backblaze's Issues

Error in accessing files from bucket

Dear developers,

Given the actual release of this Backblaze (branch master) package, there are some small typos in the bucket/blocking/init.py module.

The errors are in the "file_versions" and "file_names" methods.

Instead of using NextFilename as an attribute of the file object, one must use "fileName"; also, the "nextFileId" returns a typeError.

Sincerely,

How to download files from backblaze using the current package?

Dear developers,

Despite my efforts, the current python's package does not seem to allow an easy download API from BackBlaze.

Would it be possible to insert some examples in your webpage so to facilitate this package usage?

Sincerely

How can I upload the failed files again?

When I use asyncio to upload dozens of files concurrently, the following errors often occur. I use Ubuntu system. How can I upload the failed files again?
`uploadtasks = [bucket.upload_file(UploadSettings(channelid + "/" + singlepath.name),singlepath) for singlepath in collectpath if singlepath]

filemodel, waittingfile = await asyncio.wait(uploadtasks)

print("WWWWWWWaiting", waittingfile)

if not waittingfile:
return True`

Problems in deleting a AwaitingFile from bucket

Dear developers,

I have noticed that it is not so easy to delete a given bucket's file (a.k.a., an AwaitingFile object) from BackBlaze.

It seems that the AwaitingFile does not have a filename as an attribute that could be easily assessed for invoking its inherent "delete" method.

Therefore, if possible, I believe that the method "delete" from the AwaitingFile object could be reformulated in such a way that no "filename" is required from the user. This parameter should be directly accessible as an attribute of the class' instance. After all, it is of common understanding that the file to be deleted is itself, and not some other file; thus, no name should be required for its own deletion from Backblaze.

Let me know your thoughts.

sincerely,
