Subject: PATCH: More comments in ztst files
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

General remark -- in several of the ztst files, there are comments about
not being able to test various interactive operations, such as `select'
loops (always read from terminal) or `[[ -t 0 ]]'.  We should lump these
into a later test and use the zpty module the way we do for completion.
I haven't actually done this.

In 04redirect.ztst:

# Following two tests have to be separated since in
#   print bar >foo >bar && print "$(<foo) $(<bar)"
# the multios aren't flushed until after the substitutions take
# place.  This can't be right.

Multios are of course handled by forking a process that, in effect, performs
"tee" from the output of the command to the multiple output descriptors.  To
fix the abovementioned bug, we'd have to synchronize the start of the next
command with the end of the "tee" process.

# Currently, <out{1,2} doesn't work: this is a bug.

Hmm, seems to work for me.  Anybody know when it began to, or why whoever
wrote this comment thinks it doesn't?  (No change for this in the patch.)

In 10prompt.ztst:

# 'mydir=$PWD; hash -d mydir; print -P %~' doesn't seem to abbreviate
# to ~mydir in a non-interactive shell.  Is this correct?

This apparently is correct.  From utils.c:adduserdir():

    /* We don't maintain a hash table in non-interactive shells. */
    if (!interact)
	return;

However, `hash -d mydir=$mydir' bypasses adduserdir() and adds the entry,
so the comment in utils.c is not quite accurate either.

In 13 parameter.ztst:

  # WHY DO I NEED TO QUOTE ${array} HERE?????
  print IF{"${array}",THEN}ELSE

Because without the quotes it expands to (IF{once) (bitten) (twice) etc.,
whereas with the quotes (IF{once bitten twice shy,THEN}ELSE).

  # it doesn't *say* these are case-insensitive without i...
  # I think this is a bug.

Where "these" are ${(o)...} and ${(O)...}.  The manual does in fact say
that (i) means sort case-insensitively with (o).  By implication, sorting
should be case-sensitive without it, right?  The results seem to be in
case-sensitive order, so I'm not sure what was up with this comment.

Peter must have really been pining for William Dalrymple at this point.

  # ${bar} -> $bar  turns this into $$, which doesn't strike me as correct.

Where "this" is ${(...)${bar}}.  We've long since decided that's correct;
in fact, zsh now prints "bad substitution" for ${$bar}.

That's it.  The other two hunks remove a comment from 01grammar that I
meant to remove in my last patch for it, and add to ztst.zsh a line to
print when the tests begin as well as when they end, which is helpful to
my sanity.
