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.

When "collapsing" heads of list elements from a list's tail into the list's head the new head can be different.

2012-04-18Revert "Extend erlang:port_info/1,2 to show the OS pid of a spawned process"Patrik Nyblom
This reverts commit d4667d383964c1550e0a91d64b674e84f6d07e3b. This commit was included by mistake, the correct patch will be merged from maint.

2012-04-17Extend erlang:port_info/1,2 to show the OS pid of a spawned processMatthias Lang
When spawning OS (unix) processes with erlang:open_port, store the resulting unix pid so that it can be queried later on using erlang:port_info/1,2.

2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
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.

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'.

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'().
