2017-02-28zip: Don't crash when a zip file has an Unix extra headerBjörn Gustavsson
There is unfinished code in the zip module to handle the extra field in the central-directory header for each file. The code to extract an Unix extra subfield is incorrect and always causes a bad_unix_extra_field error. A further flaw in the code is that it expects that there is only a single subfield. Correcting the code for extracting extra subfields will not do any good, because the extracted data is ignored. In fact, not even the file times extracted from DOS file times are used for some reason. Therefore, don't correct the unfinished code. Remove it completely. (If needed, extending zip to use file times and to use the information in the extra field should be done in a major release, not in a maintenance release.) ERL-348
2017-02-27stdlib: Fix mime_decode/1 binary matching performanceJesse Stimpson
Symptom: Throughput of base64:mime_decode/1 significantly lower than base64:decode/1. Problem: tail_contains_more/2 prevents compiler from delaying creation of sub binaries. Solution: Restructure mime_decode_binary/2 to use binary matching best practices from the Efficiency Guide. See ERL-366

* bjorn/compiler/opt-binary-strings/OTP-14125: v3_core: Combine binary strings to larger integers
2017-02-27v3_core: Combine binary strings to larger integersBjörn Gustavsson
Binary construction that mixes long literal strings with variables will make Dialyzer slow. Example: <<"long string (thousand of characters)",T/binary>> The string literals in binary construction is translated to one binary segment per character; all those segments will slow down Dialyzer. We can speed up Dialyzer if we combine several characters (up to 256) to a signle segment in the binary. It will also slightly speed up the compiler. This optimization will make core listings file with binary strings harder to read, but they were not that easy to read before this change. ERL-308

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.
2017-02-21encode/decode: Include the stack trace in error returnsBjörn Gustavsson
The generated encode/2 and decode/2 functions can return cryptic error messages. Consider this ASN.1 spec: T DEFINITIONS AUTOMATIC TAGS ::= BEGIN S ::= SEQUENCE { b BOOLEAN, i INTEGER (1..100), j INTEGER (0..7), s OCTET STRING } END In OTP 19, the error terms will look like this: Eshell V8.2 (abort with ^G) 1> asn1ct:compile('T', [ber]). ok 2> rr('T'). ['S'] 3> 'T':encode('S', #'S'{}). {error,{asn1,{encode_boolean,undefined}}} 4> 'T':encode('S', #'S'{b=false}). {error,{asn1,{encode_integer,undefined}}} 5> 'T':encode('S', #'S'{b=false,i=7,j=0}). {error,{asn1,function_clause}} Some error terms are clearer than other. In the first error term, it is clear that the error refers to the 'b' field, since there is only one BOOLEAN in 'S'. The second error term could refer to either 'i' or 'j'. The last error term... well... in this case we can infer that it must refer to 's'. The easiest way to provide more information is to include the stack trace with line numbers in the error term: 3> 'T':encode('S', #'S'{b=false}). {error,{asn1,{{encode_integer,undefined}, [{'T',encode_integer,2,[{file,"T.erl"},{line,240}]}, {'T',enc_S,2,[{file,"T.erl"},{line,102}]}, {'T',encode,2,[{file,"T.erl"},{line,36}]}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {shell,exprs,7,[{file,"shell.erl"},{line,686}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,641}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,626}]}]}}} By looking at the generated Erlang code, we can see that encoding failed for 'i'. This is an compatible change. All that the documentation says is that the format of the error tuple is: {error,{asn1,Description}} With this change, Description is always a tuple: {ErrorDescription,StackTrace} Alternatives considered: Providing more information in the error term itself and make sure there can be no 'function_clause', 'badarg', or 'badmatch' exceptions. That would be possible, but it would require a lot of work and it would increase the size of the generated code and make it slower. Therefore, this solution was rejected.
