`Blob.upload_from_filename` fails silently if the blob name starts with '/'

[tillahoffmann]

Using google-cloud-storage==1.2.0, attempting to upload files using Blob.upload_from_filename fails silently (i.e. no error is raised but the blob is not uploaded) if the blob name starts with a forward slash /. A basic example is given below.

import google.cloud.storage

client = google.cloud.storage.Client()
bucket = client.get_bucket('some-bucket')
blob = bucket("/some-blob")
blob.upload_from_filename("some-file")

Whoa! Thanks for the bug report @tillahoffmann, I'll look into it.

I can't reproduce:

>>> bucket = client.create_bucket('gcp-issue-3675')
>>> list(bucket.list_blobs())
[]
>>> blob = bucket.blob('/some-blob')
>>> blob.upload_from_filename('/tmp/gcp-issue-3675.txt')
>>> 
>>> blob.exists()
True
>>> [b.name for b in bucket.list_blobs()]
['/some-blob']
>>> blob.download_as_string()
b'Now is the time for all good men to come to the aid of the party.\n'

@tillahoffmann Can you give us the exact code so we can attempt to reproduce?

[tillahoffmann]

@lukesneeringer, sorry that this has taken me so long. I'll try and get a reproducible example to you by the end of next week.

[lukesneeringer]

@tillahoffmann Not a problem.

I am going to close the issue in the meantime, just for tracking sanity. Feel free to reopen when you have a repro case. :-)

I can no longer reproduce this issue using 1.3.0.
