Zope pretends to receive and send XMLRPC data, but strace sees nothing !

Hi, I have an ajax application that is composed by : 1) An ajax client which is a web page with a button that calls a zope object's method, say "toutCompter". 2) An ajax server (zope), with a zope object that has the method "toutCompter" (all zope object methods are XMLRPC callable right ?). I use two browsers on two separate machines. I call the methode on the two browsers, and compares the zope trace and strace output of the network activity. The problem is that zope says he sends data but strace don't, and zope says he receives data and again strace don't. This is the zope/python code that prints to the console : <zope/python> def toutCompter(self): """ this method is called via XMLRPC. """ IPAdresse = self.REQUEST["REMOTE_ADDR"] print "ip:",IPAdresse,"requests counting of lines",self.getForm ('min'),"to",self.getForm('max') ... #some processing here. creation of XMLData print "sending results to "+IPAdresse return XMLData </zope/python> Zope says : <zope traces to the console> ip: 10.75.49.155 requests counting of lines 10 to 20 ip: 10.75.49.51 requests counting of lines 10 to 20 sending results to 10.75.49.155 sending results to 10.75.49.51 ip: 10.75.49.51 requests counting of lines 10 to 20 sending results to 10.75.49.51 </zope trace> while strace says (SIGRTMIN were stripped out, are they of any use here ?): <strace> recv(24, 0x8d1e7e4, 4096, 0) = -1 ECONNRESET (Connection reset by peer) recv(24, "POST /aef/rechercheMultiligne/to"..., 4096, 0) = 686 recv(28, "POST /aef/rechercheMultiligne/to"..., 4096, 0) = 649 recv(28, "requete_11=%2410%20and%20ptel%20"..., 4096, 0) = 445 send(24, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 666, 0) = 666 recv(24, 0x8ebac04, 4096, 0) = -1 ECONNRESET (Connection reset by peer) send(28, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 643, 0) = 643 </strace> As you can see, the first part of the zope trace: ip: 10.75.49.155 requests counting of lines 10 to 20 ip: 10.75.49.51 requests counting of lines 10 to 20 corresponds to this part of the strace : recv(24, 0x8d1e7e4, 4096, 0) = -1 ECONNRESET (Connection reset by peer) recv(24, "POST /aef/rechercheMultiligne/to"..., 4096, 0) = 686 <comment> WHERE IS POST DATA FOR SOCKET 24??? </comment> recv(28, "POST /aef/rechercheMultiligne/to"..., 4096, 0) = 649 recv(28, "requete_11=%2410%20and%20ptel%20"..., 4096, 0) = 445 This part is ok. XMLHTTPRequest data is sent, saying :"hello ! i request the toutCompter methode. This is the post-data that you need to process my query. Thanks folk, seeya !". Now the second part is wierd, because the zope trace and strace DO NOT MATCH : <zope trace part II, sending data back to XMLHTTPRequest> sending results to 10.75.49.155 sending results to 10.75.49.51 ip: 10.75.49.51 requests counting of lines 10 to 20 sending results to 10.75.49.51 </zope trace> <strace part II, data sent only to one machine !> send(24, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 666, 0) = 666 recv(24, 0x8ebac04, 4096, 0) = -1 ECONNRESET (Connection reset by peer) send(28, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 643, 0) = 643 </strace> let's match line by line : ===================================================================================== zope strace ===================================================================================== sending results to 10.75.49.155 => send(24, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 666, 0) = 666 sending results to 10.75.49.51 => you are such a liar ! no data was really sent ! ip: 10.75.49.51 requests counting of lines 10 to 20 => WHAT ? there's no recv at all !! except for the reset ! sending results to 10.75.49.51 => send(28, "HTTP/1.1 200 OK\r\nServer: Zope/(Z"..., 643, 0) = 643 ===================================================================================== This behaviour is repeated every time i use two browsers, be it on the same machine or on two separate machines. It all seems like zope would save the xmlrpc requests in a buffer and process on of the requests many times (sometimes more than twice !), or something alike. I would like to notice here that I use Zope 2.9.0 in single thread mode and python 2.4.2 I would really appreciate anybody's comment on this strange brehaviour. Thank you. Y.Chaouche

pool_size
by Brian Sullivan 18 Jan '07

18 Jan '07

I am having a problem with zope 2.9.4 occasionally pegging the CPU and thereafter being unusable -- there are some indications in the event log that this is related to "pool_size" being too small. Lacking any other strategy to determine the cause of the problem, I am considering experimenting increasing "pool_size" to see what effect it has. A search returns some inprecise information on how to do this. My understanding is that this can be modified in the zope.conf for the instance. Can anybody give me precise information on modifying this parameter or point me to a concise resource on configuring the zodb in general,

optimize old code
by Yuri 17 Jan '07

17 Jan '07

Hi! I've an old product, based on zclass and zope 2.6, I would like to optimize (as possibile) the insert and cataloging of a zclass. Now I use this scripts: form that creates the request -> -- <dtml-let ut="_.SecurityGetUser().getUserName()"> <dtml-with "manage_addProduct['Dafne']"> <dtml-with "dafne_item_add(_.None,_,NoRedir=1)"> </dtml-with> </dtml-with> </dtml-let> -- <dtml-with "dafne_item.createInObjectManager(REQUEST['identificativo'], REQUEST)"> <- just set an id for the class <dtml-call "propertysheets.metadati.manage_editProperties( REQUEST)"> <- edit properties <dtml-call "manage_permission('Cambia il contenuto dei dafne',('Manager','Owner',),acquire=0)"> <- set permission and roles <dtml-call "manage_addLocalGroupRoles(ut,['guardone'],REQUEST)"> <dtml-if expr="pubblici == '1'"> <- anonymous can view? <dtml-call "manage_permission('View',('Anonymous',),acquire=0)"> <dtml-else> <dtml-call "manage_permission('View',('Manager','Owner','guardone',),acquire=0)"> </dtml-if> <dtml-call "manage_permission('Change Images and Files',('Manager','Owner'),acquire=0)"> <dtml-call "manage_permission('Add Documents, Images, and Files',('Manager','Owner',),acquire=0)"> <dtml-call "manage_permission('Add ExtFiles',('Manager','Owner',),acquire=0)"> <dtml-call "manage_permission('Change ExtFile/ExtImage',('Manager','Owner'),acquire=0)"> * Can optimize here? * <dtml-call unindex_object> <- my catalog is not called Catalog but catalog, so I've read I've to do this three steps <dtml-call "manage_editCataloger('catalog', REQUEST)"> <dtml-var index_object> * * </dtml-with> * do redirecting* <dtml-comment> Now we need to return something. We do this via a redirect so that the URL is correct. Unfortunately, the way we do this depends on whether we live in a product or in a class. If we live in a product, we need to use DestinationURL to decide where to go. If we live in a class, DestinationURL won't be available, so we use URL2. </dtml-comment> <dtml-if NoRedir> <dtml-else> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect( DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect( URL2+'/manage_workspace')"> </dtml-if> </dtml-if> --- Any idea? TIA!

Path Level in Catalog
by KJZZ Webmaster 16 Jan '07

16 Jan '07

I recently had to rebuild our catalog using the manage_catalogFind form in the ZMI. In this case, I simply selected the object types that I wanted recataloged, then clicked the "find and catalog" button. However, I now notice that almost every object that was found is entered into the catalog twice, once with the relative path from the top of the site, and second with a path that begins above the folder in which the site is contained, such as: 1) /myobject/ 2) /mysite/myojbect Tell me, does anyone have any suggestions for an expression to find and catalog only objects with the first path and omit all objects starting with the second path. Any advice is appreciated. John T.

FTP acquisition problem with Zope 2.10.1
by Marcus Schopen 16 Jan '07

16 Jan '07

Hi, I've installed a fresh Zope 2.10.1 and noticed a strange behaviour when connectiong via FTP: Through the ZMI I've created a Folder /A with a DTMLDocument "a" and an empty Subfolder B: / -/A ---a -/B If I connect via FTP to the server and trying to upload an ASCII file "a" to the folder /A/B it overwrites the "a" object in the parent A folder and does not create a new "a" object in the /A/B folder. An old 2.7.3 Zope doesn't show this acquisition behavior. Cheers, Marcus
