this makes it possible, for example, to link against a pre-built DSO <LI><B>configure</B> now automatically purges any <B>config.cache</B> file if configuration parameters are specified on the command line or if a <B>config.site</B> or <B>config.local</B> file has been modified since <B>config.cache</B> was last written <LI>several fatal errors during configuration now elicit more verbose information from <B>configure</B> <LI><B>configure</B> now aborts if the <TT>strftime</TT> or <TT>socket</TT> functions are not located in the expected places <LI>a bug was fixed where <B>configure</B> would inject diagnostic information in the <B>port.h</B> file if memory mapped files were not found to be supported in the expected way <LI>the <TT>ZLIB</TT>, <TT>LIBZ</TT> and <TT>ZLIBINC</TT> configuration parameters were added to specify the location of the zlib software <LI>the <TT>REGEX</TT>, <TT>LIBREGEX</TT> and <TT>REGEXINC</TT> configuration parameters were added to specify the location of the regex software <LI>several extraneous references to the math library (<TT>-lm</TT>) were removed from Makefiles </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="faxq"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQ:</B></A> <UL> <LI>a bug was fixed that caused active jobs to be terminated when they were to be suspended <LI>aborting outbound jobs is now handled better <LI><B>faxq</B> now waits for sub-processes to terminate when a job is to be suspended or aborted; this corrects a race condition that caused clients to sometimes get incorrect results <LI>a bug was fixed where a reference to a job might be left on the active queue when faxq could not fork to startup a sub-process <LI><B>faxq</B> now honors a job's state when initially scanning the job queue at startup; this means, in particular, that suspended jobs are no longer automatically submitted <LI>the scheduling algorithm was reorganized so that jobs are processed ``more aggressively''; this causes jobs to be dispatched in an order that more closely parallels the order in which they are submitted </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="faxsend"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXSEND:</B></A> <UL> <LI>the total number of pages to send--as seen by the client--is now properly maintained <LI>a bug was fixed that caused certain abort requests to be ignored </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="pagesend"><B><FONT SIZE=+3>C</FONT>HANGES TO PAGESEND:</B></A> <UL> <LI>a bug was fixed that caused certain abort requests to be ignored <LI>a bug was fixed that caused non-default parity settings to not be handled properly </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="faxgetty"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXGETTY:</B></A> <UL> <LI>a portability problem that caused core dumps on 68K systems was fixed </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="faxqclean"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQCLEAN:</B></A> <UL> <LI>malformed job files are now removed instead of being ignored </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="hfaxd"><B><FONT SIZE=+3>C</FONT>HANGES TO HFAXD:</B></A> <UL> <LI><TT>JPARM DOCUMENT</TT> now returns the set of document files for a job <LI><TT>JPARM COVER</TT> now returns any cover page document for a job <LI><TT>JPARM POLL</TT> now returns any polling requests for a job <LI><TT>JPARM</TT> now includeds document and polling information in the status information it returns <LI>the <TT>%P</TT> and <TT>%y</TT> job status format escapes now correctly return the total number of pages to be sent for a job <LI>the SNPP support now correctly resets state after each <TT>PAGE</TT> request (per the spec) <LI>the SNPP <TT>SUBJ</TT> command now properly parses multi-token arguments <LI><TT>JPARM COMMID</TT> now returns the last communications identifier for a job <LI><TT>JPARM</TT> requests now work correctly when a job's state is updated by an unrelated thread of control <LI>the setting of many job parameters that have side effects is now handled properly; in particular this fixes a problem where setting a job's scheduling priority had no effect <LI>a bug was fixed in the <TT>%h</TT> job status format escape <LI>a <TT>%W</TT> job status format escape was added for printing a job's communication identifier <LI>a <TT>JINTR</TT> command was added that acts just like <TT>JSUSP</TT> except that an active job is aborted before it is suspended <LI>a bug was fixed that caused <TT>STOR</TT> requests that created a new file to fail <LI>a bug was fixed the permited unprivileged users to create files in private directories <LI>a portability problem was fixed for DEC Alpha systems <LI><TT>RETP</TT> is a new request that returns a single page from a TIFF document file; it can be used together with the <TT>REST</TT> request to selectively retrieve pages from a file <LI>a bug was fixed in the ZIP-compressed retrieval of files </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="sendfax"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDFAX:</B></A> <UL> <LI>the <TT>CoverCmd</TT> configuration parameter now specifies the absolute pathname for the program to use in generating cover pages <LI>strings passed as arguments to the <TT>CoverCmd</TT> program are no longer interpreted by the shell <LI>jobs are not submitted if a cover page cannot be created (jobs used to be submitted without a cover page) <LI>a bug was fixed that caused certain configuration parameters to be ignored <LI>the argument sent for the <TT>USETAGLINE</TT> job parameter is now properly typed as boolean </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="sendpage"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDPAGE:</B></A> <UL> <LI>the <TT>-s</TT> option is now correctly recognized <LI>a bug was fixed that caused reading messages from files to fail <LI>the <TT>SNPPSERVER</TT> environment variable is now correctly honored </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="faxmail"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXMAIL:</B></A> <UL> <LI>support was added to parse and specially format MIME-encoded messages <LI>support was added to directly deliver facsimile </UL> <P><HR WIDTH=65% ALIGN=right> <A NAME="misc"><B><FONT SIZE=+3>C</FONT>HANGES IN MISCELLANEOUS STUFF:</B></A> <UL> <LI><B>faxalter</B> now correctly handles ``<TT>-a now</TT>'' <LI><B>faxcover</B> now properly escapes backslash characters in emitted PostScript strings <LI>the <B>tiff2fax</B> script now uses symbolic links instead of hard links when a processing request requires no work; this fixes a problem where document files were being created with multiple links to them, causing <B>faxqclean</B> to not remove the files even though they were unreferenced <LI>a bug in <TT>killall</TT> emulation function was fixed in the <B>hylafax</B> system startup script <LI>the ``at syntax'' support now properly converts times of the form ``120 minutes'' <LI>boolean values in configuration files can now be specified as ``true'' and ``false'' <LI>the <B>ps2fax</B> symbolic link that is installed for the default PostScript RIP now references Ghostscript and is only installed if no file exists <LI>the text to PostScript conversion support was extended and a bug was fixed in the handling of lines with trailing white space <LI>client support for retrieving files was extended to support restarting a previous retrieval request <LI>an apparent problem in the socket support in SINIX MIPS 5.42 was worked around </UL> <!--FOOTER--> <A HREF="toc.html"><IMG SRC="icons/back.gif"></A> HylaFAX table of contents.<BR> <HR> <ADDRESS> <A HREF="sam.html">Sam Leffler</A> / <A HREF="mailto:sam@engr.sgi.com">sam@engr.sgi.com</A> Last updated $Date: 1998/10/12 20:47:51 $. </ADDRESS> </BODY> </HTML>
