This makes ksh 93u+m build on the following system: $ uname -a QNX qnx 6.5.0 2010/07/09-14:44:03EDT x86pc x86 Thanks to polarhome.com for providing the QNX shell account. There are a number of regressions left to work out: arrays.sh[636]: copying a large array fails bracket.sh[129]: /tmp/ksh93.shtests.1753215026.6923/bracket.C/original should be older than /tmp/ksh93.shtests.1753215026.6923/bracket.C/newer bracket.sh[132]: /tmp/ksh93.shtests.1753215026.6923/bracket.C/newer should be newer than /tmp/ksh93.shtests.1753215026.6923/bracket.C/original builtins.sh[683]: real_t1 not found after parent directory renamed in subshell functions.sh[1023]: cannot handle comsub depth > 256 in function io.sh[252]: <# not working for pipes io.sh[337]: read -n3 from pipe not working io.sh[346]: read -n3 from fifo failed -- expected 'a', got 'abc' io.sh[349]: read -n1 from fifo failed -- expected 'b', got 'd' io.sh[379]: should have timed out io.sh[380]: line1 should be 'prompt1: ' io.sh[381]: line2 should be line2 io.sh[382]: line3 should be 'prompt2: ' io.sh[406]: LC_ALL=C read -n2 from pipe 'a bcd' failed -- expected 'a bcd', got 'ab cd' io.sh[406]: LC_ALL=C.UTF-8 read -n2 from pipe 'a bcd' failed -- expected 'a bcd', got 'ab cd' jobs.sh[86]: warning: skipping subshell job control test due to non-compliant 'ps' pty.sh[105]: POSIX sh 026(C): line 120: expected "(Stopped|Suspended)", got EOF pty.sh[128]: POSIX sh 028(C): line 143: expected "(Stopped|Suspended) \(SIGTTIN\)", got EOF pty.sh[151]: POSIX sh 029(C): line 166: expected "(Stopped|Suspended) \(SIGTTOU\)", got EOF signal.sh[310]: kill -TERM $$ failed, required termination by signal 'EXIT' signal.sh[310]: kill -VTALRM $$ failed, required termination by signal 'EXIT' signal.sh[310]: kill -PIPE $$ failed, required termination by signal 'EXIT' (The io.sh failures mean libast sfpkrd() is not working.) src/lib/libast/obsolete/spawn.c: - Removed. Didn't compile due to wrong number of arguments to spawnve(2), but is obsolete and unused. src/lib/libast/comp/localeconv.c: - The initialisation of two static 'struct lconv' variables was done in a way that depended on OS headers declaring the struct members in a certain order. This holds on most systems, but not on QNX, and POSIX does not actually specify the order at all: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/locale.h.html So each member must be initialised by name. But C89 does not support initialising struct members by name, so we have to do it using an initialiser function that simply assigns the values. src/lib/libast/comp/spawnveg.c: - Fix for systems without either P_DETACH or _P_DETACH. src/lib/libast/features/vmalloc, src/lib/libast/vmalloc/vmmopen.c, src/lib/libast/Mamfile: - Add test for sys/shm.h header. If it doesn't exist, as it doesn't on QNX, use the stub vmmapopen() as the real one won't compile. (Mamfile: Add dependency on FEATURE/vmalloc to vmmopen.c.) src/lib/libast/vmalloc/malloc.c: - Remove superfluous externs that are already provided by either AST or system headers. The 'void cfree' extern caused a build failure on QNX because cfree() is of type int on QNX. src/lib/libast/comp/conf.tab: - Remove check for _map_spawnve; src/lib/libast/RELEASE says it was removed.

TODO for AT&T ksh93, 93u+m bugfix branch
|
|
|
|
See the issue tracker:
|
|
https://github.com/ksh93/ksh/issues
|
|
|
|
______
|
|
Fix regression test failures:
|
|
|
|
- There are many regression test failures on NetBSD.
|
|
|
|
______
|
|
Fix currently known bugs affecting shell scripting. These are identified by
|
|
their modernish IDs. For exact details, see code/comments in:
|
|
https://github.com/modernish/modernish/tree/0.16/lib/modernish/cap/
|
|
|
|
- BUG_BRACQUOT: shell quoting within bracket patterns has no effect. This
|
|
bug means the '-' retains it special meaning of 'character range', and an
|
|
initial ! (and, on some shells, ^) retains the meaning of negation, even
|
|
in quoted strings within bracket patterns, including quoted variables.
|
|
|
|
- BUG_CSUBSTDO: If standard output (file descriptor 1) is closed before
|
|
entering a $(command substitution), and any other file descriptors are
|
|
redirected within the command substitution, commands such as 'echo' will
|
|
not work within the command substitution, acting as if standard output is
|
|
still closed.
|
|
|
|
- BUG_IFSGLOBS: In glob pattern matching (as in case or parameter
|
|
substitution with # and %), if IFS starts with ? or * and the "$*"
|
|
parameter expansion inserts any IFS separator characters, those characters
|
|
are erroneously interpreted as wildcards when quoted "$*" is used as the
|
|
glob pattern.
