2010-11-22erl_types: Fix pretty rare crashes and an infinite loopKostis Sagonas
- Fixed pretty rare crash when taking the infimum of two tuple_sets (initial fix by Kostis Sagonas but then a better fix was provided by Stavros Aronis and this is the one adopted). - Fixed pretty rare crash when using parameterized types containing unbound variables (thanks to Nicolas Trangez for reporting it). - Fixed pretty rare infinite loop when refining the types of an SCC whose functions all returned none() (thanks to Stavros Aronis).
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
