2014-09-28Implement non-recursive node copyingArseny Kapoulkine
This makes node copying 6% faster, prevents it from ever running out of stack space and makes the profiling results more actionable for profilers that can't merge information from recursive calls. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1027 99668b35-9821-0410-8761-19e4c4f06640
2014-09-27contrib: Fix foreach.hpp for Boost 1.56.0Arseny Kapoulkine

2014-09-25Internal refactoring: rename xml_buffered_writer::write overloadsArseny Kapoulkine
Renames write to write_string and write_buffer to make it easier to distinguish between them in profiling runs and commit messages... git-svn-id: https://pugixml.googlecode.com/svn/trunk@1025 99668b35-9821-0410-8761-19e4c4f06640
2014-09-25Optimize xml_buffered_writer::write(char_t...)Arseny Kapoulkine
Make it easier for the compiler to generate good code by loading bufsize into a local once and returning new offset from flush(). This results in 7% performance gain. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1024 99668b35-9821-0410-8761-19e4c4f06640
2014-09-24Optimize xml_buffered_writer::write(const char_t*)Arseny Kapoulkine
Instead of computing the length and doing memcpy we now copy the head of the string into the buffer (like strcpy) and then use memcpy for tail if necessary. This results in 10-15% speedup for writing typical documents with a mix of short and long strings. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1023 99668b35-9821-0410-8761-19e4c4f06640

2014-09-23XPath: Optimize //name queries when possibleArseny Kapoulkine
//name means /descendant-or-self::node()/child::name, but we frequently can replace it with /descendant::name. This means we do not have to build up a temporary node set with all descendants that can lead to 3x speedups. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1021 99668b35-9821-0410-8761-19e4c4f06640

2014-09-21Optimize text_output_indentArseny Kapoulkine
We now precompute indent length and have a fast path for lengths 0..4 that avoids calling memcpy in a tight loop. This makes node output 20-30% faster if indentation is enabled. git-svn-id: https://pugixml.googlecode.com/svn/trunk@1018 99668b35-9821-0410-8761-19e4c4f06640

Use a special macro that unrolls the loop body and uses static branch prediction to improve code generation.

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

2014-02-25Revert automatic support for header-only mode since it creates problems with ↵Arseny Kapoulkine
qmake. Qmake treats all files that are #include-d as header files, even if the #include is guarded by an #ifdef. It looks like the only solution that allows for transparent header-only support based on preprocessor define involves moving the actual source into a separate header file and including this file in pugixml.cpp. Let's not do it yet. git-svn-id: https://pugixml.googlecode.com/svn/trunk@990 99668b35-9821-0410-8761-19e4c4f06640

Temp folder is the root folder on Windows; writing to the folder may require administrator rights.

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
