2010-06-02OTP-8664 Erlang parser augmented with operators for integer typesHans Bolinder
Expressions evaluating to integers can now be used in types and function specifications where hitherto only integers were allowed ("Erlang_Integer").
2010-06-02Merge branch 'jv/autoimport-binary_to_term_2' into devErlang/OTP
* jv/autoimport-binary_to_term_2: Change binary_to_term/2 to be auto-imported OTP-8671 jv/autoimport-binary_to_term_2 Now, binary_to_term/2 is auto-imported. This will cause a compile warning if and only if a module has got a local function with that name.

Combine a sequence of chained is_eq_exact instructions into a select_val instruction.
2010-06-02Evaluate is_record/3 at compile-time using type informationBjörn Gustavsson
2010-06-02Evaluate element/2 at compile-time using type informationBjörn Gustavsson
The erl_expand_records compiler pass translates the following code: h(X) when X#r1.a =:= 1 -> ok. to (essentially): h({r1,V1,V2}=X) when element(2, X) =:= 1 -> ok. Since the guard can only be executed when the pattern matching has succeeded, we know that the second element in the tuple X must have been bound to V2. Thus we can eliminate the call to element/2 like this: h({r1,V1,V2}=X) when V1 =:= 1 -> ok.
2010-06-02erl_expand_records: Replace is_record() with matchingBjörn Gustavsson
The compiler currently generates better code for: f(#r1{}) -> r1; f(#r2{}) -> r2; f(#r3{}) -> r3. than for: g(X) when is_record(X, r1) -> r1; g(X) when is_record(X, r2) -> r2; g(X) when is_record(X, r3) -> r3. The compiler generates good code for pattern matching (as in f/1), but in g/1 there are no patterns to match, and the clause to be executed must be chosen by evaluating the guards sequentially until one succeeds. Make the compiler generate better code by replacing calls to is_record() with matching in the function head (basically, g/1 will automatically be rewritten to do pattern matching as in f/1). Note that this rewrite will also benefit code such as: h(X) when X#r1.a =:= 1 -> ok. because it would have been rewritten to: h(X) when (is_record(X, r1, 3) orelse fail) and (element(2, X) =:= 1) -> ok. which in turn will be rewritten to: h({r1,_,_}=X) when (true orelse fail) and (element(2, X) =:= 1) -> ok. (That will be further simplified in later compiler passes.)
2010-06-02Merge branch 'rn/resolver-leaking-ports' into devErlang/OTP
* rn/resolver-leaking-ports: Resolver: make inet_dns decode ugly truncated reply Resolver: stop inet_res leaking ports OTP-8652 inet_res leaking ports The kernel DNS resolver was leaking one or two ports if the DNS reply could not be parsed or if the resolver(s) caused noconnection type errors. Bug now fixed. A DNS specification borderline truncated reply triggering the port leakage bug has also been fixed.
2010-06-01Add catch all handle_call to net_kernelAntonio SJ Musumeci
Of the core networking apps only net_kernel fails to have a catchall for unknown gen_server:call messages causing it to exit and eventually bring down kernal_sup and beam if it had not been manually started. For stability and consistancy it has been altered to include a catchall which does not reply.
2010-06-01Merge branch 'dgud/emacs-catch-improvements' into devErlang/OTP
* dgud/emacs-catch-improvements: Improved indentation of old catch. Added more type highlighting and fixed record indentation with types.

Added cross configuration file for mips-linux. (Thanks to Matthias Lang for the configuration)
2010-06-01OTP-8662 Fix ethr_rwmutex_tryrlockRickard Green
ethr_rwmutex_tryrlock() acquired and refused to acquire a lock with inverted logic. The lock was however never acquired in a thread unsafe manner. (Thanks to JR Zhang for noting this issue)
2010-06-01OTP-8661 Enable writer preferred pthread read/write locks on LinuxRickard Green
Writer preferred pthread read/write locks has been enabled on Linux.
2010-06-01OTP-8660 Increase atomic fallback locksRickard Green
The number of spinlocks used when implementing atomic fall-backs when no native atomic implementation is available has been increased from 16 to 1024.
2010-06-01OTP-8612 Fix potential premature destruction of port locksRickard Green
Port locks could be prematurely destroyed.
2010-06-01OTP-8659 Add ethread support for gcc atomicsRickard Green
Support for using gcc's built-in functions for atomic memory access has been added. This functionallity will be used if available and no other native atomic implementation in ERTS is available.
2010-06-01OTP-8658 Add missing memory barriers in erts_poll()Rickard Green
Missing memory barriers in erts_poll() could cause the runtime system to hang indefinitely.

* bg/dist_utils: dist_utils: Eliminate crash when list_to_existing_atom/1 fails
2010-06-01Improved indentation of old catch.Dan Gudmundsson
An example that didn't work previously. case Foo of {ok, X} -> ok; _ -> catch file:close(FD) end.
2010-06-01Added more type highlighting and fixed record indentation with types.Dan Gudmundsson
Type highlighting reported by Jay Nelson non_neg_integer() will highlight purple but pos_integer() does not. Closing record indentation problem reported by Maxim Treskin: -record(state, { sequence_number = 1 :: integer() }).

2010-06-01erlang-flymake: Make the syntax check command configurableKlas Johansson
2010-06-01erlang-flymake: By default pass <app>/include and <app>/ebin to compilerKlas Johansson
Hopefully this covers at least some of the common cases and makes the flymake support more usable as is. The purpose of including the ebin directory is to support things like behaviours and parse transforms.

2010-06-01Resolver: make inet_dns decode ugly truncated replyRaimo Niskanen
Bugfix: a DNS reply with the truncation bit set containing misleading section length (i.e header claimed length greater than what was actually in the reply section) in the header caused decode error in inet_dns.
2010-06-01Resolver: stop inet_res leaking portsRaimo Niskanen
Bugfix: when all nameservers return a reply causing decode errors or when errors enetunreach or econnrefused occured while contacting them, one or two UDP ports was leaked i.e left open and forgotten.
2010-06-01Remove unsupported erlang:blocking_read_file/1Björn Gustavsson
This BIF was only used by the now broken SAE support.
2010-06-01Remove stray SAE supportBjörn Gustavsson
The experimental Standalone Erlang (SAE) support based on Joe Armstrong's work has long been broken. Remove the remaining code and Makefile rules.
2010-06-01dist_utils: Eliminate crash when list_to_existing_atom/1 failsBjörn Gustavsson
In the following scenario list_to_existing_atom/1 may crash during handshake: Start a node in one window: erl -sname adam@localhost Start another node in another window: erl -sname bertil In this node, ping the first node (use the actual hostname in the command): net:ping(adam@hostname). There will be an error report similar to: =ERROR REPORT==== 27-May-2010::15:03:14 === Error in process <0.40.0> on node 'bertil@hostname' with exit value: {badarg,[{erlang,list_to_existing_atom, ["adam@localhost"]},{dist_util,recv_challenge,1},{dist_util,handshake_we_started,1}]} Eliminate the crash and the error report by catching the call to list_to_existing_atom/1 and do a clean shutdown if it fails.

2010-05-28Merge branch 'sv/socket-error-portability' into devErlang/OTP
* sv/socket-error-portability: inet_drv.c: Remove red herring use macro to portably test for socket system call errors OTP-8654 sv/socket-error-portability On some combination of Montavista Linux on Cavium Octeon processors, some socket-related system calls returned other numbers than -1 for errors. This caused a core dump in inet_drv.c. Now the code works around this problem.
