Copyright notices serve no useful purpose in vsn.mk files, and only complicate scripts that automatically update version numbers.

2010-08-19Remove binary overhead counter from ets objectsPatrik Nyblom
As the overhead counter got larger and never really was needed in ets objects, I removed them. A few stray comments of XXX:PaN type from halfword dev removed in the process.

* 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.

2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.

2010-07-07Fix ets:select hanging on ordered_set with empty list as key.Sverker Eriksson
erl_db_tree.c incorrectly used NIL (empty list) as "lastkey" to mark start of the iteration. A real NIL key could then cause a select or match iteration to be restarted over and over again if the last key before a trap happended to be NIL. Changed NIL to THE_NON_VALUE. Should be ok as the initial key value can never be put into any continuation tuple.

2010-06-09Correct warnings and errors for auto-imported bif clashesPatrik Nyblom
warn_unused_import works correctly (does not give warnings when overridden). Local call in guard gives its own error pointing out the local/imported function. Use of the phrase "overridden auto-imported bif" instead of "redefined auto-imported bif" in textual error messages.
2010-06-07Remove tid() from the predefined builtin types.Kostis Sagonas
Change erl_lint not to recognize this type as builtin and add a new erl_lint.beam version in bootstrap. Add an -opaque type declaration for this type in ets.erl and also declare this as an exported type. Use this type in file debugger/src/dbg_iload.erl in a spec. While at it, also clean up this later file a bit.
2010-06-07escript: Add more types to recordsKostis Sagonas
While at it, also do some cleanups.
2010-06-07Fix confusing dialyzer warnings for is_record/2 with illegal recordsBjörn Gustavsson
In commit 1858cb81391d2bce29b4b7620574ca60128cebf7, erl_expand_records started to optimize is_record/2 in guards by replacing it with pattern matching (if possible). Unfortunately, dialyzer will no longer see the code before the optimization, so any warnings produced in code such as: case ExprNotProducingRecord#rec{} of X when is_record(X, rec, N) -> ... will refer to the optimized code and not the source code, which is confusing for the user. Introduce the no_is_record_optimization option for turning off the optimization and use it in dialyzer. Reported-by: Kostis Sagonas

2010-06-03stdlib: Add declarations for exported typesKostis Sagonas
2010-06-03Add infrastructure for the -export_type() attributeKostis Sagonas
erl_lint has been updated so that it takes the new -export_type() attribute into account. This means: - do not complain about types which are defined but nowhere used in the module but exported to other modules - check that all types which are exported are indeed defined in the module - warn when there are multiple occurrences of exported types. In doing this change, I've also taken the liberty to introduce many types and specs for functions of this module and to do small cleanups here and there.
2010-06-03OTP-8665 epp bugHans Bolinder
The Erlang code preprocessor (epp) did not correctly handle premature end-of-input when defining macros. This bug, introduced in STDLIB 1.16, has been fixed.
2010-06-03Merge branch 'pan/otp_8579_autoimport_override' into devErlang/OTP
* origin/pan/otp_8579_autoimport_override: Update preloaded modules Update primary bootstrap Remove outcommented code from erl_lint Make port_command/3 auto-imported Remove (harmless) warnings about min/max in core applications Autoimport min/2 and max/2 Improve coverage of erl_int in testcases Change warning to error for nowarn_bif_clash compiler directive Add -compile({no_auto_import,[F/A]}) doc to compiler.xml Add some testcases to compiler to verify that overriding really happens Return nowarn_bif_clash functionality but with warning Teach erl_lint to better override BIFs with local functions and imports Teach compiler to override autoimport with import First prototype for local functions overriding autoimported OTP-8579 Local functions should override auto-imported Local and imported functions now override the autoimported BIFs when the names clash. The pre R14 behaviour was that autoimported BIFs would override local functions. To avoid that old programs change behaviour, the following will generate an error: Doing a call without explicit module name to a local function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Explicitly importing a function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Using any form of the old compiler directive nowarn_bif_clash If the BIF was added or autoimported in OTP R14A or later, overriding it with an import or a local function will only result in a warning, To resolve clashes, you can either use the explicit module name erlang to call the BIF, or you can remove the autoimport of that specific BIF by using the new compiler directive -compile({no_auto_import,[F/A]})., which makes all calls to the local or imported function without explicit module name pass without warnings or errors. The change makes it possible to add autoimported BIFs without breaking or silently changing old code in the future. However some current code ingeniously utilizing the old behaviour or the nowarn_bif_clash compiler directive, might need changing to be accepted by the compiler.
