2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.

2012-02-07Reintroduce sensitive BIFs in erl_bif_typesPatrik Nyblom
This involves exception BIF's, guar BIF's and some other complicated BIF's Also some minor corrections to documentation and specs in erlang.erl Added comment for each spec in erlang.erl shadowed by erl_bif_types. Dialyzer test should now run well except for one or two cases.
2012-02-07Correct dializer errors in erlang.erl and othersPatrik Nyblom
New errors found when adding specs to erlang.erl and removing them from erl_bif_types are examined and corrected. Some errors was due to faulty specs, while others were actual errors in the code using BIF's.

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'.

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).

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.
