5 2. Notes for S-nail(1) v14.7*
6 3. Current codebase state
11 System specific notes can be found in the next section.
12 Any (optional) feature is adjustable and documented in `conf.rc'.
13 Adjustments may also take place, and are usually done, from the command
14 line, overriding those made in `conf.rc' (if any):
16 $ [make &&] make install
17 $ make uninstall # Won't remove the system wide startup file!
18 $ make distclean # *Completely* cleanup working directory
22 $ make WANT_IMAP=0 install
23 $ make WANT_NCL=0 PREFIX=/some/nasty/prefix install
25 There are also some predefined restricted configuration sets available,
26 which take precedence over anything else:
29 little is left but some air to breathe; no internet connectivity, no
30 internationalized domain names, no IMAP-searches, no regular
31 expression searches, no command line editor, no documentation strings.
34 Like MINIMAL, but with documentation strings, and the regular
35 expression searches as well as the builtin command line editor will be
36 included if that is possible.
39 WANT_SMTP and WANT_SSL settings are enabled, internationalized domain
40 names will be supported if the necessary libraries are available,
41 otherwise identical to MEDIUM.
48 $ make CONFIG=MINIMAL DESTDIR=xtest install
50 would create a `s-nail' binary and install a `s-nail' manual etc.
51 under the prefix `/usr/local' but rooted under [./]`xtest', i.e., the
52 binary would be installed as `[./]xtest/usr/local/bin/s-nail'.
53 The following make(1) target exists, and note that you can use
54 a VERBOSE=1 command line option to gain more (or a different kind of)
57 . all Create / check and update configuration, build.
58 . install Create / check and update configuration, build, install.
59 . clean Remove anything which can be rebuild.
60 . distclean Remove anything which can be rebuild or reconfigured.
61 . uninstall Uninstall (if configured).
63 . config Only create or check and update the configuration.
64 . build Only build (using the existing configuration).
65 . test Run ./cc-test.sh in --check-only mode on the built binary.
67 Only install using the built files of the existing
68 configuration. It is possible to overwrite DESTDIR= when
69 using this target nonetheless (a following `uninstall'
70 won't know about that overwritten value, however).
72 If some libraries are missing that you know are installed on your
73 system, or if other errors occur due to missing files but which you know
74 exist, please ensure that the environment variable `C_INCLUDE_PATH'
75 includes the necessary `include/' paths and the environment variable
76 `LD_LIBRARY_PATH' includes the necessary `lib/'rary paths.
78 The S-nail make system will inspect these two environment variables and
79 *automatically* convert them to cc(1) (c99(1)) -I and -L options (since
80 these environment variables are, different to the command line options,
81 not part of the POSIX standard).
82 To set these environment variables, the following can be done in
83 a Bourne/Korn/POSIX compatible shell:
85 $ C_INCLUDE_PATH="${C_INCLUDE_PATH}:/usr/local/include"
86 $ LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/lib"
87 $ export C_INCLUDE_PATH LD_LIBRARY_PATH
90 The S-nail make system will also automatically integrate pkgsrc(7) paths
91 into this mechanism. pkgsrc(7) is used to handle building (compilation),
92 installation and removal of software packages on a lot of operating
93 systems, including all BSD systems, Linux, Solaris ...
95 2. Notes for S-nail(1) v14.7*
96 -----------------------------
98 S-nail(1) has been or is used regulary on these systems (`uname -srm').
99 Also, i'm (compile) testing manually with WANT_AUTOCC=1, WANT_DEBUG=[01]
100 and WANT_AMALGAMATION=[01] (and WANT_GSSAPI=1), which is what is
101 reflected by the following statements.
103 . All with WANT_AMALGAMATION=1:
104 - Dependent on the configuration you may see some warnings about
105 unused functions. This shouldn't happen for a any of the predefined
106 CONFIG= urations, including the one that results from the default
107 settings of `conf.rc', but it may temporarily happen as long as the
108 codebase is in that heavy fluctuation state. Reports are welcome to
109 vanish them until v20.
111 . All 32-bit systems:
112 - There _may_ be warnings about format strings, like, e.g.,
114 auxlily.c:1610:10: warning: format '%lu' expects type 'long
115 unsigned int', but argument 3 has type 'size_t'
117 This is ugly, but it has been decided to keep the S-nail codebase
118 ISO C89 compatible, so that there is no %z format string modifier.
119 However, `nail.h' tries hard to detect the real type sizes and ends
120 up in a way that should ensure that the actually expected datatype
121 is of the same size in reality -- please see the definition of the
122 `ZFMT' macro in `nail.h' to verify this statement is true.
123 It is also compile-time asserted via __ZFMT_CTA(), in main.c.

208 uses shell functions to ease the task of directory creation etc.
209 (especially useful due to VERBOSE=), and that won't work due to bugs.
210 + You'll see some harmless and ignorable warnings (the problematic
211 looking warning `"openssl.c", line 88: initialization type mismatch'
212 refers to a cast from non-const to const, which shouldn't matter).
214 I'm very interested in reports from other combinations.
215 (It should work practically everywhere, generally speaking.)
217 3. Current codebase state
218 -------------------------
220 Since i've forked Heirloom mailx(1) (for real) as S-nail(1) on
221 2012-09-18 i make my way through the codebase, and i'm getting more
222 and more used to it as time goes by -- of course, i'm thinking object
223 and thus this codebase and i are antipodes.
224 The following modules have not yet been looked at and/or have known
225 design flaws or bugs:
227 IMAP, (IMAP-) Caching
228 GSS-API (Tarqi Kazan reported with LOG that GSS-API still works)
230 I'll hope to be able to release S-nail v20 on 2018-03-25, the 40th
231 anniversary of Mail, as a good one, then. Also see `TODO'.
233 In general, S-nail versions before v14.6.4 should not be used.
234 Furthermore, for now (see below) i mostly care about the core POSIX
235 mailx(1) functionality, everything else has to wait until some later
236 time, mostly because the Berkeley codebase and its nail fork have design
237 flaws in respect to mailbox handling and non-local code jumps (due to
238 / and signals). The (MIME capable) NetBSD and OpenBSD forks have instead
239 addressed this problem, more or less complete, in one or the other way.
241 For S-nail, v15.0 (not before 2016) is dedicated to a Send- and
242 MIME-layer rewrite that will bring the possibility to access each
243 message part individually. Because the Berkeley codebase and its nail
244 fork have design flaws in respect to mailbox handling and non-local code
245 jumps (due to / and signals), whereas the (MIME capable) NetBSD and
246 OpenBSD forks have instead addressed this problem, more or less
247 complete, in one or the other way, v15.0 will also have to address
248 signal handling, because only like that we have the possibility to ever
249 reach a clean state from which we can actually think about re-extending
250 this MUA. It is not unlikely that IMAP support will be dropped
251 temporarily, leaving only the plain mailx(1) plus Maildir, SMTP and POP3
252 functionality. It has to move under the headline reduce to the max.
254 After this massive change S-nail will hopefully see new features on top
255 of a straight, object-based, and thus truly extensible interface.
256 I hope for IMAP, would like to see News, a SQLite-based folder
