2014-08-26Unroll performance-critical loops 4xArseny Kapoulkine
Use a special macro that unrolls the loop body and uses static branch prediction to improve code generation. This increases performance across all data sets from benchmark; clang x64 is 10%-40% faster, clang x86 is 5%-20% faster, msvc is 5%-10% faster. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1008 99668b35-9821-0410-8761-19e4c4f06640

The operations itself are O(1) since they just rearrange pointers. However, the validation step is O(logN) due to a sanity check to prevent recursive trees. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1002 99668b35-9821-0410-8761-19e4c4f06640

2014-06-01Improve XPath allocator performanceArseny Kapoulkine
When allocating new pages, make sure that the page has at least 1/4 of the base page size free. This makes sure that we can do small allocations after big allocations (i.e. huge node lists) without doing a heap alloc. This is important because XPath stack code always reclaims extra pages after evaluating sub-expressions, so allocating a small chunk of memory and then rolling the state back is a common case (filtering a node list using a predicate usually does this). A better solution involves smarter allocation rollback strategy, but the implemented solution is simple and practical. git-svn-id: https://pugixml.googlecode.com/svn/trunk@999 99668b35-9821-0410-8761-19e4c4f06640

2014-02-11Implement document fragment parsing.Arseny Kapoulkine
Introduce a notable behavior change in default parsing mode: documents without a document element node are now considered invalid. This is technically a breaking change, however the amount of documents it affects is very small, all parsed data still persists, and lack of this check results in very confusing behavior in a number of cases. In order to be able to parse documents without an element node, a fragment parsing flag is introduced. Parsing a buffer in fragment mode treats the buffer as a fragment of a valid XML. As a consequence, top-level PCDATA is added to the tree; additionally, there are no restrictions on the number of nodes -- so documents without a document element are considered valid. Due to the way parsing works internally, load_buffer_inplace occasionally can not preserve the document contents if it's parsed in a fragment mode. While unfortunate, this problem is fundamental; since the use case is relatively obscure, hopefully documenting this shortcoming will be enough. git-svn-id: https://pugixml.googlecode.com/svn/trunk@980 99668b35-9821-0410-8761-19e4c4f06640
2014-02-10Use a null-terminated buffer for parsing as often as possible.Arseny Kapoulkine
Parsing used to work on a non null-terminated buffer, inserting a fake null terminator to increase performance. This makes it impossible to implement fragment parsing that preserves PCDATA contents (as witnessed by some tests for boundary conditions that actually depended on this behavior). Since almost all uses result in us allocating an internal buffer anyway, the new policy is to make sure all buffers that are allocated by pugixml are null-terminated - the only exception now is external calls to load_buffer_inplace that don't trigger encoding conversion. git-svn-id: https://pugixml.googlecode.com/svn/trunk@977 99668b35-9821-0410-8761-19e4c4f06640
