Extraneous symbols in Calendar day reminder form, STREAM-NOT-OPEN error when aborting form

[pamoroso]

Describe the bug
When adding a day reminder in the Calendar LispUsers program, every character in the text of the form is followed by a black rectangle symbol. Aborting the form makes the program crash with the error STREAM-NOT-OPEN.

To Reproduce
Steps to reproduce the behavior:

1. sign into your Interlisp Online account
2. under Initial Exec, select Interlisp
3. click Run Medley
4. at the Exec, evaluate (FILESLOAD CALENDAR)
5. at the Exec, evaluate (CALENDAR)
6. at the prompt Please enter a default host & directory for reminder files:, press ENTER
7. click a year
8. click a month
9. click a day
10. click Add
11. click Abort

After step 9 the extraneous symbols show up in the the day reminder form as in the first screenshot. After step 10 the program crashes and a STREAM-NOT-OPEN backtrace window opens as in the second screenshot.

Expected behavior
No extraneous symbols in the day reminder form. The form is dismissed with no errors when clicking Abort.

my guess without looking is that one problem is Y2K: software not expecting 4 digit years and doing
interlisp "subatom" trying to pick off the hour and minute. My guess is that the 'fix' might be to switch to using CL:GET-DECODED-TIME.

The black characters could be an external-format issue but that's less clear. The error is around a closed "basebytes" stream... where do those come from?

I think I'll take back the "good first issue" maybe a good second or third.

This looks like another problem introduced somewhere leading up to Medley 3.5.  I just tried your example in a Medley 1.0 sysout and it works fine there.  Clicking Abort does not cause a break.  It looks like in your example the program is printing the correct data but it's also putting an extraneous black box before every character. Why that should be I have no idea.             - Michele

Try in loadups/lisp.sysout??There should be a url to fetch it using chat(shell) and curl--LarryMasinter.netOn Apr 16, 2023, at 9:06 AM, Michele31415 ***@***.***> wrote:ad:

It seems to be an EXTERNALFORMAT / TEDIT version issue. That's a fat string being displayed as bytes in the day window. The black blobs are 0 bytes. You can reproduce the black blob issue trivially with:

(TEDIT (OPENTEXTSTREAM (OPENSTRINGSTREAM "BLOB")))

in a system built without the new TEDIT.

OPENSTRINGSTREAM produces a stream with external format STRING, OPENTEXTSTREAM produces a stream with format TEDIT, and that doesn't get read properly by the old TEDIT. If you use Ron's rmk78... newer TEDIT branch it fails in other more mysterious ways, but not for the black blobs.

We discussed a similar TEdit issue in issue #1109 motivated by this thread.
