The same behavior happens with a simple string write:
In [8]: with gcsfs.GCSFileSystem(project=project).open(f'{bucket}/test.txt', 'w') as f:

But weirdly enough, changing the write type to binary resolves this:

I'm trying to remember off the top of my head if this is new behavior but I'm not sure.

Ancillary issue that would likely be linked to #59
As per the module documentation oauth2client
is officially deprecated in favor of google-auth
. As google-auth
is an officially support project with a stable API, any further development of the gcsfs
authorization system should target this library.
The current oauth implementation should likely replaced via a standard implementation using google-auth
for token managment and the related google-auth-oauthlib.flow
for device authorization.
GCS provides size and md5 hash information on written files. At the minimum, the former should be checked against the expected upload size, and optionally the md5 also for a stronger guarantee.
Is it possible to make one release of the library on pypi?
Currently mkdir on a subdirectory fails with a non-informative error. It would be nice if this either worked (if that even makes sense) or else raised an informative "actually you don't need to do this" error.

Looking around on the internet, people seem to suggest that I enable OAuth on my account. This seems odd though because this didn't seem to be necessary before. Any thoughts on what might be going on?
If gcsfs is to be used in the context of dask, it should not pass around the authorization token when pickled. Instead, we should require the user to have distributed a token file to each machine beforehand or otherwise set up permissions on each node, as we do for s3fs.
It'd be nice to be able to use this library just using gcloud's default credentials, instead of having to juggle files.
I regularly access Google cloud services with two different google accounts. I typically switch between them by using gcloud auth login
and then selecting the different account. However, even after doing so the gcsfs
library is finding connection information for my other account. What logic does gcsfs use? I'm interested in tracking down from where it's getting its tokens.
See dask/dask#2207 for dealing with complex URIs. Given that there is no current way to include user/path in a GCS URI, this may just be a no-op, but should be considered.
more a question than an issue: I found this while looking for a s3fs (dask/s3fs) alternative to be used as zarr backend. We are looking to make our processing less dependend on AWS. Would you say gcsfs is already useable as a s3fs replacement for zarr?
(edit: sorry for the confusion, I typed 's3ql' instead of 's3fs' the first time. Corrected now.)
When using gcsfs in master it is difficult to detect what commit I'm on. Any thoughts on switching to using versioneer for versions? Dask and distributed both do this and could serve as models.
I have faced several times the same 502 error when writing in chunks. Errors are sporadic and look like:

Google writes this may happen when system/network is under stress - our script does indeed read and write from GCS
several GB of files in chunks after on-the-fly transformations.
Look at Handling Errors
at https://cloud.google.com/storage/docs/json_api/v1/how-tos/resumable-upload.
They indicate to implement exponential-backoff
: https://cloud.google.com/storage/docs/exponential-backoff
Is this something that can be implemented in GCSFS
i.e. resubmit a chunk when such 5xx
error occurs ?
If not, wrapping the write statement in a try/exception, delete the target file written so far and reprocess is not an option for me. Because the records I write are based off data in a compressed GCSFS
-file I read. ZipFileExt are not seekable so what is read is gone. I would have to delete the whole batch and restart.
@quasiben and I conda-installed gcsfs in a fresh environment. We found that we needed dask-core and toolz for things to function properly.
The implementation of walk in gcsfs
returns a flat list of all paths encountered when traversing the tree. In contrast, os.walk
from the standard library returns an iterator of dirname, dirs, files
, where dirname
is the current directory prefix in the traversal, and files
and dirs
are the names (relative, not absolute) of all files and directories respectively.
This difference in behavior is confusing for those familiar with the standard os.walk
method, and also makes providing the interface used by pyarrow
(which does match the standard library) tricky.
After overcoming #82, I am on to a new error.
I set my GOOGLE_APPLICATION_CREDENTIALS
to point to an appropriate .json file. I verified that the config is working with the following code
In [10]: from google.cloud import storage
In [11]: storage_client = storage.Client()
In [12]: list(storage_client.list_buckets())
Out[12]:
[<Bucket: pangeo>,
<Bucket: pangeo-data>,
<Bucket: pangeo-data-private>,
<Bucket: zarr_store_test>]
Now I am trying to do the same thing from gcsfs. I get an error invalid_scope: Empty or missing scope not allowed
.

I am using the latest gcsfs master, installed from pip + git.
when checking on bucket existence, I get
ValueError: Bad Request: b/
Unknown project id: 0
Issue is actually with _list_buckets()
and the get
call to list buckets. The API requires the pass the project ID, not the project name - see https://cloud.google.com/storage/docs/json_api/v1/buckets/list and https://cloud.google.com/storage/docs/projects
BTW, that ID is also required to create a bucket so mkdir()
has same issue
This was not spotted before if you happened to have project name = ID
I would like to set up GCSFuse in a docker container pointing to a read-only public bucket. This container will not have any Google authentication by default. Is it possible to create a GCSFileSystem
without associating it to a google account and without using token='cloud'
?
I have a file of 30M lines and know that each line is max 2000 bytes long.
So if I want to iterate through the "file" (blob), I can specify the length of bytes to fetch to limit waste but doing that 3M times would cost huge latency.
I wonder if it would not be better - through an option - to read and cache a full block and read the lines from there.
This can be done outside of GCSFS but thought it may be embedded.
Opening as a tracking issue for follow-up discussed #58. I will be able to follow-up on this issue the week of 2018-01-28. From that thread:
[Testing #58] on a GCE instance I use as a dev box. On this machine I've the compute sdk installed and I'm I'm using the service account for application default credentials:
fordas@salish:~/distributed_dev/gcsfs$ gcloud auth list
Credentialed Accounts
ACTIVE ACCOUNT
* [email protected]
In this context auth2client.client.GoogleCredentials.get_application_default
returns an token component that manages access to the service credentials and does not include a refresh_token
, client_secret
. It instead provides access tokens via the get_access_token
interface, which handles token expiration and refresh. It may also be used to retrieve auth headers for requests.
This currently breaks the current master
implementation, which expects a refresh token to be available. This will also break this implementation.
After setting application default credentials to a user account via gcloud auth application-default login
auth2client.client.GoogleCredentials.get_application_default
returns a GoogleCredentials
object exposing refresh_token
et al. This credentials object is capable of handling access token and auth header generation.
Given that behavior, my current recommendation would be to hold the credential object returned by the get_application_default
and use the interface credential.get_access_token().access_token
to manage access. gcsfs
would then not be responsible for managing auth token management and refresh. It would also be desirable to wrap the device credentials generated via the browser
auth mode in a the same oauth handler and remove the token management logic currently implemented in gcsfs
.
In a broader sense, I would suggest emphasizing use of the default app credentials instead of obtaining and directly caching a credential object for gcsfs
. In "off cloud" contexts, the user can then manage authorization via the gcloud auth application-default
command, which provides login
, revoke
. In "on cloud" this then provides easy access to the default service account, with the option for a user to override this setting by gcloud auth login
.
I am trying to use gcsfs with a GCS service account .json token. I created a token at https://console.cloud.google.com/iam-admin/serviceaccounts/ and assigned it the role of "Storage Admin". This should have permissions to do anything to my GCS resources. I downloaded the .json token.
I use this with gcsfs as follows:
fs = gcsfs.GCSFileSystem(project='pangeo-181919', token='/home/rpa/pangeo-bf62fe06ed97.json')
fs.buckets
I get this error:

Unrelated but I also get a warning No module named dask.bytes.core
gcsfs
propagates an google.auth.exceptions.RefreshError
when executing many concurrent requests from a single node using the google_default
credentials class. This is likely due to repeated, excessive number of requests to the internal metadata service. This is a known bug of the external library at googleapis/google-auth-library-python#211.
Anecdotally, I've primarily observed this in dask.distributed
workers and believe this might occur due to the way GCSFiles are distributed. This primarily occurs when a large number of small files are being read from storage and many worker threads are performing concurrent reads. I believe the GCSFile
s serialized in dask tasks then each instantiate a separate GCSFilesystem
, resolve credentials and open a session.
If this is the case it would be preferable to store a fixed set of AuthenticatedSession
handles, ideally via cache on the GCSFilesystem
class, and dispatch to an auth-method-specific session in the GCSFilesystem._connect_*
connection functions.
As a more specific solution, google.auth.exceptions.RefreshError
or its base class should be added to the retrying exception list in _call, however this may mask legitimate authentication errors. The credentials should probably be "tested" via some call that does not retry this error during session initialization. This may be as simple as calling session.credentials.refresh
or performing a single authenticated request after session initialization.
In anonymous mode, or when accessing a bucket not included in our project, it will not appear in the buckets list (or, indeed, listing buckets may not be possible). In this case, exists()
on a bucket should instead attempt to list the bucket and return True if that succeeds.
I'm trying to read a publicly readable bucket using the GCSMap
. My account doesn't have much in the way of permissions, but the bucket is publicly readable.

This can be nice when the other side is relatively fast

It's not clear yet how effective this will be in practice.
We should release soon, but I think I would like to include batch-delete first (#69). Any other critical things that should be done?
Original discussion here
Quick summary: When reading a single file from a bucket containing a very large number of files, the read time can be very long before gcsfs downloads the list of all the files in the bucket. For a bucket with over 4 million files, this can take up to 15 minutes.
Suggested fix (easy): Check if the object path contains a wildcard. If it does not, then just download file. If it does, then proceed to download list of files.
Suggested fix (hard, not sure how to do yet, suggested by @martindurant ): implement prefix/delimiter listing, i.e., make it possible to use wildcard in object path (.e.g., bag.read_text('gs://mybucket/2017/01/*.csv')
) without having to download list of files from entire bucket.
Although there is no batch delete as such, there is such a concept as batch request in GCS: https://cloud.google.com/storage/docs/json_api/v1/how-tos/batch
I am trying to use gcsfs on a new system. I am invoking it as follows

From the outside it looks like sometimes GCS has some sort of transient errors and GCSFS ought to be able to survive those and retry.
Perhaps by default or with a recursive= keyword
I am trying to use gcsfs to access gcs from the NASA pleaides supercomputer.
I tried to initialize a gcsfs.mapping before having my credentials set up properly (although I thought my default credentials were valid.)
I was able to get past this error by setting GOOGLE_APPLICATION_CREDENTIALS
environment variable as described in the google cloud storage docs.
However, the info I got from gcsfs was now very helpful.

Suggestion/request to have a glob option to traverse the full tree e.g.
GCSFS.glob('bucket/**/*.[gz|zip]', recursive=true)
to list all matching files regardless of where located. This mimics glob in Python 3.6.
Workaround I can think of is to use walk() or ls() then regex
Feature request (or current workaround)
dict
parameter at file creation (open
in w
mode)I am trying to use gcsfs via distributed in pangeo-data/pangeo#150. I have uncovered what seems like a serialization bug.
This works from my notebook (the token appears to be cached):
fs = gcsfs.GCSFileSystem(project='pangeo-181919')
fs.buckets
It returns the four buckets: ['pangeo', 'pangeo-data', 'pangeo-data-private', 'zarr_store_test']
.
Now I create a distributed cluster and client and use it to run the same command:
from dask.distributed import Client, LocalCluster
cluster = LocalCluster(processes=False)
client = Client(cluster)
client.run(lambda : fs.buckets)
I get the following error:

When bucket in passed path does not exists, GSCFile fails on close (or when buffer is flushed), with a generic error like
Exception KeyError: ('location',) in <bound method GCSFile.__del__ of <GCSFile new_bucket/test>> ignored
GSCFile.__init__
should check on bucket existence and either create (preferred) or explicitly error out e.g. Bucket xxx does not exist
First option preferred to minimize pre-processing but requires parameters for storage class
& location
. Although could be defined as defaults.
Btw - do not use paranthesis in folder name, you cannot browse it in Google Console
(bug reported)
Google returns ValueError: Only 'authorized_user' tokens accepted, got: service_account
. Limitation or can that be extended ?
Note: @martindurant this is yet another great lib !! G only implemented cloudstorage
for their GAE Standard. File-like objects are perfect to minimize memory usage and skip the need for disk.
I have a bucket with several directories, each of which has thousands of files. When querying one of the directories that has 3600 files a call to fs.ls("bucket/my-dir")
takes several minutes. I actually don't know how long it takes since I've never let it finish. In contrast, the google client takes 3.4 seconds to return the directory listing [f for f in bucket.list_blobs(prefix='my-dir')]
(the comprehension is to force iteration over the iterator object they return).
It would be valuable to support the standard Text I/O interface in gcsfs for use as a standalone, file-like library. The current behavior requires binary IO, which is not directly compatible with some standard tools (eg. json
).
For example:
import json
import gcsfs
fs = gcsfs.GCSFileSystem(...)
an_obj = {"foo" : "bar"}
with fs.open("bucket/path", "w") as of:
json.dump(an_obj, of)
raises NotImplementedError
.
While it's possible to workaround via io.TextIOWrapper
, it would be best to expose a GCSFile
in text-mode in order to provide support for gcsfs-specific api extensions on the file object.
import json
import gcsfs
fs = gcsfs.GCSFileSystem(...)
an_obj = {"foo" : "bar"}
with fs.open("bucket/path", "wb') as of:
json.dump(an_obj, io.TextIOWrapper(of))
The following causes both terminals to hang in such a way that they can not be interrupted
$ pip install gcsfs --upgrade
$ mkdir gcs
$ gcsfuse pangeo-data gcs
Mounting bucket pangeo-data to directory gcs
$ ls gcs
I'm seeing intermittent errors using gcsfs==0.3.0
in a dask.distributed
cluster that, I believe, are due to an error in credential resolution. Briefly, when writing a large number of partitions to gcs via the dask.bag.to_textfiles
interface, a number of work partitions failed with the log message:
Enter the following code when prompted in the browser:
....

raise RuntimeError("Waited too long for browser"
RuntimeError: Waited too long for browserauthentication.
However a number of the work partitions completed successfully. This occured while using multithreaded workers, so I assume that some race condition in token retrieval triggered the browser-based authentication flow. Modifying the filesystem interface in dask.bytes.core
appeared to resolve the issue:
import dask.bytes
import gcsfs
import functools
org_fs = dask.bytes.core._filesystems['gcs']
wrapped_fs = functools.partial(org_fs, token="cloud")
dask.bytes.core._filesystems['gs'] = wrapped_fs
dask.bytes.core._filesystems['gcs'] = wrapped_fs
Credential resolution in the default case (i.e. GCSFileSystem(token=None)
) should resolve credentials from the default service account, rather than falling back to the oauth device flow, if the internal metadata service is available. I'm not familiar with the oauth2client.client.GoogleCredential.get_application_default() interface currently used in The master
, but if that interface queries instance metadata by default then this is a "doc bug" to clarify this behavior in the gcsfs interface.oauth2client.GoogleCredential.get_application_default
interface appears to provide a token for the GCE Service account when invoked on a GCE instance and does not profive the "refresh_token" expected by gcsfs
's token refresh logic. This poison's gcsfs
's token cache and blocks authorization if token=None
mode is used from a GCE
instance.
Pending the behavior clarification above, it seems strange to me that dask
would invoke gcsfs
in a mode that could require interactive authorization. I believe gcsfs
should support a headless
authorization mode which resolves credentials from (a) the ~/.gcs_tokens
token cache (b) the gcloud
application default credentials and (c) instance metadata, but provides an informative error if interactive oauth would be required, then register this mode (rather than the current token=None
mode) with dask.
This would allows users to authenticate manually via the current token=None
mode, then utilize the cached token for all further access.
Sorry for logging another one !
This one seems related to the cached credentials.

I wonder if increasing the block size to say 50MB would not reduce the likehood of these error (overload, 'corrupted' credentials,...)
Some operations do not seems to show updated file information on the next query - apparently the out-of-date is being incorrectly kept around.
I am trying to create a new GCSFileSystem with the command
fs = gcsfs.GCSFileSystem(project='pangeo-181919', token=None)
This triggers my browser to open and I have to enter the code. But I can never seem to finish it fast enough before I get the following error:
