* ia/pr/678/OTP-1267: Revert "Add workaround for problems with s_client defaults" ssl: Add unit test case ssl: Ignore signature_algorithm (TLS 1.2 extension) sent to TLS 1.0/1 server
2015-04-22Revert "Add workaround for problems with s_client defaults"Ingela Anderton Andin
This reverts commit a3cf4eb4cdd2ce178d81b62faa9f47485fd82331. This workaround is no longer needed as the, TLS-1.2 extension, signature_algorithm is now correctly ignored by previous TLS versions.

By using environment variable HEART_KILL_SIGNAL, heart can now use a different signal to kill the old running Erlang. By default the signal is SIGKILL but SIGABRT may also be used by setting environment variable: HEART_KILL_SIGNAL=SIGABRT

2015-04-20zip: Suppress a dialyzer warning for an unmatched returnBjörn Gustavsson
A warning for an unmatched return was introduced in aaa7c917. The caller of openzip_close/1 ignores the return value, which could be an error tuple. In this situation, handling a fatal error, it is OK to ignore the return value; thus, we only need to make it explicit that we are ignoring the return value.
2015-04-20ssl: Ignore signature_algorithm (TLS 1.2 extension) sent to TLS 1.0/1 serverAndreas Schultz
pre TLS 1.2 server should ignore the signature_algorithms extension. The server code would attempt to select the signature/hash algorithm even when using TLS 1.0 or 1.1. Instead it should simply use the default algorithm on those versions.
2015-04-20erts/configure.in: handle more 'linux' spellingsMikael Pettersson
The configuration code which canonicalizes the operating system name into OPSYS requires Linux to be spelled 'linux' or 'Linux'. This is a problem in some build environments, e.g. RPM, which supply --build and --host using the longer 'linux-gnu' spelling. The effect is that OPSYS becomes 'noopsys' and some checks in erts/configure.in do not work as expected, e.g. the auto-enabling of HiPE may not happen. Fixed by matching on 'linux*' not just 'linux'. On ARM there are even longer variants such as 'linux-gnueabi' and 'linux-gnueabihf': these are also correctly mapped to 'linux' now.
2015-04-20Minor fixes to emacs erlang-modeSteve Vinoski
Fix "Unbalanced parentheses" error when indenting particular map constructs. Add new test cases for this fix. To prevent infinite looping when the programmer mistakenly enters incorrect syntax, detect cases where erlang-partial-parse fails to advance when called within a loop, and raise an "Illegal syntax" error.

2015-04-20public_key: Reject bad signatures as early as possibleIngela Anderton Andin
Erlang bitstring type only uses as many bits as required, and does not use padding to create complete bytes as ASN1 compact_bitstring did. crypto:verify/5 will now fail, for some incorrect signatures as it expects complete bytes which an incorrect signature may not have. Instead of catching the failing crypto function and then returning false we check the input and reject it right away.
2015-04-20public_key: Remove legacy switch compact_bit_stringIngela Anderton Andin
* E.I bitstrings will not be decode as {Unused, Binary}, they are now Erlang bitstrings. * Also the compact_bit_string implies the legacy_erlang_types switch - So removing the switch will also make OCTET STRING values be represented as binaries. - Undecoded open type will now be wrapped in a asn1_OPENTYPE tuple. We need to handle this in pubkey_pbe.erl, maybe this can be eliminated later by updating/refreshing ASN1-specs. This will change some values in records returned by the public_key API making this change a potentiall incompatibility.

2015-04-15Document the new {badmap,Term} and {badkey,Key} exceptionsBjörn Gustavsson
2015-04-15Raise more descriptive error messages for failed map operationsBjörn Gustavsson
According to EEP-43 for maps, a 'badmap' exception should be generated when an attempt is made to update non-map term such as: <<>>#{a=>42} That was not implemented in the OTP 17. José Valim suggested that we should take the opportunity to improve the errors coming from map operations: http://erlang.org/pipermail/erlang-questions/2015-February/083588.html This commit implement better errors from map operations similar to his suggestion. When a map update operation (Map#{...}) or a BIF that expects a map is given a non-map term, the exception will be: {badmap,Term} This kind of exception is similar to the {badfun,Term} exception from operations that expect a fun. When a map operation requires a key that is not present in a map, the following exception will be raised: {badkey,Key} José Valim suggested that the exception should be {badkey,Key,Map}. We decided not to do that because the map could potentially be huge and cause problems if the error propagated through links to other processes. For BIFs, it could be argued that the exceptions could be simply 'badmap' and 'badkey', because the bad map and bad key can be found in the argument list for the BIF in the stack backtrace. However, for the map update operation (Map#{...}), the bad map or bad key will not be included in the stack backtrace, so that information must be included in the exception reason itself. For consistency, the BIFs should raise the same exceptions as update operation. If more than one key is missing, it is undefined which of keys that will be reported in the {badkey,Key} exception.
