It was unreasonably hard to debug problems with iffe tests that
fail to compile where they should (particularly output{ ... }end
blocks that write esserntial headers).
In e72543a9 the problem was already somewhat mitigated by making
some of the failing output{ ... }end blocks emit #error directives
so that invalid/incomplete headers would cause an error at a
sensible point, and not a much harder to track error later.
This commit further mitigates the problem by making the Mamfiles
respect an IFFEFLAGS environmenet variable that is prefixed to
every iffe command's arguments. The typical use would be to export
IFFEFLAGS=-d1 to enable debug level 1: show compiler output for all
iffe tests. This now makes it reasonably feasible to detect
problems in the feature tests themselves.
src/**/Mamfile:
- Import IFFEFLAGS environment variable using setv.
- Prefix ${IFFEFLAGS} to every iffe command.
src/**/features/*:
- Amend the new fail error messages to recommend exporting
IFFEFLAGS=-d1 to show the cause of the failure.

Fix regression test failures:
|
|
|
|
- There are many regression test failures on NetBSD.

|
|
|
______
|
|
Fix build system:
|
|
|
|
- ksh does not currently build on AIX or QNX.

______
|
|
Fix currently known bugs affecting shell scripting. These are identified by
|
|
their modernish IDs. For exact details, see code/comments in:

|
|
- 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.
