Intel compiler by default sets flush-to-zero flags which causes our
denorm test to produce 0.0. So make sure that denorms work on FPU before
testing the string output.
Fixes#218.
On some Debian systems it looks like we *can* open the current folder as
a file and read its contents, but parsing the result produces an empty
document. We now handle this case as well.
Fixes#225.
Several tests got the buffer size wrong when sizeof(char_t)>1, and one
test didn't meet the carefully tuned allocation criteria under compact
mode due to the hash table usage and had to be changed a bit.
Apparently at some point OSX behavior when reading /dev/tty switched
from "can't open the file" to "the file can be opened and 0 bytes can be
read from it" which generates a wrong error and doesn't exercise the
code path we care about.
This change implements move ctor and assign support for xml_document.
All node handles remain valid after the move and point to the new document; the only exception is the document node itself (that remains unmoved).
Move is O(document size) in theory because it needs to relocate immediate document children (there is just one in conformant documents) and all memory pages; in practice the memory pages only need the header adjusted, which is ~0.1% of the actual data size.
Move requires no allocations in general, except when using compact mode where some moves need to grow the hash table which can fail (throw).
Fixes#104
We now check that appending a child to a moved document performs no
allocations - this is already the case, but if we neglected to copy the
allocator state this test would fail.
These just verify that move ctor/assignment operator work as expected in
simple cases - there are a number of ways in which the internal
structure can be incorrect...
These tests simulate various error conditions when reading data from
streams - seeks failing in seekable streams, underflow throwing an
exception causing read to set badbit, etc.
This change also adjusts memory thresholds to cause a reliable out of
memory during construction of a final buffer for non-seekable streams.
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.
Add memory allocation failure test for concact with a very large list
and make sure we have every single axis covered with and without a
predicate, with and without a previous step.
New tests try to load a folder as an XML document, and a device. Both
are intended to exercise some otherwise non-hittable error paths in
load_file implementation.
This adds tests that complete branch coverage in compact pointer
encoding/decoding code (previously first_attribute was always encoded
using compact encoding in the entire test suite).
