car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).
Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.
it was #if solaris'd in R28, and the system I have access
on does declare it now (still Solaris 8)
this can be put back if anyone complains, of course.
it's wrong to use strchr(s, 0) to look for the NUL byte, because in some
environments it apparently might return NULL
use new macro strnul = s+strlen(s) instead (not side-effect safe tho)
convert options() prototype to unsigned (size_t, in fact), and make an
explicitly casted (size_t)-1 the error return code, modelled after what
is often used in Unix libraries
Analysis:
internal_errorf(int, fmt, ...) was only a __dead function if the int argument
was non-0, which the Prevent probably was unable to follow. Change all uses of
internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro-
totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining
uses remove the non-0 int argument; add __dead to internal_errorf() proto;
flesh out guts of internal_errorf() and internal_warningf() into a new local
function for optimisation purposes.
Some whitespace cleanup and dead code removal (return after internal_errorf(1))
XXX u_int32_t is not ISO C99, but seems to work well enough
XXX if it fails anywhere, we'll see in the build logs
XXX apple doesn't have the standard uint32_t and API doesn't specify it
• sys_siglist_defn: rename to sys_siglist_decl as we're really checking
for the declaration in the headers; change wording to “check if … does
not need to be declared” since we don't need to declare if we don't use
• scan for arc4random, arc4random_push, confstr declarations too
• sh.h: confstr declaration is no longer #ifdef __sun__; sort
do not start with a "#!shell" sequence” part of mksh(1) true again; this
was probably lost in mksh R21 or so when I decided/saw that our kernel
always parses shebang lines (code written myself, not taken from pdksh
again or MirBSD kernel, but verified against both)
• bom+shebang execution now works, no need setting EXECSHELL in the test
• bump version
given to execute, standard input (interactive or not), via -c command line
argument, or after “eval”, but not for $(…) comsubs, at the beginning of a
subsequent line, or within a line, etc.); regression test for it
idea during my “week off” (despite the pain), bsiegert@ thinks it's good –
and utf-8 capable tools ought to be able to do this anyway
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version
¹) side effect from creating API-correct cstrchr, cstrstr, etc.
uses goto so it must be better ☻
tested on mirbsd-current via both Makefile and Build.sh
sequence is eaten before the command is called; cought by <TGEN>

fix is to tabcomplete a newline to singlequote+newline+singlequote
* bump version
side (I don't have capacities to scan 71711 files in MirOS for a
standards-compliance whack)
* copyright: mention CVS changelogs as place of contributors' name
and credit information, too
* check.t, sh.h: bump
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more
* 'sigseen' in Build.sh goes away
* Signal name existence is checked in this order:
have our own¹ -> sys_signame[] -> _sys_signame[] -> build our own²
* Signal description existence is checked in this order:
sys_siglist[] -> _sys_siglist[] -> strsignal() -> NULL³
¹ Predefined list of items, for operating systems where we
cannot build² them, i.e. Plan 9 and Minix 3 (e.g. no $CPP -dD)
² The usual cpp(1) stuff
³ Changed later, see below
* Make $CPP test dependent on $NEED_MKSH_SIGNAME (others can
be added here, this is not absolute)
* Make signal name list generation² dependent on $NEED_MKSH_SIGNAME
* Fix check if the generation worked
* Guarantee that sigtraps[*].name and sigtraps[*].mess are valid
C strings; this makes the code shorter *and* removes a few pos-
sible nil pointer dereferences
* Embed autoconf'd usages of sys_sig* / strsignal / mksh_sigpairs
into inittraps()
* Check for each signal 0<=i<=NSIG that
name is not NULL or "" -> replace with ("%d", i)
mess is not NULL or "" -> replace with ("Signal %d", i)
name does not start (case-insensitive) with "SIG" -> name += 3
* In gettrap(), fix check if signal name starts, case-sensitive
or case-insensitive, depending on need, with "SIG" (bug from millert@)
Other changes:
* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now
* Build.sh: use <<-'EOF' consistently
* bump patchlevel to today
