remainging CIDs not listed are either
• false positive (bug in coverity)
• intentional (possibly with lint override coverity doesn't parse)
• VLA (XXX find out how to mix C99 and ANSI VLAs)
• things flagged as possible resource leaks I have no idea about
(no biggie though, and only in error cases I think)
This was actually more evil:
• use a recursive function to display blocks in reverse order,
so that local variable values overwrite global ones
• add array support to typeset -p (from typeset -p -)
• display 'set -A varname' line before setting values, for -p
• if -p got arguments, only display those (from the innermost scope)
Also, the usual amount of code cleanup…
to get rid of the bias introduced by making the hash never zero
… he also pointed out a memory (heap) usage optimisation… which
may impact code size a bit though as I’d need to pass an additional
argument on hashtable function calls… or, forgo the benefit of not
having to pointer-align the key in the structure, which can be as
much as 3/7 octets per item, heap storage… OTOH the saved space is
4/8 octets per not-allocated item, possibly some code (use of an
multiply-add opcode), but the function call overhead/cost would
possibly be quite a bit… I guess I’ll have to measure…
XXX in the future, the entire scheme must be rethinked when we need more
XXX entropy for the hash tables; possibly a cheap add using NZAT and re-
XXX initialise the LCG only on access and when added (so keep NZAT state
XXX separate from LCG state); also, then we will need a more elaborate
XXX scheme, such as adding from environment, editor keypresses and timing
• strlcpy
• utf_wcwidth
note strchr/strstr from misc.c are still #ifdef DEBUG only, as they are
not eligible: they’re for const-cleanliness debugging purposes
XXX get rid of multiple occurrences of binary search code, too…
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
so they’ve got a jump target returning an error at the
end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least
also, optimise control flow and fix more paren matching cases
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all
00:45 -!- variable [root@freebsd/developer/variable] has joined #!/bin/mksh
• +b *!*root@*, +b $a:root, +b $r:root on one more channel
• certain checks to prevent:
00:47 < variable> wjcw: sh.h:308: error: conflicting types for 'getrusage'
01:19 < variable> oh
01:19 < variable> I needed to run Build.sh
deep changes into R40-stable branch
• Version accordingly: HEAD gets 2012/03/24 (hi Eddy/Chris) so we backdate
$KSH_VERSION for R40-stable to 2012/03/20 (hi David) as that comes before
even though it includes today’s latest fixes
• Also, sync clog (including MFC indicators)
if we find any, but not later; do not check on every read
⇒ allows changing COLUMNS and LINES (independent of each other, or both)
for script shells by passing them in an environment setting, even if
we get a tty; interactive shells still check before each line is read…
reported by the PLD guys, thanks
prerequisites are actually fulfilled, i.e. evrn further down than with
the last commit doing this, and move some prerequisites of stuff that
has wandered outside the !INCLUDES_ONLY block with the compile-time
assert changes to the outside, too
fixes FTBFS on MSYS which has neither <stdint.h> nor uint32_t
