2022-02-07xplist: Prevent undefined behavior by not trying to negate INT64_MINGravatar Nikias Bassen1-1/+1
2021-12-23xplist: Add special handling for PLIST_UID parsing from XMLGravatar Nikias Bassen1-5/+14
In XML, PLIST_UID nodes are stored as a dict with a "CF$UID" key and an integer value, so we want to make it a real PLIST_UID node internally.
2021-12-22Add a return value to plist_to_* and plist_from_* functionsGravatar Nikias Bassen1-16/+45
This way it can be easier determined why an import/export operation failed instead of just having a NULL result.
2021-12-19Add support for PLIST_NULL typeGravatar Nikias Bassen1-5/+19
2021-12-19Add new plist_mem_free() functionGravatar Nikias Bassen1-5/+0
Thanks to @azerg for bringing this to my attention. Instead of having multiple (internally identical) plist_*_free() functions, this commit introduces a single plist_mem_free() that can be used to free the memory allocated by plist_to_xml(), plist_to_bin(), plist_get_key_val(), plist_get_string_val(), and plist_get_data_val(). Note: This commit REMOVES plist_to_bin_free() and plist_to_xml_free().

2018-12-17xplist: Write base64 directly to output buffer to improve memory usageGravatar Nikias Bassen1-5/+2
Now that we grow the output buffer enough before writing XML output we can just write the base64 encoded data directly to the ouput buffer instead of using a heap buffer that will then be copied to the output buffer. This makes writing XML output more memory efficient (and slightly faster).

2018-09-04xplist: Assert when number of child nodes of PLIST_DICT is not evenGravatar Nikias Bassen1-0/+3
This should only happen due to misuse of the library, e.g. when calling plist_free() on a node that is a value node in a PLIST_DICT without properly removing the dictionary entry (key/value pair) and then calling plist_to_xml() on that dictionary.

2017-02-15xplist: Improve writing of large PLIST_DATA nodes by growing buffer in advanceGravatar Nikias Bassen1-0/+1
Instead of letting the buffer grow by just the amount of bytes currently transformed to base64 - which is basically line by line - we now calculate the size of the output blob in advance and grow the buffer accordingly. This will reduce the amount of reallocs to just one, which is especially important for large data blobs. While this is a general improvement for all platforms, it is on platforms like Windows where realloc() can be REALLY slow; converting a 20mb blob to XML can easily take up to a minute (due to the several hundred thousand calls to realloc()). With this commit, it will be fast again.
