Define noexcept using _MSC_VER instead of _MSC_FULL_VER (first release
of MSVC 2015 should have it), remove redundant PUGIXML_HAS_NOEXCEPT and
define PUGIXML_NOEXCEPT_IF_NOT_COMPACT in terms of PUGIXML_NOEXCEPT.
* Adds a macro definition to be able to use noexcept with supporting compilers
* Adds noexcept specifier to move special members of xpath_node_set, xpath_variable_set and xpath_query, but not of xml_document as it has a throwing implementation
This change implements the initial version of move construction and
assignment support for documents.
When moving a document to another document, we always make sure move
target is in "clean" state (empty document), and proceed by relocating
all structures in the most efficient way possible.
Complications arise from the fact that the root (document) node is
embedded into xml_document object, so all pointers to it have to change;
this includes parent pointers of all first-level children as well as
allocator pointers in all memory pages and previous pointer in the first
on-heap memory page.
Additionally, compact mode makes everything even more complicated
because some of the pointers we need to update are stored in the hash
table (in fact, document first_child pointer is very likely to be there;
some parent pointers in first-level children will be using
compact_shared_parent but some won't be) which requires allocating a new
hash table which can fail.
Some details of this process are not fully fleshed out, especially for
compact mode; and this definitely requires many tests.
These functions were deprecated via comments in 1.5 but never got the
deprecated attribute; now is the time!
Using deprecated functions produces a warning; to silence it, this
change moves the relevant tests to a separate translation unit that has
deprecation disabled.
When this flag is true, PCDATA value is saved to the parent element instead of
allocating a new node.
This prevents some documents from round-tripping since it loses information,
but can provide a significant memory reduction and parsing speedup for some
documents.
Extra argument 'hint' is used to start the attribute lookup; if the attribute
is not found the lookup is restarted from the beginning of the attriubte list.
This allows to optimize attribute lookups if you need to get many attributes
from the node and can make assumptions about the likely ordering. The code is
correct regardless of the order, but it is faster than using vanilla lookups
if the order matches the calling order.
Fixes#30.
xpath_query, xpath_node_set and xpath_variable_set are now moveable.
This is a nice performance optimization for variable/node sets, and enables
storing xpath_query in containers without using pointers (it's only possible
now since the query is not copyable).
xpath_variable_set is essentially an associative container; it's about time it
became copyable.
Implementation is slightly tricky due to out of memory handling. Both copy ctor
and assignment operator have strong exception guarantee (even if exceptions are
disabled! which translates to "roll back on allocation errors").
Fix code style and revert redundant parameters/whitespace changes.
Also remove format_each_attribute_on_new_line - we're only introducing one
extra formatting flag. The flag implies format_indent but does not include its
bitmask.
Also add a few more tests.
Fixes#14.
Make float/double round-trip
This change also adds xml_text::set and xml_attribute::set_value overloads for float so that float is only printed using just enough digits to represent float, instead of enough digits to represent double.
It's sufficient to define PUGIXML_HEADER_ONLY anywhere now, source is included
automatically.
This is a second attempt; this time it includes a workaround for QMake bug
that caused it to generate incorrect Makefile.
This should completely eliminate the confusion between load and load_file.
Of course, for compatibility reasons we have to preserve the old variant -
it will be deprecated in a future version and subsequently removed.
select_node is shorter and mistyping nodes as node or vice versa should
not lead to any issues since return types are substantially different.
select_single_node method still works and will be deprecated with an
attribute and removed at some point.

This method is equivalent to xml_node::select_single_node. This makes
select_single_node faster in certain cases by avoiding an allocation and -
more importantly - paves the way for future step optimizations.

The page no longer contains 'data' field to use sizeof everywhere instead
of offsetof/sizeof inconsistency (that is required because some compilers
don't recognize offsetof as compile-time constant).
The page no longer contains 'memory' field that is now encoded as an
offset byte before the page - this allows us to save one pointer from the
static page in the document to keep the size the same as in v1.2 (binary
compatibility).

Moving nodes results in node order being different from order of allocated
names/values; since move is O(1) we can't mark the moved nodes in a
subtree so we have to disable the optimization for the entire document.
Similarly, if a node is composed of multiple buffers, comparing nodes in
different buffers does not result in meaningful order.
Since we value correctness over performance, mark the entire document in
these cases to disable sorting optimization.

This is required to make it possible to use a pointer to one of the
buffers with the document data in nodes but keep offset_debug and (more
importantly) XPath document order comparison optimization working.
The change increases memory page alignment to 64 bytes (so requires +32
bytes for every page allocation, which should not be a problem - even with
non-default 4k pages this is <1% extra cost, with default 32k pages the
overhead is 0.1%)

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.

Exposing true mutable iterators allows the user to violate sorting order
contract. However, some generic algorithms (i.e. Boost ForEach) require
iterator methods to be present.

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.
