    7 o  replying via email to an article with
    8    From: =?us-ascii?q?<a@example.com>,?= <b@example.org>
    9    will result in
   10    To: <a@example.com>, <b@example.org>
   11    [20141230 Urs Janssen <urs@tin.org>]
   12 
   13 o  get_respcode() doesn't handle the 401 response code. as we have to
   14    evaluate the response text as well we have to fix every
   15    nntp_command(..., NULL, 0) call.
   16    [20100429 Urs Janssen <urs@tin.org>]
   17 
   18 o  col_response is a misnomer as the counter doesn't count responses
   19    anymore (except on the very first article). The man-page is outdated too.
   20    [20080826 Urs Janssen <urs@tin.org>]
   21 
   22 o  'T'ag all parts of multipart message doesn't work (it never did)
   23    with thread_arts 4 (multipart) or 5 (percentage)
   24    [20080606 Urs Janssen <urs@tin.org>]
   25 
   26 o  cLINES < MIN_LINES_ON_TERMINAL || cCOLS < MIN_COLUMNS_ON_TERMINAL
   27    isn't checked on startup
   28    [20071210 Urs Janssen <urs@tin.org>]
   29 
   30 o  unexpected multiline responses confuse tin, e.g.:
   31    | 240 Article posted =?ISO-8859-1?Q?=3C=3D=3Fiso=2D8859=2D1=3Fq=3F=3F=3D87r7k8na?=
   32    |   =?ISO-8859-1?Q?vt=2Efsf=40urs=2Did=2Etest=2Eka=2Enu=3E?=
   33    (the servers response should be a single line (INN 2.2))
   34    [20050207 Urs Janssen <urs@tin.org>]
   35 
   36 o  better integrate saving of MIME/non-MIME articles when not using libuu.
   37    MIME sections are saved by the 's'ave operations, uuencoded sections
   38    are saved as part of the postprocess backend
   39    [mostly done]
   40    [Jason Faultless <jason@altarstone.com>]
   41 
   42 o  batch mode has several bugs
   43    - -Z and giving a cmd-line group the cmd-line group is not displayed in
   44      the statistics nor taken into account for the 'any unread news' status.
   45    - -vc could be more verbose (like -vcZ is)
   46    - -o currently is not a 'batch_mode' option
   47    [Urs Janssen <urs@tin.org>]
   48 
   49 o  add version number to other config-files (e.g. tin.defaults)
   50    and do the same checks as for TINRC_VERSION/tinrc. for the
   51    filter and attributes file store the charset the file is written in
   52    (e.g. ISO-8859-x vs. unicode) and for the filter file the filter method
   53    used (wildmat or regexp (or TRE))
   54    [Urs Janssen <urs@tin.org>]
   55 
   56 o  overview file caching code is over-complex
   57    - cache the original overview info instead of rebuilding it from
   58      the processed (decoded etc.) data, no matter if it's broken (e.g.
   59      contains raw 8 bit data) as we have to deal with that anyway. if there
   60      are no original overviews, cache the original data from the postings
   61      headers (after unfolding and tab removal).
   62    - Add docs to explain how to create system-wide overviews
   63 
   64 o  iso2asc conversion is missing for 'internal' strings (e.g. 'M'enu)
   65    [20020319 Urs Janssen <urs@tin.org>]
   66 
   67 o  comments in attributes get lost (we need to do something like we do for
   68    the filter file)
   69    [20080425 Urs Janssen <urs@tin.org>]
   70 
   71 o  if tin is falling back to HEAD/NEXT ([X]OVER not working) it doesn't honor
   72    tinrc.getart_limit
   73    [20090112 Urs Janssen <urs@tin.org>]
   74 
   75 o  the keys GroupToggleSubjDisplay and ThreadToggleSubjDisplay are misnamed,
   76    as they toggle the display of the sender address, not the subject.

   79 Pager Problems
   80 --------------
   81 
   82 Posting Problems
   83 ----------------
   84 o  8bit chars in some headers are RFC-2047-encoded where this is not allowed
   85    according to usefor (Newsgrous, Distribution, ...) - do_rfc15211522_encode()
   86    simply encodes all headers no matter if any of them must not be encoded
   87    (see parse_rfc822_headers()).
   88    [20090112 Urs Janssen <urs@tin.org>]
   89 
   90 o  the mime encoder may create two adjacent encoded words in the same line
   91    e.g.       Subject: =?UTF-8?B?4oKs4oKs4oKs?= =?UTF-8?B?IOKCrOKCrOKCrA==?=
   92    instead of Subject: =?UTF-8?B?4oKs4oKs4oKsIOKCrOKCrOKCrA==?=
   93    [20140513 Urs Janssen <urs@tin.org>]
   94 
   95 o  remove Message-IDs with 8bit chars in them when they occur in
   96    Message-ID or References header
   97    [done for References in replies/followups, Urs]
   98 
   99 o  keep RFC 6532 in mind as parts of it will sooner or later make it into
  100    NNTP (sic!).
  101    [20120220 Urs Janssen <urs@tin.org>]
  102 
  103 o  repost ('x') ignores ~/.tin/attributes - bug or feature?!
  104    [IMHO a bug as settings like mailing_list are essential, Urs]
  105 
  106 o  forged cancelling via Supersedes:/Also-Control:/Control:-header is possible
  107    if it is supplied by hand (inews_prog=--internal)
  108 
  109 o  when last articles in a newsgroup were cancelled, it shows that there are
  110    new articles in that group (except when using -n cmd-line flag)
  111 
  112 o  mailers other than sendmail (f.e. elm) and use_mailreader_i=OFF may lead
  113    to 'duplicated'-headers and multiple signatures
  114 
  115 New features
  116 ------------
  117 o  implement SAVE_APPEND_FILE_ALL ('A') and SAVE_OVERWRITE_ALL ('O') keys
  118    which just ask once if file(s) already exist (open_save_filename()).
  119    [20170811 Urs Janssen <urs@tin.org>]
  120 
  121 o  add second pipe command when piping multiple articles to use one
  122    pipe per article (currently it is one pipe for all). ':' could be
  123    used as key (only in use at the pager where this feature doesn't make
  124    sense).
  125    [20160412 Urs Janssen <urs@tin.org>]
  126 
  127 o  allow abort piping multiple articles, ESC/'z' just aborts the current
  128    one
  129    [20160409 Urs Janssen <urs@tin.org>]
  130 
  131 o  add per scope getart_limit via attributes
  132    [20131114 Urs Janssen <urs@tin.org>]
  133 
  134 o  add support for %A (Address), %C (Firstname), %N (Fullname) to
  135    group_format and thread_format
  136    (what about "conflicting" settings for show_author and %[ACIN]?)
  137    [20130925 Urs Janssen <urs@tin.org>]
  138 
  139 o  add a key to "drop" pending data from the server (either by
  140    disconnet/reconnect (fast but reconnect may fail due to rate limit or ...)
  141    or via calling drain_buffer() (might be slow if there is much pending
  142    data)) so one doesn't have to quit and restart tin if the client/server
  143    communication get's desynced (i.e by reading an article which has a non
  144    dotstuffed lone '.' in it or the like)
  145    [20130615 Urs Janssen <urs@tin.org>]
  146 
  147 o  x_body currently doesn't allow cmd. execution via ! like x_headers
  148    [20110912 Urs Janssen <urs@tin.org>]
  149 
  150 o  add nntp_default_server to tin.defaults to override compile time setting.
  151    if given strings starts with / or ~ the value is taken from the referenced
  152    file, if it starts with $ it is read from the referenced variable.
  153    [20101118 Urs Janssen <urs@tin.org>]
  154 
  155 o  the old space_goto_next_article=ON && space_goto_next_unread=OFF is not
  156    possible with the new goto_next_unread rc-var, we need something like
  157    an additional goto_next_read rc-var
  158    [20101101 Urs Janssen <urs@tin.org>]
  159 
  160 o  add DEFAULT_SIGDASHES_REGEX and related 'M'enu-entry for signature
  161    detection in cook.c
  162    [20080925 Urs Janssen <urs@tin.org>]
  163 
  164 o  give an error message if append_mail() fails (grep TODO post.c)
  165    [20080423 Urs Janssen <urs@tin.org>]
  166 
  167 o  allow remapping of the 'z' abort-key (lynx style) in wait_for_input().
  168 
  169 o  add user defined screen layout at different levels (e.g. posting
  170    history screen)
  171    (done for selection, group and thread level)
  172    [20041025 Urs Janssen <urs@tin.org>]
  173 
  174 o  add jump to article (if still available and Message-ID is known) to
  175    posting history screen
  176    [20170331 Urs Janssen <urs@tin.org>]
  177 
  178 o  allow a Message-ID on the cmd. line to jump to the given article
  179    [20170718 Urs Janssen <urs@tin.org>]
  180 
  181 o  add TLS (RFC 4642), NNTPS support
  182    (<http://www.gnu.org/software/gnutls/>, <http://www.openssl.org/>
  183     might be useful (but unfortunately we use fputs()/fgets() instead of
  184     read()/write() - BIO_*() may be useful);
  185     "stunnel -c -d 1119 -r news.example.org:563; tin -g localhost -p 1119"
  186     can be used for NNTPS)
  187    [20031210 Urs Janssen <urs@tin.org>]
  188 
  189 o  add more AUTHINFO SASL (RFC 4643, RFC 5802) support (DIGEST-MD5,
  190    EXTERNAL, ...) and a fallback if no libgsasl is found (e.g cyrus-sasl
  191    or a handrolled version for at least PLAIN)
  192    [20080316 Urs Janssen <urs@tin.org>]
  193 
  194 o  add XZVER (and XZHDR) support (zlib compressed yyencoded overview data)
  195    <http://helpdesk.astraweb.com/index.php?_m=news&_a=viewnews&newsid=9>
  196 
  197 o  make 'GNKSA'-parser RFC5322/USEFOR compliant and fix bugs
  198    (e.g. "<~$!~( )@( )example.com>" causes "illegal character in RHS", but
  199    the address is valid)
  200 
  201 o  the TLD checking in the 'GNKSA'-parser needs some rework, keeping the
  202    list of valid TLDs up to date is more or less impossible with the ~1400
  203    pending new TLDs
  204    [20131024 Urs Janssen <urs@tin.org>]
  205 
  206 o  add In-Reply-To threading for mailgroups
  207    [20030518 Urs Janssen <urs@tin.org>]
  208 
  209 o  make auto'S'ave also work for inrange groups
  210    (unfortunately 'S' at select level is used for something else)
  211    [20030508 Urs Janssen <urs@tin.org>]
  212 
  213 o  turn ask_for_metamail into $MM_NOASK support (see metamail(1))
  214    [20030314 Urs Janssen <urs@tin.org>]
  215 
  216 o  fetch overview data in chunks (e.g. 100 arts/chunk) to allow
  217    faster read interruption.
  218    [20020326 Dirk Nimmich <nimmich@muenster.de>]
  219 
  220 o  add bold-italic, bold-underline, italic-underline, bold-italic-underline
  221    word highlightings.
  222    [20020721 Urs Janssen <urs@tin.org>]
  223 
  224 o  allow bold, underline, italic, ... as colour substitution for
  225    monochrome terminals (map green=underline, italic=yellow)
  226    (see also
  227    <nntp://news.tin.org/20020416202232.A4575@bloatware.reston01.va.comcast.net>)
  228    [20030218 Serge Matveev <sm@cl.spb.ru>]
  229 
  230 o  hierarchical 'M'enu, e.g. put all art_marked_*into a 'submenu',
  231    restructure/sort 'M'enu items, some display-options (render BiDi) are
  232    currently under expert options, some options in display options are
  233    navigation options (catchup thread, use mouse, ...)
  234    [20020322 Urs Janssen <urs@tin.org>]
  235 
  236 o  add a postponed 'browser' (store postponed arts in MH or maildir
  237    format to make things easier?)
  238    [20020305 Dirk Nimmich <nimmich@muenster.de>]
  239 
  240 o  add postpone option for mail-actions;
  241    reusing p'o'stponed articles in mailing_list groups doesn't work
  242    (possible fix: store Newsgroups (and other info) via msg_add_header()
  243     (to overwrite any old values) in X-Tin-Postponed:-header and remove it
  244     before posting.)
  245    [20010623 Urs Janssen <urs@tin.org>]
  246 
  247 o  should the postponed 'file' (and posted messages 'file') be in
  248    mailbox_format (even if that's a one file/message format, thus
  249    the 'file' actually needs to be a directory?).
  250 
  251 o  add maildir/maildir++ support (besides MBOX{O,RD} and MMDF},
  252    MH (not only reading but also writing), mailstore, BABYL, Kendra (MMDF
  253    like with 20*CTRL-A as sep.), MBX and MIX (indexed MBOX from UW-IMAP)
  254    and add man-pages for the various formats.
  255    (see <http://www.ifi.uio.no/~larsi/notes/BABYL> for BABYL,
  256     <http://www.qmail.org/man/man5/maildir.html> for maildir,
  257     <http://www.qmail.org/man/man5/mbox.html> for MBOXCL and MBOXCL2,
  258     <http://www.washington.edu/imap/listarch/2000/msg00363.html> for MBX,
  259     <http://www.washington.edu/imap/documentation/mixfmt.txt.html for MIX)
  260    [20020215 Urs Janssen <urs@tin.org>]
  261 
  262 o  add $LOCKEXT support
  263    [20030611 Urs Janssen <urs@tin.org>]
  264 
  265 o  add xxencode (<http://www.ctan.org/tex-archive/tools/xxcode/xxdecode.c>),
  266    base224 (<http://b-news.sf.net/>), xBin <http://www.xbin.org/> and
  267    yenc (hide/decode-)support (see <http://nerv.cx/liyang/software/yydecode/>
  268    for readable code, ignore the crap on <http://www.yenc.org/>). also
  269    check <http://www.exit109.com/~jeremy/news/binaries/> which might
  270    replace yenc etc.pp. some day.
  271    [20020216 Urs Janssen <urs@tin.org>]
  272 
  273 o  add "Face:" (incompatible "X-Face:"-replacement) support?
  274    [20040107 Urs Janssen <urs@tin.org>]
  275 
  276 o  turn CA_ERROR_SPACE_IN_NEWSGROUPS, CA_ERROR_NEWLINE_IN_NEWSGROUPS,
  277    CA_ERROR_SPACE_IN_FOLLOWUP_TO, CA_ERROR_NEWLINE_IN_FOLLOWUP_TO into
  278    CA_WARNING_s (see draft-ietf-usefor-article-06.txt 5.5) and mark them
  279    for removal in the future.
  280    [define FOLLOW_USEFOR_DRAFT to turn the mentioned errors into
  281     warnings. 20011226 Urs Janssen <urs@tin.org>]
  282 
  283 o  check FOLLOW_USEFOR_DRAFT code against RFC 5536
  284    [20120221 Urs Janssen <urs@tin.org>]
  285 
  286 o  support "Suggested Minimal Digest Format"
  287    <ftp://rtfm.mit.edu/pub/usenet/news.answers/faqs/minimal-digest-format>
  288 
  289 o  add new threading method: thread by reference, but split threads on
  290    subject change
  291    [Urs Janssen <urs@tin.org>]
  292 
  293 o  rewrite thread-method selection that users can easily combine different
  294    threading methods (THREAD_SUBJ + THREAD_MULTI || THREAD_REFS +
  295    THREAD_MULTI || ...) - see also note in art.c
  296    [20011117 Urs Janssen <urs@tin.org>]
  297 
  298 o  add counter to post-processing commands (processing file x of y)
  299    (Is post-processing really that slow? [Jason Faultless
  300    <jason@altarstone.com>] no but if you post-process more than a
  301    handful of files it would be useful [Urs Janssen <urs@tin.org>])
  302 
  303 o  add key to toggle article and thread sorting preferences on the fly
  304    (like 'u' for threading)
  305 
  306 o  check if servers high mark is lower than the one in users newsrc, if so
  307    issue a warning and allow the luser to reset the highmark in the newsrc
  308    to the servers 'l'ow or the servers 'h'igh mark or 'i'gnore it.
  309 
  310 o  check if the articles Subject/From in the pager matches (minus
  311    whitespaces) the one on the overview file (if available) - if not
  312    issue a warning that the servers overviews seem to be broken. trust
  313    the headers, not overviews. (see note in rfc2046.c)
  314    do the same with the article numbers in the (cached) overview
  315    data (we already do this, but currently this will lead to article "loss").
  316    if they are higher than the server's high-mark don't trust them (and
  317    discard the locally cached data).
  318 
  319 o  attributes (still) needs some work; See doc/config-anomalies.
  320    [20030303 Dirk Nimmich <nimmich@muenster.de>]
  321 
  322 o  add IPv6 support
  323    (add protocol independent wrappers which use IPv6 (functions)
  324     whenever possible).
  325    there are two small problems with the minimalistic IPv6 support which is
  326    currently in tin: when getaddrinfo() is used to get the name/ip of the
  327    newsserver it always uses DNS (gethostbyname()/gethostbyaddr() checked
  328    /etc/hosts first) and getaddrinfo() seems to have a (huge) delay in some
  329    cases. use getipnodebyname()/getipnodebyaddr() (if available) instead.
  330    check for gethostbyaddr_r()/gethostbyname_r() and use them instead
  331    of gethostbyaddr()/gethostbyname() if available.
  332 
  333 o  add cmd-line/tinrc-switch to fetch only headers of unread articles;
  334    in that case, make 'r' reading the rest of the articles
  335    [-G is a start]
  336    allow setting a per group limit via attributes
  337 
  338 o  check if server supports 'LIST MODERATORS' and/or 'LIST DISTRIB.PATS' and
  339    if it does parse the output so it can be shown to the user. (e.g. when
  340    posting to a moderated group, show the moderators mail-address, but still
  341    leave the mailing to the server; if the group has limited distribution
  342    inform the user, ...)
  343 
  344 o  if using "-n" commandline switch you can't subscribe to newsgroups not
  345    present in your newsrc - a simple check against the server
  346    (e.g. GROUP $newsgroup or if !NNTP try to stat the dir) would help.
  347    if the server understands "LIST ACTIVE grp" we could also get the group's
  348    attribute (moderated, etc.) and with "LIST NEWSGROUPS grp" it's
  349    description.
  350 
  351 o  item_by_item_etiquette_warnings [compile-time?]
  352    (e.g. enable x-posts without f'up warning, disable long-sig warning)
  353 
  354 o  don't prefix posted_articles_file with maildir if posted_articles_file
  355    has an absolute path (after expanding ~).
  356    [20130627 Urs Janssen <urs@tin.org>]
  357 
  358 o  posted_articles_file is not available in attributes
  359    [20130628 Urs Janssen <urs@tin.org>]
  360 
  361 o  unify Fcc and posted_articles_file
  362    [20031012 Dirk Nimmich <nimmich@muenster.de>]
  363 
  364 o  MIME-pgp support according to RFC 2015, RFC 3156 - (should be easy now)
  365    and/or in the format that used by signcontrol/pgpverify (see also
  366    tinews.pl)
  367    As MIME-pgp verification needs the undecoded mime-part with its headers
  368    storing the raw-offset of each part in the article would be very helpful.
  369 
  370 o  pgpverify invocation with a single key instead of '|''a''pgpverify' or a
  371    buildin pgpverify solution.
  372 
  373 o  pgp-{6,7} support
  374 
  375 o  add check for GPGME (<http://www.gnupg.org/related_software/gpgme/>) and if
  376    found use it for pgp actions.
  377 
  378 o  add feature Cc:
  379 
  380 o  add feature show_new_newsgroups_since
  381 
  382 o  add new key which tags articles based on a prompted regex, could be used
  383    for GROUP_MARK_THREAD_READ,PAGE_MARK_THREAD_READ,THREAD_MARK_ARTICLE_READ
  384    and/or something like GROUP_SELECT_THREAD/THREAD_SELECT_ARTICLE which
  385    works on tagged arts (the later might be useful in conjunction with
  386    GROUP_MARK_UNSELECTED_ARTICLES_READ)
  387    [20051110 Urs Janssen <urs@tin.org>]
  388 
  389 o  Additions to the thread menu:
  390      ']'  (GLOBAL_QUICK_FILTER_KILL)
  391      '['  (GLOBAL_QUICK_FILTER_SELECT)
  392      'r'  (reply to) /* not 'R' cause it conflicts with mail_bugreport */
  393      ''   r should be toggle show all/show only unread

  407      'e'  (edit mailgroup article)
  408      keys to go to previous/next thread
  409 
  410 o  Additions to the group menu:
  411      'V'  (View/pipe/save multimedia attachments)
  412      'Y'  (check for new articles in group)
  413      '%'  (toggle rot13 encoding of screen content)
  414 
  415 o  Additions to the select menu:
  416      '%'  (toggle rot13 encoding of screen content)
  417      key to toggle groupname abbreviation
  418 
  419 o  Add to the 'M'enu:
  420      'R'  (GLOBAL_BUGREPORT)
  421      '&'  (GLOBAL_TOGGLE_COLOR)
  422      and maybe a way to change built in path like DEFAULT_MAILER, PATH_PGP, ...
  423 
  424 o  Add to the attachment menu ('V'):
  425      'F'  post followup to current article, not including current attachment
  426      'R'  reply through mail to author, not including current attachment
  427           or

  430           attachment(s)
  431      'm'  mail attachment
  432      'o'  print attachment
  433      'r'  reply through mail to author, including current attachment
  434      't'  tag attachments for '|', 'p', 's', 'm' (done for 's')
  435      '#'  tag range of attachments (n-m)
  436      'x'  repost current attachment to another group
  437      '%'  (toggle rot13 encoding of screen content)
  438      '&'  (GLOBAL_TOGGLE_COLOR)
  439 
  440 o  Add a commandline switch (-V) that prints out all values of cpp-symbols
  441    etc. [partly done, but should be cleaned up]
  442 
  443 o  Reorganize tinrc into related sections for easier editing
  444    e.g., Display, Posting etc.
  445 
  446 o  A system-wide tinrc configuration file (to hold some defaults).
  447    [done: /etc/tin/tinrc] A key code to reset to the system defaults.
  448    Maybe a second file which could be used to force settings (eg
  449    inews & mailer) (tin.defaults [--with-defaults-dir] is a start)
  450 
  451 o  when From: only contains "First-name Last-name" tin strips the
  452    Last-name in group/thread/page-level
  453    [20020319 Urs Janssen <urs@tin.org>]
  454 
  455 o  Bounce duplicate Message-ID's when the headers are read. This will
  456    make the threading code happier too.
  457    Make read_overview() more forgiving of errors. If the article # is okay,
  458    then there is no reason to completely hide the article
  459    [Jason Faultless <jason@altarstone.com>]
  460 
  461 o  Merge the selection code with the range code. Having two similar methods
  462    of picking articles with similar goals is wasteful.
  463    [Jason Faultless <jason@altarstone.com>]
  464 
  465 o  add check for liblzma/libbzip2/zlib (>=1.1.4)/[mini]lzo, lzlib, liblz4,
  466    liblrzip, libzstd, ...
  467    (<http://tukaani.org/xz/>, <http://sources.redhat.com/bzip2/>,

  470     <http://freecode.com/projects/long-range-zip>,
  471     <https://github.com/facebook/zstd>) and add an option to
  472    write/read *zipped local overviews.
  473    the libs might also be used for post-processing articles.
  474 
  475 o  rewrite/cleanup all the debugging code, the output in /tmp is messy; the
  476    on screen output either slows down things dramatically or is unreadable;
  477    split DEBUG_MISC?
  478    [Urs Janssen <urs@tin.org>]
  479 
  480 o  replace gettimeofday() with clock_gettime() if available in parsdate.y
  481    as POSIX.1-2008 marks gettimeofday() as obsolete.
  482    [20110910 Urs Janssen <urs@tin.org>]
  483 
  484 o  Add 'M'enu option to define chars for utf8_graphics.
  485 
  486 Posting enhancements
  487 --------------------
  488 o  sort Followup-To:/Newsgroups: after stripping doubled newsgroups and
  489    before checking if they are identical, if so, strip Followup-To: and
  490    use unsorted but stripped Newsgroups:-line only
  491    ulBuildArgv() would be good for this
  492 
  493 o  if Newsgroups:-line has groups in it which are not present in the users
  494    active file ask the user if he wants to strip these groups from the
  495    newsgroups-line (N/y)
  496    do the same for Followup-To:
  497 
  498 o  check if any valid groups are in the Followup-To:-line and if not inform
  499    the user and use Newsgroups: instead (at the start of post_response())
  500 
  501 o  bring up a warning on a long Newsgroups: (>=5) line and
  502    force the user to confirm every single group he wants to post (or
  503    redirect followups to) in. (N/y)
  504 
  505 o  bring up a warning when trying to f'up into a binary group
  506    (use a regexp to detect binary groups e.g.:
  507     (?:\.binae?r|de\.alt\.dateien\.))
  508    (Warning, sending a followup to a binary group is undesired, post it
  509     anyway? N/y)
  510    [Urs Janssen <urs@tin.org>]
  511 
  512 o  posting to a binary group should warn if no followup is set to another
  513    group/poster (you have not set a target for a possible discussion on your
  514    post, would you like to go on anyway? N/y)
  515    [Urs Janssen <urs@tin.org>]
  516 
  517 o  when posting to a group containing uppercase-letters: bring up a
  518    warning: "Newsgroup-names should be all lowercase, correct it? (Y/n)"
  519 
  520 o  Enhance -n to take newsgroup name as argument and use group_get_art_info()
  521    to allow posting to groups other than those in newsrc.
  522 
  523 o  add config option for (external) viewer to show postings stored in
  524    keep_posted_articles_file
  525    [20021003 Michael Gerhards <HM-Gerhards@uni.de>]
  526 
  527 Filtering enhancements
  528 ----------------------
  529 o  add xref filter to the filter-menu
  530 
  531 o  add spamassassin interface when ever adding body filters
  532 
  533 o  add used filter-type to filter file or filter rule or use different
  534    filter files for wildmat/regexp
  535 
  536 o  add command: mark all articles older/newer than <date> (or <days>) as
  537    read (useful when subscribing to a new group with high-traffic...)
  538 
  539 o  fix kill/hot mechanism so that it is possible to match articles on
  540    arbitrary headers
  541 
  542 o  don't strip "Re: " out of the subject before applying the filter on it
  543 
  544 o  allow any given amount of days in default_filter_days not only
  545    {1, 2, 4} * 28 days
  546 
  547 o  allow expiring filter entries n-days after the last time they matched
  548 
  549 o  add command to generate filter rules for all currently tagged articles
  550 
  551 o  allow editing of the strings presented in the kill-Menu for
  552    "Kill Subject", "Kill From", "Kill Msg-Id" without having to edit
  553    the full filter-file
  554    [20120201 Urs Janssen <urs@tin.org>]
  555 
  556 o  allow to abort the filter loop with iKeyAbort when entering a (large)
  557    group
  558    [20160211 Urs Janssen <urs@tin.org>]
  559 
  560 Pager enhancements
  561 ------------------
  562 o  add 'autoview' (spawn external viewer) 'autohide' (don't even show info
  563    about that part) for different content-types
  564 
  565 o  integrate multi-part tagging with regular tagging, eg.
  566    "This article appears to have multi-parts, try and find them (y/n)?"
  567 
  568 o  add Content-Language (RFC 3282) analysis
  569 
  570 o  suppress hide_uue=2 checking unless first line in an article or following
  571    a blank line
  572 
  573 o  add missing mailcap (RFC 1524) features (%n, %F, copiousoutput, print, ...)
  574    [20111205 Urs Janssen <urs@tin.org>]
  575 
  576 Internal Changes
  577 ----------------
  578 o  in ENABLE_NLS case replace PLURAL() macro with proper use of
  579    ngettext(3) (if found by configure) to support languages with
  580    more than one plural form.
  581    [20150113 Urs Janssen <urs@tin.org>]
  582 
  583 o  rename disable_gnksa_domain_check to enable_gnksa_domain_check and
  584    invert logic now the default changed
  585    [20131119 Urs Janssen <urs@tin.org>]
  586 
  587 o  %s/%S in quote_char should replaced by %I in misc.c:copy_body() and
  588    config.c:rc_update() to be consistent.
  589    [20131003 Urs Janssen <urs@tin.org>]
  590 
  591 o  curses.c:input_pending() and curses.c:get_arrow_key() have
  592    #ifdef HAVE_SELECT and a code path for the case when we don't have
  593    select(2), but read.c:wait_for_input() has no code path for the
  594    !HAVE_SELECT case. we should add a !HAVE_SELECT case there (or at
  595    least have adjusted messages in txt_reading_article and txt_group)
  596    [20110506 Urs Janssen <urs@tin.org>]
  597 
  598 o  ditch MAX_MSG_HEADERS (post.c)
  599    [20110212 Urs Janssen <urs@tin.org>]
  600 
  601 o  always display (also) the servers error response string to the user,
  602    currently tin sometimes gives generic messages (e.g. when authentication
  603    fails), but the servers response may include additional infos (like
  604    bandwidth exceeded)
  605    [20101230 Urs Janssen <urs@tin.org>]
  606 
  607 o  rewrite mini-help, remove the long strings and generate them dynamiclly
  608    one help text for each key makes translations more easy and uniq and can
  609    use the available space on the screen much better if not running on 80
  610    columns.
  611    [20100326 Urs Janssen <urs@tin.org>]
  612 
  613 o  rewrite auth.c
  614    - turn t_bool authinfo_user, authinfo_sasl, authinfo_state into
  615      enum authinfo { NONE = 0, USER = 1, SASL = 2 }
  616 
  617 o  fix aclocal.m4:CF_FUNC_SYSTEM and/or misc.c:invoke_cmd() that
  618    --enable-broken-system-fix/IGNORE_SYSTEM_STATUS isn't needed anymore.
  619    [20090520 Urs Janssen <urs@tin.org>]
  620 
  621 o  tinrc.confirm_choice should be written/read as int, not string as users
  622    who edit the tinrc manually can't know the exact strings required.
  623    unfortunately rc_update() can't handle type changes (rc_update should
  624    also get the split version number as arg so we can do specific
  625    changes).
  626    [20081112 Urs Janssen <urs@tin.org>]
  627 
  628 o  use read()/write() instead of fputs()/fgets() on socket
  629 
  630 o  move several (server related) files into the per-server dir
  631    e.g.:
  632       ${TIN_INDEX_NEWSDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}/.news${NNTPSERVER+"-$NNTPSERVER"}/
  633    should be
  634       ${TIN_INDEX_NEWSDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}${NNTPSERVER+"/$NNTPSERVER"}/.news/
  635    [20050807 Urs Janssen <urs@tin.org>]
  636 
  637 o  upgrade configure-script to >= autoconf-2.61
  638    [20050728 Urs Janssen <urs@tin.org>]
  639 
  640 o  remove untranslatable constructs like txt_prefix_*
  641    [20050413 Urs Janssen <urs@tin.org>]
  642 
  643 o  keys which could be renamed/merged:
  644    - 'l' GroupListThd, PageListThd
  645    - 'm' GroupMail, PageMail, PostMail, ThreadMail
  646    - 'D' GroupCancel, PageCancel, ThreadCancel
  647    - 'N' GroupNextUnreadArt, PageNextUnreadArt, (SelectNextUnreadGrp)
  648    - 'S' GroupAutoSave, PageAutoSave, ThreadAutoSave
  649    - 'P' GroupPrevUnreadArt, PagePrevUnreadArt
  650    - '@' GroupReverseSel, ThreadReverseSel
  651    - '~' GroupUndoSel, ThreadUndoSel
  652    [20050408 Urs Janssen <urs@tin.org>]
  653 
  654 o  read_overview() calls eat_re() which strips the "Re: " out of the
  655    subject. the modified subject is used for batch_mode opperatios (-N/-M)
  656    which might not be what ppl. expect and eat_re() is the only function
  657    which needs the 'regex' overhead in batch_mode... (see also the note
  658    about "Re: "strpping at "Filtering enhancements").
  659    [20050225 Urs Janssen <urs@tin.org>]
  660 
  661 o  use new_nntp_command() instead of nntp_command() in the rest of the
  662    code (where useful; if we do a global change, rename it to
  663    nntp_command()). see check_extensions() for a sample usage.
  664    [20050211 Urs Janssen <urs@tin.org>]
  665 
  666 o  replace various occurrence of "US-ASCII" by DEFAULT(_MIME)_CHARSET
  667    and define that to "US-ASCII" (to make 'updates' easier).
  668    [20040929 Urs Janssen <urs@tin.org>]
  669 
  670 o  get rid of CURR_GROUP, use t_group instead
  671    create a global t_group *CURR_GROUP instead of the current macro
  672    reduce dependencies on my_group[] & selmenu outside of select.c
  673    [20030501 Urs Janssen <urs@tin.org>]
  674 
  675 o  clean up $AUTOSUBSCRIBE code (the NNTP code path is a mess)
  676    [20030412 Urs Janssen <urs@tin.org>]
  677 
  678 o  check where joinpath() should be used (e.g. grep for TMPDIR in the source)
  679    [Urs Janssen <urs@tin.org>]
  680 
  681 o  make configure look for strrstr() in libpub & publib.h
  682    [Urs Janssen <urs@tin.org>]
  683 
  684 o  reorder several structs to avoid padding (see gcc -Wpadded)
  685    [Urs Janssen <urs@tin.org>]
  686 
  687 o  what type is base[]? (long, see memory.c:init_alloc()~102)
  688    There is a lot of confusion internally over how it is used
  689    compare setup_hard_base() with find_base() etc..
  690    [Jason Faultless <jason@altarstone.com>]
  691 
  692 o  check where PRODUCT should be used instead of tin_progname and/or "tin"
  693    [Urs Janssen <urs@tin.org>]
  694 
  695 o  check where NEWSRC_FILE should be used in lang.c instead of "newsrc"
  696 
  697 o  kick Hungarian notation
  698    [Urs Janssen <urs@tin.org>]
  699 
  700 o  check where iKeyAbort should be used instead of ESC (etc.pp.)
  701    (AFAICS all fixed except prompt.c and read.c/'z')
  702    [Urs Janssen <urs@tin.org>]
  703 
  704 o  close potential security holes:
  705    - remove fixed length buffers (find_nov_file(), print_from(),
  706      quote_space_to_dash(), escape_shell_meta(), backup_article(),
  707      build_messageid(), get_secret(), get_host_name(), get_domain_name(),
  708      get_fqdn(), get_user_name(), get_full_name(), build_sender(), ...)
  709    - change all system()/popen() calls to fork() and exec() calls
  710    - check where we should use snprintf() instead of sprintf()
  711    - check where we should use strncat() instead of strcat()
  712    - check where we should use strncpy() instead of strcpy()
  713    - check possible races with access()/link()/rename()/stat()/
  714                                unlink()/chdir()/fopen()/fstat()/open()/
  715                                opendir()/t_open()/tmpfile()
  716    - check getenv() results before using it
  717    - check where my_strncpy() or STRCPY() should be used
  718    [Urs Janssen <urs@tin.org>]
  719 
  720 o  add to autoconf:
  721    - eradicate platform/compiler ifdefs
  722 
  723 o  clean up architecture independent files, rename several defines,
  724    remove useless doubled defines
  725 
  726 o  split tin.h/proto.h for better dependencies in Makefile
  727 
  728 o  check where int/long/... should be replaced by size_t, uid_t, mode_t,
  729    off_t, ...
  730    [Urs Janssen <urs@tin.org>]
  731 
  732 o  add check for sizeof char, short, int, long, ...
  733    make sure that the code works even with 'uncommon' values
  734    (e.g. char = 1 byte with 32 bit)
  735 
  736 o  cleanup post.c
  737 
  738 o  check code with Splint (LCLint) <http://www.splint.org/>,

  745    (<http://caca.zoy.org/wiki/zzuf>)
  746 
  747 o  rewrite the tag code so that arts[].tagged becomes index in arts[]
  748    of next tagged article. num_of_tagged_arts becomes index of first
  749    tagged art. Traversing tagged arts becomes much easier & faster.

  752 o  strip Xref:-header if saving news in batch mode (-S)?
  753    [Urs Janssen <urs@tin.org>]
  754 
  755 o  what is with NEW_HASH_METHOD in list.c?

  757 o  rewrite code to use INEWS_PATH instead of INEWSDIR
  758    [20021007 Urs Janssen <urs@tin.org>
  759 
  760 o  remove built in path of external commands (metamail, ispell, ...)

  773 Unicode
  774 -------
  775 o  add UTF-8 (unicode) support (RFC 2279)
  776    (see <http://www.cl.cam.ac.uk/~mgk25/unicode.html>)
  777    if we ever want to add UTF-7 (RFC 2152) (posting) support (I don't
  778    think this is needed) we have to encode it ourself (as iconv()
  779    might encode <, @, > which leads to illegal headers) or split
  780    headers into "encoding part" and "rest" ...
  781    [local_charset <-> UTF-8 which needs iconv() is added;
  782     20010830 urs@tin.org]
  783 
  784 o  make select/group/thread/page-level multibyte "safe". they all use
  785    strlen(), strncpy(), strncat(), snprintf() to build the screen - but
  786    in a multibyte environment (e.g. mm_local_charset=UTF-8) this is a
  787    fault. [mostly done for ncursesw]
  788 
  789 o  make mm_network_charset an "option_list" to avoid junk input or
  790    undesired (UTF-1, UTF-7, UTF-16*, UTF-32*, UCS-2, UCS-4, ...) encodings.
  791    add configure check for the hardcoded charsets (try iconv_open(x,
  792    us-ascii) on each...) and disable those not available.
  793    (think about more network charsets (GB2312, GB18030, Shift_JIS,
  794     ISO-8859-6[-{I,E}], ISO-8859-8[-{I,E}], ISO-8859-11, VISCII, VIQR;

  800     "US-ASCII:ISO 8859-5:KOI8-R:UTF-8",
  801     "EUC-CN:ISO-2022-CN:ISO-2022-CN-EXT:Big5:UTF-8", whatever)

  883 
  884 o  sometimes we convert the supplied server name to lowercaes (for cached
  885    overviews) and sometimes we don't (nrctbl.c code and -g arg). Thus
  886    -g Foo.bAr.eXample may result in file not found
  887    for entries like '*       ~/.tin/.newsrcs/${NNTPSERVER-localhost}'
  888    even there is a ~/.tin/.newsrcs/foo.bar.example file.
  889    Should we always lowercase $NNTPSERVER / -g? (but still allow

  904    overviews, is this desired?
  905    [20151112 Urs Janssen <urs@tin.org>]
  906

  908    on Message-IDs, but they might show up in mailgroups - assign a pseudo
  909    Message-ID to them?

  914    "No permissions to go into /home/$USER/.tin/${NNTPSERVER}"

  927 
  928 o  what about !us-ascii chars in username/password when using
  929    AUTHINFO USER/PASS? Currently they are sent as is, RFC 3977 says
  930    "The character set for all NNTP commands is UTF-8", RFC 4643 doesn't
  931    mention any special handling.

  941 
  942 o  add "COMPRESS DEFLATE" support? this would require a
  943    rewrite of the code which reads data from the network (which should be
  944    done anyway for TLS) as we must handle null-bytes in the stream.

  947 
  948 o  the documentation suggests that novrootdir/$TIN_NOVROOTDIR defaults to
  949    spooldir/$TIN_SPOOLDIR if unset, which is not exactly what happens as
  950    this default is set at configure/compile time, not at runtime, so
  951    setting $TIN_SPOOLDIR to something different than the default will not
  952    automatically adjust $TIN_NOVROOTDIR at runtime. we should either
  953    fix the documentation or the behaviour.

  962 o  replace wildmat.c with uwildmat.c

  974 
  975 o  what about REDIRECT_OUTPUT? shouldn't we better add this to DEFAULT_PRINTER
  976    so ppl. can override it via the 'M'enu? and shouldn't DEFAULT_PRINTER be
  977    detected via configure?
  978    [20080625 Urs Janssen <urs@tin.org>]
  979 
  980 o  create debug output in
  981    ${TIN_HOMEDIR-"$HOME"}/.tin"}${NNTPSERVER+"/$NNTPSERVER"}
  982    instead of in $TMPDIR (as it may contain username and password,
  983    access restrictions in $TMPDIR are a bad idea as other users
  984    need to be able to overwrite the file)
  985    [20080211 Urs Janssen <urs@tin.org>]
  986 
  987 o  -M/-N report is mailed to userid, should we use tinrc.mail_address
  988    instead?
  989 
  990 o  tin uses the first sig-isolator as recent one, USEFOR says it should
  991    use the last. There is no consensus that tin should follow this USEFOR
  992    requirement.
  993 
  994 o  'K' is still a bit inconsistent:
  995    - in the group and thread menu it marks current item read & jumps to the
  996      next unread item.
  997    - in the article pager (page.c) it marks the rest of the current thread
  998      read and jumps to the next unread article. should we let 'K' behave
  999      like <TAB> in the pager?
 1000 
 1001 o  rename prompt_followupto (to prompt_extra_headres) and make it an option
 1002    list like {"Followup-To"; "Summary"; "Keywords";
 1003    "Followup-To & Summary"; "Followup-To & Keywords";
 1004    "Summary & Keywords"; "Followup-To, Summary & Keywords"} or make it a
 1005    user-definable text field like news_headers_to_display? or leave this
 1006    entirely to the user - he could tweak attributes accrodingly.

 1011      with "PostPost	p	y	w" in keymaps)
 1012    should we try to show them all?

 1026 
 1027 o  trn and perls Net::NNTP::Auth use ~/.nntpauth (format is
 1028    "^server\s+user\s+password"), shall we also try ~/.nntpauth if we can't
 1029    find a matching entry in ~/.newsauth? and should we look for
 1030    ${TIN_HOMEDIR:-"$HOME"}/.tin/.newsauth if ~/.newsauth is not found?
 1031    [20040128 Urs Janssen <urs@tin.org>]
 1032 
 1033 o  allow a different port on newsauth and or newsrctable (server:port [...])?

 1036 
 1037 o  what todo if in a CTE: x-uue the CD: filename differs from the one given
 1038    in the begin line? IMHO we should use the one from the begin line for
 1039    saving and in the overview in the pager.
 1040    [urs@tin.org]
 1041 
 1042 o  inverse_okay's Menu description isn't accurate (invers is also used for
 1043    URL highlighting). mono_mark* do allow "Reverse video" even if
 1044    inverse_okay=FALSE.
 1045 
 1046 o  --disable-inverse-video seems to be ignored - do we still need it?

 1049    (if so, also move last_search there)
 1050    [Jason Faultless]
 1051
