2010-01-19Merge branch 'bg/compiler-beam_validator' into ccase/r13b04_devErlang/OTP
* bg/compiler-beam_validator: beam_validator: fix incorrect assumptions about GC guard BIFs OTP-8378 In rare circumstances when using garbaging collecting guard BIFs, the validation pass (beam_validator) would signal that the code was unsafe, when it in fact was correct. (Thanks to Kiran Khaladkar.)
2010-01-19Merge branch 'fh/common_test-includes' into ccase/r13b04_devErlang/OTP
* fh/common_test-includes: make it possible to include ct.hrl using include_lib Include test_servers's include files in the bootstrap OTP-8379 It is now possible to include the ct.hrl using the -include_lib directive. (Thanks to Fred Hebert.)
2010-01-18Fix annoying failing statistics_SUITE test casesBjörn Gustavsson
In an SMP emulator, two of the test cases in statistics_SUITE frequently fail. Remove the runtime_zero_update/1 test case, because you can't really expect an SMP emulator not to spend any CPU time at all even if no Erlang process is active. Adjust the runtime_update/1 test case to not fail if the measured times are note close enough. It will still fail if statistics(runtime) would fail or return the wrong type.
2010-01-17make it possible to include ct.hrl using include_libFred T-H
It is major annoyance that ct.hrl cannot be included using "-include_lib". The problem is that ct.hrl in turn includes the test_server include files using "-include". Fix it by using "-include_lib" in ct.hrl.

2010-01-15Include test_servers's include files in the bootstrapBjörn Gustavsson
To make it possible to use -include_lib to include the include files for test_server, those include files must be included in the bootstrap directory.
2010-01-15Merge branch 'egil/binary-gc' into ccase/r13b04_devErlang/OTP
* egil/binary-gc: Add documentation for binary heap size settings. Add tracing capabilities for binary virtual heap Add min heap size start options to beam and erl Improve binary garbage collection OTP-8370 The default settings for garbage collection of binaries has been adjusted to be less aggressive than in R13B03. It is now also possible configure the settings for binary GC. See the documentation for spawn_opt/2-5, erlang:system_info/1, erlang:system_flag/2, process_flag/2-3, erlang:trace/3, and the documenation for erl for the new command line options +hms and +hmbs.
2010-01-15beam_validator: fix incorrect assumptions about GC guard BIFsBjörn Gustavsson
The beam_validator pass incorrectly assumes that a GC guard BIF (such as length/1) may first do a garbage collection and then fail. That assumption is not correct (guards BIF only do garbage collection when it is known that the BIF call will succeed), and will cause the compiler to reject valid programs. Modify the beam_validator to assume that if the branch is taken for a gc_bif instruction, all registers are unchanged and no garbage collection has occurred. Also add a comment in the emulator about that assumption.

2010-01-13Add documentation for binary heap size settings.Björn-Egil Dahlberg
Documentation of min_heap_size and min_bin_vheap size for: * spawn_opt/2, spawn_opt/3, spawn_opt/4, spawn_opt/5 * erlang:system_flag/2 * erlang:system_info/1 * process_flag/2 * process_info/2 * erlang:trace/3 Documentation for the new beam start arguments: +hms Size, Default minimum heap size for processes. +hmbs Size, Default minimum binary virtual heap size.
2010-01-13Add tracing capabilities for binary virtual heapBjörn-Egil Dahlberg
2010-01-13Add min heap size start options to beam and erlBjörn-Egil Dahlberg
The erl (and beam) start arguments are extended with the following options: * +hms Size, sets the default minimum heap size for processes. * +hmbs Size, sets the default minimum binary virtual heap size for processes. The previous +h Size argument can still be used for backward compatibility purposes.
2010-01-13Improve binary garbage collectionBjörn-Egil Dahlberg
The garbage collector in r13b03 is too aggressive in some cases. This commit raises the level of default initial allowed binary garbage (virtual heap for binaries) before collecting from 233 words to 46368 words (181 kB on 32-bit). A new option, min_bin_vheap_size, has been added to spawn_opt, system_flag and process_flag can be used to change the default values. The option can also be used with system_info and process_info to inspect the values. For symmetry the option min_heap_size has been added to the above functions where it was previously missing. Add testcases for min_bin_vheap_size and min_heap_size for functions process_flag/2, process_info/2, system_info/2 and spawn_opt/2.

2010-01-12Support updating preloaded files in a git repositoryBjörn Gustavsson
The commands in otp_build for updating the checked-in preloaded modules only works in ClearCase. Add support updating the preloaded files in a git repository as well. Check the $version_controller variable so that we can have "otp_build update_preloaded" do different things depending on whether it is run in a ClearCase view or a git repository. When run in a git repository, "otp_build update_preloaded" will update and commit the preloaded modules (to undo the updating of the preloaded modules, do "git reset --hard HEAD^"). Update the usage text to only show the commands relevant to the kind of VCS it is being run in.
2010-01-12Support updating the primary bootstrap in a git repositoryBjörn Gustavsson
The commands in otp_build for updating the checked-in primary bootstrap only works in ClearCase. Add support updating the bootstrap in a git repository as well. Check the $version_controller variable so that we can have "otp_build update_primary" do different things depending on whether it is run in a ClearCase view or a git repository.

Update the usage text to only show the commands relevant to the kind of VCS it is being run in.
2010-01-12Determine which VCS is being usedBjörn Gustavsson
We want to add the ability for otp_build to determine which version control system (VCS) is being used, so that the commands for updating the primary bootstrap and pre-loaded modules can be updated to do different things depending on the VCS. In the beginning of the otp_build script, set the variable "version_controller" to either "none" (for no VCS), "git", or "clearcase".
2010-01-12stdlib makefile: Add explicit ruleBjörn Gustavsson
When building a primary bootstrap in a git repository, the file bootstrap/lib/stdlib/egen/erl_parse.erl would not get updated. With clearmake, this file is updated. Adding an explicit rule for the file make it it work with GNU Make. While at it, remove an out-commented rule.

2010-01-08document ErtsExternalDist flags and CON_ID maskJayson Vantuyl
In the ErtsExternalDist structure, the flags field holds a combination of flags (tagged into the high bits) and the connection ID (in the low bits). This wasn't clearing indicated anywhere. This patch adds a comment before the flags and mask that indicates their use and relation to each other. This will help guide people through the code and reduce the likelihood that someone will add a flag without adjusting the mask.
2010-01-08add options to binary_to_termJayson Vantuyl
term_to_binary and binary_to_term are powerful tools that can be used easily in lieu of a custom binary network protocol. Unfortunately, carefully crafted data can be used to exhaust the memory in an Erlang node by merely attempting to decode binaries. This makes it unsafe to receive data from untrusted sources. This is possible because binary_to_term/1 will allocate new atoms and new external function references. These data structures are not garbage collected. This patch implements the new form of binary_to_term that takes a list of options, and a simple option called 'safe'. If specified, this option will cause decoding to fail with a badarg error if an atom or external function reference would be allocated. In the general case, it will happily decode any Erlang term other than those containing new atoms or new external function references. However, fun, pid, and ref data types can embed atoms. They might fail to decode if one of these embedded atoms is new to the node. This may be an issue if encoded binaries are transferred between nodes or persisted between invocations of Erlang.

2009-12-22Handle "extra" field according to specs in ALIVE2_REQ and PORT2_RESP.Klas Johansson
Don't let the length field pollute the value of the "extra" field in ALIVE2_REQ. Extra was read, starting at the second byte of the two byte length field, which meant that it was included in the result and the last byte of the value was skipped: if "extra" is <<1, 2>>, return <<0, 2, 1, 2>> not <<0, 2, 2, 1>> Increment the offset correctly when sending PORT2_RESP, in order to make sure the "extra" field won't be truncated: if "extra" is <<>>, return <<0, 0>> not <<0>> if "extra" is <<1, 2>>, return <<0, 2, 1, 2>> not <<0, 2, 1>> Allow null characters in "extra".
2009-12-21Order version fields in documentation for ALIVE2_REQ correctlyKlas Johansson
Place HighestVersion before LowestVersion, since that is what the source code does (erl_epmd.erl and epmd_srv.c).

This is an optimization to avoid sending huge terms to the gui just to step by them and update variables again. Even better would be to only update if necessary.

ucontext routines are deprecated in Snow Leopard and defining _XOPEN_SOURCE is the suggested remedy.
2009-12-18Test for reliable fpes on Darwin platforms without DARWIN_MODERN_MCONTEXTTrannie Carter
The mcontext_t structure changed between Tiger & Leopard and the erts configure script doesn't take this into account when testing for reliable floating point exceptions. HiPE is not enabled when reliable fpes are not detected. The PPC test preserves the pre-modern mcontext_t and so builds on Tiger, but I suspect that PPC/Leopard is broken. I don't have the header files to check modern PPC mcontext_t so I haven't changed that part of the test.
