2011-11-17Add restart_new_emulator instruction to kernel, stdlib and sasl appupsSiri Hansen
The appup files for kernel, stdlib and sasl did not contain any UpFromVsn and DownToVsn. This means that it was not possible to create a relup file with systool:make_relup if any of these applications had changed. This commit adds entries in the appup files for a maximum of two major releases back - all with only one upgrade instruction: restart_new_emulator. The point is to allow relups to be generated, but ensure that no soft upgrade is done for these three applications - i.e. they will always cause a restart of the emulator prior to all other upgrade instructions from other applications. Test cases (appup_test) are added to kernel_SUITE, stdlib_SUITE and sasl_SUITE. These all check that expected versions are matched in the appups, and illegal versions (older than two major releases, or in any other way illegal) do not match. The test is written in a general way where it is assumed that the version of these applications are stepped according the the rule that major releases step the second number, maintenance releases step the third number and patches step the fourth number.

2011-11-14Remove the undocumented function global:safe_whereis_name/1Hans Bolinder
2011-11-14Remove all use of global:safe_whereis_name/1Hans Bolinder
Calls to global:whereis_name/1 have been substituted for calls to global:safe_whereis_name/1 since the latter is not safe at all. The reason for not doing this earlier is that setting a global lock masked out a bug concerning the restart of supervised children. The bug has now been fixed by a modification of global:whereis_name/1. (Thanks to Ulf Wiger for code contribution.)
2011-11-14Fix a minor race in gen_fsmHans Bolinder
Fixed a minor race conditions in gen_fsm:start*: if one of these functions returned {error,Reason} or ignore, the name could still be registered (either locally or in global. This is the same modification as was done for gen_server in OTP-7669.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-10-17Make epp search directory of current file first when including another fileRichard Carlsson
The expected behaviour of a C-style preprocessor (such as Erlang's epp) is to allow a header file to include another header file in the same directory even though that directory is not explicitly in the include path, and even if the actual include path might reference another directory containing a file with the same name. For example, if src/foo.erl explicitly includes "../include/foo.hrl", then foo.hrl should be able to include "bar.hrl" in that same directory even though "../include" might not be in the search path, and even if another file named bar.hrl could be found using the search path it should not override the one in the same directory as foo.hrl. In Erlang, the most common situation is that a user of an installed application includes a main public header file using include_lib ("appname/include/foo.hrl") and that file includes a secondary header file "bar.hrl". However, if it does this using include_lib, it causes a bootstrapping problem - in the build environment for the application itself, the application is not necessarily found by name. On the other hand, if foo.hrl uses a plain include, then bar.hrl might be found when the application is built (if explicit paths are set in the makefils) but not later on when a user includes the main header file of the installed application via include_lib. By making -include always look in the directory of the current file before it uses the search path, this problem is remedied, and include directives behave in a more intuitive way. This completes a partial fix in R11 that only worked for include_lib().
2011-10-17Fix a bug in Dets concerning repair of almost full tablesHans Bolinder
A Dets table with sufficiently large buckets could not always be repaired. (Reported by Gordon Guthrie.) The format of Dets files has been modified. When downgrading tables created with the new system will be repaired. Otherwise the modification should not be noticeable.

2011-10-13Allow noncharacter code points in unicode encoding and decodingBjörn Gustavsson
The two noncharacter code points 16#FFFE and 16#FFFF were not allowed to be encoded or decoded using the unicode module or bit syntax. That causes an inconsistency, since the noncharacters 16#FDD0 to 16#FDEF could be encoded/decoded. There is two ways to fix that inconsistency. We have chosen to allow 16#FFFE and 16#FFFF to be encoded and decoded, because the noncharacters could be useful internally within an application and it will make encoding and decoding slightly faster. Reported-by: Alisdair Sullivan
2011-10-10Add a warning to docs about workers' shutdown strategyChristopher Faulet
2011-10-10Allow an infinite timeout to shutdown worker processesChristopher Faulet
Now, in child specification, the shutdown value can also be set to infinity for worker children. This restriction was removed because this is not always possible to predict the shutdown time for a worker. This is highly application-dependent.
2011-10-10Fix a minor bug in DetsHans Bolinder
If a Dets table had been properly closed but the space management data could not been read, it was not possible to repair the file.

2011-10-07Add '-callback' attributes in stdlib's behavioursStavros Aronis
Replace the behaviour_info(callbacks) export in stdlib's behaviours with -callback' attributes for all the callbacks.
2011-10-07Automatically generate 'behaviour_info' function from '-callback' attributesStavros Aronis
'behaviour_info(callbacks)' is a special function that is defined in a module which describes a behaviour and returns a list of its callbacks. This function is now automatically generated using the '-callback' specs. An error is returned by lint if user defines both '-callback' attributes and the behaviour_info/1 function. If no type info is needed for a callback use a generic spec for it.
2011-10-07Add '-callback' attribute to language syntaxStavros Aronis
Behaviours may define specs for their callbacks using the familiar spec syntax, replacing the '-spec' keyword with '-callback'. Simple lint checks are performed to ensure that no callbacks are defined twice and all types referred are declared. These attributes can be then used by tools to provide documentation to the behaviour or find discrepancies in the callback definitions in the callback module.

2011-09-27beam_lib: Handle rare race in the crypto key server functionalityBjörn Gustavsson
In rare circumstances, there can be a race when the crypto key server is started by beam_lib:crypto_key_fun/1 shortly after stopping it using beam_lib:clear_crypto_key_fun/0. The race occurs because the crypto key server first sends back the reply to the calling process, then terminates. (The race is probably more likely to happen on CPUs with hyper threading.)
