After further examining the iffe code I found that fail{ ... }end
as well as pass{ ... }end blocks are executed in iffe's current
environment, using a simple 'eval', with no safeguards whatsoever!
This does of course afford maximum flexibility... for example, a
block can 'exit 1' to abort the iffe run and the whole build with
it. We can use this to abort properly on fatal compilation errors.
src/cmd/INIT/iffe.sh:
- Complete the fail{ and pass{ documentation; it should really be
known that they run in iffe's current environment.
- Make one change: for just the 'eval' command that runs these
blocks, redirect standard error back to the saved $stderr file
descriptor so these blocks can write error messages using the
standard >&2 instead of the undocumented >&$stderr.
src/lib/**/features/*:
- Write error message to standard error and error out properly when
an output{ ... }end block fails to compile, instead of writing an
#error directive to error out later.
