2015-06-07Avoid strlen in commonmark.cNick Wellnhofer
2015-06-07Check for overflow in S_parser_feedNick Wellnhofer
Guard against too large chunks passed via the API.
2015-06-07Convert code base to strbuf_tNick Wellnhofer
There are probably a couple of places I missed. But this will only be a problem if we use a 64-bit bufsize_t at some point. Then, we'll get warnings from -Wshorten-64-to-32.
2015-06-07Change return type of cmark_strbuf_lenNick Wellnhofer
2015-06-07Missing bounds checks in buffer.cNick Wellnhofer
2015-06-07Remove unused function cmark_strbuf_attachNick Wellnhofer
This function was missing a couple of range checks that I'm too lazy to fix.
2015-06-07Fix check in cmark_strbuf_vprintfNick Wellnhofer
Avoid potential overflow and allow for different bufsize types.
2015-06-07Check for negative lengths in buffer.cNick Wellnhofer
2015-06-07Check for overflow when growing strbufsNick Wellnhofer
Replace macro ENSURE_SIZE with inline function S_strbuf_grow_by that checks for overflow.
2015-06-07Remove useless code in cmark_strbuf_growNick Wellnhofer
cmark_strbuf_grow will never truncate a buffer.
2015-06-07Account for null terminator in cmark_strbuf_growNick Wellnhofer
This simplifies overflow checks.
2015-06-07Check for overflow in cmark_strbuf_growNick Wellnhofer
2015-06-07Simplify oversizing of strbufsNick Wellnhofer
Always add 50% on top of target size. No need for a loop.
2015-06-07Use custom type bufsize_t for string buffer sizesNick Wellnhofer
This makes it easier to change the type later. No functional change. The rest of the code base still has to be adjusted to use the new type. Also add some TODO comments in buffer.c.

Abort on strbuf errors
2015-06-07Updated changelog.John MacFarlane
2015-06-07Abort on strbuf errorsNick Wellnhofer
Users of the strbuf API are supposed to check for an OOM condition after appending to strbufs, but: * This is never done in the whole code base. * The implementation was flawed because only `ptr` was set to the OOM value without adjusting `size` and `asize`. After an error, subsequent calls could very well lead to segfaults, contrary to the documentation. Change the code to always abort on errors with a message printed to stderr. The only alternative is to propagate errors throughout the whole library which seems infeasible.

2015-06-06Factored out `S_find_first_nonspace` in `S_proces_line`.John MacFarlane
Added fields `offset`, `first_nonspace`, `indent`, and `blank` to `cmark_parser` struct. This just removes some repetition in the code.

2015-06-03Revised "add newline to end if missing" for performance.John MacFarlane
From btrask's alternate code in the comment on https://github.com/jgm/cmark/pull/18. Note: this gives a 1-2% performance boot in our benchmark, probably enough to make it worth while.
