Generation is slow #43

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The generation is very slow. I think docbkx is downloading
all the dtds for each file from the internet. If i remove
the dtds from the xml, generation is fast.

Hi,

are you talking about dtd definitions located in your docbook XML source files?
If yes I need to have a look at if XML catalogs are still working.
Could you tell me which version of docbkx-tools you are using?

Regards,
mimil

I noticed a similar issue, when generating the HTML documentation the process 
hangs.
I analysed the JVM with JVisualVM, the thread is stuck on network connections. 
If the
doctype is removed it works fine. The doctype used is:

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd">

There is no problem with the PDF generation.

I tried with the 2.0.9 and 2.0.10-SNAPSHOT versions.

I'm finding this to be true too with 2.0.11-SNAPSHOT.  I reproduce it very 
easily on this project: 
http://github.com/jaxzin/nexus-book

It looks like Saxon is deferring to Xerces but not passing on the URIResolver.

you are fast 2.0.11-SNAPSHOT has just 20 mins life long. Yup the issue is still 
open
and have to be investigated.

Cedric

:-) I was working on a bug fix to my patch of Issue 50 while you were 
releasing.  I figured I'd be accurate in my 
comment even if it was eerily quick.  I hope the stacktrace helps.

another thing (not related but to let you know) we also had a problem on issues
notification mailing list so I was not anymore aware of new issues (at least 
the 5
last ones)

I think the URLResolver is not properly initialized to load catalogues from
docbook-xsl and docbook-xml artifacts. Well it is from where I will start 
investigation.

Cedric,

Found the problem and attached a patch.  It turned out to be a typo in the 
resource name.

Thank you,

I will add more cases on loading catalogs located in different directories

I think we are now okay with the catalogs loading. I think the remaining 
problem here
is that there is no docbook xml artifact for docbook4.5

<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN"
"http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd" [
]>

works well offline with

<dependency>
  <groupId>org.docbook</groupId>
  <artifactId>docbook-xml</artifactId>
  <version>4.4</version>
 <scope>runtime</scope>
</dependency>

I will try to test by making docbook4.5 artifact.

Regards,
Cedric

Docbook 4.5 seems to be available on sonatype repository 
(https://repository.sonatype.org/content/groups/public/) 

    <dependency>
      <groupId>docbook</groupId>
      <artifactId>docbook-xml</artifactId>
      <version>4.5</version>
    </dependency>

The repository can be added in your pom with:

<repositories>
  <repository>
    <id>sonatype-public</id>
    <name>Sonatype Public</name>
    <url>http://repository.sonatype.org/content/groups/public</url>
  </repository>
</repositories>
