strtok_r is not available on win32 and the designated strtok_s
function is reported to not work on windows xp. Hence we use an
easier an non-destructive implementation with strspn and strcspn
to strip out the whitespace.
|
|
this is a temporary fix, we'll replace strtok_r with a custom implementation soon.

Thanks to free2000fly for pointing this out. The issue was that
XML plists with comments converted to binary plists would result
in invalid binary nodes, thus converting back these binary plists
resulted in a crash.

This allows dylib to correctly find the library and fixes linking on OSX.

While iterating over all the keys stored in the source Dictionary
to copy them to create the copied Dictonary, the name of the key
being copied was only set to a non-NULL value for the first key
we copy. This was then leading to an assertion when trying to
create a std::string from a NULL pointer. Simple test-case:
int main()
{
PList::Dictionary a;
PList::String b("Hello");
PList::String c("Hi!");
PList::Dictionary d;
a.Insert("Key", &b);
a.Insert("Another Key", &c);
std::cout << a.ToXml() << std::endl;
d.Insert("dictionary", &a); //CRAAAAAAAAASH!
std::cout << d.ToXml() << std::endl;
return 0;
}
/* Output:
<?xml version="1.0" encoding="UTF-8"?>

Apple's activation server refuses XML tickets when this patch isn't applied.

- endianness issues: on big endian machines, writing out only part
of an integer was broken (get_needed_bytes(x) < sizeof(x))
-> shift integer before memcpy() on big endian machines
- alignment issues: unaligned reads when loading binary plist. Leads
to slow runtime performance (kernel trapping and fixing things up),
SIGBUS (kernel not helping us out)
-> introduce get_unaligned() and have the compiler generate the code
needed for the unaligned access
(note that there remains unaligned accesses that I haven't been able
to track down - I've seen 2 of them with test #2)
- type-punning issues: breaking strict aliasing rules can lead to
unexpected results as the compiler takes full advantage of the aliasing
while optimizing
-> introduce the plist_uint_ptr union instead of casting pointers
Tested on amd64, alpha and hppa.

In locales like German, a ',' is used as a decimal separator. When the
program calling plist_to_xml uses LC_NUMBER with something different
than a '.', parsing of the resulting XML document fails. This patch
fixes it.
|
|
This makes it possible to process the resulting char* directly as
a c-string without further copying.

* on armel system floating poing data can have different endianess than
rest of types; hence we fix arm endianess for defined(__VFP_FP__) to
be big/native; this also applies for data parsing/writing
* date parsing didnt flip the endianess back for little endian systems
when reading the values causing test failures; we fix this by ensuring
float endianess is applied when parsing

For string nodes, a set of special characters must be converted to
predefined xml entities. This patch adds an entitiy test case for
this and makes libplist pass it fine by explicitly adding text nodes.

Before recursing over its children, plist_free_node started by
detaching the current GNode from its parent which means that
calling g_node_destroy on the root of the tree was freeing only
the top-level GNode while what was intended was to free the whole
tree. Don't leak memory by not detaching children GNodes from their
parents so that g_node_destroy on the toplevel GNode can clean
everything.

The 2nd missing break was harmless since it fell through the default: case
which has a break, but it makes things more robust if we were ever to add
new cases to this switch. The 1st missing break; was causing warnings in
valgrind since we ended up calling strdup on a memory zone not containing
a \0 character.
