2024-01-29Fix PLIST_API definitionsGravatar Nikias Bassen1-1/+1
2023-05-21Add explicit casts and fix return type mismatchesGravatar Nikias Bassen1-10/+12
2023-05-14bplist: Move realloc from parse_unicode_node() into plist_utf16be_to_utf8()Gravatar Nikias Bassen1-11/+12
It is very confusing to handle the reallocation (buffer shrinking) outside of the actual conversion function.
2023-05-13Move PLIST_API to the headersGravatar Nikias Bassen1-2/+2
2023-04-21bplist: Fix offset range checkGravatar Nikias Bassen1-1/+1

2023-02-07Add function to interface to allow enabling/disabling error/debug output for ↵Gravatar Nikias Bassen1-0/+5
the format parses This makes the `-d` option work in plistutil that wasn't doing anything
2023-02-06libcnary: Updated typedefs of node_t and node_list_t to contain pointerGravatar Nikias Bassen1-8/+8
This makes the code more readable. Obviously all the code that uses it is also updated.
2023-01-31bplist: Fix handling of PLIST_NULL node typeGravatar Nikias Bassen1-0/+1
2023-01-16Rename PLIST_UINT to PLIST_INT and add plist_new_int() and plist_get_int_val()Gravatar Nikias Bassen1-12/+12
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.
2022-09-05Get rid of casting a ptr to a 32 bit valueGravatar Dave MacLachlan1-2/+2
This causes a warning if `-Wbad-function-cast` is enabled on a build.
2022-08-24bplist: Fix strict aliasing violationsGravatar Matthew Smith1-3/+9
Casting a float pointer to an int pointer is a strict aliasing violation (-Wstrict-aliasing) and is undefined behaviour (although, it did not seem to cause any real issues). An optimising compiler should elide the memcopies added by this commit.
2021-12-22Add a return value to plist_to_* and plist_from_* functionsGravatar Nikias Bassen1-15/+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 Bassen1-0/+12
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().

2019-12-09bplist: use ptr_array instead of PLIST_ARRAY to store node indices for ↵Gravatar XD1-10/+10
recursing check This improves performance by at least 30% for large files, and also reduces the memory footprint.

2018-12-10Remove node_iterator and operate on node list directly to improve memory usageGravatar Nikias Bassen1-4/+1
2018-12-10bplist: Improve performance and memory usage when writing binary plistGravatar Nikias Bassen1-2/+84
2018-11-30bplist: Remove unnecessary allocations when parsing and writing unicode nodesGravatar Nikias Bassen1-88/+72

2017-05-31bplist: Prevent store to misaligned address when writing real/date nodesGravatar Nikias Bassen1-9/+9
ASAN reported possible undefined behaviour when writing float/double values to misaligned addresses.
2017-05-29bplist: Work around misaligned reads reported by AddressSanitizerGravatar Nikias Bassen1-3/+3
These misaligned reads reported by ASAN might lead to undefined behavior.

2017-04-19bplist: Fix integer overflow check (offset table size)Gravatar Nikias Bassen1-3/+17
2017-03-26bplist: Make sure sanity checks work on 32bit platformsGravatar Nikias Bassen1-10/+14
Because on 32-bit platforms 32-bit pointers and 64-bit sizes have been used for the sanity checks of the offset table and object references, the range checks would fail in certain interger-overflowish situations, causing heap buffer overflows or other unwanted behavior. Fixed by wideing the operands in question to 64-bit.
2017-02-10bplist: Fix data range check for string/data/dict/array nodesGravatar Nikias Bassen1-6/+6
Passing a size of 0xFFFFFFFFFFFFFFFF to parse_string_node() might result in a memcpy with a size of -1, leading to undefined behavior. This commit makes sure that the actual node data (which depends on the size) is in the range start_of_object..start_of_object+size. Credit to OSS-Fuzz

2017-02-05bplist: Add error/debug logging (only if configured with --enable-debug)Gravatar Nikias Bassen1-31/+112
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".
