2010-08-11Fix faulty no_empty_run_queues assertionRickard Green
For a short period of time no_empty_run_queues may have been increased twice for a specific run queue. Two assertions did not take this into account.

* 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.
2010-08-07Align trailing message data for all types of structuresRickard Green
Alignment of trailing data in messages has been adjusted. This in order to be able to pass data of any type as trailing data in the future.

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.

2010-07-05term_to_binary use all 32 bits of INTEGER_EXTSverker Eriksson
Earlier, external format INTEGER_EXT was only produced for 28-bit signed integers. Now full 32-bit signed integers are produced as INTEGER_EXT to avoid the more costly SMALL_BIG_EXT format. Both old and new code can read 32-bit INTEGER_EXT. Also fixed integer encoding bugs in erl_interface erl_encode/erl_decode. (Thanks to Alexander Demidenko for reporting)

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.

2010-06-10{packet,http} allow empty response phraseSverker Eriksson
Packet type 'http' for erlang:deocode:packet and gen_tcp allow a response line with an empty phrase string, like "HTTP/1.1 200\r\n". Earlier, an empty phrase was only accepted if the status code was followed by space or tab, like "HTTP/1.1 200 \r\n".
2010-06-10fix open_port with many unset env varsSverker Eriksson
The erlang:open_port spawn and spawn_executable directives can include an {env, Env} directive to set up environment variables for the spawned process. Variables can be unset with {"NameOfVariable",false}. A bug in ert/emulator/sys/unix/sys.c could cause unset variables to not be unset. This would typically happen if there where more variables to be unset than there where already set variables in the destination evironment. Fix this problem for unix and add a new regression test for it to the port test suite. Windows does not seem to have the same problem.
2010-06-10allow open_port with env vars with trailing '=' on WindowsSverker Eriksson
Same problem that Steve Vinoski fixed for Unix. Similar fix done in erts/emulator/sys/win32/sys_env.c for Windows. Copy-paste from his commit-message: The erlang:open_port spawn and spawn_executable directives can include an {env, Env} directive to set up environment variables for the spawned process. A bug in ert/emulator/sys/unix/sys.c prevented applications from using {env, Env} to set an environment variable whose value ended with a '=' (equal sign) character; the code mistook the trailing equal sign as an indication that an environment variable was to be cleared from the environment of the spawned process. For example, passing an {env, Env} of {env, [{"foo", "bar="}]} would result in the code in sys.c seeing a string of the form "foo=bar=" The code would see the final '=' character and assume the directive wanted to clear a variable named "foo=bar" from the environment of the spawned process, rather than seeing it as a directive to set the environment variable "foo" to the value "bar=".
2010-06-09Add -erl_args flag to run_test programPeter Andersson
With -erl_args it's possible to divide the start options on the command line and this way specify explicitly which options are meant for Common Test, and which are meant for other OTP applications (or ERTS).

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.

Add an option that atomically tests for the existence of a file and creates it if the file does not exist, by passing the O_EXCL flag to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL varies across platforms and filesystems. {ok, Fd} = file:open("/tmp/foo", [write,exclusive]), {error, eexist} = file:open("/tmp/foo", [write,exclusive]).
