Marc Campbell commented on DOXIA-554: ------------------------------------- [~vsch] The following can be added to "doxia-modules/doxia-module-markdown/pom.xml" to set the enforcer enforceBytecodeVersion to 1.7 for the doxia-module-markdown. {code:xml} <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-enforcer-plugin</artifactId> <executions> <execution> <id>enforce-bytecode-version</id> <goals> <goal>enforce</goal> </goals> <configuration> <rules> <enforceBytecodeVersion> <maxJdkVersion>1.7</maxJdkVersion> </enforceBytecodeVersion> </rules> <fail>true</fail> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <!-- ... -> {code} I checked a build with the addition of the above code to [https://github.com/vsch/maven-doxia]. After the enforcer enforceBytecodeVersion is updated to maxJdkVersion 1.7, the next apparent hurdle is licensing. The automatic license checker {{org.apache.rat:apache-rat-plugin:0.11:check (rat-check)}} found the licenses to be "Unapproved: 2 unknown: 2 generated: 0 approved: 8". Two files in question appear to be ones that Vladimir, as the original code author and copyright holder, could adjust. {{MarkdownDoxiaNodeRenderer.java}} and {{MarkdownDoxiaExtension.java}} have: {code:java} /* Copyright (c) 2015-2016 Vladimir Schneider <...>, all rights reserved. * * This code is private property of the copyright holder and cannot be used without * having obtained a license or prior written permission of the of the copyright holder. {code} >From the report it appears the 2 unknown licenses are also the unapproved >licences. Building the module with the above enforcer change will provide the >{{rat.txt}} licensing report. > Parsing time for Markdown documents can take very long and hang site > generation > ------------------------------------------------------------------------------- > > Key: DOXIA-554 > URL: https://issues.apache.org/jira/browse/DOXIA-554 > Project: Maven Doxia > Issue Type: Bug > Components: Module - Markdown > Affects Versions: 1.7 > Reporter: Michael Benz > Attachments: maven-pom-sample-pegdown-performance.zip > > > 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]. > {quote} > 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 -- This message was sent by Atlassian JIRA (v6.3.15#6346)
