tg aa9fa0ebfe add a testcase as documentation (why POSIX isn’t everything); fix comments 2016-07-25 20:36:28 +00:00
tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• 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

tg 816614d3ce re-add realpath to prefer-external-if-argument, needed by Debian 2016-07-24 23:11:51 +00:00
tg e8bbf79d8c invent builtin flags instead of special-casing cat and printf for prefer-external-over-builtin stuff 2016-07-24 23:10:04 +00:00
tg 5401a55a98 optimise away code for a case that’s almost unlikely to happen; fix pasto(?) 2016-07-24 23:07:19 +00:00
tg e0e63c65e6 fix issues with home directory replacement, from Torsten Sillke: 
• if $PWD = ${HOME}foo, no longer show as ~foo in PS1
• simplify ~, ~+, and ~- exactly as $PWD is upon shell entry
  (fixes HOME=/home/./foo but PWD=/home/foo)
 2016-07-24 23:05:52 +00:00
tg 8370c0dd4d experimentally use MKSH_CLRTOEOL_STRING instead of lots of spaces followed 
by lots of backspaces for many clearing scenarios; requested by tmux user
slagtc on IRC

tg 353108cb25 move MIN_{COL,LIN}S here, only user left (edit.c has its own sanity checks) 
and lower them (no need to respect edit.c’s, this is only sanity against OS)

tg a41a62dad7 efficient $(<<<foo) and $(<<EOF … ) implementation, requested by izabera 2016-06-26 00:44:59 +00:00
tg 582e745958 since we already support XSI test -a/-o, they better behave 2016-06-26 00:44:25 +00:00

tg e4f55499c0 hexdump the NUL away 2016-06-26 00:04:30 +00:00
tg df1d7339be I hate our patch(1), it’s not NUL-safe… 2016-06-26 00:00:53 +00:00
tg 262ae5a436 fix most of the ambiguous ${[prefix] var [op [word]]} corner cases 
prodded by izabera and carstenh; resolution is:
• you can’t trim a vector in mksh, still (consider ${@:-1})
• future POSIX will require non-empty “word” for most “op”s
• dissolve in order of standard → extension
• dissolve to prefer “op” over “prefix” where still necessary, mostly

tg 1563b70658 abort read builtin in case of read(2) errors 
noticed by arekm, persuaded by jilles, compared with other equivalent
pieces of code reading in mksh

tg 58f36a9f3a increase default input line, from PLD Linux 
(for as long as we still have the size static, and !MKSH_SMALL)
 2016-06-25 23:49:50 +00:00
tg b5127b03be deprecate *not* using MKSH_CONSERVATIVE_FDS; named fds coming soon 
partially reverts commitid 10048752E6271CABA24 (the manpage, mostly)
and adds a deprecation warning at build time; suggested by izabera

tg 8d811d19d4 typo, found by Joerg Schilling 2016-05-31 19:59:53 +00:00
tg 9ab9ee194c fix shf.c-internal buffer overread on printing digits, 
introduced by the utf_skipcols()-related fixes, more
specifically the check for combining multibyte characters
past end of given width (bogus mixed-up semantics we have here)
by reïntroducing the NUL byte from commitid 1005474EE1E4024A4E4
 2016-05-17 15:36:35 +00:00
tg 55e51d9580 add, with a warning, regression testcases for: 
• trailing combining character
• ${!#} and friends

the warning is: pid_t is signed (so PIDs could be negative) and may be
rather long, in some cases even longer than a C “long”; we’ll need to
handle this by adding checks (sizeof pid_t=gid_t, sizeof pid_t must be
either mksh_ari_t or u_short) and code (always print $$/$! as unsigned,
set unsigned attribute on $BASHPID and friends)
 2016-05-05 22:58:19 +00:00
tg 92833fc6ce fix utf_widthadj/utf_skipcols handling for the remaining cases I can spot 2016-05-05 22:56:15 +00:00
tg 3d130b606a give C_VAR1 precedence over display variable name; izabera pointed out, 
rightfully, that, in POSIX shell, ${!#} is defined, and ${!#123} should work
