Sun Dec 9 2001 Jim Hague <jim.hague@acm.org>

* src/util.c: Improve (correct) error detection when updating
  timestamp file.
* src/content.h, src/content.c: Return Boolean success/fail from
  Cont_write. Also ensure cont.first isn't polluted in the event
  of a failed update.
* src/client.c,src/control.c,src/fetch.c,src/noffle.c,src/post.c,
  src/pseudo.c,
* src/server.c: If groupinfo.lastupdate is unreadable or corrupt,
  spot this and report it and give an explicit error when processing
  NNTP NEWGROUPS command.

Sun Dec 9 2001 Jim Hague <jim.hague@acm.org>

* src/post.c: Always replace message ID in posted message if existing
  message ID fails Prt_isValidMsgId.
* noffle.conf.example,docs/noffle.conf.5,src/configfile.c: Change
  replace-messageid default from 'yes' to 'no'. These days bad message
  IDs from newsreaders shouldn't happen (or should be more easily fixable
  from the newsreader config), and replacing message IDs causes havoc if
  you're gatewaying mailing lists or similar.

Sun Dec 2 2001 Mirko Liß <mirko.liss@web.de>

* src/protocol.c: Use pid and count to generate MsgIDs, not random number.

Thu Nov 29 2001 Jim Hague <jim.hague@acm.org>

* src/content.c: Remove spurious temporary files and add a closedir()
  to terminate opendir()/readdir() sequence properly.
* Updated NEWS ready for 1.1.1.	
	
Thu Nov 22 2001 Jim Hague <jim.hague@acm.org>

* Makefile.in,aclocal.m4,config.h.in,configure,configure.in
  docs/Makefile.in,src/Makefile.in: Regularise format of Noffle
  default parameters in configure.in and regenerate.
* src/content.c,src/noffle.c: Correct bugfix in Conf_write().
  Remove temporary file expiry, but skip temp files in
  Cont_nextGrp().
	
Thu Nov 22 2001 Mirko Liß <mirko.liss@web.de>

* src/noffle.c: expireContents() expires overview temporary files.
* src/content.c: minor bugfix in Conf_write()
* docs/noffle.conf.5,src/configfile.c,src/filter.[ch]:
  Added filter post-status=mod|yes|no. Only the current group
  will be checked.
* src/client.c: Bugfix at processGrps(). Local groups are now always
  preferential. They won't change to an upstream server.

Wed Nov 14 2001 Mirko Liß <mirko.liss@web.de>

* src/noffle.c,docs/noffle.1: added optional pattern to select previously
  configured upstream server with 'noffle --fetch' and 'noffle --query'.

Tue Nov  6 2001 Jim Hague <jim.hague@acm.org>

* TODO: Update the TODO list.
* src/util.c: When updating timestamp files, write new stamp to temp file
  and rename, so failure with e.g. full disc doesn't leave an empty stamp
  file.
	
Sun Nov 11 2001 Mirko Liß <mirko.liss@web.de>

* src.util.c: Minor fix at Utl_parseNewsDate(); fixed SIGSEGV at
  Utl_getHeaderLn(). Header size limit still much too low.
* docs/testing.txt: How to set up a testbench for noffle. Useless
  for most developers, but useful for beginners.

Thu Nov  8 2001 Mirko Liß <mirko.liss@web.de>

* Makefile.am,Makefile.in: Minor fix I haven't previously included.
  The new --with-configfile option depends on it.
* docs/NOTES: Minor enhancement to slrn-script. Now it marks incomplete
  articles as unread.

Tue Nov  6 2001 Jim Hague <jim.hague@acm.org>

* packages/redhat/noffle.spec: Update to version to 1.1-1 and fix up some
  items causing RPM3 vs RPM4 problems.
* configure,configure.in: Bump version to 1.1.1-unstable-develop, and add
  --with-spooldir and --with-configfile options (idea due to Mirko Liss).
	
Wed Oct 31 2001 Jim Hague <jim.hague@acm.org>

* AUTHORS,INSTALL,NEWS,README,TODO,docs/NOTES,src/client.c,src/protocol.c,
  src/protocol.h,src/server.c: Merge with latest 1.0 branch. I do not
  intend to do any further merges from the 1.0 branch; future changes to
  1.0 should be carried over by hand if necessary.
* src/configfile.c,src/content.c,src/control.c,src/database.c,
  src/dynamicstring.c,src/fetch.c,src/filter.c,src/group.c,
  src/itemlist.c,src/lock.c,src/outgoing.c,src/over.c,src/post.c,
  src/pseudo.c,src/request.c,src/util.c: Minor includes rearrangement.
	
Tue Oct 30 2001 Jim Hague <jim.hague@acm.org>

* src/content.c: When generating temp file to write new content to, make
  sure there is no possibility of a name clash with an existing file.
  Bug spotted by Mirko Liss.

Tue Oct 30 2001 Jim Hague <jim.hague@acm.org>

* noffle.conf.example,docs/noffle.conf.5,src/configfile.h,src/configfile.c,
  src/protocol.c: Add new config item 'hostname' to specify the part after
  the @ in message IDs generated by Noffle. Patch submitted by Mirko Liss.
	
Tue Oct 30 2001 Jim Hague <jim.hague@acm.org>

* docs/noffle.conf.5,src/configfile.c,src/filter.h,src/filter.c:
  Contrary to the documentation, the action of a filter if not specified
  was 'full'. Add a new 'default' action which makes the action that of the
  group's subscription mode. Make this the default action, and allow
  'default' to be specified explicitly as the action in the filter
  definition. Adapted from patch submitted by Mirko Liss. Thanks, Mirko.
* docs/noffle.conf.5: Correct small typo.
	
Mon Oct 22 2001 Jim Hague <jim.hague@acm.org>

* src/fetch.c: Only leave articles in the requested list if the error
  fetching them was fatal. Otherwise article requests will accumulate
  indefinitely (e.g retrieving through NNTPcache when it can't find
  the body of an article, now or event. Yes, this happened to me; I
  had nearly 2000 requests backed up and never being cleared).
* src/group.c: The weekend's change introduced code that causes a bus
  error on Sparc ( *(time_t *)p = xxx ). Replace with a safe memcpy,
  and also use memcpy when reading the Entry and time items to remove
  warnings on Sparc compilation.
	
Sun Oct 21 2001 Jim Hague <jim.hague@acm.org>

* docs/noffle.conf.5,src/noffle.c: Duh! Do unsubscribing the simple way.
  Auto-unsubscribe when the last access time is more than the threshold
  number of days behind the time the last article arrived.
	
Sat Oct 20 2001 Jim Hague <jim.hague@acm.org>

* src/group.h,src/group.c,src/noffle.c,src/server.c: Grp_setLastAccess is
  only ever called with last param as time(NULL), so remove it and call
  time() inside the implementation of Grp_setLastAccess.
* src/client.c,src/group.h,src/group.c,src/noffle.c,src/post.c: Groups are
  automatically unsubscribed when the last access to the group is older
  than a particular threshold. However, for very low traffic groups, the
  last access may exceed the threshold simply because there has been no new
  article posted. In this case, rather than unsubscribe, update the group
  last access time. This means that groups are now only unsubscribed if
  the last access exceeds the threshold AND articles have arrived in the
  group since. Add Grp_setLastPostTime() to track the last time an article
  arrived in the group.

Fri Oct 05 2001 Markus Enzenberger <me@markus-enzenberger.de>

* src/configfile.c: fix bug with missing initialization of user name and passwd

Wed Sep 12 2001 Jim Hague <jim.hague@acm.org>

* src/client.c,src/client.h,src/fetch.c,src/noffle.c,src/server.c:
  robustness - instead of returning simple Passed/Failed statuses from
  connection functions, return an integer status instead. This allows
  Noffle to distinguish between a connection failure, an unrecoverable
  protocol error and a recoverable problem. As a concrete instance, Noffle
  will no longer abort the connection if a group is removed from the
  upstream server. Also beef up error detection a bit.
* src/content.c: instead of overwriting the existing content file(s) when
  updating - which leaves a window where Noffle is vulnerable to failure
  which will leave the content file corrupted (yes, it happened to me),
  write a new content file and rename it over the old file only when it
  has been written and closed with no errors reported.
	
Sat Sep 01 2001 Markus Enzenberger <me@markus-enzenberger.de>

* src/client.c,src/protocol.h: perform authentication at connect time,
  accept new and deprecated authentication status codes.

Sun Aug  5 2001 Jim Hague <jim.hague@acm.org>

* src/client.c: Change variable only used on constant to 'const'.
* src/filter.c: Add a couple of 'return's after ASSERT() to remove
  compiler warnings about functions needing returns.
* NEWS,TODO,configure,configure.in,noffle.conf.example,docs/NOTES,
  docs/noffle.conf.5,src/client.c,src/configfile.c,src/content.c,
  src/control.c,src/database.c,src/fetch.c,src/fetchlist.c,src/filter.c,
  src/group.c,src/lock.c,src/log.c,src/log.h,src/noffle.c,src/outgoing.c,
  src/post.c,src/protocol.c,src/request.c,src/server.c,src/util.c:
  Debug logging is always compiled and selected via noffle.conf. All debug
  logs are classified as all, none, config, control, expire, fetch,
  filter, newsbase, noffle, post, protocol, requests and server.
* src/util.c: Remove case sensitivity in date parsing.

Tue May 15 2001 Jim Hague <jim.hague@acm.org>

 * src/client.c: Only bail out of fetching multiple articles if the
   connection fails. If we do get a status from the upstream server
   note it and see what is reported for the next article. Otherwise
   failure to retrieve one article will cause all successive article
   fetches to fail even through they would succeed if tried.
 * src/lock.c: Fix assert in lazy locking. If another noffle signalled us
   to release the lock at the next close, and then repeats the signal so that
   it arrives during LOCK_closeDatabases, the signal handler was trying
   to close the databases again.
	
Thu May 10 2001 Jim Hague <jim.hague@acm.org>

 * src/client.c: Only return failure getting NEWGROUPS if the connection
   failed. If the server doesn't implement NEWGROUPS correctly (step
   forward elderly versions of NNTPcache) it isn't fatal to the
   fetch process. You can still do a 'noffle --query groups' to update
   your newsgroup list.
 * src/server.c: Correct error code given when article requested by
   message ID is not found. Previously the code given (423) was the same
   as for when an article requested by its number in a group was not
   found. The docs (and various NNTP servers) say 430 should be returned.
   Thanks to Alberto Mardegan <amardegan@iol.it> for spotting that.

Wed May  9 2001 Jim Hague <jim.hague@acm.org>

 * TODO,src/client.c,src/client.h,src/fetch.c,src/fetch.h,src/noffle.c:
   Improve error checking during fetches. A fetch is now aborted immediately
   if the connection times out or if an unexpected response arrives.
   This should fix problems with articles appearing in the wrong group,
   and possibly other mysterious happenings.
	
Tue May  8 2001 Jim Hague <jim.hague@acm.org>

 * src/post.c: If post-locally is set, only do immediate local posting
   on groups with status 'y'. We don't want to post locally articles
   destined for the moderator of a moderated group.
	
Tue May 01 2001 Markus Enzenberger <me@markus-enzenberger.de>

 * src/server.c: do not search all groups if group does not
   exist and contains no wildcards
 * AUTHORS: update my email address
 * configure.in,configure: changed version to 1.1-unstable-develop

Tue Mar 13 2001 Markus Enzenberger <me@markus-enzenberger.de>

 * src/client.c: Fix bug. Server name was not yet initialized
   if server required authentication at connect time.

Wed Feb 28 2001 Markus Enzenberger <me@markus-enzenberger.de>

 * src/database.c: fix missing argument to snprintf

Sun Feb 26 2001 Matija Nalis <mnalis-sf@voyager.hr>

 * fix for small glitches in options parting in src/noffle.c

Sun Feb 25 2001 Jim Hague <jim.hague@acm.org>

 * TODO,content.c,lock.c,server.c,server.h: Remove bug notice re:
   need to do a Cont_write on Lock_closeDatabases in case of unwritten
   content changes when releasing the lock. Update content to keep dirty
   flag and avoid unnecessary writes, and lock to signal server to re-read
   its group content info after the lock is released. Do NOT write content
   info on Lock_close if dirty, as the placeholder article in unsubscribed
   groups is currently done by adding it to the content when joining the
   group and deliberately not saving it unless another content modification
   takes place and thus causes the content to be saved.

Thu Jan 25 2001 Jim Hague <jim.hague@acm.org>

 * src/client.c,src/protocol.c,src/util.h,src/util.c: Common up
   repeated signal handler setting code into Utl_installSignalHandler.
 * src/client.c: Ensure Client_retrieveArt always exits with the global
   lock held. Previously it would be held on error, not held if OK.
 * src/lock.h,src/lock.c,src/noffle.c: Add lazy lock release. Only release
   the lock and close the databases if (a) another process signals us
   SIGUSR1 indicating it wants the lock, or (b) it is explicitly requested by
   a call to new function Lock_syncDatabases(). When waiting for the lock,
   SIGUSR1 the holding process every second. This is all an attempt to
   minimise the number of times we need to close and open the database.
   When (ha!) the database is replaced by something that can handle
   multiple simultaneous writers (with appropriate locking) this won't
   be necessary.

Fri Dec 29 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/server.c: apply bug-fix for lazy group loading by Matija Nalis 
 * TODO: Add handling of connection breakdown during a fetch to later
   section.

Fri Dec 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * AUTHORS: add Matija Nalis

Sun Dec 10 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/client.c: Extract common code from putCmd and putCmdNoFlush,
   reset client.lastStat when sending new command

Tue Dec 05 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

    * src/fetch.c,src/Makefile.in: use sendmail instead of mail

    * src/fetch.c,src/pseudo.c,src/pseudo.h,src/server.c: applied
    patch from Matija Nalis: better handling of inconsistent counters
    at remote server; do not read overview on each group command

Thu Oct 26 21:42:45 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/protocol.c: Fix bug in Prt_getLn if we should read a line
   starting with '\0' - according to the leafnode mailing list,
   this has been seen in the wild.
 * docs/inews.1,docs/noffle.1,docs/noffle.conf.5,
   packages/redhat/noffle.spec,src/configfile.h,src/configfile.c,
   src/noffle.c,src/post.h,src/post.c: Removed use of getopt_long,
   and added inews mode - the Noffle executable behaves
   as inews if invoked as inews. This includes adding From: and
   Organization: headers if necessary - add configs to override
   defaults for the From: domain and specify the organization.
   For all my fellow trn-heads out there, and users of any other
   ageing newsreader that expects inews. Updated RPM spec to create 
   inews link to noffle on install.
 * src/server.c: When replying to a command, generate the reply into
   a buffer, release the lock and then send the reply, so we don't
   hog the lock should the reply stall for some network reason.

Sun Oct 15 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * acconfig.h,config.h.in,configure.in,src/Makefile.in,src/fetch.c:
   Applied patch by Paul Slootman: using the mail program is
   replaced by sendmail (SENDMAILPROG variable).

Sun Sep 10 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * docs/NOTES: Added section about Gravity (thanks to
   Tomislav Filipcic <tfilip@jagor.srce.hr>).

Sun Sep 10 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/Makefile.am: Added filter.c, filter.h
 * src/fetch.c: Fixed a bug in Fetch_init, that triggered
   an assertion if connection to remote server failed.

Sat Sep 02 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * NEWS,src/client.c,src/protocol.c,src/protocol.h,src/server.c:
   Added timeout to Prt_getLn to avoid Noffle hanging if the
   connection breaks down during a fetch.

Wed Aug 23 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/post.c: do no longer always replace invalid message-IDs.

Wed Aug 16 00:03:50 BST 2000 Jim Hague <jim.hague@acm.org>

 * Permit 'k' and 'm' suffices after numbers in filter rules.
 
Fri Aug 11 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/noffle.c: Minor bug fix. Noffle no longer tries to unsubscribe groups
   that are already unsubscribed.

Wed Aug  9 22:02:21 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.c: Use plain LIST instead of LIST ACTIVE if possible
   for compatability with old servers.
 * src/client.c,src/fetch.c: Fix fetching bugs that could potentially
   have left the lock in the wrong state.
 * docs/noffle.conf.5,src/Makefile.in,src/client.c,src/configfile.c,
   noffle.conf.example: Add first-cut article filtering. Note you will
   need to run 'configure' again to re-generate src/Makefile.
	
Wed Jul 26 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * Released version 1.0pre7

Tue Jul 25 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/client.c: Added GMT to NEWGROUPS command.

Mon 24 Jul 20:30:05 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/database.h,src/database.c,src/server.c: Redo XHDR and
   XPAT to handle 'XHDR <msgid>' and 'XPAT <msgid>'. Common up
   code shared by XHDR and XPAT.
 * src/server.c,packages/redhat/noffle.spec: Remove pipe through
   sort(1) in printGroups() and dependency on textutil(RedHat)/
   textutils(SuSE) packages in RPM. The RPM now works on RedHat
   and derivatives and SuSE.
 * src/server.c: Release lock while collecting POST article and while
   reporting XOVER x-y results.
 * src/server.c: Update group 'last accessed' timestamp when XOVER read.
   This for smooth working with 'trn' and other newsreaders that only
   read the XOVER unless an article read. I have newsgroups I want to scan
   but only infrequently read an article - I don't want them getting
   unsubscribed.
 * src/server.c: Change server read timeout to 2 secs, release the lock
   if we'v held it for 2 secs so we don't starve anybody else, and
   if reading a command when we don't hold the lock don't use timeout.
 * src/util.c: Fix Utl_newsDate and Utl_parseNewsDateto work properly
   in all timezones.
 * src/lock.h,src/lock.c,src/noffle.c: Add 'fetch' lock to main lock,
   add Lock_gotLock() so we can test the main lock state (currently used
   only in ASSERTs). Fetch lock can be obtained WAIT or NOWAIT - latter
   fails immediately if lock not available.
 * src/client.c,src/fetch.c,src/noffle.c: Change lock handling during a fetch.
   Begin by obtaining 'fetch' lock - if busy, exit fetch immediately with
   error message. Then during fetch release the lock except when processing
   received data; in cases when incoming data is multi-line, collect all
   data first and then process. The aim is to ensure the lock isn't held
   with a network operation is in progress. I may carry on and extend this
   to all server operations as well (so a slow client can't hog the lock).
 * docs/noffle.conf.5,src/configfile.h,src/configfile.c,src/post.c,
   src/protocol.h,src/protocol.c: Add Path: header to newly posted
   articles. Provide default content - path-header in config overrides.
	
Sat Jul 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * doc/NOTES: Removed section about GNUS hanging. It was caused
   by the "select" bug in Noffle.

Sat Jul 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/server.c, src/protocol.c: Fixed a critical bug. "select" cannot
   be used with buffered stdio. This caused Noffle to hang with some
   readers (like tin).
	
Sat Jul 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de> 

 * request.c: Applied patch from M.Nalis:
   Modify Req_add() to append to requested/news.serv.er file each MsgID (and
   do not clean dirty flag, because otherwise writeRequestfile() would nuke us
   when overwriting file!).

Wed Jul 19 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * Applied patch from M.Nalis for fixing a small problem with
   the printed counters while fetching articles. 

Wed Jul 19 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * Do not acquire global lock for printing help

Mon Jul 17 11:19:06 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.h,src/client.c,src/noffle.c,docs/noffle.1: Remove
   '--query times' option. Creation time should always be time of
   creation on local server.
 * src/group.h,src/group.c: Remove Grp_setCreated().
	
Fri Jul 14 2000 Matija Nalis <mnalis-sf@voyager.hr>

 * Added counter for --fetch so one can see how much it is until the
   end of the transfer.

Fri Jul 14 15:20:14 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.c,src/fetch.c,src/noffle.c: The groupinfo.lastupdate file
   was being used to (a) indicate the time of the last addition to group
   information, and (b) the last access to a server. With more than one
   server specified, (a) meant the groupinfo.lastupdate file was updated
   when new groups on the server (or a new fetch of the server group list)
   were processed. When server 2 came to use the file for (b) (to determine
   the time to specify when sending the NEWGROUPS command), the time was
   already set by server 1 and so server 2 would not see new groups. Fix
   this by creating lastupdate.<server> files for use (b).
 * src/client.c,src/group.c: Set initial group creation time to the current
   time. Previously it was set to 0, so new groups were not reported to a
   NEWGROUPS request unless 'noffle --query times' was run - even then,
   local groups would never be reported. Setting the creation time to the
   creation time on the local server makes things work properly. NB - the
   group creation time should always be reported as the creation time on
   the server; must fix this and remove '--query times'. This change will
   require 'noffle --query groups' to be re-run to create the server
   lastupdate.<server> files.

Mon Jul 03 12:05:50 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/database.h,src/database.c,src/server.c: Fix 'XHDR <msgId>' and
   add 'XPAT <msgId>'. 'XHDR <msgId>' previously only worked if
   msgId was a message in the current group. My brain was really
   in neutral when I did that.

Fri Jun 30 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

  * src/server.c: Leave online mode, if the connection to a remote server
    fails for avoiding a series of timeouts and holding the lock for
    a long time.

Sun Jun 25 09:45:50 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/protocol.c: Another go at Prt_genMsgId. Yesterday I seeded the
   random element of the generated message id from the time; but what
   if two Noffle processes start in the same second? So switch to seeding
   with tv_usec instead.
	
Sat Jun 24 21:21:47 BST 2000 Jim Hague <jim.hague@acm.org>

  * packages/redhat/README, packages/redhat/noffle-expire,
    packages/redhat/noffle.spec: Initial versions.
  * src/noffle.c, docs/noffle.1: Remove --post (local|all)
    and replace with just --post. 'Approved:' header recognition
    removes need for --post varieties.
  * src/post.c: 'Approved:' header recognition, post to all external
    servers not just first, check all groups for post access before
    posting to one.
	
Sat Jun 24 20:45:52 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/noffle.c: Set last accessed time on group when subscribed
   from command line.
 * src/post.c: Bugfix - Post_close on duplicate article post.
 * src/protocol.c: Fix bug in Prt_genMsgId that caused duplicate
   message IDs to be generated for posts in the same second.

Sat Jun 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * doc/NOTES: Removed section about GNUS hanging. It was caused
   by the "select" bug in Noffle.

Sat Jun 22 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/server.c, src/protocol.c: Fixed a critical bug. "select" cannot
   be used with buffered stdio. This caused Noffle to hang with some
   readers (like tin).
	
Mon Jun 19 22:43:38 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/util.c, src/database.c: Fix header line reading bug.

Tue Jun 13 21:31:32 BST 2000 Jim Hague <jim.hague@acm.org>

  * src/noffle.c: Add include <sys/time.h> before sys/resource.h.
    Man page says you need it, FreeBSD won't compile without it.
  * src/client.c: Remove SA_INTERRUPT flag set from installSignalHandler.
    It is flagged as a no-op in the Linux headers, and does not exist
    on FreeBSD or Solaris.
  * src/configfile.h, src/configfile.c, src/protocol.h, src/protocol.c,
    src/post.c, docs/noffle.conf.5: Add 'path-header' and addition
    of Path: header to posted articles if required.
	
Tue Jun 13 07:27:21 BST 2000 Jim Hague <jim.hague@acm.org>

  * src/configfile.h, src/configfile.c, src/database.c: Redo config
    expires routines to remove enumerator and replace with routine to
    obtain expire time for specified group.
  * src/configfile.h, src/configfile.c, src/server.c, noffle.conf.example,
    docs/noffle.conf.5: Change 'auto-subscribe-mode' to
    'default-auto-subscribe-mode' and add
    'auto-subscribe-mode <grp pattern> <mode>'. For the moment,
    spot old usage of 'auto-subscribe-mode' and interpret it as
    'default-auto-subscribe-mode'.
  * src/client.c: Rename variable to remove compiler warning.
	
Sat Jun 11 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * Prepare for version 1.0pre6
 * configure.in: Removed warning options for warnings that are
   unavoidable with libgdbm

Mon Jun  5 09:46:30 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.c, src/fetch.c, src/group.c, src/group.h, src/noffle.c:
   Don't track remote message number read unless subscribed to a group.
   This stops 'Missing articles' pseudos being generated when you join
   a group some time after doing the 'noffle --query groups' that first
   found the group, or if you resubscribe a while after unsubscribing.
   They will still be generated if articles are missed when a group is
   subscribed, in which case the pseudo message is entirely applicable.
	
Sat Jun 03 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * docs/NOTES: removed the whole section about the mail2news gateway.
   It doesn't really work, because procmail forks for each mail and
   changing the posting allowed status is not atomic.

Thu Jun 01 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * docs/NOTES: Added section about "replace-messageid" option in
   the Mail-News-Gateway chapter.

Mon May 29 19:12:47 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.c: Fix spelling mistake in comment.
 * docs/noffle.1: Add a little bit more to the description of --online.
	
Mon May 29 18:28:25 CEST 2000 Uwe Hermann <uh1763@bingo-ev.de>

 * configure, configure.in: Changed the --enable-debug option of configure.
   It now accepts the parameters 'no', 'min' and 'yes', i.e. no compiler-
   warnings, minimum compiler-warnings and maximum compiler-warnings.
   Default is 'min'. Stable releases should have 'no' as default, IHMO.

 * NEWS: Update.

Fri May 26 11:38:27 BST 2000 Jim Hague <jim.hague@acm.org>

 * docs/NOTES: Added notes on knode.
 * src/client.c: Corrected comment.
	
Thu May 25 22:03:56 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/post.c: Fixed stupid bug in article checking code where a
   correctly formatted Date: line would have the "Date: " removed
   before writing the outgoing file. Remote servers, not unnaturally,
   get upset about this. Mea culpa :-(
	
Sat May 20 22:10:48 CEST 2000 Uwe Hermann <uh1763@bingo-ev.de>

 * docs/Makefile.am, docs/Makefile.in: Added INTERNALS to docs/Makefile.am, so
   that it is included in the distribution by 'make distcheck'.

 * docs/NOTES: Added info about pan versions 0.7.6 and 0.8

Sat May 20 11:46:54 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/client.c: Closer perusal of Son Of RFC1036 reveals that
   Supersedes: can have multiple message IDs. Do this.
	
Sat May 20 2000 Markus Enzenberger <markus.enzenberger@t-online.de>
 * src/noffle.c: always enable generation of core files.

Fri May 19 14:02:44 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/util.h, src/util.c, src/database.c, src/pseudo.c, src/post.c:
   Redo Utl_rfc822Date to not use strftime - this was potentially
   wrong as it would only generate a conformant date string in
   English locales - and rename to Utl_newsDate because the date format
   is actually a subset of RFC822 - see Son Of RFC1036. Also add
   Utl_parseNewsDate, ensure the date on posted articles is conformant
   and replace if not, and implement observance of Expires: headers.
 * src/client.c: Observe Supersedes: headers on incoming articles.
 * src/content.c: Ensure if last article(s) in group are cancelled that
   article numbers aren't re-used.
 * docs/INTERNALS: Move INTERNALS to docs/.
	
Thu May 18 13:22:36 BST 2000  Jim Hague <jim.hague@acm.org>

 * Recognise explicit posting statuses of 'y', 'n' and 'the rest'.
   The latest IETF draft says you can have other statuses apart from
   'm' (moderated group), and these should probably be treated in the
   same way as 'm', i.e. forwarded to the external server to worry
   about.
	
Wed May 17 21:19:19 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/configfile.h, src/configfile.c, src/post.h, src/post.c,
   src/noffle.c, src/server.c, docs/noffle.1, docs/noffle.conf.5:
   Moved all article posting code into post.[hc], removed
   'remove-messageid' option, added '--post' to noffle command line.
   Added 'post-locally' option. docs/NOTES still needs updating.
   Needs more testing too.
	
Wed May 17 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * README: Clean-up and update.
 * docs/noffle.conf.5, src/configfile.h, src/server.c:
   Disabled remove-msgid option.

Mon May 15 11:21:28 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/configfile.h, src/configfile.c, src/client.c, docs/noffle.conf.5:
   Added getgroups and omitgroups options.
	
Sun May 14 16:51:24 BST 2000 Jim Hague <jim.hague@acm.org>

 * docs/NOTES: Added notes on trn, xrn and knews.
 * src/configfile.h, src.configfile.c, src/server.c, docs/noffle.conf.5:
   Increment the article number of the gen info article in groups that
   are not auto-subscribed each time the gen info article is read. The gen
   info article thus remains unread at the start of every newsreading
   session. This behaviour can be disabled by setting new config
   setting 'info-always-unread' to 'no'. Default is 'yes'. This (I hope)
   restores Markus's preferred behaviour.
 * INTERNALS: Added file with some rough jottings on the internals of Noffle.
   A work in (probably sporadic) progress.

Sun May 14 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/fetch.c: Did some refactoring.

Sat May 13 15:09:01 BST 2000 Jim Hague <jim.hague@acm.org>

 * src/itemlist.c: Fixed stupid, Stupid, STUPID bug in Itl_next().
   Redid itemlist code slightly to remove need to keep separators
   string, at the cost of making it impossible to use '\1' as a
   separator. I don't think this will be a problem.
 * src/log.h, src/log.c, src/over.h, src/over.c: Adjusted consting
   in Log_init and new_Over to remove compiler warnings.
 * src/portable.h, src/server.c, src/client.c: Introduced UNUSED(x)
   macro to indicate deliberately unused function parameters and
   remove warnings.
 * src/content.c: Preserve gen info in Cont_write() provided it is
   followed by an article with the next number. Stops gen info article
   vanishing instantly on reading when auto-subscribe is on, which
   was sort-of confusing for users (why can't I read that again?)
   and caused xrn to complain the NNTP server was broken.

Sat May 13 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/client.c: Rewrote needsMark(): uses itemlist.h, more debugging output.
 * src/server.c: Rewrote getTimesInSeconds(): arguments ar now int and
   checked with assertions. Return value is time_t and must be checked
   for (time_t)-1.

Sat May 13 06:20:01 CEST 2000 Uwe Hermann <uh1763@bingo-ev.de>

 * src/Makefile.am, src/Makefile.in: Added portable.h to the list of sources.
   I forgot this in my last commit. Sorry.

Fri May 12 2000 Markus Enzenberger <markus.enzenberger@t-online.de>

 * src/client.c: add some intermediate variables for easier debugging
   in needsMark(). It seems that thread mode is sometimes not working.
 * src/client.c, src/content.c, src/dynamicstring.h, src/dynamicstring.c,
   src/util.h, src/util.c, src/protocol.c:
   Changed some variable types and used some casts to avoid compiler
   warnings about signedness. In general, int should be used for parameters
   for allowing a signedness assertion in the function.
   (see J.Lakos: Large-Scale C++ Software Design, section 9.2).
 * src/client.c, src/database.c, src/database.h, src/fetch.c, src/fetchlist.c,
   src/fetchlist.h, src/group.c, src/group.h, src/noffle.c, src/server.c
   src/server.h:
   Renamed some variables, because they caused compiler warnings because
   of shadowing global variables from system include files
   (index, stat, serv).
 * src/fetchlist.c:
   Avoid compiler warning because of cast from const to non-const.
 * src/post.c, src/server.c:
   Avoid compiler warnings about incomplete initializer blocks.
	
Fri May 12 10:19:56 CEST 2000  Uwe Hermann <uh1763@bingo-ev.de>

 * configure, configure.in: Only add all those compiler-switches
   like -ansi, -pedantic etc. if we use gcc. Other c-compilers are unlikely
   to have those switches.


Wed May 10 00:25:44 CEST 2000  Uwe Hermann <uh1763@bingo-ev.de>

 * src/client.c, src/configfile.c, src/content.c, src/control.c,
   src/database.c, src/dynamicstring.c, src/fetch.c, src/fetchlist.c,
   src/group.c, src/itemlist.c, src/lock.c, src/log.c, src/noffle.c,
   src/online.c, src/outgoing.c, src/over.c, src/post.c, src/protocol.c,
   src/pseudo.c, src/request.c, src/server.c, src/util.c:
   Added portable.h #include.

 * src/client.h, src/database.h, src/fetch.c, src/group.h, src/lock.c,
   src/outgoing.c, src/over.c, src/over.h, src/pseudo.c, src/server.c,
   src/util.c, src/util.h: Added some #ifdefs to correctly include either
   time.h or sys/time.h or both, depending on which are found.

 * src/noffle.c: Changed the return-type of the signal-handlers bugReport()
   and logSignal() to RETSIGTYPE, which is either void or int, depending on
   the system you compile on (autoconf #defines the RETSIGTYPE).

 * src/portable.h: Added file. This #defines some macros, so the code uses
   __snprintf() and __vsnprintf if snprintf and vsnprintf aren't available.
   This is the case on SunOS, for example.


Sat May  6 12:25:39 BST 2000  Jim Hague <jim.hague@acm.org>

 * src/server.c: Changed XOVER with no arg. to return info for current
   article, not error.

 * src/server.c, src/content.h, src/content.c: XHDR - added 'xref' to
   headers recognised to keep trn happy, and recognise message ID argument.

 * src/server.c, src/content.c: Ensure first/last from LIST ACTIVE and
   GROUP agree (trn uses former). Tricky with pseudo gen info articles
   around. Presence of these now only recorded in content and not
   reflected in group first/last until proper article posted after
   pseudo.

 * src/client.c, NEWS: Reinstated starting article numbering from first
   article number on server. Reasoning below is wrong except in exceptional
   circumstances (e.g. join group, auto-subscribe, manual unsubscribe,
   auto subscribe again, etc. to get > 2 Noffle info messages in group.
   Bring reader up to date, remove & reinstall Noffle. Join group,
   autosubscribe after more news arrives at server, reader thinks it has read
   n articles it hasn't, where n is number of Noffle info messages in
   group first time round - 2). Feature is generally useful, esp. in
   development, so back in it goes.

 * src/group.c: Forget cached group info when group database closed.
	

Sat May  6 01:31:04 CEST 2000  Uwe Hermann <uh1763@bingo-ev.de>

 * Makefile.in, configure, configure.in, docs/Makefile.in, src/Makefile.in:
   Added checks for the mail and sort programs. ./configure will abort if
   they're not found.

 * README: Removed the paragraph about news client software, as it's the same
   as the one in docs/NOTES.

 * TODO: Removed 'expiring by groups' and
   'move some text from noffle.1 to noffle.conf.5'.

 * docs/NOTES: Changed the text about -DDEBUG to explain one should use
   './configure --enable-debug'.

 * docs/noffle.1, docs/noffle.conf.5: Minor fixes. Added myself and Jim Hague
   to the AUTHORS section :-)

 * src/client.h, src/common.h, src/configfile.h, src/content.c, src/content.h,
   src/control.c, src/control.h, src/database.h, src/dynamicstring.c,

   src/post.h, src/protocol.h, src/pseudo.h, src/request.h, src/server.h,
   src/util.c, src/util.h: Added the <config.h> include.

 * src/content.c: Added missing include "content.h". Added a missing 'void'
   in the declaration of clearCont().

 * src/fetchlist.c: Casted fetchlist.size to (size_t) in a call to qsort(),
   as qsort() expects a size_t. This removes a warning.

 * src/noffle.c: Made doRequested() static. Added missing void to
   enableCorefiles().

 * src/log.c, src/protocol.c, src/online.c, src/pseudo.c: Added missing
   includes.

 * src/pseudo.c: Made genOv() and genPseudo() static.

 * src/server.c: Added missing void to postArts(). Made touchArticle() static.

 * src/util.c: Casted arguments of malloc() and memcpy() to size_t.

 * src/dynamicstring.c, src/itemlist.c, src/over.c, src/request.c, src/util.c: 
   Removed casting of the result of malloc(). This is not necessary and
   can hide a missing include of <stdlib.h>.

   They are used by aclocal, autoheader, autoconf and automake.

 * src/config.c, src/config.h: Renamed to configfile.c and configfile.h,

   src/protocol.c, src/request.c, src/server.c: Files now #include <config.h>.
   Added missing <stdio.h>. This removes the warnings about snprintf() not
   being declared.

 * Makefile: Removed. This is now generated by configure.

 * AUTHORS.html, CHANGELOG.html, COPYING.html, README.html, FAQ.html,
   NOTES.html, INSTALL.html: Removed files.
 
 * AUTHORS, COPYING, ChangeLog, README, INSTALL, NEWS, docs/FAQ, docs/NOTES:
   Added files.

 * TODO.TXT: Renamed to TODO. Slightly changed formatting.

 * README: Reformatted the file. Added info about CVS. Added a pointer to
   the file INSTALL.

 * noffle.1, noffle.conf.5: Moved to docs/

 * LSM.TXT: Moved to docs/noffle.lsm. Small fix.

 * INSTALL: Adapted to autoconf build-system. A few minor fixes.


-------------------------------------------------------------------------------

1.0pre6pre

     * Forget cached group info when group database closed.
     * Added list of 'forbidden' newsgroup specs., as defined in draft IETF
       Newsgroup Format (C.Lindsey), tracked to replace RFC1036. This defines
       newsgroup names that should only be used for server-local groups and
       server pseudo-groups (e.g. INN's to.*, cancel, cancel.*, junk). These
       are now intercepted when querying server groups and ignored. Group names
       omitted are any single component names, any 'control.*', 'to' or
       'to.*',and any with a component 'all' or 'ctl'.
       Note these restrictions do not apply to local group names.
     * Fixed problem with article numbering if the overview file empties,
       e.g. due to all articles in a very low volume group expiring. This
       would cause article numbers to be set back to 1 when a new article
       arrives.
     * Changed %i to %d in sscanfs everywhere. INN often (as it is entitled
       to do) has leading zeros on numbers. %i interprets these as octal
       numbers. Also changed %i to %d in printfs, for no good reason.
     * New groups now always start numbering at article 1. Previously article
       numbering would start with the first held remote article number, in an
       attempt to avoid newsreaders noticing if noffle is deleted and
       reinstalled. Given Noffle may well not collect the first held article
       anyway - it only will if the default number of articles to retrieve on
       a first connect is big enough - and the fact that Noffle's pseudo
       articles make it impossible to keep local article numbers in lock-step
       with the server, there is the chance this scheme would just cause
       readers to miss new articles.
     * Record newsgroup posting status. Enforce it at posting time.
       Added --modify to change newsgroup descriptions for all groups and
       posting status for local groups.
     * Added group deletion.
     * Added message cancellation - from command line or by control message.
       Note command line only cancels locally - it can't be used to cancel a
       message that has already gone offsite. A control messages cancels
       locally if possible; it is only propaged offsite if the target is in a
       non-local group and has itself already gone offsite.
     * Added wildmat code taken from INN - ensure Noffle wildcarding is
       exactly to spec.
     * Added group-specific expire times.
     * Noffle now sends a "MODE READER" command after connecting to the
       remote server. INN needs this before it will permit POST.
     * Applied patch from Jim Hague: support for local groups / new command
       line options --create and --cancel.
     * Changed output of 'noffle -a all' to standard mailbox format,
       so that tools like grepmail work.

Version 1.0pre5

     * Core files are always enabled when running as server and debugging
       symbols are always in the executable.
     * Use GDBM_FAST flag for hash files.
     * Fixed a bug in online mode with servers that need authentication.
     * Minor changes and improvements

Version 1.0pre4

     * Fixed a bug that broke cross-posting of articles
     * Fixed a bug that truncated headers of posted articles.
     * Long overview header lines are now split into multiple lines in
       response to HEAD or ARTICLE commands.
     * Fixed a bug that caused a crash sometimes when updating the
       requested article list after releasing/regetting the global lock
     * Server is now allowed to generate core files on crash (in spool
       directory) if compiled with -DDEBUG option
     * Opening an article additionally marks all references as
       interesting, so more articles are fetched in thread mode, if one
       article of a thread was opened.
     * New config option "connect-timeout"
     * Minor improvements and bug-fixes

Version 1.0pre3

     * Added XPAT command. Not full syntax, but enough for making slrn's
       thread reconstruction work
     * Storing of requested message-ids completely rewritten (thanks to
       Volker Wysk for the patch). Much more efficient now. Bug removed
       that broke requesting articles with message-IDs containing a
       slash. Added --requested option.
     * When fetching requested articles, do not send more than 20 ARTICLE
       commands at once, before parsing the server response.
     * Minor bug fixes and improvements.

Version 1.0pre2

     * Added RPM_BUILD_ROOT variable to Makefile (useful for creating RPM
       source packages)
     * Removed terrible bug that truncated article body after releasing
       and re-getting global lock

Version 1.0pre1

     * needs complete re-installing, some formats have changed
     * Support for multiple remote servers
     * Faster download when fetching news, because articles are prepared
       in database while parsing response to XOVER and all ARTICLE
       commands are sent at once
     * Bug removed that made authetication only work with lower-case
       passwords
     * Other small bug fixes and improvements

Version 0.19

     * Fix broken full mode
     * Fix cutting of articles after line beginning with '.'
     * Other bug fixes
     * LIST commands can have pattern argument now
     * initial-fetch option removed (same as max-fetch now)

Version 0.18

     * needs complete re-installing, most file format have changed
     * Group database uses gdbm, databases moved to
       /var/spool/noffle/data
     * Most config options changed their names, some do not longer exists
     * New fetch mode "thread" added
     * Different --fetch invocations replaced by single option
     * Meaning of "--database" option changed, "--article" option added
     * Failed postings are now returned to sender by "mail" command
     * Expire uses last access time
     * Auto-subscribe option only subscribes groups now, if an article
       body is opened (no longer if group is selected).
     * Improve posting at German T-Online provider: rename X-Sender
       header, Reply-To header is added, if missing (T-Online overwrites
       From headers), allow to remove Message-ID as a config option.
     * Doc files are now copied to $(PREFIX)/doc/noffle
     * Y2K compliance of NEWGROUPS command
     * Various bug fixes (thanks to all users helping with bug reports)
     * Various changes for tuning and improvement

Version 0.17

     * Bug removed that caused NOFFLE to exceed the allowed maximum number of
       open files on longer sessions.

Version 0.16

     * Noffle generates Message-ID if a message received for posting has none.
