35 NOTES, ChangeLog (packager-affine)
36 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
38 - We now support IMAP internationalized names, to be "simulated" via the
39 new user command `imapcodec'#135|#_135:
41 ?0[tmail ]? imapc enc Trübe/Wölkchen
42 in: Trübe/Wölkchen (16 bytes)
43 out: Tr&APw-be/W&APY-lkchen (22 bytes)
44 ?0[tmail ]? imapcodec decode Tr&APw-be/W&APY-lkchen
45 in: Tr&APw-be/W&APY-lkchen (22 bytes)
46 out: Trübe/Wölkchen (16 bytes)
47 ?0[tmail ]? copy 1 +Trübe/Wölkchen
48 "imap://user1@localhost/Trübe/Wölkchen" [New file] 6850 bytes
50 Those who were used to get around the missing support by using
51 readily-encoded names have to update their resources because passing
52 in such a name will result in re-encoding. [Quite a lot, see below]
54 - The special handling of *folder*#382|#376 for IMAP boxes has been
55 deprecated after introduction of the new *inbox*#396|#_396 variable,
56 which will henceforth be regulary used for expansions of "%"
57 filenames. If it is set to the empty string then _only_ that
58 special-casing of *folder* is bypassed, and the usual $MAIL /
59 compile-time mailspool search is applied. [c220e90,a324bf3]
60 (Stephen Isard, Jürgen Daubert)
62 - Cyrus IMAP servers with their dot hierarchy delimiter should now be
63 supported. The variable *imap-delim*#393|#_393 (and [-USER]@HOST
64 variants) will be used to normalize if set, otherwise the first seen
65 possible delimiter is used. [a65afca,9e23878,21568f8]
66 (Stephen Isard, Jürgen Daubert)
68 ?0[tmail ]? Fi+Trübe.............Wölkchen
69 IMAP error: Mailbox doesn't exist: Trübe.Wölkchen (0.000 + 0.000 secs).
70 #ERR#?1[tmail +Trübe.Wölkchen]? set imap-delim-user1@localhost=/.
71 Oh. Mailbox changed. Not before v15, sorry.
72 ?0[tmail +Trübe.Wölkchen]? Fi+Trübe.............Wölkchen
73 "+Trübe/Wölkchen": 1 message [Read only]
74 ?0[tmail +Trübe.Wölkchen]? unset imap-delim-user1@localhost
75 ?0[tmail +Trübe.Wölkchen]? Fi+Trübe/.............Wölkchen
76 "+Trübe/Wölkchen": 1 message [Read only]

82 1657626 Simplify *folder* (implicit trail solidus) (Stephen Isard, Ralph
84 7a09af6 `write'++: !interactive: urlxenc() attachment paths (Ralph Corderoy)..
86 If non-interactive batch mode would be commonly in use i would claim
87 this to be a security fix, but not yet.. If messages are `write'n out
88 in non-interactive mode then it is now ensured that attachments end in
89 the current directory, that they don't overwrite yet existing files, and
90 that shell pipes won't be executed (after the now applied name
91 conversion the pipe command ends up as a normal filename).
93 c220e90 Add *inbox* (Stephen Isard, and Jürgen Daubert)..
94 a65afca Add *imap-delim{,-{{,USER@}HOST}}* (Stephen Isard, Jürgen Daubert)
95 8f0f225 IMAP: [a65afca] (Add *imap-delim{,-{{,USER@}HOST}}*) for real now
99 ba4f26f n_utf32_to_utf8(): fix upper limit (should be 0x10FFFF)

113 830f948 IMAP: add support for international mailbox names..
114 d015c46 IMAP: fix and tweak previous [830f948]

127 Ts, ts, looks like Freud had his Freude interpreting this staggering.
128 But should be correct and working now.
133 The complete changelog of commits in between two versions can be
134 inspected by using the git(1) `log' command as shown below, where "OLD"
135 and "NEW" are the two versions to be compared.
138 $ git log --reverse --topo-order --abbrev-commit OLD..NEW
139 # Only topic branch headers (--no-merges for content commits only):
140 $ git log --oneline --reverse --topo-order --merges OLD..NEW
141 # Same, but truly accessible:
142 $ git log --oneline --reverse --topo-order --merges --parents OLD..NEW |
143 while read c1 c2 c3 c4 c5 c6; do
144 printf "%-24s: \$ git log --oneline --no-merges ${c1} ^${c2}\n" "${c6}";

162 ------------------------------------------------------------------
164 A cumulated bugfix release.
165 It also brings in some corrections to no-brainers of the past.

177 NOTES, ChangeLog (packager-affine)
178 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
180 - The repository layout has been changed / extended!
181 Please see README on interest.
183 git(1) shortlog (edited)
184 ^^^^^^^^^^^^^^^^^^^^^^^^
186 f01291d extract_date_from_from_(): dig more invalid MBOXes (Antonio Radici)..
187 98050a7 THANKS: Antonio Radici
189 freedesktop.org obfuscates MBOX From_ lines, and S-nail was much too
190 strict for quite some time. This strict behaviour was introduced as
191 part of the fixes which finally allowed roundtripping messages in
192 between different mailbox types, but it didn't really work out.
194 In the future we only warn if we see invalid MBOX files, and will print
195 the invalid lines with *debug* or *verbose* set, but anyway accept what
198 096809e popen.c:_file_save(): FIX false cherry-pick [41250b1] for IMAP..
200 v14.8.10 couldn't do "copy * IMAP-SPEC" due to this.
202 788aad0 url_parse(): better take better care for path parts (Stephen Isard)..
203 fb32f8f IMAP: honour readonly via -R, not only via `File' (Stephen Isard)
207 bd6090d sendout.c: fix HAVE_DEBUG From_ quoting..
208 e716a9c Many: drop support for *mbox-rfc4155* - a no-brainer..
210 More on MBOX, as above.
212 603a3dd sendmp(), setfile(): FIX: ensure time_current is actualized
214 Oh! Yes, there were actually two code paths which suffered a lot from
215 the "optimize date and time systemcalls" from years ago! Now fixed. ._.
217 63e7ade is_head(): change compat argument to check_rfc4155..
219 More on MBOX, as above.
221 c5b40e4 okeys.h: regenerate (Apologies: Stephen Isard)
225 3838ffd setptr(): tweak [63e7ade], log more invalid From_'s if verbose
227 More on MBOX, as above.
229 2eb6ca1 mime_types.c:_mt_by_filename(): basename() path (fix/tweak relative
231 b9599b0 make.rc, mk-conf.sh: WANT_DEVEL includes WANT_DEBUG, but not vice
233 ec81a41 cmd_tab.h: allow history for `set', `setenv', `varshow'
235 Much better to see them in the `history'.
237 a715162 Add a RFC 6068 url_mailto_to_address() hack for List-Post:
239 We will now strip off any hfield additions after a "?", and we will
240 perform URL percent decoding before using the value given.
241 (Is only used for "automatic mailing-list detection".)
243 e774dfb imap.c: do not hard error out if FEDIT_SYSBOX|FEDIT_NEWMAIL
244 39a7571 FIX "," message specification (since [1c4b8c9], v14.8.4)..
246 Yes, you can say "f," again, and it should find the parent message.
248 171f111 FIX [44cec1f] (Fix "address" message specifications (John Dodson))..
250 Sorry, Mr. John Dodson of Australia. They now really work as
251 standardized with our extensions, and there is nothing anyone can do
254 256da01 *folder*: IMAP: add /INBOX when there is a trailing slash (Stephen
256 2afd5c8 Previous, IMAP now for much better (Stephen Isard)
257 e5eb5fe Fix + expansion for IMAP, broken since [edb2dcd], 2013-06!!
258 ce40a87 imap.c: do not print update message on readonly boxes
259 52fcb7e Oops, restore proper *folder* behaviour for non-IMAP
260 111f80a FixFix IMAP "+" expansion and more (Predrag Punosevac)
262 More IMAP fixes. Should really work now as good as never before.
264 v14.8.10 ("Anachalcos"), 2016-08-20
265 -----------------------------------
267 A cumulated bugfix release.
268 And because v14.9 still takes time.
272 Apologies to Sergey and those members of the Roff community which would
273 like to see progress!
275 S-nail will become S-mailx after v14.9, and all project resources
276 will move to www.sdaoden.eu with v14.9; only the ML remains hosted
277 at Sourceforge.net as of this writing.
278 We thank Sourceforge.net for hosting this project so many years!
283 Yes, "quick and dirty" only for Anachalcos.
285 7f7bae1 Fix `z' (Tim)
287 Fixes page-wise movement if the argument is greater than 9.
289 43ad441 THANKS: update mail address of Tim (trondd)
290 8b85b96 Fix compiler warning of [7f7bae1] (Fix `z' (Tim))
291 6afff81 FIX possible intwrap caused delays (for mailboxes with size == 1)
292 530e81f FIX n_utf8_to_utf32() sequence length checks (since [558d8b8],
294 78083c0 HTML filter: filter out some characters
295 407a705 Actively filter out U+00AD characters (Vincent Lefevre)..
296 e5591f2 THANKS: Vincent Lefevre
297 5c458cc FIX MBOX append (since ever (nail 11.16, 2004-11-18])!)..
299 This only fixes invalid non-empty MBOX mailboxes, so "FIX" is possibly
302 75982b9 bidi_info_needed(): no variation selectors etc. -- CText, where are
304 e65db06 FIX n_verr(): cannot reuse va_list..
306 Only for error messages > ~2 KB, which we usually don't produce.
308 23e8697 Fix *quote-fold* (on GNU/Linux iswspace() does not return boolean!)
309 98cf903 FIX: really_rewind() for pre POSIX Issue 7
311 Hardly affects anyone, i had to look into old v5 FreeBSD: maybe.
313 41250b1 FIX: no O_APPEND for .bz2/.xz/*file-hook-load*! Use lseek(2)!!..
315 This is the reason for this release, and applies to all C libraries
316 which optimize fseek(3) and do not adjust the file descriptor via
317 lseek(2) if the resulting offset is in the I/O buffer.
318 It seems to enable me to say
320 set file-hook-load-xz_pgp='gpg -d | xz -dc' \
321 file-hook-save-xz_pgp='xz -zc | gpg -e'
323 on a GNU/Linux system without ending up with corrupted boxes,
324 i.e., a complaining gpg(1) that says that says so.
326 224d858 popen.c:_file_save(): adjust partial [41250b1] cherry-pick
327 87c902a sendmp(): fix possible false insertion of colour reset seq.
329 v14.8.9 ("Dung Beetle"), 2016-06-21
330 -----------------------------------
332 A cumulated bugfix release.
334 Credits Ralph Corderoy.
335 Apologies, Dirk-Wilhelm Peters.

339 at Sourceforge.net as of this writing.
340 We thank Sourceforge.net for hosting this project so many years!
345 - *signature* and tail injections now work correctly even in combination
346 with -t. [d4237ac] (Dirk-Wilhelm Peters)
348 - Fix faulty (by-one) buffer overflow calculation in the NCL line editor
349 that could sometimes be seen when using ^W for backward deleting
350 a word when using this at a freshly created rightmost columns.
351 Bug was introduced in [d33bd89] (tty.c, NCL: reduce realloc counts,
352 2013-08-23). (Ralph Corderoy)
357 b0b974e mk-conf.sh: disable -b for tcc(1) [mob]
358 a415c58 makefile:_update-release: symlinks do not work with lighttpd, use hard
360 2fefb1f collect(): fit ~? output in 25 lines (fixes [5dea8a4,4e61d5c] ;)
361 7c7c888 mime.types: oops, fix x-xz tbz->txz extension!
362 c40c206 collect(): hint for `~.' if *ignoreeof* is set, not ".": needs *dot*
363 d4237ac Fix *signature* / tail injection in conjunction with -t..
364 ef6a9c2 mk-conf.sh: pcc(1) as of CVS works without stack protectors!
365 d5cec10 FIX HTML filter: swallow lone ampersands in parameters (SIGH!)..
366 08eb902 FIX: avoid duplicate output for HTML filter..
367 524adf4 makeprint(): filter some iswprint()==true, but which really aren't..
368 552b2b8 `set': fix quoting when printing all variables
369 aa8df72 mk-conf.sh: fix DEVEL<->DEBUG interdependency; terminate printf(1)
371 f84b0cd mk-conf.sh: check for the needed environ(3)

373 fdcbf59 Again "improve" ~? listing
374 ba29651 FIX: cntrlchar() was broken since [4e49924] from 2012-10-15!!
375 08ab13f tty.c, NCL fix possible off-by-one (Ralph Corderoy)
376 815e99f makefile:_update-release: rm TODO in [timeline] _shipout release_ ball
378 v14.8.8 ("The Vulture 38"), 2016-03-26 (v14.8.7 as of 2016-03-25 broken)
379 ------------------------------------------------------------------------
381 A cumulated bugfix release.
383 Credits Gaetan Bisson, Sergey Matveev, Dirk-Wilhelm Peters, Allan McRae
385 All the mentioned persons deserve special thanks indeed.
387 We welcome Sergey Matveev, Allan McRae and Ralph Corderoy in THANKS.
389 S-nail will become S-mailx after v14.9, and all project resources
390 will move to www.sdaoden.eu with v14.9; only the ML remains hosted
391 at Sourceforge.net as of this writing.
392 We thank Sourceforge.net for hosting this project so many years!
394 NOTES, ChangeLog (packager-affine)
395 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
397 - Thanks to Sergey Matveev the Maildir code is now compatible to *BSD.
398 Interested persons may read the commit log. [0c30b14] (Sergey Matveev)
400 - The (much to restricted) test target should now work if $SHELL is set
401 to something "nologin". [7876f3a] (Gaetan Bisson)
403 - If *sendmail-no-default-arguments* is set we will NOT (!) terminate
404 MTA options with "--", assuming the user does. This allows, e.g.,
405 very sick things like (ouch) [8b0bdbe]
407 set sendmail="/bin/ssh" \
408 sendmail-arguments="steffen@sdaoden.eu /usr/sbin/sendmail -t" \
409 sendmail-no-default-arguments \
410 sendmail-progname="ssh"
415 - The primitive builtin HTML filter should now correctly parse HTML
416 parameters. It seems to become necessary ;) [e227a78,65df701]
418 - *signature* will now undergo MIME encoding. [fe209f7]
419 (Dirk-Wilhelm Peters)
421 - Operating systems without getaddrinfo(3) but only with gethostname(3)
422 should be able to resolve DNS (port numbers) correctly again.
423 [7dd3a71] (Allan McRae)
425 - The builtin NCL no longer counts gabby history limits against the
426 given maximum persistent history size unless gabbiness is desired.
429 - The builtin NCL couldn't paste more than one line since October 2015.
430 [ff5d914] (Ralph Corderoy)
432 ChangeLog (purely technical)
433 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
435 - WANT_READLINE environments should possibly have a better experience
436 hen interactively editing the attachment list. [ede2800]
437 (In general interactive situation has to improve a lot.)
439 - Fix a bit of weird buffer handling. [536d3a7,0f2cc31,e9a5c22]
442 - Fix the fixed buffer handling which broke v14.8.7. [3e4831a]
445 v14.8.6 ("Hen Harrier II"), 2015-12-28
446 --------------------------------------
448 A cumulated bugfix release.
450 Credits Hilko Bengen, Salvatore Bonaccorso, Martin Sebor,
451 Aharon Robbins and Philip Guenther.
453 We welcome all credited persons in THANKS.
455 NOTES, ChangeLog (packager-affine)
456 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
458 - WANT_AMALGAMATION dependency tracking has been fixed.
461 - "INSTALL": clarification: "make" OR "make install", NOT "[make &&]
462 make install". More to come in v14.9. Also INSTALL now says that the
463 default configuration includes all non-experimental features, whereas
464 the otherwise identical CONFIG=MAXIMAL does include them.
467 - SENDMAIL will now fallback to /usr/sbin/sendmail if we don't find any
468 executable sendmail(1). We had some similar issue on ArchLinux, but
469 i failed to deal with the no-sendmail-available case. sendmail(1) is
470 expected in /usr/sbin on *BSD and according to Debian Policy 11.6.
471 [0e09d5e] (Salvatore Bonaccorso)
473 - SYSCONFRC no longer includes SYSCONFDIR. I.e., S-nail now does
474 load(SYSCONFDIR "/" SYSCONFRC);
477 It seems only CRUX-Linux is affected, and i've sent a patch. [807f64e]
479 - We now support the TinyCCompiler. [topic/tcc]
481 - And -- ouch! -- fix S-nail on Solaris, again. It was broken since
482 [3e863c6] (2015-06-23) since necessary linker flags had been
483 overwritten. [fd40d5a,6fe5448]
484 (We also deal with NAME_MAX being the minimum possible now, see below.)
489 - When `Lreply'ing to multiple messages and using the `~:' tilde command
490 the argument list of the `Lreply' itself would have been overwritten,
491 resulting in crashs. [9f5c403 (+ 1162af5,5f08362)]
493 - Temporarily forbid `mbox' but in a system mailbox. I hope v14.9 can
494 perform the action gracefully. [781ee34]
496 - On systems with "unsigned char" "char"s S-nail was broken for about
497 two and a half year since an E(nd)O(f)F(ile) condition would never
498 have been satisfied, resulting endless loops. Detected by the Debian
499 package build bot who hung endlessly when running "$ make test".
502 - Fixes to false signal handler restoration, partially false forever.
505 - Fix crashes in the error path of Zopen(). If a de-/compressor fails
506 Heirloom mailx would crash, and S-nail would have crashed in the debug
507 path and print "Alert: Invalid file pointer" in optimized code. Since
508 S-nail allows *file-hook-{load,save}-EXTENSION* the situation is much
509 worse, however. [8e7f0f4]
511 - Don't crash in `varedit' when $EDITOR doesn't start up. [5a5350b]
513 - The build system now sorts source files in order to honour
514 <https://reproducible-builds.org/>. [a939517]
516 - The build script has seen improvements. The (mysterious) hangs in VMs
517 are gone now that i have switched configuration evaluation to awk(1)
518 thanks to a suggestion by Aharon Robbins. In fact doing "$ make
519 CC=tcc devel" now takes the same time all-in-all that the mentioned
520 evalution took alone. [fa2e248] (Aharon Robbins)
522 This is true even if we know do a lot more of run tests instead of
523 plain link tests for native environment detection since the GNU
524 C library monster uses empty ENOSYS stubs for system calls it doesn't
525 provide. This is the reason why the Debian kFreeBSD S-nail package
526 doesn't work out by now. We are not aware of booting different
527 kernels with different feature sets than what we detected upon compile
528 time, though. I don't think we ever will. [3ee2d4c]
530 ChangeLog (purely technical)
531 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
533 - Dotlock file locking now ignores lock file creation failures on
534 readonly filesystems. Since the mailbox will be degraded to read-only
535 no dotlock file is needed. [40785bc]
537 And that really hurts: [3517800]! On Solaris NAME_MAX is set to the
538 minimum that POSIX allows (14), and we were not really prepared for
539 that. I.e., the lock for /var/mail/sdaoden would be
540 /var/mail/sdaoden.lock, we require at least one more byte for safe
541 lock file creation and yet included the terminating NUL in the
542 calculation, and whoops, dotlocking failed because of ENAMETOOLONG!
543 So do use pathconf(2) _exclusively_ if that succeeds to give an
544 answer. And we still have room for improvements that i as a C++
545 programmer with speedy dynamic Str objects would never thought i have
548 - Fix pathconf(2) usage. [31ce3e1] (Not wrong: Martin Sebor)
550 - First step to use the new *at() series of system-calls if available,
551 inspired by (Philip Guenther). [topic/time]
553 v14.8.5 ("Hen Harrier"), 2015-09-05
554 -----------------------------------
556 Credits John Dodson, Claudio Cappelli.
558 We welcome Claudio Cappelli in THANKS.
560 NOTES, ChangeLog (packager-affine)
561 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
563 - I've forgotten to add obsoletion warning messages in v14.8.4, so
564 running with enabled -d/*debug* -vv/2x*verbose* may be useful.
567 - A series of bug FIXes (which caused the "Hen Harrier" in the end):
569 . v14.8.4 bug: macro content will be added to the history. [28672e5]
571 . Fallout of massive not-yet-dead style and control flow change series
572 in February 2014, I.: the close-on-exec bit of temporary file
573 descriptors wasn't set. [8f58404]
575 . Fallout of massive not-yet-dead style and control flow change series
576 in February 2014, II.: temporary files were always created in the
577 current directory. Aloha, heh. [edc12c8]
579 . v14.8.4 bug: when `resend'ing messages a crash would happen when
580 generating the Message-Id: (control flow messed up when hastily
581 implementing extended -t parsing). [9e63ae6]
582 (Hello, Bob Tennent: i finally have added at least a simple `resend'
583 test. Don't your worry.)
585 . v14.8.4 bug: plugged a file descriptor leak in the dotlock code (one
586 side of the control pipe was leaked upon success; there you see how
587 large ulimit(3) limits are by default today). [ed5c8cf]
589 - When using -t and a template message recipients given on the command
590 line will now be joined into the message instead of being discarded.
596 - The `set' command will now mark out assembled variables if *debug* or
597 2x*verbose* is set. [2b6e64a]
599 - Added *smime-cipher* @433 option (i.e., generic variant of
600 *smime-cipher-USER@HOST*). [58804ea]
602 - Messages will now _only_ be saved in *DEAD* if *save* is set (POSIX).
605 - The (pretty useless for now) `pipe' command will now also print the
606 overall message info (it printed MIME part infos already). [e0a8196]
608 - NAIL_FILENAME_GENERATED is now nothing but a random string. [36097df]
610 - *debug* now implies no*record* and no*save*. [ca9f512]
612 - After almost three years i've finally heard what John Dodson said and
613 changed/restored behaviour of plain "address" message specifications
614 to reflect the original intent (and a bit POSIX) so we now have
615 A case-insensitive “any substring matches” search against the
616 ‘From:’ header, which will match addresses (too) even if
617 showname[339] is set [things are different if *allnet* is set]
618 [44cec1f] (John Dodson)
620 - ..and therefore we need the possibility to somehow perform "exact
621 boundary" matches: for this i've extended the "@" message
622 specification with a header-name "~" prefix and header abbreviations:
623 ‘f’, ‘t’, ‘c’, ‘b’ and ‘s’ will match ‘From’, ‘To’, ‘Cc’, ‘Bcc’ and
624 ‘Subject’, respectively and case-insensitively.
626 This message specification performs full text comparison, but even
627 with regular expression support it is almost impossible to write a
628 search expression that savely matches only a specific address
629 domain. To request that the content of the header is treated as a
630 list of addresses, and to strip those down to the plain email
631 address which the search expression is to be matched against, pre‐
632 fix the header name (abbreviation) with a tilde ‘~’:
633 '@~f@@a\.safe\.domain\.match$'
636 - New option: *sendmail-no-default-arguments* @426 [d983036]
639 - Do no longer make a difference in "no mail for user" and "missing
640 system mailbox". The latter caused yet an annoying error message even
641 with *emptystart*. [7abff87]
643 - New command `source_if' @187 is like `source' but don't fails if the
644 file cannot be loaded. That is to say, we do not yet support
645 "-f FILE@ tests nor `test -f FILE` shell commands for `if', sigh.
648 ChangeLog (purely technical)
649 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
651 - Unless Gunnar Ritter is directly affected the fourth clause of the BSD
652 copyright has been dropped, as has been done for NetBSD Mail.
655 - Quoted-printable encoding will avoid printing a soft newline if only
656 a single character is about to follow. [6b31542]
658 - The configuration script now shows what it is doing at the beginning,
659 to overcome those hangs that can be seen especially in VMs. [4c29cea]
661 - The configuration will do an automatic "make clean" when the
662 configuration had been updated. [9706734]
664 - We no longer generate a MIME message unless that is necessary. I.e.,
665 a plain 7-bit (US-ASCII) message without attachments send from
666 a system daemon is a plain RFC 822/2822/5322 message and doesn't
667 require any MIME header. [824257a]
669 - To avoid that DNS resolver becomes unusable due to ^C interruption.
670 Also fixes a possible leak in non-getaddrinfo(3) codepath (old boxes).
673 v14.8.4 ("Nameless bird (shot by Hemingway)", 2015-08-04
674 --------------------------------------------------------
676 Thanks for Jérémie Courrèges-Anglas for beating me to it.
678 NOTES, ChangeLog (packager-affine)
679 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
681 - Added support for the (BSD-licensed) idnkit[1] IDNA library which is
682 now in the base system of DragonFly BSD. We still only support
683 encoding, though. (And assume the hostname is in locale encoding.)
686 [1] <https://www.nic.ad.jp/ja/idn/idnkit/download/>
688 - I have rewritten the privilege-separated dotlock helper program,
689 because among others a SETGID one is of no use in todays world.
690 So it is now SETUID to the new PRIVSEP_USER.
692 . WANT_PRIVSEP and PRIVSEP_GROUP have been dropped.
694 . New option: WANT_DOTLOCK, by default enabled.
695 It is henceforth possible to strip any dotlock code off S-nail.
696 So either S-nail has complete dotlock support, including the
697 privilege-separated dotlock helper, or none at all.
699 . New variable: PRIVSEP_USER, by default "root".
700 It must be a privileged user that can be used to implement the new
701 strategy: we create the dotlock file and then fchown(2) it to the
702 UID and GID of the mailbox that we created it for. Like this the
703 owner of the mailbox (remember %USER, $USER, -u USER ..) will be
704 capable to remove the lock file herself. Or himself.
706 . No dotlocking was performed for reading, only for writing. I've
707 changed this. We also didn't perform any (file) locking at all when
708 updating non system-mailboxes, which i have changed, too.
710 . Fixed horrific bug: on systems without realpath(3), e.g., Solaris 9,
711 S-nail would not resolve symbolic links on the mailbox to lock,
712 potentially creating the lock file in the wrong directory.
714 . We now compare the inode/device/etc. of the mailbox file with the
715 information we collected a lot earlier from the open mailbox file
716 descriptor, and bail if they are not identical, to reduce attach
719 . The privsep helper now re-checks that it is capable to read (or
720 read/write) the mailbox it is creating a dotlock for, to reduce the
721 chance of being misused (by itself). I.e., it does so before
722 raising its privileges, say.
726 - The predefined CONFIG=urations have been changed a bit and now
727 "require" more options than they did before.
729 - Renamed WANT_ALL_SSL_ALGORITHMS to WANT_SSL_ALL_ALGORITHMS.
730 That was a no-brainer, default of "yes" remains, but it now can also
731 be "require"d. [910849e]
733 - The GitLab project repository URL has been changed and now is
734 <https://gitlab.com/sdaoden/s-nail.git> (leave off ".git" for browsing
740 - It has become possible to fixate the input character set of
741 attachments from the command line (without going over ~@):
742 when the -a @39 option cannot access(2) the file to be attached it
743 searches the filename for an equals-sign "=" and splits into filename
744 and character set shall it find one. A character set defined like
745 this is "fixated" and therefore no character set conversion occurs.
748 ./s-nail -d -s subject du@auch \
749 -aversion.h -aversion.h=KoI8-r -aversion.h=LaTin1 -aversion.h
751 >>> Content-Type: text/x-chdr; charset=US-ASCII
752 >>> Content-Type: text/x-chdr; charset=KoI8-r
753 >>> Content-Type: text/x-chdr; charset=LaTin1
754 >>> Content-Type: text/x-chdr; charset=US-ASCII
758 - In *debug* mode the content of the message that would have been sent
759 is printed on standard error not only in *smtp*, but also MTA mode.
760 E.g., as in the example above. [c106f35]
762 - S/MIME oops: S-nail yet didn't test for the "application/pkcs7-mime"
763 MIME type at all, but only for "/x-pkcs7-mime" (pre-standardized
764 variant), so that S/MIME messages generated by more modern MUAs (e.g.
765 Alpine) wouldn't have been understood!
766 And we do now use that MIME type ourself, as standardized by RFC
767 5751. However, we are still stupid and don't handle a signed message
768 inside a multipart/mixed message, neither do we support fully
769 encrypted messages (nothing but rfc822 member) etc. [10c2b16]
771 - *smime-cipher-USER@HOST* @431 values changed to versions without
772 hyphen, as that is what OpenSSL uses: e.g., AES256 not AES-256; the
773 latter versions are no longer documented and will be dropped with
776 - New variable *smime-sign-message-digest* [-USER@HOST] @437 can be used
777 to define the message digest for S/MIME signing. RFC 5751 mandates
778 a default of SHA1, by default available are also SHA256, SHA512,
779 SHA384 and SHA224, MD5 may be available, dependent on OpenSSL.
780 With WANT_SSL_ALL_ALGORITHMS more digests may be available. [2f6dac3]
782 - Using NAIL_FILENAME_GENERATED was prevented since some time since it
783 ended up longer than NAME_MAX (ENAMETOOLONG). [3bcbbfc,f632b5b]
785 - Heavily rewritten manual section "Signed and encrypted messages with
786 S/MIME" @35, giving a ready-to-go example for CAcert.org.
788 - Nicer output for `help' @126 / `?' @74 when given an argument:
789 if that is a command ghost we search for the expansion and do print
790 the (further expansion and) help for that if possible [cea8c20]:
793 save: Append <message-list> to <file>
795 s (save): Append <message-list> to <file>
798 s -> s (save): Append <message-list> to <file>
800 - No longer allowing recursive commands in macros to avoid that the
801 following can crash us (check can be bypassed):
810 This is a pity because "? call ouch" does no longer cause a reply,
811 but the real healing will take time.
812 Also the `source' command is now actively disabled during macro
813 evaluation -- this only works(/ed) by accidence and anyway non-
814 synchronously (the `source'd file will be loaded after the macro
815 evaluation has finished). The real healing for this is heavy stuff
816 and will remove a smart and fantastic idea from before 1979, but it
817 won't work out with macro support (see commit message for more upon
820 - And `source' will be actively forbidden in compose mode, too. It
821 never worked the way it should. [abd388c]
823 - Did -t @60 ever work for real? Now it does.
824 Even better it now "supports" some more header fields (References:,
825 In-Reply-To:, Message-ID:, and Mail-Followup-To:, but the latter will
826 be subject of a nice followup content massage) -- S-nail can
827 henceforth be used for git(1)s send-email command.
828 We also improved the interdependency of -t (with[out] From:, Sender:),
829 -r, *from* and *sender*, but i don't say it is perfect yet.
830 [6842f12,631d402,a86ca2d]
832 - Completely reworked *expandaddr* @373 handling, and you can now define
833 *exactly* what you want, e.g., "fail,-all,+addr,+file" will only allow
834 mail address or file recipients and hard error out otherwise.
835 Note that in order to make that work "restrict" has been changed to be
836 effectively "restrict,-all,+name,+addr", which matters in, e.g.,
837 "fail,-all,+file,restrict" which therefore truly is "restrict,fail"!
839 Even in conjunction with -t you should now see proper (-d / *debug*,
840 -v / *verbose*) messages for *expandaddr* caused address stripping,
841 or, with "fail", hard errors. [8668be3]
843 ChangeLog (purely technical)
844 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
846 - We again allow Message-Id:s to start with a leading slash, as in
847 "/p/forge/site-support/10.../...". [143372a]
849 - We now support multiline values in make.rc: to do so, escape the
850 newlines with a backslash "\", e.g. [621cbed,9cf4e7b]
853 if [ -d /var/spool/mail ]; then \
854 echo /var/spool/mail;\
859 - Lowered the memory pressure caused by malicious spam messages that
860 place hundreds of references into the References: header body.
861 And we don't use alloca(3) no more for such things, in order to lower
862 stack usage. [1c4b8c9,47a1a5c]
864 v14.8.3 ("Startled chicken"), 2015-07-05
865 ----------------------------------------
867 Credits go to Martin Neitzel!
869 NOTES, ChangeLog (packager-affine)
870 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
872 - Prefilling INCS and LIBS is finally honoured by the build system, just
873 as documented. [9a34822]
875 - In place of "packager-install" "doinstall" will also do.
877 - New `make.rc' option: WANT_ERRORS, by default enabled.
878 Will enable the new command `errors' @105 (#_105) and an error message
879 queue ring: error messages will no longer get lost but duplicated into
880 the queue, to be displayed in interactive mode via `errors'. This is
881 a finite ring which rotates oldest messages if it full.
884 - S-nail no longer offers hooks for group identity switching: it no
885 longer makes sense to install it SETGID to a mail group (shall anyone
886 has done so). [ac42d24]
888 - New `make.rc' option: WANT_PRIVSEP, by default enabled.
889 The dotlock'ing has been completely rewritten (see `make.rc' for
890 a longer explanation of traditional Unix mailspool locking, please).
892 In order to be able to create lock files in *any* SETGID mailspool
893 directory in which user system mailboxes may reside S-nail now ships
894 with a privilege-separated mini dotlock program (source in
895 `privsep.c'), which will be installed in the new also LIBEXECDIR (as
896 YOUR_MUA_NAME-privsep) SETGID to the group given by the also new
897 PRIVSEP_GROUP (default "mail").
899 This dotlock program will be used whenever a mailbox has to be
900 dotlocked which is owned by group that is not the group of the user
901 who is running S-nail, assuming that the file in question resides in
902 a SETGID mailspool directory.
904 The new variable *dotlock-ignore-error* @294 (#_294) now controls
905 wether it is a failure if creation of a dotlock file is not possible.
906 This variable is by default enabled if WANT_PRIVSEP is false.
912 - Fix file locking, which was broken since v14.8. [7f8ebc0]
915 - -e now works with given boxes; -e is mutual exclusive with -H and -L;
916 and then any of -e, -H and -L causes the mailbox opened in readonly
917 mode. [3bb05a2, 2cf15c1]
919 - In *debug* mode no process will be started for a set *smtp*, but
920 instead the message will be directly generated (on the error channel).
921 Also GSS-API authentication will no longer be performed even with
922 enabled debug, oops. [3333d71]
924 ChangeLog (purely technical)
925 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
927 - A readonly IMAP box is opened via EXAMINE not SELECT. [2d5259c]
929 - snprintf(3) and vsnprintf(3) are now required preconditions. [c58c7e9]
931 v14.8.2 ("Wandering albatross"), 2015-06-17
932 -------------------------------------------
934 Many thanks Bob Tennent, for reporting and testing!
936 NOTES, ChangeLog (packager-affine)
937 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
939 - Configuration will now find clock_gettime(2) in -lrt and
940 gettimeofday(2) as such on Linux. [47c9ea7,5e248d2,df7d77f]
943 - MANDIR now defaults to ${PREFIX}/share/man (not ${PREFIX}/man)
949 - Added missing condition clause in `if' expression parsing
952 ?0[ +mbox]? if $du @@ hey
955 ?0[ +mbox]? if $du @@ hey
956 `if' conditional: unrecognized condition -- near "du"
957 Expression: $du @@ hey
958 Left to parse: $du @@ hey
961 - Ooops, fix pipe-TYPE/SUBTYPE @403 with value "@" (a.k.a. treat as
962 plain text and display "as is"): i've broken that once i've introduced
963 the extended type markers for the `mimetype' command. Must have been
964 a Freudian error, sorry! [ea655de]
966 - Fix a bug introduced in nail 9.29, 2001-12-10: a temporary buffer is
967 closed with fclose() even though it is a registered file that instead
968 needs to be closed via Fclose(). This effectively results in
969 a double-fclose(3) of the underlaying file descriptor once the
970 registered files are cleaned up next, which happens either after
971 signal interruption and, since [65e0510] as of 2015-05-21, whenever
972 the command loop ticks. [97fcb97] (Bob Tennent)
974 v14.8.1 ("Tristan albatross"), 2015-06-11
975 -----------------------------------------
978 Ypnose, Tarqi Kazan, Dagobert Michelsen and OpenCSW.org, Gianluca
979 Ramunno, Bob Tennent.
981 We welcome Dagobert Michelsen in THANKS.
983 NOTES, ChangeLog (packager-affine)
984 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
986 $ In all the following noticable changes to the release candidate are
987 $ marked with a $ in the first column
989 - We have been ported to Sun Solaris!
990 Thanks to Dagobert Michelsen for giving me an account on OpenCSW.org!
992 - The build system will now really find strip(1). [54e91c4]
994 - WANT_TERMCAP fix: we simply passed tputs(3) a pointer to putchar(3)
995 though that may be a macro etc. [cc65bc3]
997 - The following variables can be used to overwrite utilities needed
998 during configuration and build:
1000 MAKE=, STRIP=, awk=, cat=, chmod=, cp=, cmp=, cksum=, grep=, mkdir=,
1001 mv=, tee=, rm=, sed=, tr=
1003 Note that rm(1), sed(1) and tr(1) are needed before `make.rc' is read.
1004 Fix: these will now also affect "make test".
1006 - WANT_AUTOCC now no longer sets compiler flags as of experience, but
1007 compiles a test program to actually detect wether the compiler will
1008 swallow the flag. This increases configuration time quite a bit.
1009 Users who really did use "make devel" possibly want to use "make
1010 CONFIG=DEVEL" followed by "make build" now.
1011 Note we now also test for -fPIE as well as relro,now,noexecstack.
1013 - WANT_SPAM_SPAMD is now decoupled from WANT_SOCKETS. [d247d86]
1015 - The configuration now also detects any changes on PATH, C_INCLUDE_PATH
1016 and LD_LIBRARY. [1038028]
1021 - Fixed importing of SHELL/LISTER/PAGER variables from the program
1022 environment. [940c7f1] (Ypnose)
1024 - Moved -X @64 command line option handling before attachment
1025 evaluation, so that, e.g., `mimetype's registered via it will already
1026 be seen when classifying attachments. [5d9742f]
1028 - Honour *asksign* @274 again, even if *askatend* @270 or *bsdcompat* @281
1029 are not set. This also changes *askattach* @271 as we'll only ask for
1030 addition of attachments if there are none yet. [e054d6a] (Tarqi Kazan)
1032 - Support OpenSSL 1.1.0 and above: it obsoletes the more-than-a-decade
1033 old SSLv23_client_method() in favour of a new TLS_client_method()
1034 (instead of using some "magical" constant like, say, "SSL_METHOD_ANY",
1035 but who am i). [c35b567]
1037 - Generic file (mailbox) load and save hooks have been introduced:
1038 *file-hook-(load|save)-EXTENSION* @374,@375, e.g.:
1040 set file-hook-load-xy='echo >&2 XY-LOAD; gzip -cd' \
1041 file-hook-save-xy='echo >&2 XY-SAVE; gzip -c' \
1042 record=+null-sent.xy
1044 One could think about using all-encrypted mailboxes, or the like.
1045 Note that before v15.0 these variables may not be changed while
1046 a mailbox handled by these hooks is open. [b4c2c37] (Tarqi Kazan)
1048 - When DNS resolving fails we now print error messages.
1049 And then, if it fails because of an unknown service (protocol), we
1050 check for the protocol and retry shall we have a well-known port
1051 number builtin (smtp, submission, smtps, pop3, pop3s, imap, imaps).
1052 [5f52370, (3f189f9)] It is not wrong to credit (Gianluca Ramunno)
1054 - One may now force treatment of addresses as files with the new "./"
1055 or "/" prefixes -- until now it wasn't possible to address files if
1056 the addressee includes an at sign, now "./me@here.com" will do, just
1057 as will "/me@here.com". [2cf5890,0da473f] (Bob Tennent)
1059 - Fix *record-resent* @329, which never made it to *record* @414 since
1060 [a11935b], but instead save the message in a file named after the
1061 addressee! [a82af9f] (Bob Tennent)
1063 - Fixed signal handler uninstallation in sopen() (DNS lookup and socket
1064 creation): v14.8.0 could be forced in endless loop after failed DNS
1065 lookups due to this. [3cca23b]
1067 - Fixed possible double-free (causing a crash) after failed SSL
1068 certificate verification (*ssl-verify*=strict etc.) with OpenSSL
1069 versions that support SSL_CONF_CTX (1.0.2+). [c691726]
1073 . The builtin HTML filter will now silently discard carriage-return
1074 characters (looks better in e.g. less(1)). [cf4d800]
1075 . When reopening the same box we now recognize if changes had been
1076 written, forcing a reread of the box in order to display the actual
1077 real content. [7dfbd38,0835212,a15dfed]
1078 . `netrc' output changed, so that the output could (in theory) be fed
1079 back into S-nail again in order to gain the same settings. [a9a2722]
1080 . *pop3-keepalive* @410 gained (@USER)?-HOST forms [69cae68]
1081 . *imap-keepalive* @387 gained (@USER)?-HOST forms [9a8c929]
1082 . Do not use the builtin random generator if we find a suitable one in
1083 the host environment. [0e01aeb,6bcb430,fc846c6] (Bob Tennent)
1084 . The builtin HTML filter will now also expand entities in parameter
1086 $ . *crt* will now only be checked when attached to a terminal device;
1087 $ and no*crt* will now be honoured. [2508c32]
1089 ChangeLog (purely technical)
1090 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1092 - Solaris port resulted in a lot of changesets for the build system.
1093 - I didn't use git(1) rebasing and the [crawl] branch but only [master].
1094 And see where that ended: S-nail would have 10000 fossil commits!
1095 - Plugged some memory leaks.
1097 v14.8.0 ("Albatros"), 2015-04-30
1098 --------------------------------
1101 I'm glad and happy to announce "Albatros" after about seven months of
1102 development. Development that brought many new features, bugfixes,
1103 technical overhauling and behaviour tweaking. Shall you ever have been
1104 interested in BSD Mail or its deriviatives you might want to give it
1107 "Albatros" is indeed the first version of the codebase as such that
1108 should allow IMAP->Maildir->MBOX->Maildir->IMAP message roundtripping
1109 without causing possible message splitting due to faulty From_
1110 detection / encoding. It also generates compliant MIME parameters.
1112 Note there are incompatible changes, documented below. And it is also
1113 advisable to try out existing configurations with enabled *debug* and/or
1114 *verbose* (-d, -vv) in order to check for "obsoletion" warnings.
1115 (Here "obsolete" would refer to v15, of course.)
1117 Credits and Thanks go to Ypnose, Jérémie Courrèges-Anglas, Josef Jurek,
1118 Gavin Troy, Rich Salz, Martin Brandenburg, Bob Tennent, Dominic Meskys
1121 We welcome Jérémie Courrèges-Anglas, Josef Jurek, Rich Salz,
1122 Dominic Meskys, Peter Bray, Dirk-Wilhelm Peters and Martin Brandenburg
1124 Apologies to Dirk-Wilhelm Peters and Martin Brandenburg whom i had
1125 forgotten to add to THANKS at first glance once i've added this file; it
1126 was nothing but an oversight.
1128 I also say «Thank you» to GitLab.com – i've mirrored the S-nail git(1)
1129 repository (alongside others) to this free service.
1131 Credits finally also have to go to Coverity.com [1] which helped to find
1132 some bugs; the claim of a 0.00 defect density after a Friday 13th test
1133 must have been an error from their side, though, as well as that the
1134 page [1] still remains at a test with a defect density of 0.01, since
1135 i've posted yet another run that must have ended with 0.00. (Note the
1136 codebase was tested without IMAP code, i.e. my _next_ developer branch.)

1140 NOTES, ChangeLog (packager-affine)
1141 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1143 $ In all the following noticable changes to the release candidate are
1144 $ marked with a $ in the first column
1146 + Crawling along the path of CVE [topic/cve-2014-7844.2]: to enable MTA
1147 arguments after -- the new *expandargv* @372 must be set. More below.
1149 + Even more crawling along the path of the CVE i decided to replace the
1150 wordexp(3) based shell word expansion mechanism with an entirely new,
1151 internally implemented restricted one, but complete mitigation will
1152 take time. This has consequences in respect to backslash escaping in
1153 file names (shall you ever have used such a filename with S-nail and
1154 its predecessors, of course, and only ...).
1155 Please see [topic/fexpand.2] below.
1157 + A new member for the *attrlist* @351 variable (for unsure spam status).
1158 Since a user setting with a false length will be ignored yet causes an
1159 error message this is a backward incompatible change. [topic/spam.2]
1161 - New make.rc option: WANT_ALL_SSL_ALGORITHMS (enabled).
1162 See make.rc and *smime-cipher-USER@host* @427 below. [topic/ssl.1]
1164 - The make.rc option WANT_IPV6 is gone; we use the respective standard
1165 library facilities automatically whenever possible. [999e79a]
1167 - New make.rc option: WANT_TERMCAP (disabled).
1168 See *term-ca-mode* @345 below. [topic/termcap]
1170 - The make.rc option WANT_SPAM has been dropped. Instead we have (see
1171 [topic/spam.2] below for more):
1173 . WANT_SPAM_SPAMC (default off):
1174 Rather identical to the former WANT_SPAM (interaction with spamc(1)
1175 from spamassassin(1)), but internally improved.
1176 . WANT_SPAM_SPAMD (default off):
1177 Direct interaction with spamd(1) from spamassassin(1) via a local
1178 unix(4) domain socket.
1179 . WANT_SPAM_FILTER (default on):
1180 Freely configurable hook programs, e.g., bogofilter(1).
1182 - It turned out that the manual wasn't mandb(1) compatible. [f5ab838]
1184 - New make.rc option: WANT_FILTER_HTML_TAGSOUP (enabled).
1185 S-nail now ships with a very primitive HTML-to-text converter.
1186 It'll be used for HTML parts automatically if no pipe handler is
1187 installed (and the builtin mime.types haven't been changed).
1188 This works because of the new TYPEMARKER extension to mime.types(5) as
1189 documented for [topic/mime.types.2] below.
1190 (It is quite experimental but i think it rocks except it can be fooled
1191 since it doesn't know about double quoted strings, e.g., <a href=""
1192 onmouseover='javascript:alert("> This is plain text you see, oops");'>.
1193 $ Yet it is ment for displaying HTML mails, and it works really well.
1194 $ It doesn't support non-standard type="quote" attributes nor even-more
1195 $ non-standard CSS classes "gmail_quote" or whatever it's name was --
1196 $ these are used in the wild to generate automatic mail quoting, which
1197 $ has resulted in an immense amount of top-posting; but maybe there will
1198 $ be a S-nail v14.8.1 which will implement those, to ease the pain.
1199 [topic/html-tagsoup]
1201 $- List output of `alias' @78, `ghost' @123 and `shortcut' @181
1202 $ uses a new syntax that should (in theory) make it possible to feed
1203 $ the output back into S-nail. [2913df3]
1204 $ Ditto `set' @178 unless *bsdcompat* or *bsdset* are set. [373cc8a]
1206 $- *keep* @308 will also affect secondary mailboxes (because *emptybox*
1207 $ has been obsoleted, see below). [5fa5f8b]
1209 $- New make.rc option: WANT_FORCED_STACKPROT (enabled with WANT_DEVEL or
1211 $ In conjunction with WANT_AUTOCC this will trigger stack protectors
1212 $ if the detected compiler does support them. (Before they were only
1213 $ enabled if WANT_DEBUG was set, automatically.)
1215 + v14.8 is the last release with IMAP support, which has been removed
1216 from the developer's [crawl] branch for quite some time already.
1217 He really hopes he can affort to readd support sometime after v15.0.
1222 - S-nail now knows about named booleans (e.g., `localopts' @133 or
1223 interactive approval prompts can now be given any of 1/yes/true/on or
1224 0/no/false/off, case-insensitively; note this is true for the make.rc
1225 $ system, too) and so-called "quad" options (either normal boolean or
1226 $ "ask-BOOLEAN", which, in interactive context, will be prompted with
1227 $ default values; the default value is chosen in non-interactive mode).
1228 $ (on/off support not in the RC.)
1231 - The `if' @128 combo:
1233 . gained <, >, <= and >= tests;
1234 ==, !=, <, <=, >=, > will try to convert their arguments to numbers
1235 and perform their test numerically, if possible, [143d409]
1236 . `if' supports boolean (as above) arguments, [topic/ifpimp]
1237 . `if 1'+ return value fixed, [topic/ifpimp]
1238 . `if'+: on syntax error, NOOP anything 'till `endif', [topic/ifpimp]
1239 . `if'+ now support bracket groups, AND-OR lists and unary ! (not),
1240 note that the separating spaces are required: [topic/ifpimp]
1242 if [ [ true ] && [ [ $debug ] || [ $verbose ] ] ]
1245 if true && $debug || $verbose
1246 echo Left associativity, as is known from the shell
1248 if ! ! true && ! [ ! $debug && ! $verbose ]
1249 echo Unary operator support
1252 . `if'+ now support new case-insensitive (ASCII) substring operators
1253 =@ and !@: [topic/ifpimp]
1255 if $features =@ "regex"
1256 if $TERM =~ "^xterm.*"
1257 echo ..in an X terminal
1261 $ . `if'+: the three argument forms can now be given variables also on
1262 $ the right hand side: [topic/ifpimp]
1264 $ set xtest='^xterm.*'
1265 $ if $TERM =~ $xtest
1266 $ echo Variables as right hand value
1269 - `unalias' @198 learned that * means "all aliases".
1270 Fixed: faulty list-head relinking caused "dead" aliases (since ever)
1273 - `unshortcut' @219 learned that * means "all shortcuts".
1274 `shortcut' @181 in turn can now define multiple shortcuts in one go
1277 ?0[ /var/mail/steffen]? sho you 'any one' me 'no "one"'
1278 ?0[ /var/mail/steffen]? sho
1279 shortcut me "no \"one\""
1280 shortcut you "any one"
1281 ?0[ /var/mail/steffen]? unsho*
1282 ?0[ /var/mail/steffen]? sho
1283 ?0[ /var/mail/steffen]?
1285 - S-nail learned how to deal with mailing-lists in respect to
1286 Mail-Followup-To headers etc. (manual: "Mailing lists" @21):
1288 . new commands `(un)?ml(list|subscribe)' to let S-nail decide which
1289 addresses are mailing-lists, [topic/names]
1290 . *headline* learned %T format to display message recipient flags:
1291 "L" for a mailing-list, "S" for a subscribed one, [topic/names]
1292 . new variable *followup-to-honour*, [topic/mft]
1293 . new variable *reply-to-honour*, [topic/mft]
1294 . new command `Lreply', forcing a list-only `reply' if possible.
1295 When `Lreply'ing to messages which seem to originate from
1296 mailing-lists (contain a "List-Post:" header), then S-nail will
1297 treat the list address as a known mailing list (as via `mlist').
1299 (It is advisable to try out several different combinations of non-/
1300 subscribed mailing-lists in conjunction with `reply', `Reply' and
1301 `Lreply' with *debug* set in order to get used to how S-nail will
1302 modify the address lists; the results should be quite logical
1303 though.) [topic/mft]
1304 . For convenience `reply' and `Lreply' can now be used to reply to
1305 multiple messages in one go (each message will still be handled by
1306 itself, we simply start over internally). [topic/mft]
1308 - `unset' @217 no longer "fails" for unset variables, but only prints
1309 a message in *debug* or *verbose* mode. This changes traditional,
1310 decade-old behaviour, but shells don't even say something in (*debug*
1311 or) *verbose* mode, and it really simplifies things. [topic/okeys-attr]
1313 - SSL/TLS changes: [topic/ssl.1]
1315 . new variables: *ssl-cert-HOST* @451, *ssl-key-HOST* @456,
1316 *ssl-method-HOST* @457, *ssl-verify-HOST* @461,
1317 . *ssl-v2-allow* has been dropped,
1318 . *ssl-verify* @461 and *smime-cipher-USER@HOST* @427 use
1319 case-insensitive matching for value checks,
1320 . new variable-chain: *ssl-protocol* @458 (the introduction of which
1321 obsoletes *ssl-method* @457, see below),
1322 . new variants of *ssl-cipher-list* @452: *ssl-cipher-list-USER@HOST*,
1323 *ssl-cipher-list-HOST*,
1324 . new variable: *ssl-config-file* @453,
1325 . *smime-cipher-USER@HOST* @427 dropped builtin support for the
1326 obsolete RC2-40 and RC2-64 ciphers -- use the make.rc option
1327 WANT_ALL_SSL_ALGORITHMS to readd support,
1328 . with SSL_CONF_CTX support (OpenSSL v1.0.2+) the values of the
1329 following variables (and variants) will be parsed by OpenSSL instead
1330 of S-nail, offering more user and packager flexibility:
1331 *ssl-cert* @451, *ssl-cipher-list* @452, *ssl-key* @456,
1332 *ssl-protocol* @458.
1334 E.g., shall a new OpenSSL ship with TLS v1.3 S-nail doesn't need to
1335 be adjusted in order to support TLS v1.3, all there is to do is that
1336 the user has to adjust her *ssl-protocol* setting.
1337 This is at least the theory. :)
1338 And maybe OpenSSL (will) offer(s) symbolic constants like "NEWEST"
1341 - Folder hooks have been extended:
1343 . if there was no *folder-hook-FULLNAME* @376 we'll try
1344 *folder-hook-+NAME* if the mailbox NAME resides in *folder*, e.g.,
1345 the author has "folder-hook-+sent=MACRO" and all his *record*
1346 variables are "record=+sent", therefore MACRO can be shared in
1347 between all accounts with a single hook definition. [a5a4d89]
1348 . `localopts' @133 can now be used in folder hooks: the covered
1349 settings will be reverted once the folder is left again.
1350 $ (I know for sure someone asked for this long ago, directly after
1351 $ `localopts' came up first, but i couldn't find the corresponding
1352 $ message. Sorry!) [2c67091]
1354 - More security control à la CVE 2014-7844, possibly for the first time
1355 enabling safe usage of S-nail via CGI: [topic/cve-2014-7844.2]
1357 . fixed *sendmail-arguments* @420 parsing:
1358 *sendmail-arguments*='-F "Dubi Da"' will now result in <"-F" "Dubi
1359 Da"> not <"-F" ""Dubi Da"">,
1360 . new command line argument "-." @67 forcefully terminates options
1361 and enters send mode. I.e., using this option avoids possible
1362 misinterpretation of the following arguments.
1364 This operation is usually reserved for --, but since S-nail passes
1365 anything after -- to the MTA (but read on) i had to invent something
1366 $ else. Also, -. forcefully enters send mode, which -- couldn't have
1367 $ been overloaded to do.
1368 . New variable: *expandargv* @372: in equal spirit to *expandaddr* @371
1369 this one is required in order to pass arguments after -- to the MTA.
1370 If set to "fail" existence of such arguments is a hard error,
1371 "restrict" likewise except in interactive mode or in conjunction
1372 with the -~ or -# options.
1373 . *expandaddr* @371: new special value "fail" causes presence of
1374 extended recipient addresses to be treated as a hard error.
1375 $ In fact this is now interpreted as a comma separated list and may
1376 $ also include the string "noalias", disallowing non-network-addresses
1377 $ in the remaining (non-"extended") recipient addresses -- note this
1378 $ applies to system global aliases only, not to those of `alias'
1379 $ (except for their content, of course); "noalias" is a hard error in
1380 $ combination with "fail".
1382 - `unaccount' @197 and `undefine' @201 learned that * means "all
1383 accounts" and "all macros", respectively. [4c09114]
1385 - Spam handling has been rewritten completely, revealing a very old
1386 misbehaviour in nail's subprocess handling (malloc in signal handler).
1387 Please reread the manual section "Handling spam" @37 for more.
1388 The motivation was also that bogofilter(1), sylfilter(1) etc. can
1389 export their databases, so should the author ever find time to
1390 implement spam handling in C like his predecessor it will be possible
1391 to continue to use those databases: [topic/spam.2]
1393 . *headline* @380 format %$ has been fixed,
1394 . when working on multiple messages the operation is cancelled if an
1396 . new variables: *spam-interface* @436 chooses the, well, ...
1397 This one has extensive documentation. Plus the interface dependent
1398 *spamc-command* @438, *spamc-arguments* @439, *spamc-user* @440,
1399 *spamd-socket* @441, *spamd-user* @442,
1400 *spamfilter-ham* @443, *spamfilter-noham* @444,
1401 *spamfilter-nospam* @445, *spamfilter-rate* @446,
1402 *spamfilter-spam* @447 and *spamfilter-rate-spamscore* @448.
1403 . The *attrlist* @351 variable gained a new slot for an unsure-spam
1404 status (default character is ~).
1405 Messages with that flag can be specified via the :S colon modifier.
1407 - Fix: even though -# @66 implies *sendwait* @335 a user should have the
1408 option to turn *sendwait* off again. [4274bed]
1410 - Completely reworked mime.types(5) handling, note the backward
1411 incompatible drop of `mimetypes': [topic/mime.types.2]
1413 . dropped the `mimetypes' command,
1414 . new commands: `mimetype' @138 and `unmimetype' @209,
1415 . *encoding* @369 is now parsed case-insensitively,
1416 . *mime-counter-evidence* @390 gained new bit 3 to indicate the desire
1417 to forcefully overwrite MIME types if we think we know it better,
1418 . *mimetypes-load-control* @391 gained an extension that can be used to
1419 load more and specific files, which in addition may make use of
1420 a new non-portable S-nail-specific TYPEMARKER extension. The manual
1421 section "The mime.types files" @32 has been rewritten accordingly.
1422 (In short: mime.types(5) lines can be prefixed by @, @h@ or @H@, for
1423 plain text, builtin HTML filter (plain text fallback), ditto
1424 (without fallback).)
1425 $ . The builtin MIME types now make a lot of use of the @ and @h@
1426 $ TYPEMARKER extensions, so that you possibly can get rid of a lot of
1427 $ pipe-TYPE/SUBTYPE=@ plain-text type hooks, shall you have used them.
1429 - Support for RFC 2231 has been added. This means that S-nail generates
1430 truly MIME compliant messages and no longer requires help from other
1431 MUAs! In fact MIME parameter handling has been rewritten completely.
1434 - On the long run shell word expansion (via wordexp(3)) will be replaced
1435 by a new, restricted (and thus (hopefully) safer), internally
1436 implemented path expansion mechanism that only supports ~/ -> HOMEDIR
1437 and $SHELLVAR / ${SHELLVAR}.
1438 Since the original expansion is *so* hardwired that'll take time, for
1439 now it is used for attachments only, but here all through the way.
1441 But where it is used already it has consequences regarding backslash
1442 escaping; to improve user experience a bit `~@' @239 will display the
1443 escaped filename so that users only have to hit ENTER to accept paths:
1444 e.g., "diet\ is \curd.txt" will show up as "diet\\ is \\curd.txt".
1445 And, e.g., the test script does the following for RFC 2231 (excerpt):
1447 MAILRC=/dev/null "${SNAIL}" ${ARGS} -Snodot \
1448 -a "ma'ger.txt" -a "mä'ger.txt" \
1449 -a 'diet\\\ is\ \\curd.txt' -a diet \"is\" curd.txt \
1450 ^ ^ NOTE: 0x00A0, NBSP
1451 -a ✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆✆.txt
1453 The introduction of the manual section "COMMANDS" @5 has been updated
1454 accordingly. Also see -a @39. [topic/fexpand.2]
1458 . Multiple crash-causing bugs regarding `source' @185, also if used
1459 via `~:source', have been fixed. [aafb688,6979c73,4c6dfc2]
1460 . The NAILRC environment variable is no longer supported. [104c254]
1461 . The *Replyall* variable has been dropped as it was only an alias
1462 for the POSIX standard *flipr* @296 variable. [topic/mft]
1463 . New variables: *version*, *version-(major|minor|update)*,
1464 *features*. [topic/okeys-attr]
1465 . `varedit' @224 can be used to create variables. [topic/okeys-attr]
1466 . New variable: *charset-unknown-8bit* @357. [9b672f6]
1467 . *smtp-auth* @434 now defaults to "plain" (if *v15-compat* is set).
1468 (Josef Jurek, Gavin Troy) [dcbb31a]
1469 . All obsoleted: *autothread*, `thread' and `unthread'.
1470 Use *autosort*=thread, `sort thread' etc. instead. [ef16f43]
1471 . *showlast* @336 should have gained meaning. [4213d52] (Gavin Troy)
1472 . If the -r @57 option is given a full name specification (rather
1473 than only an address), pass the MTA the respective address parts
1474 via -F and -f. [dd90c14]
1475 $ Also try to pass -F _and_ -f if an empty argument was given to -r
1476 $ but *from* @378 (or, say, "From:") includes a full name. [5f68921]
1477 . New variable: *term-ca-mode* @345 (for WANT_TERMCAP). In
1478 interactive mode S-nail can now be forced to use ti and te termcap
1479 entries; in conjunction with a PAGER that does too ... [topic/termcap]
1480 . `ghost' @123 gained a new mode and tweaks (see manual). [8a49b12]
1481 . -r @57 option: fixed -h output and manual. [9a1a303]
1482 (Martin Brandenburg)
1483 . With *debug* or 2x *verbose* command lines (including those read
1484 from files) are now traced. [06042c4] (Bob Tennent)
1485 . NAIL_TMPDIR (new) and TMPDIR environment variables are now
1486 (guaranteed to be) set in pipe hooks. [a1cfb02]
1487 . "Subject:" Re: trimming: MIME decoding is now performed. [ede7c7d]
1488 . New variants of *pop3-bulk-load* @320: *-[USER@]HOST*. [5f5ae10]
1489 . *crt*=0 @366 now really works. [22f1477]
1490 . Maildir code now uses string relaxation which drastically reduced
1491 memory usage for large mailboxes. [d1c945f]
1492 And for the first time it performs real memory cleanup. [e549110]
1493 . Improved error message on MTA exec failure. (Dominic Meskys)
1494 . Fix: "setenv noVAR" would have set noVAR. [3c1f886]
1495 . When `setenv' is used to set any of HOME, USER, TMPDIR it'll be
1496 reflected by our internal variables. (Still hacky as special code
1497 is needed to do so; also "set HOME=x" shadows HOME for "varshow
1498 HOME" instead of being rejected. Future cleanup work.) [3f03b80]
1499 . Colon modifiers can now be joined, as in "f :uas". [8b6c259]
1500 $ . Maildir code did faulty From_ line detection, resulting in any
1501 $ non-quoted "From " line to start a new message (e.g., when doing
1502 $ things like "copy * MAILDIR" we could have f...ed up completely).
1503 $ Seems to have been added with Heirloom mailx 11.6 ([faf4b65],
1504 $ 2004-09-07). Neither goes credit to Jacob Gelbman nor to Robin
1505 $ Stjerndorff for messages to nail-devel@ on 2015-01-21 and
1506 $ 2015-02-20, respectively. :-)) [ae539c9]
1507 $ . *emptybox* has been obsoleted. *keep* @308 will also affect
1508 $ secondary mailboxes, and then both only deal with local regular
1509 $ MBOXes anyway, not to e.g., maildir files nor IMAP boxes. [d747c0a]
1510 $ . `unghost' @207 learned that * has to drop all ghosts. [34a92a5]
1511 $ . NAIL_TMPDIR (new) and TMPDIR environment variables are now
1512 $ (guaranteed to be) set for *agent-shell-lookup* @350. [5c3d7b5]
1513 $ . Things like "copy * MAILDIR" from within an IMAP (or POP3?) mailbox
1514 $ to a Maildir mailbox should now work again. [d747c0a]
1515 $ . IMAP code did faulty From_ line detection, resulting in some
1516 $ non-quoted "From " line to start a new message (e.g., when doing
1517 $ things like "copy * MAILDIR" we could have f...ed up completely).
1518 $ Present in Heirloom mailx since ever ([^b4ad9f2]). [66e3c93]
1519 $ . New variable: *mbox-rfc4155* @312: because of all the bugs in From_
1520 $ quoting etc., err, no. "Albatros" will last. I've just touched
1521 $ a lot of stuff regarding MBOX writing: From_ quoting (which may
1522 $ happen whenever we save already existent data in a MBOX, shall
1523 $ the original generator not have taken appropriate steps to ensure
1524 $ "false" From_ lines can't happen (S-nail does)) is now definitely
1525 $ POSIX compliant, meaning that we may quote much too much lines.
1526 $ So set *mbox-rfc4155* and we generate RFC 4155 compliant MBOX files,
1527 $ possibly leaving behind backward POSIX-only software. [70ba3ef]
1528 $ . New command line option: "-X cmd" @64 will execute "cmd" right
1529 $ before normal operation starts. The only option to execute commands
1530 $ in non-interactive mode when reading of resource files has been
1531 $ actively suppressed. This is an experimental feature. [d202869]
1533 ChangeLog (purely technical)
1534 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1536 . Improved output flushing, avoidance of printing of useless
1537 output (especially smoothens *editalong*). [topic/stdout-fflush]
1538 . String relaxation is now everywhere (but IMAP), the builtin buffer
1539 sizes were reduced to 1/3.
1540 . Again a manual review. The manual now supports mdocmx(7).
1541 . Using builtin ARC4 pseudo-random for random generation.
1542 . Better signal handling here and there.
1543 . Fixed most "unpluggable memory leaks" by plugging them via chains of
1544 signal handlers and longjmps. Terrible. But no more leaks.
1545 . A lot of this and that. (Really.)
1546 $. Slightly more tolerance for faulty Base64 encoding in message text
1547 $ parts. No real healing possible today, but requires v15.0 environment.
1548 $ This, however, only affects invalid data that, e.g., OpenSSL doesn't
1549 $ even give any output for! [54137fd,4d59cca]
1551 I didn't make it to improved message selection.
1552 And i also can't seem to find the necessary peace of mind to do a real
1553 review with this codebase, it's always that i start off doing something
1554 non-reviewish; but i'll see the day (what i hope).
1557 The content has been vaporised. Ways to access the leakage are
1558 documented in the newest announcement at the top of this file.
