web2py httpserver log file location

[Yebach]

Hello

I have a strange behavior of my log file, or better to say the location of my log file.

If I understand correctly httpserver.log file is usually located in application folder.

When I have to run the engine the following code is executed

        path = applications/applicationName/engine/e1

        count = 0

        while ( count < 10 and ( os.path.isfile(outPath))):

            count += 1 

            os.remove(outPath)

            time.sleep(0.05)

        

        # Run woshi engine

        path_1 =  os.path.join(path, 'e1')

        os.chdir(path_1)

       

        p = subprocess.Popen(['woshi_engine.exe', scriptId], shell=True, stdout = subprocess.PIPE)

After that the httpserver.log file is created in folder applications/applicationName/engine/e1 and stays there

Now if I run my second application in folder applications (like production version) this file is moved to the engine folder of that applicatio

How can I set the default location of httpserver.log file and that the file is not moved?

Thank you

you can't os.chdir in web2py. first it's not threadsafe. second, you screw up all web2py relative imports.

BTW: httpserver.log is put on the same folder web2py.py is, unless you are using the -f parameter, in which case it sits in that directory, which is the one containing the "applications" folder.

What do u suggest I use to startthe exe program. It takes one parameter (script id)?

for this and the previous issue, you should be on the path "I won't never ever start a process inside a web request".

That being said, subprocess.Popen has cwdir .........

Using cwdir helped to solve the problem with httpserver.log file. Thank you for that

So you suggest using scheduler to start my exe program?

use anything you like EXCEPT something inside the web environment.

Hello

I tried with sheduller 

In model I created a file called scheduler.py

my code 

def runWoshiEngine(scriptId, path, outPath):

    import os, sys

    import subprocess

    count = 0

    while ( count < 10 and ( os.path.isfile(outPath))):

        count += 1 

        os.remove(outPath)

        time.sleep(0.05)

    

    # Run woshi engine

    path_1 =  os.path.join(path, 'e1')

    p = subprocess.Popen(['woshi_engine.exe', scriptId], shell=True, stdout = subprocess.PIPE, cwd=path_1)

    

  

And in my controller function I did the following

 from gluon.scheduler import Scheduler

 scheduler = Scheduler(db, dict(runFunction = runWoshiEngine(scriptId, path, outPath)))

Is this the right approach? and if it is how can I insert records in my db for scheduler tables?

Thank you

[Niphlod]

no, it's not. please read the relevant section on the book to get acquainted with the scheduler.
