Maybe it has something to do with apt-get upgrade as well?
Glad to hear the issue disappeared!

You don't even need a DB to test the locking, the 'ctl' function will do.

To test it, open two terminals and start pil in both of them. Then in the first
one:

   : (ctl "a" (key))

This creates a file "a", locks it, and waits for you to type a key.

Then in the second terminal:

   : (ctl "a")

This should block, because the first one has still a lock on the file.

Now, if you type any key in the first terminal, both 'ctl' calls should return.

Arie, I followed your WSL steps on a newer machine and I don't see the db
locking issue any more. Thanks! My other machine has the problem but its
WSL is at least 6 months old - so maybe it was fixed in WSL since then or
possibly something fixed/changed by following your instructions. Thanks,
I'll do some additional testing later

Re: Question about tutorial ...

Hi Alex,

1) root mode was because I tried a lot of different things, but missed the
obvious family64.tgz 
2) had a few problems with cd-ing into folders, because under Windows it is
a bit different

So, after unpacking family64.tgz into a local folder in my home dir
everything works great!

Now starting to really learn the PicoLisp language better.

@Joe could you show me an example where db locking didn't work?
 Maybe I can test this and see if it does work correctly in the way I
now set up PicoLisp in WSL?

Thx. again!

This is probably because the "family/" directory does not exist yet. Or did you
unpack the file "family64.tgz"?

In general, I would recommend not to run all this as user root. Better log in as
a normal user, and do in any of your local directories:

   $ tar xvfz /usr/share/doc/picolisp/doc/family64.tgz
   family.l
   family/
   family/@
   family/B
   family/C
   family/A
   $ pil /usr/share/doc/picolisp/doc/family.l -main -go +

Question about tutorial ...

[Arie van Wingerden]

Hi,

tried this:

*​ root@HP-Arie:/usr/share/doc/picolisp/doc#  *​
*pil @lib/http.l --server 8080 @doc/hello.l -wait*
works OK! Can use the GUI from within standard Windows in browser.

But this:
*   root@HP-Arie:/usr/share/doc/picolisp/doc# **pil family.l -main -go +*
fails with:


*!? (pool "family/" *Dbs)   "family/" -- Open error: No such file or
directory   ?*

I guess it has something to do with location of
​some ​
PicoLisp files?
​What am I doing wrong?


TIA
