Using a list rather than a dict() for unified variables saves quite some time. In particular Dialyzer is a heavy user of t_unify().

2011-09-21erl_bif_types: Fix types for lists:key{search,find,member}/3Björn Gustavsson
The types for lists:key{search,find,member}/3 was computed under the assumption that the key should be matched (=:=) to the keys in the list, while the actual implementation uses comparison (==). Thus erl_bif_types:types/4 would wrongly report that lists:keyfind(42, 1, [{42.0,a}]) would always return 'false'.

* dev: Cleanup ETS bif's in hipe:erl_bif_types.erl (for dialyzer) Conflicts: erts/emulator/beam/erl_db.c
2011-09-16Quote atoms if necessary in typesTomas Abrahamsson
Atoms in some occurrences were not correctly quoted when formatted to strings, for instance by the typer program. Example: -module(tb). -export(['UPPERCASE-FUNCTION-NAME'/0, f1/0, f2/0, f3/0]). -record('UPPERCASE-RECORD-NAME', {x}). -record(r2, {'UPPERCASE-FIELD-NAME'}). -type 'UPPERCASE-TYPE-NAME'() :: integer(). 'UPPERCASE-FUNCTION-NAME'() -> ok. f1() -> #'UPPERCASE-RECORD-NAME'{x=1}. f2() -> #r2{'UPPERCASE-FIELD-NAME'=1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'(). f3() -> 1. Given the program above, the output from typer --plt some.plt tb.erl resulted in the following specs being printed: -spec UPPERCASE-FUNCTION-NAME() -> 'ok'. -spec f1() -> #UPPERCASE-RECORD-NAME{x::1}. -spec f2() -> #r2{UPPERCASE-FIELD-NAME::1}. -spec f3() -> UPPERCASE-TYPE-NAME(). This commit changes the output to become the following: -spec 'UPPERCASE-FUNCTION-NAME'() -> 'ok'. -spec f1() -> #'UPPERCASE-RECORD-NAME'{x::1}. -spec f2() -> #r2{'UPPERCASE-FIELD-NAME'::1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'().

2011-08-29Enhance Dialyzer's inference on comparisonsStavros Aronis
This patch makes Dialyzer aware of Erlang's total ordering of terms, enabling discrepancy detection in cases where e.g. integer() < tuple() is treated as a comparison that might also return false (when it is certain to always return true).

2011-08-25Add erlang:check_old_code/1Björn Gustavsson
Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.

concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

2011-01-31Sanitize the specs of the code moduleKostis Sagonas
After the addition of unicode_binary() to the file:filename() type, dialyzer started complaining about erroneous or incomplete specs in some functions of the 'code' module. The culprit was hard-coded information in erl_bif_types for functions of this module, which were not updated. Since these functions have proper specs these days and code duplication (pun intended) is never a good idea, their type information was removed from erl_bif_types. While doing this, some erroneous comments were fixed in the code module and also made sure that the code now runs without dialyzer warnings even when the -Wunmatched_returns option is used. Some cleanups were applied to erl_bif_types too.

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.
