Common UNIX Printing System 1.1.20rc1

Subject: ANNOUNCEMENT: Common UNIX Printing System 1.1.20rc1

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)
