Hi,community!
I have a question that can be a little offtopic here.
So, sorry if it is.
Situation:
I've got compiled with py2exe wxPython GUI program.
It's ready to deploy on user computer.
What i need:
Some kind of automatic upgrade.
Let's suppose there is a brand new version of app.
Everytime, when the old version starts, it checks local network
and looks for the new version.
If it find something,then automatic upgrade must happens.
And old version replaces herself(or himself?) with the new one.
If someone have this problem in the past, i'd like to hear some hints.
Thanks in advance.

Maybe this gives you an idea:
There are a lot of tracebacks since it's a debug version.
build is a number I use for versions.
TransferProgress is a Progressbar derived class, you don't have to use.
You can replace the call to "gotChunk" with any "write" method of a file like
object.
def fetchUpdate(self,build):
from ftplib import FTP
ftp=FTP('someplace.com')
ftp.login()
try:
fn='ib_%s_%s.zip' % (sys.platform,build)
sz=ftp.size(fn)
if not sz:
raise ValueError,"Zero Size"
_trans=TransferProgress(self,'Download','Downloading %s' % fn, sz,
chunk=8192,in_chunks=True,
writer=open('ibupdate.zip', 'wb').write)
ftp.retrbinary('RETR %s' % fn, _trans.gotChunk)
ftp.close()
_trans.Halt()
file = zipfile.ZipFile('ibupdate.zip')
dir=os.getcwd()
for info in file.infolist():
if info.filename[-1] != '/':
data = file.read(info.filename)
self.create_file(os.path.join(dir, info.filename), data)
return True
except:
traceback.print_exc()
ErrorDlg(self,"Error retrieving latest build")
return False
def create_file(self,pathname, data):
print "Create File",pathname
(head,tail)=os.path.split(pathname)
(name,ext)=string.split(tail,'.')
if ext=='exe' or ext=='dll':
try:
os.remove(head+os.sep+name+'old.'+ext)
except:
traceback.print_exc()
try:
os.rename(pathname,head+os.sep+name+'old.'+ext)
except:
traceback.print_exc()
mkpath(os.path.dirname(pathname))
file = open(pathname, "wb")
file.write(data)
file.close()
