[Q] About sessions and Zope
by Max Murdock 25 Feb '99

25 Feb '99

Zope is surely a great system to develop dynamic html sites, and even a novice like me can learn how to use it. My problem is that I've got to be able to make users able to manage sessions in a transparent way: people who get in the site should open a session, create a folder, put there their material and leave to tehe site manager the task to verify what they sent and close the session. And all this should be done seamlessly by the user, possibly with a single form, without having the task to "click to add session", the enter the name, then go to the session and make ti active, create the folder and upload there the files... The main.dtml suggests me to present the user a form with the "manage_addSessionForm" button to press... then he can put the session name and click "add". So he automatically returns to the folder view, and that's not exacltly what "transparent to the user" means, understand me... So I guess I have to reprogram the routine that makes the form: instead of showing the folder it should automatically start the session and ask for a new folder to be created. The PROBLEM: where's that routine? Where's the script that makes the form? Where is it going when I select the "manage_addSessionForm" action? I ain't been able to find it, even with the "find" command, ain't got other ideas... I understand maybe this Q requires a bit of answer... if anyone wont' take this labour I can perfectly understand; otherwise: can someone point me a doc explaining all this? I've downloaded most of the docs in the Zope site, and I can dnload more... TIA! Max Murdock

Re: [Zope] PostgreSQL DA Release Version 0.2
by Oleg Broytmann 25 Feb '99

25 Feb '99

Hi! After adding Database Connection to my folder I found that every time I started Zope the connection opened, so postgres forked. I cannot close the connection - even when I press "Close Database Connection" postmaster stays forked. Only when I shut Zope down postmaster close connection. I am pretty sure it is problem. What if posgres died while Zope is active? Will ZPygresDA restore connection? Who is responsible for the problem - Zope or Adapter? Can I setup a timeout, after which (if there is no activity) Adapter closes connection automatically and restores connection on next access?

Backing up Zope's database?
by Martijn Faassen 25 Feb '99

25 Feb '99

Hi there, We're running Zope on an NT server here and the backup system (Arcserve) apparently gives an error when it tries to backup Zope's 'var' directory. I would like to have this succeed (and end up with a non corrupted database, of course :), so here are some questions: * is this perhaps fixed by Zope 1.10? I read something about Zope 1.9 not doing proper file locking on NT yet, so there is some difference here. * Is copying a database while Zope is running a good strategy? (probably not) * What other options are there? For instance, NT seems to be able to copy the var dir just fine, so perhaps a copy could be made that Arcserve could backup. Still, that database would be backuped while Zope is running, so perhaps this isn't a good idea. Thanks in advance, Martijn

Bug with DateTime.float method ?
by chalaouxf＠synbio.tpgnet.net 25 Feb '99

I GOZ, I have a problem with the float method from DateTime module !! It seems that Linux and WIN32 platform(NT) do not give the same result. Is there an explanation? NT (Zope 1.1.02) ----------------------- >>> z=DateTime.DateTime('1999/02/25 0:00pm US/EASTERN') >>> z DateTime('1999/02/25 12:00:00 US/Eastern') >>> float(z) 919962000.0 LINUX (Zope 1.9) ------------------------ >>> z=DateTime.DateTime('1999/02/25 0:00pm US/EASTERN') >>> z DateTime('1999/02/25 12:00:00 US/Eastern') >>> float(z) 35849.7083333 FR.

RE: [Zope] Preserving Settings during a user's session
by Jeff Nielsen 25 Feb '99

25 Feb '99

Wow! Thanks for all the replies to my query about preserving session variables. I rather like Christopher's idea about using a single SessionID variable. Most of the data in my application is in a database (SQL Server) and I could create a Session table with a sequential ID that would hold the values I want. I think I'll stick with the simple method, using the format www.server.com/zope/page_name?SessionID=1234. I'm still rather a Zope novice and my immediate priority is to get my web site up and running instead of becoming a Zope master... I'm using Zope with IIS and it does provide session tracking with a unique ID, but it requires the use of short-term cookies. I could pass the session ID from IIS to Zope (I think), but that violates my no-cookie goal. Similar to what someone mentioned somewhere in the thread, my goal is to keep the client side as simple as possible in order to minimize end-user issues. I prefer to do all the complicated processing on the server, which is completely under my control... Again, thanks for all the response. Jeff jeffniel(a)ix.netcom.com

Proposal: Public read access to Zope CVS
by Ken Manheimer 25 Feb '99

25 Feb '99

I've put together a proposal for an arrangement that would make the digicool CVS repositories (and other peoples Zope-related repositories, if they care to participate) available for read across the internet. Please take a look at it, let me know if you have any suggestions, concerns, interest in participating, etc. Ken Manheimer klm(a)digicool.com

count- of-by-one?
by ron＠rotflol.cx 24 Feb '99

24 Feb '99

count- (statistic-name) seems to be of-by-one. [select_systems is a ZSQL Method]    This should return 41 [counting the rows displayed when a normal report is displayed]. It however returns 40. BTW, is this the most efficient way to get the number of rows returned by a query? -- <- Ronald Offerman | ron(a)offerman.cx <- Root Powered Carrot Munchers Ltd. Inc. SA AG BV "This is Linux Country.

RE: [Zope] Adding users in External method
by Theodore Patrick 24 Feb '99

24 Feb '99

There is a default object in any user_folder called manage_users It handles managing users in the user folders. If you have manager privileges as a user, submitting the following form in the user folder will add a user to the folder. You could process these in DTML to remove the security. If using dtml, Be careful this is a security hole if allow the users to be set as manager!!!  <FORM ACTION="acl_users/manage_users" METHOD="POST"> name<INPUT TYPE="TEXT" NAME="name" SIZE="20"><BR><BR> password<INPUT TYPE="PASSWORD" NAME="password" SIZE="40"><BR><BR> password2<INPUT TYPE="PASSWORD" NAME="confirm" SIZE="40"><BR><BR> domains<INPUT TYPE="TEXT" NAME="domains:tokens" VALUE="" SIZE="40"><BR><BR> Roles<SELECT NAME="roles:list" SIZE="5" MULTIPLE><OPTION VALUE="User">User</SELECT><BR><BR> <INPUT TYPE="SUBMIT" NAME="submit" VALUE="Add"> If you had the users info as variables you could set them = to the name values of the fields above in dtml: <newuserfolder>.acl_users.manage_users.name = namevalue ect... ect... ect... The syntax above is incorrect but I think you get the point. Just convert the form to dtml. Hope that helps. ----Original Message----- From: Shaw, Howard [mailto:ShawH@sths.org] Sent: Wednesday, February 24, 1999 4:13 PM To: 'Zope(a)zope.org' Subject: [Zope] Adding users in External method Ok, guys, you stumped me. Why are all the functions for adding Users to UserFolders mangled? Do I really have to create a REQUEST object to add users using an Extension class? I've got the code creating a directory, a UserFolder in it, but how do I add the user? If I need to create the REQUEST and pass it to manage_users and let it toss it around internally, then could someone please show me how to compose a REQUEST from within an External Method?

FYI: Zope Roadmap online
by Paul Everitt 24 Feb '99

24 Feb '99

I just posted a News blurb on the site saying I've put the Zope Roadmap online: http://www.zope.org/Information/Roadmap This was an email I sent out on January 18th that tried to sketch out what we'd do over the ensuing two months. Fortunately I wrote the email in Structured Text :^) Anyway, looking back over it today, I'm pretty shocked to see that we are actually ahead of schedule. By the end of this month we will have finished or released the beginnings of 13 of the 21 things discussed. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

Maybe we're crossing wires, but I think we're talking about the same thing here... basically your "ticket" is my "sessionID" we then get into the discussion of whether or not this information is persistent across time (and if so, how much). Obviously this information must be persistant across SOME value of time for it to be of any value. The question for me is whether or not this piece of information should bring with ti OTHER information referenced with the sessionID as an index. Hmm, how to explain this :-) > > Whether it's persistent or not is a different question, > > but that seems to be the only different in my view. > > By persistent, you are referring to the session state > or the session id? They are implicitely the same... a "session state" is just an object associated with a specific session ID. > [ stuff about firewalls/proxies ] > Now this is just handwaving at this point, but XML-RPC is just a new mime-type, nothing more. So as long as your firewall doesn't filter based on mime-type, or allows you to determine which ones... you should be OK. This would be no different than filtering based on image/gif, or something along that lines.

I agree, but for the foreseeble future, my crystal ball says HTTP/HTML will continue to dominate the client/server level... what is more interesting from a Zope perspective is teh server/server middle tier, which will probably move toward a combination of CORBA and XML.
