C News patch of 16-Jan-1990
Henry Spencer
henry at utzoo.uucp
Wed Jan 17 10:00:37 AEST 1990
This is the first of two coordinated patches; the second is set to appear
tomorrow. The big change, set up in the first and implemented in the
second, is that build has been revamped to use your previous answers as
the defaults for the next run. (Thanks to the magic :-( of context diffs,
and the large number of lines affected, the changes to build itself are
essentially the entire second patch.)
Other work is mostly further cleanout of the to-do list. Porting problems
with MAXLONG have been largely -- we hope -- eliminated by generating the
value in a more sophisticated way at run time. A new batch transmitter,
viauuxl, for multicast transmission (requires uux -l). Batchsplit modified
to reduce the time spent with the news system locked. Subst has been
fixed so it does not replace the target file if the new version is identical
to the old, and the main Makefile has been touched up to avoid doing a
subst run unnecessarily. Versions of queuelen for old and prehistoric
versions of uucp. An "addfeed" command for one common sysadmin chore.
Further expansion of notebook/problems to cover more porting troubles.
And the newsaux(8) manual page has been split, with the maintenance stuff
moving to newsmaint(8).
start of patch 16-Jan-1990

\fIUpact\fR is a distasteful kludge,

+ \fIUpact\fR forces the third field of the \fIactive\fR file to be at least
+ five digits, for backward compatibility, but otherwise just makes it as
+ large as necessary.
+ The group-creation operations always create it ten digits long.
+ The discrepancy is harmless, since unlike the second field, the third
+ field is never updated in place.

.PP
- .I Newshist
- prints the history line for each article identified by a \fImsgid\fR.
- .PP

(Some brain-damaged versions of \fIln\fR helpfully remove \fIlockname\fR
in that case, making them useless for locking.)
- .PP
- .I Newsdaily
- performs minor maintenance chores
- that typically should be done once a day for the news system:
- saving copies of log files and truncating them,
- reporting logged errors, checking for anomalies suggesting something
- is wrong, and cleaning out leftover files.
- \fINewsdaily\fR saves one generation of old \fIlog\fR files and three
- generations of old \fIerrlog\fR and \fIbatchlog\fR files.
- It reports problems to the named \fIguru\fRs
- (default: `\*m').
- .PP
- .I Newswatch
- looks for indications of news problems on a shorter time scale than those
- reported by \fInewsdaily\fR, notably strangely-persistent lock files that
- may indicate a news-system failure.
- It typically should be run a few times a day.
- .PP
- .I Newsboot
- should be run from \fI/etc/rc\fR or the system's equivalent on reboot.
- It cleans up files that the news system might have left lying about
- if the system crashed while news was being processed,
- notably old lock files.
- .PP
- .I Locknews
- locks the news system, starts up a shell for the user, and waits around to
- unlock the news system when that shell terminates.
- This simplifies manual maintenance.
- .PP
- .I Addgroup
- and
- .I delgroup
- respectively add a newsgroup (with a specified flags field for the
- \fIactive\fR file, normally `y' [see \fInews\fR(5)]) and delete a
- newsgroup manually, with proper locking.
- The effect is purely local; no control message (to propagate the
- change to other machines) is sent.
- .PP
- .I Adddirs
- sweeps through the \fIactive\fR file checking that directories exist for
- all newsgroups.
- (\fIRelaynews\fR
- will create directories as needed, but some
- user-interface software gets upset if a newsgroup exists but its directory
- does not.)
- This is mostly useful when adding groups in bulk, based on another site's
- \fIactive\fR file.

The need for \fIsizeof\fR and \fInewslock\fR is a botch.
- .PP
- \fILocknews\fR is a bit crude.
- .PP
- \fIDelgroup\fR does not remove files or directories from \*a, although it

.PP

--- 142,307 ----
telling \fIbuild\fR that you don't want to use the fast-stdio stuff is
always safe.
+ .SH
+ Readnews vs. System V
.PP
! The terminal handling in the Australian \fIreadnews\fR that we include
! is known not to work under a ``pure'' System V.
! There are stubs for System V code but it's never been implemented.
! Most current System V implementations from serious suppliers have enough
! BSD compatibility that this is not an issue.
! .SH
! Readnews Simplicity
! .PP
! Generally, the Australian \fIreadnews\fR
! is a bit on the simple and buggy side.
! There are various things wrong with it that we're not very interested
! in fixing\(emwe consider it useful primarily for naive users who just
! want to read system announcements, and recommend that sophisticated
! users use something else.
! One known interoperability issue is that it is fussier about the format
! of \fI.newsrc\fR files than fancier readers.
! .PP
! Problems will arise if the news directories are in non-standard places,
! because \fIreadnews\fR is not well integrated into our configuration
! machinery; we want to fix this someday.
! .SH
! void
! .PP
! Old compilers that don't understand the \fIvoid\fR type will choke on
! much of our code.
! There is a commented-out ``#define\ void\ int'' in \fInews.h\fR that
! cures most cases of this if you uncomment it.
! (We have a report that you might need to add ``\-Dvoid=int'' to the
! Makefile in \fIlibv7\fR if you're using that library.)
! C News does not rely on the ANSI C ``void\ *'' type as far as we know.
! .SH
! Read/write Modes in fopen
! .PP
! Unix V7 documented only ``r'', ``w'', and ``a'' as suitable mode arguments
! to \fIfopen\fR.
! It actually implemented the read/write modes, ``r+'', ``w+'', and ``a+'',
! as well, and C News relies on them.
! Unix reimplementations based on old documentation may have trouble here;
! we know that at least the older versions of Minix really don't implement
! these modes.
! .SH
! MAXLONG
! .PP
! The \fIrelay/cpu.h\fR file formerly defined a constant \fIMAXLONG\fR
! which is the biggest positive value of a \fIlong\fR.
! The definition was clever but failed on some odd systems (Unisys?).
! Current versions of C News
! generate the value dynamically in a less fallible way,
! and check the value for plausibility.
! (This is encountered when \fIrelaynews\fR is asked to
! process a single article, not a batch.
! This happens primarily when an article is posted locally, with \fIinews\fR.)
! .SH
! df Output Format
! .PP
! The \fIspacefor\fR utility needs to understand the output format of \fIdf\fR.
! There are numerous variations on \fIdf\fR.
! \fIBuild\fR and the relevant makefiles know about the more common ones,
! but customization may be necessary.
! \fISpacefor\fR is commented well enough that it should be possible to
! figure out the necessary changes; usually the initializations of \fInr\fR
! and \fInf\fR are all that need changing.
! If there are colons (:) in your \fIdf\fR's output format, you should
! probably start from the ``sysv'' \fIspacefor\fR, which attempts to
! preprocess the output to get rid of System V garbage;
! otherwise the ``bsd'' one is a reasonable starting point.
! .PP
! One constant nuisance is \fIdf\fRs that are too stupid to take a directory
! name as an argument.
! The long-term solution to this is to edit a suitable variant of \fIspacefor\fR
! to know about the proper arguments.
! A short-term solution is to use the ``null'' variant, sacrificing space
! checking for the sake of getting something working.
! .SH
! Floating Point
! .PP
! The only place in C News where floating point is used, as far as we know,
! is in the calculation of expiry dates in \fIexpire\fR.
! This is not a performance bottleneck, so slow floating-point arithmetic
! is not a problem.
! Complete absence of floating point would require minor modifications to
! \fIexpire\fR.
! .SH
! 386 Optimizer vs. dbz
! .PP
! We have a reliable report that the System V 386 optimizer (invoked when
! \fIcc\fR is given the \fB\-O\fR option) miscompiles the \fIdbz\fR package
! badly enough to cripple it, without producing any error messages.
! The only fix is to compile \fIdbz\fR without \fB\-O\fR.
! .SH
! HP Spectrum Optimizer vs. nnfree
! .PP
! We have a reliable report that
! the HP Spectrum C compiler has an optimiser bug that makes it throw up
! (with a
! ``cc: Internal error 3279: Please contact your local HP representative''
! message)
! on the \fInnfree\fR macro in \fIh/news.h\fR.
! The following revised version of
! the macro reportedly avoids
! the problem.
! .DS
! #define nnafree(mempp) do { if (*(mempp) != 0) { free((char *)*(mempp)); \e
! *(mempp) = 0; }} while (0)
! .DE
! .SH
! ANSI C
! .PP
! Although we made an effort to be ANSI-C compatible,
! lack of access to a real ANSI C compiler limits our ability to do this.
! A secondary problem is that it's really very difficult to get code that
! is 100% acceptable to both ANSI C compilers and older compilers.
! Some issues inevitably got resolved in favor of current compilers,
! and may cause complaints from ANSI C compilers.
! .SH
! GNU C
! .PP
! If compiling with the GNU compiler, you will need the
! \fB\-traditional\fR flag.
! Beware, also, that if you are using your system's \fIdbm\fR library,
! it contains functions that return structure values, and the GNU conventions
! for handling such values are incompatible with the ones in many AT&T-derived
! compilers.
! The
! \fB\-fpcc-struct-return\fR option cures this.
! .SH
! Eccentric Awks
! .PP
! A number of problems can arise if your \fIawk\fR has bugs, since the shell
! files rely on \fIawk\fR fairly extensively.
! For example, \fIawk\fR is a prime suspect if \fIspacefor\fR doesn't work.
! We've fixed the worst trouble spots, but would appreciate detailed information
! on any more.
! .SH
! Systems Without Hard Links
! .PP
! Some vaguely Unixoid systems have trouble implementing real (``hard'') links.
! Examples are VMS in general and Eunice in particular.
! There are some hooks for dealing with this, but it's not trivial.
! .PP
! \fIRelaynews\fR will try to make symbolic links if real ones fail.
! There is one exception:
! if \fIrelaynews\fR cannot buffer up enough of the article in memory to
! find the `Newsgroups:' line, it will drop the article into a temporary
! file and will rely on being able to move that to the first of the
! `real' locations by manipulating links.
! This should essentially never happen except on 16-bit machines,
! and should be rare even on them.
! .PP
! \fIExpire\fR has a \fB\-l\fR option which
! tells it to consider the first filename of an article its `leader',
! not expiring the article under that name until it has expired under
! all others.
! This has not been tested much recently.
! .PP
! The locking system (both C routines and the \fInewslock\fR program)
! will need revision in some system-dependent way to avoid use of links.
! .PP
! There is one minor use of links in installation (\fIinews\fR is found
! in two places, and the Makefile attempts a link before doing a copy),
! and substantially more in the regression tests.

+ .SH DESCRIPTION
+ These programs are utilities useful in maintaining a C News
+ system and diagnosing problems in it.
+ .PP
+ .I Newshist
+ prints the history line for each article identified by a \fImsgid\fR.
+ .PP
+ .I Newsdaily
+ performs minor maintenance chores
+ that typically should be done once a day for the news system:
+ saving copies of log files and truncating them,
+ reporting logged errors, checking for anomalies suggesting something
+ is wrong, and cleaning out leftover files.
+ \fINewsdaily\fR saves one generation of old \fIlog\fR files and three
+ generations of old \fIerrlog\fR and \fIbatchlog\fR files.
+ It reports problems to the named \fIguru\fRs
+ (default: `\*m').
+ .PP
+ .I Newswatch
+ looks for indications of news problems on a shorter time scale than those
+ reported by \fInewsdaily\fR, notably strangely-persistent lock files that
+ may indicate a news-system failure.
+ It typically should be run a few times a day.
+ .PP
+ .I Newsboot
+ should be run from \fI/etc/rc\fR or the system's equivalent on reboot.
+ It cleans up files that the news system might have left lying about
+ if the system crashed while news was being processed,
+ notably old lock files.
+ .PP
+ .I Locknews
+ locks the news system, starts up a shell for the user, and waits around to
+ unlock the news system when that shell terminates.
+ This simplifies manual maintenance.
+ .PP
+ .I Addgroup
+ and
+ .I delgroup
+ respectively add a newsgroup (with a specified flags field for the
+ \fIactive\fR file, normally `y' [see \fInews\fR(5)]) and delete a
+ newsgroup manually, with proper locking.
+ The effect is purely local; no control message (to propagate the
+ change to other machines) is sent.
+ .PP
+ .I Adddirs
+ sweeps through the \fIactive\fR file checking that directories exist for
+ all newsgroups.
+ (\fIRelaynews\fR
+ will create directories as needed, but some
+ user-interface software gets upset if a newsgroup exists but its directory
+ does not.)
+ This is mostly useful when adding groups in bulk, based on another site's
+ \fIactive\fR file.
+ .PP
+ .I Addfeed
+ adds a line to the \fIsys\fR file specifying that the \fIsite\fR should
+ be fed the \fIgroups\fR,
+ and creates a suitable outbound-batching directory.
+ If the
+ .B \-L
+ option is given, the \fBL\fR flag is included to restrict the feed to
+ locally-generated articles only.
+ If \fIgroups\fR does not include a distribution list (separated from the
+ newsgroups by a `/'), the default distribution list `/all' is appended.
+ If \fIgroups\fR is of the form \fB=\fIname\fR,
+ this specifies the same groups as those fed to site `\fIname\fR',
+ with the exception that `to.\fIname\fR' is rewritten to `to.\fIsite\fR'.
+ .SH FILES
+ .ta 6c
+ .nf
+ \*c/history history file
+ \*c/history.pag \fIdbm\fR database for history file
+ \*c/history.dir \fIdbm\fR database for history file
+ \*c/log current news log
+ \*c/log.o previous news log
+ \*c/errlog current news-error log
+ \*c/errlog.o* old news-error logs
+ \*c/batchlog current news-batcher log
+ \*c/batchlog.o* old news-batcher logs
+ \*a/in.coming input-spooling area
+ \*a/out.going output-batching area
+ \*c/watchtime last time \fInewswatch\fR was run
+ \*c/active list of current newsgroups
+ \*c/active.old backup copy created by \fIaddgroup\fR and \fIdelgroup\fR
+ .SH SEE ALSO
+ df(1), uucp(1), ls(1), ctime(3), getdate(3), hostname(1),
+ grep(1), news(5), expire(8), newsbatch(8), rnews(8), newsaux(8)
+ .SH DIAGNOSTICS
+ .I Locknews
+ complains and exits if it is unable to lock the news system; this is
+ typically a matter of either inadequate permissions or news activity
+ already in progress.
+ .PP
+ .I Addfeed
+ looks for a \fB/default/\fR line
+ or a line for \fIsite\fR in
+ the \fIbatchparms\fR file, and if
+ none is found, warns the user to create one.
+ .SH HISTORY
+ Written at U of Toronto by Henry Spencer and Geoff Collyer.
+ .SH BUGS
+ \fILocknews\fR is a bit crude.
+ .PP
+ \fIDelgroup\fR does not remove files or directories from \*a, although it
+ prints a reminder to do so.
+ .PP
+ The \fB=\fIname\fR form of \fIaddfeed\fR
+ cannot cope with continued \fIsys\fR lines.
+ .PP
+ \fIAddfeed\fR assumes that attention to the \fIbatchparms\fR file suffices
+ to get batching going for a new feed, which is naive if you are running
+ \fIsendbatches\fR selectively, i.e. with arguments.
+ .PP
+ Various nuisances can result if the maintenance utilities are run as
+ \fIroot\fR rather than as the owner of the news database.
+ It's difficult to defend against this.
