2023-02-06libcnary: Updated typedefs of node_t and node_list_t to contain pointerGravatar Nikias Bassen1-41/+41
This makes the code more readable. Obviously all the code that uses it is also updated.
2023-02-05Fix plist_sort() by swapping the nodes in the tree instead of their dataGravatar Nikias Bassen1-29/+33
The problem was that we swapped potential child node data between nodes, but their parents would not be updated that way, leading to double frees or segmentation faults when freeing a plist. This commit instead fixes this by swapping the actual nodes in the tree.

2023-01-16Rename PLIST_UINT to PLIST_INT and add plist_new_int() and plist_get_int_val()Gravatar Nikias Bassen1-8/+60
This properly supports getting and setting signed or unsigned integer values. Also, a new helper function plist_int_val_is_negative() was added to determine if a given #PLIST_INT node has a negative value or not. The old type PLIST_UINT is defined as a macro with the value of PLIST_INT for backwards compatibility. This commit also adds int vs. uint support to the C++ interface, and the python bindings in a hopefully useful way.

2021-12-22Add a return value to plist_to_* and plist_from_* functionsGravatar Nikias Bassen1-7/+11
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 Bassen1-0/+9
2021-12-19Add new plist_mem_free() functionGravatar Nikias Bassen1-0/+8
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().

2021-06-22[clang-tidy] Remove pointless constGravatar Rosen Penev1-1/+1

2020-05-25Return NULL from plist_copy() if passed a NULL pointerGravatar Xiao Deng1-1/+1
This will prevent an assert if a NULL pointer is passed, and can make writing some code easier and cleaner without the need for a NULL check. For example, plist_copy(plist_dict_get_item(dict, "abc")) would give us a copy of the dict's node if the dict has a value for the given key, or NULL without any further checks.

2019-08-09Make sure to copy hash table entries properly when cloning array/dict nodesGravatar Nikias Bassen1-18/+22
As mentioned in #142, plist_copy_node() was not correctly handling the hash tables when cloning array or dict nodes; it incorrectly filled the hash table with the original child node info, which effectively would lead to a segmentation fault / UaF if the original array/dict would be freed followed by an attempt to access an element in the new hash table.

2019-01-21plist: Add iterator for #PLIST_ARRAY nodesGravatar Nikias Bassen1-4/+34
Similar to #PLIST_DICT, an iterator can now be used for #PLIST_ARRAY nodes. Get an iterator with plist_array_new_iter() and use plist_array_next_item() to iterate over the elements.
2018-12-23plist: Improve plist_dict_next_item() drastically by iterating on node list ↵Gravatar Nikias Bassen1-10/+8
directly As Xiao Deng pointed out in #131, plist_dict_next_item() was very inefficient. For each iteration, node_nth_child() was called with the iterator value, which would walk through the child node list on EVERY iteration. If the dictionary is large this makes things very slow. More than that, after reaching the key node the code was calling node_nth_child() AGAIN (with iterator value + 1) to reach the value node, which would walk through the node list once more. This commit changes the iterator to be a node_t pointer so that the iteration is done on the node list directly.

2017-02-05bplist: Add error/debug logging (only if configured with --enable-debug)Gravatar Nikias Bassen1-0/+4
This commit adds proper debug/error messages being printed if the binary plist parser encounters anything abnormal. To enable debug logging, libplist must be configured with --enable-debug, and the environment variable PLIST_BIN_DEBUG must be set to "1".

2016-09-19Change internal storage of PLIST_DATE values from struct timeval to doubleGravatar Nikias Bassen1-22/+11
This removes the timeval union member from the plist_data_t structure. Since struct timeval is 2x64bit on 64bit platforms this member unnecessarily grew the union size to 16 bytes while a size of 8 bytes is sufficient. Also, on 32bit platforms struct timeval is only 2x32bit of size, limiting the range of possible time values. In addition the binary property list format also stores PLIST_DATE nodes as double.
2016-09-08Make sure plist_cleanup() symbol is actually publicGravatar Martin Szulecki1-1/+1
2016-06-29xplist: Plug memory leak when converting PLIST_UID nodes to XMLGravatar Nikias Bassen1-1/+1
In node_to_xml nodes of type PLIST_UID are temporarily converted to a PLIST_DICT for an appropriate XML output. Therefore a PLIST_KEY and a PLIST_UINT node is created and inserted into the PLIST_DICT node. Upon completion, the child nodes of the PLIST_DICT node are detached from the original node and freed, however the data of the child nodes - the key string and the uint value - are not. This commit fixes it.
2016-06-29plist_data_compare: Make sure to compare the node sizes for integer nodesGravatar Nikias Bassen1-0/+2
Without this check, e.g. the values -1 and 18446744073709551615 would yield in a match, since the comparison will just compare the uint64_t values. However, any value >= 9223372036854775808 and <= 18446744073709551615 is stored as a 128 bit value in binary plist format to make sure it is recognized as an unsigned value. We store it internally as a uint64_t value, but we set the size to 16 vs. 8 accordingly; so this commit will make sure the binary plist optimization will not re-use matching uint64_t values of actually mismatching signed/unsigned values.
2016-05-12Implement plist_from_memory()Gravatar Christophe Fergeau1-0/+15
Rather than having everyone reimplement binary/XML plist detection by looking at the first bytes of the plist content, it's better to do this detection in libplist and hide that internal detail from library users.
2016-05-12Add plist_is_binary()Gravatar Christophe Fergeau1-0/+9
It can be useful if one needs to know what type of plist a memory buffer contains.
