CHANGES IN CUPS v1.0.5
- The HP-GL/2 filter did not correctly set the pen color
for pens other than #1.
- The scheduler would only accept 26 simultaneous jobs
under some OS releases (mkstemp() limitation.) It now
handles up to 2^32 simultaneous jobs.
- The PostScript filter loaded the printer's PPD file
- The PAM authentication code now uses pam_strerror() to
provide a textual error message in the error_log file.
- The scheduler now copies PPD and interface script
files instead of moving them; this fixes installations
with a separate requests directory.
- The PostScript RIP did not generate correct 6-color
- Several filters were marking PPD options twice when
they didn't need to.
- The scheduler did not save the printer or class state
after an accept-jobs or reject-jobs operation.
- The cupsGetDefault() function now ignores the PRINTER
environment variable if it is set to "lp".
- New ippErrorString() function to get textual error
- Better error reporting in the System V commands.
- The lpadmin and lpstat commands always tried to
connect to the default server.
- The text filter didn't load the charset files from the
- Wasn't sending a WWW-Authenticate: field to HTTP
clients when authentication was required.
- httpSeparate() didn't always set the default port
number for known methods.
- The HP-GL/2 filter now looks for "PSwidth,length"
instead of (the correct) "PSlength,width" as
documented by HP. It appears that many major CAD
applications are broken and this change allows the
auto-rotation to work with them.
- The IPP "printer-resolution" option was not being
- The charset files did not include the Microsoft
"standard" characters from 128 to 159 (unused by the
- The scheduler was chunking the Content-Type field from
CGI programs; this problem was most noticeable with
Microsoft Internet Explorer 5.
- By popular demand, the printers, jobs, and classes
CGIs no longer force a reload of the page every 10/30
- The scheduler incorrectly required that the IPP client
provide a document-format attribute for the
- Clients that sent bad IPP requests without the
required attributes-natural-language and
attributes-charset attributes would crash the
CHANGES IN CUPS v1.0.4
- Documentation updates.
- Jobs would get stuck in the queue and wouldn't print
until you enabled the queue.
- The lp and lpr commands now catch SIGHUP and SIGINTR.
- The lp and lpr commands now use sigaction or sigset
- CUPS library updates for WIN32/OS-2
CHANGES IN CUPS v1.0.3
- Documentation updates.
- The lpq man page was missing.
- The configure script was not properly detecting the
- The top-level makefile was calling "make" instead of
- PostScript filter fixes for number-up, OutputOrder,
- The imagetops filter didn't end the base-85 encoding
properly if the image data was not a multiple of 4
bytes in length.
- The imagetoraster filter didn't generate good banded
RGB or CMY data (was dividing the line width by 4
instead of 3...)
- The imagetoraster filter now records the bounding
box of the image on the page.
- The CUPS image library cache code wasn't working as
designed; images larger than the maximum RIP cache
would eventually thrash using the same cache tile.
- The CUPS image library TIFF loading code didn't
handle unknown resolution units properly; the fixed
code uses a default resolution of 128 PPI.
- cupsGetClasses() and cupsGetPrinters() did not free
existing strings if they ran out of memory.
- The scheduler logs incorrectly contained 3 digits for
the timezone offset instead of 4.
- The scheduler now does a lookup for the default user
and group ID; the previous hardcoded values caused
problems with the LPD backend.
- The cancel-job operation now allows any user in the
system group to cancel any job.
- The cancel-job operation stopped the print queue if
the job was being printed.
- Now only stop printers if the backend fails. If the
filter fails then the failure is noted in the
error_log and printing continues with the next file in
- Now log whether a filter fails because of a signal
or because it returned a non-zero exit status.
- The root user now always passes the system group test.
- Printers with an interface script and remote printers
and classes didn't have a printer-make-and-model
- Added logging of lost/timed-out remote printers.
- The HP-GL/2 filter was scaling the pen width twice.
- Updated the HP-GL/2 filter to use a single SP (Set
Pen) procedure. This makes the output smaller and is
more appropriate since the filter keeps track of the
pen states already.
- The scheduler didn't handle passwords with spaces.
- The IPP backend now does multiple copies and retries
if the destination server requires it (e.g. HP
- The disable command didn't implement the "-c" option
(cancel all jobs.)
- Changed the CMYK generation function for the image file
and PostScript RIPs.
- The lp command didn't support the "-h" option as
- The AppSocket, IPP, and LPD backends now retry on all
network errors. This should prevent stopped queues
caused by a printer being disconnected from the
network or powered off.
- The scheduler now restarts a job if the corresponding
printer is modified.
- The image RIPs now rotate the image if needed to fit
on the page.
CHANGES IN CUPS v1.0.2
- The HP-GL/2 filter didn't always scale the output
- The HP-GL/2 filter now supports changing the page size
automatically when the "fitplot" option is not used.
- The cancel-job operation was expecting a resource name
of the form "/job/#" instead of "/jobs/#"; this
prevented the cancel and lprm commands from working.
- The backends didn't log pages when files were printed
using the "-oraw" option.
- The authorization code did not work with the Slackware
long shadow password package because its crypt() can
- The chunking code didn't work for reading the response
of a POST request.
- cupsGetPPD() now does authentication as needed.
- The N-up code in the PostScript filter didn't work
with some printers (grestoreall would restore the
default blank page and device settings).
- The N-up code in the PostScript filter didn't scale
the pages to fit within the imageable area of the
- Wasn't doing an fchown() on the request files. This
caused problems when the default root account group
and CUPS group were not the same.
CHANGES IN CUPS v1.0.1
- Documentation updates.
- Fixed a bunch of possible buffer-overflow conditions.
- The scheduler now supports authentication using PAM.
- Updated the Italian message file.
- httpEncode64() didn't add an extra "=" if there was
only one byte in the last three-byte group.
- Now drop any trailing character set from the locale
string (e.g. "en_US.ISO_8859-1" becomes "en_US")
- Fixed "timezone" vs "tm_gmtoff" usage for BSD-based
- Updated IPP security so that "get" operations can be
done from any resource name; this allows the CGIs to
work with printer authentication enabled so long as
authentication isn't turned on for the whole "site".
- The IPP code didn't properly handle the "unsupported"
group; this caused problems with the HP JetDirect since
it doesn't seem to support the "copies" attribute.
- The HTTP chunking code was missing a CR LF pair at the
end of a 0-length chunk.
- The httpSeparate() function didn't handle embedded
usernames and passwords in the URI properly.
- Doing "lpadmin -p printer -E" didn't restart printing
if there were pending jobs.
- The cancel-job operation now requires either a
requesting-user-name attribute or an authenticated
- The add-printer code did not report errors if the
interface script or PPD file could not be renamed.
- Request files are now created without world read
- Added a cupsLastError() function to the CUPS API to
retrieve the IPP error code from the last request.
- Options are now case-insensitive.
- The lpq command now provides 10 characters for the
username instead of the original (Berkeley standard)
- The cancel command needed a local CUPS server to work
(or the appropriate ServerName in cupsd.conf)
- The cancel and lprm commands didn't report the IPP
error if the job could not be cancelled.
- The lp and lpr commands didn't intercept SIGTERM to
remove temporary files when printing from stdin.
- The lp and lpr commands didn't report the IPP error if
the job could not be printed.
