[Duplicity-talk] Timeout question

[Ken Bass]

I've been trying to use the new backend I've been working on for the 
past few days and have been having an issue. I had a few questions
(I'm on dupl 0.17 and python is 2.4.3 (Centos 5))

I am getting a RESTART due do an upload timeout (see later question). 
What I see is that duplicity appears to download the first
vol1 and then deletes is. Is something done with this? It seems like a 
wasted download of 100MB. If it just needs the size, it was already 
returned in the listings.

Found primary backup chain with matching signature chain:
-------------------------
Chain start time: Thu Jan  5 21:53:16 2012
Chain end time: Thu Jan  5 21:53:16 2012
Number of contained backup sets: 1
Total number of contained volumes: 57
 Type of backup set:                            Time:      Num volumes:
                Full         Thu Jan  5 21:53:16 2012                57
-------------------------
No orphaned or incomplete backup sets found.
RESTART: Volumes 57 to 58 failed to upload before termination.

2) I tried grepping the code for 'RESTART' and 'Restarting' and found 
nothing related to the above prints. Is this part of duplicity or 
somewhere else? I was trying to figure out why it downloads that vol1 
file each time and then throws it away.

3) Every time it resumes and re-uploads the file, the file is different. 
Is that because of GPG? Does each invocation of GPG, with the same 
passphrase, produce a different output?

4) When uploading a file via my put method, I am *occasionally* getting 
a timeout. This is basically an HTTPS POST that I had to add a handler to
support 'multipart/form-data' encoding.

Is this what the --timeout command line option is for? To tune the 
default socket timeout?

I log into the file storage service and manually download the file and 
it is actually completed and an md5sum compares on the files, so I think 
duplicity is not waiting long enough. It appears duplicity sets the 
timeout to 30 seconds. I noticed on my last upload, it took 78 seconds 
before the server responded with the little XML response telling me OK.

Thanks
