2013-12-12Support non top level letrecs in dialyzerJosé Valim
Dialyzer so far only supported letrecs at the top-level and comprehension-like letrecs (i.e. that were directly applied) in their body. This commit address this issue by storing in the callgraph bound letrec labels pointing to their functions. This information is then used by the dataflow to properly lookup recursive definitions.
2013-11-13Remove the --wx option and promore the --gui to use the wx-based GUIKostis Sagonas
2013-11-13Remove the GS-based GUI of DialyzerKostis Sagonas
R17 will come without support for 'gs' so the old gs-based GUI of dialyzer has been removed.

2013-04-24[dialyzer] Fix a bug concerning the --gui and --wx optionsHans Bolinder
A bug that made it impossible to do any analyses from the GUI has been fixed. The bug was introduced in dialyzer-2.5.2.

* sa/dialyzer-bitstring-fixes/OTP-11027: Minor refactorings Fix minor error in natively compiled module list Fix notification for duplicate modules Fix an error in the type inference of bitstring data

2013-04-08Fix minor error in natively compiled module listStavros Aronis
Even though dialyzer_typesig is the module doing most of the work, compiling it to native code twice will not make it faster than the rest. :-)
2013-04-08Fix notification for duplicate modulesStavros Aronis
Dialyzer fails when asked to analyze multiple modules with the same name, but the error message was erroneous. With this patch Dialyzer generates a correct error message. Bug reported and patch submitted by Maxim Treskin.
2013-04-08Fix an error in the type inference of bitstring dataStavros Aronis
Dialyzer was constraining bitstring data used in the construction of other bitstring values too much. These constraints have now been relaxed.
2013-03-26Improve Dialyzer output for scan errorsMagnus Henoch
To reproduce, create an empty file "foo.erl" and run dialyzer on it. Results without this patch: $ dialyzer --src /tmp/foo.erl Checking whether the PLT /Users/magnus/.dialyzer_r16_plt is up-to-date... yes Proceeding with analysis... dialyzer: Analysis failed with error: Could not scan the following file(s): [{"/tmp/foo.erl", ["/tmp/foo.erl:1: no module definition\n"]}] Last messages in the log cache: Reading files and computing callgraph... Results with this patch: $ dialyzer --src /tmp/foo.erl Checking whether the PLT /Users/magnus/.dialyzer_r16_plt is up-to-date... yes Proceeding with analysis... dialyzer: Analysis failed with error: Could not scan the following file(s): /tmp/foo.erl:1: no module definition Last messages in the log cache: Reading files and computing callgraph...
2013-03-06Include module, function and arity in Dialyzer's "overlapping domain" warningsMagnus Henoch
The function name can give information that the line number doesn't, for example when using a parse transform that creates new functions.

* sa/dialyzer-list-spec/OTP-10740: Report spec discrepancy on mismatching lists
2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.
2012-12-20Report spec discrepancy on mismatching listsStavros Aronis
This patch enables Dialyzer to detect cases where a function has a specification for a return type containing some list with elements different than the ones Dialyzer's own algorithm can infer e.g. a function specified to return [atom()] when actually [[atom()]] is returned. Previously Dialyzer remained silent, under normal operation, seeing that these two types have the empty list as a common element, so they were not 'completely irrelevant'.

This extension allowed minimal detection of race conditions that were passing through behaviour API calls, but had no tests in any suite and also caused a crash in R15B02.

2012-09-24dialyzer: Do not output warnings for unused funsHans Bolinder
Dialyzer no longer outputs warnings for unused anonymous functions ("funs"). Warnings are still output for unused functions. Funs in functions with -nowarn_unused_function attributes generated warnings for unused functions. Unused list comprehensions also generated warnings for unused funs.

2012-08-24Stop a forgotten server processKostis Sagonas
Dialyzer forgot to stop a server process before finishing its analysis. This is a concurrency error detected by Concuerror.

2012-08-21Fix a bug in dialyzer_dataflowHans Bolinder
2012-08-21Add an undocumented option [--solver [v1 | v2]]Hans Bolinder
The original implementation of the type signature solver is called 'v1' and the newly introduced alternative implementation is called 'v2'. It is possible to run just the one of the solvers (in case there is a bug in for instance the v2 implementation) or both solvers ("--solver v1 --solver v2"). In the latter case an error is thrown if the outcome differ.
2012-08-21Add an alternative implmentation of the typesignature solverHans Bolinder
An alternative implementation of the solver in dialyzer_typesig has been introduced. It is faster than the original implementation. Note: there is code for "loop detection". Where a loop occurs, the evaluation is stopped and the current solution returned. This behaviour is consistent with how the original implementation works. There are a few known cases where the loop detection kicks in. They are due to bugs which will hopefully be fixed in a near future.

2012-06-01Bug fixes and improvements of dialyzer_typesigHans Bolinder
1. Sometimes the solver forgot that a list had entered the error state. The bug has been fixed by storing the atom 'error' in MapDict. An example where the bug occurred is io_lib_pretty:printable_bin(). The returned spec was weaker than it should have been, but the fix-point loop hid the bug (in this case). 2. lists:partition() has been substituted for lists:splitwith() in enumerate_constraints(). This fix together with 3. solves a problem with long execution times for deeply nested fun:s. An example which is now much faster is lib/compiler/test/lc_SUITE:deeply_nested/1 (included as dialyzer/test/small_SUITE_data/src/deep_lc.erl). 3. The calculation of components in enumerate_constraints() has been simplified and optimized. The important thing here is that _all_ of the simple constraints have been saturated before entering the complex part. 4. The pretty printing of constraints has been improved.
