biswajit updated PDFBOX-4601:
-----------------------------
Description:
in AWS lambda pdf merge giving error as
{{Error in pdf consolidation: Expected scratch file size of 196608 but found
192512.}}
*Code:*
{{PDFMergerUtility pdfMerger = new PDFMergerUtility();}}
\{{ pdfMerger.addSources(sources);}}
\{{
pdfMerger.setDestinationStream(mergedPDFOutputStream);}}{{pdfMerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());}}
both InputStream and OutputStream are ByteArrayInputStream and
ByteArrayOutputStream. AWS Lambda environment has 512MB space available only
for /tmp partition. This could be an issue or not I am not sure. And AWS lambda
do not permit other directory than /tmp partition to create files.
And while reading into the code I found below piece of code which I think
always be true. Because if you add some constant amount to an integer that will
always be constant amount greater than its original value
in ScratchFile.java => enlarge() method:
{{if (pageCount + ENLARGE_PAGE_COUNT > pageCount)}}
\{{ {}}
\{{ fileLen += ENLARGE_PAGE_COUNT * PAGE_SIZE;}}
{\{ raf.setLength(fileLen);}}
{\{ freePages.set(pageCount, pageCount + ENLARGE_PAGE_COUNT);}}
\{{ }}}
