• make fast character classes even faster by removing the C_SUBOP2 hack
in favour of a separate seldom-used ksh_issubop2 macro (which also
makes ctype() side-effect-safe) which is a slower class (no change there)
• optimise cases of ksh_isalphx followed by a ksh_isalnux loop
(used parsing variable names)
• remove a misleading comment in initctypes() about \0 from pdksh
• rename C_ALPHA to C_ALPHX to make it more clear the underscore is included
• sprinkle a few ord() in there
• add new ksh_isalpha() which tests for [A-Za-z] (slow character class)
• there is no '_:\' drive on OS/2 (which inspired the whole changeset)
install both lksh and mksh manpages from Build.sh (Martijn Dekker)
spelling fixes (Larry Hynes)
manpage improvements (Martijn Dekker)
initial port to Harvey-OS’ APEX (Ronald G. Minnich, Elbing Miss, Álvaro Jurado)
more from komh’s OS/2 port (KO Myung-Hun)
• track $TERM for the types tmux uses /^screen(-.*)?$/
• when tmux is in use (or GNU screen, really), use the, now
hardcoded, clear-to-EOL string; otherwise, use the old behaviour
• drop unnecessary x_e_rebuildline()
carefully tested to behave no worse than R52b
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used
Closes: LP#1580348
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
‣ used in some places
• (c - '0') → ksh_numdig(c) # may take *x++ argument
• (c - 'A') → ksh_numuc(c) # may NOT take *x+= argument
‣ idem for ksh_numlc(c) and 'a'
‣ these need changing for EBCDIC
‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already
getn() parses a decimal 32-bit integer, getint() a POSIX- or ksh-style based
integer with unsigned wraparound to 32 bit, then possible negation (so that,
for example, -0xFFFFFFFF continues to work)
handle unknown bases as ksh93 does: larger downgrade to 10
(although our max will stay 36, as ksh93 doesn’t have upper/lowecase)
and smaller downgrade for typeset -i, but not for arithmetics
• all: bump version to R50-current; add more comments; whitespace
• all: remove all mkssert(); we’ll do full re-runs of scan-build and,
hopefully, Coverity Scan/Prevent
• check.t: fix a testcase (sed could exit false, but we don’t care)
• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *
use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)
‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
‣ always use our wcwidth code
‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1
• make parsing numbers with leading digit-zero as octal independent of
mksh/lksh and dependent on set -o posix; adjust manpages to match
• warn about these changes and why mksh uses 32-bit consistent arithmetics
and point people to lksh for host-long undefined-behaviour arithmetics
• point out, explicitly, that it is *legal* for the operating environment
to make 'print $((2147483647 + 1))' (on a 32-bit system; adjust for a
64-bit system) to run 'rm -rf ~ /' instead
to $SECONDS (tbh, in 2038 we’ll have more problems than just that,
which is why 64-bit arithmetics, or unlimited-precision ones, are
on the “plans” list)
is larger than the positive range of the latter (implementation-defined), so
avoid them in all explicit cases and rearrange stuff and check for it
(I’m gonna have to revise lots more code…)
• tty_fd is now never closed
• new tty_hasstate tracks tty_state (cf. thread around
http://article.gmane.org/gmane.os.miros.mksh/79 and PLD bug)
• as users requested, importing COLUMNS or LINES from the environment
now removes its special-ness as does unsetting it
• otherwise, setting COLUMNS or LINES is honoured until the next SIGWINCH
arrives or change_winsz is otherwise run (e.g. before displaying the
prompt in the interactive command line editing modes)
• SIGWINCH is now honoured before each reading of $COLUMNS and $LINES too
• change the Uhr to match – it no longer calls stty(1) ☺
