Slackware 14.0slackware-14.0
Wed Sep 26 01:10:42 UTC 2012 Slackware 14.0 x86_64 stable is released! We're perfectionists here at Slackware, so this release has been a long time a-brewing. But we think you'll agree that it was worth the wait. Slackware 14.0 combines modern components, ease of use, and flexible configuration... our "KISS" philosophy demands it. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. Thanks to everyone who helped make this happen. The Slackware team, the upstream developers, and (of course) the awesome Slackware user community. Have fun! :-)

+Description:
+ QPainter together with QPrinter leaves a lot of temporary files in
+ /tmp with every printout. That is a problem for embedded devices,
+ which have not such a large /tmp-partition. We are using 80 MByte as
+ tmpfs, i.e. in RAM. After some printounts cups deactivates the printer
+ because there is no space to copy the temporary files to /tmp.
+
+ What happened: In QPdfBaseEnginePrivate::openPrintDevice() noone
+ remembers the file descriptor opened by tempFile() which is a call to
+ the cups library to cupsTempFile()
+
+ Later in closePrintDevice the check for fd<0 fails, so no one closes
+ the file descriptor. If you later remove the file, the descriptor is
+ still open and cannot removed until you close the application.
+
+ If you print 20 times and more during your application is running and
+ you print out large files (complicate forms with a lot of elements
+ produces files with 3-4 MByte) your temporary file can be full, but
+ you don't see (with ls) files in it.
