Align allocations to right end of page boundary to catch buffer overruns,
instead of unmapping on deallocations mark the page as no-access to guarantee
a page fault on use-after-free.
|
|
Instead just ignore the result of xargs.
|

|
|
This prevents malformed input XML with very deeply recursive DOCTYPE sections
from crashing the parser.
Fixes #29.
|
|
This removes the last code.google.com reference from documentation.
|
|
The current code is not optimal; since users actually read samples/tests
change them to use faster (and shorter!) code.
|
|
Also include math.h to fix issues on some compilers.
|
|
|
|
Also fix the float/double member order in the header file.
|
|
We test min/max and several different mantissas for the entire exponent range
for both float and double.
It's not clear whether all supported compilers provide an implementation of
sprintf/strtod that supports roundtripping so we may need to disable some of
these tests in the future.
|
|
These only do basic testing to make sure the paths are covered and trivial
values work.

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.

Make float/double round-trip

Unfortunately, standard headers on MinGW32 insist on undefining off64_t
and _wfopen extensions if __STRICT_ANSI__ is true (e.g. C++11 mode). This
leads to compilation errors since b7a1fec started to use _wfopen in strict
mode. That change erroneously checked GCC version - however, the version
itself is irrelevant; the actual criteria is whether mingw64 runtime is
used.
off64_t is not useful on MinGW32 since we only need it to open large files
on 64-bit platforms; unfortunately, the lack of _wfopen means we won't be
able to support wide-char paths on Windows for MinGW32.
Fixes #24.

Since MinGW 4.5 does not define these functions if __STRICT_ANSI__ is defined
(in case of _wfopen it defines it inconsistently between stdio.h and wchar.h)
use the baseline functions for MinGW 4.5 and earlier.
Fixes #23.

node_copy_string relied on the fact that target node had an empty name and
value. Normally this is a safe assumption (and a good one to make since it
makes copying faster), however it was not checked and there was one case when
it did not hold.
Since we're reusing the logic for inserting nodes, newly inserted declaration
nodes had the name set automatically to xml, which in our case violates the
assumption and is counter-productive since we'll override the name right after
setting it.
For now the best solution is to do the same insertion manually - that results
in some code duplication that we can refactor later (same logic is partially
shared by _move variants anyway so on a level duplicating is not that bad).
|
|
Add allow_insert_attribute (similar to allow_insert_child).
|
|
Remove redundant this-> from type() call (argument used to be called type,
but it's now type_).
Use _root member directly when possible instead of calling internal_object.
|
|
This will allow us to implement nodeset_eval_last evaluation mode if necessary
without relying on a fragile boolean argument.
|
|
Extract end of string to rend and add comments to translate_table.
|
|
Right now remove_node is only used in contexts where parent is reset after
removing but this might be important in the future.
|
|
Since depth is unsigned this is actually well-defined but it's better to not
have the underflow anyway.
|
|
|
|
This is more for consistency with the surrounding code than for performance.
|
|
Some compilers don't handle NaNs properly.
Some compilers don't implement fmod in a IEEE-compatible way.
Some compilers have exception handling codegen bugs (DMC...).
|
|
Also fix documentation jam rules for Windows.
|
|
|
|
Release date is (tentatively) 11/27.
|
|
|
|
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.
|
|
The behavior on OSX is different - we don't get a I/O error so the test is
useless.
|
|
|
|
Previously push_back implementation was too big to inline; now the common case
(no realloc) is small and realloc variant is explicitly marked as no-inline.
This is similar to xml_allocator::allocate_memory/allocate_memory_oob and
makes some XPath queries 5% faster.
|
|
In some cases constant overhead on step evaluation is important - i.e. for
queries that evaluate a simple step in a predicate expression. Eliminating
a redundant function call thus can prove worthwhile.
This change makes some queries (e.g. //*[not(*)]) 4% faster.

This reverts commit 98713bcba94b33b1b45a8891ac2e9e11305c7553.
Travis multi-OS feature is invite-only for now...
|
|
Hopefully OSX defaults to clang so we get as much coverage as before...
|
|
Previously setting a large page size (i.e. 1M) would cause dynamic string
allocation to assert spuriously. A page size of 64K guarantees that all
offsets fit into 16 bits.
|
|
Computed offsets for documents with nodes that were added using append_buffer
or newly appended nodes without name/value information were invalid.
|
|
This reduces the number of unsafe pointer manipulations.
|
|
These used to result in better codegen for unknown reasons, but this is no
longer the case.
|
|
Split number/boolean filtering logic into two functions. This creates an
extra copy of a remove_if-like algorithm, but moves the type check out of
the loop and results in better organized filtering code.
Consolidate test-based dispatch into apply_predicate (which is now a member
function).
