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.

2012-03-20Make sure disk_log does not write too much dataHans Bolinder
While disk_log eagerly collects logged data for better performance, collecting too much data may choke the system and cause huge binaries to be written. The problem was addressed in OTP-9764, but the situation was not improved in all cases. Thanks to Richard Carlsson.

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.
2012-02-04Fix port leaking after controlling_process(Port, self())Ricardo
Add case to handle the situation when someone call {gen_tcp,gen_udp}:controlling_process(Port, self()). Also improve spec and doc from gen_udp and gen_sctp for controlling_process/2. To reproduce the issue, open an UDP port: 4> {ok,Port} = gen_udp:open(9000, [binary]). {ok,#Port<0.587>} 5> gen_udp:controlling_process(Port, self()). ok Simulate error: 6> 1=2. ** exception error: no match of right hand side value 2 Here is the leak: 7> inet:i().

* bjorn/kernel/on_load-bug/OTP-9875: Fix on_load handling in modules loaded by code:load_binary/3
2012-01-24beam_load.c: Allow stubs for BIFsBjörn Gustavsson
We want to be able to write type specifications for BIFs in the same way as for any other function. Currently, the type for BIFs need to be described in erl_bif_types. To avoid extending the compiler and Dialyzer with special directives for providing specifications for BIFs, we have decided to let the loader accept a local definition for a function which exists as a BIF. As an example, here is how a stub for lists:reverse/2 can be defined: -export([reverse/2]). -spec reverse([term()], term()) -> [term()]. reverse(_, _) -> erlang:nif_error(undef). Essentially, the loader will discard the local definition of reverse/2. Other functions in the same module must *not* do local calls to a BIF stub. If a local call to a BIF is found, the loader will refuse to load the module. That is, the following call is not allowed: reverse(List) -> reverse(List, []). but the following is: reverse(List) -> ?MODULE:reverse(List, []). A few words about the implementation. It turns out to be too complicated to actually discard the BIF stubs. Although it would be possibly with some jiggery pokery in ops.tab, the code would be difficult to maintain and it could slow down loading of modules that don't define BIFs (which are almost all modules). Therefore, the stub functions are kept in the loaded code, but their names in the func_info instruction are invalidated so that module_info(functions) can filter them out.

* maint: Correct two contracts in gen_sctp.erl
2012-01-23Fix on_load handling in modules loaded by code:load_binary/3Björn Gustavsson
In "13.4 Running a function when a module is loaded" in the Reference Manual, it is said that: A process that calls any function in a module whose on_load function has not yet returned will be suspended until the on_load function has returned. That did not work if the module was loaded using code:load_binary/3. Instead, the callers would get an 'undef' exception.

binary should be binary().
2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.
