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.

Address sanitizer can detect underflows so we don't really need the custom
allocator.
Additionally, custom allocator can return memory that is not pointer-aligned;
this causes undefined behavior sanitizer to complain.

Work around -Wself-move using ref-deref.
|
|
Apply the usual workaround for for scoping issues. Also fix integer conversion
warning for BorlandC.

The memory_large_allocations test sometimes classified hash allocations
as page allocations since hash table could reach 512 entries.

Also test ranged for and copying big xpath_variable_set objects (to make
sure we actually handle hash collisions properly)
|
|
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").
|
|
|
|
Switch to malloc and manually aligning the pointer to the page boundary.
mmap is much slower than malloc; this change makes tests ~4x faster.
|
|
Since the type of the set was updated before assignment, assigning in
out-of-memory condition could change the type to not match the content.
|
|
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.

End of an era.
Make can be used for regular development (Linux/OSX), documentation building
and release packaging.
CMake can be used for regular development (Windows); it's also used by some
Linux distributions.
Continuous integration is now performed by Travis CI and AppVeyor.

Also fix test in wchar_t mode.

Ensure that all the necessary cleanup is performed in case the allocation fails
with an exception - files are closed, buffers are reclaimed, etc.
Any test that triggers a simulated out-of-memory condition is ran once again
with a throwing allocation function. Unobserved std::bad_alloc count as test
failures and require CHECK_ALLOC_FAIL macro.
Fixes #17.

Also add tests that verify save_file for absence of FILE leaks.

Previously attributes that were copied with their node used string sharing,
but standalone attributes that were copied using xml_node::*_copy(xml_attribute)
were not.
|
|
If an out of memory error happens in load_file there's a danger of leaking
the FILE object. Since there is a limited supply of the objects we can easily
test that the leak does not happen.
|
|
|
|
|
|
Previously there was no guarantee that the tests that check for out of memory
handling behavior are actually correct - e.g. that they correctly simulate out
of memory conditions.
Now every simulated out of memory condition has to be "guarded" using
CHECK_ALLOC_FAIL. It makes sure that every piece of code that is supposed to
cause out-of-memory does so, and that no other code runs out of memory
unnoticed.

We currently don't allocate/modify any state so there are no issues with this.
|
|
When parsing XPath variables, we need to perform a heap allocation; if it
fails, an xpath_exception instead of bad_alloc used to be thrown.
Now we throw the exception of a correct type so that xpath_exception means
'parsing error'.
|
|
|
|
This provides more coverage for #17.

Base directory is now using target basename.

Disable/change some tests for some compilers; use binary float comparison
for early MSVC versions.

Rename PAGE_SIZE to page_size to avoid define conflict with Android SDK.
Minor fixes in several tests.

Previously we omitted extra whitespace for single PCDATA/CDATA children, but in
mixed content there was extra indentation before/after text nodes.
One of the problems with that is that the text that you saved is not exactly
the same as the parsing result using default flags (parse_trim_pcdata helps).
Another problem is that parse-format cycles do not have a fixed point for mixed
content - the result expands indefinitely. Some XML libraries, like Python
minidom, have the same issue, but this is definitely a problem.
Pretty-printing mixed content is hard. It seems that the only other sensible
choice is to switch mixed content nodes to raw formatting. In a way the code in
this change is a weaker version of that - it removes indentation around text
nodes but still keeps it around element siblings/children.
Thus we can switch to mixed-raw formatting at some point later, which will be
a superset of the current behavior.
To do this we have to either switch at the first text node (.NET XmlDocument
does that), or scan the children of each element for a possible text node and
switch before we output the first child.
The former behavior seems non-intuitive (and a bit broken); unfortunately, the
latter behavior can cost up to 20% of the output time for trees *without* mixed
content.
Fixes #13.
