paws.common 0.8.7

CRAN release: 2025-11-25

fix timezone handling in bearer token tests (#955). Thanks to @kyleam for raising issue.

paws.common 0.8.6

CRAN release: 2025-11-19

fix default json scalar from standard '"%s"' and use R classes to determine json parsing.
support httr2:::StreamingBody class
add support for bearer token authentication for AWS services (e.g., Bedrock). Bearer tokens can be provided via environment variables AWS_BEARER_TOKEN (generic) or AWS_BEARER_TOKEN_<SERVICE> (service-specific, e.g., AWS_BEARER_TOKEN_BEDROCK). Optional expiration can be set via AWS_BEARER_TOKEN_EXPIRATION. When available, bearer authentication is automatically used instead of AWS Signature V4 for supported services, following RFC 6750 Section 2.1 (#952). Thanks to @benhmin for raising issue.

)
#> Error: SerializationError (HTTP 304). failed to read from query HTTP response body

# new error message format

Fix timestamps in the S3 API, e.g. LastModified from get_object.

paws.common 0.3.14

CRAN release: 2021-10-24

Skip tests for issue network request function to avoid CRAN check errors.

paws.common 0.3.13

CRAN release: 2021-10-12

Support AWS_DEFAULT_REGION in addition to AWS_REGION.
Support calling SDK operations within do.call, including any user-supplied configuration to the service, e.g. a custom endpoint.

paws.common 0.3.12

CRAN release: 2021-08-15

Support S3 access points in all S3 operations that accept a bucket argument. Fixes #403.
Fix certain API requests for S3 that were malformed due to mistakenly including empty list elements, e.g. s3_put_bucket_lifecycle_configuration. Fixes #438.
Add an option to immediately close all HTTP connections, instead of the default behavior which will reuse connections for requests within 5 seconds. Using this feature allows you to switch credentials within 5 seconds without getting your request rejected with a SignatureDoesNotMatch error. Example usage: s3 <- paws::s3(config = list(close_connection = TRUE)). Fixes #431.

paws.common 0.3.11

CRAN release: 2021-05-20

Fix parsing of shared configuration and credential files.

paws.common 0.3.10

CRAN release: 2021-05-15

Use path style URLs for S3 when using custom endpoints, (e.g. localhost:9000/mybucket). This is useful when using software like MinIO. When not using custom endpoints, Paws will in general use “virtual hosted” URLs (e.g. mybucket.s3.amazonaws.com) except in special cases.
Use path style URLs for S3 when using the new s3_force_path_style option when calling paws::s3(), e.g.:
```
s3 <- paws::s3(config = list(
    s3_force_path_style = TRUE
))
```
Add support and a default value for timeout, how long to wait in seconds for an acknowledgement of an HTTP request before failing. Default = 60. This is user configurable by adding arguments to the service call, e.g.
```
svc <- paws::svc(config = list(timeout = 10))
```
Don’t skip lower case field names for REST location elements. For example, lexmodelbuildingservice$create_bot_version(name, checksum) previously failed due incorrectly skipping the name field.

paws.common 0.3.9

CRAN release: 2021-02-26

Support multifactor authentication, using the mfa_serial shared configuration file item.
Support AWS_CONFIG_FILE, AWS_SHARED_CREDENTIALS_FILE, AWS_CREDENTIAL_EXPIRATION, and AWS_EC2_METADATA_DISABLED environment variables. See https://github.com/paws-r/paws/blob/main/docs/credentials.md for explanations of all settings.
Cache credentials in each service object.

paws.common 0.3.8

CRAN release: 2021-01-25

Use no timeout by default when making HTTP requests. The previous release set the default timeout to 10 seconds, which prevented users from downloading large files.

paws.common 0.3.7

CRAN release: 2021-01-18

s3$put_object will now read in files when given file paths for the Body parameter. Previously it would accept only blobs, e.g. from readBin.

paws.common 0.3.6

CRAN release: 2020-12-05

Add the error response and HTTP status code to the condition object, in addition to having it be in the condition object’s attributes. This is in response to a request in issue #329.
Make errors be of class paws_error in addition to their other classes, e.g. http_400, error, condition.
Correctly unmarshal EC2 API error responses.

paws.common 0.3.5

CRAN release: 2020-10-25

Support getting AWS credentials from IAM roles using shared configuration file items role_arn, credential_source, and source_profile.
Support getting AWS credentials from running a process using shared configuration file item credential_process.
Fix decoding of errors from the EC2 API.

paws.common 0.3.4

CRAN release: 2020-09-06

Support S3 object keys with spaces.
Support writing empty S3 objects.
Support integers larger than 2^31 - 1 in API responses, e.g. S3 object size, by using 64-bit numeric objects rather than 32-bit integer objects.

paws.common 0.3.3

CRAN release: 2020-07-19

Decode base64-encoded blobs to raw vectors. Previously, Paws decoded them to UTF-8 inappropriately, which would fail for any data other than text.
In some cases, httr/curl do not decompress the response body. In these cases, check whether it looks compressed and try decompressing it.

paws.common 0.3.2

CRAN release: 2020-06-22

Support the S3 operation SelectObjectContent in s3$select_object_content. This operation allows you to query a data file in S3 using SQL.
Correctly decode Unicode strings in API responses received from AWS, such as "Me voy a casa mañana.".

paws.common 0.3.1

CRAN release: 2020-04-26

Read in session tokens from shared credential files.
Fix handling of dates when used as arguments to CloudWatch and other APIs. Previously the operation would submit the date in an inappropriate format.
Fix handling of profiles when specified for a specific service, e.g. paws::svc(config = list(credentials = list(profile = "my-profile"))). Previously the profile was not used to get credentials.
Fix handling of operations that return nothing – return an empty object rather than failing.

paws.common 0.3.0

CRAN release: 2020-03-28

Add HTTP status codes to the error response when an operation fails, along with any other information returned by AWS about the error.
Add support for S3 operation GetBucketLocation, which needs special handling.
Fix how paws.common provides request handlers to specific services (e.g. S3) so that fixes to handlers don’t require re-installing any package other than paws.common.

paws.common 0.2.6

CRAN release: 2020-02-23

Fix handling of nested inputs and outputs for services like DynamoDB.
Fix handling of output elements that are delivered in HTTP headers for REST-based services like S3.

CRAN release: 2019-10-19

paws.common 0.2.3

CRAN release: 2019-10-15

Fix support for non-default profiles in shared config files.

paws.common 0.2.2

CRAN release: 2019-10-03

Escape URIs, e.g. when uploading files to S3 with non-alphanumeric keys.
Fix XML request handling (e.g. used by S3) to correctly support requests with skipped optional arguments.

paws.common 0.2.1

CRAN release: 2019-09-21

Support session tokens stored in the AWS_SESSION_TOKEN environment variable.

paws.common 0.2.0

CRAN release: 2019-08-20

Use the global signing region (us-east-1) for services with global endpoints, e.g. IAM. This requires an updated list of endpoints in the arguments to new_service, namely each endpoint should look like list(endpoint = "foo", global = FALSE).

paws.common 0.1.2

CRAN release: 2019-08-08

Fix the EC2 IAM role credential provider.

paws.common 0.1.1

CRAN release: 2019-03-19

Add service customizations into paws.common to work with services like DynamoDB and S3 that require non-standard request handling.

paws.common 0.1.0

CRAN release: 2019-03-13

Initial release.
