2011-08-29Suppress some warnings about generation of non-returning funsStavros Aronis
No warnings are emitted for funs that are non-returning when the function that generates them has a contract that specifies that it will return such a non-returning fun. The actual bug, reported by Tuncer Ayaz and simplified by Maria Christakis is included in Dialyzer's tests.

2011-08-17Fix dialyzer warning on default clause for binary comprehensionIvan Dubrov
Fixed dialyzer warning occuring on binary comprehension of form "<< <<>> || {A, B} <- [{a, b}] >>" caused by default clause inserted by compiler. Since this clause is different from the case of list comprehension, dialyzer fails to suppress that warning.
2011-08-01Fix bug when reporting unused functionsStavros Aronis
2011-05-23Fix crash when a contract range warning is emitted for a module already in pltStavros Aronis
Warnings about wrong contract ranges are post-processed to be displayed in the file/line that contains the contract, although they can also be emitted while processing other modules. For this relocation to succeed the module that contains the contract should be currently under analysis. If this is not the case the warning is displayed in the file/line of the call that proves the discrepancy in the contract.
2011-05-13Fix server loop detectionStavros Aronis
Dialyzer does not normally emit warnings for functions that implement non-terminating server loops. This detection failed when some of the elements in an SCC terminated normally (being for example list comprehensions or other generic anonymous functions that were included in the SCC). This patch fixes that.

2011-03-31Fix crash related with the contract blame assignment patchStavros Aronis
The relevant commit is 8342fcf5395133a19d647f2ace606af9b7fc1732. The old patch could emit warnings even for function that had a problematic spec even without refinement. This warnings would consume the relevant invalid spec warnings. This patch takes care of this by ensuring that normal invalid spec messages are emitted if the call that triggers the blame contract range warning is in another module.

2011-01-20Add a --fullpath option to DialyzerKostis Sagonas
This change adds a --fullpath option to Dialyzer, which makes the warning messages contain the full path of the corresponding file. Original patch submitted by Magnus Henoch (legoscia) on 15/9/2010 and cooked to death in the 'pu' branch all this time. The patch was essentially correct and most of it has been used as is, but there have been some changes to make the code slightly prettier, avoid some code duplication, and add documentation to dialyzer's doc files and to its help message.
2011-01-18Fix warnings about guards containing notStavros Aronis
The wording of warnings about unsatisfiable guards that used 'not' was incorrect (the 'not' was not mentioned and it appeared as "Guard test is_atom(atom()) can never succeed").
2011-01-18Fix errors in the handling of 'and'/'or' guardsStavros Aronis
Apart from the obvious bug in the negative evaluation of an 'and' guard, Dialyzer handled dont_know cases rather single-mindedly towards the positive branch. This patch allows for negative results as well and does some clever guesses to narrow them down. It was constructed similarly to the handling of the 'not' guard.

2010-12-20Fix bug in the handling of 'or' by DialyzerStavros Aronis
Dialyzer had a minor issue when the arguments of the built-in function 'or' had the fixed value 'false'. This testcase should return no warnings: -module(false_false). -export([false_or/0]). false_or() -> false or false.

2010-11-30dialyzer: Add support for multiple PLTsMaria Christakis
This new feature is able to take multiple PLTs, merge them during the start of the analysis, and work from there. This works provided that the PLTs do not have a module with the same name appearing in more than one PLT. The PLTs are created in the usual way: dialyzer --build_plt --output_plt PLT_1 FILES_TO_INCLUDE ... dialyzer --build_plt --output_plt PLT_N FILES_TO_INCLUDE and then can be used in either of the following ways: dialyzer FILES_TO_ANALYZE --plts PLT_1 ... PLT_N or: dialyzer --plts PLT_1 ... PLT_N -- FILES_TO_ANALYZE (Note the -- delimiter in the second case)

2010-11-09dialyzer: Speed up analysis of nested list comprehensionsKostis Sagonas
Nested list comprehensions are translated into strongly connected funs but dialyzer ignored this. This meant that self-recursive analysis was normally executed for each fun and the whole fixpoint took some time to calculate. This patch adds every fun found in constraint generation to the SCC that is under analysis and then solves the SCC as a whole. Possible issues: - The returned dict contains more entries than usual. This triggered a bug in contract checking that is dealt with is this patch as well (dialyzer_contracts.erl). - As it's not easy to tell apart real fun SCCs from simple funs it performance might be hampered in the simple funs case. While doing these changes, also added and strengthened some specs. In addition, incorporated a modified patch by Ahmed Omar that fixes a bug in dialyzer_analysis_callgraph module that kept the files of only one selected directory in dialyzer's GUI.

2010-09-24Fix two errors in dialyzerKostis Sagonas
Changes which fix some problems reported by dialyzer users: 1. The handling of nested opaque types 2. The handling of remote types in record expressions used as types While at it, updated dialyzer's RELEASE_NOTES to reflect these fixes and did some cleanups to dialyzer_utils.erl so that it gets in sync with dialyzer's main development branch.

2010-06-07Fix confusing dialyzer warnings for is_record/2 with illegal recordsBjörn Gustavsson
In commit 1858cb81391d2bce29b4b7620574ca60128cebf7, erl_expand_records started to optimize is_record/2 in guards by replacing it with pattern matching (if possible). Unfortunately, dialyzer will no longer see the code before the optimization, so any warnings produced in code such as: case ExprNotProducingRecord#rec{} of X when is_record(X, rec, N) -> ... will refer to the optimized code and not the source code, which is confusing for the user. Introduce the no_is_record_optimization option for turning off the optimization and use it in dialyzer. Reported-by: Kostis Sagonas
