2014-03-04match erlang keywords more carefullySteve Vinoski
Use word boundaries in some regex matching to avoid recognizing words that begin with keywords as keywords themselves, for example avoid recognizing a function named catcher as the catch keyword. Add a regression test for this problem.

2014-02-28Delay patching of closures to eliminate a race conditionBjörn Gustavsson
The loader of native code tries to avoid race condition by bringing down the system to a single scheduler. Unfortunately, that will not completely avoid race conditions beacuse other processes may still run while the code is being loaded. Therefore, we must still make sure that native code has been fully fixed up before it can be executed. Under unlucky circumstances, it was possible for the global name register process to call a fun in native code before the native code for the fun had been fully fixed up. The run-time system would crash when running the not-fully-fixed-up code. Here is a way to make the bug 100% reproducible. First add this function to the 'global' module: silly_looper(List) -> lists:foreach(fun(E) -> put(any_atom, E) end, List), silly_looper(List). Then insert the following code at the beginning of the init/1 function in the 'global' module: spawn_link(fun() -> silly_looper(lists:seq(1, 100)) end), The run-time system will crash during start up when the native code for the 'global' module is being loaded. What will happen is that lists:foreach/2 (which runs in native code) will call the native code for the fun in silly_looper/1 before the reference to 'any_atom' has been changed from a 0 to the proper tagged atom value. The put/2 BIF will exit when attempting to calculate the hash value for the illegal value 0 (it is not properly tagged). To eliminate this race condition, we must delay patching the native code addresses for a fun into the fun entry until the native code has been fully fixed up. We will use the new BIFs introduced in the previous commit. While we are at it, we will also make sure that we erase any temporary variables in the process dictionary used by the hipe_unified_loader module.
2014-02-28hipe: Break apart hipe_bif:make_fe/3 into two BIFsBjörn Gustavsson
This commit is a preparation for eliminating a race condition loading the native code for modules whose BEAM code has already been loaded. Here we introduce two new BIFs so that looking up a fun entry is separate from setting the native address in the fun entry.

* anders/diameter/grouped_decode/OTP-11675: Be lenient with the M-bit in Grouped AVPs
2014-02-24Be lenient with the M-bit in Grouped AVPsAnders Svensson
RFC 6733 says this, in 4.4: Receivers of a Grouped AVP that does not have the 'M' (mandatory) bit set and one or more of the encapsulated AVPs within the group has the 'M' (mandatory) bit set MAY simply be ignored if the Grouped AVP itself is unrecognized. The rule applies even if the encapsulated AVP with its 'M' (mandatory) bit set is further encapsulated within other sub-groups, i.e., other Grouped AVPs embedded within the Grouped AVP. The first sentence is mangled but take it to mean this: An unrecognized AVP of type Grouped that does not set the 'M' bit MAY be ignored even if one of its encapsulated AVPs sets the 'M' bit. This is a bit of a non-statement since if the AVP is unrecognized then its type is unknown. We therefore don't know that its data bytes contain encapsulated AVPs, so can't but ignore any of those that set the M-bit. Doing anything else when the type *is* known would be inconsistent. OTP-11087 (commit 066544fa) caused the M-bit on any unrecognized AVP to be regarded as an error, unrecognized being taken to mean "not explicitly defined as a member of its container". (That is, an AVP that can't be packed into a dedicated record field, which is slightly stronger than "not defined".) This fixed the original intention for top-level AVPs but broke the required leniency for Grouped AVPs whose type is known. This commit restores the leniency. Note that dictionary files need to be recompiled for the commit to have effect. Thanks to Rory McKeown for reporting the problem.

We don't want to introduce a potential incompatibility in a deprecated application, so we will fix the warning by removing the dead code that causes the warning.
