2015-06-18dialyzer: Expand opaque types before other typesHans Bolinder
Opaque types need to be expanded before record field types, otherwise any() could be used for opaque types.
2015-06-15dialyzer: Simplify some codeHans Bolinder
Remove what it seems redundant checks.
2015-06-15dialyzer: Fix a bug in the expansion of formsHans Bolinder
The check that a modified type of a field is a subtype of the declared type has been moved outside of the expansion of forms to avoid loops.

* legoscia/dialyzer/cache-hipe-binaries/OTP-12779: Dialyzer to cache results of HiPE compilation Change hipe_bifs:system_crc/1 to hipe_bifs:system_crc/0
2015-05-28Dialyzer to cache results of HiPE compilationMagnus Henoch
Cache the results of native compilation in $XDG_CACHE_HOME/dialyzer_hipe_cache. This can reduce the startup time significantly. If XDG_CACHE_HOME is unset, it defaults to $HOME/.cache. See the XDG Base Directory spec for more details: http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html Under that directory, create a subdirectory called ARCH-VERSION-CHECKSUM, where ARCH is the HiPE architecture, VERSION is the HiPE version number, and CHECKSUM is the return value of hipe_bifs:system_crc/0. Caching can be disabled by specifying --no_native_cache on the command line.
2015-05-25Update runtime_dependencies in application resource filesHans Bolinder
Applications that use the new erl_anno module are depending on STDLIB 2.5. Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the erl_anno module via the Yecc parsers only (the header file in lib/parsetools/include/yeccpre.hrl calls the erl_anno module). HiPE does not call the erl_anno module, but uses an exported type. We have chosen to make HiPE dependent on the erl_anno module.
2015-05-20dialyzer: Document dialyzer:gui() option 'check_plt'Hans Bolinder
* Mention the option 'check_plt' among gui() options. * No longer check a PLT twice when the analysis type is 'plt_check'. * No longer raise a case_clause error when checking a PLT finds warnings. Thanks to James Fish.
2015-05-05Fix a bug related to constraints generated for erlang:'*'/2Stavros Aronis
For Rst = A1 * A2, typesig for erlang:'*'/2 was constraining the arguments A1 and A2 in the 'reverse' direction by requiring that A2 is a subtype of Rst div A1, unless A1 is a hard zero. This is not correct: if for example both Rst and A1 are non_negative, such a constraint will first force A1 to be non-zero for the division to go through and then require A2 to be non_negative as non_negative div positive = non_negative, always (see commited test). In the fixed version, we are not constraining an argument if the other operand *may* be zero.

A minor re-factoring and generalization.
2014-10-08dialyzer: Ignore ERL_COMPILER_OPTIONS when compilingHans Bolinder
If, for instance, 'warn_unused_import' is present in ERL_COMPILER_OPTIONS then many files in Erlang/OTP (Kernel, STDLIB, ...) cannot be analyzed by Dialyzer since the option is not present when compiling Erlang/OTP, but 'warnings_as_errors' is. The case that ERL_COMPILER_OPTIONS contains 'warnings_as_errors' can only be handled by ignoring ERL_COMPILER_OPTIONS.
2014-10-08dialyzer: fix bug concerning compiler option 'warnings_as_errors'Hans Bolinder
A typical scenario: the type digraph() is used in R16 (compilation with the option 'warnings_as_errors' results in no warning); then the module is analyzed by a 17 Dialyzer where digraph() is obsolete, and since the warning is turned into an error Dialyzer fails to load the module. Thanks to Michael Truog.

2014-06-17[dialyzer] Fix handling of literal recordsHans Bolinder
This ticket is about records in Erlang code, and when to check the fields against the (optional) types given when defining records. Dialyzer operates on the Erlang Core format, where there are no trace of records. The fix implemented is a Real Hack: Given the new option 'dialyzer' erl_expand_records marks the line number of records in a way that is undone by v3_core, which in turn inserts annotations that can be recognized by Dialyzer.

The option `warn_export_vars` was erroneously written as `warn_exported_vars` in Makefiles of dialyzer and typer. As a result, `erlc` was silent about such warnings (why on earth doesn't it complain on unrecognized options??) which were corrected as part of this change.

On SMPs, the time reports that Dialyzer produced when crashing were inaccurate. Fix this by using wall_clock rather than runtime.
2014-03-28Dialyzer now plays nicely with funs that come as "external" argumentsStavros Aronis
Two steps are needed to make this work: 1) Avoid generating the additional "apply_constraint" in dialyzer_typesig by reporting every function argument as a potential external function (patch on dialyzer_dep). This will produce correct success typings for all functions in the test case, but dataflow would miss the key warnings that help identify the bugs. 2) Patch dialyzer_dataflow so that it uses the "handle just external" path as a fallback whenever there are any external calls. As a result, if we have info about some paths, then: a) use the old "handle known apply" code to mark these functions as used and b) ignore the generalized result and use the one found by typesig for the return value of the apply itself.
2014-03-24Correct some type declarationsKostis Sagonas
The types of some record fields were wrong. This file uses some module local format of race warnings and when the analysis is done transforms this format into the format of general dialyzer warnings. This change fixes the type declaration of the race_warning field of the #races{} record which was wrong. In addition, declared the type of the state field in some other record that, long ago, could not be declared since mutually recursive types were not supported by Dialyzer's analysis.
2014-03-24Use the ordsets:ordset(T) type instead of defining a local oneKostis Sagonas
2014-03-21dialyzer: generalize guard constraints in a new wayHans Bolinder
Guard constraints used to be limited to a certain depth, which handled mutually depending constraints safely, but also sometimes introduced unnecessary generalizations. This patch puts no explicit limit upon guard constraints (other than those that already exist in erl_types), but breaks cycles by replacing variables with the any() type. In some cases the old method resulted in more warnings, but since the limit was quite arbitrary and mutually depending guard constraints are (very) rare, the new method should been seen as an improvement since it handles cases that used to make Dialyzer loop or miss warnings.
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.
