Python interface seems to not work.

[fake-name]

I'm trying to get gumbo to work with python on ubuntu 14.04, and not having much work.

I built and installed gumbo by cloning the master branch:

Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

I patched the import to gumboc_tags by just copying the contents of that file (it's just a single big array) into gumboc.py, then fixed the library search path issue (I just hardcoded the library path to "/usr/local/lib/libgumbo.so.1.0.0"), and it then imports, but gumbo.soup_parse (which is what I want) doesn't seem to be present:

>>> import gumbo
>>> gumbo
<module 'gumbo' from '/usr/local/lib/python3.4/dist-packages/gumbo-0.10.1-py3.4.egg/gumbo/__init__.py'>
>>> gumbo.soup_parse
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'soup_parse'
>>>

I also attempted to see if the version in PyPi would work, and it's non-functional after install for python3 (my app is python 3, I tested python 2 just to be thorough).

[fake-name]

Ok, at least part of this is #343, ~~and from . import gumboc_tags fixes that (I could swear I tested that before just moving the contents of gumboc_tags).~~~

The fix suggested there does not work:

>>> import gumbo
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.4/dist-packages/gumbo/__init__.py", line 33, in <module>

  File "/usr/local/lib/python3.4/dist-packages/gumbo/gumboc.py", line 29, in <module>
    from . import gumboc_tags
ImportError: cannot import name 'gumboc_tags'

Anyways, the library path search is still completely broken. What system did a normally installed gumbo library ever work on?

It looks like something, somewhere, is failing to link libpthread.

I have no idea where to look with the build process, though. I'm only vaguely familiar with make, and have no idea about autoconf.

Yes, python part doesn't work under py3.4. Multiple import errors, shitty formatting style, wrong c library loading code, multiple errors on trying to parse something using adapters. And these errors seem to be omni-versional, not related to py3.

[kevinhendricks]

Sigil has a fixed version for python 3.4 along with a new beautiful soup 4 adapter that works with the version of the gumbo parser that has been specially modified for use inside Sigil. I am sure it could be easily fixed/adapted for the official gumbo parser. Let me know if you need or want a copy and I'll take a shot at adapting what we have to work here.

@kevinhendricks

Sigil

Always wondered how can I find these specific about-demonic pictograms.
Are you talking about this code: https://github.com/Sigil-Ebook/sigil-gumbo/tree/master/python/gumbo ? Personally I'm interested to have working html5lib adapter, thanks for pointing onto possible working version. Fast inspection didn't make me happy though, it still has bad importing requiring adding changes in PYTHONPATH to work. Since it has __init__.py it tries to be a python package and it must use relative imports to behave well.

[kevinhendricks]

That version is for specific use inside of Sigil's plugin python 2.7 and python3.4 environment. It is set up to work with BS4 (also used internally by Sigil) not html5lib but the bulk of it should be adaptable.

If it helps the sigil-python code we actually deploy to interface to gumbo is here:

https://github.com/Sigil-Ebook/Sigil/tree/master/src/Resource_Files/plugin_launchers/python

See:

sigil_gumboc.py
sigil_gumboc_tags.py
sigil_gumbo_bs4_adapter.py

I'm rewriting the binding here https://github.com/neumond/scutigera/tree/master/scutigera/gumbo
Decided to throw away overly complex Enum class, leaving in gumboc almost pure C interface.
Wiped gumboc_tags file, no need to keep it, it can be dynamically obtained from dll.
Now trying to write adapter which will conform html5lib test suite. Seems like gumbo fails in several tests, need some time to investigate these issues better. Most of tests are successful though.

Is it worth to use CFFI or Cython instead ctypes? PyPy recommends using CFFI (looks like they bet on JIT to optimize interaction) while Cython advertised in multiple articles across internet as fastest possible solution after pure CPython extension.

[neumond]

Hmm. Now the question is what encoding does gumbo consider to use internally. It accepts a buffer of bytes. Some of tests fail at decoding output as utf-8. Even if it treats input as ascii, which is enough to do HTML parsing, it does need some encoding choice to decipher html entities like 䔡

[kevinhendricks]

gumbo only works with properly utf-8 encoded html files. if an html file has any other encoding, it must be converted to utf-8 before being parsed by gumbo. See the readme on this site for details. Also the source being parsed must continue to exist be stored in memory as pointers into the original source exist in the parsed tree.

[neumond]

it must be converted to utf-8 before being parsed by gumbo

Exactly as I supposed it to be. Well, for test FOO&#111111111111 gumbo over ctypes binding outputs text node with b'FOO\xc7'.
If I hack prettyprint example to output char codes:

      // line 195
      for (int j = 0; j < 8; j++){
          std::cout << ((int) child->v.text.text[j]) << std::endl;
      }

It's b'FOO\xc7\n' (70,79,79,-57,10,0). Using html5lib parser I get unicode point 65533 or b'FOO\xef\xbf\xbd' in utf-8.

Magic.

By the way, how can I check html5lib test suite, some tests look unreasonable for me. Id est gumbo works properly and html5lib test expects wrong, e.g. for noscript tag test.

UPD. It is an interesting character (65533) http://www.fileformat.info/info/unicode/char/0fffd/index.htm

REPLACEMENT CHARACTER
used to replace an incoming character whose value is unknown or unrepresentable in Unicode

UPD2. Very interesting :)

b'FOO\xc7'.decode('utf-8', errors='replace').encode('utf-8')
b'FOO\xef\xbf\xbd'

UPD3. Now it's better.

168 failed, 15944 passed, 3056 skipped
124 failed, 15988 passed, 3056 skipped

[gsnedders]

b'FOO\xc7'.decode('utf-8', errors='replace').encode('utf-8')

As far as I'm aware, Gumbo's output shouldn't ever be invalid UTF-8. Certainly, per spec, Gumbo should be outputting U+FFFD for that, and definitely shouldn't be output something broken!

By the way, how can I check html5lib test suite, some tests look unreasonable for me. Id est gumbo works properly and html5lib test expects wrong, e.g. for noscript tag test.

A good starting point nowadays is look what your favourite browser does on the Live DOM Viewer though that doesn't work in the case of noscript tests with #script-off. Otherwise, uh, the best things are likely either asking in #whatwg on freenode or filing a bug on html5lib-tests. Or just ping me here.

[neumond]

Gumbo should be outputting U+FFFD for that

Ok, I think its time to dig gumbo code to repair this. Who knows maybe in some cases gumbo will output valid utf8 where it must output replacements.

Regarding noscript, that's one of obscure things I didn't know about. Considering this example

<p id="status"><noscript><strong>A</strong></noscript><span>B</span></p>

If I inspect DOM in firefox with javascript turned on I have <noscript> node with inner text "<strong>A</strong>". But if I disable javascript I have separate node of <strong> with text "A". Looks like gumbo behaves as if I disable javascript, but html5lib test expects it to be as if I enable javascript. There should be parameter for parse I guess.

[kevinhendricks]

So if you use a numeric entity like & # 111111111111 ; (which takes minimum 5 bytes to even represent as hex) or any other illegal unicode code point, the spec says to output UxFFFD? Is that right?

I know gumbo does output proper utf-8 encoded values for legal numeric entities.

For example: & # x F F F D ; results in the proper utf-8 byte string of 0xEF 0xBF 0xBD in the serialized output.

[kevinhendricks]

The problem is overflow of an int type in src/char_ref.c

int codepoint = 0;
  bool status = true;
  do {
    codepoint = (codepoint * (is_hex ? 16 : 10)) + digit;
    utf8iterator_next(input);
    digit = parse_digit(utf8iterator_current(input), is_hex);
  } while (digit != -1);

  if (utf8iterator_current(input) != ';') {
    add_codepoint_error(
        parser, input, GUMBO_ERR_NUMERIC_CHAR_REF_WITHOUT_SEMICOLON, codepoint);
    status = false;
  } else {
    utf8iterator_next(input);
  }

  int replacement = maybe_replace_codepoint(codepoint);
  if (replacement != -1) {
    add_codepoint_error(
        parser, input, GUMBO_ERR_NUMERIC_CHAR_REF_INVALID, codepoint);
    *output = replacement;
    return false;
  }

  if ((codepoint >= 0xd800 && codepoint <= 0xdfff) || codepoint > 0x10ffff) {
    add_codepoint_error(
        parser, input, GUMBO_ERR_NUMERIC_CHAR_REF_INVALID, codepoint);
    *output = 0xfffd;
    return false;
  }

Before each iteration for adding the next char digit it needs to check and prevent overflow of the codepoint value (anything greater than 0x10ffff) while still continuing to consume the bad numeric entity until it gets to a non-digit.

If you look at 111111111111 as hex (0x19debd01c7) it overflows an int type and the last byte value is the one you are seeing in the output (0xc7).

The overflow prevents this snippet of code from working:

if ((codepoint >= 0xd800 && codepoint <= 0xdfff) || codepoint > 0x10ffff) {
    add_codepoint_error(
        parser, input, GUMBO_ERR_NUMERIC_CHAR_REF_INVALID, codepoint);
    *output = 0xfffd;
    return false;
  }

The problem is char_ref.c is preprocessed to make char_ref.rl for speed, so once a proper fix is made, that the char_ref.rl will have to be recreated.

Hope this helps.
