2010-08-30Implement automatic detection of CPU topology on WindowsRickard Green
The CPU topology is now automatically detected on Windows systems with less than 33 logical processors. The runtime system will now, also on Windows, by default bind schedulers to logical processors using the 'default_bind' bind type if the amount of schedulers is at least equal to the amount of logical processors configured, binding of schedulers is supported, and a CPU topology is available at startup.

2010-08-18Make it possible to reread and update detected CPU informationRickard Green
Calling erlang:system_info/1 with the new argument 'update_cpu_info' will make the runtime system reread and update the internally stored CPU information. For more information see the documentation of erlang:system_info(update_cpu_info).
2010-08-17erts: Remove broken elib_mallocBjörn Gustavsson
elib_malloc is an alternate memory allocator that is no longer possible to build.
2010-08-10Merge branch 'rickard/ethread-rewrite/OTP-8544' into devRickard Green
* rickard/ethread-rewrite/OTP-8544: Rewrite ethread library
2010-08-10Rewrite ethread libraryRickard Green
Large parts of the ethread library have been rewritten. The ethread library is an Erlang runtime system internal, portable thread library used by the runtime system itself. Most notable improvement is a reader optimized rwlock implementation which dramatically improve the performance of read-lock/read-unlock operations on multi processor systems by avoiding ping-ponging of the rwlock cache lines. The reader optimized rwlock implementation is used by miscellaneous rwlocks in the runtime system that are known to be read-locked frequently, and can be enabled on ETS tables by passing the `{read_concurrency, true}' option upon table creation. See the documentation of `ets:new/2' for more information. The ethread library can now also use the libatomic_ops library for atomic memory accesses. This makes it possible for the Erlang runtime system to utilize optimized atomic operations on more platforms than before. Use the `--with-libatomic_ops=PATH' configure command line argument when specifying where the libatomic_ops installation is located. The libatomic_ops library can be downloaded from: http://www.hpl.hp.com/research/linux/atomic_ops/ The changed API of the ethread library has also caused modifications in the Erlang runtime system. Preparations for the to come "delayed deallocation" feature has also been done since it depends on the ethread library. Note: When building for x86, the ethread library will now use instructions that first appeared on the pentium 4 processor. If you want the runtime system to be compatible with older processors (back to 486) you need to pass the `--enable-ethread-pre-pentium4-compatibility' configure command line argument when configuring the system.

Final merge of all unexpected differences from dev to release.
2010-06-14OTP-8710 Fix emulator crash caused by setting CPU topologyRickard Green
A user defined CPU topology set via a call to <seealso marker="erlang#system_flag_cpu_topology">erlang:system_flag(cpu_topology, CPUTopology)</seealso> was not properly verified, and could in worst case cause an emulator crash. The emulator crash could only occur when a user defined CPU topology already existed and was redefined.

2010-06-09Merge branch 'pan/otp_8669_doc_autoimported' into devErlang/OTP
* pan/otp_8669_doc_autoimported: Change documentation for erlang:min/2,max/2 and port_command/3 to OTP-8669 erlang:min, erlang:max and erlang:port_command/3 autoimported The recently added BIFs erlang:min/2, erlang:max/2 and erlang:port_command/3 are now auto-imported (as they were originally intended to be). Due to the recent compiler change (OTP-8579), the only impact on old code defining it's own min/2, max/2 or port_command/3 functions will be a warning, the local functions will still be used. The warning can be removed by using -compile({no_auto_import,[min/2,max/2,port_command/3]}). in the source file.

2010-06-03OTP-8666 Enable automatic binding of schedulers when possibleRickard Green
The runtime system will by default bind schedulers to logical processors using the default_bind bind type if the amount of schedulers are at least equal to the amount of logical processors configured, binding of schedulers is supported, and a CPU topology is available at startup. NOTE: If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. If this is the case you, are are advised to unbind the schedulers using the <seealso marker="erl#+sbt">+sbtu</seealso> command line argument, or by invoking <seealso marker="erlang#system_flag_scheduler_bind_type">erlang:system_flag(schedule r_bind_type, unbound)</seealso>.

2010-06-03Merge branch 'pan/otp_8086_ms_grammar' into devErlang/OTP
* pan/otp_8086_ms_grammar: Add match_specification grammar documentation specifically for ets OTP-8086 Grammar for match specification describes tracing only The grammar for match specifications in ERTS users guide only described the tracing dialect of match specifications. An informal grammar for the ETS dialect is added.

* 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.
2010-06-02Add match_specification grammar documentation specifically for etsPatrik Nyblom
2010-05-31Add erlang:nif_error/1,2Björn Gustavsson
A stub function that is supposed to be replaced by a NIF usually calls erlang:error/1 to cause an exception if the NIF library is not loaded. For example: foo() -> erlang:error(nif_not_loaded). The problem is that although erlang:error/1 will normally never be called, Dialyzer will think that any call to the function will fail and thus generate false warnings. Adding a spec for the function will not help because Dialyzer will not believe the spec. Add erlang:nif_error/1,2 that work exactly like erlang:error/1,2. Define the return types for both BIFs to be t_any(). erlang:nif_error is used like this: -spec foo() -> binary(). foo() -> erlang:nif_error(nif_not_loaded). (The -spec is optional but highly recommended, since Dialyzer otherwise has no chance to figure out the types.)
2010-05-24erl_nif: add make_atom_len, make_existing_atom_len and make_string_lenTuncer Ayaz
Add new NIF API functions - enif_make_atom_len - enif_make_existing_atom_len - enif_make_string_len These are basically the same as enif_make_atom, enif_make_existing_atom and enif_make_string except that the new functions require a length parameter instead of a null-terminated C-string.

2010-05-24Change binary_to_term/2 to be auto-importedJayson Vantuyl
While binary_to_term/2 was added in R13B04, it wasn't auto-imported. This conformed to longstanding policy of not changing auto-imports between major versions. This patch contains changes to auto-import binary_to_term/2 to coincide with the release of R14.
