Re: [Zope] ZOPE and DEBIAN INSTALLTION

Hi Yes, I actually try to deinstall the latter "apt-get version" that I installed via source. But your solution does not work. After "reading the pakets", it is always said that the system could not find the paket "zope_2.6.4-1_i386.deb". The weird thing is that this paket is actually on system; I can even see it in my root directory! Do you know what problem is?

Problem with hasattr() and Zope 2.8.1
by Doyon, Jean-Francois 01 Oct '05

01 Oct '05

Hello, I'm using new-style classes and properties to implement multilingual support in my objects. I might therefore have something like: mything = property(__get_mything) def __get_mything: return self.__mything_en (Extremely simplified!) This works fine. Now however I'm discovering that doing a hasattr() on anything that starts with 2 underscores always returns false! So hasattr(self, '__thumbnail') doesn't work as expected, but hasattr(self, '_thumbnail') DOES! (All other things being equal of course). I've successfully tested this by replacing this code, which didn't work as expected: def __get_thumbnail(self): if not hasattr(self, '__thumbnail'): self.setThumbnail() return self.__thumbnail else: return self.__thumbnail With this one: def __get_thumbnail(self): try: return self.__thumbnail except: self.setThumbnail() return self.__thumbnail Which DID work as expected (Though I suspect the try ... except might be faster anyways!) ... I checked the Collector: http://www.zope.org/Collectors/Zope/collector_contents?searching=yep&Searcha bleText=hasattr&status%3Alist%3Aignore_empty=Accepted&status%3Alist%3Aignore _empty=Pending Nothing jumped out at me as being relevant ... Any ideas?

ZRS Now Available for FREE 30-day Evaluation
by Brian Lloyd 01 Oct '05

01 Oct '05

Hi all, We are happy to announce that Zope Corporation is now offering Zope Replication Services (ZRS) in a 30-day evaluation format! For more information and to download the evaluation release, visit: http://customers.zope.com/ZRS/ About ZRS: Zope Replication Services (ZRS) increases the reliability of all Zope enterprise clusters and eliminates the storage system as a single point of failure. Sites with high availability requirements must manage planned and unplanned downtimes. Planned outages include system maintenance, software / operating system upgrades, and backups. Unplanned outages include hardware and network failures. ZRS reduces the downtime associated with these events by replicating and distributing mission-critical data storage across distinct physical storages (possibly in distinct geographic locations). Should a primary storage fail, a secondary storage can take its place. Secondary servers can be taken off-line at any time to undergo repairs, backups, or system upgrades. When a secondary returns to service, it automatically resynchronizes with the primary server. ZRS also improves scalability since secondary servers can optionally provide additional read-only ZEO connections while maintaining their replication functions. ZEO client storages can be configured to connect to any available secondary, and can be load-balanced among the available secondary ZRS servers to implement highly-available and highly-scalable Zope clusters. ZRS is a 'battle-tested' solution that has provided the high-availability and disaster recovery solution critical to large-scale public and internal Zope deployments for years. Premier brands including the VIACOM radio and television group, AARP, Community Newspaper Holdings Inc. (CNHI), and the Joint Intelligence Center, Pacific (JICPAC) rely on ZRS to ensure reliability and scalability for their mission-critical Web sites. The 30-day evaluation release allows organizations to install and operate ZRS on up to five primary ZODB servers and on an unlimited number of secondary servers for up to thirty days. The current evaluation release (ZRS 1.4.2) is compatible with Zope versions 2.4 - 2.7. Full releases of ZRS compatible with Zope 2.8.x and Zope 3.x are also available.

External Method Working Directory?
by jwithers 30 Sep '05

30 Sep '05

Folks, I have an external method that at this point is made up of nothing but os.getcwd() and lives in my Extensions directory. When it is run, it reports the working directory as being one of my Products directories. Can anyone tell me what the default working directory for an external method is? Further, I need this to create a file temporarily in Extensions. I would prefer not to have to hardwire the location of Extension into the code, since that would make the script non-portable to other instances easily. Any advice on this would be appreciated. J. P.

cut&paste from one mounted storage to another
by M. Krainer 30 Sep '05

30 Sep '05

Hi! Is there a possibility to cut&paste from one mounted storage to another? I have a filestorage Data.fs mounted as / and another filestorage Archive.fsmounted at /site/Archive. When I try to cut&paste an object from e.g. /site/foo/bar to /site/Archive/bar I get an InvalidObjectReference Exception: File "/opt/Zope-2.8.1/lib/python/ZODB/Connection.py", line 503, in _commit self._store_objects(ObjectWriter(obj), transaction) File "/opt/Zope-2.8.1/lib/python/ZODB/Connection.py", line 525, in _store_objects p = writer.serialize(obj) # This calls __getstate__ of obj File "/opt/Zope-2.8.1/lib/python/ZODB/serialize.py", line 330, in serialize return self._dump(meta, obj.__getstate__()) File "/opt/Zope-2.8.1/lib/python/ZODB/serialize.py", line 339, in _dump self._p.dump(state) File "/opt/Zope-2.8.1/lib/python/ZODB/serialize.py", line 281, in persistent_id raise InvalidObjectReference( InvalidObjectReference: Attempt to store an object from a foreign database connection Am I doing something wrong or is this simply not possibly resp. is there a workaround to do a cut&paste between storage boundaries? Thanks. -- mkrainer

emergency access problems
by michael nt milne 30 Sep '05

30 Sep '05

Hi I appear to be having difficulty logging into the ZMI using the password created on install. I did change some settings to my root login using the Samplex member product etc but didn't change the password, login etc. Anyway I've followed all the instructions in security.txt, telnetting in as the user that made the zopeinstance and running python zpasswd.py access using SHA-1 and then entering nothing for domains ( I presumed that this would give access for all domains etc) I then get an access denied message on running this and the access file is not created. Any help would be appreciated. I guess I can always create a new zope instance and delete the old one?

ZEO clients eating up / filesystem
by Reinoud van Leeuwen 30 Sep '05

30 Sep '05

Hi, We have a ZEO setup with a Plone based intranet, and for some reason it seems that Zope is filling up space in the root filesystem. I have to restart Zope twice a day to clear it up (restarting Zope clears up the space). lsof does not list anything open in the root filesystem and swapping is done in the swap partition. Has anyone observed the same and found a solution?
