preview/pdfjs renders blank pdf documents

[lurodrig]

Hello there,

FROM alfresco/alfresco-governance-share-community:7.1.0

How to reproduce it:

1. Take this pdf from pdf completely rendered blank mozilla/pdf.js#9285
2. Uploading to any of your sites, e.g. /myfiles
3. Check the uploaded document: share/page/document-details?nodeRef=workspace://SpacesStore/XXXXX
4. Document renders blank

Problem: the pdfjs used by /share is rendering blank pdf documents:

Workaround:

1. Upgrade version of pdfjs
2. We included the above dockerfile as a builder in our custom one for share like this FROM pdfjs-build:1.0.0 as pdfjs-builder
3. Apply this patch to the PdfJs.js in share all kudos to Axel, thanks!

# Update pdfsjs (see docker-pdfjs-builder/Dockerfile)
# This last pdfjs version requires some hacks in the alfresco's pdfjs script
RUN rm $TOMCAT_DIR/webapps/share/components/preview/PdfJs-min.js
COPY preview/PdfJs.js $TOMCAT_DIR/webapps/share/components/preview/PdfJs.js
# Remove the alfresco built-in one
RUN rm -fr $TOMCAT_DIR/webapps/share/components/preview/pdfjs
# Copy the pdfjs "artifact" created in the builder container
COPY --from=pdfjs-builder /tmp/pdfjs $TOMCAT_DIR/webapps/share/components/preview/pdfjs

It would be very cool if you guys could include a patch in a future release :)

Thanks in advance,

Luis
