aws.s3 0.3.22x

• get_bucket_df no longer throws an error when listing bucket contents from a Backblaze S3 bucket. Fixes #407.

aws.s3 0.3.22

API changes

• put_object splits the use of files vs payload into two separate arguments: what is now the first positional argument and expects actual content to store, file is now a named argument used to store file content. The previous use of file for both was very dangerous as it stored filenames instead of content without warning if the file was not found.

  Old code that intended to use files such as:

  put_object("foo.csv", "bucket")

  has to use either of

  put_object(file="foo.csv", bucket="bucket")
  ## or (not recommended)
  put_object(, "bucket", file="foo.csv")

  Any code that used file= explicitly and no positional arguments doesn't need to change.

Features

• put_object supports connections, including non-seekable ones

Bugfixes

• put_object now closes its connections properly (#354)

aws.s3 0.3.21

• s3HTTP() (and thus all API functions) gain write_fn=function(x) {...} argument which allows chunk-wise streaming output for GET requests.
• Replace sprintf() where possible to avoid type mismatches. (#329)
• Handle result of length one in bucketlist() correctly. (#333)
• Setting region="" and custom base_url enables the use of single-host non-AWS back-ends (e.g., minio). (#340)
• s3read_using() now cleans up after itself. (#270) It also gains a new argument filename which allows to specify the actual name of the file that will be used. (#341)
• Avoid invalid scientific notation in content sizes. (#299, h/t Martijn Schuemie)
• s3sync has been re-factored to work on directories instead of file lists. Please read the documentation, the arguments have changed. The previous version has never really worked for any other cases than sync of the working directory. Addresses many s3sync() issues including #346.

aws.s3 0.3.20

• Add acl and header arguments to put_acl(), ala put_object(). (#137)
• Make sure content-length is an integer (#254)

aws.s3 0.3.19

aws.s3 0.3.18

• Allowed both virtual- and path-style URLs for S3-compatible storage and fixed region handling for S3-compatible URLs. (#189)
• Fixed a request signature bug in put_bucket() when region = "us-east-1". (#243)

aws.s3 0.3.17

• Added s3connection() function to stream objects from S3. (#217)

aws.s3 0.3.16

• Refactored put_object(multipart = TRUE) to improve memory efficiency. (h/t Andrii Degtiarov, #242)
• Added provisional support for S3 SELECT via the select_object() function. (#224)

aws.s3 0.3.14

aws.s3 0.3.13

• s3HTTP() gains a show_progress logical argument specifying whether to print a progress bar for PUT, POST, and GET requests. (#235, h/t R. Roebuck)
• head_object() now simply returns as a logical without an extraneous class.
• New function object_size() provides a convenient wrapper around the "content-length" attribute of head_object(). (#234, h/t P. Roebuck)
• object_exists() is now implemented as a synonym for head_object() (#234, h/t P. Roebuck)

aws.s3 0.3.12

• s3write_using() now attaches the correct file extension to the temporary file being written to (just as s3read_using() already did). (#226, h/t @jon-mago)

aws.s3 0.3.11

• s3sync() gains a direction argument allowing for unidirectional (upload-only or download-only) synchronization. The default remains bi-directional.
• New functions put_encryption(), get_encryption(), and delete_encryption() implement bucket-level encryption so that encryption does not need to be specified for each put_object() call. (#183, h/t Dan Tenenbaum)
• Fixed typos in s3sync(). (#211, h/t Nirmal Patel)
• put_bucket() only includes a LocationConstraint body when the region != "us-east-1". (#171, h/t David Griswold)

aws.s3 0.3.10

• Fixed a typo in setup_s3_url(). (#223, h/t Peter Foley)
• Signatures are now calculated correctly when a port is specified. (#221, h/t @rvolykh)

• Bumped aws.signature dependency to v0.3.7 to take advantage of automatic credential loading. (#184, h/t Dan Tenenbaum)
• acl argument was ignored by put_bucket(). This is now fixed. (#172)
• The base_url argument in s3HTTP() now defaults to an environment variable - AWS_S3_ENDPOINT - or the AWS S3 default in order to facilitate using the package with S3-compatible storage. (#189, #191, #194)

aws.s3 0.3.8

• save_object() now uses httr::write_disk() to avoid having to load a file into memory. (#158, h/t Arturo Saco)

aws.s3 0.3.7

• Remove usage of endsWith() in two places to reduce (implicit) base R dependency. (#147, h/t Huang Pan)

aws.s3 0.2.2

• Two new functions - s3read_using() and s3write_using() provide a generic interface to reading and writing objects from S3 using a specified function. This provides a simple and extensible interface for the import and export of objects (such as data frames) in formats other than those provided by base R. (#125, #99)

aws.s3 0.2.1

• s3HTTP() gains a url_style argument to control use of "path"-style (new default) versus "virtual"-style URL paths. (#23, #118)

aws.s3 0.2.0

• All functions now produce errors when requests fail rather than returning an object of class "aws_error". (#86)

aws.s3 0.1.39

• s3save() gains an envir argument. (#115)

aws.s3 0.1.38

• get_bucket() now automatically handles pagination based upon the specified number of objects to return. (PR #104, h/t Thierry Onkelinx)
• get_bucket_df() now uses an available (but unexported) as.data.frame.s3_bucket() method. The resulting data frame always returns character rather than factor columns.

aws.s3 0.1.37

• Further changes to region vertification in s3HTTP(). (#46, #106 h/t John Ramey)

aws.s3 0.1.36

• bucketlist() now returns (in addition to past behavior of printing) a data frame of buckets.
• New function get_bucket_df() returns a data frame of bucket contents. get_bucket() continues to return a list. (#102, h/t Dean Attali)

aws.s3 0.1.35

• s3HTTP() gains a check_region argument (default is TRUE). If TRUE, attempts are made to verify the bucket's region before performing the operation in order to avoid confusing out-of-region errors. (#46)
• Object keys can now be expressed using "S3URI" syntax, e.g., object = "s3://bucket_name/object_key". In all cases, the bucketname and object key will be extracted from this string (meaning that a bucket does not need to be explicitly specified). (#100; h/t John Ramey)
• Fixed several places where query arguments were incorrectly being passed to the API as object key names, producing errors.

aws.s3 0.1.34

• Update and rename policy-related functions.

aws.s3 0.1.33

• Exported the get_bucket() S3 generic and methods.

aws.s3 0.1.32

• Fixed a bug related to the handling of object keys that contained spaces. (#84, #85; h/t Bao Nguyen)

aws.s3 0.1.29

• Fixed a bug related to the handling of object keys that contained atypical characters (e.g., =). (#64)
• Added a new function s3save_image() to save an entire workspace.
• Added a temporary fix for GitHub installation using the DESCRIPTION Remotes field.

aws.s3 0.1.25

• Added function s3source() as a convenience function to source an R script directly from S3. (#54)

aws.s3 0.1.23

• Added support for S3 "Acceleration" endpoints, enabling faster cross-region file transfers. (#52)
• s3save(), s3load(), s3saveRDS(), and s3readRDS() no longer write to disk, improving performance. (#51)

aws.s3 0.1.22

• Added new functions s3saveRDS() and s3readRDS(). (h/t Steven Akins, #50)

aws.s3 0.1.21

• Operations on non-default buckets (outside "us-east-1") now infer bucket region from bucket object. Some internals were simplified to better handle this. (h/t Tyler Hunt, #47)

aws.s3 0.1.18

• All functions now use snake case (e.g., get_object()). Previously available functions that did not conform to this format have been deprecated. They continue to work, but issue a warning. (#28)
• Separated authenticated and unauthenticated testthat tests, conditional on presence of AWS keys.
• Numerous documentation fixes and consolidations.
• Dropped XML dependency in favor of xml2. (#40)

aws.s3 0.1.17

• The structure of an object of class "s3_bucket" has changed. It now is simply a list of objects of class "s3_object" and bucket attributes are stored as attributes to the list.
• The order of bucket and object names was swapped in most object-related functions and the Bucket name has been added to the object lists returned by getbucket(). This means that bucket can be omitted when object is an object of class "s3_object".

aws.s3 0.1.1

• Initial release.
