gsutil

New Features

• Added support for socks proxies, including socks4 and socks5.

Bug Fixes

• Fixed cp/mv errors that occur when destination directory is a substring of another directory. Behavior now more closely matches OS cp/mv commands.
• Fixed issue where set IAM policy on objects threw errors.
• Fixed issue when showing help in a pager in Python 3 environments.

Other Changes

• Several documentation updates and clarifications.

Bug Fixes

• Fixed some text encoding/decoding issues in certain Python 3 environments.
• Fixed issue where bundled crcmod for macOS could not be imported and would crash gsutil on Python 3.
• Fixed issue where trying to run gsutil on an unsupported version of Python 3 (3.4 or below) would crash instead of presenting an informative error.

Other Changes

• Several documentation updates and clarifications.

New Features

• Added HMAC key management for service accounts. This includes a new "hmac" command to create/get/list/update/delete HMAC keys on service accounts. Currently, your project must be added to the allowlist for use with this new HMAC functionality. This restriction will be lifted in the near future.

Bug Fixes

• Fixed bug where copying files > 100MiB from GCS to S3 was hanging.
• Fixed issue where content type was sometimes set improperly.

New Features

• Added support for running gsutil on Python 3.5+. Python 2 will reach its EOL (End of Life) on Jan. 1, 2020, and gsutil will stop supporting Python 2.7 at some point afterward (TBD).

Bug Fixes

• Fixed bug introduced in v4.39 where rsync would not correctly sync object/file names containing some special URL-encodable characters (e.g. "+" and whitespace characters).
• Fixed the update command so that it no longer fails when it detects the presence of additional top-level files that were added in the v4.39 release.

Other Changes

• Several documentation updates and clarifications.

New Features

• Compression level is now configurable by setting "gzip_compression_level" under the "GSUtil" section in the boto config file. The default value is 9.

Bug Fixes

• Fixed bug where IAM operations failed on buckets whose names lacked any letters.

Other Changes

• Revised contribution guidelines to direct developers to submit GitHub pull requests instead of using the Rietveld code review tool.
• Several code changes to work toward Python 3 support (coming in a subsequent release).
• Several documentation and command help improvements.
• Various improvements to test stability and feedback.

Bug Fixes

• Fixed issue where multiprocessing check would raise an exception if /etc/os-release was not in the expected format.

Other Changes

• Improved error message for trying to retrieve default object ACLs on a bucket with Bucket Policy Only enabled.
• When running "gsutil -D rsync ..." and encountering an error listing local files, gsutil will now print a stack trace as debug-level output.
• Several documentation updates and clarifications.

Bug Fixes

• Fixed a bug where XML API requests would sometimes fail with SSLError exceptions due to SNI not being used for https connections.
• Fixed "du" output spacing for 6-digit sizes.

Other Changes

• Updated crcmod installation instructions for CentOS 6.

New features

• Added Bucket Policy Only support to gsutil. This includes a new "bucketpolicyonly" command to get/set BPO on existing buckets, as well adding the ability to set BPO at bucket creation time with "mb -b". Currently, your project must be added to the allowlist for use with the new BPO functionality. This restriction will be lifted in the near future.

Bug Fixes

• Fixed a bug where "cp -n" would overwrite a local file at the destination if its size differed from the source's size.

Other Changes

• Updated crcmod installation instructions for enterprise SUSE systems.

New features

• Added -u option to rsync; this will skip copying files/objects that are newer (as determined by checking mtime) at the destination.

Bug Fixes

• The "iam ch" command now allows supplying custom IAM roles.
• Fixed an issue where debug output was not displaying all of the loaded config files under the "config path(s)" label.
• Disabled running with multiple processes when running on Alpine Linux, as this would sometimes cause gsutil to hang forever. Running with multiple threads is still allowed.
• The "rsync" command now prints log messages during synchronization to indicate when symlinks are being skipped.
• The "Boto:ca_certificates_file" config option can now be overridden using the -o option.

Other Changes

• Disallowed installing gsutil on Python versions != 2.7.
• Several documentation updates and clarifications.

New features

• Added bucket lock support to gsutil. Currently, your project must be added to the allowlist for use with the new bucket lock functionality. This restriction will be lifted in the near future.

Bug Fixes

• Fixed issue where "rsync -P" would fail if run as the root user.
• Fixed an issue with credential caching where the source credentials for an entity would change but the old cached credentials would still be used.

Other Changes

• OAuth2 token exchanges now go to https://oauth2.googleapis.com/token instead of https://accounts.google.com/o/oauth2/token. Users using gsutil behind a firewall may need to adjust their firewall rules.
• If invoked via the Cloud SDK, gsutil's debug output now displays the path to gcloud's gsutil wrapper script for "gsutil path", rather than the actual entry point for the bundled gsutil component.
• Improved error messages for failed Cloud KMS requests.
• Improved error messages for "iam ch" command to clarify that assigning roles to project convenience groups (e.g. "projectEditor") is not allowed.
• Enhanced perfdiag command to include GCE instance details (if applicable) and the target bucket's location and storage class.
• Several documentation updates and clarifications.

Bug Fixes

• Fixed an issue with the "rsync" command on Windows that would cause gsutil to incorrectly join file path segments when the source given was the root of a drive, e.g. "C:".
• Fixed several places where gsutil referenced a variable that had not been correctly imported.

Other Changes

• Several documentation updates and clarifications.

Bug Fixes

• Fixed a file path resolution issue on Windows that affected local-to-cloud copy-based operations ("cp", "mv", "rsync"). If a local file URI containing relative path components ("." or "..") or forward slashes (rather than backslashes) was provided as a source argument, the resulting destination object(s) was incorrectly named. For recursive operations, this resulted in several files being copied to the same object path, overwriting each other.
• Fixed an issue with the "rsync" command on Windows that resulted in each rsync invocation not being able to delete its temporary synchronization files on disk.
• Fixed an issue where reading a specific generation of an object from S3 would fail.
• Fixed an issue where running gsutil with the top-level "-q" flag would result in credential-related logging statements being emitted to stderr.
• Gsutil no longer allows copying from streamed input if the top-level "-m" flag is specified. While this was previously allowed, it did not work correctly.

Other Changes

• Several documentation updates and clarifications.

New features

• Added support for reauthentication within gsutil. Note that this only affects authentication when "gs_oauth2_refresh_token" is configured under the "Credentials" section of the boto config file and that token corresponds to a user account enrolled in 2-step verification.

Bug Fixes

• When creating a signed URL via the "signurl" command, gsutil now verifies that the specified expiration isn't longer than 7 days (the maximum allowed by the service).
• To support rewriting objects to be encrypted using a bucket's default KMS key, the "rewrite" command now rewrites all specified objects if no value is specified for "encryption_key" under the "GSUtil" section in the boto config file.

Other Changes

• Several documentation updates and clarifications.

New features

• Added Cloud KMS support for Google Cloud Storage resources, allowing the use of customer-managed encryption keys (CMEKs). Bucket-related functionality includes the new "kms" command, which can be used to get or set a bucket's default KMS key. Concerning objects, users may now specify the CMEK to be used for encryption via their boto config file, in the "encryption_key" attribute. In this way, users may specify either a CSEK or a CMEK to encrypt new objects, but not both. For more information, see "gsutil help encryption".

Other Changes

• Several documentation updates and clarifications.

New features

• Added transport compression support, available through the "-j" and "-J" options for the "cp", "mv", and "rsync" commands. This is useful when uploading files with highly-compressible content. When specificed, files being uploaded are compressed on-the-fly in memory, sent to GCS, and uncompressed by GCS before they are stored. See "gsutil help cp" for additional information.
• When "use_magicfile=True" is set in the boto config file, gsutil will now append the detected charset, if present, to the object's Content-Type metadata field. For example, a Content-Type might be populated with "text/html; charset=us-ascii" rather than simply "text/html".

Bug Fixes

• Improved error handling and logging for upload resumption.
• After encountering a PreconditionException, the "acl ch" command will now re-fetch the object generation before retrying.
• Fixed issue with parsing lifecycle conditions when using the XML API. Conditions whose values could be evaluated by Python as "falsy" (e.g. setting an "age" condition to the number 0 or "isLive" to false) would be omitted from the lifecycle configuration when "prefer_api=xml" was set in the boto config file. Note that the JSON API is preferred by default, so most users were unlikely to encounter this issue.
• For commands that fetch bucket ACLs or default ACLs, when the user does not have storage.buckets.getIamPolicy on the GCS bucket, using the XML API will now behave consistently with the JSON API and display ACL/default ACL fields as empty, rather than throwing a CommandException.

Other Changes

• Several documentation updates and clarifications.
• The "signurl" command now uses signature V4 signing format to generate URLs.

New features

• Added newest version of the Boto library, which includes support for using Signature Version 4 to connect to S3 buckets via the "use-sigv4 = True" and "host = s3.<region>.amazonaws.com" Boto options under the "[s3]" section.
• Added support for Requester Pays functionality when making requests to GCS buckets with this feature enabled. For example usage, see the entry for "-u" in "gsutil help options". Requester Pays is currently only supported for requests using the GCS JSON API; XML API support will be added in a later version.

Bug Fixes

• Fixed issue where attempting to preserve ACLs by using "-p" with cp/mv/rsync would fail when the destination is a local file.
• Improved quality of several ambiguous error messages.

Other Changes

• The proxy_rdns option is now True by default when a proxy is set. Also added Boto config file comments explaining that gcloud proxy options, if present, take precedence over corresponding Boto settings and environment variable settings.
• Following the deprecation of Python 2.6 support for gsutil, code sections that were only present to support Python 2.6 have been removed.
• Several documentation updates and clarifications.

New features

• When using the JSON API, the "ls -L" and "stat" commands now print an object's storage class update time if it differs from the object's creation time; this occurs when the storage class has been changed due to the bucket's lifecycle management configuration.
• Listing a bucket's metadata via "ls -Lb" now prints its metageneration.

Bug Fixes

• When specifying custom metadata values using the top-level -h option, such values may now include unicode characters as well as multiple ":" characters.
• For Cloud SDK (gcloud) distributions of gsutil, if you have configured the Cloud SDK to not pass credentials to gsutil (by running "gcloud config set pass_credentials_to_gsutil false"), gsutil will now correctly work with credentials obtained via "gsutil config". This would previously result in an error with a message to run "gcloud auth login". Additionally, the "gsutil config" command no longer prompts users to run "gcloud auth login" if this option is set to false. This should allow switching between stand-alone gsutil installations and gcloud-packaged gsutil installations more easily.
• The config_file_list section in debug output now displays files in the order that they are loaded.

Other Changes

• Added XML support for some commands which previously only worked via the JSON API ("lifecycle" and "defstorageclass").
• Several documentation updates and clarifications.

New features

• The cp command now supports reading from and writing to named pipes.

Bug Fixes

• Fixed issue where tab completion wasn't working.
• Fixed issue when using the XML API where gsutil would fail to parse bucket metadata for buckets using Lifecycle rules containing the SetStorageClass action or MatchesStorageClass condition.

Other Changes

• Removed -o flag from "notification create" command. The same functionality is available with the -p flag; the -o flag had been mistakenly added in a previous change.
• Removed the alpha disclaimer from the iam command help text.
• Several documentation updates and clarifications.

New features

• Added bucket label support to gsutil. For more details, see https://cloud.google.com/compute/docs/label-or-tag-resources.
• Added the label command, which can be used to get, set, and change the labels for an existing bucket (known as "tags" for S3 buckets).
• Listing a bucket via "gsutil ls -Lb" now also displays the labels, if any exist, that are currently set on it.

New Features

• Added support for configuring GCS Cloud Pub/Sub notifications. For more details, see https://cloud.google.com/storage/docs/pubsub-notifications.
• Added support for specifying canned ACLs when using the rsync command.

Bug Fixes

• Fixed a bug where error messages about invalid object names did not correctly display the problematic object name.

Bug Fixes

• Fixed "referenced before assignment" error in some copy_helper exceptions for resumable uploads and non-resumable cloud-to-local downloads.
• The setmeta command now properly supports case sensitivity in custom metadata keys when using the JSON API.
• Fixed a resource leak affecting Windows in cases where single-process, multithreaded parallelism is used that would result in an OSError with the message "Too many open files".
• Fixed HTTPError initialization failure in signurl command.
• Fixed signurl issue where attempting to validate short-lived URLs on a slow connection would fail because of URL expiration.
• Fixed a bug where cp -r would not properly resolve wildcards for cloud-to-cloud copies.
• Fixed a bug where cp -e -r would copy symlinks.
• Fixed a bug where cp -P would fail on Windows.
• Fixed a bug where version -l might not show all boto configuration files.
• Running perfdiag now only lists the objects that were created by that run of perfdiag. This fixes an issue where running perfdiag against an existing bucket with many objects in it could take a long time.

Other Changes

• Simplified parallelism when using a single process with multiple threads. With this change, gsutil will spawn a new thread pool per level of parallelism. As an example, if you specify that you want a parellel_thread_count of 24, this will result in 24 worker threads, except when you're using parallel composite uploads or sliced downloads, in which case 48 (24 * 2) worker threads will be used.
• Extended the early deletion warning threshold when moving Coldline objects to 90 days after object creation.
• Improved several error messages and warnings.
• Several documentation updates and clarifications.

New features

• Added per-object storage class functionality to gsutil. For more details, see https://cloud.google.com/storage/docs/per-object-storage-class.
• Added the defstorageclass command, which can be used to get and set an existing bucket's default storage class.
• The cp, mv, and rewrite commands now support the "-s" option, allowing users to specify the storage class for destination object(s). When no storage class is specified, the object's storage class will be assigned from either its bucket's default storage class (cp/mv commands) or the source object's storage class (rewrite command).

Bug Fixes

• Fixed a bug in POSIX preservation for the cp and mv commands where POSIX attributes were not propagated to cloud objects, even when the -P flag was present.
• Fixed a bug in setmeta where removing custom metadata would add an empty-string value if the key did not already exist.
• Content-Type is now obtained from symlink targets, rather than symlinks themselves, when the use_magicfile option is set in the .boto configuration file.

Other Changes

• Analytics reporting now includes performance metrics such as average throughput and thread idle time.
• The iam set command now supports a -e option to specify an etag precondition check. The IAM policy file returned by iam get and used by iam set has also been altered to include this field.
• Default limit for max number of processes changed to 64.
• Several documentation updates and clarifications.

New Features

• The console output for many commands has been improved to display command progress.
• The cp, mv, and rsync commands now support a -P option that preserves POSIX file attributes from the source. Currently, mode, gid, uid, atime, and mtime attributes are supported for uploads, downloads, and copies.
• gsutil can now optionally report anonymous usage statistics that help gsutil developers improve the tool. For non-gcloud distributions, prompts have been added to the config and update commands. Prompts can be disabled via the disable_analytics_prompt value in the .boto configuration file.
• Added the iam commmand, which can be used to set IAM policies on Google Cloud Storage buckets and objects. This feature is currently in alpha and requires a safelist application to use it - see "gsutil help iam" for details.
• The hash command now supports retrieving hashes for cloud objects.

Bug Fixes

• Fixed a bug where rsync -e -r could fail for subdirectories with broken symlinks.
• Fixed an access error when interacting with S3 user-specific directories.

Other Changes

• Updated boto library dependency to 2.42.0.

New Features

• gsutil now outputs a message that estimates the total number of objects for commands affecting more than 30,000 objects. This value can be adjusted via task_estimation_threshold in the .boto configuration file.

Bug Fixes

• Fixed a bug in resumable downloads that could raise UnboundLocalError if the download file was not readable.
• Updated oauth2client to version 2.2.0, fixing some IOError and OSError cases.
• Fixed bug in gsutil ls that would show update time instead of creation time when using the JSON API and -L or -l flags.
• Fixed a bug in gsutil rsync -d that could cause erroneous removal of an extra destination object.
• Fixed downloads to include accept-encoding:gzip logic when appropriate.

Other Changes

• gsutil rsync now stores modification time (mtime) for cloud objects.
• Changed the default change detection algorithm of gsutil rsync from file size to file mtime, falling back to checksum and finally file size as alternatives. This allows for increased accuracy of rsync without the speed sacrifice that comes from checksum calculation, and makes gsutil rsync work more similarly to how Linux rsync works. Note that the first run of a local-to-cloud rsync using this new algorithm may be slower than subsequent runs, as the cloud objects will not initially have an mtime, and the algorithm will fall back to the slower checksum-based alternative in addition to adding mtime to the cloud objects.
• When using the JSON API, gsutil will output a progress message before retrying a request if enough time has passed since the first attempt.
• Improved error detection in dry runs of gsutil rsync by attempting to open files that would be copied.
• Added time created and time updated properties to output of gsutil ls -Lb.
• Added archived time property to output of gsutil ls -La and gsutil stat.
• Changed minimum number of source objects for gsutil compose from 2 to 1.
• Removed an HTTP metadata get call from cp, acl, and setmeta commands. This improves the speed of gsutil cp for small objects by over 50%.
• Several documentation updates and clarifications.

Deprecation Notice

• gsutil support for Python 2.6 is deprecated, and gsutil will stop supporting Python 2.6 on September 1, 2016. This change is being made for two reasons. First, Python 2.6 stopped receiving security patches since October 2013. Second, removing Python 2.6 support will enable gsutil to add support for Python 3. Versions of gsutil released prior to September 1, 2016 will continue to work with Python 2.6. However, bug fixes will not be made retroactively to older gsutil versions, and users reporting bugs will be asked to upgrade to the current gsutil version (using Python 2.7, or, when it is supported, Python 3).

Other Changes

• Improved documentation around Cloud SDK (gcloud) installs.

New Features

• gsutil now supports the beta Customer-Supplied Encryption Keys features for Google Cloud Storage objects, via the JSON API. This feature allows you to encrypt your data with keys that are not permanently stored on Google's servers. You can provide encryption and decryption keys in your .boto configuration file. As long as an encryption key is specified in the configuration file, all gs:// objects that gsutil creates will be stored encrypted with that key, and all encrypted objects will be decrypted when downloaded. See "gsutil help csek" for more information.
• Added the rewrite command, which can be used to perform key rotation for objects encrypted with customer-supplied encryption keys.

Bug Fixes

• Fixed an AttributeError that could occur when running in debug mode for operations involving wildcards, recursion, or listing.
• Fixed an ArgumentException that could occur when using perfdiag write throughput tests with parallelism.
• Restored debug mode output for resumable uploads using the JSON API.
• Fixed a bug where rm -r on a bucket subdirectory would exit with code 1 even though it succeeded.
• Fixed a bug where cp -R of a single file with a destination other than the bucket root would copy to the bucket root.
• Fixed a bug when using a single process with multiple threads where CTRL-C would not stop the process until one thread completed a task.

Other Changes

• Improved exception logging in debug mode.
• Added "cache-control: no-transform" to all uploads using compression ("gsutil cp -z" or "gsutil cp -Z") to ensure that doubly-compressed objects can be downloaded with data integrity checking.
• Reduced the default number of threads per-process on Linux systems from 10 to 5.
• Documented additional OS X Unicode limitations.
• The config command now includes the custom client ID and secret in the configuration file output if the command is run with those values configured.

Bug Fixes

• Fixed an oauth2client dependency break that caused the PyPi distribution of gsutil to allow oauth2client 2.0.0, causing all commands to fail with an ImportError.
• Fixed a bug where gsutil could leak multiprocessing.Manager processes when terminating signals (such as CTRL-C) were sent.
• Fixed a bug where the -q option did not suppress output from the stat command.
• Fixed a bug where deleting an empty bucket with rm -r would return a non-zero exit code even when successful.
• Fixed UnicodeEncodeErrors that could occur when using the du command with a pipe on objects containing non-ASCII characters.

Other Changes

• Many documentation improvements and clarifications.

New Features

• The ls command now supports a -d option (similar to Unix ls -d) for suppressing recursion into subdirectories.
• The signurl command now accepts JSON-format private key files generated by the Google Developers Console.
• The signurl command now supports generating resumable upload start URLs.
• The cp command now supports a -Z option which will gzip-compress all files (regardless of their extensions) as they are uploaded.

Bug Fixes

• Fixed a bug where an expired OAuth2 token could include the OAuth2 token response as part of the download, causing it to fail end-to-end integrity checks and be deleted.
• Fixed a bug where streaming downloads using the JSON API would restart from the beginning of the stream if the connection broke. This bug could also cause data corruption in streaming downloads, because streaming downloads are not validated with end-to-end integrity checks.
• Fixed an internal_failure exception that could occur when an OAuth2 token refresh returned a transient error, such as an HTTP 503.
• Fixed a resource deadlock exception in oauth2client that could cause sliced downloads to hang.
• Fixed a bug where cp/rsync -p would use the default object ACL for the destination object if the caller did not have OWNER permission on the source object.
• Fixed a potential race condition when using perfdiag with multiple threads and/or processes.
• Fixed an AttributeError that could occur when using acl ch -p.
• Fixed a bug where the mv command did not properly handle the global -m flag.
• Fixed a UnicodeEncodeError that could occur when iterating over non-Unicode-named directories.
• Fixed a bug where an object name including a wildcard could cause an infinite loop during a recursive listing.
• Fixed a Unicode bug when using cp or ls on Windows on an object containing certain Unicode characters. However, even with this fix Unicode can still be problematic on Windows; consult "gsutil help encoding" for details.
• Fixed a Windows performance issue during rsync diff generation.
• Fixed a bug in the ordering of ls output.
• Fixed a bug where Windows help output included ANSI escape codes.
• Fixed a compatibility bug with perfdiag -i with input generated prior to gsutil 4.14.

Other Changes

• Several documentation updates, including rsync exclusion pattern matching, service account configuration, cp/rsync recursion flags, multi-object rm, versioned URL removal, destination subdirectory naming, wildcard behavior, regional buckets, and s3 connection reset.
• Improvements to Unicode documentation including LANG variable and iconv tool.

Bug Fixes

• Fixed an OverflowError in apitools that caused download failures for large files on 32-bit machines.
• Removed unnecessary sending of range headers for downloads when using the XML API.
• Fixed a bug that caused perfdiag to report extremely high throughput when the -p flag was unspecified and exactly one of the -c or -k flags were specified.
• Fixed a ValueError that occurred on Python 2.6 with sliced object downloads.

Other Changes

• HTTP connections for downloads and uploads in the JSON API are now re-used per-thread.
• When gsutil's automatic update feature prompts and the user chooses to update, gsutil will now exit with status code 1 after updating (because the original command was not executed).
• The cp -A flag is disabled when using gsutil -m to ensure that ordering is preserved when copying between versioned buckets.

New Features

• Implemented Sliced Object Download feature. This breaks up a single large object into multiple pieces and downloads them in parallel, improving performance. The gsutil cp, mv and rsync commands now use this by default when compiled crcmod is available for performing fast end-to-end integrity checks. If compiled crcmod is not available, normal object download will be used. Sliced download can be used in conjunction with the global -m flag for maximum performance to download multiple objects in parallel while additionally slicing each object. See the "SLICED OBJECT DOWNLOAD" section of "gsutil help cp" for details. Note: sliced download may cause performance degradation for disks with very slow seek times. You can disable this feature by setting sliced_object_download_threshold = 0 in your .boto configuration file.
• Added rthru_file and wthru_file test modes to perfdiag, allowing measurement of reads and writes from a disk. This also allows measurement of transferring objects too large to fit in memory. The size restriction of 20GiB has been lifted.
• perfdiag now supports a -p flag to choose a parallelism strategy (slice, fan, or both) when using multiple threads and/or processes.

Bug Fixes

• Fixed an IOError that could occur in apitools when acquiring credentials using multiple threads and/or processes on Google Compute Engine.
• Fixed a bug where rm -r would attempt to delete a nonexistent bucket.
• Fixed a bug where a default object ACL could not be set or changed to empty.
• Fixed a bug where cached credentials corresponding to an old account could be used (for example, credentials associated with a prior .boto configuration file).
• Fixed a bug in apitools for retrieving byte ranges of size 1 (for example, "cat -r 1-1 ...")
• Fixed a bug that caused the main gsutil process to perform all work leaving all gsutil child processes idle.
• Fixed a bug that caused multiple threads not to be used when multiprocessing was unavailable.
• Fixed a bug that caused rsync to skip files that start with "." when the -r option was not used.
• Fixed a bug that caused rsync -C to bail out when it failed to read a source file.
• Fixed a bug where gsutil stat printed unwanted output to stderr.
• Fixed a bug where a parallel composite upload could return a nonzero exit code even though the upload completed successfully. This occurred if temporary component deletion triggered a retry but the original request succeeded.
• Fixed a bug where gsutil would exit with code 0 when both running in debug mode and encountering an unhandled exception.
• Fixed a bug where gsutil would suggest using parallel composite uploads multiple times.

Other Changes

• Bucket removal is now supported even if billing is disabled for that bucket.
• Refactored Windows installs to no longer use any multiprocessing module functions, as gsutil has never supported multiple processes on Windows. Multithreading is unaffected and still available on Windows.
• All downloads are now written to a temporary file with a "_.gstmp" suffix while the download is still in progress.
• Re-hashing of existing bytes when resuming downloads now displays progress.
• Reduced the total number of multiprocessing.Manager processes to two.
• The rm command now correctly counts the number of objects that could not be removed.
• Increased the default retries to match the Google Cloud Storage SLA. By default, gsutil will now retry 23 times with exponential backoff up to 32 seconds, for a total timespan of ~10 minutes.
• Improved bucket subdirectory checks to a single HTTP call. Detection of _$folder$ placeholder objects is now eventually consistent.
• Eliminated two unnecessary HTTP calls when performing uploads via the cp, mv, or rsync commands.
• Updated documentation for several topics including acl, cache-control, crcmod, cp, mb, rsync, and subdirs.
• Added a warning about using parallel composite upload with NEARLINE storage-class buckets.

New Features

• Added -U flag to cp and rsync commands to allow skipping of unsupported object types.
• Added support for Google Developer Shell credentials.

Bug Fixes

• Precondition headers (x-goog-if-...) are now respected for the setmeta command.
• Fixed an index out of range error that could occur with an empty parallel composite upload tracker file.
• The stat command outputs errors to stderr instead of stdout.
• Fixed two possible sources of ResumableUploadStartOverException from httplib2 and oauth2client.
• Fixed a bug in the compose command where a missing source object resulted in an error message claiming the destination object was missing.

Other Changes

• Added a help section on throttling gsutil.
• Resumable uploads will now start over if a PUT to the upload ID returns an HTTP 404. Previously this behavior applied only to an HTTP 410.
• XML API resumable uploads now retry on HTTP 429 errors, matching the behavior of JSON API resumable uploads.
• Improved response to process kill signals, reducing the likelihood of leaving orphaned child processes and temporary files.
• Bucket lifecycle configuration now works for S3.
• Removed the deprecated setmeta -n option.

New Features

• Added support for JSON-format service account private key files.
• Added support for the Rewrite API (JSON API only). This is used for all copies within the Google Cloud and supports copying objects across storage classes and/or locations.

Bug Fixes

• Fixed a bug that could cause downloads to have a hash mismatch (and deletion of the corrupted file) when resumed across process breaks via a tracker file.

Other Changes

• Updated documentation and examples for several topics including acl, cp, dev, signurl, stat, and wildcards.

New Features

• Added Nearline storage class support to the mb command.

Bug Fixes

• Fixed a bug for streaming uploads that could occasionally cause a HTTP 410 from the service or a hash mismatch (and deletion of the corrutped file).
• Fixed an OverflowError that occurred when uploading files > 4GiB on a 32-bit operating system.

Other Changes

• Added documentation around using the Content-MD5 header to extend integrity checking to include checksums computed by a client-side content pipeline.

Bug Fixes

• Fixed a bug that could cause undetected data corruption (preserving incorrect data) if a streaming upload encountered a service error on non-8KiB-aligned boundary.
• Fixed a bug that caused downloads to be truncated if the connection broke, resulting in a hash mismatch (and deletion of the corrupted file) for that download.
• Fixed a format string arguments error that occurred if a download exhausted all retries.

Other Changes

• The lifecycle command now accepts JSON input in the form of "{ "lifecycle": { "rule" ..." in addition to "{ "rule": ...".
• Improved access token expiry logic for GCE credentials.

New Features

• When using the JSON API, the ch acl/defacl subcommand now supports project groups via the -p flag. For details, see "gsutil help acl ch".

Bug Fixes

• Fixed a bug that caused daisy-chain copies (including cross-provider copies) for files large than 100MiB to fail.
• Fixed a bug that caused streaming uploads than ran for longer than an hour to fail with HTTP 400s.
• Fixed a bug where perfdiag would not properly clean up its test files.

• Non-wildcarded URLs for existing objects now use Get before trying List (as in gsutil3), and thus are not subject to eventual listing consistency.
• gsutil -D now redacts proxy configuration values in the output.

New Features

Bug Fixes

• Fix acl/defacl ch changing the role of an existing group.
• Fix unicode and 404 errors when using manifests.
• Fix parallelism configuration bug that limited gsutil rsync to two threads and could lead to rsync hangs. "gsutil -m rsync" runs much faster, and rsync uploads of large local files are now faster via parallel composite upload. Parallel composite uploads of large files are also faster.

Other Changes

• Parallel composite uploads no longer specify an if-not-match precondition when uploading component parts.
• Parallel composite uploads no longer calculate a CRC32c hash prior to uploading component parts (these are still validated by an MD5 hash).
• Removed apitools dependency on gflags.

Major New Gsutil Version - Backwards-Incompatible Changes

• The Google Cloud Storage configuration data supported by the acl, cors, and lifecycle commands now uses the JSON format instead of the older XML format. gsutil 4.0 will fail and provide conversion instructions if an XML configuration file is provided as an argument for a gs:// URL.
• gsutil no longer accepts arbitrary headers via the global -h flag. Documented headers for gsutil commands are still supported; for the full list of supported headers, see "gsutil help command_opts".
• The compose command will now default the destination object's Content-Type to the Content-Type of the first source object if none is provided via the -h global flag.
• The long-deprecated -t and -q options have been removed from the cp command.
• The perfdiag command no longer supports adding a host header.
• Having OAuth2 User Account credentials and OAuth2 Service Account credentials configured simultaneously will now fail with an error message to avoid confusion. Also, a single invalid credential will fail with an error message. See "gsutil help creds" for details.
• Bucket relocate scripts have been removed.
• Downloading object names ending with '/' is no longer supported to avoid problems this caused for directores using the Google Cloud Console.
• rm -r now implies rm -ra (removing all object versions recursively).
• All commands using the global -m option or a force option (such as rm -f or cp -c) will now return a non-zero exit code if there are any failures during the operation.
• MD5 and CRC32c values are now represented in base64 encoding instead of hex encoding (this includes manifest files).

New Features

• The Google Cloud Storage JSON API (v1) is now the default API used by gsutil for all commands targeting gs:// URLs. The JSON API is more bandwidth efficient than the older XML API when transferring metadata and does not require separate calls to preserve object ACLs when copying. The XML API will automatically be used when accessing s3:// URLs.
• The Google Cloud Storage XML API can be used in lieu of the JSON API by setting 'prefer_api = xml' in the GSUtil section of your boto config file.
• Added the rsync command that can synchronize cloud and local directories.
• Added the signurl command that can generate Google Cloud Storage signed URLs.
• The perfdiag command now supports a listing latency test.
• The rb command now supports a -f flag allowing it to continue when errors are encountered.
• The test command now supports a -s flag that runs tests against S3.

Other Changes

• All python files not under a third_party directory are now pylint-clean, with the exception of TODO-format and a handful of warnings in root-level files. As part of the de-linting process, many edge-case bugs were identified and fixed.
• The ls command now operates depth-first (as in Unix ls) instead of breadth-first.
• Daisy-chain copying does not currently support resumable uploads.
• Several compatibility improvements for Windows and S3.

Other Changes

• Fixed potential bug with update command on CentOS.

Other Changes

• Changes to protect security of resumable upload IDs.

Bug Fixes

• Added .git* to MANIFEST.in excludes and fixed cp doc typo. This was needed to overcome problem caused by accidental inclusion of .git* files in release, which caused the update command no longer to allow updates (since starting in 3.32 it checks whether the user has any extraneous files in the gsutil directory before updating)

New Features
