| 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 |
| twice. |
| - 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 |
| output. |
| - 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 |
| messages. |
| - 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 |
| correct location. |
| - 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 |
| translated. |
| - The charset files did not include the Microsoft |
| "standard" characters from 128 to 159 (unused by the |
| ISO-8859-x charsets) |
| - 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 |
| seconds. |
| - The scheduler incorrectly required that the IPP client |
| provide a document-format attribute for the |
| validate-job operation. |
| - Clients that sent bad IPP requests without the |
| required attributes-natural-language and |
| attributes-charset attributes would crash the |
| scheduler. |
| |
| |
| 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 |
| when available. |
| - 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 |
| image libraries. |
| - The top-level makefile was calling "make" instead of |
| "$(MAKE)". |
| - PostScript filter fixes for number-up, OutputOrder, |
| and %Trailer. |
| - 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 |
| the queue. |
| - 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 |
| attribute. |
| - 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 |
| JetDirect.) |
| - 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 |
| documented. |
| - 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 |
| correctly. |
| - 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 |
| return NULL. |
| - 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 |
| page. |
| - 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 |
| operating systems. |
| - 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 |
| username. |
| - 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 |
| permissions. |
| - 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) |
| 7. |
| - 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. |
