Subject: Re: [docbook-apps] Olinks failing -- CaseA NOT matched, No case matchedfor lang 'en' -- database build process
Hi again,
No one else seems to have experienced an issue like this, so apologies
for posting to the list if this isn't of general interest.
Bob Stayton suggests that the problem is in the olinkdb.xml file, and my
research shows that the most significant change between the time the
olinks worked and the time when they all failed is a change in the way
the olinkdb.xml is generated, and its location. The olinkdb.xml changed
from a hand-built file to an auto-generated file, and moved to a
higher-level etc directory. It used to live (until two months ago) in
DotOrg/Khelp with the global Makefiles and customization layer. Now the
olinkdb.xml is generated automatically by code that checks to see which
of the Kavi applications are installed on the website.

Here's that info. Let me know if there are any omissions.

and local targetdbs----------------

--------------In case this helps, here are some changes in the
customization layer----------------
Local Makefiles call kavi_chunk.xsl, which imports kavi_docbook.xsl and
html/chunk-common.xsl, and includes html/manifest.xsl.
Here is a comment from kavi_docbook.xsl:
<!-- Instead of including chunk.xsl as normal here, we do the
includes that stylesheet does by hand, since we need to override
some things.
-->
kavi_chunk.xsl comment:
the chunk-element-content template from chunk-common.xsl is overwritten
so we only get the stuff between the body tags.
--------------error messages from 'make html' process after adding
debugging messages----------------
This make operation is performed at the local level against the test
files. Before doing this, the target.dbs and html here and in the
glossary directory (which contains the targets of these olinks) were
deleted then regenerated. This is running against the existing
olinkdb.xml, which was generated with the 'make all' or 'make olinks'
command in the top-level help directory DotOrg/Khelp.

-------------comments and questions-------------------
Comments:
The error is thrown as the process leaves the one if statement in
kavi_docbook.xsl, but the actual error may have been encountered further
upstream.
There are very few changes in kavi_docbook.xsl, and the sections above
the chunking section are completely unchangd. The chunking section is
new here and the encoding in this section was recently changed from
UTF-8 to ISO8859-1.
QUESTIONS:
1) collect.xref.targets is set to 'only' in Makefile.inc, which is
included by the local Makefiles. CVS shows it has always been this way
(and the olinks used to work), and setting the value to 'yes' as a test
didn't make the olink process work, but perhaps I was only generating
target.dbs and html and didn't regenerate the olinkdb.xml. Can this be
ruled out as the problem?
2) The error message suggests that a language mismatch occurs during
olink processing. The section just above the if clause calls the
template named language.attribute. Language isn't set anywhere in our
customization layer, although 'en' appears to be specified here in the
xml documents themselves:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE glossary PUBLIC "-//OASIS//DTD DocBook XML V4.2//en"
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd";>
The error about CaseA refers to a section of /common/olink.xsl:
<!-- Customize these cases if you want different selection logic -->
<xsl:variable name="CaseA">
<!-- targetdoc.att = not blank
targetptr.att = not blank
-->
<xsl:if test="$targetdoc.att != '' and
$targetptr.att != ''">
<xsl:for-each select="$target.database">
<xsl:variable name="key"
select="concat($targetdoc.att, '/',
$targetptr.att, '/',
$target.lang)"/>
<xsl:choose>
<xsl:when test="key('targetptr-key', $key)/@href != ''">
<xsl:value-of select="$key"/>
<xsl:if test="$olink.debug != 0">
<xsl:message>Olink debug: CaseA matched.</xsl:message>
</xsl:if>
</xsl:when>
<xsl:when test="$olink.debug != 0">
<xsl:message>Olink debug: CaseA NOT matched</xsl:message>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:if>
</xsl:variable>
3) Could encoding be an issue? There is some variation. The files are in
UTF-8. The olinkdb.xml lacks encoding in the declaration. Output in
chunks is set to ISO8859-1
4) Or is something in the olink or targetdb build definitely the issue?
If it isn't visible in the info I've provided, can someone (esp. Bob)
point me at gaps in the info...any suggestions for tests, etc?
Otherwise, I guess my next step is to roll all the changes back to the
beginning of the year and see if the olink builds succeed, then begin
reintroducing the changes incrementally until something breaks.
Regards to all; thanks especially to Bob,
Teya
