James R. Barlow 27a3813207 Recover input filename from symlink on error message 
The recent commit to accept files from stdin broken the feature of
returning the input filename on an error, returning the temp filename
instead, which is confusing.

James R. Barlow d32ea8d0dd Remove dead code from qpdf merge + PyPDF2 metadata patching 
I tried "qpdf merge + PyPDF2 metadata patching" first. The problem is
that PyPDF2 produces a 1.3 by default and generally I have less
confidence it.

New approach is to stuff the Document Info metadata in the first page
with PyPdf2, cross fingers and use qpdf to merge. It's not quite as
clean and might harm the first page, but it's better than shipping
files produced by PyPDF2.

James R. Barlow 5c99acf6d1 Experimental change to use qpdf to merge files (disables Ghostscript) 
All but one tests pass, test_input_file_not_a_pdf

Not sure if PyPDF2 metadata generation will mangle the first page.

James R. Barlow ebe68de4ff Functional qpdfmerge with PyPDF2 for DocumentInfo block 
Tests mostly passing. For the moment this is the new default.

Although PyPDF2 produces a PDF-1.3 which will be wrong for some contents
and possible should be repaired with qpdf. Again.

Looks like it could work better to merge PyPDF2 and fix everything
with qpdf.

James R. Barlow d257c83520 Most tests were failing at split_pages() 
It seems that ruffus sometimes decides to send a ['inputfile.pdf']
instead of a bare string.

allowing or disallowing strings.

James R. Barlow fef35e4eb2 Fix handling of DPI for rare case of JPEG recompression after deskew/clean 
This test is exercised by page 4 of multipage.pdf. If all images are
JPEGs, and one of deskew/clean removes DPI information, make sure that
we can get the right information back and that the DPI stays square.

James R. Barlow b3fcf24a26 Refactor DPI: fix regressions in test suite 
Some called functions are particular about the data format of DPI and
don't like to deal with the Decimal() returned by PyPDF2. Convert to
float and int where needed.

James R. Barlow 16e4d342d2 Bug fix: --force-ocr should still run on pages with no images 
Useful for people who want to reprocess text.

This also requires --oversample because DPI is undefined. To be fixed
in next commit.

James R. Barlow fe14cb57c0 Fix ruffus exception output 
I found this issue in ruffus 2.6.3
https://github.com/bunbun/ruffus/issues/65
also discussed here
https://github.com/bunbun/ruffus/pull/67

ruffus 2.6.3 RethrownJobError don't follow the normal conventions and
so its exception causes problems when they cross process boundaries.
This change carefully examines the various forms of ruffus exception
objects that can appear in 2.6.3 and parses them more carefully. It
also removes any direct posting of the exception to the logger because
this triggers another serializing of the exception object, mutating it
further.

James R. Barlow d30a879e2d Fix test suite by running select_image_for_pdf unconditionally 
The purpose of this change that caused the problem was a minor
optimization for the tesseract renderer path that had it pull an image
from select_image_for_pdf so that it could use a JPEG instead of PNG,
instead of taking it from preprocess_clean where it would only get a PNG
and make large files.
