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.

Also fixes #126 by skipping the strlen() in the assert() if for some reason NULL is returned as data
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.

2016-06-29xplist: 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.

2009-11-19don't leak GNodes in plist_freeGravatar Christophe Fergeau1-1/+1
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.
2009-11-19add missing break; in switch statementGravatar Christophe Fergeau1-0/+2
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.
