This function was missing a couple of range checks that I'm too lazy
to fix.
|
|
Avoid potential overflow and allow for different bufsize types.
|
|
|
|
Replace macro ENSURE_SIZE with inline function S_strbuf_grow_by that
checks for overflow.
|
|
cmark_strbuf_grow will never truncate a buffer.
|
|
This simplifies overflow checks.
|
|
|
|
Always add 50% on top of target size. No need for a loop.
|
|
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.

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.

On Windows, snprintf returns -1 if the output was truncated. Fall back to
Windows-specific _scprintf.
|
|
The old function called 'continue' when seeing a backslash,
but this gave incorrect results on input like:
\\*
since the next backslash would be treated as escaping the `*`
instead of being escaped itself.

MSVC doesn't support va_copy.
|
|
|
|
This reverts commit 485ef21b95e257e9d9cbcaa804c3c164f1f49a80.
Apparently the va_copy IS needed, because without this code
we get segfaults in some cases.
Closes #253.
@nwellnhof, can you have a look at this issue and comment?
I understand that this code was removed for portability reasons.
Is there an alternative solution?

Otherwise cmark's behavior varies unpredictably with the locale.
`is_punctuation` in utf8.h has also been adjusted so that everything
that counts all ASCII symbol characters count as punctuation, even
though some are not in P* character classes.

Reverts 225d720.
|
|
This isn't needed any more since we don't expose these in the API.
|
|
Inline functions must be defined in header files in order to be inlined in
other compilation units. This also fixes the MSVC build where out-of-line
versions weren't created and allows to remove the -fgnu89-inline flag.
|
|
va_copy isn't needed here. See
http://stackoverflow.com/questions/26953289
Remove it because it isn't part of C89 and not implemented by MSVC.
|
|
Fixes cross-platform issues.
|
|
Needed for C++ compatibility.
|
|
The new functions cmark_new_doc_parser,
cmark_free_doc_parser, cmark_process_line, and cmark_finish
allow you to feed lines one by one (possibly from several
files) to the parser and call finish when you're done.
This is now used in main for mulitple files.

Note: it is defined in GNU libc (Linux) and FreeBSD and OSX
sys/param.h.

It's needed in strbuf_cmp().
