Yorick Peterse fd2f727183 Only set explicit ivars in the lexer. 2014-05-15 19:48:18 +02:00
Yorick Peterse 44bf1dd1ca Split up handling of element names/namespaces.
This is now split up on Ragel level, simplifying the corresponding Ruby code.

Yorick Peterse 723a273e4f Enforce symbols for element attributes.
This comes with a little bit of memory overhead but this should be minor in
most cases.

Yorick Peterse f4b9bbd4ac Removed lazy way of setting instance variables.
This process is quite a bit slower compared to setting instance variables
directly.

Yorick Peterse 043ea9a366 Fall back to ps in the profiler.
If the /proc filesystem doesn't exist we'll fall back to using the `ps` shell
command.

Yorick Peterse 1b58723e7d Removed stdioh. #include.
This header is also not needed.
2014-05-11 21:06:55 +02:00
Yorick Peterse e2b9fc75ca Removed #include for malloc.h
Apparently some OS' move this to malloc/malloc.h. Since it's not needed lets
just get rid of it.

Thanks to @avdi for bringing up on how to do this when using rule() blocks.

Yorick Peterse fe74d60138 Manually bootstrap JRuby after all.
After discussing this with @headius I've decided to do this the manual way
anyway. Apparently the basic load service stuff is deprecated and not very
reliable.

Yorick Peterse 3c621bf22e Removed the manifest file + task.
Using a Dir.glob() is much easier when dealing with a bunch of generated files.

Yorick Peterse ee78b2c382 Don't redefine namespaces in C.
The Oga::XML namespace should be set up by Ruby, not by C.

Yorick Peterse 3afef5f7cc Lexer support for JRuby.
JRuby now passes all tests. Benchmark wise it completes the big XML benchmark
in about 500-600 milliseconds.

Yorick Peterse f25f8a3d15 Break up the Ragel C grammar.
The grammar is now broken up in to a base lexer and a C lexer. This allows the
same grammar to also be used in the Java code.

Yorick Peterse f39fe5d857 JRuby lexer boilerplate with actual input.
This doesn't actually lex anything just yet but at least the input from Ruby is
in place.

Dumbass.

Yorick Peterse 2652bc0103 Removed Cliver as a dependency.
Since I'm not using any Ragel version specific features it's not really needed
to check for the version.

Yorick Peterse c30d3a7627 Half-assed JRuby boilerplate.
Blowing my brains out over getting this fat pig to do what I want but we're
getting there.

Yorick Peterse 2b3a6be24d Use liboga as a prefix in the C code.
Namespaces? What are those?

Yorick Peterse 335f3cc6d6 Use rb_enc_str_new instead of rb_enc_str_new_cstr.
The latter in combination with strndup() would leak large amounts of memory.

Yorick Peterse 2689d3f65a Initial setup using a C extension.
While I've tried to keep Oga pure Ruby for as long as possible the performance
of Ragel's Ruby output was not worth the trouble. For example, lexing 10MB of
XML would take 5 to 6 seconds at least. Nokogiri on the other hand can parse
that same XML into a DOM document in about 300 miliseconds. Such a big
performance difference is not acceptable.

To work around this the XML/HTML lexer will be implemented in C for
MRI/Rubinius and Java for JRuby. For now there's only a C extension as I
haven't read up yet on the JRuby API. The end goal is to provide some sort of
Ragel "template" that can be used to generate the corresponding C/Java
extension code. This would remove the need of duplicating the grammar and
associated code.

The native extension setup is a hybrid between native and Ruby. The raw Ragel
stuff happens in C/Java while the actual logic of actions happens in Ruby. This
adds a small amount of overhead but makes it much easier to maintain the lexer.
Even with this extra overhead the performance is much better than pure Ruby.
The 10MB of XML mentioned above is lexed in about 600 miliseconds. In other
words, it's 10 times faster.
