Problem with update app

[Scolpy]

I Developed an option for testing an update, if there is a new update, its will be navigated user to download the update.
But I do not know but to download the file check from the server version and then checks to see whether there is a newer version to the app(This problem occurs because of error).

here is my code:

#copyright (c) python-s60.com

Hi yonatan,

Again: try one thing at a time

First, try this example for updating the script, which is very simple and should work easily.

If you did that successfully, try implementing the code for registering the application and writing the settings to a file.

Only after this, you make a simple for checking the version and automatically updating if there is a newer version.

PS: You may also want to check this thread.

Before I put the wrong code.
Now look at the code (to get more information about the error).

By the way, this article explaining how you can update script PY.
But if you already have united all the scripts a SIS file?

But if you already have united all the scripts a SIS file?

Well, if you want to do that with a SIS file you could use the same script changing the extension to .sis

Then, you would install the software as you would do usually when downloading any SIS file from the phone (the browser will give the option to install the software immediatly).

I recommend you to use always the same UID for all versions, so when you install the update, the phone will automaticaly replace the newer version by the old one.

And finally, you could use Ensymble's runinstall option to run the application right after installing.

See the considerations from Ensymble's ReadMe file:

--runinstall
-R

Run the application after installation. After copying all files to the
phone, the application is automatically started.

Note: Phones will ignore this flag in SIS files using self-signed
certificates (see option "--cert" above).

Hope it helps,

Rafael.

I managed to create this code:

import urllib
import appuifw
from appuifw import *
import e32
import os


pathtoapp=os.path.dirname(appuifw.app.full_name())

version=1.0
updatefile= down_update()

timer = e32.Ao_timer()
app_lock = e32.Ao_lock()


def check_update():
url = "http://www.vnixe.net/update/s60_player/lastver.set"  #mention the url
tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"   #where to retrieve
urllib.urlretrieve(url, tempfile)   #retrieve the url



def down_update():
    global version
    if version == 1.0:

appuifw.note(u"You have the latest version of app", "info")

    elif version != 1.0:
#Parameters for accessing the script file on device 
#as well as the path of code on the server
script = "example.py"
server = "http://www.vnixe.net/update/s60_player/"

update = urllib.urlopen(server + script).read()
#Path  of the Python Script file to update 
d = file(u"C:\\system\\data\\vnixe\\update\\" + script, "w")
d.write(update)
d.close()
#The script has been updated successfully
appuifw.note(u"The Script has been successfully updated","info")


def read_version():
    global version   
    CONFIG_FILE='C:\\system\\data\\vnixe\\update\\lastver.set'
    try:
        f=open(CONFIG_FILE,'rt')
        try:
            content = f.read()
            config=eval(content)
            f.close()
            version=config.get('lastver','')
        except:
            appuifw.note(u"Cannot read Last version file", "error")
    except:
        appuifw.note(u"Creating Last version file", "info")
def exit_key_handler():
    write_settings()
    appuifw.app.set_exit()
 
   
def write_version():
    global updatefile
    if updatefile == 1.0:

    CONFIG_DIR='C:\\system\\data\\vnixe\\update'
    CONFIG_FILE=os.path.join(CONFIG_DIR,'lastver.set')
    if not os.path.isdir(CONFIG_DIR):

    config={}
    config['lastver']= version
    f=open(CONFIG_FILE,'wt')
    f.write(repr(config))
    f.close()

    
def quit():
    write_settings()
    appuifw.app.set_exit()


appuifw.app.exit_key_handler = exit_key_handler
appuifw.app.screen='normal'

read_version()

But I can not understand why he does not work (he shows me an error on line 12 19, and I do not understand why it appears at all

Hi yonatas,

You have some indentation problems there ...

def check_update():
url = "http://www.vnixe.net/update/s60_player/lastver.set"  #mention the url
tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"   #where to retrieve
urllib.urlretrieve(url, tempfile)   #retrieve the url



def down_update():
    global version
    if version == 1.0:

appuifw.note(u"You have the latest version of app", "info")

    elif version != 1.0:
#Parameters for accessing the script file on device 
#as well as the path of code on the server
script = "example.py"
server = "http://www.vnixe.net/update/s60_player/"

update = urllib.urlopen(server + script).read()
#Path  of the Python Script file to update 
d = file(u"C:\\system\\data\\vnixe\\update\\" + script, "w")
d.write(update)
d.close()
#The script has been updated successfully
appuifw.note(u"The Script has been successfully updated","info")

This is very wrong

You're puting things outside the functions and if clauses!

Corrected code would be:

def check_update():
    url = "http://www.vnixe.net/update/s60_player/lastver.set"
    #mention the url
    tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"
    #where to retrieve
    urllib.urlretrieve(url, tempfile)   #retrieve the url



def down_update():
    global version
    if version == 1.0:

        appuifw.note(u"You have the latest version of app", "info")

    elif version != 1.0:
        #Parameters for accessing the script file on device 
        #as well as the path of code on the server
        script = "example.py"
        server = "http://www.vnixe.net/update/s60_player/"

        update = urllib.urlopen(server + script).read()
        #Path  of the Python Script file to update 
        d = file(u"C:\\system\\data\\vnixe\\update\\" + script, "w")
        d.write(update)
        d.close()
        #The script has been updated successfully
        appuifw.note(u"The Script has been successfully updated","info")

Don't forget: you have to use spaces for getting your variables/commands inside the functions. If you don't use them your variables will become global and the commands will execute automaticaly when your application starts!


Hope it helps,

Rafael.

Thanks for the fix.


But what can be done to order operations DEF?
In the event, the matter that I want him to perform the following actions:
1) download the latest version from the server.
2) Iamat Is there a new version.
3) if there is a new version, it downloads and installs it from the server, and then write file version (on device), the new version.
4) If you do not, he will release a new message "you have the latest version of the application".

By the way, in global variable "updatefile" I want to be called data from a version (lastver.py), how can i do it

anyway, this is my code:

import urllib
import appuifw
from appuifw import *
import e32
import os


pathtoapp=os.path.dirname(appuifw.app.full_name())

version=1.0
updatefile= down_update()

timer = e32.Ao_timer()
app_lock = e32.Ao_lock()


def check_update():
    url = "http://www.vnixe.net/update/s60_player/lastver.set"
    #mention the url
    tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"
    #where to retrieve
    urllib.urlretrieve(url, tempfile)   #retrieve the url



def down_update():
    global version
    if version == 1.0:

        appuifw.note(u"You have the latest version of app", "info")

    elif version != 1.0:
        #Parameters for accessing the script file on device 
        #as well as the path of code on the server
        script = "example.py"
        server = "http://www.vnixe.net/update/s60_player/"

        update = urllib.urlopen(server + script).read()
        #Path  of the Python Script file to update 
        d = file(u"C:\\system\\data\\vnixe\\update\\" + script, "w")
        d.write(update)
        d.close()
        #The script has been updated successfully
        appuifw.note(u"The Script has been successfully updated","info")


def read_version():
    global version   
    CONFIG_FILE='C:\\system\\data\\vnixe\\update\\lastver.set'
    try:
        f=open(CONFIG_FILE,'rt')
        try:

            config=eval(content)
            f.close()
            version=config.get('lastver','')
        except:

    config={}
    config['lastver']= version
    f=open(CONFIG_FILE,'wt')
    f.write(repr(config))

Hi yonatan,

Well, you created the functions, now just call them!

Try using a menu:

import appuifw

appuifw.app.menu = [(u"Check for update", check_update),
                    (u"Exit", quit)]

And add on check_update function also call down_update after all the code inside that function:

def check_update():
    url = "http://www.vnixe.net/update/s60_player/lastver.set"
    #mention the url
    tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"
    #where to retrieve
    urllib.urlretrieve(url, tempfile)   #retrieve the url
    down_update()

Hope it helps,

Rafael.

Thank you very much for your help, you are very good man.

To the subject - I'm not interested in adding menu, because this file is a separate himself from the menu (see post: http://discussion.forum.nokia.com/fo...28&postcount=7)

You are welcome

I'll always try to help as much as I can

I understand why you don't want the menu, now

In this case you could just call the function when the script starts:

def check_update():
    url = "http://www.vnixe.net/update/s60_player/lastver.set"
    #mention the url
    tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"
    #where to retrieve
    urllib.urlretrieve(url, tempfile)   #retrieve the url
    down_update()

check_update() # This is outside the function, so it will be called when script starts

Best wishes for your new application!

I added the line, but now appears to me an error on line 61.
This is the part where the error (marked red line specific):

Incidentally, I checked that the path that exists.

Hi yonatan,

Again indentation error!

See that I have skipped 4 spaces on the if clause.

I also added a '' on '1.0', I think it's better to work with a string in this case

def write_version():
    global updatefile
    if updatefile == '1.0':
        CONFIG_DIR='C:\\system\\data\\vnixe\\update'
        CONFIG_FILE=os.path.join(CONFIG_DIR,'lastver.set')

    config['lastver']= version
    f=open(CONFIG_FILE,'wt')

Look, now appears to me an error that variable:
"down_update"
No Defined.
It seems to me that because of that Ordinance IF following code (which makes "down_update" to be null).

The incorrect line:

updatefile= down_update()

Hi yonatan,

The line is incorrect because for a variable to be equal a function, this function must return something.

Example:

def test_function():
    my_list = [1, 2, 3, 4]

    return my_list

# Now we can use it:
test = test_function()

Hope it helps,

read_version()

But I still have an error ("down_update()" variable not set).
Tried to reduce the variable "down_update()" Code:

def check_update():
    url = "http://www.vnixe.net/update/s60_player/lastver.set"
    #mention the url
    tempfile = "C:\\system\\data\\vnixe\\update\\lastver.set"
    #where to retrieve
    urllib.urlretrieve(url, tempfile)   #retrieve the url
    down_update()

check_update() # This is outside the function, so it will be called when script starts

But this factor to make only the downloaded file into an (lasnver.set) and continues the whole process.

By the way,
I understand what you wrote in the message earlier that in order that changes will be equal function, the function should return something.
But I do not know what needs to the extent function not showing anything
