Add xml:space="preserve" in XML output when appropriate
|
|
Closes #263.
|
|
Newer versions of CMake attempt to query the system for information about the VS
2017 installation. Unfortunately, this query fails on non-Windows systems when
cross-compiling:
cmake_host_system_information does not recognize <key> VS_15_DIR
CMake will not find these system libraries on non-Windows hosts anyways, and we
were silencing the warnings, so simply omit the installation when
cross-compiling to Windows.

These affect both parsing and writing commonmark.
|
|
With current HTML escaping, sometimes we may produce an XML tag like
<code_block> </code_block>
Many XML parsers consider these spaces insignificant and strip them
out but we need this. There's actually a test case like this in
spec.txt (search "A code block can have all empty lines as its
content:") and without proper hinting, an external xml->html converter
will fail the spec.
XML standard covers this case. If xml:space is "preserve", then
whitespaces are significant and should be kept. Add this hint for
text, code, code_block, html_inline and html_block tags.

Added regression test.

We were needlessly redoing things we'd already done.
Now we skip the work if the first nonspace is greater
than the current offset.
This fixes pathological slowdown with deeply nested
lists (#255). For N = 3000, the time goes from over
17s to about 0.7s.
Thanks to @mity for diagnosing the problem.

This fixes a recently added failing spec test case.
Previously spaces were being allowed in unquoted attribute
values; no we forbid them.

Fixes installation error under some CMake versions, notably kalakris'
CMake backport often used with Travis.

Due to a mistake, 0.28.1 installed libcmark.a into include/.
Closes #238.
|
|
For some reason this wasn't getting set in processing
libcmark.pc.in, and we were getting the wrong entry in libcmark.pc.
(See #236)
The new approach sets an internal libdir variable to
lib${LIB_SUFFIX}. This variable is used both to set the
install destination and in the libcmark.pc.in template.
Closes #236.
However, I'd welcome comments from @juhp who originally
added CMAKE_INSTALL_LIBDIR in #185. I think that the new
system should work fine with Fedora, since LIB_SUFFIX will
be set appropriately, but some testing is in order.

This option was added in 04726a7 (Added `CMARK_OPT_VALIDATE_UTF8`
option. - 2015-06-16) but not "documented".

Use unsigned integer when shifting
|
|
A UBSAN warning can be triggered when handling a long sequence of backticks:
src/commonmark.c:98:20: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
which can be triggered by:
```
| a | b |
| --- | --** `c```````````````````````````````- |
| c | `|d` \| e |
```
|
|
A UBSAN warning can be triggered because the link title is an empty string:
src/inlines.c:113:20: runtime error: null pointer passed as argument 2, which is declared to never be null
which can be triggered by:
```
[f]:_
[f]
```
The length of the memcpy is zero so the NULL pointer is not dereferenced but it
is still undefined behaviour.
|
|
This also brings the code into closer alignment with the wording
of the spec.
See jgm/CommonMark#467.

We got an array overflow in enumerated lists nested more than
10 deep with start number =/= 1.

This commit also ensures that we don't try to set `enum_` counters
that aren't defined by LaTeX (generally up to enumv).
Closes #210.

This can be run locally with `make libFuzzer` but the harness will be
integrated into oss-fuzz for large-scale fuzzing.

Note, however, that this may not be needed at all:
the old code would have gone into an infinite loop
if the delimiter stack were not already freed.
If we can prove that the delimiter stack is empty
at this point, we could remove this; on the other hand,
it may not hurt to keep it here defensively.
Closes #189.
