Common UNIX Printing System 1.1.20rc1

Created at 09:00 Sep 05, 2003 by mike, last modified at 14:05 Sep 05, 2003

The first release candidate for version 1.1.20 of the Common UNIX Printing System ("CUPS") is now available for download from the CUPS web site at:

    http://www.cups.org/software.php

In accordance with the CUPS Configuration Management Plan, you now have until Friday, September 19th to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

    http://www.cups.org/str.php

Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 1.1.20, so it is very important that you report any problems you identify using the form.

CUPS 1.1.20 is primarily a bug fix and performance tuning release and includes fixes for 64-bit platforms, deadlock problems in the signal handling code, PDF printing issues, web interface issues, and various operating system-specific issues. The new release also adds new CUPS API functions for reading and writing files via HTTP, performing authentication, and controlling the required PPD conformance level.

Changes in CUPS v1.1.20rc1:

        

• The scheduler now waits up to 60 seconds before
          restarting to allow active jobs to complete printing
          and pending requests to be processed (STR #226)
          
• The web interface did not work on systems where time_t
          is 64 bits (STR #262)
          
• Added backend tweeks and content-length check from Red
          Hat (STR #253)
          
• The USB backend now uses the 8255 constants instead of
          the standard constants when reporting printer status
          bits on Linux (STR #254)
          
• Added new cupsDoAuthentication(), cupsGetFd(),
          cupsGetFile(), cupsPutFd(), and cupsPutFile() functions
          to the CUPS API (STR #112)
          
• The PDF filter always scaled and offset pages; this
          caused problems under MacOS X, so now the "fitplot"
          option controls whether PDF files are scaled to fit
          within the printable area of the page (STR #250)
          
• The LPD backend did not support the port number in a
          URI (STR #247)
          
• Some filters didn't properly support boolean options
          (STR #249)
          
• Landscape PDF files were not always offset by the
          correct amount when rotating (STR #243)
          
• The scheduler could hang in a call to localtime() when
          logging messages from the signal handler (STR #242)
          
• The PDF filter no longer prints form widgets; this
          duplicates the behavior of Acrobat Reader (STR #241)
          
• cupsGetPPD() didn't handle a late termination of a
          HTTP connection with the server (STR #220)
          
• ppdOpen() did not correctly check for "*PPD-Adobe-4."
          on the first line of a PPD file. This caused incorrect
          PASS results for some PPD files (STR #233)
          
• cupsEncodeOptions() did not allow boolean options to
          use "yes" and "on" for true values (STR #227)
          
• The pstops filter only sent the TBCP exit sequence if
          it was defined in the JCLEnd attribute in the PPD file
          (STR #224)
          
• Support for more than 1024 files was broken on Solaris
          9 (STR #217)
          
• The setgroups() calls now pass in 1 group (the
          configured group) instead of 0 for compatibility with
          BSD and Darwin (STR #213)
          
• The scheduler's built-in broadcast throttling was
          ineffective since incoming packets would cause the
          next group of outgoing packets to be sent immediately
          rather than waiting for the next time slot (STR #211)
          
• Added a new ppdSetConformance() function to set the
          conformance requirements for PPD files. Currently only
          two levels are defined, PPD_CONFORM_RELAXED and
          PPD_CONFORM_STRICT, and the default is the relaxed
          level (STR #212)
          
• The IPP backend did not correctly execute the
          pictwpstops filter on OSX (STR #210)
          
• The LPD backend did not set the banner class when the
          "banner=yes" option was specified in the device URI
          (STR #209)
          
• The imagetoraster filter did not support all of the
          page device attributes (STR #208)
          
• The pdftops filter incorrectly auto-rotated pages when
          the user already had specified the proper orientation
          (STR #207)
          
• Fixed AIX shared library support (STR #201)
          
• Added support for live testing with Valgrind (STR
          #193)
          
• The CGI programs now collect the list of needed
          attributes for the class, job, and printer template
          files (STR #192)
          
• The scheduler now passes the first port that is bound
          to the local loopback or "any" addresses to the CGI
          programs rather than the port that the browser
          connected to (STR #103)
          
• The cupstestppd program now checks for bad
          JobPatchFile attributes and incorrect versions of the
          Manufacturer attribute for HP printers (STR #155)
          
• The filter makefile incorrectly installed
          libcupsimage.a in the filter directory (STR #180)
          
• The scheduler did not verify that the job history
          files define the job-priority and
          job-originating-user-name attributes (STR #178)
          
• The pstops filter didn't handle poorly-formed binary
          PostScript files that had CTRL-D's in them (STR #156)
          
• The ppdOpen*() and cupsLangGet() functions did not
          make a copy of the old locale strings when using the
          POSIX locale when reading files, which apparently
          caused problems with some implementations of the
          standard C library. (STR #159)
          
• The pdftops filter did not work properly with some
          embedded Type1C fonts (STR #177)
          
• Updated the pdftops filter to be based upon Xpdf
          2.02pl1 (STR #191)
          
• The scheduler did not reset the group list when
          running CGI and filter processes (STR #185)
          
• The scheduler no longer calls malloc and free from the
          signal handlers (STR #190)
          
• The USB backend now uses the manufacturer and model
          strings if the description string is not available
          (STR #174)
          
• The ppdOpen functions still supported the
          VariablePaperSize attribute, which was removed in v4.0
          of the PPD spec.  This caused problems with PPD files
          that relocated the PageSize option to a non-standard
          group (STR #158)
          
• The cups.list file referenced MAN1EXT, MAN3EXT, and
          MAN5EXT, but none of those were actually defined (STR
          #147)
          
• Chunked requests could cause a Denial of Service if
          the connection is terminated before the first byte of
          chunk data is sent/received (STR #143)
          
• Printers with special characters in their names were
          not accessible from the web interface (STR #120)
          
• The lpstat command now shows the correct interface
          script or PPD file, if any, for a print queue (STR #89)
          
• The lpstat command now shows the printer-state-message
          and printer-state-reasons attributes whenever they are
          not blank (STR #152)
          
• The French and German option-conflict.tmpl template
          files did not get installed (STR #148)
          
• The cups.list.in file did not work when compiling
          without shared libraries (STR #149)
          
• The DSOFLAGS included the LDFLAGS, which causes
          problems on at least HP-UX (STR #150)
          
• The fax printer support did not keep track of the fax
          capability bit (STR #144)
          
• The appleLangDefault() function could leak a small
          amount of memory (STR #145)
          
• The ppdOpen() functions now mirror all normal
          attributes to the attribute list; previously only
          certain unassigned attributes would be added (STR
          #139)
          
• The ppdEmitJCL() function wrote JCL commands to stdout
          instead of the passed file pointer (STR #142)
          
• The httpGets() function could, in certain states,
          block waiting for data (STR #132)
          
• The cupsEmitJCL() function not outputs an empty @PJL
          command after the PJL language escape to work around
          bugs in certain PJL implementations (STR #131)
          
• The cupsEmit*() functions didn't set the orientation
          value properly (STR #127)
          
• The cups.spec file didn't list the rc2.d init
          directory or the cupstestppd file (STR #134)
