-------------------------------------------
Summary: Creation date set on FOUserAgent is not used for
xmp:MetadataDate and the file ID
Key: FOP-3367
URL: https://issues.apache.org/jira/browse/FOP-3367
Project: FOP
Issue Type: Bug
Components: renderer/pdf
Affects Versions: 2.12
Reporter: Juan Manuel Méndez Rey
Attachments:
0001-FOP-Use-the-user-agent-creation-date-for-MetadataDate-and-file-ID.patch
[PATCH]
When a creation date is set with FOUserAgent.setCreationDate(), FOP uses it for
/CreationDate and xmp:CreateDate, but xmp:MetadataDate and the date hashed into
the trailer /ID still come from the clock. So two runs with the same input and
the same creation date give different PDFs.
In FOP-2854 the advice was to set the dates through the FOP API. This patch
makes the API date apply everywhere. It adds no environment variable or new
option.
* IFRenderer and PDFRenderingUtil: MetadataDate is the creation date when one
is set, the current time otherwise.
* FileIDGenerator: hashes the document creation date instead of the current
time.
* New test PDFCreationDateTestCase: renders the same FO twice with a fixed
creation date. Both cases fail on main (1301bcf) and pass with the patch.
When no creation date is set, nothing changes. The full fop-core suite passes
(3731 tests) and checkstyle reports no violations.
