2017-02-28erts: Convert small sub-binaries to heap-binariesBjörn-Egil Dahlberg
In many cases sub-binaries costs more memory than converting them to heap-binaries. Sub-binaries also has a hidden cost of pinning larger binaries in memory. By converting binaries this cost is reduced. Byte aligned sub-binaries upto 24 bytes (64-bit) or 12 bytes (32-bit) are converted.

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.

2017-02-22[xmerl] Fix XML "well-formedness" bug i SAX parserLars Thorsen
Changed the XML Sax parser behaviour so it returns an error if there are something more in the file after the the matching document. If one using the xmerl_sax_parser:stream() a rest is allowed which then can be sent to a new call of xmerl_sax_parser:stream() to parse next document. This is done to be compliant with XML conformance tests.
2017-02-22[xmerl] Correct bug handling multiple documents on a streamLars Thorsen
Change how to interpret end of document to comply with Tim Brays comment on the standard. This makes it possible to handle more than one doc on a stream, the standard makes it impossible to know when the document is ended without waiting for the next document (and not always even that). Tim Brays comment about the trailing "Misc" rule: The fact that you're allowed some trailing junk after the root element, I decided (but unfortunately too late) is a real design error in XML. If I'm writing a network client, I'm probably going to close the link as soon as a I see the root element end-tag, and not depend on the other end closing it down properly. Furthermore, if I want to send a succession of XML documents over a network link, if I find a processing instruction after a root element, is it a trailer on the previous document, or part of the prolog of the next?
2017-02-21ssl: Always prefer AES over 3DESIngela Anderton Andin
AES256 was preferred over 3DES already, so this only makes sure AES128 is preferred over 3DES also. This changes the default but probably nobody will notice as a better algorithm will be chosen anyhow.

The size/1 callback was added as a non-optional callback in 42b8a29dbae1d626f32bc16dd81a129caf741138 but wasn't added to the documentation for the ssl_session_cache_api behavior. Signed-off-by: Steven Danna <[email protected]>
2017-02-21kernel: Fix hanging os:cmd race conditionLukas Larsson
If the port terminates before Port ! close is issued, there will be no 'closed' reply, so the old code would hang. As it turns out there is no way to figure out if a closed reply is supposed to come as that reply is sent after all links and monitors are triggered. So we have to use the synchronous port_close to close the port.
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.
