• ensure that bool/true/false are cpp macros, overriding any pre-defined
• document the requirement that tobool(x) must map any-type 'x' into bool
• document the requirement that a bool must only be true or false, and
that it (tobool() rather) must have an identity mapping to 'short'
• possibly fix ksh_func for/and fpFUNCTf – maybe spotted by cnuke@
a bit more with POSIX and the other shells
I considered http://austingroupbugs.net/view.php?id=253 but the use
of bi_errorf() is interesting, especially as it’s often enough a
noreturn function, and funnily enough, 'cd -P /foo' returns 0 while
'chdir -P /foo' fails (so idk where to put -e)…
⇒ consider merging simplify_path()
• move funcs.c:c_cd() to misc.c
• make misc.c:make_path() static, c_cd() is its only user
⇒ mark as obsolete
• tweak misc.c:set_current_wd() to drop ksh_get_wd() argument
should be no code change, but the entire path stuff is a mess…
so expect actual implementation changes or even rewrites shortly
and switches to the TARGET_OS=Linux
• introduce android as regression test suite category
• add an android specific standard alias
• clean up redundant ‘-o sh’ arg in a few checks
UTF-8 BOM instead (UTFMODE has a separate value now for activated
during BOM skipping)
• parsing a COMSUB now skips UTF-8 BOM, too, but only temporarily
(token stream, lexer output / parser input), EOS terminated, let
SASPAREN use the same lexing as SBASE (e.g. COMSUB recursively)
• make wdstrip recursive
• fix processing of COMSUB in wdstrip
⇒ pass comsub-1 test
• expose another debugging function
• use shf_putc (macro), shf_putchar (function) ipv tputc
• replace shf_putchar(x,y) calls for side-effect-less x with shf_putc
• plug another bug in the tree code – '\' → "\\" (backslashes must be
escaped inside double quotes, too)
• adjust testsuite (and, I _had_ wondered…)
EOF) # works again now, plugging a regression
• rewrite the here document parsing code to be *much* more efficient
(and a bit more readable too!) using goto, while here (no kidding)
① currently: ((cond) ? true : false) but (!!(cond)) and casting to bool,
the latter only if stdbool.h, would also work – which performs best on
(and across) all supported systems?
instead, but the parser for the so-called “backticks” (U+0060) still emits
plaintext COMSUB wdstrings, and the evaluation code emits plaintext if the
code is not run (‘-n’ option), so it’s not worth the effort and memory ma-
nagement issues, even though it _would_ optimise the most common case…
Bump version numbers, sync regression tests; add one testcase from the old
webpages too. Sync manpage, this now works, but keep the workaround in, as
“portability issue” with slightly changed wording.
Also, /bin/sleep must be used in one manpage example if sleep is built in.
• functions called by mksh’s grouping memory allocator
• functions called by mksh code itself
the latter may be changed to call the internal grouping allocator,
if a porter so desires (but if this were recommended, the code in
question would already do so, so…)
• PIPESTATUS now supported (like bash 2) whose last member
may actually differ from $? since the latter may not be the
result of a pipeline partial command
• add regression tests, documentation, etc.
• in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment
variables if setlocale/nl_langinfo(CODESET) doesn’t suffice
• add the ability to call any builtin (some don't make sense or wouldn't
work) directly by analysing argv[0]
• for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment
variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set
• when called as builtin, echo behaves POSIXish
• add domainname as alias for true on MirBSD only, to be able to link it
• sync mksh Makefiles with Build.sh output
• adjust manpage wrt release plans
• link some things to mksh now that we have callable builtins:
bin/echo bin/kill bin/pwd bin/sleep (exact matches)
bin/test bin/[ (were scripts before)
bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now)
• drop linked utilities and, except for echo and kill, their manpages
• adjust instbin and link a few more there as well
a mirtoconf check, would’ve been a real problem on an LP64 platform
• sh.h: work around a bad interaction between -Wformat on gcc and manual
string pooling for T_synerr, which is used in place of a format string
in some places
– possible integer overflows in memory allocation, mostly
‣ multiplication: all are checked now
‣ addition: reviewed them, most were “proven” or guessed to be
“almost” impossible to run over (e.g. when we have a string
whose length is taken it is assumed that the length will be
more than only a few bytes below SIZE_MAX, since code and
stack have to fit); some are checked now (e.g. when one of
the summands is an off_t); most of the unchecked ones are
annotated now
⇒ cost (MirBSD/i386 static): +76 .text
⇒ cost (Debian sid/i386): +779 .text -4 .data
– on Linux targets, setuid() setresuid() setresgid() can fail
with EAGAIN; check for that and, if so, warn once and retry
infinitely (other targets to be added later once we know that
they are “insane”)
⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again
a string buffer whose window size is currently 32 (initial), your data
is 96 bytes, this routine used to resize the buffer to 64, append your
first 64 bytes to it (no matter if there's already something in it)
and then writes the remaining bytes to stdio fd instead of the string…
if it doesn’t SIGABRT before
discovered by wbx@ – thanks – bug inherited from pdksh 5.2.14 (AD 1999)
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
floating point support always in the process, as shf doesn’t support it
⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
[trunk revision 162057] (Debian 20100711-1) except:
– a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
taking an enum instead of an int because they’re too stupid to adhere
to POSIX interfaces they design by themselves
– all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more
• avoid calling realloc twice in sequence, since the final
size is known at the first call already
• do not lstat(2) the same path twice in the Hurd codepath
concurrently accessing the same $HISTFILE be more synchronised with
each other: empty lines (just pressing Return) and duplicates (that
are split and written twice by the lines loaded from $HISTFILE in
the meantime); requested by Maximilian “mxey” Gaß in #!/bin/mksh
some idiotic terminal emulators and/or people seem to use the es-
cape codes normally denoting Alt-Arrowkey instead so let's simply
bind them to the vt_hack as well... (untested)
• merge the rest of branch tg-wcswidth-behaviour
• enhance test cases for wcswidth-like behaviour
• switch hash table collision resolution algorithm to Python’s as announced
• bump vsn
│remember to restore errno (ie. stop someone from making a mistake later)
│ok guenther
check.t, sh.h: bump vsn
I wonder though why errno must be restored even if nothing was
called after reading it… moid?
