Zope for Client / Server Game advice seeked
by David Stidolph 30 Jun '00

30 Jun '00

I'm working on a Client / Server game. My plan is to write the Game code on the server (and some on the client) in Python and use Zope as the persistent database solution and interface to the server. The game objects will probably be based on C++ objects and I was considering using SOAP as the transport for all non-high traffic messages between the server and the client (high volume messages will probably have to go UDP). For UI I was thinking of DHTML with a Windows application using IE 5.5 embedded in it. This is a high level look at what I was considering and I am looking for advice and opinions - especially in regards to Zope or other alternatives. I know the magnatude of the project - I do have some others to help, but I am the only one with actual game development experience. The game code WILL be Open Source and is primarily to teach myself and others some new technology with a intereasting purpose. Thanks in advance, David Stidolph (or email dstidolph(a)mshow.com for work email)

Hi, I working on an structure like this: folder1 | folder11 | folder111 I have some objects in folder111 which I want to pass as parameters to a dtml method in folder1 (two levels above). I tried something like: <dtml-with "PARENTS[2]"> <td><dtml-var "mtdCreate(_.None, _, qry_item='par1',qry_table='par2', list_name='par3')"> </td></tr> </dtml-with> where par1 and par2 are strings and par3 is an object in folder111. mtdCreate is in folder1. it doesn't work... How can I do that ------------------------------------------- E-mail enviado pelo servidor do CEFETCampos

RE: [Zope] Version Lock Error

When the users hit a DTML method that tries (maybe in a roundabout way, have a ZCatalog?) to write to an object in the ZODB that's been locked in a version, you'll get this. Try to figure out where it's happening by examining the DTML method that they're hitting and figure out where you're trying to do writes. > -----Original Message----- > From: ksmith(a)web-oats.com [mailto:ksmith@web-oats.com] > Sent: Thursday, June 29, 2000 6:04 PM > To: zope(a)zope.org > Subject: [Zope] Version Lock Error > > > Hello, > > For some reason anonymous users are getting locked out > of the site when I try to use versioning. > > It doesn't happen right away, only after I've made a > few changes. > > Does anyone have any ideas on what's happening?? > > Thanks in advance. > > Kevin Smith > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

This would be consistent with "atomic updates." What it means is that a transaction is not written to the Data.fs file until it has completed, and when it is finally written out, it's done as an atomic operation, i.e. at the system level it is a single write operation and nothing else happens on the system until it completes. >From that you can infer that if you were reading the Data.fs file (making your backup copy) at the same time, it would be impossible to read the file "in the middle of an update." If both read and write requests hit Data.fs at essentially the same time, one goes first and the other waits until the first completes. So if the write gets first shot, the read will block until the write (meaning a completed transaction/update) finishes, and your read will include that last update. If your read gets first shot, then it will not include the update. You will under no circumstances get *half* an update. One of the other things that makes this possible is ZODB being of a "journaling" nature. i.e., all updates are *appended* to Data.fs. This is why you must periodically pack the database, which conglomerates all the updates back into the base datastore (or whatever those wacky Zopistas call it. ;) that comprises the first part of the Data.fs file. I think that's all correct. Someone please throttle me senseless if not. :-) -cw-

Hello, For some reason anonymous users are getting locked out of the site when I try to use versioning. It doesn't happen right away, only after I've made a few changes. Does anyone have any ideas on what's happening?? Thanks in advance. Kevin Smith

True, but the stored procedure I am calling is intended to return many rows of data (tens of thousands on occasion). I need a cursor for that. >On Thu, 29 Jun 2000, David A Lipsky wrote: >> curs = conn.cursor() >> conn.procedures.some_stored_procedure(curs) > > Do not pass cursor - pass parameters to the procedure and it returns a >result. > >Oleg.

[lines] element in "property sheets" ++ \345 29 \345r ..
by Jørgen Skogstad 29 Jun '00

29 Jun '00

Kindest.. I have object contained in ZObjects .. and I have some object "parsing" the contents based on a search.. The type in the property sheet is; [text] Beneath is the dtml code used to print the main content of the type mentioned above .. <tr><td><b>Annonse tekst:</b></td><td><dtml-var annonse_tekst newline_to_br></td> .. my problem is that the final output when parsed with the dtml code above is something like; ['hei', ' jeg er .. p\345 29 \345r som s\370ker ..... ...angre seri\370st ment. ']</td> .. how do I get ouput without the ['<text>'] .. entries.. that is; "clean output" .. as well as how can i get the ascii codes like \345 to be the correct html code for norwegian caracters? Would apriciate any input here.. Thanks in advance. Kindest, Jørgen Skogstad
