2020-05-13Don't call memcpy with NULL as 1st parameter.John MacFarlane
This is illegal according to the C standard, sec. 7.1.4. "If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." 7.24.1(2): "Where an argument declared as size_t n specifies the length of the array for a function, n can have the value zero […] pointer arguments on such a call shall still have valid values, as described in 7.1.4." See https://www.imperialviolet.org/2016/06/26/nonnull.html

2020-02-16Fix #220 (hash collisions for references).John MacFarlane
This commit ports Vicent Marti's fix in cmark-gfm. (384cc9db4cd7a90f59c0751e58eb7b3023d38b85) His commit message follows: As explained on the previous commit, it is trivial to DoS the CMark parser by generating a document where all the link reference names hash to the same bucket in the hash table. This will cause the lookup process for each reference to take linear time on the amount of references in the document, and with enough link references to lookup, the end result is a pathological O(N^2) that causes medium-sized documents to finish parsing in 5+ minutes. To avoid this issue, we propose the present commit. Based on the fact that all reference lookup/resolution in a Markdown document is always performed as a last step during the parse process, we've reimplemented reference storage as follows: 1. New references are always inserted at the end of a linked list. This is an O(1) operation, and does not check whether an existing (duplicate) reference with the same label already exists in the document. 2. Upon the first call to `cmark_reference_lookup` (when it is expected that no further references will be added to the reference map), the linked list of references is written into a fixed-size array. 3. The fixed size array can then be efficiently sorted in-place in O(n log n). This operation only happens once. We perform this sort in a _stable_ manner to ensure that the earliest link reference in the document always has preference, as the spec dictates. To accomplish this, every reference is tagged with a generation number when initially inserted in the linked list. 4. The sorted array is then compacted in O(n). Since it was sorted in a stable way, the first reference for each label is preserved and the duplicates are removed, matching the spec. 5. We can now simply perform a binary search for the current `cmark_reference_lookup` query in O(log n). Any further lookup calls will also be O(log n), since the sorted references table only needs to be generated once. The resulting implementation is notably simple (as it uses standard library builtins `qsort` and `bsearch`), whilst performing better than the fixed size hash table in documents that have a high number of references and never becoming pathological regardless of the input.
