[Zope] ZOracleDA causing instability
Hi, Just wondering if anyone else sees this: I run a moderately high-traffic (a couple hundred thousand hits/day) with Zope and Oracle (most of the site is forms interacting with the Oracle database, the rest being help/support files for those forms and a couple images). Products used: - FSSession-0-4-2 - GenericUserFolder 1-2-4 - PythonMethod-0-1-7 - SiteAccess-2-0-0b3 - the latest ZOracleDA (the __version__ string in __init__.py says: "$Revision: 1.4 $") Zope 2.2.2 (source release) run with RewriteRule proxying behind apache 1.3.14. Oracle 8.1.6 (aka 8i release 2) installed on the same machine. The problem is that the whole thing is very unstable, and I suspect ZOracleDA to be the culprit. Sometimes the whole Zope just hangs (actually so often, that we are restarting it from cron each 15 minutes, but it's a bad solution since all the GUF cookies are lost and customers are logged out), other times it goes mad and eats lots of memory (I've seen it consuming 800 megs of memory, and the whole unpacked Data.fs is 9 megs!), other times it gives a very strange error: ZSQL methods raise exceptions whose contents is queries ran in other threads!.

[Zope-dev] RFC: page contracts
Hi eveyone. While playing around with the development version of ACS (ArsDigita Community System), I noticed a very nice feature they introduced, namely page contracts. In ACS, this means that every tcl page starts with a call to ad_page_contract. In the parameters passed, you specify: - general page documentation (what it does) - author(s) - creation date (not needed for Zope since we have bobobase_modification_time) - CVS ID (not quite applicable for Zope (yet?)) - the expected input variables (from forms) along with their default values (where applicable) and types (having a couple of types like "integer" and "string" predefined and an easy-to-use plugin system to add custom types) - an optional validation block in which you can check the input data ranges and validity (you can also make validation rules depend on each other so if one fails, the rules which depend on it aren't tried) - an optional custom error messages section (to use when one of the required input variables is not there or does not match the format, or when a validation block fails). If you don't provide this some reasonable defaults are provided. IMHO, such a feature would be very useful for Zope too. I find myself quite often doing input validation and error handling in DTML, which is (to say the least) painful. I would be interested to give a try at implementing this, but before starting I wanted to hear community's opinion on: - whether this would be useful - how this should be aproached (the two possibilities I have in mind until now are either a separate manage tab for the page contract, and there a HTML-based interface for building it, either a dtml-contract tag which surrounds the page contract (written in python probably) and placed at the top of DTML documents/methods). -- Petru Paler, mailto:[EMAIL PROTECTED] http://www.ppetru.net - ICQ: 41817235 ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Request for comments: Directory storage
It would be great if you could do it, but beware that you will be benchmarking a lot of overhead if you only plan to measure storage performance. Why not use ZODB directly ? If I talk HTTP, it measures things fully - Python's interpreter lock will mean a storage system written in python will benchmark better without having to compete with ZServer, and vice versa for storage systems with non-pythonic bits. Yes, you are right. What filesystem does that use ? No idea :-) Something log based that is very fast and handles huge directories happily. It also appears that another member of this list has an EMC Symmetrix box to test on, which I believe is the next (and highest) level up from a Netapp. Mmmm... I heard that Network Appliance hired a couple of the SGI engineers that designed XFS ? I've attached a prerelease alpha of zouch.py for giggles. Not even a command line yet, so you will need to edit some code at the bottom. The current settings generate about 360 directories and about 36000 files, and proceeds to make about 18 reads. This bloated by test ZODB to just over 200MB and took about 2.6 hours attacking my development Zope server from another host on my LAN. Cool :) Thanks for writing this, it will be very useful for benchmarking. -Petru ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Request for comments: Directory storage
Hello all, You probably saw my yesterday post with the first alpha of ReiserStorage. One of the questions that people tend to ask about it is wheter they can use it without reiserfs. There are two problems with not using reiserfs: 1. ReiserStorage (now renamed to DirectoryStorage) stores each object in a separate file and *all* the files in a single directory. This was done in order to let the filesystem what it was meant to do: store and retrieve files quickly. While reiserfs is *extremely* good at this (it uses a btree to store directory entries), most other filesystems do linear searches when finding a file so performance is very bad when you have many files in a single directory. This problem can be solved by splitting files into multiple directories when not using reiserfs. This would add a little overhead but it is tolerable. 2. Waste of space. Typical block-allocation filesystems like ext2 and FAT will waste alot of space in the usage pattern of DirectoryStorage. ReiserFS packs small files together in the btree, so it solves the problem, but I have no ideea how this could be fixed easyly on the other fs's. Comments ? Suggestions ? PS: a new DirectoryStorage release will be done today, with bugfixes and new features. -Petru ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] ReiserStorage 0.01 alpha
Hello all, Attached you can find the code for a preliminary ZODB storage manager which is designed to take adventage of the reiserfs filesystem (http://devlinux.com/namesys). While it is usable on other filesystems too, the performance will decrease as the number of objects in your database increases. Comments: 1. This is as alpha as it can be. While it is usable to do some testing on a spare Zope, you must be insane to even try to use this on a production system. 2. A generic DirectoryStorage is comming soon, with the diference being splitting files by directory (and, of course, being slower than the reiserfs version). 3. As you can see in the source, I/O errors in critical points can corrupt the storage. 4. It currently does not support versioning and undo. I'm working first on getting it stable and fast, and then add these features.
