- authentication by smartcard and USB stick
CUPS backend for printing from X2Go.
Update Information:
* New upstream version (3.0.1.2):
- cups-x2go{,.conf}: port to File::Temp. Use Text::ParseWords to split up the ps2pdf command line correctly. Don't use system() but IPC::Open2::open2(). Capture the ps2pdf program's stdout and write it to the temporary file handle "manually". Should fix problems reported by Jan Bi on IRC.
- cups-x2go: fix commented out second ps2pdf definition to output PDF data to stdout.
* New upstream version (3.0.1.3):
- cups-x2go: import tempfile() function from File::Temp module.
- cups-x2go: only repeat the last X, not the whole ".pdfX" string (or the like.)
- cups-x2go: actually print "real" executed command instead of the "original" one with placeholders.
- cups-x2go: read output from ghostscript, don't write a filehandle to the temporary file. Fixes a hanging ghostscript call and... well... random junk, instead of a "real" PDF file.
- cups-x2go: use parentheses around function arguments.
- cups-x2go: fix binmode() call, :raw layer is implicit.
- cups-x2go: fix print call... Does not allow to separate parameters with a comma.
- cups-x2go: add correct :raw layer to binmode calls.
- cups-x2go: fix tiny typo.
- cups-x2go: read data from GS and STDIN in chunks of 8 kbytes, instead of everything at once. Handles large print jobs gracefully.
- cups-x2go: add parentheses to close() calls.
- cups-x2go: delete PDF and title temporary files automatically.
- cups-x2go: unlink PS temporary file on-demand in END block. Also move closelog to END block, because we want to print diagnosis messages in the END block.
- cups-x2go: don't use unlink() explicitly. Trust File::Temp and our END block to clean up correctly.
- cups-x2go: there is no continue in perl for stepping forward a loop. Still not. I keep forgetting that. Use next. (Partly) Fixes: #887.
- cups-x2go: use the same temp file template for PS, PDF and title files. Use appropriate suffixes if necessary when generating PDF and title temp files. (Fully) Fixes: #887.
Update to 3.0.1.1:
- Add a short README that provides some getting started information.
