2010-12-16Fix type specification of the ets:new/2 BIFJesper Louis Andersen
The options for the ets:new/2 call has changed recently. There are read_concurrency hints as well as compressed tables. The hipe/dialyzer did not take this into account. This patch corrects the problem by going through the documentation and altering the type specification. The error fixed is with the dialyzer. When constructing an ETS table with, e.g., {read_concurrency, true}, the dialyzer will report that the caller of ets:new/2 will not return. ; First, we update the documentation from the ets man page. ; Second, we reorder the type specification of keypos so they appear in the same order as in the documentation. ; Finally, we add the missing read_concurrency and compressed Tweak options.
2010-12-13Fix native code compiler infinite loop and update type info for 're'Kostis Sagonas
The introduction of filenames being unicode binaries revealed a problem in the type analysis of the native code compiler which resulted in an infinite loop when compiling the 'filename' module. In addition, the hard-coded type information for the built-in functions of the 're' module was out-of-date, which resulted in erroneous type information for 'filelib' functions being stored in the PLT.

2010-11-29Fix type information of 'file' and 'code' modulesKostis Sagonas
Dialyzer for a long time now has had hard-coded type information about key functions of the 'file' and 'code' modules in 'erl_bif_types'. Some of this information was not up-to-date according to the published Erlang/OTP documentation, while some other part contained small errors. Now that specs are available, this information should be moved to the corresponding files, not be hard-coded in erl_bif_types. This change takes out all information for the 'file' module and fixes some small errors in type information for the 'code' module.
2010-11-22Merge branch 'ks/file_open-mode' into devBjörn Gustavsson
* ks/file_open-mode: Add the {encoding, _} options to file:open/2's modes
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).
2010-10-29Deeper unfolding of recursive typesKostis Sagonas
The change of taking out some hard-coded information about the file module uncovered that the unfolding of recursive types was probably too shallow. This has been fixed by unfolding it until a deeper limit (REC_TYPE_LIMIT). While at erl_types.erl also did some cleanup changes and fixed an erroneous io:format message.
2010-10-15Update httppacket type to return both strings and binariesLukas Larsson
2010-10-14Add the {encoding, _} options to file:open/2's modesKostis Sagonas
Although the {encoding, encoding()} set of options is documented in the manual page of the 'file' module, they do not appear in the Mode description on that page nor in the mode() type declaration. The patch adds this information in both the code of the module and the documentation of the module. To avoid duplication, the declaration of the encoding() type is added to the 'unicode' module where it most probably belongs. While at it, added a proper declaration for posix(), took out the now superfluous information about the types of file:open/2 from the erl_bif_types module, and corrected the return type of file:open/2 so that it corresponds to the published documentation.

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.

2010-06-09Merge branch 'ks/dialyzer-R14-fixes' into devErlang/OTP
* ks/dialyzer-R14-fixes: Various changes to dialyzer-related files for R14. OTP-8699 ks/dialyzer-R14-fixes Various changes to dialyzer-related files for R14. - Dialyzer properly supports the new attribute -export_type and checks that remote types only refer to exported types. A warning is produced if some files/applications refer to types defined in modules which are neither in the PLT nor in the analyzed applications. - Support for detecting data races involving whereis/1 and unregister/1. - More precise identification of the reason(s) why a record construction violates the types declared for its fields. - Fixed bug in the handling of the 'or' guard. - Better handling of the erlang:element/2 BIF. - Complete handling of Erlang BIFs.

2010-05-31Add erlang:nif_error/1,2Björn Gustavsson
A stub function that is supposed to be replaced by a NIF usually calls erlang:error/1 to cause an exception if the NIF library is not loaded. For example: foo() -> erlang:error(nif_not_loaded). The problem is that although erlang:error/1 will normally never be called, Dialyzer will think that any call to the function will fail and thus generate false warnings. Adding a spec for the function will not help because Dialyzer will not believe the spec. Add erlang:nif_error/1,2 that work exactly like erlang:error/1,2. Define the return types for both BIFs to be t_any(). erlang:nif_error is used like this: -spec foo() -> binary(). foo() -> erlang:nif_error(nif_not_loaded). (The -spec is optional but highly recommended, since Dialyzer otherwise has no chance to figure out the types.)
