This issue to address the middle issue, the Get Record issue below.
-----Original Message----- From: Péter Király [mailto:kirunews@gmail.com] Sent: Thursday, April 26, 2012 5:40 PM To: Cook, Randall Cc: Delis, Christopher; Arbelo, Ralph; Lindahl, David; Wesley, MT Subject: Re: another MST error?
I guess my reports were not clear enough. We have three different bugs:
- the initial harvest contains deleted records. I guess it should not contain deleted records, becuse according to my reading of the standard, the deleted records means changing from a previous version. But there is no previous version before the initial one. It causes a not too serious performance problem in Drupal Toolkit.
- the GetRecord issue. I think it is clear for all of us. It doesn't cause any problem in Drupal Toolkit, since we do not use it right now. However I am planning to use it in the future, to provides link to MST, if the admin wants to check a record.
- the zero length answer for ListRecords. When yesterday I ran into it, it blocked the Drupal Toolkit. Now I followed the tactics, that DT tries to reqest it once again (up to 3 times), and it stops DT harvesting only if all retrials failed. The current full harvest met this problem only one time, and the first retrial were successfull. Now I changed the code, that if it will happen again, DT logs the full HTTP response including headers, so I can give you more details. I am not sure whether it is MST problem or not, since Ralph reported, that nothing has been recorded in MST log.
Hope this helps.

Chris, I think it is fine to do. And thanks for your help, I absolutely appreciate it.
Up until now, Peter has usually only done controlled harvests. For example, full harvest from a T0 state, that didn’t contain any deletes. Then, in T1 and T2, the deletes he got were true deletes. Now he is harvesting from a live MST that has been in operation for a while, and with his initial harvest request, the “give me everything� request, it is returning all the deletes that have happened. I am not clear on why this in general is causing a problem. So Peter tried to look at a specific record that is deleted, and got the 0 length issue.
Peter, the Get Record when you list the ID of a deleted record seems like a bug in general and should be fixed, but is this really a “stopper� problem for you? In a typical harvest request from DT, you would never specify the metadata id would you? It’s always a date range. Can you elaborate in the “stopper� here in case I am not the only one confused.
