Almost all uses of the 'long' datatype is removed from VM and tests Emulator test now runs w/o drivers crashing Nasty abs bug fixed in VM as well as type errors in allocator debug functions Still one allocator test that fails, domain knowledge is needed to fix that.

2011-12-02Mend the non-SMP emulatorBjörn Gustavsson
Commit 8781932b3b8769b6f208ac7c00471122ec7dd055 broke erlang:system_info(system_version) in the non-SMP emulator so that it would typically dump core. "rq:%d" was removed from the format string for erts_printf(), but the corresponding argument in the argument list was not removed, which ultimately caused "kernel-poll:%s" to be passed an integer (typically 0).

2011-12-01Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topologyRickard Green
The use of erlang:system_flag(scheduler_bind_type, _) and erlang:system_flag(cpu_topology, _) have been deprecated and scheduled for removal in erts-5.10/OTP-R16. For more information see the documentation of erlang:system_flag/2.
2011-12-01Remove common run-queue in SMP caseRickard Green
The common run-queue implementation is removed since it is unused, untested, undocumented, unsupported, and only complicates the code. A spinlock used by the run-queue management sometimes got heavily contended. This code has now been rewritten, and the spinlock has been removed.
2011-12-01Fix scheduler suspend bugRickard Green
Calls to erlang:system_flag(schedulers_online, N) and/or erlang:system_flag(multi_scheduling, block|unblock) could cause internal data used by this functionality to get into an inconsistent state. When this happened various problems occurred. This bug was quite hard to trigger, so hopefully no-one has been effected by it.

2011-11-29erl_process.c: Remove the redundant variable 'processes_busy'Björn Gustavsson
There is a static variable called 'processes_busy' in erl_process.c, which will be incremented but never used. To confuse things, there is also a global variable with the same name, but it it is only defined and used if BM_COUNTERS is defined. In erl_process.c, the global version of 'processes_busy' will be seen and incremented if BM_COUNTERS is defined. Remove the static version of 'processes_busy' in erl_process.c, but keep the global version if BM_COUNTERS is defined. Noticed-by: Jovi Zhang

2011-11-26beam_load.c: Add init_iff_file() for verifying the IFF headerBjörn Gustavsson
Add init_iff_file() for verifying the IFF header. Also let it handle compressed BEAM files so that it will be done in one place. That means that code:get_chunk/2 and code:module_md5/1 will now support compressed BEAM files.

2011-11-26beam_load.c: Optimize code:get_chunk/2Björn Gustavsson
The undocumented code:get_chunk/2 BIF is supposed to be a fast way to extract a chunk from a BEAM file when loading native code. In practice, it might not have been faster because it happened to calculate an MD5 checksum for the chunk it extracted because it shared the scan_iff_file() function with the erlang:load_module/2 BIF. Split scan_iff_file() into scan_iff_file() and verify_chunks(), so that the unnecessary MD5 calculation can be avoided.
2011-11-26beam_load.c: Eliminate memory leak in code:make_stub_module/3Björn Gustavsson
code:make_stub_module/3 leaked memory if given either a corrupt BEAM file, or a compressed BEAM file and an error occurred, or a binary not aligned on byte boundaries.
2011-11-25Fix clang linking problemBjörn Gustavsson
Inlining was not done in a portable way. clang follows the C99 semantics for inlining ('inline' essentially implies 'static' in C99, but not in GCC), so bp_sched2ix() was not visible outside beam_bp.c. Since the function need to be used from more than one source file, put the function definition in the beam_bp.h header file. Also, give it an 'erts_' prefix since it is globally visible.

2011-11-18Use unbound schedulers as defaultRickard Green
As of ERTS version 5.9 (OTP-R15B) the runtime system will by default not bind schedulers to logical processors. 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. In some cases this performance penalty might be severe. Due to this, we change the default so that the user must make an active decision in order to bind schedulers.

2011-11-17external.c: Remove the option to create over-sized heap binariesBjörn Gustavsson
Since refc binaries are now supported in literal pools, there is no longer any need to allow the creation of over-sized heap binaries.
2011-11-17Allow refc binaries in literal poolsBjörn Gustavsson
To simplify the implementation of literal pools (constant pools) for the R12 release, a shortcut was taken regarding binaries -- all binaries would be stored as heap binaries regardless of size. To allow a module containing literals to be unloaded, literal terms are copied when sent to another process. That means that huge literal binaries will also be copied if they are sent to another process, which could be surprising. Another problem is that the arity field in the header for the heap object may not be wide enough to handle big binaries. Therefore, bite the bullet and allow refc binaries to be stored in literal pools. In short, the following need to be changed: * Each loaded module needs a MSO list, linking all refc binaries in the literal pool. * When check_process_code/2 copies literals to a process heap, it must link each referenced binary into the MSO list for the process and increment the reference counter for the binary. * purge_module/1 must decrement the reference counter for each refc binary in the literal pool.

2011-11-17BEAM loader: Don't stop other schedulers until truly neededBjörn Gustavsson
The erlang:module_load/2 BIF will stop all other schedulers before it starts to process the BEAM file. That is not a problem when starting the Erlang/OTP system, since the start-up is mostly sequential. It is a problem, however, when big BEAM files are loaded in an already running system. After the refactoring in the previous commits, we can now do most of the processing of the BEAM file before we stop the other schedulers, so that we can minimize the time when only one scheduler will be running.

2011-11-14BEAM loader: Refactor code loading into separate functionsBjörn Gustavsson
Break apart code loading into the three functions: erts_alloc_loader_state() erts_prepare_loading() erts_finish_loading() The erts_alloc_loader_state() and erts_prepare_loading() can be executed with all schedulers running. Only erts_finish_loading() needs to be run in a single-scheduling system.
2011-11-14beam_load.c: Factor out cleaning up of the loader state into free_state()Björn Gustavsson
2011-11-14BEAM loader: Clean up handling of error reasonsBjörn Gustavsson
There is no reason to have erts_load_module() return integer values, only to have the caller convert the values to atoms. Return the appropriate atom directly from the place where the error is generated instead. Return NIL if the module was successfully loaded.
