These tests are only testing attribute as_int in hopes that xml_text uses the
same underlying implementation (which it does).
|
|
They were still using Windows EOL by mistake
|
|
Previously test allocator only guaranteed alignment enough for a pointer.
On some platforms (e.g. SPARC) double has to be aligned to 8 bytes but pointers
can have a size of 4 bytes. This commit increases allocation header to fix that.
In practical terms the allocation header is now always 8 bytes.
|
|
This fixes tests in PUGIXML_NO_XPATH mode on SPARC64 (#48).
SPARC does not allow unaligned accesses - e.g. you can't read an unaligned int.
Normally pugixml does not perform unaligned integer/pointer accesses, but page
heap can allocate blocks that are not aligned so that we can detect a single-
byte read/write overrun.
Additionally, the hardcoded page size we're currently using is really system
specific - on SPARC the page size can be 8 Kb instead of 4 Kb so mprotect can
fail.

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.
