[jira] [Commented] (DOXIA-554) Parsing time for Markdown documents can take very long and hang site generation

["Vladimir Schneider (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DOXIA-554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15895878#comment-15895878 ] 

Vladimir Schneider commented on DOXIA-554:
------------------------------------------

I encountered a show stopper. Doxia requires Java6 compatibility and flexmark-java requires Java7. 

I converted the source to Java6 but BitSet in JDK7 is missing some BitSet methods. Additionally,  org.nibor.autolink used by the autolink extension is byte code level 7 not 6.

The missing BitSet methods I can get around but the byte code level of the autolink dependency would require rewriting the extension without the library. 

Considering that JDK6 has reached EOL in 2012 is there a good reason why Doxia is still requiring JDK6 compatibility?

> The parsing time for Markdown documents can take very long and hang site generation when e.g. long tables are being generated.
> The author of pegdown has marked the pegdown project deprecated since 2016-12-14 [pegdown.org|https://github.com/sirthias/pegdown/] and advises to switch to [flexmark-java|https://github.com/vsch/flexmark-java].

> The project is essentially unmaintained with tickets piling up and crucial bugs not being fixed.
> pegdown's parsing performance isn't great. In some cases of pathological input runtime can even become exponential, which means that the parser either appears to "hang" completely or abort processing after a time-out.
> {quote}
> Since the parsing timeout was increased in DOXIA-498 it is now possible to "hang" the site creation with a longer table like the one in this example.
> In case this sample is rendered using version 3.3 of the maven site
