pycups patch for writeRequestData and binary files
by Doug Reynolds 23 Jun '16

23 Jun '16

Hello all, For pycups method, cups.writeRequestData, there is a bug that will corrupt binary data when streamed through this method. This python code will expose the problem: import cups x = None conn = cups.Connection() id = conn.createJob('printer', 'blah', { 'document-format': cups.CUPS_FORMAT_AUTO }) conn.startDocument('printer', id, 'asdfasd', cups.CUPS_FORMAT_AUTO, 1) with open('test.pdf', 'rb') as f: while True: x = f.read(1024) if len(x): conn.writeRequestData(x, len(x)) else: break conn.finishDocument('printer') The printer will print out a sheet with the text: PDF Error 10: PostScript: Error: IOERRORAssert FaileD: rc == curStrLen If you take the print queue down and print the same file with lpr -P printer, the md5sums in /var/spool/cups are different. Each lpr command produces a queued file with the same hash as the original file. Each file printed through the API will have a different sum each time. The issue is caused by this line in the code: buffer = strdup(PyBytes_AsString (buffer_obj)); The strdup detects a null in the Python byte array and ends the copy. This causes a buffer overrun when "status = cupsWriteRequestData(self->http, buffer, length);" is called. This is because the buffer might only have 120 bytes in it, and the length is equal to, says, 8192. I switched over to memcpy, and malloc'd a separate buffer. I choose memcpy as this method is not overrun safe. The caller must mind his or her own buffer size. The method now works with jpgs, pdfs, and regular text files. Feel free to make my code better as my C is a bit rusty. Doug

system-config-printer now on GitHub
by Tim Waugh 19 May '15

19 May '15

I've moved the system-config-printer repository to GitHub: https://github.com/twaugh/system-config-printer Please report problems as GitHub issues. Of course, pull requests are welcome. ;-) I've enabled the Travis CI service to check that 'make distcheck' works, although currently most of the tests are skipped due to lack of pycups availability in the test environment. The other thing I've enabled is Landscape.io for code quality checking. The current health report is pretty abysmal, and it would be great to have help cleaning up the identified problems! Currently, pycups and pysmbc remain at fedorahosted.org. Tim. */

Where to submit translations?
by Alexander Potashev 28 Apr '15

28 Apr '15

Hi, I've found at least a couple of problems in Russian translations and I'm looking for a way to solve them in the future releases of system-config-printer. The thing [1] I presume to be the project homepage points me to Transifex, but the relevant project [2] is frozen there. Where are translations pulled from nowadays?

by philippe makowski 17 Mar '15

17 Mar '15

Hi, can someone help me to find how to correct this bug (https://bugs.mageia.org/show_bug.cgi?id=14981)? "For the default printer, a green check mark is placed on the printer icon. In Cauldron's version, it shows two check marks (top left and right) and some visual artifacts (bottom half of the icon) on the icon." any clue on what I have to look for ? Thanks
