"REQUEST['REMOTE_ADDR']".
Note, however, that it is not too difficult to forge it.
Moreover, when you put another web server in front of Zope (recommended),
then "REMOTE_ADDR" may contain the IP address of this proxy.
Apache provides a way ("proxy_via") to make the correct address
available (up to forging).

Since you're getting no traceback info of any kind, it's impossible from what you've said so far to guess whether the problem is in StringIO or in DbiRaw's __str__ implementation.

This is indeed the case: The code you mentioned prevents the modification (i.e. "commit") of an object that caused a "ReadConflictError" when it has been accessed -- whether or not the exception has been caught or not. Shane seems to want a stricter behaviour: something like: def commit(...): ... if self._conflicts: raise SpecialConflictError(...) i.e. prevent the commit, when the transaction saw any conflict whether or not it tries to modify such an object. However, I think his wish is not necessary. Even when a "ReadConflictError" was swallowed, the object has not been read and its state is still undefined. Whenever the application tries to read an attribute, the object is refetched and the "ReadConflict" reissued. When the conflict successfully trickles down to the "commit", then in fact, the transaction was independent from the state of the respective object... The only thing, the application can do is do write the object. However, "writing" implies fetching the object -- with the consequence of another "ReadConflict" (if I am right, then the code in "commit" is redundant, as the application is unable to write an object that could not be fetched due to a "ReadConflict"). The problem that remains: The application swallowed an exception and, as a consequence, did not recognize that it was unable to *write* an object. It performs its other writes and commits. In this case, the originally written object remains unchanged and inconsistent with respect to other objects. Shanes wish would recognize this situation. Obviously, I have to retract my previous thought :-) -- Dieter ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

That's even better! However, we may still be interested to get an exception unswallowed by "hasattr". Usually, there is some sense in not continuing an expensive computation when we know it will finally fail... When we fix ZODB, we should note that information about the precise cause is helpful in fixing the underlaying problem.

[Zope-dev] 2.7 series dropped PASV_FTP_PORTRANGE
In the 2.6 series I submitted a patch to support specifying the range of tcp ports to use on the server for pasv ftp transfers. I still need this functionality, but I see that the "environment variable hack" isn't in medusa/ftp_server.py I thought perhaps something in zope.conf would specify this, but it seems not to be there. In fact, I see no clean way to pass port range information from ZServer.FTPServer to medusa.ftp_server (hence why we used an environment variable hack in the past) For my use case, the pasv port range is always "near" the range used by the listening ftp daemon anyway, so a simple solution for me is to look at the control connection port and just find an open port that is "nearby". However the better solution, I suppose, is to allow the port range to be specified in zope.conf. But what's the best way (architecturally) to cleanly get this information into medusa's ftp_server.py module? -- Brad Clements,[EMAIL PROTECTED] (315)268-1000 http://www.murkworks.com (315)268-9812 Fax http://www.wecanstopspam.org/ AOL-IM: BKClements ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
