Hmm, this looks like it has to do with the runtime environment. As external
executables are not found, PATH seems to be incorrect.

Can you try to call them with absolute pathnames? Like

   (pre? "{"   # make sure jwt3 returned json and not an error
  (in (list "/path/to/jwt3" (pack "--key=" Key) ...

If this works, start httpGate not just with 'su' but 'su -' to get the
right env.

Strange behavior with 'httpGate'

[Erik Gustafson]

Hi List,

I have a PL app running on a DigitalOcean droplet, behind httpGate.

The relevant entry in my 'names' file is:

   api  erik /home/erik/picoLisp loves-wake-log ./pil
loves-wake-2.0/server/main.l -main -go -wait

For this project I've been experimenting with JSON Web tokens, using my
naive 'picolisp-jwt' library (https://github.com/erdg/
picolisp-jwt/blob/master/jwt.l). It's a simple wrapper around 'jwt3', a
command line utility for encoding/decoding JWTs that ships with ubuntu
16.04.

The function 'encodeJWT' works great. But the strange behavior is that
'decodeJWT' only works under very particular conditions.

If I ssh into the server and restart 'httpGate' (and stay logged in on the
remote server) everything works as expected. But as soon as I close the ssh
session, the 'decodeJWT' function breaks - even though httpGate continues
to function as expected. Everything else works, just not 'decodeJWT'.

If I log back into the server and start the app from the command line
(using the exact command from the 'names' file, executed from the same
directory), then 'decodeJWT' works again. And that's without touching the
already running 'httpGate'. But as soon as I logout, the function breaks
again.

But regardless of whether I started the server process, or httpGate did,
'decodeJWT' receives the same arguments (according to the log file).

I thought it might be something with 'jwt3', so as an experiment, I decided
to substitute the call to 'jwt3' in 'encodeJWT'/'decodeJWT' for a different
command line utility - 'pyjwt'. When I restarted httpGate, or "manually"
started the picolisp server process, everything worked. But as soon as I
logged out and let httpGate take over, both encode/decode functions were
broken.

And now my log file was littered with 'pyjwt: can't exec' - which I believe
is the same error message that 'call' will throw if it doesn't know what to
do with its arguments? It seems that calling external programs isn't
working when the process is started by httpGate.

So to summarize:

Everything works so long as I'm logged into the server and have restarted
httpGate or started the picolisp process manually (same as httpGate does).

Calling external functions is broken, once I've logged out and left
httpGate running in the background. But everything else (that doesn't call
an external program via 'in') continues to function as expected.

Any ideas as to why this might be? This one has really thrown me for a loop!

httpGate was started with 'sudo'...

I'm using a local install of picolisp 15.11 (because some of the code in
the project uses the old style namespace calls, and also because 15.11 is
the default global install in ubuntu 16.04)

Thanks,
Erik

This is another issue. As I said, there is no /bin/ in Android,
so Termux comes with /data/data/com.termux/files/usr/bin/bash
and scripts must call this instead of #!/bin/bash.

But here we are concerned about PilBox which has nothing to do

This code is problematic.

   Runtime.getRuntime().exec("/system/bin/chmod 777 " + filePath);

is not a good idea. I would not rely on the 'chmod' command being available
(i.e. busybox access). Perhaps this even gives the "no such file" ;)
There is setExecutable(true) in Java for that.

I tried some variations. 'chmod' on bin/picolisp to non-executable, or replacing
it with some other (non-ELF) file, gives different errors.

Only if I really do 'rm bin/picolisp' I get that error.

Yes. The Android way, by calling 'getFilesDir().getPath();'. This gives the

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.

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!

Hi Arie,

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
