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.
2012-01-25Ensure that generated record operations don't call local functionsBjörn Gustavsson
Consistently use external (remote) calls to the BIFs element/2, setelement/3, and is_record/3.

* 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.

* siri/stdlib/dialyzer-log_mf_h/OTP-9754: Fix dialyzer warning about gen_event callback init/1 in log_mf_h
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
2011-11-24filename: Eliminate failing call to Mod:module_info(source_file)Björn Gustavsson
Mod:module_info(source_file) is no longer supported (and have not been for a long time), so calling it will always fail.

The 'trace' and 'fast' options are no longer supported. While at it, correct the comment about option filtering.

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.

2011-11-17Add 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.

2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.
