Sending MIME with Mailhost
by Kevin Carlson 15 Nov '02

15 Nov '02

Is there a way to send email attachments using a mailhost in a python script? I've seen the example that uses an external script with smtplib and the examples that use the <dtml-sendmail> and <dtml-mime> tags. I would really like the flexibility that comes with using a python script, however. Anyone have any ideas? Thanks, Kevin

Data.fs falls into 33GB hole
by Howard Hansen 15 Nov '02

15 Nov '02

I have several, fairly-large sites running on my machine and at the last backup, my Data.fs file stood at 340MB. Zope itself only took up 50MB of RAM, so I didn't worry about the size of the file. Disk space is essentially infinite nowadays, right? Yes, but imagine my shock when I checked out why my backup routine took a long time and then failed. I found that Data.fs took up 33GB of space on the disk! Yikes! I must step back for a moment and salute everyone who made this possible. Everyone at Zope, Linus, Guido, Maxtor, AMD, Intel, and the manufacturers of all of the little components who have conspired to make a sticky mess like this possible. My Data.fs file grew to 33GB and I DIDN'T NOTICE. Looking over the Undo lists, I found hundreds of transactions that said simply "by Zope". Some experimentation led me to discover that these were inserted by JRedirector. It summarizes redirections, and my assumption that it did it under the Undo radar proved incorrect. I've since disabled JRedirector. Running df on my disk, I find that I've filled 74% of the 55GB data partition, so there's no chance of making a copy locally and figuring it out from there. Serendipidously, I did have a 60GB drive literally sitting on the shelf. I popped it into my Windows PC (I'd been able to get fsrecover.py to run on it, but not on the Linux box) started copying over the network This took a couple of hours. I tried to run fsrecover on the big file and it failed immediately: > python.exe fsrecover.py -v 2 -P 184000 j:\Data.fs j:\Data_recovered_all.fs Recovering j:\Data.fs into j:\Data_recovered_all.fs Traceback (most recent call last): File "fsrecover.py", line 328, in ? if __name__=='__main__': recover() File "fsrecover.py", line 221, in recover seek(0,2) IOError: [Errno 22] Invalid argument I guess there are indeed some limits. I wrote a quick program to make a copy of the first 1,000,000,000 bytes of the file. I ran fsrecover on that without problems. This tells me that the file itself is OK. It just needs to be packed or filtered. I've got thousands of good transactions interspersed with tens of thousands of noise transactions. Questions: 1) Can I safely pack a database this huge on my live machine? 2) If that doesn't work, can I easily figure out transaction boundaries? If so, I could either chop the big file up into smaller chunks and serially attach new tails to the file, then fsrecover the whole thing. 3) If I can figure out transaction boundaries, can I filter out transactions by type? I've got approximately 32GB of JRedirector transactions that I'd be happy to remove. As always, thanks for listening and I eagerly await your wisdom.

Basic DTML syntax question- variable value test
by Kelley, Sean 15 Nov '02

15 Nov '02

I am trying to test the value of a variable and do something if it is true. When I say: <dtml-if "AppRecDate == '1900/01/01'"> <input type="text" name="AppRecDate" size="12" value="" tabindex="13"> <dtml-else> <input type="text" name="AppRecDate" size="12" value="<dtml-var AppDelDate>" tabindex="13"> </dtml-if> I get the false condition. That is, value="<dtml-var AppDelDate>" is used in the input statement. If I output the value of the variable directly, I get that it is equal to "1900/01/01" with the following code: <dtml-var AppDelDate> What am I missing in my use of the syntax?

extract elements from xml-documents
by Einar N�ss Jensen 15 Nov '02

15 Nov '02

I have tons of framemaker-documents converted to xml from which i would like to extract information inside certain elements. a portion of the document (english.xml)would typically look like this: <emne> <a href="#44332"></a> HF2345 </emne> what i would like to extract in two separate strings is: "44332" and "HF2345" How is this best accomplished? the document does not reside inside zope but is located on another webserver. Thank you all in advance! Einar -- http://www.idi.ntnu.no/~einjen/ http://vader.hf.ntnu.no/ Einar Næss Jensen tlf:90990249/73526716

Re: how to use datetime
by Paul Tiemann 14 Nov '02

14 Nov '02

Hi Jonatan, If you need easy-to-use DateTime objects, I'd suggest mx.DateTime package -- search for 'mx.DateTime' on google to find it - it's a lot easier to work with those DateTime objects, especially for rules like adding or subtracting a whole week, when the week crosses daylight savings time rules, etc... It handles it all very elegantly. Just my 2c. -- Paul

RE: [Zope] Regarding ZOPE backup procedure
by sean.upton＠uniontrib.com 14 Nov '02

Also worth considering: figure out a way to back up your content in a format other than just backing up your ZODB (serialize it and download it via FTP or something). Consider some way to serialize your CMF content into something like plain-text files so that you not only have a backup of your database, but also a neutral (archival) backup of your content as well. For backup of your ZODB, consider use of DirectoryStorage.

Use DirectoryStorage! http://dirstorage.sf.net It uses files in deep directory structures to comprise persistent objects in a ZODB storage alternative to a single FileStorage Data.fs. Incremental backups using standard unix command line tools (i.e. tar or cpio), snapshot functionality, scalable packing without massive memory consumption: an inexpensive means for replication and high-availability clustering of a ZEO storage server. What's not to love?
