21 Thank you: Gavin Troy, Bob Tennent (rdt AT cs DOT queensu DOT ca),
27 v14.7.2 brings incompatible credential lookup changes when *v15-compat*
28 is set; the lookup order now is:
30 - *user-HOST*, *user*, [.netrc] ...
32 - *password-USER@HOST*, *password-HOST*, *password*, [.netrc] ..
34 Changelog in reverse order, oldest first.
36 ChangeLog (packager-affine)
37 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
39 - New configuration option WANT_AGENT to support *agent-shell-lookup*
40 (, -HOST, -USER@HOST) lookups of potentially encrypted password
41 storage (inspired by Gavin Troy) [b2d41d3,516a7f0]
43 - MAILSPOOL is now automatically set to /var/spool/mail if that
44 directory exists, only otherwise we use /var/mail [4a83018]
46 - WANT_GSSAPI is again enabled by default - Tarqi Kazan has correctly
47 pointed out that the system environment at compilation time is likely
48 to reflect the politics and/or preferred configuration of packagers,
49 and self-compilers have always the chance to configure themselves
50 (Tarqi Kazan) [398eb29]
55 - `un{,save,fwd}{ignore,retain}': let '*' mean 'all fields' [a1f1da9]
57 - Bugfix: `setenv' takes 1-1000 arguments, not exactly 2 [daf2ea8]
59 - New command: `varedit' edits the value of an existing variable in
62 - New commands: `File' (and `Folder') explicitly open a mailbox in
63 readonly mode, thus finally offering the possibility to avoid flag
64 updates etc. whenever so desired [b1f5f2d]
66 - Bugfix: since May the header display would display tabulators in an
67 UTF-8 environment as replacement characters [870b314]
69 - *mime-counter-evidence* now is a valued option. Set bit two (value
70 two) and the detected real MIME type is carried along with the MIME
71 part so that it is used instead of `application/octet-stream' to
72 lookup possibly registered *pipe-CONTENT/SUBCONTENT* handlers.
73 (Bob Tennent) [81473f8]
75 Also pipe handlers will now be passed several MIME informations via
76 environment variables, please see the manual for more.
77 (inspired by Bob Tennent)
79 - Resource file loading now prints a diagnostic when loading was stopped
80 due to a processing error. This behaviour is also required by POSIX.
81 (Bob Tennent) [fd42684]
83 - Incompatible changes in credential handling, as above.
86 - *netrc-lookup* is now a real chain and has -HOST and -USER@HOST
87 variants (though the latter only for password lookups) [59fc226]
89 - .netrc machine names are now lowercased before use [28c6fee]
91 - The manual has seen some reorderings, a TOC will be shown if you
92 '-dWANT_TOC=1' when using *roff(1) (as has been done for the online
95 - There is a new file `THANKS' [6b5cb3e]
97 ChangeLog (purely technical)
98 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
100 - IMAP and IMAP cache now use string relaxation which *drastically*
101 reduces memory usage on large mailboxes [e5598ce]
103 - Fixed compilation on old OpenBSD installations without wordexp(3) as
104 well as with GSS-API and WANT_AMALGAMATION and now using #pragma's to
105 get rid of some warnings [topic/ccstuff]
110 Thanks to Georg Schlisio (g DOT schlisio AT dukun DOT de),
111 Wiesław Magusiak (wiemag AT poczta DOT onet DOT pl), Tarqi Kazan and
114 Very special thanks: Gavin ".. .. Speeding kills. .." Troy from Ireland
115 and Ypnose "Gloria?? C'est une mouton!" from France.
117 Changelog in reverse order, oldest first.
119 ChangeLog (packager-affine)
120 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
122 - WANT_NOGETOPT is gone. [73f0605]
124 - WANT_NETRC: new option (on by default; see below). [topic/netrc]
129 - Manual slightly improved in respect to LC_ALL etc. settings.
130 The knowledge treshold value is much too high for a normal user;
131 i hope that at some later time we can offer much more (at least
132 optional) automation on the protocol level (e.g., timeout values,
133 protocol features supported by servers etc.), at which time we will be
134 able to make the manual more user friendly. (Georg Schlisio)
135 [56fab16,bd1e11f; ArchLinux Wiki]
137 - The `@' search command has new "header" keyword, which searches in all
138 headers. Shortcuts: "<" = "header", ">" = "body", "=" = "text".
139 ("body" and "text" still perform full text searches _including_ MIME
140 part header content.)
143 - The -O command line option is legacy and will vanish in v15.0.
144 Arguments to the MTA can henceforth be passed after a `--' separator
145 on the command line, as in
146 echo bla|s-nail -vvd -s sub some@where -- MTA ARGS MADE EASIER
149 - New *sendmail-arguments* option; content will be (converted to list
150 and) joined onto other MTA command line arguments (Wiesław Magusiak)
153 - *colour-pagers* is gone -- instead we have *colour-pager*, which is
154 a boolean and off by default. We again set LESS (and LV) environment
155 variable(s) to automatic turn on colour support in $PAGERs, but only
156 if the variable in question is not yet set. (That is -- in order to
157 get coloured $PAGER you at least have to set *colour-pager* now.)
158 (Tarqi Kazan) [b794f5e]
160 - Terminals no longer need to be added to *colour-terms* if their name
161 (in $TERM) includes the string "color". (Gavin Troy) [ce2c7f6]
163 - Karol Blazewicz opened a discussion in the ArchLinux Forum (s-nail
164 14.7-1 doesn't work [1]) but i didn't realize his actual problem --
165 luckily Gavin Troy wrapped his head around the real problem, and that
166 finally opened my eyes against a whole can of worms in the new URL
167 and credential handling!
169 Then Ypnose also came along and reported an issue with IMAP handling
170 that was related to the compatibility credential handling of the new
171 URL and credential layer.
173 (Gavin Troy, Ypnose, Karol Blazewicz) [a5c40ba]
174 [1] <https://bbs.archlinux.org/viewtopic.php?id=182653>
176 - We now also have -HOST and -USER@HOST *smtp-use-starttls*. [bfb186a]
178 - Gabby history entries will now be saved and restored as such, in case
179 *history-gabby-persists* is set. (For this to work properly
180 a possibly existing history file needs to be reset.) [b5502cc]
182 - We now have optional .netrc support (*v15-compat* set).
183 Set *netrc-lookup* and we'll look in $NETRC / ~/.netrc for user
184 credentials. The `netrc' command will show or clear the entry cache.
185 E.g., this is my new account macro:
187 set v15-compat ssl-method=auto
189 set smtp=smtps://smtp.yandex.ru:466 smtp-auth=plain smtp-hostname= \
191 ghost xp 'fi %:pop3s://pop.yandex.ru'
192 ghost xi 'fi %:imaps://imap.yandex.ru'
194 As an extension to the .netrc syntax we support a single
195 introductional subdomain wildcard, e.g., my relevant ~/.netrc entry:
197 machine *.yandex.ru login NAME password PASS
199 Following a suggestion of Gavin Troy we have multi account support,
200 i'm not quite sure wether this is portable across .netrc using
201 applications, e.g., i could have written the above like
203 machine *.yandex.ru login NAME
204 machine *.yandex.ru password PASS
205 machine *.yandex.ru login NAME2
207 (I hope i don't lie and this really works.)
208 (Suggested by Gavin Troy and Ypnose, testing and feedback Gavin Troy)
211 - Add primitive support for RFC 3798 via the new
212 *disposition-notification-send* variable. This is not yet
213 a truly conforming implementation (it simply injects the necessary
214 header) and it requires the *from* variable to be set.
215 More in the far future, sorry. (Wiesław Magusiak) [ca31d32]
217 ChangeLog (purely technical)
218 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
220 - Interrupt protection during (recursive) macro calls with `localopts'
221 on should now no longer be crashable at all. Quote [a4e85c0]
222 It is of course all pretty intermediate until we have a signal
223 manager and we can actually poll signal states at those places where
224 we are capable of and desire to handle them. But it should work
225 today and look nicer than it did.
226 [25caeb9,592499f,a4e85c0]
228 - `ghost' handling performs more strict name checking on ghost names in
229 order not to allow names which would later not be parsed as a whole.
232 - Dropped catopen(3) support (we never really had it)! We will have
233 a new S-nail-specific gettext(3)-alike thing in v14.8.
234 [topic/i-wanna-have-a-dog]
239 Thanks go to Tarqi Kazan (tarqi AT cfs DOT or DOT gs) and Johannes
240 Löthberg (johannes AT kyriasis DOT com), as well as Martin Neitzel.
241 (And the winner is... Gavin Troy for his role in "Silence from Ireland".
247 - Since S-nail now performs more-or-less proper percent-encoding as per
248 RFC 3986 users of *imap-cache* have to (either throw away and recreate
249 or) adjust their local cache, e.g. as follows (adjust CACHEDIR and
250 echo(1) to mv(1) as necessary; won't work with paths with whitespace):
252 $ CACHEDIR=${HOME}/traffic/.mail-cache; \
253 find ${CACHEDIR}/ -depth -type d |
256 r=`echo ${b} | sed -e s/:/%3A/g -e s/@/%40/g`
257 if [ ${b} != ${r} ]; then
259 echo ${d}/${b} ${d}/${r}
266 - New variable *history-gabby* can be set to add much, much entries into
267 the history than is done normally.
268 For the NCL only, setting *history-gabby-persist* will cause those
269 entries to be saved into *NAIL_HISTFILE*, too, which they are not by
270 default with it (the other command line editors should always save).
273 - The `online' alias for `connect' has been obsoleted. [d5cfde4]
275 - New CONFIG=MAXIMAL make option. [c0d4087]
277 - Support compilation on new OpenBSD with their reduced OpenSSL clone.
278 This topic also includes the real solution for getting rid of
279 a strcat(3) warning that i reintroduced with s-nail-14_5_2-smime.patch.
282 - Our -r command line option is now mapped to a `-f' MTA option -- the
283 sendmail(1)-compatible `-r' is long obsoleted! (Johannes Löthberg)
286 - New `elif' command so that we now have if..elif..else..endif.
287 If the optional regular expression support is available the new
288 conditions `=~' and `!~' can be used to perform (case-insensitive)
289 regex matching with `if' and `elif'. [topic/condsplus]
291 - New `~R' tilde escape (like `~r', but indent lines). [fae1f29]
293 - Improved multibyte-safety (e.g. for *prompt*) and a bit of
294 compatibility ("support" would be a wording much too strong) for
295 bidirectional text via the new *headline-bidi* variable.
296 [topic/unibidi, topic/mbbidi]
298 - Diversified behaviour of -v command line option as well as *verbose*
299 to support multiple levels of verbosity; the latter is now ternary
300 when set and boolean when unset.
301 This was the ground on which SSL certificate validition verbosity was
302 implemented (*verbose* level 1: certificates, level 2: network
303 communication et cetera), though much is left to do.
304 This has been suggested long ago by (Martin Neitzel). [topic/smverb]
306 - ^C in compose mode with *ignore* set acts now POSIX compatible
309 - If *encoding* is set to base64 then we don't ignore that user
310 wish and use quoted-printable (when 7bit doesn't suffice) [2ca201f]
312 - New `urldec' and `urlenc' commands. [63e869e, fbd95e8, 0af5b1b]
314 - New `setenv' and `unsetenv' commands. [5e2ed79]
316 - Support for GSS-API authentification has been added (request and
317 testing by Tarqi Kazan).
319 Note that the following implicit relation is gone:
321 If set to `login', or if unset and smtp-auth-user is set, `AUTH
324 This topic branch also added support for the SUBMISSION protocol of
325 RFC 6409, so re-reading the *smtp* manual may bring benefits.
328 - A new, backward-incompatible URL syntax and credential lookup scheme
329 has been introduced that is accessible when the new *v15-compat*
330 variable is set. If used, credential lookup occurs before a network
333 The new manual section "URL syntax" describes the new credential
334 variable chains, and documentation of *from* should be read again, as
335 i now also refers to the new *smtp-hostname* variable.
337 Note that the generated `Message-Id' has also changed.
339 (Messy old way pointed out by Tarqi Kazan)
340 [topic/url, topic/cred]
342 - `resend' should be truly fixed and (fwiw) can also resend to pipe and
343 file addressees. [topic/resend]
345 - Support for empty lines in macro and account definition blocks (as
346 required by POSIX for startup files in general) [43cdf92]
348 - The nail command line editor gained the possibility to use PgUp /
349 PgDown / Home / End instead of z[-+0$] commands on xterm-compatible
350 terminals; and ^O equals a `dp' there, too. [8c57be2, 7c30e61, 95e672f]
355 Many thanks to Gaetan Bisson.
360 - Avoid segmentation faults with -L option if s-nail is opened on
361 non-existent mailboxes, e.g. '$ MAIL= s-nail -Lx'. (Gaetan Bisson)
367 Thanks and greetings to Gavin Troy, Gaetan Bisson and Tarqi Kazan (tarqi
368 AT cfs DOT dyndns DOT biz).
370 ChangeLog (packager-affine)
371 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
373 - WANT_AUTOCC knows that clang(1) version 1 can dig -Wstrict-overflow=5.
376 - '$ make test' should work even if you are not steffen.
377 (Gaetan Bisson, Gaetan Bisson, Gaetan Bisson, Gaetan Bisson,
378 Gavin Troy, Gavin Troy) [8b796ba]
383 - *autoinc* is gone -- this is *newmail*. [07a8462]
385 - Working with large(r) IMAP boxes should work again without causing
386 segmentation violations. (Gavin Troy) [761dd87, b0ce180]
388 - With our builtin getopt a.k.a. WANT_NOGETOPT=1 usage of the -L option
389 caused segmentation violations. (Tarqi Kazan, Gaetan Bisson) [f2c2646]
391 - The decision wether we need $PAGER or not now also incorporates the
392 informational lines we inject for messages. [316b4cd]
394 - Drop `defines', add `unaccount', rename `undefine'..
395 The `defines' command has been united with `define' -- just like
396 `account' will list all defined accounts when used without arguments
397 `define' will now do so for macros. And `undefine' is the new name of
398 `undef'. The new command `unaccount' can be used to delete all given
399 accounts, in equal spirit to `undefine' and macros.
400 All of this is still vulnerable against recursivity, e.g., deleting
401 an executing macro still works, but don't that. [b0b3275]
403 - Rename `var-inspect' to `varshow'; silly oversight that `var-inspect'
404 will try to lookup a variable "-inspect". Ouch. [afffd30]
406 - Without HAVE_ICONV the character set iterator sofar used
407 *charset-8bit* as the last resort, whereas it should have used
409 P.S.: All this still preliminary, we await the MIME and send layer
410 rewrite to calm down the stuff for real. [edc3226, df9aefd]
412 - During `~@' editing it is possible to leave the possibly endless
413 character set selection loop by interrupting via ^C.
414 In the meanwhile this effectively drops the currently edited
415 attachment and leaves the entire attachment selection session; it
416 doesn't make sense to make it any better until we have our signal
417 manager and stop jumping around.
419 This changeset should also fix dangling Content-Xy MIME information of
420 attachments which were in the same slot before, e.g., if #1 was
421 a message attachment and that was changed on-the-fly to be a real file
422 attachment then the Content-Description would still have stated that
423 it is a message attachment.
426 ChangeLog (purely technical)
427 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
429 - Since it has been decided to remain compatible to ISO C89 we cannot
430 use the ISO C99 `z' format string modifier (printf(3)).
431 Since quite some time we make efforts to provide our own `ZFMT' macro
432 (in `nail.h') which provides somethint compatible, but on 32-bit
433 platforms compilers often complain nonetheless.
434 Therefore we now also have a compile-time assertion that proves that
435 our `ZFMT' macro is really correct. [397e4d1]
440 Many thanks to the perpetual Gavin Troy.
442 - Faulty notational change of system call return values from `<0' to
443 `==-1' caused endless waitpid(2) loop. [d6f316a; test(!): 79fd761]
446 - (GLibC) STD I/O overoptimizes rewind(3) so that underlaying file
447 descriptor offset is not reset to 0. Generalize the already
448 used `really_rewind()' hack and use it not only in
449 `savedeadletter()' but also in `page_or_print()'. It is likely
450 that this not also fixes `history' listing but also some other
451 things which go through the pager, dependend on the setting of
452 *crt* etc., and on at least GNU/Linux systems. [463660f]
454 Note: standard I/O does NOT offer a possibility to do this in
455 a non-hackish way. It is thus likely that S-nail will gain
456 a completely new I/O layer in the future. That'll also be faster.
459 This note is false: POSIX Issue 7 overloaded the meaning of
460 fflush(3): when used on readable streams the file offset of the
461 underlaying file descriptor is adjusted to that of the stream.
462 (nail.h: adjust really_rewind(): POSIX Issue 7 defined a way..)
463 uses this official approach instead if _POSIX_VERSION>=200809L.
465 - Old shells will now correctly execute an error-condition
466 execution path in `mk-conf.sh'. [afef55f]
471 Thanks to Andy Switala (andy DOT switala AT gmail DOT com).
472 And thanks to all package maintainers for their stamina.
474 At the first workday after the release i've run into a bug that was
475 caused by an oversight, a double-Fclose() that would be harmless if we
476 wouldn't forcefully panic() when we encounter it!
478 So i've spent another week on a review, and despite fixing many
479 additional notational oversights i haven't found more oversights of
480 newly introduced problems. On the other hand i've found and fixed some
481 old problems during the review, and tweaked some other things:
483 - The INSTALL file now has a `Current codebase state' section.
485 - Commands invoked via `!' should now be interruptable.
486 I'm afraid the exit status of such a command will not be reflected by
487 the return value of the `!' command yet, but hey, at least `!sleep 10'
488 can now be interrupted -- try this with another Berkeley Mail!
491 - All credential prompts should now be interruptable.
492 (Inspired from Andy Switala) [c3bb2a2]
494 - 'make test' will now test a silly S/MIME case when WANT_DEBUG (or
495 'make devel') was used. [8cff17f]
497 - *batch-exit-on-error* should now look at the exit status of *every*
498 command when the command loop ticks. [c7e7d53]
500 - The new `[?name-list]?search-pattern' search expression has been
501 changed to `[@name-list]@search-pattern' -- like this it doesn't clash
502 with the `?' help command and can thus be used on a line by itself,
503 causing the default command (`next') to be invoked on its' result,
504 shall there be one. Ok, yes, that was surely also an oversight.
507 - *attrlist* must now be exactly 13 characters, just as it should
508 be. An error message is printed if not. It was always komisch,
509 but i'd buggified it somewhen in the past. Now fixed.
512 - The NCL WANT_TABEXPAND feature now also works if *newfolders* is
513 set to `maildir'. Yet, if a folder was assumed to be of maildir
514 type, shell globbing would not occur. [part of f5c184c]
516 - The `X-Decoding-Data' S/MIME header field was set to the epoch
517 origin instead of NOW in v14.6.
519 Also the `certsave' command now supports file globbing (i.e.,
520 '~/.certs/' should end up in your $HOME now).
521 [both part of 7e0aec7]
526 + With this release the S-nail codebase has been converted to my usual
527 style of function-code-flow and notation.

534 Maildir and S/MIME support have been restored, and a MIME bug that
535 could have led to missing data in header display+ has been fixed.
536 Ah, and users of compressed boxes should now feel luckier, too --
537 at least once they've realized that the compress extension is no
538 longer appended automatically, but must be given explicitly.
540 Thus: i hope that all those i-am-new-to-the-codebase bugs i've
541 introduced over a year ago have been found and fixed, and that
542 v14.6 is the true "sweet sixteen" (months of maintainership).
544 ChangeLog (packager-affine)
545 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
547 - If WANT_AMALGAMATION is set, `-pipe' will be added to our CFLAGS
548 (which are only honoured with WANT_AUTOCC, of course). [1330411]
550 - New configuration option: WANT_IMAP_SEARCH, enabled by default.
552 The regular expression support for IMAP-style search expressions has
553 been removed again: it changed the IMAP search semantic in that it
554 couldn't be executed on the server, but only local, and the syntax
555 sucked, too. (And we have a new `?' search expression.) [402b7c6]
557 - CONFIG=MEDIUM and CONFIG=NETSEND now both WANT_REGEX. [dee954e]
559 - The `make test' target should *really* work gracefully, now that usage
560 of the `-#' command line option also sets the folder to be opened to
561 `/dev/null'. (Still no `void' box in sight.) [0119d514]
563 - All published patches may also be found in a new [patches] branch.
568 - Several fixes that saw published patches (with equivalent
569 functionality), and are thus described in NEWS, are included:
571 . s-nail-14.5.2-sort-alt.patch
572 Fixes a hasty commit that introduced string relaxation in a faulty
575 . s-nail-14_5_2-mimeheader.patch
576 Fixes data loss if multiple MIME encoded-words follow each other in
577 header bodies. [c81afce]
579 . s-nail-14_5_2-maildir.patch
580 Effectively restores proper maildir support. [1c2563b, 13f325f]
582 . s-nail-14_5_2-smime.patch
583 Fixes an off-by-one error and, in effect, restores S/MIME sign and
584 encryption etc. support. [e759f75]
586 - The `screen' terminal type is by default recognized as being
587 colour-capable. [e759f75]
589 - With the NCL command line editor and WANT_TABEXPAND hitting <TAB>
590 should now act as if an "implicit asterisk" had been given in case
591 there was no expansion of the original user input; e.g., '? ls <TAB>'
592 may exceed your line limit now ;). [0910a8f]
594 - The S/MIME cipher list was outdated, RFC 5751 requires AES-128 as
595 the default, the RC2 ones are long obsoleted (etc.). Also we now
596 should handle that OpenSSL may not support individual algorithms.
598 Note: we use the option value `des3' for `DES EDE3' from now on!
599 (Maybe see *smime-cipher-user@host* manual entry.)
601 *ssl-method* may now also be assigned the new (default) method `auto'
605 - Messages will now be stored in a set *record* even if only file or
606 pipe addressees were given. [a11935b]
608 - Support for xz(1) compressed mailboxes has been added.
609 (The `Can't canonicalize' warning for compressed boxes had the same
610 cause that made maildir usage impossible, but i don't feel _too_ bad
611 because looking into the code a bit revealed that the *newmail*
612 mechanism never worked for such boxes anyway. And will for a while.)
615 - S-nail now supports nested if..else..endif conditionals. [3c22c04]
617 - The NCL command line editor now locks its' history file when it reads
618 and writes it, so as to protect against concurrent usage. [c3a39ce]
620 - You can now say 'fi%', 'fi&', 'p&10' and `ghost ps '!ps axu'' followed
621 by 'ps|grep nail'. [c3266c6]
623 - Invocation cleanup: usage of -f and -u is mutual, -H and -u is ok, -u
624 in send mode not. [fa0a0aa]
626 - New message specification: `[?name-list]?search-string' will search
627 in locally available messages. If the optional `?name-list' part is
628 given, that specifies the (comma-separated list of) header fields to
629 search in. The special names `body' and `text' can be used to search
630 in message bodies alone and bodies including the headers fields,
631 respectively. Note that "message bodies" unfortunately still means
632 "including headers of attachments and attachments themselves", and
633 until some later time. [61bb460]
635 - The new command line option `-L spec-list' prints a header summary of
636 only those messages that comply to the specification list `spec-list'.
637 If -L and -H are used in combination, no summary is printed at all,
638 but the exit status reports wether `spec-list' would have matched some
639 messages or not. [934e12c]
641 ChangeLog (purely technical)
642 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
644 - Most of the work was changing the code-flow of the entire codebase to
645 my usual style of programming, with a single function entry and
646 a single function exit, including the addition of N(ot) Y(et) D(ead)
647 points of interest, which finally enabled me to get rid of (sic!)
648 using a debugger for S-nail development. Just compile via 'make
649 devel', and in case of a crash you should get a nice backtrace
650 listing. (You use IMAP, do you?)
652 However, because practically every line of code has been touched, this
653 caused some other changes along the way, e.g., the handling of
654 temporary files was changed completely (the formerly used Ftemp()
655 function has been replaced with a new Ftmp(), which handles unlinking
656 itself as necessary etc.), it was detected that the S/MIME support was
657 no longer compliant to any RFC, some resource leaks have been
658 eliminated... It is likely that a change so large introduced some
659 other flees and flaws, however. But it looks good so far.
665 + No official release, only exists as git(1) tag.
667 v14.5.2: fix 4: 2014-02-15 (2014-02-14)
668 ---------------------------------------
670 - s-nail-14_5_2-smime.patch
671 Fix a very stupid off-by-one error that i've introduced
672 in [7bdf330] (OpenBSD 5.3: sigh, address strcpy(),strcat()
674 Until we've changed the used data from string to something
675 line-wise, use strcat(3) again.
677 v14.5.2: fix 3: 2014-02-10
678 --------------------------
680 - s-nail-14_5_2-maildir.patch
681 maildir folders would have caused problems in environments which
682 provide the realpath(3) function: beside a "cannot canonicalize PATH"
683 warning the finally used path would be wrong (`test3' would end up as
684 `test3/test3'), so that any further access would try to use the wrong
685 path. Please read the description of this patch and/or the commit
686 logs of the commits [1c2563b] and [13f325f].
688 v14.5.2: fix 2: 2014-02-05
689 --------------------------
691 - s-nail-14_5_2-mimeheader.patch
694 Subject: ehm, .getElementById("blink") needs <span
695 =?US-ASCII?Q?id=3D"blink">,?= not =?US-ASCII?Q?class=3D"id"?=
697 would yet be displayed without the " not " in between the two encoded
698 words because of faulty "encoded-word-continuation" detection (note
699 the quotation marks). The error path could also have been seen in
700 mail forwarding and in faulty searching etc.
701 This patch is in a row of fixes for my hasty [0f9ad93] from 2013-03-12
702 that already caused the v14.2 minor release (because of [b608c6b] from
703 2013-03-14). Those with mercy may read the commit message of [c81afce].
705 v14.5.2: fix 1: 2014-01-30
706 --------------------------
708 - s-nail-14_5_2-sort.patch
709 Reverses (sort(),thread(): use srelax()!, 2014-01-18, [a9b67e9]),
710 which was a hasty commit of an untested diff that i've added few
713 As a rather careless last-minute change i've added string relaxation
714 to threaded and sorted display, but it's really one more step towards
715 lowering memory pressure -- i couldn't resist [a9b67e9] after seeing
717 An alternative, forward-heading patch that keeps string relaxation has
718 been pushed to [master] as [5e75529] and is also available as
719 s-nail-14_5_2-sort-alt.patch.
724 Thanks to Ypnose, Sunil Nimmagadda and Gavin Troy.
725 Gavin Troy *really* deserves special thanks for facing [next]!
726 And i want to dedicate the new coloured message display functionality
727 to John Dodson and Ypnose. Thank you.
728 (And best wishes to beautiful Australia!)
730 ChangeLog (packager-affine)
731 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
733 - All utilities can now be overwritten during configuration so that
734 their values are fixated in the generated makefile (`mk.mk').
735 I.e., talking about MAKE=, STRIP=, awk=, cat=, chmod=, cp=, cmp=,
736 grep=, mkdir=, mv=, tee=.
737 rm= and sed= have to be overwritten from the command line, they're
738 needed before `conf.rc' is read.
739 [5c03347, 072ec65, 39a00ab, 23a1245, ?]
742 - The release tarball is now also available in a xz(1) version.
744 - New configuration option: WANT_COLOUR, by default enabled.
746 - 'make test' should now really work, even if the running user has
747 a mailbox with content. [f223a91]
749 - WANT_AUTOCC is now by default enabled, so as for normal users which
750 don't have the need to embed into a defined packaging environment.
753 - Installation no longer strip(1)s away debug symbols if WANT_DEBUG was
760 - Fixes to some bugs that are present since the first cvs(1) commit of
761 Heirloom mailx(1); includes that *ssl-key-user@host* should now work.
762 [4405a2cc, 9770c26f, 692976b9]
764 - Some off-by-XY fixes, thanks to the debug memory canaries.
765 [19b2b0d, 202506e, 43df6e4]
767 - Fixes for (other) stupidisms (of mine): [1c2161f]
769 This includes true implementation of in-memory history limit for the
770 NCL, which was the final and real solution to a segmentation fault
771 that Gavin Troy had to deal with on [next]. [1089f2b]
774 - For completeness: new command `var-inspect' shows information about
775 all given options. Mostly ment for implementing future tests.
778 - The `pipe' command no longer embeds message information into the
779 data passed through to the command (when *piperaw* is set).
780 [ef5ecc6 (part of topic/colour)]
782 - Simple coloured message (header) display is now possible. Please
783 read the new manual section "Coloured message display", use
784 *colour-disable* to turn it off. (It is enabled by default if it
785 knows the terminal is capable and, if used, the pager can, too. Note
786 we now set LESS=FRXi when starting PAGER and no LESS= is in the
789 Dedicated to John Dodson and Ypnose.
790 [topic/colour, c6e84c7]
792 - The `if', `else', `endif' syntax has been extended.
793 You can now "if 0" (never), "if 1" (always), "if $OPTION" (boolean
794 check for OPTION) and "if $OPTION == 'VALUE'" as well as "if $OPTION
795 != 'VALUE'". Unfortunately it is still not possible to use
796 conditionals inside conditionals. [0fb2ae7]
798 - -# now also sets MBOX=/dev/null. [4be2f1e]
800 - The NCL command line editor now supports cursor keys when the terminal
801 produces xterm(1)-compatible keycodes ('ESC' + '[' + [DACB] for left,
802 up, right and down, respectively). What a thrill, yay!!! [0cbf672]
804 - New (optional) command: `history': show or clear command line history,
805 or select a specific command line from in there.
806 History works a bit different now, and should no longer include
807 command lines which include specific message numbers; more to come.
808 [59c6195, topic/hist2]
810 I plan to join all the history management and use only the one that is
811 part of NCL now, hooking it into editline(3) and readline(3). That
812 would shrink tty.c a bit and also introduce duplicate elimination for
815 - The new ~u and ~U tilde escapes work like ~f and ~m, respectively, but
816 don't include any header lines. Inspired by a patch from
817 Sunil Nimmagadda on openbsd-tech@. [c37b8b3]
819 - The `|' command should work again -- it has stopped working on
820 2013-09-09 when i've accidentally changed the command name from `|' to
824 - As a rather careless last-minute change i've added string relaxation
825 to threaded and sorted display, but it's really one more step towards
826 lowering memory pressure -- i couldn't resist [a9b67e9] after seeing

836 ChangeLog (purely technical)
837 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
839 - We now have debug canaries for all memory sources now that [8419d44]
840 added them to the "string dope".
842 - The most work has been done on our value system, which manages the
843 binary and value options, like *folder* etc.
844 It is now based on enumerations, i.e., constant integers, not on
845 strings. This of course only relates to non-dynamic options.
846 Anyway, this saves us key hashing and allows more compact data
847 representation in general (see the new header `okeys.h' for more).
853 ChangeLog (packager-affine)
854 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
856 - The build system *only* uses the automatically detected $CFLAGS and
857 $LDFLAGS if WANT_AUTOCC=1. I.e., even unset or empty $CFLAGS and
858 $LDFLAGS are not touched until then.
859 (We do however still set $CC if that is unset or empty or set to the
860 plain string "cc".) [856625f6]
865 - Fixed segmentation faults / bus errors when setting *nofolder*
866 / *line-editor-cursor-right* to the null string (only with WANT_NCL),
867 respectively. [d1f1a19b, 21e5c285, 9f6ff25d]
869 - *prompt* handling is now really POSIX compliant (thus no prompting
870 occurs not only for 'set noprompt', but also for setting *prompt* to
873 This was indeed a rather large changeset that also introduced the new
874 *prompt* escape character \&, which expands to `?' by default and to
875 `&' if *bsdcompat* is set.
877 Like that we now can simply assign "\& " to *prompt* at program
878 startup, which (a) allows to do 'set noprompt' without error (once)
879 and (b) allows for POSIX compliance in respect to prompt handling
880 without any complicated conditional code, but (c) gives us the
881 opportunity to continue to support BSD prompts.
884 - For completeness: new command: `features'. (Rather useful for being
885 able to implement more tests in the future, and act according to what
886 is really compiled into the tested binary.
888 - The `-#' command line option now also sets *quiet* by itself.
891 - nail.1: a newly introduced empty line in the manual produced error
892 messages on some systems. Fixed.
894 - The return value of the `mimetypes' command has been reversed and
895 should now be fixed. [acf56ac52]
897 - In threaded display the Subject: followup suppression no longer
898 takes into account invisible messages.
899 Also, rudely hack in a messages-already-written-in-this-round counter,
900 so that the followup suppression knows when "the top of the screen" is
901 reached, which (seems to) help(s) against missing subjects up there as
902 well as after a `newmail'. [topic/subject]
904 - Added a WANT_REGEX=1 toggle in `conf.rc'.
905 When we find regular expressions then a new regex-enabled IMAP-style
906 search is available (see the manual for more) [1ec8fe68]
908 ? f (/or subject ^\[S-nail (subject ^\[nail-devel))
909 ? f (/subject ^\[S-nail) (/subject ^\[nail-devel)
910 ? f (/subject "^\\[(S-nail|nail-devel)")
912 I'm looking forward for being able to add another, simplified, syntax.
914 ChangeLog (purely technical)
915 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
917 - The cc-test.sh has seen some tweaks, for easier future extension, and
918 for adding a test for [d1f1a19]. [several, mentioned: 21e5c285]
920 - On systems without a real wordexp(3) implementations deadlocks could
921 occur because we sometimes hold_all_sigs() to avoid longjmp(3)s away
922 (and will do so for quite some time, still), and that resulted in the
923 SIGCHLD that reported the exit of the started subshell to be blocked,
924 too (e.g., after '? *.h<Tab>': endless hang). Fixed.
929 Many thanks: Gaetan Bisson, William Yodlowsky, Gavin Troy,
930 Thomas (wasd AT gmx DOT net), Ypnose.
931 And Gavin Troy definetely deserves a very special credit.
932 But thank you all, and very much indeed!
934 ChangeLog (packager-affine)
935 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
937 - The `test' make target has been fixed. [f0991e14]
940 - It is possible to gain a different kind of make(1) verbosity by
941 using a VERBOSE=1 command line argument (this knob is not taken into
942 account when deciding wether a rebuild is needed). [498e4ad0]
945 - On Crux 3 Linux and OpenBSD the readline(3) and editline(3),
946 respectively, libraries will now be found when desired. [a7d1aa78]
949 - WANT_LINE_EDITOR has been renamed to WANT_NCL, *plus*.
950 So now there are WANT_READLINE, WANT_EDITLINE and WANT_NLC, each of
951 them can be set individually, and they are tested in the shown order.
952 Also, WANT_TABEXPAND and WANT_HISTORY have been introduced and can be
953 used to fine-tune functionality. [ae4e01e1, b2635feb, 9742bf40]
955 (While here, i've fixed WANT_TABEXPAND code so that it is more
956 sensitive to line excess; on Linux etc., where MAX_INPUT is 255,
957 strange behaviour could be seen because we didn't take into account
958 the length of the prompt at all. The NCL is assumed to have only
959 one remaining, but unfixable problem: backspace often is incapable
960 to cross visual line boundaries; use ^A/^E + ^L, then. [e832c04a]
962 Also, cursor (now ^B and ^F) and history movement (now ^P and ^N) of
963 the NCL have been changed. [d7d928da])
965 - WANT_QUOTE_FOLD is now enabled by default. And WANT_ASSERTS has been
966 renamed to WANT_DEBUG. [1e10da1f]
968 - The build system has seen yet another overhaul in general. CC, CFLAGS
969 and LDFLAGS plus are now tracked and changes will force rebuilds.
970 The new WANT_AUTOCC option can be used to let the build system figure
971 out a compiler and choose known-to-work flags. Use the new ADDCFLAGS=
972 and ADDLDFLAGS= command line arguments to add your specific flags on
973 top of those -- the final CFLAGS etc. are what is change-tracked.
975 This rather massive internal rework revealed that old Bourne shells
976 were yet not supported by the new build system, and so did testing
977 that UnixWare installation was yet impossible due to tool
978 incompatibility. [75c4b74e]
980 - The new WANT_AMALGAMATION option will force compilation of all the
981 sources in a single compilation unit. This requires a rather large
982 amount of memory, but may produce a more compact, maybe more optimized
983 binary. (Implementing this revealed quite some bugs which could
984 therefore be fixed.) [topic/amalgam]
986 - `nail.rc' has been pimped a bit (mostly comments, but
987 *mime-counter-evidence* is now always set). [e3094ba7]
989 That changeset was however buggy. [f3dcb46]
992 - We no longer use install(1) for `install'ation make rules. [80b02cd9]
997 - Even '$ s-nail & fg $!' will now work with the NCL. [2a8b5c55]
999 - Several off-by-one (off-by-two) fixes. [32ce9836, 71e6d013, f139dc36]
1000 (Gavin Troy, Thomas)
1002 - Setting *noprompt* now prevents prompting, as per POSIX. [ecefaf63]
1004 - *prompt*: new \$ (exit status of last command) and \@ (name of
1005 currently active mailbox) escape sequences. [6f652046]
1007 - One may now omit the space in '? unc' ('?unc') [05fcb383]
1009 - New commands: `ghost' and `unghost' define command aliases (since
1010 `alias' is taken for a different purpose) [topic/commands]
1012 ? ghost ps '!ps axu'
1015 - There is now a pseudo account `null' (case-insensitive).
1016 Also a new `localopts' command exists; when used from within an
1017 `account' block, options changed will be reverted back to its former
1018 value when the account is left (e.g. by switching to `null'):
1021 alternates sdaoden@users.sf.net sdaoden@users.sourceforge.net \
1022 sdaoden@googlemail.com sdaoden@gmail.com
1023 set Sign="\n--steffen\nForza Figa!" sign="\n--steffen"
1024 set smtp=smtp.gmail.com smtp-auth=plain smtp-use-starttls
1030 set from="Steffen \"Daode\" Nurpmeso <sdaoden@gmail.com>"
1035 set from="Steffen \"Daode\" Nurpmeso <sdaoden@users.sf.net>"
1043 neither of *Sign*, *sign*, *smtp** nor *from* should be set.
1044 Please see the manual for more.
1045 TODO - neither command-ghosts nor alternates etc. are yet tracked
1046 TODO - we should have a boolify() so as to say 'localopts yes' etc.
1049 - New command: `cwd' (print current working directory).
1050 Also fixing the `chdir' return value. [eff4397c]
1052 - The *ssl-method* now allows explicit setting of 'tls.1.1' and
1053 'tls1.2' values. [c66b4196]
1055 - When sending to display, be aware that filenames in MIME parts may of
1056 course be MIME-encoded! [1454be03]
1058 - *hostname* is now honoured even if *smtp* is not set. (We always
1059 supported *from*, so why not *hostname*?)
1061 - The `-u user' option now acts identically to setting the $USER
1062 environment variable and both now tend to mean something like
1063 "impersonate as user in some aspects". Note that we have always used
1064 the latter in one or the other way, and `-u user' always ment more
1065 than just "open mailbox of user", so i think this change sharpens the
1066 edge in the right direction. [09632731]
1068 - Filename argument quoting has been tweaked for (some) function(s which
1069 take a filename argument last). The following snippet as reported by
1070 Gavin Troy should work now: [2bb9b80e]
1072 ? mv +inbox.Junk\ Mail
1074 - The GNU implementation of wordexp(3) is also (i've added a workaround
1075 for the very same bug for Mac OS X in S-nail v14.3 [63273772]) buggy,
1076 which causes segmentation faults when expansions failed (`fi &VOID').
1080 - The `fi' command no longer uses the (possibly truncated) display
1081 version of a filename, but the full path. [5cd85b07]
1083 ChangeLog (purely technical)
1084 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1086 - Large rework of internal structure: bundle inclusion of most of the
1087 external and the content of most of the internal #include files in the
1088 new nail.h. If that would have been done very first bugs like the
1089 infamous MAXPATHLEN bug as reported by Paul Vojta (see v14.4.2) would
1090 never have occurred. [21f3155b]
1092 - Support for -fstrict-overflow cc(1) flags. [topic/strict-overflow]
1094 - Fixed the quotation filter which yet allocated memory even if not
1097 - String relaxation reduces memory pressure rather drastically when
1098 working with many (especially MIME) mails at a time, e.g., when
1099 writing a modified mailbox. Before all messages of a mailbox had to
1100 be worked without releasing any memory in between, now we give back
1101 memory (to our pool, not the system) after each and every message.
1104 - The other memory source now uses bound canaries, which also found some
1107 - We now use the EL_PROMPT_ESC editline(3) mode for prompting, which
1108 should offer the possibility to use coloured prompts etc. with
1109 (even those) editline(3) (versions which do offer it -- older versions
1110 should just do fine by themselves).
1111 S-nail uses the special trigger control character \1. [ea30d818]
1114 Note however that all tested editline(3) versions are buggy and
1115 either don't get it right (`\1COLOR-ON\1stuff\1COLOR-OFF\1') or are
1116 incapable of proper repainting (`\1COLOR-ONstuffCOLOR-OFF\1').
1118 - We now use the MD5 digest code from the OpenSSL library if that is
1124 Many thanks: Gaetan Bisson, Stephen Isard, Jérémie Courrèges-Anglas,
1125 William Yodlowsky, and Adam Sjøgren from GMANE.org!
1127 ChangeLog (packager-affine)
1128 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
1130 - The packager-install: target has been fixed. [a8c1b0b]
1131 (Gaetan Bisson and William Yodlowsky)
1133 - As suggested by Gaetan Bisson the several build system tasks are now
1134 individually addressable, i.e., 'make [OPTIONS] config', 'make build',
1135 'make test', 'make packager-install'); nothing changes unless you want
1136 to, in which case: please see INSTALL. [4d3b799]
1138 The new target 'test' will call cc-test.sh with its new --check-only
1139 option which will only perform the (too few) function tests on the
1141 And cc-test.sh will no longer create output files, but simply echoes
1142 to STDOUT and STDERR. [629e1ee, 786f219]
1145 - The default configuration file now sets *bsdannounce* and *bsdflags*,
1146 all in one line, as suggested by William Yodlowsky.
1147 (If *header* is disabled, *bsdannounce* is ignored, but *header* must
1148 be enabled by default according to POSIX, and *bsdannounce* is just
1149 the same as *header*, but for the folder-switched event. Thus setting
1150 *bsdannounce* is the more sane default, imho.) [6161f10]
1153 - Announcement messages are now tagged '[ANNOUNCE]'. [26e1b35]
1154 (Tagging suggested by Stephen Isard and Jérémie Courrèges-Anglas)
1156 - The manual NAME now includes the version (but it's somewhat ugly).
1162 - When switching folders when in compose mode, message attachments
1163 become invalid. For v14.4.5, at least warn when this happens.
1166 - When reading multipart/alternative messages which do not contain
1167 a text/plain part, the (most likely HTML) part is not displayed (even
1168 if S-nail is configured to display HTML). The reason is a bug i've
1169 introduced with [0d43a999] (Change "Part X:" display message..,
1170 2012-12-20). (Note that the committed fix i've posted to the list was
1171 not correct either and has been fixed itself.) [225c02b, ecfa149]
1176 Thanked, Gavin Troy, Gaetan Bisson.
1178 - Fix output buffer confusion that would have occurred when parts of
1179 a multipart mail had a pipe command set. Longer story in [e75d16dd].
1182 - The makefile now supports a `packager-install' target that bypasses
1183 the reevaluation of the configuration (after checking that there is
1184 one) and directly steps ahead to the install process.
1187 - Notes in INSTALL that CFLAGS and LDFLAGS need to be overwritten from
1188 within (conf.rc or) the command line.
1194 I convey special thanks to Karol Błażewicz and Gaetan Bisson.
1196 - The new build system didn't allow to overwrite CFLAGS= when used in
1197 conjunction with GNU make(1). To make a long story short, removing
1198 a `.POSIX:' directive from the makefile fixed the problem. Luckily.
1201 - More INSTALL notes for UnixWare 7.1.4, which suffers from the same
1202 problem: here the fix is to use the -e option of make(1).
1204 - Karol Błażewicz reported a segmentation violation he got when using an
1205 Arch Linux S-nail test package, and Gaetan Bisson informed me about
1206 that. The problem was that we didn't assign the resulting default
1207 address (which gets used when *from* is not set) to the result which
1208 gets used, effectively resulting in a NULL dereference. [cfd60479]
1213 Many thanks to Paul Vojta.
1215 - On GNU/Linux there is no MAXPATHLEN constant defined by default, as
1216 this is a non-standard legacy constant. Mozilla ran into this some
1217 time ago, though a bit different [1]. It made it easier for S-nail.
1219 [1] <https://bugzilla.mozilla.org/show_bug.cgi?id=412610>
1221 We could include `sys/limits.h' to get at MAXPATHLEN, there it is
1222 defined to be PATH_MAX, but let's just include the standard `limits.h'
1223 and ensure MAXPATHLEN ends up >= PATH_MAX. With this condition being
1224 true even FORTIFYd sources won't bail with reported buffer overflows
1225 because realpath(3) expects a buffer of PATH_MAX bytes. [bee5e57c]
1228 - With the builtin LINE_EDITOR, ensure proper interaction with GNU
1229 rlogind(8), which is alone in its quest to set the ISTRIP termios(4)
1232 - Bugfix a codepath that would have prevented compilation when
1233 HAVE_ICONV is not set.
1234 While there, allow to unselect message attachments when using the `~@'
1235 tilde command interactively, which i mysteriously had forgotten when
1236 allowing selection of 'em. (oops?) [4f58ffea]
1238 - It's now easier for packagers to get at debug-enabled CFLAGS; simply
1239 use WANT_ASSERTS=1 (should not be enabled in shipouts, please).
1242 - Fixed a terrible bug that i've introduced in november 2012, that would
1243 have corrupted MBOX files when using the `resend' command. (The
1244 so-called "From_ line" would have been quoted to ">From_ line" instead
1245 of simply being stripped.) [19d449e2]
1247 - Fixed a SIGSEGV for the builtin LINE_EDITOR, that would have occurred
1248 if a history traversal (^B or ^F) would have been continued by
1249 a reverse history completion (^R).
1250 While there, avoid some multiple-beeps-in-a-row that yet occurred due
1251 to code reuse, and document that ^G etc. reset the multibyte state
1254 Also, the expand-on-tab code could have excessed line input maximums,
1255 e.g., after `? /usr/bin/*<Tab>'. This was of course known, but
1256 i wanted to keep it because all tested (modern) terminals "mess up but
1257 won't break", and thus made it possible to use the data, even if it's
1258 visual representation was messed up. The real solution will be much,
1259 *much* more complicated, i.e., show possible *completions*, page-wise,
1260 etc., i.e., just like is known by tab *completion*. This will need
1261 far more time because it doesn't make sense to embed such complicated
1262 code into the current bed.
1263 Now i've chosen to simply don't display excess, but replace the
1264 content with a message that says that there was excess. It simply
1265 looks better. [0320c8ba]
1267 - I've changed the use of `[?]' as a replacement sequence for invalid
1268 / non-displayable characters to `?' (again). There are still code
1269 paths (from the original codebase) which use the real Unicode
1270 replacement character instead, so our display is still not unique.
1271 On the long term the codepath can anticipate in all levels wether
1272 use of Unicode is possible, so that, then, we will be unique again,
1273 using either only `?' or the Unicode replacement character. [faf6380]
1275 - I've anticipated in v15.0 and implemented *quote-fold* as a stream
1276 filter. It is now multibyte safe and takes into account the visual
1277 width of characters, i.e., ideographs etc. It is working almost as
1278 good as an algorithm can work that looks at data linewise, but is yet
1279 experimental and incomplete in that it will break lines even if only
1280 whitespace or a backslash escape follows. It is code that is only
1281 a few hours old, which is why it is not enabled by default. [
1288 - Fix some harmless stylos and typos in the manual and `conf.rc'.
1291 - Ensure *complete* proper cleanup on signal-caused configuration run
1294 - Bugfix: reenable empty configuration variable overrides, as in
1296 $ make install SID= NAIL=mailx ...
1299 - Bugfix: rename the `conf.rc' variables SHELL, LISTER and PAGER because
1300 they clash with the POSIX standard variables of the same names, which
1301 hurts now that the configuration is run through the shell itself.
1302 The configuration names are now XSHELL, XLISTER and XPAGER (ouch).
1305 - nail.rc: comment out some non-portable S-nail(1) specifics, for those
1306 who install this file as mailx.rc or so, somewhere. [3f14b01]
1308 - From now on S-nail will use simple version tags, as, e.g., `14.4.1',
1309 i.e., no more `s-nail-14.4.1'. [a75437d, 183d59c] (Jürgen Daubert)
1311 Also move UAGENT out of `version.h' [f7be5be]
1313 Uh! v14.4 must have originated in a bad dream; good it's vanished.
1318 Thanks to the entire vivid and virile S-nail(1) user community is
1319 proper, especially Stephen Isard, Gavin Troy, Martin Neitzel.
1320 Not to forget Ryan Kavanagh and Ayan George.
1322 Note this time the changes are in reverse order, i.e., oldest first.

1339 9ab4d6b ^5419d6f 'topic/list1'
1340 Slightly tweaked message thread display, fix `:u :r' to mean it
1345 - The default PAGER is now more(1). (But read on.)
1347 - The `echo' command is now compliant, and fully supports XSI.
1349 - The `group' and `ungroup' command aliases have been removed, they are
1350 `alias' and `unalias'.
1352 - We now have the capability of line editing and history.
1353 One may choose from not less than three different implementations:
1354 a builtin editor as well as possible linkage against BSD editline(3)
1355 and also a GNU readline(3) compatible layer.
1356 Please read the new manual section `Line editor'.
1358 Input is now compliant in that an interactive line may be continued
1359 after escaping the newline character with a backslash.
1360 [topic/cledit1] (all of them)
1362 The *prompt* variable may now contain shell escapes, just like the
1363 `echo' command. [0938d8a]
1364 As a special extension the new \? escape, when used within *prompt*,
1365 will expand to the exit status of the last command. [41076d2]
1367 - The POSIX standard environment variables $COLUMNS and $LINES are now
1368 honoured upon startup. [topic/termsize]
1370 - The `help' / `?' commands now support abbreviation, i.e.,
1371 ``$ ? unc'' should now find `uncollapse'. [7b86195]
1373 - The `~' abbreviation that has been introduced as an alias for `call'
1374 is now a real command, not a magic shortcut. [9987289]
1376 - The new variable *quote-as-attachment* can be used to additionally
1377 embed the quoted message as a `message/rfc822' MIME attachment.
1380 - The compose-mode command `~@' will now attach messages from the
1381 current mailbox if given a filename of the style `#NUMBER'.
1382 Please read the corresponding manual section `Tilde escapes', though.
1384 - The `WANT_JUNK' and `WANT_SCORE', as well as Gunnar Ritters junk mail
1385 management have been removed.
1387 Instead S-nail(1) can now support interaction with SpamAssassin, but
1388 sofar only via the spamc(1) / spamd(1) client / server pair of
1389 programs that ships as part of SpamAssassin. The new configuration
1390 directive `WANT_SPAM' controls wether this feature is desired.
1392 Please read the new manual section `Handling spam'.
1393 [topic/spam1] (Martin Neitzel)
1395 (S-nail(1) is now *definitely* floating-point free.)
1397 - The configuration and make system have been overhauled / reorganized.
1398 The configuration is now in `conf.rc', also contains directives like
1399 `PREFIX' etc, and is always read in. However, only those directives
1400 which are not yet set (via environment or command line overwrites) are
1401 incorporated into the set of configuration options. Therefore
1406 will now build S-nail(1) twice, because of the changed configuration.
1408 Note that `WANT_GSSAPI' is now by default disabled, which shrunk
1409 a freshly started s-nail image by more than 30 percent.
1411 We're not finished yet in that there is no dependency graph etc.
1412 Please do read `INSTALL' and `conf.rc'.
1415 - Message selection has been slightly bugfixed in that `:u :r' really
1416 means `:u' AND `:r'. Compared to NetBSD Mail(1) it's still a shame.
1418 Threaded message display has been slightly changed in that within
1419 a thread identical Subject: lines are not repeated. It may not be
1420 perfect yet due to the general list / thread state. [topic/list1]
1422 - If, upon startup, the environment variable `NAIL_NO_SYSTEM_RC' is set,
1423 then the system wide initialization file isn't read, just as if the
1424 `-n' option had been given. [1b31535]
1426 - It is now possible to use CTRL-C during connection hangs. (But in
1427 general error recovery capabilities of the socket related
1428 infrastructure is non-existent, practically speaking.) [45a9f36]
1430 - *quote-fold* has been temporarily disabled, as it is not multibyte
1433 No review for v14.4. And today is Friday, the 13th. Ouuuh!
1438 I should *maybe* should have and want to give prominence to
1439 Martin Neitzel for this, i maybe have misunderstood.
1441 - Bugfix *synchronous* *pipe-** execution..
1443 Well, unfortunately yet another newly introduced bug slept in
1444 S-nail v14.3[.1] -- [a8d724b3, Add @ and @& shell command prefixes
1445 for pipe-MIMETYPE, 2013-05-03] falsely changed the waiting state
1446 for subprocesses, as has shown up by a HTML-only mail on the
1448 'Seems i'm collecting one line fixes in this codebase; this needs
1449 to change in the future.
1454 I want to give prominence to Juergen Daubert (jue AT jue DOT li), who
1455 reported that i've broken plain-old unfancy send mode in 14.3.
1457 + Ok, i'll hope we're out of new errors for the v14.3 series with that.
1459 - New variable: *batch-exit-on-error*.
1460 Only works if the new -# command line option has been given, and will
1461 check the "current" exit status whenever one operation completes
1462 (S-nail returns to the command prompt).
1463 If the exit status implies error (e.g., sending the last message
1464 failed) then we exit forcefully with that error status. (The normal
1465 behaviour is that the status is reset when the command loop ticks.)
1468 - While here again, i've added the new -# command line option.
1469 This is the first step to implement a reliable batch mode;
1470 unfortunately it still selects the users system mailbox on startup,
1471 because we simply cannot go to "no" mailbox for quite some time -- at
1472 some future time we will be able to go to some VOID thing, and then
1473 this will end up as a rather efficient batch mode.
1474 For now it sets *dot*, *emptystart*, *noheader* and *sendwait*, and
1475 also implies the -~ command line option. [7549569]
1478 printf "m ${MBOX}\n~s subject1\nE-Mail Körper 1\n.\n" &&
1479 printf "m ${MBOX}\n~s subject2\nEmail body 2\n.\n" &&
1481 ) | MAILRC=/dev/null "${NAIL}" -n -#
1483 - Also, -N set *header* instead of *noheader*. [7b4a13f6]
1486 - Plain old unfancy invocations like
1489 $ echo bla|s-nail ./FILE1
1491 had been broken (by [522cb3ec]). [260e19d]
1497 Thanks to Gavin Troy (gavtroy AT gmail DOT com) who inspired the @ and
1498 @& pipe-command prefixes.
1503 - S-nail has been registered at Coverity Scan, and the third build
1504 (after topic branches *coverity-444* and *coverity-444.2*) produced no
1505 more errors. (<http://scan2.coverity.com/projects/444>.)
1506 (Then i used POP3 and IMAP and fixed some SIGSEGV. ;) Still didn't
1507 look at S/MIME, Maildir, caches etc... o()
1509 - S-nail v14.3 doesn't produce any spurious linker warnings on
1510 OpenBSD 5.3; all (correct!) use cases of strcpy() and strcat() have
1511 been replaced. [7bdf330, 2c8d7cb]
1513 - This is the first release with a (though very short) review -- i'm
1514 slowly getting comfortable with the code. (But i'm too stupid to
1515 perform reviews on patches, 'always did reviews on C++/Perl/xy
1516 classes. Aaah, how beautiful ... objects.)
1521 - It is now possible to "call" macros without using the `call' command
1522 by prefixing them with a tilde, as in
1531 - Added the *pop3-bulk-load* option.
1532 Yes, there are mailing lists etc. which use plain text email, and,
1533 there, headers are often more data than the body, so it doesn't make
1534 sense to download the headers twice (unfortunately POP3 doesn't
1535 support a BODY command; if only it would support a RETRDELE command..)
1538 And yep, from this changeset on i personally use S-nail even over the
1539 network, no longer my stale and incomplete S-Postman. And i can tell
1540 you, this damn thing is so silent, i always set *verbose* not to go
1541 grazy ... but .. i hate to say it .. the healing will take time.
1543 - POP3 will now try to use APOP authentication automatically; thus the
1544 *use-apop* stuff has been replaced by *pop3-no-apop* options (just in
1545 case there are POP3 servers which advertise they support APOP but in
1546 fact fail to do so; anyone?) [6c3c5575]
1548 - Some IMAP segmentation violations have been fixed:
1550 ? fi imaps://user1@localhost
1551 Password:Interrupt <- CNTRL-C
1552 ? set imap-auth=cram-md5 <- hey, 'forgot to set correct auth
1553 ? fi imaps://user1@localhost
1554 IMAP write error: error:140D00CF:SSL routines:SSL_write:protocol is shutdown
1557 And also, when *folder* was set to an IMAP account but hasn't been
1558 opened yet, and no IMAP account ever has been opened, a string
1559 comparison against a NULL pointer yet caused a SIGSEGV, too.
1562 - `set folder=' now tolerates `%:' and expands PROTOs stuff etc.:
1564 ? short xp %:imaps://user1@localhost
1567 Pure convenience so that it doesn't need to be typed twice (still no
1568 completion in sight...). Note that setting *folder* to a POP3 box
1569 will now be actively rejected. [b12b17f5]
1571 NOTE: while implementing this i've detected another dead-end
1572 miscondition in S-nail -- you really should ensure that your target
1573 folder/box is connected before you leave your current POP3/network
1574 based folder, if there is data to be moved to the target (i.e.,
1575 mbox). This problem will persist for a long time due to the way the
1576 entire codebase functions; i hope i can find a short/mid-term
1577 solution, but the real healing will take years. The mentioned
1578 solution would at least make S-nail interruptable, currently we get
1579 stuck and interrupts are blocked...
1581 - If you're using S-nail on Mac OS X and have seen some segmentation
1582 faults when expanding shell stuff then you may be pleased to hear that
1583 S-nail now works around an Apple bug. [63273772]
1585 - The builtin mime.types have been corrected and a lot of new ones have
1586 been added. New data from
1587 <http://svn.apache.org/viewvc/tika/trunk/tika-core/src/main/resources/\
1588 org/apache/tika/mime/tika-mimetypes.xml>, thanks! [8072fcb6]
1590 - BEWARE: handling of command line arguments has changed a bit!
1592 1. The -D, -d, -E, -i, -N and -v command line options are now
1593 implemented by means of setting the respective option, as via -S.
1594 (This means that from now on resource files can only *temporarily*
1595 overwrite command line arguments.)
1597 2. The -I and -T command line arguments have been dropped.
1598 It seems Gunnar Ritter stopped developing nail/Heirloom mailx once he
1599 started implementing Newsreader functionality. It'll take a long time
1600 until we get there, so for now drop all the Newsreader stuff.
1602 3. Handling of -r has been changed. E.g.:
1604 s-nail -A test -Snoeditalong -r 'La mort est <fem@me>' -d
1605 ? set from=bummer@m1.com
1609 Sendmail arguments: "sendmail" "-i" "-r" "fem@me" "t1"
1610 ? set from=bummer@m2.com
1613 Sendmail arguments: "sendmail" "-i" "-r" "fem@me" "t2"
1617 s-nail -A test -Snoeditalong -r '' -d
1618 ? set from=bummer@m1.com
1622 Sendmail arguments: "sendmail" "-i" "-r" "bummer@m1.com" "t1"
1623 ? set from=bummer@m2.com
1626 Sendmail arguments: "sendmail" "-i" "-r" "bummer@m2.com" "t2"
1628 [*main-fun-cleanup* topic branch]
1630 - *smime-sign-include-certs-** stuff works again, oops.. [9a8597c6]
1632 - A whole lot of smallest and small fixes due to registration at
1633 Coverity Scan, as project 444. Error handling in S-nail is ridiculous.
1634 [*coverity-444* and *coverity-444.2* topic branches. The sheer number
1635 of fixes was the reason to sit down and go for unplanned S-nail v14.3]
1637 - *idna-strict-checks* has been dropped. It's silly to have in a MUA,
1638 especially given that GNU LibIDN doesn't ship with a lot of rules.
1639 We were able to drop quite some code (and a use-after-free, too :().
1642 - The ~p tilde command displays attachments more verbose.
1643 Until the big big MIME and send layer rewrite :) this is intermediate
1644 since until then we do not really know neither MIME type nor charset
1645 of an attachment at the time this is displayed (for sure). Yet
1646 i think it's nicer to show what we have than keep it the way it was.
1649 - @ and @& shell command prefixes have been added for the pipe-MIMETYPE
1650 mechanism. The former suppresses filters if multiple messages are
1651 displayed at once, the latter adds asynchronous program execution on
1652 top of that. E.g., to display PDF documents, but only if you
1653 *explicitly* address the message *alone and by itself*, and without
1654 blocking S-nail and the $PAGER, do:
1656 set pipe-application/pdf="@&cat >"${TMPDIR}"/s-nail${$}.pdf;\
1657 mupdf "${TMPDIR}"/s-nail${$}.pdf; rm "${TMPDIR}"/s-nail${$}.pdf"
1659 (Inspired by Gavin Troy.) [a8d724b3]
1661 Note: most of that had been posted to nail-devel@ already, but it was
1662 tweaked ([251b636]) so that you now *really* have to say `p MSGNO' to
1665 - The NETLESS CONFIG= has been removed; it is almost identical to
1666 MINIMAL now (i.e., without WANT_JUNK and WANT_SCORE).
1668 - WANT_JUNK and WANT_SCORE have been disabled by default.
1669 They don't seem to be too useful; i hope i can implement
1670 a SpamAssassin hook for (downloaded) mail messages for v14.4.
1671 If so, expect these two "modules" to become removed completely.
1676 Another unplanned (minor) bugfix release after Gavin Troy (gavtroy AT
1677 gmail DOT com) pointed out that MIME CTE decoding was broken, who
1678 i therefore want to give a lot of prominence right here.
1680 - Fix MIME content decoding which has been broken by [01c0e135].
1687 An unplanned (minor) bugfix release after i've found two bugs today and
1688 heard from Jérémie Courrèges-Anglas (jca+nail AT wxcvbn DOT org) that
1689 there exists a S-nail OpenBSD package.
1691 I want to give prominence to the following people that helped to
1692 improve S-nail(1) during this development cycle, in order of
1693 appearance: Dirk Peters (peters AT schwertfisch DOT de).
1695 Thank you very much, and best from Germany!
1697 - Some warnings of newer clang(1) versions were silenced, including yet
1698 another alloca(3) problem (see *memtracer* topic branch in v14.0
1701 - Tweaking the MIME boundary detection left a little hole that could
1702 cause boundaries not to be detected, as has been shown by a Microsoft
1703 Word generated mail on the ICU list. [11e5fb5b]
1705 - A format string could overflow bounds if unrealistic
1706 (18446744073709551615) line numbers or message sizes would have been
1707 produced. [faa65c40]
1709 - An algorithmic error could cause overlong lines which wrapped around
1710 to the next display line. [ade52660]
1713 v14.2, 2013-03-15 [v14.1, 2013-03-12]
1714 -------------------------------------
1716 I want to give prominence to the following people that helped to
1717 improve S-nail(1) during this development cycle, in order of
1718 appearance: Martin Neitzel, Christos Zoulas, Stephen Isard, jgw@txo.org
1721 Thank you very much, and best from Germany!
1723 + v14.2 differs from v14.1 only by one commit, one that fixes
1724 (mime_fromhdr(): partial rewrite using n_iconv_str(), 2013-03-12),
1725 which i hastily implemented just hours before the release of v14.1,
1726 and simply shouldn't have made it (into there).
1727 The v14.1 tarball has been removed from the server.
1729 - A fix for the quoted-printable codec: "message truncation" occurred
1730 when a mail maliciously used a soft linebreak to escape the linebreak
1731 of a completely empty line.
1732 (That resulted in 0 written and 0 leftover bytes, a condition that was
1733 declared erroneous back in november 2012 when i started handling I/O
1736 - The "folders" command will work again when given an argument.
1737 A fault of mine introduced in (cmd1.c: expand() may fail, 2012-10-23).
1739 - The Base64 codec has been touched again, and we are finally capable to
1740 perform sequential decoding; this was targeted for the MIME/send layer
1741 rewrite, but it actually was possible today.
1742 The result as seen in ps(1), running on the Base64 encoded HTML5
1743 standard (4622545 bytes HTML, with a NUL appended to force Base64

1749 (So the only thing that is left for a good throughput is sequential
1750 decoding of quoted-printable encoded parts that maliciously use soft
1751 linebreaks to convert an entire part to a single line. And i've seen
1752 that from Apple Mail.)
1754 - New option: *mime-allow-text-controls* (rather long manual entry).

1761 - Most *headline* formats now do support the '-' left-alignment flag.
1762 Note that you most likely have to change your *headline* accordingly.
1763 (The still missing %n format is one reason why there will be v14.2.)
1765 - *datefield* and *datefield-markout-older* can now be set to
1766 strftime(3) format strings (except %n).
1767 (From Stephen Isard's wishlist.)
1769 - A possible SEGV has been found and also fixed by Stephen Isard.
1770 (The "legendary" cross-world stereo fix!)
1772 - Wow! S-nail will finally compile on GNU based Linux systems like
1773 Slackware 14 etc. (Found while hunting bug reported by
1776 - New option: *datefield-markout-older* can be used to choose
1777 a different date display for mails that are older than six months,
1778 in equal spirit to what POSIX describes for the -l option of the ls(1)
1779 command (Stephen Isard).
1781 - (Exotic) Years are (would) now (be) interpreted correctly according to
1784 - CRAM-MD5 usage has been fixed.
1786 - *folder* updates are now tracked when set, and we will show the
1787 realpath(3) name of it, showing PREFIX..SUFFIX if that wouldn't fit on
1789 Tracking updates made it also possible to perform other more expensive
1790 tasks when setting *folder*, so that it is now possible to do
1796 et cetera (both ideas by Christos Zoulas).
1798 - Bugfix for the ~@ tilde-escape in non-interactive mode.
1799 (readtty(): quick shot: work in pipelines (on non-TTY).., 2013-01-25)
1800 introduced the possibility to "read data from the terminal" (STDIN
1801 that is) in non-interactive mode.
1802 The manual documents that attachment input must be terminated with an
1803 empty line, but if that had been omitted, as in the example below, we
1804 would have yet entered an endless loop.
1806 $ cat <<_EOT | /s-nail -~ -s boom ./OUT
1812 - Alias expansion will now be performed for members of Reply-To: fields
1815 - Decoding quoted-printable will now be more relaxed.
1816 (Even though the standard says that users should be given a hint when
1817 input is not absolutely clean; a possible warning will be added later,
1818 when we have an error message ring.)
1820 - New option: *mimetypes-load-control* can be used to control which of
1821 the mime.types resources will be loaded.
1823 - The builtin default mime.types have been extended a bit.
1828 I want to give prominence to the following people that helped to
1829 improve S-nail(1) during this development cycle, in order of
1830 appearance: John Dodson, Gianluca Ramunno, and Anon Ymous from the
1836 - Encoding defaults to *quoted-printable* not *8bit*.
1837 This has no technical background except that i think it's the better
1840 - Small progress for the "getting stuck due to the current folder
1841 becomes inaccessible due to whatever reasons" problem.
1842 (schdir(): realpath() local files before leaving CWD.., 2013-01-08)
1844 - The names of temporary files have changed. Whereas not all uses of
1845 temporary files already use really meaningful names, it has yet become
1846 possible to use the pattern "*mail-*"; or, to be compatible with
1847 NetBSD Mail(1) in one go, "*mail*". (E.g., in my ~/.vimrc you'd read:
1848 :au BufRead,BufNewFile *mutt*,*mail* setl fenc= | setf mail
1849 [the *mutt* is a leftover from times when i've used MUAs that suck].)
1854 - The Quoted-Printable MIME handling has been rewritten completely.
1855 We now correctly encode files with the MS-DOS newline sequence (CRLF).
1856 (Part of the *mime-cte* topic branch.)
1858 S-nail(1) continues to be able to handle text messages and text
1859 attachments without a trailing newline, but because these
1860 Content-Transfer-Encoding related things are now handled by the C-T-E
1861 layer instead of by sendout.c a text message body that comes in as
1862 part of a complete message via the -t command line option will loose
1863 the missing final newline (i.e., it'll gain one).
1864 This problem does *not* occur when *only* the message body comes in
1865 via STDIN, as in 'cat FILE | s-nail', but *only* when the -t option is
1867 (sendout.c: does no(t/ longer) know about CTE internals!, 2013-02-09)
1869 - Filename arguments for -a are now processed *after* all the resource
1870 files have been loaded etc., so that the usual "folder" specifics can
1871 be used (provided that proper care for shell quoting was taken).
1872 ((main(): delay -a processing.., 2013-01-10), as a part of the
1873 *mainaflags* topic branch.)
1875 - (d38c5bd, When the write command asks.., 2004-11-23) added support
1876 for pipes when saving attachments during a "write" command.
1877 It however used the wrong SIGPIPE signal handler; e.g.:
1879 Enter filename for part 2 (application/x-gzip): |exit
1882 Of course, it still performs a jump and that most likely leaves memory
1883 chunks behind, thus causing some memory leaks. This will be
1884 a long-term problem (you may want to read [mime.c:fwrite_td(): TODO
1885 notes on unfixable leaks, 2013-01-14] for more).
1886 (send.c:sendpart(): fix longjmp() SIGSEGV.., 2013-01-29)
1888 - Fixed a name quoting regression that i've introduced in
1889 (Rewrite *extract().., 2012-10-20), that would have caused
1890 "x \"y\" z" to become "x"y" z" instead of "x "y" z".
1891 (S-nail still does not really have RFC compliant parsers, just as
1892 NetBSD Mail(1) has, i.e., there are structured and unstructured fields
1893 etc... I hope i can provide them in v15.0.)
1894 (names.c:yankname(): fix quote regression.., 2013-01-29)
1896 - The IDNA conversion now assumes domain names are specified in
1897 *ttycharset*, rather than in the LC_CTYPE locale charset.
1898 I.e., it integrates into the usual character set specifications.
1899 (IDNA: honour *ttycharset* for domain names, 2013-01-18)
1901 - The new *editalong* variable will automatically spawn an editor when
1902 composing a mail in interactive mode, just as if `~e' was given.
1903 (Add new *editalong* variable, 2012-01-07)
1905 - The manual has been converted to mdoc.
1906 (The manual has been converted to mdoc, 2012-12-28)
1908 - The ~@ tilde escape, when given filename arguments, will treat the
1909 arguments as a comma-separated instead of a whitespace-separated list.
1910 (collect: change separator of ~@ tilde escape.., 2012-12-28)
1912 The interactive mode of ~@ has also been changed, rather massively.
1913 Please do reread what the manual says.
1914 ((collect: support multiple attachment charsets.., 2013-01-23), as
1915 part of the *attach* topic branch.)
1917 - Thanks to Gianluca Ramunno (ramunno DOT gianluca AT gmail DOT com)
1918 S-Nail will no longer try to issue a STARTTLS command when it is about
1919 to establish a SMTPS connection, a task that logically fails since the
1920 connection is already secured.
1921 (Interestingly the nail codebase performs the necessary test for IMAP
1923 While here the undocumented nail v11.0 *smtp-use-tls* legacy option
1925 (Fix SMPTS with a set *smtp-use-starttls*.., 2012-12-22)
1927 - The RFC 4155 compliant MBOX quoting is now exclusively used, the
1928 shitty *posix-mbox* variable has been removed again.
1929 (Shitty because i've implemented RFC 4155 compliant MBOX quoting and
1930 tested it, then added *posix-mbox* for those who liked the old
1931 behaviour and did not re-test -- the final code path was buggy.)
1933 In mails newly created and saved by S-nail(1) no From_ quoting at all
1934 will be used no more, but instead the rewritten MIME file classifier
1935 will detect unquoted From_ lines and enforce quoted-printable encoding.
1936 (This is an approach that is S/MIME compatible all through the way as
1937 the file data is not modified at all, but only encoded, so that the
1938 data checksum is not changed.)
1940 In yet existent mails that S-nail copies or moves around without
1941 reclassification an RFC 4155 compliant From_ line detector will apply
1942 MBOXO quoting (prepend a single '>') as necessary.
1943 Different to the old MBOXRD behaviour S-nail will neither quote yet
1944 quoted From_ lines ('>>From xy' -> '>>>From xy') nor will it unquote
1945 one quote level when reading etc. mails ('>> From xy' -> '>From xy').
1946 As a result the code could be simplified.
1948 This changeset also incorporates a fix for NetBSD PR bin/47453, as
1949 reported by Martin Brandenburg. I.e., some mailers, noticeably
1950 UW-imap (with MBX format only?), use non-compliant From_ lines with
1951 RFC 822 date specifications. Be aware of 'em.
1952 (RFC 4155 MBOX, and drop *posix-mbox* and foldergets().., 2013-01-06)
1954 - *rfc822-show-all* has been removed.
1955 It didn't work properly for more complex MIME structures, like
1956 message/rfc822 messages with attachments etc., just as i've seen today
1957 on the file(1) mailing list.
1958 So, instead of hacking it now i've dropped it and will come back with
1959 a better solution when the MIME and send layers have been overhauled.
1960 I.e., the real intent was to be able to specify that an embedded
1961 message/rfc822 is treated as a *unity*, and that's the goal.
1962 (Drop *rfc822-show-all*, 2013-01-23)
1963 [The manual will be adjusted in a different commit.]
1965 - *rfc822-no-body-from_* has been renamed to *rfc822-body-from_*.
1966 It thus must be set explicitly.
1967 On the other hand it now catches all cases...
1968 (*rfc822-no-body-from_* -> *rfc822-body-from_*, 2013-01-23)
1969 [The manual will be adjusted in a different commit.]
1971 - The new *charset-7bit* (defaults to US-ASCII) and *charset-8bit*
1972 (defaults to UTF-8) have been introduced.
1973 These are used if seven bit clean data is to be sent, and no
1974 *sendcharsets* are set or the convertion of all of them failed,
1977 - There is no functional change unless there is iconv(3) support.
1978 - There is no functional change unless you set them.
1979 (Introduce *charset-8bit* and *charset-7bit* variables.., 2013-01-18)
1980 [The manual will be adjusted in a different commit.]
1982 In addition the new *sendcharsets-else-ttycharset* variable can now
1983 be used to automatically use *ttycharset* as a *sendcharset(s)*,
1984 regardless of the new *charset-8bit* variable.
1985 (Add *sendcharsets-else-ttycharset* variable, 2013-01-24)
1986 [The manual will be adjusted in a different commit.]
1988 NOTE: before we apply charset conversion we now perform a string
1989 comparison to see wether character sets are identical. If the strings
1990 match (case-insensitively), then *no* conversion is performed.
1991 This means that code like
1993 $ printf "LATIN1: \0376" | s-nail -Ssendcharsets= -s boom ./out.txt
1995 *succeeds* in an UTF-8 environment now, whereas older versions would
1996 fail with an "illegal byte sequence" error (unless the iconv(3)
1997 library of the system would not perform any conversion that seems
1998 superflous, of course).
2000 I thought about making this optional, but, in fact, if this would be
2001 done in an environment without iconv(3) support then the result would
2002 be equally corrupt. And the way it is now we save the expensive and
2003 superflous conversions. (See TODO for more.)
2005 Please *do* reread the manual section "Character sets".
2006 +++++++++++++++++++++++++++++++++++++++++++++++++++++++
2008 - An attempt was made to improve MIME Content-XY: detection.
2009 It should be more RFC compliant, and just overall better :);
2010 a simple one-pass classifier cannot match libmagic(3), of course.
2012 This changeset removes support of the long obsoleted (4fee1ef,
2013 2005-01-06) *charset* variable, as well as for the
2014 *maximum-unencoded-line-length* variable that has been introduced in
2015 (48a652bd, 2005-07-26).
2017 For S-nail v14.0 it'll be no longer necessary to do
2019 $ tr -d '\015' < input | s-nail ...
2021 to transport files which use the $-DOS (terminal) newline (sequence).
2022 We still depend upon *sendcharsets* for a while, though.
2023 (Rewrite file-content classification.., 2013-01-02)
2025 - The new *mime-counter-evidence* variable can be used to force
2026 a classification of non-text MIME parts (attachments) by their
2027 filename, i.e., a "reverse-classification" just as would be performed
2028 if S-nail(1) would itself *send* the file(name). This can help
2029 against some stupid MUAs (Apple Mail?) that send .diff etc. files as
2030 `application/octet-stream' parts etc.
2032 At a later time this may become a valued option, causing a temporary
2033 save of unnamed attachments followed by a MIME classification of the
2034 file contents, followed by forced treatment as plain text if it seems
2035 to be human readable. But not yet. Just to warn you.
2036 (Add *mime-counter-evidence* variable.., 2012-12-29)
2038 - The special "pipe-" command "@" can be used to force treatment of
2039 a MIME message part as plain text (e.g.,
2040 'set pipe-application/pgp-signature=@' will henceforth print those
2041 signatures inline and as plain text).
2042 (Introduce the special "@" "pipe-" command, 2012-12-27)
2044 - The MIME types (as from mime.types(5)) will now be cached. Before
2045 all possible sources would have been opened, read and parsed for each
2046 and every message part that required detection of the MIME
2048 The new "mimetypes" command can be used to show or clear that cache.
2049 (Add mime.types(5) cache.., 2012-12-27)
2051 - A small set of MIME types (template: ./mime.types) will now become
2052 compiled into S-nail(1), and be used as a fallback if there are no
2053 ~/.mime.types and/or no /etc/mime.types, or those didn't contain
2054 a matching type. E.g., NetBSD 6 doesn't ship a default database.
2055 Also, file extensions will be matched case-insensitively (case of
2056 attribute values is not specified afaik?).
2057 (Introduce compiled-in mime.types(5).., 2012-12-21)
2059 - The undocumented *charset7* variable was removed.
2061 - The "Message X:" display leader has been changed and will henceforth
2062 be matchable via "^[-- Message \d+ -- \d+ lines, \d+ bytes --]:$".
2063 These lines can no longer be suppressed by setting the *quiet*
2064 option (which was yet possible for print and top, though undocumented).
2065 (Change "Message X:" display message.., 2012-12-20)
2067 - When displaying multipart messages the "Part X:" introductional string
2068 has been changed; if the Content-type: header is not *retain*ed, then
2069 this string will include the part's type and size. Ditto for
2070 Content-disposition: and a mentioned attachment filename.
2071 This is a first step only, for the final version the MIME and send
2072 layers will have to be adjusted. But the string will be matchable via
2073 a "^[-- #.* --]$" regular expression from now on.
2074 (Change "Part X:" display message.., 2012-12-20)
2076 - MIME boundaries in multipart messages are now handled better in that
2077 no boundary string should get through to the display.
2078 (Tweak MIME boundary detection.., 2012-12-20)
2080 - A couple of long standing, even pre-Heirloom mailx(1) memory leaks and
2081 segmentation violations, most of them related to configurations
2082 without alloca(3) support, as well as one leak that i have introduced
2083 when i implemented RFC 4155 MBOX handling, have been fixed.
2084 But S-nail should now survive non-alloca(3) configurations.
2085 (*memtracer* topic branch.)
2087 - The Base64 MIME handling has been rewritten completely.
2088 This was an urgent topic, because the old implementation (a) read in
2089 all lines of a base64 encoded text part, repeatedly resizing a string
2090 storage and repeatedly decoding that string until all the lines have
2091 been swallowed (i.e., or by accident the last decoded byte was
2092 a newline character, and that in turn may of course have fucked up for
2093 multi-octet encodings, dependent on the actual byte-order), (b) used
2094 function local static data to keep state in between multiple
2095 invocations, which messed up multi-byte/-octet encodings like this
2097 �5��ɽ���Aɥ����́��٥��������[lots of data follows]
2099 and (c) did not perform any error checking at all.
2100 The new one does not run into the problem that (a) tried to circumvent
2101 since leftover decoded data (as opposed to leftover *encoded* data) is
2102 transported along the call-chain for later use. It adds a minimal set
2103 of error handling ('may now see "[Invalid Base64 encoding ignored]"),
2104 with more to become possible in later S-nail versions when the entire
2105 layers are reworked. (Until then DOS newline sequences [CRLF]
2106 embedded into base64 will no longer be decoded to Unix LF newlines.)
2107 Base64 encoded lines will now be 76 characters long, as stated (as
2108 a maximum value) in RFC 2045, not 72 as before.
2110 The Base64 code core has been shamelessly stolen from NetBSD's
2111 Mail(1), and i guess it was the second time that this happened :=).
2112 (*base64-rewrite* topic branch; and reworked later on the *mime-cte*
2115 - The string allocation strategy has been tweaked some more to, i think,
2116 a final version (regarding algorithm).
2117 In normal non-interactive send mode it should now no longer need any
2118 dynamic memory at all (unless some dozen recipients are specified).
2119 (Several other places still use normal dynamic memory, of course.)
2120 (*dope-stringdope-again* topic branch.)
2122 - Support for NSS (Network Security Services) has been removed.
2123 I've never worked with it and are, regarding the complexity of
2124 network security, not willing to spend any time on it.
2125 SSL is installed on all systems i'm using and/or testing on by
2126 default, and so i've choosen to go this way.
2127 (It may be that sometime in the future S-nail will add support for
2128 libcurl(3) connectivity, and then it may happen that not only NSS
2129 support is reintroduced again, but also GNU TLS. All of that applies
2130 to network connectivity only, however, not to S/MIME afaik.)
2131 (*drop-nss-support* topic branch.)
2133 - I finally got a glue and understood that Sourceforge does (a) not
2134 support symbolic links and (b) doesn't like dots as regular parts of
2135 filenames. This means that all this time the promised s-nail.tar.gz
2136 symbolic link did not work, and that s-nailv13.3.tar.gz wasn't
2137 accessible either (via the web interface).
2138 In the future S-nail(1) will not provide any more symbolic links (the
2139 Sourceforge website offers a "download latest" thing which seems to
2140 work), and use underscores in filenames -- s-nailv13.3.tar.gz has been
2141 renamed to s-nailv13_3.tar.gz. The tags continue to use dot notation.
2144 - The *heirloom-plus* support branch has been removed.
2145 The code bases diverged a lot and even more to come.
2146 It doesn't make sense to put any effort in that.
2151 - Configuration on UnixWare 7.1.4 will succeed (shell issue fixed).
2153 - Even on DragonFly BSD the IMAP GSSAPI is now found
2154 (in /usr/pkg/include/krb5/gssapi/gssapi.h).
2156 - Support for pkgsrc(7) systems and automatic integration of
2157 C_INCLUDE_PATH and LD_LIBRARY_PATH path configurations.
2160 - Fixes a mortally embarassing regression that the current maintainer
2161 introduced before i really knew what i was doing, in (If *record* is
2162 set, avoid writing dead content twice.., 2012-09-14).
2163 It hit users that send through a MTA and have *record* set; in this
2164 combination data would not have reached the MTA.
2165 Interested parties may read the comment in savedeadletter() (part of
2166 the changeset) or the (Fix MTA/*record* descriptor clash..,
2167 2012-11-10) commit log.
2169 Deepest apologies to tortured users from the current maintainer!
2171 - RFC 4155 compatible MBOX file handling has been introduced, and so
2172 S-nail is now on par with (at least) NetBSD Mail in respect to this.
2173 It can be turned off with the new *posix-mbox* variable, which you may
2174 need to use since not all MUAs are capable to dig those MBOX files.
2175 E.g., less cutting-edge (.-) MUAs fail for this:

2192 I'm not completely happy since S-nail *does* still quote those lines,
2193 how rare they may be -- it *does* modify message content. mutt(1)
2194 implements something more clever and that is quoted-printable encoding
2195 of the "F" from "From", when seen at the beginning of a line.
2196 This, when applied to just *any* "^From", will be a non-modifying and
2197 all-compatible solution.
2199 - SEND_MBOX handling has been changed to discard any Content-Length: and
2200 Lines: headers when it rewrites a message by default.
2201 I know that mutt(1) generates them (why, after
2202 http://www.jwz.org/doc/content-length.html?).
2203 Anyway, S-nail does neither use nor manage them, so that any
2204 modification renders those fields invalid, and then it seems best to
2205 discard them anyway.
2206 You may turn the new behaviour off with *keep-content-length*.
2211 The problem was that i really wanted to release on a 25th.
2212 But i have been able to improve S-nail(1) some more, so that this is
2213 possibly the first real release of it. So i'll add only things that
2214 have changed since v13 -- please see below for the complete picture.
2216 - A new CONFIG=CUSTOM make directive was added, and the new user.conf
2217 variables WANT_SCORE and WANT_DOCSTRINGS have been added. It is
2218 possible to create a floating-point free S-nail(1) now.
2221 - If a feature is disabled not even functions stubs should remain now.
2223 - Many places which will work only with local filenames do now actually
2224 check that the target is a local filename.
2226 - Space-separated lists should work again, at a few places at least.
2228 - Tilde commands will be possible, even with -r.
2230 - The *sendmail-progname* has been added after NetBSD 6 dropped the
2231 send-mail entry in mailer.conf(5), which broke S-nail(1). Now users
2234 - When editing messages via ~e or ~v file and pipe addressees will no
2237 - If recipients occur multiple times spread over lists, i.e., To:, Cc:,
2238 Bcc:, then only one occurrence remains, and in the "highest-order"
2241 - The "list" command prints the list alphabetically sorted (somewhat).
2243 - The "help" and "?" commands take an optional argument that shows
2244 a synopsis string for the given command (unless WANT_DOCSTRINGS was
2247 - String allocations are now more efficient. The situation can still be
2248 improved. However, for the first time Berkeley Mail(1) integrates
2249 harmonically into the system allocator, which may madvise(2) unused
2250 memory to the operating system as necessary and/or possible!
2255 Well, a version number 13 is anyway an ugly thing...

2260 FIX MIME quoted-printable encoding (char cast)..
2265 Well, one of the things that have already been started in v13 is
2266 the turn from using "int" when working with 8-bit characters to
2267 "unsigned char" (and as long as we do not support wide
2270 Unfortunately one very important piece of code, that is handling
2271 encoding to quoted-printable, still used integer instead of
2272 unsigned char, which caused an automatic extension cast to take
2273 place, and that resulted in a messed up output.
2279 I want to give prominence to the following people that helped to improve
2280 S-nail(1) during this development cycle, in order of appearance: Martin
2281 Neitzel, Ezequiel Garzón, Björn Persson, Paul Vojta, and, especially,
2282 John Dodson for warm words from beautiful Australia! Many thanks also
2285 After i've officially forked nail(1) aka Heirloom mailx(1) as S-nail(1)
2286 on 2012-09-18 i have been able to work five weeks almost fulltime on
2287 S-nail(1) development. The first three weeks can be characterized as
2288 hectic fireworks here and there, but then it got better and i was able
2289 to work more or less topic-centric. In the meanwhile S-nail(1) is more
2290 than 230 commits away from the Heirloom base--and drifting further apart.
2292 S-nail(1) v13 is the first release of S-nail(1), but it was forked from
2293 Heirloom mailx(1) 12.5 7/5/10 that arose from Berkeley Mail 8. unless
2294 i'm mistaken. What characterizes S-nail(1) v13?
2296 - The build system has been reworked almost completely.
2297 It is possible to fine-tune which features should be present in the
2298 binary and which don't. The name of the binary can be chosen, and
2299 that choice is reflected all through the manual and the template
2300 resource file. The manual is always complete and thus may document
2301 features that are not supported by the actual binary, though.
2302 Please see INSTALL for more.
2304 - Compiler warnings can now be used. Please see the example WARN= flags
2305 in the Makefile, but '-Wall -Wextra -pedantic' should be silent though
2306 certainly insufficient to reflect the complex work of modern compilers.
2308 - The following recipient address list combines some of the major
2309 improvements that have been made:
2311 <addr1@cdröm.de> (bier) , ./file1,
2312 Steffen Smöregäs (Humbabä) <sauer@bäüer.de> (Hummpäa) ,
2313 sabberlot@träbbel.de , (bier2) <a2@bür2.de> ,
2314 a3@b3.de (bier3) , <a4@b4.de> (bier4, und \"bier5\") ,

2316 (co\$mm1) abc1@düf.de (cö,bmm,2) (co\"m\"m.3) ,
2317 co\$bmm1 \"c,ömm2\" co\"m\"m.3 <abc2@däf2.de> , |cat > pipe2 ,
2320 That, on a single line, may be given to ":m" or (quoted) on the
2321 command line, or to "~c" or whatever, and it will work as expected
2322 (well, everything else would be a bug..) and result in the following
2323 sendmail(1) invocation:

2346 So list parsing has been fixed, IDNA support has been added, and it is
2347 possible to mix pipe and file recipients *and* multiple thereof, and
2348 the result is still correct for *all* of them.
2349 I think this kind of list can be given wherever a user can directly
2350 enter such a list. And i think all that is unique to S-nail(1).
2352 - When writing back edited messages the target MBOX mailbox can no
2353 longer become "corrupted" when the trailing newline was removed during
2354 the edit. Also affected FreeBSD and NetBSD mail(1).
2356 - A security fix for CVE-2011-2895 was applied.
2358 - The generated Message-Id: is now more human-friendly.
2360 - The -h command line option has been dropped. Use "-O -h XY" if your
2361 MTA really supports that.
2363 - The -O and -r command line options no longer enforce a one-shot send
2364 mode, and instead persist for the duration of the entire session.
2366 - Variables set via the -S command line option are now (un)set twice;
2367 immediately and after all the resource files have been loaded.
2369 - Other new or changed options/commands, in order of appearance:
2370 recipients-in-cc, smime-sign-include-certs, quote-fold, stealthmua,
2371 add-file-recipients, write, rfc822-no-body-from_, rfc822-show-all,
2372 mail/Mail, idna-disable, idna-strict-checks, ??
2374 - In the codebase itself an effort to reduce duplicate work and
2375 introduce caching, and to minimize the use of local variables, was
2376 started, but that is long term. A lot of improvements here and there,
2377 too, like using the well MD5 optimization from Wei Dai, Chris Torek's
2378 hash algorithm for hash tables etc.
2380 - Incredibly important: an heraldic animal was found: snailmail.jpg!
2382 The full history can be inspected by issuing the git(1) command
2384 $ git log --reverse s-nail..s-nailv13
2386 A new TODO has been introduced, and it is getting longer and longer.
