strcat does not allow overlapping ranges; we didn't have a test for this
but now we do.
As an added bonus, this also means we only compute the length of each
fragment once now.
strconcat in the parsing loop only works if we know the source string
comes from the same buffer that we're parsing. This is somewhat
cumbersome to establish during parsing and it requires extra tracking
data, so we just disable this combination as it's unlikely to be
actually useful - usually append_buffer would be called on a possibly
empty collection of elements, not on something with PCDATA.
Add tests for double escape and a test for interaction with
parse_ws_pcdata flags; this behavior might change but we should pin the
current result.
Also slightly clean up the previously added test.
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.
Add tests for PI erroring exactly at the buffer boundary with
non-zero-terminated buffers (so we have to clear the last character
which changes the parsing flow slightly) and a test that makes sure
parse_embed_pcdata works properly with XML fragments where PCDATA can be
at the root level but can't be embedded into the document node.
The only point was to try to test all paths where we can run out of
memory while decoding something. It seems like it may be impossible to
actually do this given that we can't run all paths as wchar_t size
detection is done at runtime...
This makes sure all .reserve calls failure paths are covered. These
tests don't explicitly test if reserve is present on all paths - this is
much harder to test since not all modifications require reserve to be
called, so we'll have to rely on a combination of automated testing and
sanity checking for this.
Also add more parsing out of memory coverage tests.
Previously the error offset pointed to the first mismatching character, which
can be confusing especially if the start tag name is a prefix of the end tag
name. Instead, move the offset to the first character of the name - that way
it should be more obvious that the problem is that the entire name mismatches.
Fixes#112.
When using format_raw the space in the empty tag (<node />) is the only
character that does not have to be there; so format_raw almost results in
a minimal XML but not quite.
It's pretty unlikely that this is crucial for any users - the formatting
change should be benign, and it's better to improve format_raw than to add
yet another flag.
Fixes#87.
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.
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.
Introduce a notable behavior change in default parsing mode: documents without a
document element node are now considered invalid. This is technically a breaking change,
however the amount of documents it affects is very small, all parsed data still persists,
and lack of this check results in very confusing behavior in a number of cases.
In order to be able to parse documents without an element node, a fragment parsing flag is
introduced.
Parsing a buffer in fragment mode treats the buffer as a fragment of a valid XML.
As a consequence, top-level PCDATA is added to the tree; additionally, there are no
restrictions on the number of nodes -- so documents without a document element are considered
valid.
Due to the way parsing works internally, load_buffer_inplace occasionally can not preserve
the document contents if it's parsed in a fragment mode. While unfortunate, this problem is
fundamental; since the use case is relatively obscure, hopefully documenting this shortcoming
will be enough.

Parsing used to work on a non null-terminated buffer, inserting a fake null terminator to increase performance.
This makes it impossible to implement fragment parsing that preserves PCDATA contents (as witnessed by some
tests for boundary conditions that actually depended on this behavior).
Since almost all uses result in us allocating an internal buffer anyway, the new policy is to make sure all buffers
that are allocated by pugixml are null-terminated - the only exception now is external calls to load_buffer_inplace
that don't trigger encoding conversion.
