2019-03-01[socket|test] Moved old test modulesMicael Karlberg
Moved the old socket test modules into its own (temporary?) directory.

2018-12-14[socket-nif|test] Add a "global" loggerMicael Karlberg
Added a global logger that make it possible to log from the slave nodes (with "ease"). Also "fixed" the test case that failed on "older" linux (Ubuntu 14.04). For now we let it skip instead (we should really check the OS version). Also corrected a couple of (ping-pong) cases for which the buffer adjustments did not work. OTP-14831
2018-12-07[socket-nif|test] ttest improvementsMicael Karlberg
Added a ttest lib module for some common functions. Added a process (server handler and reader processes) stats printouts. So far only used by the server. There is still a "leak". Its a term leak. Some of the functions take a ref as argument (recv, send and accept for instance). This is stored internally, by way of a call to the enif_make_copy, in order to be used later in a select call. Its not "released" though, until the environment is released, which happens when the socket dtor callback function is called. Possible solution: We need to keep "temporary" environments (one for each of the queues), which we can clear (basically we need two, one that is currently used for new ref's and one for the old ref's).

2018-11-06Add a persistent term storageBjörn Gustavsson
Persistent terms are useful for storing Erlang terms that are never or infrequently updated. They have the following advantages: * Constant time access. A persistent term is not copied when it is looked up. The constant factor is lower than for ETS, and no locks are taken when looking up a term. * Persistent terms are not copied in garbage collections. * There is only ever one copy of a persistent term (until it is deleted). That makes them useful for storing configuration data that needs to be easily accessible by all processes. Persistent terms have the following drawbacks: * Updates are expensive. The hash table holding the keys for the persistent terms are updated whenever a persistent term is added, updated or deleted. * Updating or deleting a persistent term triggers a "global GC", which will schedule a heap scan of all processes to search the heap of all processes for the deleted term. If a process still holds a reference to the deleted term, the process will be garbage collected and the term copied to the heap of the process. This global GC can make the system less responsive for some time. Three BIFs (implemented in C in the emulator) is the entire interface to the persistent term functionality: * put(Key, Value) to store a persistent term. * get(Key) to look up a persistent term. * erase(Key) to delete a persistent term. There are also two additional BIFs to obtain information about persistent terms: * info() to return a map with information about persistent terms. * get() to return a list of a {Key,Value} tuples for all persistent terms. (The values are not copied.)

2017-06-03Remove obsolete old_scheduler_SUITEBjörn Gustavsson
old_scheduler_SUITE was written before the SMP emulator. It does not test anything that scheduler_SUITE does not test. Keeping it wastes time when running the emulator test suite, and does not help us find any bugs that scheduler_SUITE would find.

2017-02-20Ensure prim_eval:'receive' wont clobber def_arg_reg[0]Rickard Green
def_arg_reg[0] is used for storage of timeout instruction when a 'receive after' is executed. When a process was scheduled out inside prim_eval:'receive'/0 due to a function call, def_arg_reg[0] was overwritten due to storage of live registers. prim_eval:'receive'/2 now calls arg_reg_alloc/0 which bumps all reductions and then calls arg_reg_alloc/7 which will cause an allocation of a new arg_reg array since def_arg_reg only can hold 6 values. This ensures that the timeout instruction in def_arg_reg[0] used for the timeout wont be overwritten.

2017-01-12Support for dirty BIFsRickard Green
2016-07-06check_process_code: Sweep HiPE stack for literalsMagnus Lång
Because check_process_code neglected checking the HiPE stack for references to the literal area, such references would survive the purge and subsequent deletion of a module and its literal area. These dangling references would then cause incorrect behaviour or even hard crashes of the VM. By simply adding a scan of the HiPE stack to check_process_code and erts_garbage_collect_literals, this problem is fixed. In order to support full stack walks without deleting the graylimit trap, a new stack walking interface function, nstack_walk_init_sdesc_ignore_trap() was introduced.

2016-04-15erts: Extend process and port tracingLukas Larsson
This commit completes the tracing for processes so that all messages sent by a process (via nifs or otherwise) will be traced. The commit also adds tracing of all types of events from ports. When enabling tracing using erlang:trace, the 'all' flag now also enables tracing on all ports. OTP-13496
2016-04-15erts: Implement tracer modulesLukas Larsson
Add the possibility to use modules as trace data receivers. The functions in the module have to be nifs as otherwise complex trace probes will be very hard to handle (complex means trace probes for ports for example). This commit changes the way that the ptab->tracer field works from always being an immediate, to now be NIL if no tracer is present or else be the tuple {TracerModule, TracerState} where TracerModule is an atom that is later used to lookup the appropriate tracer callbacks to call and TracerState is just passed to the tracer callback. The default process and port tracers have been rewritten to use the new API. This commit also changes the order which trace messages are delivered to the potential tracer process. Any enif_send done in a tracer module may be delayed indefinitely because of lock order issues. If a message is delayed any other trace message send from that process is also delayed so that order is preserved for each traced entity. This means that for some trace events (i.e. send/receive) the events may come in an unintuitive order (receive before send) to the trace receiver. Timestamps are taken when the trace message is generated so trace messages from differented processes may arrive with the timestamp out of order. Both the erlang:trace and seq_trace:set_system_tracer accept the new tracer module tracers and also the backwards compatible arguments. OTP-10267

2016-02-25Allow erlang:finish_loading/1 to load more than one moduleBjörn Gustavsson
The BIFs prepare_loading/2 and finish_loading/1 have been designed to allow fast loading in parallel of many modules. Because of the complications with on_load functions, the initial implementation of finish_loading/1 only allowed a single element in the list of prepared modules. finish_loading/1 does not suspend other processes, but it must wait for all schedulers to pass a write barrier ("thread progress"). The time for all schedulers to pass the write barrier is highly variable, depending on what kind of code they are executing. Therefore, allowing finish_loading/1 to finish the loading for more than one module before passing the write barrier could potentially be much faster than calling finish_loading/1 multiple times. The test case many/1 run on my computer shows that with "heavy load", finish loading of 100 modules in parallel is almost 50 times faster than loading them sequentially. With "light load", the gain is still almost 10 times. Here follows an actual sample of the output from the test case on my computer (an 2012 iMac): Light load ========== Sequential: 22361 µs Parallel: 2586 µs Ratio: 9 Heavy load ========== Sequential: 254512 µs Parallel: 5246 µs Ratio: 49

2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.
