* hb/stdlib/digraph_condensation/OTP-9953: Remove loops from the graph created by digraph_utils:condensation/1
2012-03-05Leave control back to gen_server during supervisor's restart loopSiri Hansen
When an attempt to restart a child failed, supervisor would earlier keep the execution flow and try to restart the child over and over again until it either succeeded or the restart frequency limit was reached. If none of these happened, supervisor would hang forever in this loop. This commit adds a timer of 0 ms where the control is left back to the gen_server which implements the supervisor. This way any incoming request to the supervisor will be handled - which could help breaking the infinite loop - e.g. shutdown request for the supervisor or for the problematic child. This introduces some incompatibilities in stdlib due to new return values from supervisor: * restart_child/2 can now return {error,restarting} * delete_child/2 can now return {error,restarting} * which_children/1 returns a list of {Id,Child,Type,Mods}, where Child, in addition to the old pid() or 'undefined', now also can be 'restarting'.
2012-03-01Remove loops from the graph created by digraph_utils:condensation/1Hans Bolinder
The function digraph_utils:condensation/1 used to create a digraph containing loops contradicting the documentation which states that the created digraph is free of cycles. Thanks to Kostis Sagonas for finding the bug.

2012-01-26erl_lint: Disallow call to is_record/3 if there is a local is_record/3Björn Gustavsson
Attempting to call is_record/3 (without an erlang: prefix) from a guard if there was a local function named is_record/3 would cause a compiler crash. For consistency with other guard tests, disallow the call. is_record/2 in a guard will still be allowed (and work correctly) even if there is a local is_record/2. It could be argued that is_record/2 should be handled in the same way as is_record/3, but changing that now could break working code.

* bjorn/compiler/bif-call-bug/OTP-9866: erl_lint: Consistently reject local calls from guards
2012-01-17erl_lint: Consistently reject local calls from guardsBjörn Gustavsson
If a guard test (such as is_list/1) has a local definition in a module (or is imported), erl_lint will reject a call to it from a guard if the call is not at the top-level: foo(L) when is_list(L) =:= true -> %% Will be rejected. ok. is_list(_) -> ok. But if the call is at the top-level, it will be accepted (and cause a crash in a later compiler pass): foo(L) when is_list(L) -> %% Will be accepted by erl_lint ok. is_list(_) -> ok. This inconsistency was an oversight introduced when it became possible to override BIFs with local definitions.

2011-11-30Fix dialyzer warning about gen_event callback init/1 in log_mf_hSiri Hansen
The warning is about log_mf_h having a different spec for gen_event callback init/1 than defined in gen_event.erl. log_mf_h allows return value {error,Reason}, while gen_even only specifies successful return values. This commit add {error,Reason} as a valid return value to the gen_event callback, since this is handled by the code.
2011-11-29Fix dialyzer warnings in supervisorSiri Hansen
Dialyzer complained over a mismatch between the callback spec of Mod:code_change in gen_server and the spec of supervisor:code_change (which is the implementation of a gen_server Mod:code_change). This commit changes the callback spec to allow {error,Reason} as return value. Also, release_handler is updated to handle this return value.

2011-11-24Teach filename:find_src/1,2 to handle slim or stripped BEAM filesBjörn Gustavsson
filename:find_src/1,2 will crash when asked to find the source corresponding to a BEAM with no compilation options. A BEAM file can be missing compilation options if it has been stripped using beam_lib:strip/1 or compiled using the undocumented 'slim' option. Why this matters: If ERL_COMPILE_OPTIONS is set to +slim before building Erlang/OTP, there will be a crash in 'igor' during the building of the public_key application. ('igor' merges several source code files, and uses filename:find_src/1,2 to find the source code.) Change filename:find_src/1,2 to return an empty option list if there are no options in the BEAM file. Noticed-by: Per Hedeland

2011-11-24otp_internal: Stop warning for functions removed in R12 or earlierBjörn Gustavsson
When a deprecated function has been removed, the compiler will issue a warning if it sees a call to it, even for functions that were removed as far back as the R9 release. Since the otp_internal module grows when new deprecated functions are added, let's reduce its size somewhat by removing information about functions that were removed in the R12 release or earlier.
2011-11-24Add plugin support for alternative name lookupUlf Wiger
OTP behaviour instances (gen_server, gen_fsm, gen_event) can currently register themselves either locally or globally, and the behaviour libraries (including gen.erl) support both addressing methods, as well as the normal Pid and {Name, Node}. However, there are alternative registry implementations - e.g. gproc - and one can well imagine other ways of locating a behaviour instance, e.g. on a node connected only via a TCP tunnel, rather than via Distributed Erlang. In all these cases, one needs to write extra code to identify the behaviour instance, even though the instance itself need not be aware of how it is located. This patch introduces a new way of locating a behaviour instance: {via, Module, Name}. Module is expected to export a subset of the functions in global.erl, namely: register_name(Name, Pid) -> yes | no whereis_name(Name) -> pid() | undefined unregister_name(Name) -> ok send(Name, Msg) -> Pid Semantics are expected to be the same as for global.erl This can be used in all places where {global, Name} is accepted. faulty export in gen_fsm_SUITE.erl await process death in dummy_via:reset() fix error in gen_[server|fsm]:enter_loop() fix documentation

2011-11-17Add restart_new_emulator instruction to kernel, stdlib and sasl appupsSiri Hansen
The appup files for kernel, stdlib and sasl did not contain any UpFromVsn and DownToVsn. This means that it was not possible to create a relup file with systool:make_relup if any of these applications had changed. This commit adds entries in the appup files for a maximum of two major releases back - all with only one upgrade instruction: restart_new_emulator. The point is to allow relups to be generated, but ensure that no soft upgrade is done for these three applications - i.e. they will always cause a restart of the emulator prior to all other upgrade instructions from other applications. Test cases (appup_test) are added to kernel_SUITE, stdlib_SUITE and sasl_SUITE. These all check that expected versions are matched in the appups, and illegal versions (older than two major releases, or in any other way illegal) do not match. The test is written in a general way where it is assumed that the version of these applications are stepped according the the rule that major releases step the second number, maintenance releases step the third number and patches step the fourth number.
2011-11-14Remove all use of global:safe_whereis_name/1Hans Bolinder
Calls to global:whereis_name/1 have been substituted for calls to global:safe_whereis_name/1 since the latter is not safe at all. The reason for not doing this earlier is that setting a global lock masked out a bug concerning the restart of supervised children. The bug has now been fixed by a modification of global:whereis_name/1. (Thanks to Ulf Wiger for code contribution.)
2011-11-14Fix a minor race in gen_fsmHans Bolinder
Fixed a minor race conditions in gen_fsm:start*: if one of these functions returned {error,Reason} or ignore, the name could still be registered (either locally or in global. This is the same modification as was done for gen_server in OTP-7669.
