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.
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).
2018-12-17cython: Fix Node.to_bin() decodeGravatar Shane Garrett1-1/+1
Don't convert the string to UTF-8, just bytes. Fixes #109.

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.

2017-06-08configure: Allow building with sanitizers (without fuzzers)Gravatar Nikias Bassen1-10/+35
Passing --with-sanitizers will enable building with available sanitizers. Passing --with-fuzzers will enable building fuzzers which will also imply --with-sanitizers.

ASAN reported possible undefined behaviour when writing float/double values to misaligned addresses.

2017-04-20build: Fix check for previously installed cython bindingsGravatar Nikias Bassen1-0/+1
Due to the removal of pkg-config check for libxml2, $PKG_CONFIG was not defined and a check for libplist's include dir via pkg-config failed. By invoking PKG_PROG_PKG_CONFIG $PKG_CONFIG will be defined and the check works again.
2017-04-20build: Make sure plist.pxd is included in tarballsGravatar Christophe Fergeau1-3/+2
When generating a tarball on a system without cython installed, plist.pxd was missing, causing build failures later on when trying to use cython. This seems to be caused by EXTRA_DIST being inside a if HAVE_CYTHON block rather than being outside of it.

2017-04-14Initialize safe_year in time64.cGravatar Greg Dennis1-2/+2
Clang fails with stricter compilation options, because it thinks safe_year may be uninitialized at the return statement. The logic prevents it from being uninitialized, but probably worth the initialization to avoid the compiler error. The rest of libimobiledevice compiles successfully under the same options.
2017-04-06Update time64_limits.hGravatar Greg Dennis1-0/+2
This depends on the 'tm' type being declared, which is defined in time.h.

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.
