21 Jan Chaloupka (jchaloup AT redhat DOT com) reported on nail-devel@ that
22 Heirloom mailx can be crashed by setting *smtp* in combination with with
23 *from* effectively set to a NULL string. I first was optimistic, but it
24 turns out S-nail can, too.
29 Fixes maildir code which was broken in May (too).
30 Readds auto-detection of compressed boxes (i.e., if `$ Fi mybox' is
31 executed and `mybox' doesn't exist, but `mybox.bz2' does, then the name
32 is automatically expanded and `mybox.bz2' is used instead).
33 Sorry for the inconvience.
38 Thanks to Mantas Mikulėnas (grawity AT gmail DOT com).
40 This is a bugfix release which fixes a regression in the handling of
41 user credentials when *v15-compat* is not set, introduced in v14.7.1,
44 In other words, $folder *requires* the @ to be percent-encoded, but
45 $password requires the *opposite*.
47 And that is not valid when *v15-compat* is not set.
52 Thank you: Gavin Troy, Bob Tennent (rdt AT cs DOT queensu DOT ca),
58 v14.7.2 brings incompatible credential lookup changes when *v15-compat*
59 is set; the lookup order now is:
61 - *user-HOST*, *user*, [.netrc] ...
63 - *password-USER@HOST*, *password-HOST*, *password*, [.netrc] ..
65 Changelog in reverse order, oldest first.
67 ChangeLog (packager-affine)
68 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
70 - New configuration option WANT_AGENT to support *agent-shell-lookup*
71 (, -HOST, -USER@HOST) lookups of potentially encrypted password
72 storage (inspired by Gavin Troy) [b2d41d3,516a7f0]
74 - MAILSPOOL is now automatically set to /var/spool/mail if that
75 directory exists, only otherwise we use /var/mail [4a83018]
77 - WANT_GSSAPI is again enabled by default - Tarqi Kazan has correctly
78 pointed out that the system environment at compilation time is likely
79 to reflect the politics and/or preferred configuration of packagers,
80 and self-compilers have always the chance to configure themselves
81 (Tarqi Kazan) [398eb29]
86 - `un{,save,fwd}{ignore,retain}': let '*' mean 'all fields' [a1f1da9]
88 - Bugfix: `setenv' takes 1-1000 arguments, not exactly 2 [daf2ea8]
90 - New command: `varedit' edits the value of an existing variable in
93 - New commands: `File' (and `Folder') explicitly open a mailbox in
94 readonly mode, thus finally offering the possibility to avoid flag
95 updates etc. whenever so desired [b1f5f2d]
97 - Bugfix: since May the header display would display tabulators in an
98 UTF-8 environment as replacement characters [870b314]
100 - *mime-counter-evidence* now is a valued option. Set bit two (value
101 two) and the detected real MIME type is carried along with the MIME
102 part so that it is used instead of `application/octet-stream' to
103 lookup possibly registered *pipe-CONTENT/SUBCONTENT* handlers.
104 (Bob Tennent) [81473f8]
106 Also pipe handlers will now be passed several MIME informations via
107 environment variables, please see the manual for more.
108 (inspired by Bob Tennent)
110 - Resource file loading now prints a diagnostic when loading was stopped
111 due to a processing error. This behaviour is also required by POSIX.
112 (Bob Tennent) [fd42684]
114 - Incompatible changes in credential handling, as above.
117 - *netrc-lookup* is now a real chain and has -HOST and -USER@HOST
118 variants (though the latter only for password lookups) [59fc226]
120 - .netrc machine names are now lowercased before use [28c6fee]
122 - The manual has seen some reorderings, a TOC will be shown if you
123 '-dWANT_TOC=1' when using *roff(1) (as has been done for the online
126 - There is a new file `THANKS' [6b5cb3e]
128 ChangeLog (purely technical)
129 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
131 - IMAP and IMAP cache now use string relaxation which *drastically*
132 reduces memory usage on large mailboxes [e5598ce]
134 - Fixed compilation on old OpenBSD installations without wordexp(3) as
135 well as with GSS-API and WANT_AMALGAMATION and now using #pragma's to
136 get rid of some warnings [topic/ccstuff]
141 Thanks to Georg Schlisio (g DOT schlisio AT dukun DOT de),
142 Wiesław Magusiak (wiemag AT poczta DOT onet DOT pl), Tarqi Kazan and
145 Very special thanks: Gavin ".. .. Speeding kills. .." Troy from Ireland
146 and Ypnose "Gloria?? C'est une mouton!" from France.
148 Changelog in reverse order, oldest first.
150 ChangeLog (packager-affine)
151 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
153 - WANT_NOGETOPT is gone. [73f0605]
155 - WANT_NETRC: new option (on by default; see below). [topic/netrc]
160 - Manual slightly improved in respect to LC_ALL etc. settings.
161 The knowledge treshold value is much too high for a normal user;
162 i hope that at some later time we can offer much more (at least
163 optional) automation on the protocol level (e.g., timeout values,
164 protocol features supported by servers etc.), at which time we will be
165 able to make the manual more user friendly. (Georg Schlisio)
166 [56fab16,bd1e11f; ArchLinux Wiki]
168 - The `@' search command has new "header" keyword, which searches in all
169 headers. Shortcuts: "<" = "header", ">" = "body", "=" = "text".
170 ("body" and "text" still perform full text searches _including_ MIME
171 part header content.)
174 - The -O command line option is legacy and will vanish in v15.0.
175 Arguments to the MTA can henceforth be passed after a `--' separator
176 on the command line, as in
177 echo bla|s-nail -vvd -s sub some@where -- MTA ARGS MADE EASIER
180 - New *sendmail-arguments* option; content will be (converted to list
181 and) joined onto other MTA command line arguments (Wiesław Magusiak)
184 - *colour-pagers* is gone -- instead we have *colour-pager*, which is
185 a boolean and off by default. We again set LESS (and LV) environment
186 variable(s) to automatic turn on colour support in $PAGERs, but only
187 if the variable in question is not yet set. (That is -- in order to
188 get coloured $PAGER you at least have to set *colour-pager* now.)
189 (Tarqi Kazan) [b794f5e]
191 - Terminals no longer need to be added to *colour-terms* if their name
192 (in $TERM) includes the string "color". (Gavin Troy) [ce2c7f6]
194 - Karol Blazewicz opened a discussion in the ArchLinux Forum (s-nail
195 14.7-1 doesn't work [1]) but i didn't realize his actual problem --
196 luckily Gavin Troy wrapped his head around the real problem, and that
197 finally opened my eyes against a whole can of worms in the new URL
198 and credential handling!
200 Then Ypnose also came along and reported an issue with IMAP handling
201 that was related to the compatibility credential handling of the new
202 URL and credential layer.
204 (Gavin Troy, Ypnose, Karol Blazewicz) [a5c40ba]
205 [1] <https://bbs.archlinux.org/viewtopic.php?id=182653>
207 - We now also have -HOST and -USER@HOST *smtp-use-starttls*. [bfb186a]
209 - Gabby history entries will now be saved and restored as such, in case
210 *history-gabby-persists* is set. (For this to work properly
211 a possibly existing history file needs to be reset.) [b5502cc]
213 - We now have optional .netrc support (*v15-compat* set).
214 Set *netrc-lookup* and we'll look in $NETRC / ~/.netrc for user
215 credentials. The `netrc' command will show or clear the entry cache.
216 E.g., this is my new account macro:
218 set v15-compat ssl-method=auto
220 set smtp=smtps://smtp.yandex.ru:466 smtp-auth=plain smtp-hostname= \
222 ghost xp 'fi %:pop3s://pop.yandex.ru'
223 ghost xi 'fi %:imaps://imap.yandex.ru'
225 As an extension to the .netrc syntax we support a single
226 introductional subdomain wildcard, e.g., my relevant ~/.netrc entry:
228 machine *.yandex.ru login NAME password PASS
230 Following a suggestion of Gavin Troy we have multi account support,
231 i'm not quite sure wether this is portable across .netrc using
232 applications, e.g., i could have written the above like
234 machine *.yandex.ru login NAME
235 machine *.yandex.ru password PASS
236 machine *.yandex.ru login NAME2
238 (I hope i don't lie and this really works.)
239 (Suggested by Gavin Troy and Ypnose, testing and feedback Gavin Troy)
242 - Add primitive support for RFC 3798 via the new
243 *disposition-notification-send* variable. This is not yet
244 a truly conforming implementation (it simply injects the necessary
245 header) and it requires the *from* variable to be set.
246 More in the far future, sorry. (Wiesław Magusiak) [ca31d32]
248 ChangeLog (purely technical)
249 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
251 - Interrupt protection during (recursive) macro calls with `localopts'
252 on should now no longer be crashable at all. Quote [a4e85c0]
253 It is of course all pretty intermediate until we have a signal
254 manager and we can actually poll signal states at those places where
255 we are capable of and desire to handle them. But it should work
256 today and look nicer than it did.
257 [25caeb9,592499f,a4e85c0]
259 - `ghost' handling performs more strict name checking on ghost names in
260 order not to allow names which would later not be parsed as a whole.
263 - Dropped catopen(3) support (we never really had it)! We will have
264 a new S-nail-specific gettext(3)-alike thing in v14.8.
265 [topic/i-wanna-have-a-dog]
270 Thanks go to Tarqi Kazan (tarqi AT cfs DOT or DOT gs) and Johannes
271 Löthberg (johannes AT kyriasis DOT com), as well as Martin Neitzel.
272 (And the winner is... Gavin Troy for his role in "Silence from Ireland".
278 - Since S-nail now performs more-or-less proper percent-encoding as per
279 RFC 3986 users of *imap-cache* have to (either throw away and recreate
280 or) adjust their local cache, e.g. as follows (adjust CACHEDIR and
281 echo(1) to mv(1) as necessary; won't work with paths with whitespace):
283 $ CACHEDIR=${HOME}/traffic/.mail-cache; \
284 find ${CACHEDIR}/ -depth -type d |
287 r=`echo ${b} | sed -e s/:/%3A/g -e s/@/%40/g`
288 if [ ${b} != ${r} ]; then
290 echo ${d}/${b} ${d}/${r}
297 - New variable *history-gabby* can be set to add much, much entries into
298 the history than is done normally.
299 For the NCL only, setting *history-gabby-persist* will cause those
300 entries to be saved into *NAIL_HISTFILE*, too, which they are not by
301 default with it (the other command line editors should always save).
304 - The `online' alias for `connect' has been obsoleted. [d5cfde4]
306 - New CONFIG=MAXIMAL make option. [c0d4087]
308 - Support compilation on new OpenBSD with their reduced OpenSSL clone.
309 This topic also includes the real solution for getting rid of
310 a strcat(3) warning that i reintroduced with s-nail-14_5_2-smime.patch.
313 - Our -r command line option is now mapped to a `-f' MTA option -- the
314 sendmail(1)-compatible `-r' is long obsoleted! (Johannes Löthberg)
317 - New `elif' command so that we now have if..elif..else..endif.
318 If the optional regular expression support is available the new
319 conditions `=~' and `!~' can be used to perform (case-insensitive)
320 regex matching with `if' and `elif'. [topic/condsplus]
322 - New `~R' tilde escape (like `~r', but indent lines). [fae1f29]
324 - Improved multibyte-safety (e.g. for *prompt*) and a bit of
325 compatibility ("support" would be a wording much too strong) for
326 bidirectional text via the new *headline-bidi* variable.
327 [topic/unibidi, topic/mbbidi]
329 - Diversified behaviour of -v command line option as well as *verbose*
330 to support multiple levels of verbosity; the latter is now ternary
331 when set and boolean when unset.
332 This was the ground on which SSL certificate validition verbosity was
333 implemented (*verbose* level 1: certificates, level 2: network
334 communication et cetera), though much is left to do.
335 This has been suggested long ago by (Martin Neitzel). [topic/smverb]
337 - ^C in compose mode with *ignore* set acts now POSIX compatible
340 - If *encoding* is set to base64 then we don't ignore that user
341 wish and use quoted-printable (when 7bit doesn't suffice) [2ca201f]
343 - New `urldec' and `urlenc' commands. [63e869e, fbd95e8, 0af5b1b]
345 - New `setenv' and `unsetenv' commands. [5e2ed79]
347 - Support for GSS-API authentification has been added (request and
348 testing by Tarqi Kazan).
350 Note that the following implicit relation is gone:
352 If set to `login', or if unset and smtp-auth-user is set, `AUTH
355 This topic branch also added support for the SUBMISSION protocol of
356 RFC 6409, so re-reading the *smtp* manual may bring benefits.
359 - A new, backward-incompatible URL syntax and credential lookup scheme
360 has been introduced that is accessible when the new *v15-compat*
361 variable is set. If used, credential lookup occurs before a network
364 The new manual section "URL syntax" describes the new credential
365 variable chains, and documentation of *from* should be read again, as
366 i now also refers to the new *smtp-hostname* variable.
368 Note that the generated `Message-Id' has also changed.
370 (Messy old way pointed out by Tarqi Kazan)
371 [topic/url, topic/cred]
373 - `resend' should be truly fixed and (fwiw) can also resend to pipe and
374 file addressees. [topic/resend]
376 - Support for empty lines in macro and account definition blocks (as
377 required by POSIX for startup files in general) [43cdf92]
379 - The nail command line editor gained the possibility to use PgUp /
380 PgDown / Home / End instead of z[-+0$] commands on xterm-compatible
381 terminals; and ^O equals a `dp' there, too. [8c57be2, 7c30e61, 95e672f]
386 Many thanks to Gaetan Bisson.
391 - Avoid segmentation faults with -L option if s-nail is opened on
392 non-existent mailboxes, e.g. '$ MAIL= s-nail -Lx'. (Gaetan Bisson)
398 Thanks and greetings to Gavin Troy, Gaetan Bisson and Tarqi Kazan (tarqi
399 AT cfs DOT dyndns DOT biz).
401 ChangeLog (packager-affine)
402 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
404 - WANT_AUTOCC knows that clang(1) version 1 can dig -Wstrict-overflow=5.
407 - '$ make test' should work even if you are not steffen.
408 (Gaetan Bisson, Gaetan Bisson, Gaetan Bisson, Gaetan Bisson,
409 Gavin Troy, Gavin Troy) [8b796ba]
414 - *autoinc* is gone -- this is *newmail*. [07a8462]
416 - Working with large(r) IMAP boxes should work again without causing
417 segmentation violations. (Gavin Troy) [761dd87, b0ce180]
419 - With our builtin getopt a.k.a. WANT_NOGETOPT=1 usage of the -L option
420 caused segmentation violations. (Tarqi Kazan, Gaetan Bisson) [f2c2646]
422 - The decision wether we need $PAGER or not now also incorporates the
423 informational lines we inject for messages. [316b4cd]
425 - Drop `defines', add `unaccount', rename `undefine'..
426 The `defines' command has been united with `define' -- just like
427 `account' will list all defined accounts when used without arguments
428 `define' will now do so for macros. And `undefine' is the new name of
429 `undef'. The new command `unaccount' can be used to delete all given
430 accounts, in equal spirit to `undefine' and macros.
431 All of this is still vulnerable against recursivity, e.g., deleting
432 an executing macro still works, but don't that. [b0b3275]
434 - Rename `var-inspect' to `varshow'; silly oversight that `var-inspect'
435 will try to lookup a variable "-inspect". Ouch. [afffd30]
437 - Without HAVE_ICONV the character set iterator sofar used
438 *charset-8bit* as the last resort, whereas it should have used
440 P.S.: All this still preliminary, we await the MIME and send layer
441 rewrite to calm down the stuff for real. [edc3226, df9aefd]
443 - During `~@' editing it is possible to leave the possibly endless
444 character set selection loop by interrupting via ^C.
445 In the meanwhile this effectively drops the currently edited
446 attachment and leaves the entire attachment selection session; it
447 doesn't make sense to make it any better until we have our signal
448 manager and stop jumping around.
450 This changeset should also fix dangling Content-Xy MIME information of
451 attachments which were in the same slot before, e.g., if #1 was
452 a message attachment and that was changed on-the-fly to be a real file
453 attachment then the Content-Description would still have stated that
454 it is a message attachment.
457 ChangeLog (purely technical)
458 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
460 - Since it has been decided to remain compatible to ISO C89 we cannot
461 use the ISO C99 `z' format string modifier (printf(3)).
462 Since quite some time we make efforts to provide our own `ZFMT' macro
463 (in `nail.h') which provides somethint compatible, but on 32-bit
464 platforms compilers often complain nonetheless.
465 Therefore we now also have a compile-time assertion that proves that
466 our `ZFMT' macro is really correct. [397e4d1]
471 Many thanks to the perpetual Gavin Troy.
473 - Faulty notational change of system call return values from `<0' to
474 `==-1' caused endless waitpid(2) loop. [d6f316a; test(!): 79fd761]
477 - (GLibC) STD I/O overoptimizes rewind(3) so that underlaying file
478 descriptor offset is not reset to 0. Generalize the already
479 used `really_rewind()' hack and use it not only in
480 `savedeadletter()' but also in `page_or_print()'. It is likely
481 that this not also fixes `history' listing but also some other
482 things which go through the pager, dependend on the setting of
483 *crt* etc., and on at least GNU/Linux systems. [463660f]
485 Note: standard I/O does NOT offer a possibility to do this in
486 a non-hackish way. It is thus likely that S-nail will gain
487 a completely new I/O layer in the future. That'll also be faster.
490 This note is false: POSIX Issue 7 overloaded the meaning of
491 fflush(3): when used on readable streams the file offset of the
492 underlaying file descriptor is adjusted to that of the stream.
493 (nail.h: adjust really_rewind(): POSIX Issue 7 defined a way..)
494 uses this official approach instead if _POSIX_VERSION>=200809L.
496 - Old shells will now correctly execute an error-condition
497 execution path in `mk-conf.sh'. [afef55f]
502 Thanks to Andy Switala (andy DOT switala AT gmail DOT com).
503 And thanks to all package maintainers for their stamina.
505 At the first workday after the release i've run into a bug that was
506 caused by an oversight, a double-Fclose() that would be harmless if we
507 wouldn't forcefully panic() when we encounter it!
509 So i've spent another week on a review, and despite fixing many
510 additional notational oversights i haven't found more oversights of
511 newly introduced problems. On the other hand i've found and fixed some
512 old problems during the review, and tweaked some other things:
514 - The INSTALL file now has a `Current codebase state' section.
516 - Commands invoked via `!' should now be interruptable.
517 I'm afraid the exit status of such a command will not be reflected by
518 the return value of the `!' command yet, but hey, at least `!sleep 10'
519 can now be interrupted -- try this with another Berkeley Mail!
522 - All credential prompts should now be interruptable.
523 (Inspired from Andy Switala) [c3bb2a2]
525 - 'make test' will now test a silly S/MIME case when WANT_DEBUG (or
526 'make devel') was used. [8cff17f]
528 - *batch-exit-on-error* should now look at the exit status of *every*
529 command when the command loop ticks. [c7e7d53]
531 - The new `[?name-list]?search-pattern' search expression has been
532 changed to `[@name-list]@search-pattern' -- like this it doesn't clash
533 with the `?' help command and can thus be used on a line by itself,
534 causing the default command (`next') to be invoked on its' result,
535 shall there be one. Ok, yes, that was surely also an oversight.
538 - *attrlist* must now be exactly 13 characters, just as it should
539 be. An error message is printed if not. It was always komisch,
540 but i'd buggified it somewhen in the past. Now fixed.
543 - The NCL WANT_TABEXPAND feature now also works if *newfolders* is
544 set to `maildir'. Yet, if a folder was assumed to be of maildir
545 type, shell globbing would not occur. [part of f5c184c]
547 - The `X-Decoding-Data' S/MIME header field was set to the epoch
548 origin instead of NOW in v14.6.
550 Also the `certsave' command now supports file globbing (i.e.,
551 '~/.certs/' should end up in your $HOME now).
552 [both part of 7e0aec7]
557 + With this release the S-nail codebase has been converted to my usual
558 style of function-code-flow and notation.

565 Maildir and S/MIME support have been restored, and a MIME bug that
566 could have led to missing data in header display+ has been fixed.
567 Ah, and users of compressed boxes should now feel luckier, too --
568 at least once they've realized that the compress extension is no
569 longer appended automatically, but must be given explicitly.
571 Thus: i hope that all those i-am-new-to-the-codebase bugs i've
572 introduced over a year ago have been found and fixed, and that
573 v14.6 is the true "sweet sixteen" (months of maintainership).
575 ChangeLog (packager-affine)
576 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
578 - If WANT_AMALGAMATION is set, `-pipe' will be added to our CFLAGS
579 (which are only honoured with WANT_AUTOCC, of course). [1330411]
581 - New configuration option: WANT_IMAP_SEARCH, enabled by default.
583 The regular expression support for IMAP-style search expressions has
584 been removed again: it changed the IMAP search semantic in that it
585 couldn't be executed on the server, but only local, and the syntax
586 sucked, too. (And we have a new `?' search expression.) [402b7c6]
588 - CONFIG=MEDIUM and CONFIG=NETSEND now both WANT_REGEX. [dee954e]
590 - The `make test' target should *really* work gracefully, now that usage
591 of the `-#' command line option also sets the folder to be opened to
592 `/dev/null'. (Still no `void' box in sight.) [0119d514]
594 - All published patches may also be found in a new [patches] branch.
599 - Several fixes that saw published patches (with equivalent
600 functionality), and are thus described in NEWS, are included:
602 . s-nail-14.5.2-sort-alt.patch
603 Fixes a hasty commit that introduced string relaxation in a faulty
606 . s-nail-14_5_2-mimeheader.patch
607 Fixes data loss if multiple MIME encoded-words follow each other in
608 header bodies. [c81afce]
610 . s-nail-14_5_2-maildir.patch
611 Effectively restores proper maildir support. [1c2563b, 13f325f]
613 . s-nail-14_5_2-smime.patch
614 Fixes an off-by-one error and, in effect, restores S/MIME sign and
615 encryption etc. support. [e759f75]
617 - The `screen' terminal type is by default recognized as being
618 colour-capable. [e759f75]
620 - With the NCL command line editor and WANT_TABEXPAND hitting <TAB>
621 should now act as if an "implicit asterisk" had been given in case
622 there was no expansion of the original user input; e.g., '? ls <TAB>'
623 may exceed your line limit now ;). [0910a8f]
625 - The S/MIME cipher list was outdated, RFC 5751 requires AES-128 as
626 the default, the RC2 ones are long obsoleted (etc.). Also we now
627 should handle that OpenSSL may not support individual algorithms.
629 Note: we use the option value `des3' for `DES EDE3' from now on!
630 (Maybe see *smime-cipher-user@host* manual entry.)
632 *ssl-method* may now also be assigned the new (default) method `auto'
636 - Messages will now be stored in a set *record* even if only file or
637 pipe addressees were given. [a11935b]
639 - Support for xz(1) compressed mailboxes has been added.
640 (The `Can't canonicalize' warning for compressed boxes had the same
641 cause that made maildir usage impossible, but i don't feel _too_ bad
642 because looking into the code a bit revealed that the *newmail*
643 mechanism never worked for such boxes anyway. And will for a while.)
646 - S-nail now supports nested if..else..endif conditionals. [3c22c04]
648 - The NCL command line editor now locks its' history file when it reads
649 and writes it, so as to protect against concurrent usage. [c3a39ce]
651 - You can now say 'fi%', 'fi&', 'p&10' and `ghost ps '!ps axu'' followed
652 by 'ps|grep nail'. [c3266c6]
654 - Invocation cleanup: usage of -f and -u is mutual, -H and -u is ok, -u
655 in send mode not. [fa0a0aa]
657 - New message specification: `[?name-list]?search-string' will search
658 in locally available messages. If the optional `?name-list' part is
659 given, that specifies the (comma-separated list of) header fields to
660 search in. The special names `body' and `text' can be used to search
661 in message bodies alone and bodies including the headers fields,
662 respectively. Note that "message bodies" unfortunately still means
663 "including headers of attachments and attachments themselves", and
664 until some later time. [61bb460]
666 - The new command line option `-L spec-list' prints a header summary of
667 only those messages that comply to the specification list `spec-list'.
668 If -L and -H are used in combination, no summary is printed at all,
669 but the exit status reports wether `spec-list' would have matched some
670 messages or not. [934e12c]
672 ChangeLog (purely technical)
673 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
675 - Most of the work was changing the code-flow of the entire codebase to
676 my usual style of programming, with a single function entry and
677 a single function exit, including the addition of N(ot) Y(et) D(ead)
678 points of interest, which finally enabled me to get rid of (sic!)
679 using a debugger for S-nail development. Just compile via 'make
680 devel', and in case of a crash you should get a nice backtrace
681 listing. (You use IMAP, do you?)
683 However, because practically every line of code has been touched, this
684 caused some other changes along the way, e.g., the handling of
685 temporary files was changed completely (the formerly used Ftemp()
686 function has been replaced with a new Ftmp(), which handles unlinking
687 itself as necessary etc.), it was detected that the S/MIME support was
688 no longer compliant to any RFC, some resource leaks have been
689 eliminated... It is likely that a change so large introduced some
690 other flees and flaws, however. But it looks good so far.
696 + No official release, only exists as git(1) tag.
698 v14.5.2: fix 4: 2014-02-15 (2014-02-14)
699 ---------------------------------------
701 - s-nail-14_5_2-smime.patch
702 Fix a very stupid off-by-one error that i've introduced
703 in [7bdf330] (OpenBSD 5.3: sigh, address strcpy(),strcat()
705 Until we've changed the used data from string to something
706 line-wise, use strcat(3) again.
708 v14.5.2: fix 3: 2014-02-10
709 --------------------------
711 - s-nail-14_5_2-maildir.patch
712 maildir folders would have caused problems in environments which
713 provide the realpath(3) function: beside a "cannot canonicalize PATH"
714 warning the finally used path would be wrong (`test3' would end up as
715 `test3/test3'), so that any further access would try to use the wrong
716 path. Please read the description of this patch and/or the commit
717 logs of the commits [1c2563b] and [13f325f].
719 v14.5.2: fix 2: 2014-02-05
720 --------------------------
722 - s-nail-14_5_2-mimeheader.patch
725 Subject: ehm, .getElementById("blink") needs <span
726 =?US-ASCII?Q?id=3D"blink">,?= not =?US-ASCII?Q?class=3D"id"?=
728 would yet be displayed without the " not " in between the two encoded
729 words because of faulty "encoded-word-continuation" detection (note
730 the quotation marks). The error path could also have been seen in
731 mail forwarding and in faulty searching etc.
732 This patch is in a row of fixes for my hasty [0f9ad93] from 2013-03-12
733 that already caused the v14.2 minor release (because of [b608c6b] from
734 2013-03-14). Those with mercy may read the commit message of [c81afce].
736 v14.5.2: fix 1: 2014-01-30
737 --------------------------
739 - s-nail-14_5_2-sort.patch
740 Reverses (sort(),thread(): use srelax()!, 2014-01-18, [a9b67e9]),
741 which was a hasty commit of an untested diff that i've added few
744 As a rather careless last-minute change i've added string relaxation
745 to threaded and sorted display, but it's really one more step towards
746 lowering memory pressure -- i couldn't resist [a9b67e9] after seeing
748 An alternative, forward-heading patch that keeps string relaxation has
749 been pushed to [master] as [5e75529] and is also available as
750 s-nail-14_5_2-sort-alt.patch.
755 Thanks to Ypnose, Sunil Nimmagadda and Gavin Troy.
756 Gavin Troy *really* deserves special thanks for facing [next]!
757 And i want to dedicate the new coloured message display functionality
758 to John Dodson and Ypnose. Thank you.
759 (And best wishes to beautiful Australia!)
761 ChangeLog (packager-affine)
762 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
764 - All utilities can now be overwritten during configuration so that
765 their values are fixated in the generated makefile (`mk.mk').
766 I.e., talking about MAKE=, STRIP=, awk=, cat=, chmod=, cp=, cmp=,
767 grep=, mkdir=, mv=, tee=.
768 rm= and sed= have to be overwritten from the command line, they're
769 needed before `conf.rc' is read.
770 [5c03347, 072ec65, 39a00ab, 23a1245, ?]
773 - The release tarball is now also available in a xz(1) version.
775 - New configuration option: WANT_COLOUR, by default enabled.
777 - 'make test' should now really work, even if the running user has
778 a mailbox with content. [f223a91]
780 - WANT_AUTOCC is now by default enabled, so as for normal users which
781 don't have the need to embed into a defined packaging environment.
784 - Installation no longer strip(1)s away debug symbols if WANT_DEBUG was
791 - Fixes to some bugs that are present since the first cvs(1) commit of
792 Heirloom mailx(1); includes that *ssl-key-user@host* should now work.
793 [4405a2cc, 9770c26f, 692976b9]
795 - Some off-by-XY fixes, thanks to the debug memory canaries.
796 [19b2b0d, 202506e, 43df6e4]
798 - Fixes for (other) stupidisms (of mine): [1c2161f]
800 This includes true implementation of in-memory history limit for the
801 NCL, which was the final and real solution to a segmentation fault
802 that Gavin Troy had to deal with on [next]. [1089f2b]
805 - For completeness: new command `var-inspect' shows information about
806 all given options. Mostly ment for implementing future tests.
809 - The `pipe' command no longer embeds message information into the
810 data passed through to the command (when *piperaw* is set).
811 [ef5ecc6 (part of topic/colour)]
813 - Simple coloured message (header) display is now possible. Please
814 read the new manual section "Coloured message display", use
815 *colour-disable* to turn it off. (It is enabled by default if it
816 knows the terminal is capable and, if used, the pager can, too. Note
817 we now set LESS=FRXi when starting PAGER and no LESS= is in the
820 Dedicated to John Dodson and Ypnose.
821 [topic/colour, c6e84c7]
823 - The `if', `else', `endif' syntax has been extended.
824 You can now "if 0" (never), "if 1" (always), "if $OPTION" (boolean
825 check for OPTION) and "if $OPTION == 'VALUE'" as well as "if $OPTION
826 != 'VALUE'". Unfortunately it is still not possible to use
827 conditionals inside conditionals. [0fb2ae7]
829 - -# now also sets MBOX=/dev/null. [4be2f1e]
831 - The NCL command line editor now supports cursor keys when the terminal
832 produces xterm(1)-compatible keycodes ('ESC' + '[' + [DACB] for left,
833 up, right and down, respectively). What a thrill, yay!!! [0cbf672]
835 - New (optional) command: `history': show or clear command line history,
836 or select a specific command line from in there.
837 History works a bit different now, and should no longer include
838 command lines which include specific message numbers; more to come.
839 [59c6195, topic/hist2]
841 I plan to join all the history management and use only the one that is
842 part of NCL now, hooking it into editline(3) and readline(3). That
843 would shrink tty.c a bit and also introduce duplicate elimination for
846 - The new ~u and ~U tilde escapes work like ~f and ~m, respectively, but
847 don't include any header lines. Inspired by a patch from
848 Sunil Nimmagadda on openbsd-tech@. [c37b8b3]
850 - The `|' command should work again -- it has stopped working on
851 2013-09-09 when i've accidentally changed the command name from `|' to
855 - As a rather careless last-minute change i've added string relaxation
856 to threaded and sorted display, but it's really one more step towards

867 ChangeLog (purely technical)
868 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
870 - We now have debug canaries for all memory sources now that [8419d44]
871 added them to the "string dope".
873 - The most work has been done on our value system, which manages the
874 binary and value options, like *folder* etc.
875 It is now based on enumerations, i.e., constant integers, not on
876 strings. This of course only relates to non-dynamic options.
877 Anyway, this saves us key hashing and allows more compact data
878 representation in general (see the new header `okeys.h' for more).
884 ChangeLog (packager-affine)
885 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
887 - The build system *only* uses the automatically detected $CFLAGS and
888 $LDFLAGS if WANT_AUTOCC=1. I.e., even unset or empty $CFLAGS and
889 $LDFLAGS are not touched until then.
890 (We do however still set $CC if that is unset or empty or set to the
891 plain string "cc".) [856625f6]
896 - Fixed segmentation faults / bus errors when setting *nofolder*
897 / *line-editor-cursor-right* to the null string (only with WANT_NCL),
898 respectively. [d1f1a19b, 21e5c285, 9f6ff25d]
900 - *prompt* handling is now really POSIX compliant (thus no prompting
901 occurs not only for 'set noprompt', but also for setting *prompt* to
904 This was indeed a rather large changeset that also introduced the new
905 *prompt* escape character \&, which expands to `?' by default and to
906 `&' if *bsdcompat* is set.
908 Like that we now can simply assign "\& " to *prompt* at program
909 startup, which (a) allows to do 'set noprompt' without error (once)
910 and (b) allows for POSIX compliance in respect to prompt handling
911 without any complicated conditional code, but (c) gives us the
912 opportunity to continue to support BSD prompts.
915 - For completeness: new command: `features'. (Rather useful for being
916 able to implement more tests in the future, and act according to what
917 is really compiled into the tested binary.
919 - The `-#' command line option now also sets *quiet* by itself.
922 - nail.1: a newly introduced empty line in the manual produced error
923 messages on some systems. Fixed.
925 - The return value of the `mimetypes' command has been reversed and
926 should now be fixed. [acf56ac52]
928 - In threaded display the Subject: followup suppression no longer
929 takes into account invisible messages.
930 Also, rudely hack in a messages-already-written-in-this-round counter,
931 so that the followup suppression knows when "the top of the screen" is
932 reached, which (seems to) help(s) against missing subjects up there as
933 well as after a `newmail'. [topic/subject]
935 - Added a WANT_REGEX=1 toggle in `conf.rc'.
936 When we find regular expressions then a new regex-enabled IMAP-style
937 search is available (see the manual for more) [1ec8fe68]
939 ? f (/or subject ^\[S-nail (subject ^\[nail-devel))
940 ? f (/subject ^\[S-nail) (/subject ^\[nail-devel)
941 ? f (/subject "^\\[(S-nail|nail-devel)")
943 I'm looking forward for being able to add another, simplified, syntax.
945 ChangeLog (purely technical)
946 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
948 - The cc-test.sh has seen some tweaks, for easier future extension, and
949 for adding a test for [d1f1a19]. [several, mentioned: 21e5c285]
951 - On systems without a real wordexp(3) implementations deadlocks could
952 occur because we sometimes hold_all_sigs() to avoid longjmp(3)s away
953 (and will do so for quite some time, still), and that resulted in the
954 SIGCHLD that reported the exit of the started subshell to be blocked,
955 too (e.g., after '? *.h<Tab>': endless hang). Fixed.
960 Many thanks: Gaetan Bisson, William Yodlowsky, Gavin Troy,
961 Thomas (wasd AT gmx DOT net), Ypnose.
962 And Gavin Troy definetely deserves a very special credit.
963 But thank you all, and very much indeed!
965 ChangeLog (packager-affine)
966 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
968 - The `test' make target has been fixed. [f0991e14]
971 - It is possible to gain a different kind of make(1) verbosity by
972 using a VERBOSE=1 command line argument (this knob is not taken into
973 account when deciding wether a rebuild is needed). [498e4ad0]
976 - On Crux 3 Linux and OpenBSD the readline(3) and editline(3),
977 respectively, libraries will now be found when desired. [a7d1aa78]
980 - WANT_LINE_EDITOR has been renamed to WANT_NCL, *plus*.
981 So now there are WANT_READLINE, WANT_EDITLINE and WANT_NLC, each of
982 them can be set individually, and they are tested in the shown order.
983 Also, WANT_TABEXPAND and WANT_HISTORY have been introduced and can be
984 used to fine-tune functionality. [ae4e01e1, b2635feb, 9742bf40]
986 (While here, i've fixed WANT_TABEXPAND code so that it is more
987 sensitive to line excess; on Linux etc., where MAX_INPUT is 255,
988 strange behaviour could be seen because we didn't take into account
989 the length of the prompt at all. The NCL is assumed to have only
990 one remaining, but unfixable problem: backspace often is incapable
991 to cross visual line boundaries; use ^A/^E + ^L, then. [e832c04a]
993 Also, cursor (now ^B and ^F) and history movement (now ^P and ^N) of
994 the NCL have been changed. [d7d928da])
996 - WANT_QUOTE_FOLD is now enabled by default. And WANT_ASSERTS has been
997 renamed to WANT_DEBUG. [1e10da1f]
999 - The build system has seen yet another overhaul in general. CC, CFLAGS
1000 and LDFLAGS plus are now tracked and changes will force rebuilds.
1001 The new WANT_AUTOCC option can be used to let the build system figure
1002 out a compiler and choose known-to-work flags. Use the new ADDCFLAGS=
1003 and ADDLDFLAGS= command line arguments to add your specific flags on
1004 top of those -- the final CFLAGS etc. are what is change-tracked.
1006 This rather massive internal rework revealed that old Bourne shells
1007 were yet not supported by the new build system, and so did testing
1008 that UnixWare installation was yet impossible due to tool
1009 incompatibility. [75c4b74e]
1011 - The new WANT_AMALGAMATION option will force compilation of all the
1012 sources in a single compilation unit. This requires a rather large
1013 amount of memory, but may produce a more compact, maybe more optimized
1014 binary. (Implementing this revealed quite some bugs which could
1015 therefore be fixed.) [topic/amalgam]
1017 - `nail.rc' has been pimped a bit (mostly comments, but
1018 *mime-counter-evidence* is now always set). [e3094ba7]
1020 That changeset was however buggy. [f3dcb46]
1023 - We no longer use install(1) for `install'ation make rules. [80b02cd9]
1028 - Even '$ s-nail & fg $!' will now work with the NCL. [2a8b5c55]
1030 - Several off-by-one (off-by-two) fixes. [32ce9836, 71e6d013, f139dc36]
1031 (Gavin Troy, Thomas)
1033 - Setting *noprompt* now prevents prompting, as per POSIX. [ecefaf63]
1035 - *prompt*: new \$ (exit status of last command) and \@ (name of
1036 currently active mailbox) escape sequences. [6f652046]
1038 - One may now omit the space in '? unc' ('?unc') [05fcb383]
1040 - New commands: `ghost' and `unghost' define command aliases (since
1041 `alias' is taken for a different purpose) [topic/commands]
1043 ? ghost ps '!ps axu'
1046 - There is now a pseudo account `null' (case-insensitive).
1047 Also a new `localopts' command exists; when used from within an
1048 `account' block, options changed will be reverted back to its former
1049 value when the account is left (e.g. by switching to `null'):
1052 alternates sdaoden@users.sf.net sdaoden@users.sourceforge.net \
1053 sdaoden@googlemail.com sdaoden@gmail.com
1054 set Sign="\n--steffen\nForza Figa!" sign="\n--steffen"
1055 set smtp=smtp.gmail.com smtp-auth=plain smtp-use-starttls
1061 set from="Steffen \"Daode\" Nurpmeso <sdaoden@gmail.com>"
1066 set from="Steffen \"Daode\" Nurpmeso <sdaoden@users.sf.net>"
1074 neither of *Sign*, *sign*, *smtp** nor *from* should be set.
1075 Please see the manual for more.
1076 TODO - neither command-ghosts nor alternates etc. are yet tracked
1077 TODO - we should have a boolify() so as to say 'localopts yes' etc.
1080 - New command: `cwd' (print current working directory).
1081 Also fixing the `chdir' return value. [eff4397c]
1083 - The *ssl-method* now allows explicit setting of 'tls.1.1' and
1084 'tls1.2' values. [c66b4196]
1086 - When sending to display, be aware that filenames in MIME parts may of
1087 course be MIME-encoded! [1454be03]
1089 - *hostname* is now honoured even if *smtp* is not set. (We always
1090 supported *from*, so why not *hostname*?)
1092 - The `-u user' option now acts identically to setting the $USER
1093 environment variable and both now tend to mean something like
1094 "impersonate as user in some aspects". Note that we have always used
1095 the latter in one or the other way, and `-u user' always ment more
1096 than just "open mailbox of user", so i think this change sharpens the
1097 edge in the right direction. [09632731]
1099 - Filename argument quoting has been tweaked for (some) function(s which
1100 take a filename argument last). The following snippet as reported by
1101 Gavin Troy should work now: [2bb9b80e]
1103 ? mv +inbox.Junk\ Mail
1105 - The GNU implementation of wordexp(3) is also (i've added a workaround
1106 for the very same bug for Mac OS X in S-nail v14.3 [63273772]) buggy,
1107 which causes segmentation faults when expansions failed (`fi &VOID').
1111 - The `fi' command no longer uses the (possibly truncated) display
1112 version of a filename, but the full path. [5cd85b07]
1114 ChangeLog (purely technical)
1115 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1117 - Large rework of internal structure: bundle inclusion of most of the
1118 external and the content of most of the internal #include files in the
1119 new nail.h. If that would have been done very first bugs like the
1120 infamous MAXPATHLEN bug as reported by Paul Vojta (see v14.4.2) would
1121 never have occurred. [21f3155b]
1123 - Support for -fstrict-overflow cc(1) flags. [topic/strict-overflow]
1125 - Fixed the quotation filter which yet allocated memory even if not
1128 - String relaxation reduces memory pressure rather drastically when
1129 working with many (especially MIME) mails at a time, e.g., when
1130 writing a modified mailbox. Before all messages of a mailbox had to
1131 be worked without releasing any memory in between, now we give back
1132 memory (to our pool, not the system) after each and every message.
1135 - The other memory source now uses bound canaries, which also found some
1138 - We now use the EL_PROMPT_ESC editline(3) mode for prompting, which
1139 should offer the possibility to use coloured prompts etc. with
1140 (even those) editline(3) (versions which do offer it -- older versions
1141 should just do fine by themselves).
1142 S-nail uses the special trigger control character \1. [ea30d818]
1145 Note however that all tested editline(3) versions are buggy and
1146 either don't get it right (`\1COLOR-ON\1stuff\1COLOR-OFF\1') or are
1147 incapable of proper repainting (`\1COLOR-ONstuffCOLOR-OFF\1').
1149 - We now use the MD5 digest code from the OpenSSL library if that is
1155 Many thanks: Gaetan Bisson, Stephen Isard, Jérémie Courrèges-Anglas,
1156 William Yodlowsky, and Adam Sjøgren from GMANE.org!
1158 ChangeLog (packager-affine)
1159 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
1161 - The packager-install: target has been fixed. [a8c1b0b]
1162 (Gaetan Bisson and William Yodlowsky)
1164 - As suggested by Gaetan Bisson the several build system tasks are now
1165 individually addressable, i.e., 'make [OPTIONS] config', 'make build',
1166 'make test', 'make packager-install'); nothing changes unless you want
1167 to, in which case: please see INSTALL. [4d3b799]
1169 The new target 'test' will call cc-test.sh with its new --check-only
1170 option which will only perform the (too few) function tests on the
1172 And cc-test.sh will no longer create output files, but simply echoes
1173 to STDOUT and STDERR. [629e1ee, 786f219]
1176 - The default configuration file now sets *bsdannounce* and *bsdflags*,
1177 all in one line, as suggested by William Yodlowsky.
1178 (If *header* is disabled, *bsdannounce* is ignored, but *header* must
1179 be enabled by default according to POSIX, and *bsdannounce* is just
1180 the same as *header*, but for the folder-switched event. Thus setting
1181 *bsdannounce* is the more sane default, imho.) [6161f10]
1184 - Announcement messages are now tagged '[ANNOUNCE]'. [26e1b35]
1185 (Tagging suggested by Stephen Isard and Jérémie Courrèges-Anglas)
1187 - The manual NAME now includes the version (but it's somewhat ugly).
1193 - When switching folders when in compose mode, message attachments
1194 become invalid. For v14.4.5, at least warn when this happens.
1197 - When reading multipart/alternative messages which do not contain
1198 a text/plain part, the (most likely HTML) part is not displayed (even
1199 if S-nail is configured to display HTML). The reason is a bug i've
1200 introduced with [0d43a999] (Change "Part X:" display message..,
1201 2012-12-20). (Note that the committed fix i've posted to the list was
1202 not correct either and has been fixed itself.) [225c02b, ecfa149]
1207 Thanked, Gavin Troy, Gaetan Bisson.
1209 - Fix output buffer confusion that would have occurred when parts of
1210 a multipart mail had a pipe command set. Longer story in [e75d16dd].
1213 - The makefile now supports a `packager-install' target that bypasses
1214 the reevaluation of the configuration (after checking that there is
1215 one) and directly steps ahead to the install process.
1218 - Notes in INSTALL that CFLAGS and LDFLAGS need to be overwritten from
1219 within (conf.rc or) the command line.
1225 I convey special thanks to Karol Błażewicz and Gaetan Bisson.
1227 - The new build system didn't allow to overwrite CFLAGS= when used in
1228 conjunction with GNU make(1). To make a long story short, removing
1229 a `.POSIX:' directive from the makefile fixed the problem. Luckily.
1232 - More INSTALL notes for UnixWare 7.1.4, which suffers from the same
1233 problem: here the fix is to use the -e option of make(1).
1235 - Karol Błażewicz reported a segmentation violation he got when using an
1236 Arch Linux S-nail test package, and Gaetan Bisson informed me about
1237 that. The problem was that we didn't assign the resulting default
1238 address (which gets used when *from* is not set) to the result which
1239 gets used, effectively resulting in a NULL dereference. [cfd60479]
1244 Many thanks to Paul Vojta.
1246 - On GNU/Linux there is no MAXPATHLEN constant defined by default, as
1247 this is a non-standard legacy constant. Mozilla ran into this some
1248 time ago, though a bit different [1]. It made it easier for S-nail.
1250 [1] <https://bugzilla.mozilla.org/show_bug.cgi?id=412610>
1252 We could include `sys/limits.h' to get at MAXPATHLEN, there it is
1253 defined to be PATH_MAX, but let's just include the standard `limits.h'
1254 and ensure MAXPATHLEN ends up >= PATH_MAX. With this condition being
1255 true even FORTIFYd sources won't bail with reported buffer overflows
1256 because realpath(3) expects a buffer of PATH_MAX bytes. [bee5e57c]
1259 - With the builtin LINE_EDITOR, ensure proper interaction with GNU
1260 rlogind(8), which is alone in its quest to set the ISTRIP termios(4)
1263 - Bugfix a codepath that would have prevented compilation when
1264 HAVE_ICONV is not set.
1265 While there, allow to unselect message attachments when using the `~@'
1266 tilde command interactively, which i mysteriously had forgotten when
1267 allowing selection of 'em. (oops?) [4f58ffea]
1269 - It's now easier for packagers to get at debug-enabled CFLAGS; simply
1270 use WANT_ASSERTS=1 (should not be enabled in shipouts, please).
1273 - Fixed a terrible bug that i've introduced in november 2012, that would
1274 have corrupted MBOX files when using the `resend' command. (The
1275 so-called "From_ line" would have been quoted to ">From_ line" instead
1276 of simply being stripped.) [19d449e2]
1278 - Fixed a SIGSEGV for the builtin LINE_EDITOR, that would have occurred
1279 if a history traversal (^B or ^F) would have been continued by
1280 a reverse history completion (^R).
1281 While there, avoid some multiple-beeps-in-a-row that yet occurred due
1282 to code reuse, and document that ^G etc. reset the multibyte state
1285 Also, the expand-on-tab code could have excessed line input maximums,
1286 e.g., after `? /usr/bin/*<Tab>'. This was of course known, but
1287 i wanted to keep it because all tested (modern) terminals "mess up but
1288 won't break", and thus made it possible to use the data, even if it's
1289 visual representation was messed up. The real solution will be much,
1290 *much* more complicated, i.e., show possible *completions*, page-wise,
1291 etc., i.e., just like is known by tab *completion*. This will need
1292 far more time because it doesn't make sense to embed such complicated
1293 code into the current bed.
1294 Now i've chosen to simply don't display excess, but replace the
1295 content with a message that says that there was excess. It simply
1296 looks better. [0320c8ba]
1298 - I've changed the use of `[?]' as a replacement sequence for invalid
1299 / non-displayable characters to `?' (again). There are still code
1300 paths (from the original codebase) which use the real Unicode
1301 replacement character instead, so our display is still not unique.
1302 On the long term the codepath can anticipate in all levels wether
1303 use of Unicode is possible, so that, then, we will be unique again,
1304 using either only `?' or the Unicode replacement character. [faf6380]
1306 - I've anticipated in v15.0 and implemented *quote-fold* as a stream
1307 filter. It is now multibyte safe and takes into account the visual
1308 width of characters, i.e., ideographs etc. It is working almost as
1309 good as an algorithm can work that looks at data linewise, but is yet
1310 experimental and incomplete in that it will break lines even if only
1311 whitespace or a backslash escape follows. It is code that is only
1312 a few hours old, which is why it is not enabled by default. [
1319 - Fix some harmless stylos and typos in the manual and `conf.rc'.
1322 - Ensure *complete* proper cleanup on signal-caused configuration run
1325 - Bugfix: reenable empty configuration variable overrides, as in
1327 $ make install SID= NAIL=mailx ...
1330 - Bugfix: rename the `conf.rc' variables SHELL, LISTER and PAGER because
1331 they clash with the POSIX standard variables of the same names, which
1332 hurts now that the configuration is run through the shell itself.
1333 The configuration names are now XSHELL, XLISTER and XPAGER (ouch).
1336 - nail.rc: comment out some non-portable S-nail(1) specifics, for those
1337 who install this file as mailx.rc or so, somewhere. [3f14b01]
1339 - From now on S-nail will use simple version tags, as, e.g., `14.4.1',
1340 i.e., no more `s-nail-14.4.1'. [a75437d, 183d59c] (Jürgen Daubert)
1342 Also move UAGENT out of `version.h' [f7be5be]
1344 Uh! v14.4 must have originated in a bad dream; good it's vanished.
1349 Thanks to the entire vivid and virile S-nail(1) user community is
1350 proper, especially Stephen Isard, Gavin Troy, Martin Neitzel.
1351 Not to forget Ryan Kavanagh and Ayan George.
1353 Note this time the changes are in reverse order, i.e., oldest first.

1371 Slightly tweaked message thread display, fix `:u :r' to mean it
1376 - The default PAGER is now more(1). (But read on.)
1378 - The `echo' command is now compliant, and fully supports XSI.
1380 - The `group' and `ungroup' command aliases have been removed, they are
1381 `alias' and `unalias'.
1383 - We now have the capability of line editing and history.
1384 One may choose from not less than three different implementations:
1385 a builtin editor as well as possible linkage against BSD editline(3)
1386 and also a GNU readline(3) compatible layer.
1387 Please read the new manual section `Line editor'.
1389 Input is now compliant in that an interactive line may be continued
1390 after escaping the newline character with a backslash.
1391 [topic/cledit1] (all of them)
1393 The *prompt* variable may now contain shell escapes, just like the
1394 `echo' command. [0938d8a]
1395 As a special extension the new \? escape, when used within *prompt*,
1396 will expand to the exit status of the last command. [41076d2]
1398 - The POSIX standard environment variables $COLUMNS and $LINES are now
1399 honoured upon startup. [topic/termsize]
1401 - The `help' / `?' commands now support abbreviation, i.e.,
1402 ``$ ? unc'' should now find `uncollapse'. [7b86195]
1404 - The `~' abbreviation that has been introduced as an alias for `call'
1405 is now a real command, not a magic shortcut. [9987289]
1407 - The new variable *quote-as-attachment* can be used to additionally
1408 embed the quoted message as a `message/rfc822' MIME attachment.
1411 - The compose-mode command `~@' will now attach messages from the
1412 current mailbox if given a filename of the style `#NUMBER'.
1413 Please read the corresponding manual section `Tilde escapes', though.
1415 - The `WANT_JUNK' and `WANT_SCORE', as well as Gunnar Ritters junk mail
1416 management have been removed.
1418 Instead S-nail(1) can now support interaction with SpamAssassin, but
1419 sofar only via the spamc(1) / spamd(1) client / server pair of
1420 programs that ships as part of SpamAssassin. The new configuration
1421 directive `WANT_SPAM' controls wether this feature is desired.
1423 Please read the new manual section `Handling spam'.
1424 [topic/spam1] (Martin Neitzel)
1426 (S-nail(1) is now *definitely* floating-point free.)
1428 - The configuration and make system have been overhauled / reorganized.
1429 The configuration is now in `conf.rc', also contains directives like
1430 `PREFIX' etc, and is always read in. However, only those directives
1431 which are not yet set (via environment or command line overwrites) are
1432 incorporated into the set of configuration options. Therefore
1437 will now build S-nail(1) twice, because of the changed configuration.
1439 Note that `WANT_GSSAPI' is now by default disabled, which shrunk
1440 a freshly started s-nail image by more than 30 percent.
1442 We're not finished yet in that there is no dependency graph etc.
1443 Please do read `INSTALL' and `conf.rc'.
1446 - Message selection has been slightly bugfixed in that `:u :r' really
1447 means `:u' AND `:r'. Compared to NetBSD Mail(1) it's still a shame.
1449 Threaded message display has been slightly changed in that within
1450 a thread identical Subject: lines are not repeated. It may not be
1451 perfect yet due to the general list / thread state. [topic/list1]
1453 - If, upon startup, the environment variable `NAIL_NO_SYSTEM_RC' is set,
1454 then the system wide initialization file isn't read, just as if the
1455 `-n' option had been given. [1b31535]
1457 - It is now possible to use CTRL-C during connection hangs. (But in
1458 general error recovery capabilities of the socket related
1459 infrastructure is non-existent, practically speaking.) [45a9f36]
1461 - *quote-fold* has been temporarily disabled, as it is not multibyte
1464 No review for v14.4. And today is Friday, the 13th. Ouuuh!
1469 I should *maybe* should have and want to give prominence to
1470 Martin Neitzel for this, i maybe have misunderstood.
1472 - Bugfix *synchronous* *pipe-** execution..
1474 Well, unfortunately yet another newly introduced bug slept in
1475 S-nail v14.3[.1] -- [a8d724b3, Add @ and @& shell command prefixes
1476 for pipe-MIMETYPE, 2013-05-03] falsely changed the waiting state
1477 for subprocesses, as has shown up by a HTML-only mail on the
1479 'Seems i'm collecting one line fixes in this codebase; this needs
1480 to change in the future.
1485 I want to give prominence to Juergen Daubert (jue AT jue DOT li), who
1486 reported that i've broken plain-old unfancy send mode in 14.3.
1488 + Ok, i'll hope we're out of new errors for the v14.3 series with that.
1490 - New variable: *batch-exit-on-error*.
1491 Only works if the new -# command line option has been given, and will
1492 check the "current" exit status whenever one operation completes
1493 (S-nail returns to the command prompt).
1494 If the exit status implies error (e.g., sending the last message
1495 failed) then we exit forcefully with that error status. (The normal
1496 behaviour is that the status is reset when the command loop ticks.)
1499 - While here again, i've added the new -# command line option.
1500 This is the first step to implement a reliable batch mode;
1501 unfortunately it still selects the users system mailbox on startup,
1502 because we simply cannot go to "no" mailbox for quite some time -- at
1503 some future time we will be able to go to some VOID thing, and then
1504 this will end up as a rather efficient batch mode.
1505 For now it sets *dot*, *emptystart*, *noheader* and *sendwait*, and
1506 also implies the -~ command line option. [7549569]
1509 printf "m ${MBOX}\n~s subject1\nE-Mail Körper 1\n.\n" &&
1510 printf "m ${MBOX}\n~s subject2\nEmail body 2\n.\n" &&
1512 ) | MAILRC=/dev/null "${NAIL}" -n -#
1514 - Also, -N set *header* instead of *noheader*. [7b4a13f6]
1517 - Plain old unfancy invocations like
1520 $ echo bla|s-nail ./FILE1
1522 had been broken (by [522cb3ec]). [260e19d]
1528 Thanks to Gavin Troy (gavtroy AT gmail DOT com) who inspired the @ and
1529 @& pipe-command prefixes.
1534 - S-nail has been registered at Coverity Scan, and the third build
1535 (after topic branches *coverity-444* and *coverity-444.2*) produced no
1536 more errors. (<http://scan2.coverity.com/projects/444>.)
1537 (Then i used POP3 and IMAP and fixed some SIGSEGV. ;) Still didn't
1538 look at S/MIME, Maildir, caches etc... o()
1540 - S-nail v14.3 doesn't produce any spurious linker warnings on
1541 OpenBSD 5.3; all (correct!) use cases of strcpy() and strcat() have
1542 been replaced. [7bdf330, 2c8d7cb]
1544 - This is the first release with a (though very short) review -- i'm
1545 slowly getting comfortable with the code. (But i'm too stupid to
1546 perform reviews on patches, 'always did reviews on C++/Perl/xy
1547 classes. Aaah, how beautiful ... objects.)
1552 - It is now possible to "call" macros without using the `call' command
1553 by prefixing them with a tilde, as in
1562 - Added the *pop3-bulk-load* option.
1563 Yes, there are mailing lists etc. which use plain text email, and,
1564 there, headers are often more data than the body, so it doesn't make
1565 sense to download the headers twice (unfortunately POP3 doesn't
1566 support a BODY command; if only it would support a RETRDELE command..)
1569 And yep, from this changeset on i personally use S-nail even over the
1570 network, no longer my stale and incomplete S-Postman. And i can tell
1571 you, this damn thing is so silent, i always set *verbose* not to go
1572 grazy ... but .. i hate to say it .. the healing will take time.
1574 - POP3 will now try to use APOP authentication automatically; thus the
1575 *use-apop* stuff has been replaced by *pop3-no-apop* options (just in
1576 case there are POP3 servers which advertise they support APOP but in
1577 fact fail to do so; anyone?) [6c3c5575]
1579 - Some IMAP segmentation violations have been fixed:
1581 ? fi imaps://user1@localhost
1582 Password:Interrupt <- CNTRL-C
1583 ? set imap-auth=cram-md5 <- hey, 'forgot to set correct auth
1584 ? fi imaps://user1@localhost
1585 IMAP write error: error:140D00CF:SSL routines:SSL_write:protocol is shutdown
1588 And also, when *folder* was set to an IMAP account but hasn't been
1589 opened yet, and no IMAP account ever has been opened, a string
1590 comparison against a NULL pointer yet caused a SIGSEGV, too.
1593 - `set folder=' now tolerates `%:' and expands PROTOs stuff etc.:
1595 ? short xp %:imaps://user1@localhost
1598 Pure convenience so that it doesn't need to be typed twice (still no
1599 completion in sight...). Note that setting *folder* to a POP3 box
1600 will now be actively rejected. [b12b17f5]
1602 NOTE: while implementing this i've detected another dead-end
1603 miscondition in S-nail -- you really should ensure that your target
1604 folder/box is connected before you leave your current POP3/network
1605 based folder, if there is data to be moved to the target (i.e.,
1606 mbox). This problem will persist for a long time due to the way the
1607 entire codebase functions; i hope i can find a short/mid-term
1608 solution, but the real healing will take years. The mentioned
1609 solution would at least make S-nail interruptable, currently we get
1610 stuck and interrupts are blocked...
1612 - If you're using S-nail on Mac OS X and have seen some segmentation
1613 faults when expanding shell stuff then you may be pleased to hear that
1614 S-nail now works around an Apple bug. [63273772]
1616 - The builtin mime.types have been corrected and a lot of new ones have
1617 been added. New data from
1618 <http://svn.apache.org/viewvc/tika/trunk/tika-core/src/main/resources/\
1619 org/apache/tika/mime/tika-mimetypes.xml>, thanks! [8072fcb6]
1621 - BEWARE: handling of command line arguments has changed a bit!
1623 1. The -D, -d, -E, -i, -N and -v command line options are now
1624 implemented by means of setting the respective option, as via -S.
1625 (This means that from now on resource files can only *temporarily*
1626 overwrite command line arguments.)
1628 2. The -I and -T command line arguments have been dropped.
1629 It seems Gunnar Ritter stopped developing nail/Heirloom mailx once he
1630 started implementing Newsreader functionality. It'll take a long time
1631 until we get there, so for now drop all the Newsreader stuff.
1633 3. Handling of -r has been changed. E.g.:
1635 s-nail -A test -Snoeditalong -r 'La mort est <fem@me>' -d
1636 ? set from=bummer@m1.com
1640 Sendmail arguments: "sendmail" "-i" "-r" "fem@me" "t1"
1641 ? set from=bummer@m2.com
1644 Sendmail arguments: "sendmail" "-i" "-r" "fem@me" "t2"
1648 s-nail -A test -Snoeditalong -r '' -d
1649 ? set from=bummer@m1.com
1653 Sendmail arguments: "sendmail" "-i" "-r" "bummer@m1.com" "t1"
1654 ? set from=bummer@m2.com
1657 Sendmail arguments: "sendmail" "-i" "-r" "bummer@m2.com" "t2"
1659 [*main-fun-cleanup* topic branch]
1661 - *smime-sign-include-certs-** stuff works again, oops.. [9a8597c6]
1663 - A whole lot of smallest and small fixes due to registration at
1664 Coverity Scan, as project 444. Error handling in S-nail is ridiculous.
1665 [*coverity-444* and *coverity-444.2* topic branches. The sheer number
1666 of fixes was the reason to sit down and go for unplanned S-nail v14.3]
1668 - *idna-strict-checks* has been dropped. It's silly to have in a MUA,
1669 especially given that GNU LibIDN doesn't ship with a lot of rules.
1670 We were able to drop quite some code (and a use-after-free, too :().
1673 - The ~p tilde command displays attachments more verbose.
1674 Until the big big MIME and send layer rewrite :) this is intermediate
1675 since until then we do not really know neither MIME type nor charset
1676 of an attachment at the time this is displayed (for sure). Yet
1677 i think it's nicer to show what we have than keep it the way it was.
1680 - @ and @& shell command prefixes have been added for the pipe-MIMETYPE
1681 mechanism. The former suppresses filters if multiple messages are
1682 displayed at once, the latter adds asynchronous program execution on
1683 top of that. E.g., to display PDF documents, but only if you
1684 *explicitly* address the message *alone and by itself*, and without
1685 blocking S-nail and the $PAGER, do:
1687 set pipe-application/pdf="@&cat >"${TMPDIR}"/s-nail${$}.pdf;\
1688 mupdf "${TMPDIR}"/s-nail${$}.pdf; rm "${TMPDIR}"/s-nail${$}.pdf"
1690 (Inspired by Gavin Troy.) [a8d724b3]
1692 Note: most of that had been posted to nail-devel@ already, but it was
1693 tweaked ([251b636]) so that you now *really* have to say `p MSGNO' to
1696 - The NETLESS CONFIG= has been removed; it is almost identical to
1697 MINIMAL now (i.e., without WANT_JUNK and WANT_SCORE).
1699 - WANT_JUNK and WANT_SCORE have been disabled by default.
1700 They don't seem to be too useful; i hope i can implement
1701 a SpamAssassin hook for (downloaded) mail messages for v14.4.
1702 If so, expect these two "modules" to become removed completely.
1707 Another unplanned (minor) bugfix release after Gavin Troy (gavtroy AT
1708 gmail DOT com) pointed out that MIME CTE decoding was broken, who
1709 i therefore want to give a lot of prominence right here.
1711 - Fix MIME content decoding which has been broken by [01c0e135].
1718 An unplanned (minor) bugfix release after i've found two bugs today and
1719 heard from Jérémie Courrèges-Anglas (jca+nail AT wxcvbn DOT org) that
1720 there exists a S-nail OpenBSD package.
1722 I want to give prominence to the following people that helped to
1723 improve S-nail(1) during this development cycle, in order of
1724 appearance: Dirk Peters (peters AT schwertfisch DOT de).
1726 Thank you very much, and best from Germany!
1728 - Some warnings of newer clang(1) versions were silenced, including yet
1729 another alloca(3) problem (see *memtracer* topic branch in v14.0
1732 - Tweaking the MIME boundary detection left a little hole that could
1733 cause boundaries not to be detected, as has been shown by a Microsoft
1734 Word generated mail on the ICU list. [11e5fb5b]
1736 - A format string could overflow bounds if unrealistic
1737 (18446744073709551615) line numbers or message sizes would have been
1738 produced. [faa65c40]
1740 - An algorithmic error could cause overlong lines which wrapped around
1741 to the next display line. [ade52660]
1744 v14.2, 2013-03-15 [v14.1, 2013-03-12]
1745 -------------------------------------
1747 I want to give prominence to the following people that helped to
1748 improve S-nail(1) during this development cycle, in order of
1749 appearance: Martin Neitzel, Christos Zoulas, Stephen Isard, jgw@txo.org
1752 Thank you very much, and best from Germany!
1754 + v14.2 differs from v14.1 only by one commit, one that fixes
1755 (mime_fromhdr(): partial rewrite using n_iconv_str(), 2013-03-12),
1756 which i hastily implemented just hours before the release of v14.1,
1757 and simply shouldn't have made it (into there).
1758 The v14.1 tarball has been removed from the server.
1760 - A fix for the quoted-printable codec: "message truncation" occurred
1761 when a mail maliciously used a soft linebreak to escape the linebreak
1762 of a completely empty line.
1763 (That resulted in 0 written and 0 leftover bytes, a condition that was
1764 declared erroneous back in november 2012 when i started handling I/O
1767 - The "folders" command will work again when given an argument.
1768 A fault of mine introduced in (cmd1.c: expand() may fail, 2012-10-23).
1770 - The Base64 codec has been touched again, and we are finally capable to
1771 perform sequential decoding; this was targeted for the MIME/send layer
1772 rewrite, but it actually was possible today.
1773 The result as seen in ps(1), running on the Base64 encoded HTML5
1774 standard (4622545 bytes HTML, with a NUL appended to force Base64
1775 encoding, resulting in a 6244793 bytes email):
1777 7420 s006 S+ 2:22pm 0:10.65 plain-nail -f HTML5
1778 1440 s006 S+ 2:23pm 0:00.36 ./s-nail -f HTML5
1780 (So the only thing that is left for a good throughput is sequential
1781 decoding of quoted-printable encoded parts that maliciously use soft
1782 linebreaks to convert an entire part to a single line. And i've seen
1783 that from Apple Mail.)
1785 - New option: *mime-allow-text-controls* (rather long manual entry).
1787 - *smtp-auth-password-user@host* and *smtp-auth-user-user@host* will
1789 (Reported by jgw@txo.org in November 2011, fixed by Gavin Troy in
1792 - Most *headline* formats now do support the '-' left-alignment flag.
1793 Note that you most likely have to change your *headline* accordingly.
1794 (The still missing %n format is one reason why there will be v14.2.)
1796 - *datefield* and *datefield-markout-older* can now be set to
1797 strftime(3) format strings (except %n).
1798 (From Stephen Isard's wishlist.)
1800 - A possible SEGV has been found and also fixed by Stephen Isard.
1801 (The "legendary" cross-world stereo fix!)
1803 - Wow! S-nail will finally compile on GNU based Linux systems like
1804 Slackware 14 etc. (Found while hunting bug reported by
1807 - New option: *datefield-markout-older* can be used to choose
1808 a different date display for mails that are older than six months,
1809 in equal spirit to what POSIX describes for the -l option of the ls(1)
1810 command (Stephen Isard).
1812 - (Exotic) Years are (would) now (be) interpreted correctly according to
1815 - CRAM-MD5 usage has been fixed.
1817 - *folder* updates are now tracked when set, and we will show the
1818 realpath(3) name of it, showing PREFIX..SUFFIX if that wouldn't fit on
1820 Tracking updates made it also possible to perform other more expensive
1821 tasks when setting *folder*, so that it is now possible to do
1827 et cetera (both ideas by Christos Zoulas).
1829 - Bugfix for the ~@ tilde-escape in non-interactive mode.
1830 (readtty(): quick shot: work in pipelines (on non-TTY).., 2013-01-25)
1831 introduced the possibility to "read data from the terminal" (STDIN
1832 that is) in non-interactive mode.
1833 The manual documents that attachment input must be terminated with an
1834 empty line, but if that had been omitted, as in the example below, we
1835 would have yet entered an endless loop.
1837 $ cat <<_EOT | /s-nail -~ -s boom ./OUT
1843 - Alias expansion will now be performed for members of Reply-To: fields
1846 - Decoding quoted-printable will now be more relaxed.
1847 (Even though the standard says that users should be given a hint when
1848 input is not absolutely clean; a possible warning will be added later,
1849 when we have an error message ring.)
1851 - New option: *mimetypes-load-control* can be used to control which of
1852 the mime.types resources will be loaded.
1854 - The builtin default mime.types have been extended a bit.
1859 I want to give prominence to the following people that helped to
1860 improve S-nail(1) during this development cycle, in order of
1861 appearance: John Dodson, Gianluca Ramunno, and Anon Ymous from the
1867 - Encoding defaults to *quoted-printable* not *8bit*.
1868 This has no technical background except that i think it's the better
1871 - Small progress for the "getting stuck due to the current folder
1872 becomes inaccessible due to whatever reasons" problem.
1873 (schdir(): realpath() local files before leaving CWD.., 2013-01-08)
1875 - The names of temporary files have changed. Whereas not all uses of
1876 temporary files already use really meaningful names, it has yet become
1877 possible to use the pattern "*mail-*"; or, to be compatible with
1878 NetBSD Mail(1) in one go, "*mail*". (E.g., in my ~/.vimrc you'd read:
1879 :au BufRead,BufNewFile *mutt*,*mail* setl fenc= | setf mail
1880 [the *mutt* is a leftover from times when i've used MUAs that suck].)
1885 - The Quoted-Printable MIME handling has been rewritten completely.
1886 We now correctly encode files with the MS-DOS newline sequence (CRLF).
1887 (Part of the *mime-cte* topic branch.)
1889 S-nail(1) continues to be able to handle text messages and text
1890 attachments without a trailing newline, but because these
1891 Content-Transfer-Encoding related things are now handled by the C-T-E
1892 layer instead of by sendout.c a text message body that comes in as
1893 part of a complete message via the -t command line option will loose
1894 the missing final newline (i.e., it'll gain one).
1895 This problem does *not* occur when *only* the message body comes in
1896 via STDIN, as in 'cat FILE | s-nail', but *only* when the -t option is
1898 (sendout.c: does no(t/ longer) know about CTE internals!, 2013-02-09)
1900 - Filename arguments for -a are now processed *after* all the resource
1901 files have been loaded etc., so that the usual "folder" specifics can
1902 be used (provided that proper care for shell quoting was taken).
1903 ((main(): delay -a processing.., 2013-01-10), as a part of the
1904 *mainaflags* topic branch.)
1906 - (d38c5bd, When the write command asks.., 2004-11-23) added support
1907 for pipes when saving attachments during a "write" command.
1908 It however used the wrong SIGPIPE signal handler; e.g.:
1910 Enter filename for part 2 (application/x-gzip): |exit
1913 Of course, it still performs a jump and that most likely leaves memory
1914 chunks behind, thus causing some memory leaks. This will be
1915 a long-term problem (you may want to read [mime.c:fwrite_td(): TODO
1916 notes on unfixable leaks, 2013-01-14] for more).
1917 (send.c:sendpart(): fix longjmp() SIGSEGV.., 2013-01-29)
1919 - Fixed a name quoting regression that i've introduced in
1920 (Rewrite *extract().., 2012-10-20), that would have caused
1921 "x \"y\" z" to become "x"y" z" instead of "x "y" z".
1922 (S-nail still does not really have RFC compliant parsers, just as
1923 NetBSD Mail(1) has, i.e., there are structured and unstructured fields
1924 etc... I hope i can provide them in v15.0.)
1925 (names.c:yankname(): fix quote regression.., 2013-01-29)
1927 - The IDNA conversion now assumes domain names are specified in
1928 *ttycharset*, rather than in the LC_CTYPE locale charset.
1929 I.e., it integrates into the usual character set specifications.
1930 (IDNA: honour *ttycharset* for domain names, 2013-01-18)
1932 - The new *editalong* variable will automatically spawn an editor when
1933 composing a mail in interactive mode, just as if `~e' was given.
1934 (Add new *editalong* variable, 2012-01-07)
1936 - The manual has been converted to mdoc.
1937 (The manual has been converted to mdoc, 2012-12-28)
1939 - The ~@ tilde escape, when given filename arguments, will treat the
1940 arguments as a comma-separated instead of a whitespace-separated list.
1941 (collect: change separator of ~@ tilde escape.., 2012-12-28)
1943 The interactive mode of ~@ has also been changed, rather massively.
1944 Please do reread what the manual says.
1945 ((collect: support multiple attachment charsets.., 2013-01-23), as
1946 part of the *attach* topic branch.)
1948 - Thanks to Gianluca Ramunno (ramunno DOT gianluca AT gmail DOT com)
1949 S-Nail will no longer try to issue a STARTTLS command when it is about
1950 to establish a SMTPS connection, a task that logically fails since the
1951 connection is already secured.
1952 (Interestingly the nail codebase performs the necessary test for IMAP
1954 While here the undocumented nail v11.0 *smtp-use-tls* legacy option
1956 (Fix SMPTS with a set *smtp-use-starttls*.., 2012-12-22)
1958 - The RFC 4155 compliant MBOX quoting is now exclusively used, the
1959 shitty *posix-mbox* variable has been removed again.
1960 (Shitty because i've implemented RFC 4155 compliant MBOX quoting and
1961 tested it, then added *posix-mbox* for those who liked the old
1962 behaviour and did not re-test -- the final code path was buggy.)
1964 In mails newly created and saved by S-nail(1) no From_ quoting at all
1965 will be used no more, but instead the rewritten MIME file classifier
1966 will detect unquoted From_ lines and enforce quoted-printable encoding.
1967 (This is an approach that is S/MIME compatible all through the way as
1968 the file data is not modified at all, but only encoded, so that the
1969 data checksum is not changed.)
1971 In yet existent mails that S-nail copies or moves around without
1972 reclassification an RFC 4155 compliant From_ line detector will apply
1973 MBOXO quoting (prepend a single '>') as necessary.
1974 Different to the old MBOXRD behaviour S-nail will neither quote yet
1975 quoted From_ lines ('>>From xy' -> '>>>From xy') nor will it unquote
1976 one quote level when reading etc. mails ('>> From xy' -> '>From xy').
1977 As a result the code could be simplified.
1979 This changeset also incorporates a fix for NetBSD PR bin/47453, as
1980 reported by Martin Brandenburg. I.e., some mailers, noticeably
1981 UW-imap (with MBX format only?), use non-compliant From_ lines with
1982 RFC 822 date specifications. Be aware of 'em.
1983 (RFC 4155 MBOX, and drop *posix-mbox* and foldergets().., 2013-01-06)
1985 - *rfc822-show-all* has been removed.
1986 It didn't work properly for more complex MIME structures, like
1987 message/rfc822 messages with attachments etc., just as i've seen today
1988 on the file(1) mailing list.
1989 So, instead of hacking it now i've dropped it and will come back with
1990 a better solution when the MIME and send layers have been overhauled.
1991 I.e., the real intent was to be able to specify that an embedded
1992 message/rfc822 is treated as a *unity*, and that's the goal.
1993 (Drop *rfc822-show-all*, 2013-01-23)
1994 [The manual will be adjusted in a different commit.]
1996 - *rfc822-no-body-from_* has been renamed to *rfc822-body-from_*.
1997 It thus must be set explicitly.
1998 On the other hand it now catches all cases...
1999 (*rfc822-no-body-from_* -> *rfc822-body-from_*, 2013-01-23)
2000 [The manual will be adjusted in a different commit.]
2002 - The new *charset-7bit* (defaults to US-ASCII) and *charset-8bit*
2003 (defaults to UTF-8) have been introduced.
2004 These are used if seven bit clean data is to be sent, and no
2005 *sendcharsets* are set or the convertion of all of them failed,
2008 - There is no functional change unless there is iconv(3) support.
2009 - There is no functional change unless you set them.
2010 (Introduce *charset-8bit* and *charset-7bit* variables.., 2013-01-18)
2011 [The manual will be adjusted in a different commit.]
2013 In addition the new *sendcharsets-else-ttycharset* variable can now
2014 be used to automatically use *ttycharset* as a *sendcharset(s)*,
2015 regardless of the new *charset-8bit* variable.
2016 (Add *sendcharsets-else-ttycharset* variable, 2013-01-24)
2017 [The manual will be adjusted in a different commit.]
2019 NOTE: before we apply charset conversion we now perform a string
2020 comparison to see wether character sets are identical. If the strings
2021 match (case-insensitively), then *no* conversion is performed.
2022 This means that code like
2024 $ printf "LATIN1: \0376" | s-nail -Ssendcharsets= -s boom ./out.txt
2026 *succeeds* in an UTF-8 environment now, whereas older versions would
2027 fail with an "illegal byte sequence" error (unless the iconv(3)
2028 library of the system would not perform any conversion that seems
2029 superflous, of course).
2031 I thought about making this optional, but, in fact, if this would be
2032 done in an environment without iconv(3) support then the result would
2033 be equally corrupt. And the way it is now we save the expensive and
2034 superflous conversions. (See TODO for more.)
2036 Please *do* reread the manual section "Character sets".
2037 +++++++++++++++++++++++++++++++++++++++++++++++++++++++
2039 - An attempt was made to improve MIME Content-XY: detection.
2040 It should be more RFC compliant, and just overall better :);
2041 a simple one-pass classifier cannot match libmagic(3), of course.
2043 This changeset removes support of the long obsoleted (4fee1ef,
2044 2005-01-06) *charset* variable, as well as for the
2045 *maximum-unencoded-line-length* variable that has been introduced in
2046 (48a652bd, 2005-07-26).
2048 For S-nail v14.0 it'll be no longer necessary to do
2050 $ tr -d '\015' < input | s-nail ...
2052 to transport files which use the $-DOS (terminal) newline (sequence).
2053 We still depend upon *sendcharsets* for a while, though.
2054 (Rewrite file-content classification.., 2013-01-02)
2056 - The new *mime-counter-evidence* variable can be used to force
2057 a classification of non-text MIME parts (attachments) by their
2058 filename, i.e., a "reverse-classification" just as would be performed
2059 if S-nail(1) would itself *send* the file(name). This can help
2060 against some stupid MUAs (Apple Mail?) that send .diff etc. files as
2061 `application/octet-stream' parts etc.
2063 At a later time this may become a valued option, causing a temporary
2064 save of unnamed attachments followed by a MIME classification of the
2065 file contents, followed by forced treatment as plain text if it seems
2066 to be human readable. But not yet. Just to warn you.
2067 (Add *mime-counter-evidence* variable.., 2012-12-29)
2069 - The special "pipe-" command "@" can be used to force treatment of
2070 a MIME message part as plain text (e.g.,
2071 'set pipe-application/pgp-signature=@' will henceforth print those
2072 signatures inline and as plain text).
2073 (Introduce the special "@" "pipe-" command, 2012-12-27)
2075 - The MIME types (as from mime.types(5)) will now be cached. Before
2076 all possible sources would have been opened, read and parsed for each
2077 and every message part that required detection of the MIME
2079 The new "mimetypes" command can be used to show or clear that cache.
2080 (Add mime.types(5) cache.., 2012-12-27)
2082 - A small set of MIME types (template: ./mime.types) will now become
2083 compiled into S-nail(1), and be used as a fallback if there are no
2084 ~/.mime.types and/or no /etc/mime.types, or those didn't contain
2085 a matching type. E.g., NetBSD 6 doesn't ship a default database.
2086 Also, file extensions will be matched case-insensitively (case of
2087 attribute values is not specified afaik?).
2088 (Introduce compiled-in mime.types(5).., 2012-12-21)
2090 - The undocumented *charset7* variable was removed.
2092 - The "Message X:" display leader has been changed and will henceforth
2093 be matchable via "^[-- Message \d+ -- \d+ lines, \d+ bytes --]:$".
2094 These lines can no longer be suppressed by setting the *quiet*
2095 option (which was yet possible for print and top, though undocumented).
2096 (Change "Message X:" display message.., 2012-12-20)
2098 - When displaying multipart messages the "Part X:" introductional string
2099 has been changed; if the Content-type: header is not *retain*ed, then
2100 this string will include the part's type and size. Ditto for
2101 Content-disposition: and a mentioned attachment filename.
2102 This is a first step only, for the final version the MIME and send
2103 layers will have to be adjusted. But the string will be matchable via
2104 a "^[-- #.* --]$" regular expression from now on.
2105 (Change "Part X:" display message.., 2012-12-20)
2107 - MIME boundaries in multipart messages are now handled better in that
2108 no boundary string should get through to the display.
2109 (Tweak MIME boundary detection.., 2012-12-20)
2111 - A couple of long standing, even pre-Heirloom mailx(1) memory leaks and
2112 segmentation violations, most of them related to configurations
2113 without alloca(3) support, as well as one leak that i have introduced
2114 when i implemented RFC 4155 MBOX handling, have been fixed.
2115 But S-nail should now survive non-alloca(3) configurations.
2116 (*memtracer* topic branch.)
2118 - The Base64 MIME handling has been rewritten completely.
2119 This was an urgent topic, because the old implementation (a) read in
2120 all lines of a base64 encoded text part, repeatedly resizing a string
2121 storage and repeatedly decoding that string until all the lines have
2122 been swallowed (i.e., or by accident the last decoded byte was
2123 a newline character, and that in turn may of course have fucked up for
2124 multi-octet encodings, dependent on the actual byte-order), (b) used
2125 function local static data to keep state in between multiple
2126 invocations, which messed up multi-byte/-octet encodings like this
2128 �5��ɽ���Aɥ����́��٥��������[lots of data follows]
2130 and (c) did not perform any error checking at all.
2131 The new one does not run into the problem that (a) tried to circumvent
2132 since leftover decoded data (as opposed to leftover *encoded* data) is
2133 transported along the call-chain for later use. It adds a minimal set
2134 of error handling ('may now see "[Invalid Base64 encoding ignored]"),
2135 with more to become possible in later S-nail versions when the entire
2136 layers are reworked. (Until then DOS newline sequences [CRLF]
2137 embedded into base64 will no longer be decoded to Unix LF newlines.)
2138 Base64 encoded lines will now be 76 characters long, as stated (as
2139 a maximum value) in RFC 2045, not 72 as before.
2141 The Base64 code core has been shamelessly stolen from NetBSD's
2142 Mail(1), and i guess it was the second time that this happened :=).
2143 (*base64-rewrite* topic branch; and reworked later on the *mime-cte*
2146 - The string allocation strategy has been tweaked some more to, i think,
2147 a final version (regarding algorithm).
2148 In normal non-interactive send mode it should now no longer need any
2149 dynamic memory at all (unless some dozen recipients are specified).
2150 (Several other places still use normal dynamic memory, of course.)
2151 (*dope-stringdope-again* topic branch.)
2153 - Support for NSS (Network Security Services) has been removed.
2154 I've never worked with it and are, regarding the complexity of
2155 network security, not willing to spend any time on it.
2156 SSL is installed on all systems i'm using and/or testing on by
2157 default, and so i've choosen to go this way.
2158 (It may be that sometime in the future S-nail will add support for
2159 libcurl(3) connectivity, and then it may happen that not only NSS
2160 support is reintroduced again, but also GNU TLS. All of that applies
2161 to network connectivity only, however, not to S/MIME afaik.)
2162 (*drop-nss-support* topic branch.)
2164 - I finally got a glue and understood that Sourceforge does (a) not
2165 support symbolic links and (b) doesn't like dots as regular parts of
2166 filenames. This means that all this time the promised s-nail.tar.gz
2167 symbolic link did not work, and that s-nailv13.3.tar.gz wasn't
2168 accessible either (via the web interface).
2169 In the future S-nail(1) will not provide any more symbolic links (the
2170 Sourceforge website offers a "download latest" thing which seems to
2171 work), and use underscores in filenames -- s-nailv13.3.tar.gz has been
2172 renamed to s-nailv13_3.tar.gz. The tags continue to use dot notation.
2175 - The *heirloom-plus* support branch has been removed.
2176 The code bases diverged a lot and even more to come.
2177 It doesn't make sense to put any effort in that.
2182 - Configuration on UnixWare 7.1.4 will succeed (shell issue fixed).
2184 - Even on DragonFly BSD the IMAP GSSAPI is now found
2185 (in /usr/pkg/include/krb5/gssapi/gssapi.h).
2187 - Support for pkgsrc(7) systems and automatic integration of
2188 C_INCLUDE_PATH and LD_LIBRARY_PATH path configurations.
2191 - Fixes a mortally embarassing regression that the current maintainer
2192 introduced before i really knew what i was doing, in (If *record* is
2193 set, avoid writing dead content twice.., 2012-09-14).
2194 It hit users that send through a MTA and have *record* set; in this
2195 combination data would not have reached the MTA.
2196 Interested parties may read the comment in savedeadletter() (part of
2197 the changeset) or the (Fix MTA/*record* descriptor clash..,
2198 2012-11-10) commit log.
2200 Deepest apologies to tortured users from the current maintainer!
2202 - RFC 4155 compatible MBOX file handling has been introduced, and so
2203 S-nail is now on par with (at least) NetBSD Mail in respect to this.
2204 It can be turned off with the new *posix-mbox* variable, which you may
2205 need to use since not all MUAs are capable to dig those MBOX files.
2206 E.g., less cutting-edge (.-) MUAs fail for this:

2223 I'm not completely happy since S-nail *does* still quote those lines,
2224 how rare they may be -- it *does* modify message content. mutt(1)
2225 implements something more clever and that is quoted-printable encoding
2226 of the "F" from "From", when seen at the beginning of a line.
2227 This, when applied to just *any* "^From", will be a non-modifying and
2228 all-compatible solution.
2230 - SEND_MBOX handling has been changed to discard any Content-Length: and
2231 Lines: headers when it rewrites a message by default.
2232 I know that mutt(1) generates them (why, after
2233 http://www.jwz.org/doc/content-length.html?).
2234 Anyway, S-nail does neither use nor manage them, so that any
2235 modification renders those fields invalid, and then it seems best to
2236 discard them anyway.
2237 You may turn the new behaviour off with *keep-content-length*.
2242 The problem was that i really wanted to release on a 25th.
2243 But i have been able to improve S-nail(1) some more, so that this is
2244 possibly the first real release of it. So i'll add only things that
2245 have changed since v13 -- please see below for the complete picture.
2247 - A new CONFIG=CUSTOM make directive was added, and the new user.conf
2248 variables WANT_SCORE and WANT_DOCSTRINGS have been added. It is
2249 possible to create a floating-point free S-nail(1) now.
2252 - If a feature is disabled not even functions stubs should remain now.
2254 - Many places which will work only with local filenames do now actually
2255 check that the target is a local filename.
2257 - Space-separated lists should work again, at a few places at least.
2259 - Tilde commands will be possible, even with -r.
2261 - The *sendmail-progname* has been added after NetBSD 6 dropped the
2262 send-mail entry in mailer.conf(5), which broke S-nail(1). Now users
2265 - When editing messages via ~e or ~v file and pipe addressees will no
2268 - If recipients occur multiple times spread over lists, i.e., To:, Cc:,
2269 Bcc:, then only one occurrence remains, and in the "highest-order"
2272 - The "list" command prints the list alphabetically sorted (somewhat).
2274 - The "help" and "?" commands take an optional argument that shows
2275 a synopsis string for the given command (unless WANT_DOCSTRINGS was
2278 - String allocations are now more efficient. The situation can still be
2279 improved. However, for the first time Berkeley Mail(1) integrates
2280 harmonically into the system allocator, which may madvise(2) unused
2281 memory to the operating system as necessary and/or possible!
2286 Well, a version number 13 is anyway an ugly thing...
2288 commit 4f534bb33b7c911272cc66a0e3a9e47b73ad8deb
2289 Date: 2012-10-25 20:46:07 +0200
2291 FIX MIME quoted-printable encoding (char cast)..
2296 Well, one of the things that have already been started in v13 is
2297 the turn from using "int" when working with 8-bit characters to
2298 "unsigned char" (and as long as we do not support wide
2301 Unfortunately one very important piece of code, that is handling
2302 encoding to quoted-printable, still used integer instead of
2303 unsigned char, which caused an automatic extension cast to take
2304 place, and that resulted in a messed up output.
2310 I want to give prominence to the following people that helped to improve
2311 S-nail(1) during this development cycle, in order of appearance: Martin
2312 Neitzel, Ezequiel Garzón, Björn Persson, Paul Vojta, and, especially,
2313 John Dodson for warm words from beautiful Australia! Many thanks also
2316 After i've officially forked nail(1) aka Heirloom mailx(1) as S-nail(1)
2317 on 2012-09-18 i have been able to work five weeks almost fulltime on
2318 S-nail(1) development. The first three weeks can be characterized as
2319 hectic fireworks here and there, but then it got better and i was able
2320 to work more or less topic-centric. In the meanwhile S-nail(1) is more
2321 than 230 commits away from the Heirloom base--and drifting further apart.
2323 S-nail(1) v13 is the first release of S-nail(1), but it was forked from
2324 Heirloom mailx(1) 12.5 7/5/10 that arose from Berkeley Mail 8. unless
2325 i'm mistaken. What characterizes S-nail(1) v13?
2327 - The build system has been reworked almost completely.
2328 It is possible to fine-tune which features should be present in the
2329 binary and which don't. The name of the binary can be chosen, and
2330 that choice is reflected all through the manual and the template
2331 resource file. The manual is always complete and thus may document
2332 features that are not supported by the actual binary, though.
2333 Please see INSTALL for more.
2335 - Compiler warnings can now be used. Please see the example WARN= flags
2336 in the Makefile, but '-Wall -Wextra -pedantic' should be silent though
2337 certainly insufficient to reflect the complex work of modern compilers.
2339 - The following recipient address list combines some of the major
2340 improvements that have been made:
2342 <addr1@cdröm.de> (bier) , ./file1,
2343 Steffen Smöregäs (Humbabä) <sauer@bäüer.de> (Hummpäa) ,
2344 sabberlot@träbbel.de , (bier2) <a2@bür2.de> ,
2345 a3@b3.de (bier3) , <a4@b4.de> (bier4, und \"bier5\") ,
2346 |cat > pipe1 , (bier 6) <a6@bür6.de> , ./file2 ,
2347 (co\$mm1) abc1@düf.de (cö,bmm,2) (co\"m\"m.3) ,
2348 co\$bmm1 \"c,ömm2\" co\"m\"m.3 <abc2@däf2.de> , |cat > pipe2 ,
2351 That, on a single line, may be given to ":m" or (quoted) on the
2352 command line, or to "~c" or whatever, and it will work as expected
2353 (well, everything else would be a bug..) and result in the following
2354 sendmail(1) invocation:
2357 <-i a2@xn--br2-hoa.de a3@b3.de a4@b4.de a6@xn--br6-hoa.de abc1@xn--df-xka.de abc2@xn--df2-qla.de addr1@xn--cdrm-7qa.de moppel@xn--hppel-jua.org sabberlot@xn--trbbel-cua.de sauer@xn--ber-qla4j.de>

2377 So list parsing has been fixed, IDNA support has been added, and it is
2378 possible to mix pipe and file recipients *and* multiple thereof, and
2379 the result is still correct for *all* of them.
2380 I think this kind of list can be given wherever a user can directly
2381 enter such a list. And i think all that is unique to S-nail(1).
2383 - When writing back edited messages the target MBOX mailbox can no
2384 longer become "corrupted" when the trailing newline was removed during
2385 the edit. Also affected FreeBSD and NetBSD mail(1).
2387 - A security fix for CVE-2011-2895 was applied.
2389 - The generated Message-Id: is now more human-friendly.
2391 - The -h command line option has been dropped. Use "-O -h XY" if your
2392 MTA really supports that.
2394 - The -O and -r command line options no longer enforce a one-shot send
2395 mode, and instead persist for the duration of the entire session.
2397 - Variables set via the -S command line option are now (un)set twice;
2398 immediately and after all the resource files have been loaded.
2400 - Other new or changed options/commands, in order of appearance:
2401 recipients-in-cc, smime-sign-include-certs, quote-fold, stealthmua,
2402 add-file-recipients, write, rfc822-no-body-from_, rfc822-show-all,
2403 mail/Mail, idna-disable, idna-strict-checks, ??
2405 - In the codebase itself an effort to reduce duplicate work and
2406 introduce caching, and to minimize the use of local variables, was
2407 started, but that is long term. A lot of improvements here and there,
2408 too, like using the well MD5 optimization from Wei Dai, Chris Torek's
2409 hash algorithm for hash tables etc.
2411 - Incredibly important: an heraldic animal was found: snailmail.jpg!
2413 The full history can be inspected by issuing the git(1) command
2415 $ git log --reverse s-nail..s-nailv13
2417 A new TODO has been introduced, and it is getting longer and longer.
