XSee our paper in the winter 1987 Usenix for some details of how. X XC news does not include an all-singing-all-dancing news reader. We think XLarry Wall's rn is the reader of choice. There are others. We have no Xdesire to write one ourselves. X XWe have included the Australian readnews (with permission) as a simple Xnews reader, for those who wish to dispense with B news completely. XNote that we have changed it a bit and bugs should be assumed to be our Xfault not Michael Rourke's. X XFor those who have run one of our ancient pre-beta versions, many things Xhave changed, and in particular the four-field history file format is gone. X XSpeaking of file formats... X XThe active file format is the 4-field one that B news introduced midway Xthrough 2.10, unchanged. X XThe history file format is like B with one exception: the second field, Xwhich few programs ever look at, now consists of two subfields separated Xby a tilde (~). The first is the arrival date as a decimal number, the Xsecond is the expiry date (if any) as a human-readable date (as emitted by Xrnews) or a decimal number (after expire has gotten its hands on it once). XExpire is tolerant of human-readable dates in both those places, but other Xthings may not be. The best way to get the history file into the new Xformat is to rebuild it completely (this is RELATIVELY quick). X XThe sys file format is like a late-model B news with two extensions. First, Xthe second field (groups and distributions) may optionally be split into Xtwo subfields (newsgroups and distributions, respectively) with a slash. XThis permits solutions to various tricky problems that can arise in odd Xsituations if it is impossible to tell what's a newsgroup name and what's Xa distribution. Second, there is a new flag in the third field: f is like XF except that its output has the size information that the C batcher Xwants for accurate limiting of batch size. (Incidentally, note a limitation, Xone that will be fixed in the definitive release: with both f and F, having Xthe same filename in more than one sys-file line is, uh, a bad idea. The Xbatcher is flexible enough to get around most needs for this.) X XThe way the news articles themselves are stored is totally unchanged; we Xhave been unable to think of any changes that are worth the trouble. X XFinally, there is a new control file, conventionally named X/usr/lib/news/explist, which is expire's control file (see the expire Xmanual page) (pre-alpha sites, note that the format has changed). X XFile organization: the one change is that programs are now kept mostly in X/usr/lib/newsbin, with /usr/lib/news reserved for control files etc. Most X(by intent all) of the programs understand four key environment variables: XNEWSARTS specifies location of articles (default /usr/spool/news), NEWSCTL Xspecifies location of control files (default /usr/lib/news), NEWSBIN gives Xlocation of programs (default /usr/lib/newsbin), and NEWSUMASK gives the Xumask to be used in creating files (default 002). The environment variables Xoverride the defaults for testing and for operation in funny situations. XNote that one or two things (e.g. relaynews), as distributed, will insist Xon renouncing setuid privileges if invoked with these overrides. X XC news is divided into various subsystems, each occupying a directory Xof its own. X XTwo directories -- include and libcnews -- are support stuff (respectively Xinclude files and library functions) used by most of the subsystems. X XThe libc directory contains stuff that is in our C libraries but might not Xbe in yours. X XThe input spooler, which accepts incoming news batches and spools them Xup for later processing, is in directory input. Be warned: it does do one Xessential function other than spooling -- it strips the stupid "#! cunbatch" Xheader off 2.11-style batches. It includes the "rnews" program that goes Xin /bin (or /usr/bin, or wherever); "rnews" and "cunbatch" are identical Xin C news. X XThe output batcher is in directory batch. It will work with B news as well, Xalthough not as well (it really wants to be told the size of an article as Xwell as its name). X XExpire and its friends, including history rebuilding and active-file updating X(neither of which are done by expire itself in C news) are in directory Xexpire. X Xgngp contains a grep-like program which matches newsgroups, used in inews Xamong other things. X Xtime contains a couple of small programs occasionally useful in maintaining Xthe history file with its numeric dates -- ctime converts numeric to human Xand getdate goes the other way. X Xnewshist contains a maintenance program which accepts a news message-ID Xand prints the history line for that article. X Xmail contains various bits of software for shipping news via mail, both Xcleaner and faster than uurec et al. X Xlib.proto is a sort of prototype /usr/lib/news containing some useful things X(notably newsboot, which should be run from /etc/rc on reboot) and some old Xunnecessary trash (probably). newsbin.proto is similar for /usr/lib/newsbin. X Xrna is the Australian readnews, plus other odds and ends of their software Xthat we haven't sorted through yet. X XAnd rnews is the Augean Stables themselves (read RFC850 if you don't believe Xus): the news-relaying software, containing most of the work and most of Xthe speedup. Various auxiliaries, sped-up versions of libraries, and other Xthings proliferate underneath this directory. Of note is setnewsids, a little Xsetuid-root (gasp!) program needed on systems which do not permit the Xsetuid(geteuid()) operation, to make relaynews run with the right ownerships. XNote, by the way, that the only program now named "rnews" is the one in Xthe input subsystem, although programs with various related names live under Xthe rnews directory. This was a late change, removing much previous Xconfusion but perhaps creating some of its own.

XIt should be run periodically, under userid \fInews\fR, Xby \fIcron\fR(8) or similar means. XIt prepares and sends batches of news, Xsubject to restrictions on available space and length of outbound queues. X.PP X\fISendbatches\fR and all its auxiliaries recognize the standard Xenvironment variables \fB$\&NEWSARTS\fR, X\fB$\&NEWSCTL\fR, \fB$\&NEWSBIN\fR, and \fB$NEWSUMASK\fR Xwhich indicate, respectively, non-default locations Xfor news articles, news control files, and news programs, Xand a non-default \fIumask\fR (see \fIumask\fR(2)) for file creation X(the default \fIumask\fR is 002). X.PP XEach site that can have batches sent to it needs a \fBb.\fIsite\fR directory Xunder \fI$\&NEWSCTL/batch\fR. XBy default \fIsendbatches\fR considers preparation of batches for all Xsites that have such a directory, in order as given Xby the \fIsites\fR file (see below). XIf \fIsendbatches\fR Xis invoked with \fInames\fR of specific sites, it considers only those Xsites as candidates for batching, in the order given. XIf it is invoked with a X.B \-c Xoption, the \fInames\fR are classes of sites, which are considered Xin the order given, Xwith order within each class set by order in the \fIsites\fR file. X.PP XIf there is a \fI$\&NEWSCTL/batch/sites\fR file, it controls ordering of sites Xand assignment of sites into classes. XEach line consists of one or more white-space-separated fields, Xthe first being a site name, and the rest X(if any) Xbeing names of classes to which Xthat site belongs. XBlank lines and lines beginning with `#' are ignored. XThe order of lines determines the default order of \fIsendbatches\fR Xprocessing, with any unmentioned sites going last. XIf there is no \fIsites\fR file, classes cannot be used and the default Xsite ordering is alphabetical. X.PP XTo use the batcher, names of files to be sent to a specific site should Xbe appended to a \fItogo\fR file in its \fBb.\fIsite\fR directory. XThe batcher expects the lines in \fItogo\fR to have two fields, a filename X(as a full pathname) of an article and its size in bytes. XA missing size field is arbitrarily assumed to be a default average. X.PP X\fISendbatches\fR uses a number of auxiliary programs to do the real work. XThe search path it uses to find them includes, in order, Xthe \fBb.\fIsite\fR directory for the site in question, X\fI$\&NEWSCTL/batch\fR, and \fI$\&NEWSBIN/batch\fR. XThis permits per-site and per-news-database overrides of the default Xbehaviors. X\fISendbatches\fR provides all these programs with an environment Xvariable \fB$NEWSSITE\fR, containing the name of the site that batches Xare being prepared for, in case this is useful in customization. X.PP XFor each site being considered for batches, \fIsendbatches\fR first Xdetermines whether there are in fact any articles to be batched. XAssuming there are, \fIsendbatches\fR then invokes \fIqueuelen\fR Xto find out how many batches are in the outbound queue for Xthe site, \fIqueuemax\fR to find out how long queues are allowed to be, X\fIbatchsize\fR to determine how big batches should be (in bytes), Xand \fIroomfor\fR Xto determine how many batches of that size will fit without depleting the Xavailable spool space too much. X\fISendbatches\fR limits the number of batches prepared to the minimum of Xthe limits implied by queue lengths and available space. X.PP X\fISendbatches\fR uses \fIbatchprep\fR Xas necessary Xto slice chunks out of the \fItogo\fR Xfile, each chunk containing the X\fItogo\fR lines for a batch limited to the specified size. XException: a single article bigger than the specified size will still go out Xas one batch. X.PP XEach chunk is then processed through \fIbatchmake\fR, which assembles the Xarticles into a batch, \fIbatchmunch\fR, which performs auxiliary processing X(e.g. data compression), and \fIbatchxmit\fR, Xwhich sends the batch on its way (e.g. enqueues it for transmission). XIf \fIbatchmake\fR is invoked with a \fB\-d\fR option, it \fIchdir\fRs to Xthe \fIdirectory\fR first, and strips it off the beginning of any article Xfilename that starts with it. XSince most articles will come from \fI$\&NEWSARTS\fR, specifying X\fB\-d\ $\&NEWSARTS\fR to \fIbatchmake\fR will speed it up noticeably. X.PP X\fISendbatches\fR logs some information about sites with backlogs in X\fI$\&NEWSCTL/batchlog\fR, keeping the previous \fIbatchlog\fR in X\fIbatchlog.o\fR and the one before that in \fIbatchlog.oo\fR. XThis is intended to help detection and diagnosis of flow problems.

X.SH BUGS X\fIBatchprep\fR does not count the `#!\ rnews\ \fInnnn\fR' headers inside Xbatches when computing batch lengths. X.PP X\fIBatchprep\fR arguably should be smarter about determining file sizes Xin the absence of counts in the \fItogo\fR file.

XNormally X.I postnews Xis used interactively, in which case no arguments are required, Xand X.I postnews Xwill prompt the user for the subject, newsgroup and distribution Xfields. XIf any other fields are required they must be specified on the command Xline. XThe article text may then be entered, and may be terminated by a `.' or EOT. XLike X.IR mail (1), Xcommands are available while entering an article, to escape to an Xeditor, interpolate the current article or run a shell command. X.P XThe second two forms of the X.B postnews Xcommand are for news administration use only. X.I Postnews Xis often called by X.IR readnews (1) Xto post follow-up articles, and post new articles; Xmany flag arguments are provided for this purpose. X.P XOptional flags are: X.TP X.B -h Xis used when input is redirected from a file containing an article. XIt specifies that headers are present at the beginning of the article, Xand that these headers should be included with the article header instead Xof as text. XOnly headers the user may set are permitted. X.TP X\fB-s \fIsubject\fR Xspecifies the subject of the article. XIf it is not specified in this way it must be specified interactively. XThis must be carefully chosen to be brief yet descriptive. X.TP X\fB-n \fInewsgroups\fR Xspecifies a comma separated list of newsgroups to which the article Xwill be posted. XThe default is X.BR general . X.TP X\fB-d \fIdistribution\fR Xusually not specified, is the same format as a newsgroup, Xand is used to restrict the article's distribution to those Xhosts which subscribe to the group(s) specified. X.TP X\fB-e \fIexpiredate\fR .. Xspecifies a date for the article to expire (instead of the usual default). XThe format of the date arguments are as follows: X.RS 5 X.TP 14 X.IR day : X( X.I dayofweek X[ X.B week X] ) | X.BR 1 .. 31 X.RS 2 X.TP 14 X.IR dayofweek : X.B sunday X| ... | X.B saturday X| X.B tomorrow X| X.B today X.RE X.TP X.IR month : X.B january X| ... | X.B december X.TP X.IR year : X.BR 1970 .. 2038 X.RE X.P X.RS 5 XThe arguments X.I day X, X.I month Xand X.I year Xare order-independent, Xand words may be shortened to a non-ambiguous abbreviation.

X.P X.RE X.TP X\fB-r \fIreferences\fR Xusually used by X.IR readnews (1) Xwhen posting a followup article. X.I references Xcontain the message-id of the article being followed up. X.TP X\fB-i \fIinterpfile\fR Xusually used by X.IR readnews (1) Xwhen posting a followup article. X.I interpfile Xis the file available to the `.i' command when entering an Xarticle interactively. X.TP X\fB-c \fIcontrol_command\fR Xspecifies special control commands. XCommands are X\fR`\fBnewgroup \fIgroupname\fR' Xto create a new newsgroup (news admin only) Xand X\fR`\fBcancel \fImessageid\fR' Xto cancel a message (sender or news admin only). XNewsgroups and distribution may be specified to Xlimit the scope of the control command. X.TP X.B -p Xindicates the article on standard input has come from Xanother host (and contains headers etc.) - news admin only. X.P XWhen entering an article interactively, Xa X.RB \&' . ' Xor EOT Xby itself on a line terminates entering and posts the article. XOther commands are available: X.TP X\&\fB.e\fR XEdit the article collected so far (see X.IR ed (1)). XAfter editing further lines may be appended to the article. X.TP X\&\fB.i\fR XInterpolate Xthe file specified by the X.B -i Xflag Xonto the end of the message. The interpolated item Xis indented by four spaces. X.TP X\&\fB.!\fIcmd\fR or \fB!\fIcmd\fR XShell escape. X.IR Cmd Xis executed. X.TP X.B DEL XCauses posting to be aborted, and the article entered so far Xis saved in X.BR $HOME/dead.article . X.P XWhen posting an article, the environment is checked for information Xabout the sender. XIf X.B NAME Xis found, Xits value is used for the full name, rather than the system value X(found in X.BR /etc/passwd ). XIf X.B ORGANIZATION Xis found, Xthe value overrides the system default organization. XAn alternative editor (for the X.B .e Xcommand) may be used by setting X.B EDITOR Xin the environment.
