arbitrary Unicode characters in atoms. After that commit, it is possible to print any atom with a "~s" format string: 1> io:format("~s\n", ['спутник']). спутник Note that the same text as a string will fail: 2> io:format("~s\n", ["спутник"]). ** exception error: bad argument in function io:format/3 called as io:format(<0.53.0>,"~s\n", [[1089,1087,1091,1090,1085,1080,1082]]) Being more permissive for atoms is probably beneficial for io:format/2. However, for io_lib:format/2, the new behavior breaks this guarantee in the documentation for io_lib:format/2: If and only if the Unicode translation modifier is used in the format string (that is, ~ts or ~tc), the resulting list can contain characters beyond the ISO Latin-1 character range (that is, numbers > 255). The problem is that you can no longer be sure whether io_lib:format/2 will return an iolist that can be successfully passed to a port or iolist_to_binary/1. We see three solutions: 1. Keep the new behavior. That means that you can get non-iolist data when you use ~s for printing an atom, but a 'badarg' when printing Unicode strings. That is inconsistent, and it delays error detection if the result is passed to a port or iolist_to_binary/1. 2. Always allow Unicode characters for ~s. That would be incompatible, because ~s says that any binary is encoded in latin1, while ~ts says that any binary is encoded in UTF-8. To implement this solution, we could no longer support latin1 binaries; all binaries would have to be encoded in UTF-8. 3. Only allow ~s for atoms where all characters are less than 256. Require ~ts to print atoms such as 'спутник'. We reject solution 1 because it is slightly incompatible and is inconsistent. We reject solution 2 because it too incompatible. Therefore, this commit implements solution 3.
