2011-11-17otp_build: Disable FPE by default on LinuxSverker Eriksson
FPE = floating point exceptions
2011-11-17stdlib: Make sure qlc_SUITE:otp_6964 restores backtrace_depthSverker Eriksson
2011-11-17erts: Add test for inf/NaN intermediate float resultsSverker Eriksson
Make sure that badarith is thrown even if end result is not inf/NaN
2011-11-17hipe,erts: Allow hipe without floating point exceptionsSverker Eriksson
2011-11-17hipe: Fix bug in hipe_rtl_lcm:calc_killed_expr_bbSverker Eriksson
Bug causing hipe to crash. Only provoked when changing the RTL generation for floating point operations. hipe_rtl:defines() was called with a expression ID instead of an expression. Use expr_id_map_get_expr() to get expression from ID. Need to pass along IdMap in order to do that.
2011-11-17erts: Rename macros used by float instructions without FPESverker Eriksson
No semantic change, just code clarification. Use unique macro names instead of redefining the original ones.

2011-11-14erlc: Do not bind schedulers when invoking "erl"Björn Gustavsson
If parallel make is used, several instance of 'erlc' is likely to be invoked at once. Therefore, the default binding of schedulers to CPU cores will do no good. (With this change, the build of Erlang/OTP with six threads finished in about 7 minutes; without in about 11 minutes.)

2011-11-13Make sure only one thread exits the runtime systemRickard Green
The runtime system crashed if more than one thread tried to exit the runtime system at the same time.
2011-11-13Use critical sections as mutex implementation on WindowsRickard Green
Windows native critical sections are now used internally in the runtime system as mutex implementation. This since they perform better under extreme contention than our own implementation.
2011-11-13Use generic lock-free queue for async threadsRickard Green
Queues used for communication between async threads and scheduler threads have been replaced with lock-free queues. Drivers using the driver_async functionality are not automatically locked to the system anymore, and can be unloaded as any dynamically linked in driver. Scheduling of ready async jobs is now also interleaved in between other jobs. Previously all ready async jobs was performed at once.
2011-11-13Use generic lock-free queue for misc aux workRickard Green
2011-11-13Implement generic lock-free queueRickard Green
The implementation of an ERTS internal, generic, many to one, lock-free queue for communication between threads. The many to one scenario is very common in ERTS, so it can be used in a lot of places in the future. Changing to this queue from a lock based queue, however, often requires some redesigning. This since we have often used the lock of the queue to protect other information too.
2011-11-13Replace system block with thread progress blockRickard Green
The ERTS internal system block functionality has been replaced by new functionality for blocking the system. The old system block functionality had contention issues and complexity issues. The new functionality piggy-backs on thread progress tracking functionality needed by newly introduced lock-free synchronization in the runtime system. When the functionality for blocking the system isn't used there is more or less no overhead at all. This since the functionality for tracking thread progress is there and needed anyway.
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.

Fix path filters Support more top-level primary expressions Accumulate comments in element nodes Add `default_attrs` option Allow whole documents to be returned Track parents and namespace in `#xmlAttribute` nodes Track parents in `#xmlPI` nodes Set `vsn` field in `#xmlDecl` record Fix namespace-conformance constraints
2011-11-11Fix bugs and add a flag to skip commentsLars Thorsen
Add flag {comments, Flag} to xmerl_scan for filtering of comments. Default (true) is that xmlComment records are returned from the scanner and this flag should be set to false if one don't want comments in the output. Fix some bugs to get the test cases to run clean.
2011-11-11Implement namespace axisAnthony Ramine
Namespace nodes are represented as `#xmlNsNode` records. Now that the namespace axis is correctly implemented, attributes nodes corresponding to attributes that declare namespaces are ignored. See [5.3 Attribute Nodes][xpath-5.3]: > There are no attribute nodes corresponding to attributes > that declare namespaces. [xpath-5.3]: http://www.w3.org/TR/xpath/#attribute-nodes
2011-11-11Add `#xmlPI` support to xmerl_xpath:write_node/1Anthony Ramine

2011-11-11Fix path filtersAnthony Ramine
2011-11-11Support more top-level primary expressionsAnthony Ramine
This change allows numbers and literals to be used as top-level primary expressions without failing: 1> xmerl_xpath:string("3", Doc). #xmlObj{type = number,value = 3} 2> xmerl_xpath:string("'foo'", Doc). #xmlObj{type = string,value = "foo"} We still need to allow arithmetic, comparative, boolean and negative expressions, as in `xmerl_xpath_pred:expr/2`.
2011-11-11Accumulate comments in element nodesAnthony Ramine
2011-11-11Add `default_attrs` optionAnthony Ramine
When `default_attrs` is `true`, any attribute with a default value defined in the doctype but not in the attribute axis of the currently scanned element is added to it.
2011-11-11Allow whole documents to be returnedAnthony Ramine
Functions `xmerl_scan:file/2` and `xmerl_scan:string/2` now accepts a new option `{document, true}` to produce a whole document as a `xmlDocument` record instead of just the root element node. You may wonder why this would be useful, this option is the only way to get to the top-level comments and processing instructions without hooking through the customization functions. Those nodes are needed to implement [Canonical XML][c14n-xml] support. [c14n-xml]: http://www.w3.org/TR/2008/PR-xml-c14n11-20080129/ "Canonical XML"

2011-11-11Fix namespace-conformance constraintsAnthony Ramine

2011-11-10erts: Teach VM to reallocate beam catch tableBjörn-Egil Dahlberg
Previously this table were statically allocated to 16*1024 entries. Now the default size is 1024 entries but that is doubled each time the limit is reached. Theoretical upper limit is 2^26 entries (the remaining bits on a catch datatype) in a 32 bit system.
