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.

2011-09-26erl_prim_loader: Eliminate dialyzer warningBjörn Gustavsson
The concat/1 function is now only used to append lists when constructing filenames. Thus it is too general and the first clause (that handles characters) will never be used. We could just remove the clause that is never used, but then the name 'concat' would be misleading and someone could use misuse it. Therefore, replace concat/1 with the join/2 function that can only be used for joining filename components.

concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

2011-06-08Teach prim_file:list_dir/1,2 to use fname chunksBjörn-Egil Dahlberg
The efile driver will now use chunked data on list_dir. This will lessen the number of sends to prim_file and hence improve performance. This method is utilized in both direct and async cases.

2011-06-08Replace atom in DRV macro in prim_file with stringStavros Aronis
An experimental version of Dialyzer discovered that the atom that replaced the DRV macro in prim_file ends up in calls to erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The documentation states that this call requires a string there. This change is also consistent with the one introduced in commit 0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

2010-10-20Fix hang in on_load handlers in embedded modeBjörn Gustavsson
In embedded mode, all on_load handlers will be called after loading all modules but before starting any servers. Therefore, if an on_load handler calls any function in the code module that calls the code server (such as code:priv_dir/1), there will be a deadlock because the code server has not yet been started. Fix this problem by invoking the on_load handlers after having started most servers in the kernel application.

2010-06-04Support opening files in exclusive modeMichael Santos
Add an option that atomically tests for the existence of a file and creates it if the file does not exist, by passing the O_EXCL flag to open() on Unix and CREATE_NEW flag on Windows. Support for O_EXCL varies across platforms and filesystems. {ok, Fd} = file:open("/tmp/foo", [write,exclusive]), {error, eexist} = file:open("/tmp/foo", [write,exclusive]).
