# NAME Amazon::S3 - A portable client library for working with and managing Amazon S3 buckets and keys. ![Amazon::S3](https://github.com/rlauer6/perl-amazon-s3/actions/workflows/build.yml/badge.svg?event=push) # SYNOPSIS use Amazon::S3; my $aws_access_key_id = "Fill me in!"; my $aws_secret_access_key = "Fill me in too!"; my $s3 = Amazon::S3->new( { aws_access_key_id => $aws_access_key_id, aws_secret_access_key => $aws_secret_access_key, retry => 1 } ); my $response = $s3->buckets; # create a bucket my $bucket_name = $aws_access_key_id .

This module is rather dated, however with some help from a few contributors it has had some recent updates. Recent changes include implementations of: - ListObjectsV2 - CopyObject - DeleteObjects Additionally, this module now implements Signature Version 4 signing, unit tests have been updated and more documentation has been added or corrected. Credentials are encrypted if you have encryption modules installed. ## Comparison to Other Perl S3 Modules Other implementations for accessing Amazon's S3 service include `Net::Amazon::S3` and the `Paws` project. `Amazon::S3` ostensibly was intended to be a drop-in replacement for `Net:Amazon::S3` that "traded some performance in return for portability". That statement is no longer accurate as `Amazon::S3` may have changed the interface in ways that might break your applications if you are relying on compatibility with `Net::Amazon::S3`. However, `Net::Amazon::S3` and `Paws::S3` today, are dependent on `Moose` which may in fact level the playing field in terms of performance penalties that may have been introduced by recent updates to `Amazon::S3`. Changes to `Amazon::S3` include the use of more Perl modules in lieu of raw Perl code to increase maintainability and stability as well as some refactoring. `Amazon::S3` also strives now to adhere to best practices as much as possible. `Paws::S3` may be a much more robust implementation of a Perl S3 interface, however this module may still appeal to those that favor simplicity of the interface and a lower number of dependencies. Below is the original description of the module. > Amazon S3 is storage for the Internet. It is designed to > make web-scale computing easier for developers. Amazon S3 > provides a simple web services interface that can be used to > store and retrieve any amount of data, at any time, from > anywhere on the web. It gives any developer access to the > same highly scalable, reliable, fast, inexpensive data > storage infrastructure that Amazon uses to run its own > global network of web sites. The service aims to maximize > benefits of scale and to pass those benefits on to > developers. > > To sign up for an Amazon Web Services account, required to > use this library and the S3 service, please visit the Amazon > Web Services web site at http://www.amazonaws.com/. > > You will be billed accordingly by Amazon when you use this > module and must be responsible for these costs. > > To learn more about Amazon's S3 service, please visit: > http://s3.amazonaws.com/. > > The need for this module arose from some work that needed > to work with S3 and would be distributed, installed and used > on many various environments where compiled dependencies may > not be an option. [Net::Amazon::S3](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3AS3) used [XML::LibXML](https://metacpan.org/pod/XML%3A%3ALibXML) > tying it to that specific and often difficult to install > option. In order to remove this potential barrier to entry, > this module is forked and then modified to use [XML::SAX](https://metacpan.org/pod/XML%3A%3ASAX) > via [XML::Simple](https://metacpan.org/pod/XML%3A%3ASimple). # LIMITATIONS AND DIFFERENCES WITH EARLIER VERSIONS As noted, this module is no longer a _drop-in_ replacement for `Net::Amazon::S3` and has limitations and differences that may impact the use of this module in your applications. Additionally, one of the original intents of this fork of `Net::Amazon::S3` was to reduce the number of dependencies and make it _easy to install_. Recent changes to this module have introduced new dependencies in order to improve the maintainability and provide additional features. Installing CPAN modules is never easy, especially when the dependencies of the dependencies are impossible to control and include XS modules. - MINIMUM PERL Technically, this module should run on versions 5.10 and above, however some of the dependencies may require higher versions of `perl` or some lower versions of the dependencies due to conflicts with other versions of dependencies...it's a crapshoot when dealing with older `perl` versions and CPAN modules. You may however, be able to build this module by installing older versions of those dependencies and take your chances that those older versions provide enough working features to support `Amazon::S3`. It is likely they do...and this module has recently been tested on version 5.10.0 `perl` using some older CPAN modules to resolve dependency issues. To build this module on an earlier version of `perl` you may need to downgrade some modules. In particular I have found this recipe to work for building and testing on 5.10.0. In this order install: HTML::HeadParser 2.14 LWP 6.13 Amazon::S3 ...other versions _may_ work...YMMV. - API Signing Making calls to AWS APIs requires that the calls be signed. Amazon has added a new signing method (Signature Version 4) to increase security around their APIs. This module no longer utilizes Signature Version V2. **New regions after January 30, 2014 will only support Signature Version 4.** See ["Signature Version V4"](#signature-version-v4) below for important details. - Signature Version 4 [https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html) _IMPORTANT NOTE:_ Unlike Signature Version 2, Version 4 requires a regional parameter. This implies that you need to supply the bucket's region when signing requests for any API call that involves a specific bucket. Starting with version 0.55 of this module, `Amazon::S3::Bucket` provides a new method (`region()`) and accepts in the constructor a `region` parameter. If a region is not supplied, the region for the bucket will be set to the region set in the `account` object (`Amazon::S3`) that you passed to the bucket's new constructor. Alternatively, you can request that the bucket's new constructor determine the bucket's region for you by calling the `get_location_constraint()` method. When signing API calls, the region for the specific bucket will be used. For calls that are not regional (`buckets()`, e.g.) the default region ('us-east-1') will be used. - Signature Version 2 [https://docs.aws.amazon.com/AmazonS3/latest/userguide/RESTAuthentication.html](https://docs.aws.amazon.com/AmazonS3/latest/userguide/RESTAuthentication.html) - New APIs This module does not support some of the newer API method calls for S3 added after the initial creation of this interface. - Multipart Upload Support There are some recently added unit tests for multipart uploads that seem to indicate this feature is working as expected. Please report any deviation from expected results if you are using those methods. For more information regarding multipart uploads visit the link below. [https://docs.aws.amazon.com/AmazonS3/latest/API/API\_CreateMultipartUpload.html](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html) # METHODS AND SUBROUTINES ## new Create a new S3 client object. Takes some arguments: - credentials (optional) Reference to a class (like `Amazon::Credentials`) that can provide credentials via the methods: get_aws_access_key_id() get_aws_secret_access_key() get_token() If you do not provide a credential class you must provide the keys when you instantiate the object. See below. _You are strongly encourage to use a class that provides getters. If you choose to provide your credentials to this class then they will be stored in this object. If you dump the class you will likely expose those credentials._ - aws\_access\_key\_id Use your Access Key ID as the value of the AWSAccessKeyId parameter in requests you send to Amazon Web Services (when required). Your Access Key ID identifies you as the party responsible for the request. - aws\_secret\_access\_key Since your Access Key ID is not encrypted in requests to AWS, it could be discovered and used by anyone. Services that are not free require you to provide additional information, a request signature, to verify that a request containing your unique Access Key ID could only have come from you. **DO NOT INCLUDE THIS IN SCRIPTS OR APPLICATIONS YOU DISTRIBUTE. YOU'LL BE SORRY.** _Consider using a credential class as described above to provide credentials, otherwise this class will store your credentials for signing the requests. If you dump this object to logs your credentials could be discovered._ - token An optional temporary token that will be inserted in the request along with your access and secret key. A token is used in conjunction with temporary credentials when your EC2 instance has assumed a role and you've scraped the temporary credentials from _http://169.254.169.254/latest/meta-data/iam/security-credentials_ - secure Set this to a true value if you want to use SSL-encrypted connections when connecting to S3. Starting in version 0.49, the default is true. default: true - timeout Defines the time, in seconds, your script should wait or a response before bailing. default: 30s - retry Enables or disables the library to retry upon errors. This uses exponential backoff with retries after 1, 2, 4, 8, 16, 32 seconds, as recommended by Amazon. default: off - host Defines the S3 host endpoint to use. default: s3.amazonaws.com Note that requests are made to domain buckets when possible. You can prevent that behavior if either the bucket name does not conform to DNS bucket naming conventions or you preface the bucket name with '/'. If you set a region then the host name will be modified accordingly if it is an Amazon endpoint. - region The AWS region you where your bucket is located. default: us-east-1 - buffer\_size The default buffer size when reading or writing files. default: 4096 ## signer Sets or retrieves the signer object. API calls must be signed using your AWS credentials. By default, starting with version 0.54 the module will use [Net::Amazon::Signature::V4](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3ASignature%3A%3AV4) as the signer and instantiate a signer object in the constructor. Note however, that signers need your credentials and they _will_ get stored by that class, making them susceptible to inadvertant exfiltration. You have a few options here: - 1. Use your own signer. You may have noticed that you can also provide your own credentials object forcing this module to use your object for retrieving credentials. Likewise, you can use your own signer so that this module's signer never sees or stores those credentials. - 2. Pass the credentials object and set `cache_signer` to a false value. If you pass a credentials object and set `cache_signer` to a false value, the module will use the credentials object to retrieve credentials and create a new signer each time an API call is made that requires signing. This prevents your credentials from being stored inside of the signer class. _Note that using your own credentials object that stores your credentials in plaintext is also going to expose your credentials when someone dumps the class._ - 3. Pass credentials, set `cache_signer` to a false value. Unfortunately, while this will prevent [Net::Amazon::Signature::V4](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3ASignature%3A%3AV4) from hanging on to your credentials, you credentials will be stored in the `Amazon::S3` object. Starting with version 0.55 of this module, if you have installed [Crypt::CBC](https://metacpan.org/pod/Crypt%3A%3ACBC) and [Crypt::Blowfish](https://metacpan.org/pod/Crypt%3A%3ABlowfish), your credentials will be encrypted using a random key created when the class is instantiated. While this is more secure than leaving them in plaintext, if the key is discovered (the key however is not stored in the object's hash) and the object is dumped, your _encrypted_ credentials can be exposed. - 4. Use very granular credentials for bucket access only. Use credentials that only allow access to a bucket or portions of a bucket required for your application. This will at least limit the _blast radius_ of any potential security breach. - 5. Do nothing...send the credentials, use the default signer. In this case, both the `Amazon::S3` class and the [Net::Amazon::Signature::V4](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3ASignature%3A%3AV4) have your credentials. Caveat Emptor. See also [Amazon::Credentials](https://metacpan.org/pod/Amazon%3A%3ACredentials) for more information about safely storing your credentials and preventing exfiltration. ## region Sets the region for the API calls. This will also be the default when instantiating the bucket object unless you pass the region parameter in the `bucket` method or use the `verify_region` flag that will _always_ verify the region of the bucket using the `get_location_constraint` method. default: us-east-1 ## buckets buckets([verify-region]) - verify-region (optional) `verify-region` is a boolean value that indicates if the bucket's region should be verified when the bucket object is instantiated. If set to true, this method will call the `bucket` method with `verify_region` set to true causing the constructor to call the `get_location_constraint` for each bucket to set the bucket's region. This will cause a significant decrease in the peformance of the `buckets()` method. Setting the region for each bucket is necessary since API operations on buckets require the region of the bucket when signing API requests. If all of your buckets are in the same region and you have passed a region parameter to your S3 object, then that region will be used when calling the constructor of your bucket objects. default: false Returns a reference to a hash containing the metadata for all of the buckets owned by the accout or (see below) or `undef` on error. - owner\_id The owner ID of the bucket's owner. - owner\_display\_name The name of the owner account. - buckets An array of [Amazon::S3::Bucket](https://metacpan.org/pod/Amazon%3A%3AS3%3A%3ABucket) objects for the account. Returns `undef` if there are not buckets or an error occurs. ## add\_bucket add_bucket(bucket-configuration) `bucket-configuration` is a reference to a hash with bucket configuration parameters. - bucket The name of the bucket. See [Bucket name rules](https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html) for more details on bucket naming rules. - acl\_short (optional) See the set\_acl subroutine for documenation on the acl\_short options - location\_constraint - region The region the bucket is to be created in. Returns a [Amazon::S3::Bucket](https://metacpan.org/pod/Amazon%3A%3AS3%3A%3ABucket) object on success or `undef` on failure. ## bucket bucket(bucket, [region]) bucket({ bucket => bucket-name, verify_region => boolean, region => region }); Takes a scalar argument or refernce to a hash of arguments. You can pass the region or set `verify_region` indicating that you want the bucket constructor to detemine the bucket region. If you do not pass the region or set the `verify_region` value, the region will be set to the default region set in your `Amazon::S3` object. See [Amazon::S3::Bucket](https://metacpan.org/pod/Amazon%3A%3AS3%3A%3ABucket) for a complete description of the `bucket` method. ## delete\_bucket Takes either a [Amazon::S3::Bucket](https://metacpan.org/pod/Amazon%3A%3AS3%3A%3ABucket) object or a reference to a hash containing: - bucket The name of the bucket to remove - region Region the bucket is located in. If not provided, the method will determine the bucket's region by calling `get_bucket_location`. Returns a boolean indicating the success or failure of the API call. Check `err` or `errstr` for error messages. Note from the [Amazon's documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/BucketRestrictions.html) > If a bucket is empty, you can delete it. After a bucket is deleted, > the name becomes available for reuse. However, after you delete the > bucket, you might not be able to reuse the name for various reasons. > > For example, when you delete the bucket and the name becomes available > for reuse, another AWS account might create a bucket with that > name. In addition, **some time might pass before you can reuse the name > of a deleted bucket**. If you want to use the same bucket name, we > recommend that you don't delete the bucket. ## dns\_bucket\_names Set or get a boolean that indicates whether to use DNS bucket names. default: true ## list\_bucket, list\_bucket\_v2 List all keys in this bucket. Takes a reference to a hash of arguments: - bucket (required) The name of the bucket you want to list keys on. - prefix Restricts the response to only contain results that begin with the specified prefix. If you omit this optional argument, the value of prefix for your query will be the empty string. In other words, the results will be not be restricted by prefix. - delimiter If this optional, Unicode string parameter is included with your request, then keys that contain the same string between the prefix and the first occurrence of the delimiter will be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. For example, with prefix="USA/" and delimiter="/", the matching keys "USA/Oregon/Salem" and "USA/Oregon/Portland" would be summarized in the response as a single "USA/Oregon" element in the CommonPrefixes collection. If an otherwise matching key does not contain the delimiter after the prefix, it appears in the Contents collection. Each element in the CommonPrefixes collection counts as one against the MaxKeys limit. The rolled-up keys represented by each CommonPrefixes element do not. If the Delimiter parameter is not present in your request, keys in the result set will not be rolled-up and neither the CommonPrefixes collection nor the NextMarker element will be present in the response. NOTE: CommonPrefixes isn't currently supported by Amazon::S3. - max-keys This optional argument limits the number of results returned in response to your query. Amazon S3 will return no more than this number of results, but possibly less. Even if max-keys is not specified, Amazon S3 will limit the number of results in the response. Check the IsTruncated flag to see if your results are incomplete. If so, use the Marker parameter to request the next page of results. For the purpose of counting max-keys, a 'result' is either a key in the 'Contents' collection, or a delimited prefix in the 'CommonPrefixes' collection. So for delimiter requests, max-keys limits the total number of list results, not just the number of keys. - marker This optional parameter enables pagination of large result sets. `marker` specifies where in the result set to resume listing. It restricts the response to only contain results that occur alphabetically after the value of marker. To retrieve the next page of results, use the last key from the current page of results as the marker in your next request. See also `next_marker`, below. If `marker` is omitted,the first page of results is returned. Returns `undef` on error and a reference to a hash of data on success: The return value looks like this: { bucket => $bucket_name, prefix => $bucket_prefix, marker => $bucket_marker, next_marker => $bucket_next_available_marker, max_keys => $bucket_max_keys, is_truncated => $bucket_is_truncated_boolean keys => [$key1,$key2,...] } - is\_truncated Boolean flag that indicates whether or not all results of your query were returned in this response. If your results were truncated, you can make a follow-up paginated request using the Marker parameter to retrieve the rest of the results. - next\_marker A convenience element, useful when paginating with delimiters. The value of `next_marker`, if present, is the largest (alphabetically) of all key names and all CommonPrefixes prefixes in the response. If the `is_truncated` flag is set, request the next page of results by setting `marker` to the value of `next_marker`. This element is only present in the response if the `delimiter` parameter was sent with the request. Each key is a reference to a hash that looks like this: { key => $key, last_modified => $last_mod_date, etag => $etag, # An MD5 sum of the stored content. size => $size, # Bytes storage_class => $storage_class # Doc? owner_id => $owner_id, owner_displayname => $owner_name } ## get\_bucket\_location get_bucket_location(bucket-name) get_bucket_locaiton(bucket-obj) This is a convenience routines for the `get_location_constraint()` of the bucket object. This method will return the default region of 'us-east-1' when `get_location_constraint()` returns a null value. my $region = $s3->get_bucket_location('my-bucket'); Starting with version 0.55, `Amazon::S3::Bucket` will call this `get_location_constraint()` to determine the region for the bucket. You can get the region for the bucket by using the `region()` method of the bucket object. my $bucket = $s3->bucket('my-bucket'); my $bucket_region = $bucket->region; ## get\_logger Returns the logger object. If you did not set a logger when you created the object then an instance of `Amazon::S3::Logger` is returned. You can log to STDERR using this logger. For example: $s3->get_logger->debug('this is a debug message'); $s3->get_logger->trace(sub { return Dumper([$response]) }); ## list\_bucket\_all, list\_bucket\_all\_v2 List all keys in this bucket without having to worry about 'marker'. This is a convenience method, but may make multiple requests to S3 under the hood. Takes the same arguments as `list_bucket`. _You are encouraged to use the newer `list_bucket_all_v2` method._ ## err The S3 error code for the last error encountered. ## errstr A human readable error string for the last error encountered. ## error The decoded XML string as a hash object of the last error. ## last\_response Returns the last [HTTP::Response](https://metacpan.org/pod/HTTP%3A%3AResponse) object. ## last\_request Returns the last [HTTP::Request](https://metacpan.org/pod/HTTP%3A%3ARequest) object. ## level Set the logging level. default: error ## turn\_on\_special\_retry Called to add extra retry codes if retry has been set ## turn\_off\_special\_retry Called to turn off special retry codes when we are deliberately triggering them # ABOUT This module contains code modified from Amazon that contains the following notice: # This software code is made available "AS IS" without warranties of any # kind.

And yes, testing counts as using. Because of this, the application's test suite skips anything approaching a real test unless you set these environment variables: For more on testing this module see [README-TESTING.md](https://github.com/rlauer6/perl-amazon-s3/blob/master/README-TESTING.md) - AMAZON\_S3\_EXPENSIVE\_TESTS Doesn't matter what you set it to. Just has to be set - AMAZON\_S3\_HOST Sets the host to use for the API service. default: s3.amazonaws.com Note that if this value is set, DNS bucket name usage will be disabled for testing. Most likely, if you set this variable, you are using a mocking service and your bucket names are probably not resolvable. You can override this behavior by setting `AWS_S3_DNS_BUCKET_NAMES` to any value. - AWS\_S3\_DSN\_BUCKET\_NAMES Set this to any value to override the default behavior of disabling DNS bucket names during testing. - AWS\_ACCESS\_KEY\_ID Your AWS access key - AWS\_SECRET\_ACCESS\_KEY Your AWS sekkr1t passkey. Be forewarned that setting this environment variable on a shared system might leak that information to another user. Be careful. - AMAZON\_S3\_SKIP\_ACL\_TESTS Doesn't matter what you set it to. Just has to be set if you want to skip ACLs tests. - AMAZON\_S3\_SKIP\_PERMISSIONS Skip tests that check for enforcement of ACLs...as of this version, LocalStack for example does not support enforcement of ACLs. - AMAZON\_S3\_SKIP\_REGION\_CONSTRAINT\_TEST Doesn't matter what you set it to. Just has to be set if you want to skip region constraint test. - AMAZON\_S3\_MINIO Doesn't matter what you set it to. Just has to be set if you want to skip tests that would fail on minio. - AMAZON\_S3\_LOCALSTACK Doesn't matter what you set it to. Just has to be set if you want to skip tests that would fail on LocalStack. - AMAZON\_S3\_REGIONS A comma delimited list of regions to use for testing. The default will only test creating a bucket in the local region. _Consider using an S3 mocking service like `minio` or `LocalStack` if you want to create real tests for your applications or this module._ Here's bash script for testing using LocalStack #!/bin/bash # -*- mode: sh; -*- BUCKET=net-amazon-s3-test-test ENDPOINT_URL=s3.localhost.localstack.cloud:4566 AMAZON_S3_EXPENSIVE_TESTS=1 \ AMAZON_S3_HOST=$ENDPOINT_URL \ AMAZON_S3_LOCALSTACK=1 \ AWS_ACCESS_KEY_ID=test \ AWS_ACCESS_SECRET_KEY=test \ AMAZON_S3_DOMAIN_BUCKET_NAMES=1 make test 2>&1 | tee test.log To run the tests...clone the project and build the software. cd src/main/perl ./test.localstack # ADDITIONAL INFORMATION ## LOGGING AND DEBUGGING Additional debugging information can be output to STDERR by setting the `level` option when you instantiate the `Amazon::S3` object. Levels are represented as a string. The valid levels are: fatal error warn info debug trace You can set an optionally pass in a logger that implements a subset of the `Log::Log4perl` interface. Your logger should support at least these method calls. If you do not supply a logger the default logger (`Amazon::S3::Logger`) will be used. get_logger() fatal() error() warn() info() debug() trace() level() At the `trace` level, every HTTP request and response will be output to STDERR. At the `debug` level information regarding the higher level methods will be output to STDERR. There currently is no additional information logged at lower levels. ## S3 LINKS OF INTEREST - [Bucket restrictions and limitations](https://docs.aws.amazon.com/AmazonS3/latest/userguide/BucketRestrictions.html) - [Bucket naming rules](https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html) - [Amazon S3 REST API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) - [Authenticating Requests (AWS Signature Version 4)](https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html) - [Authenticating Requests (AWS Signature Version 2)](https://docs.aws.amazon.com/AmazonS3/latest/userguide/RESTAuthentication.html) - [LocalStack](https://localstack.io) # SUPPORT Bugs should be reported via the CPAN bug tracker at [http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Amazon-S3](http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Amazon-S3) For other issues, contact the author. # REPOSITORY [https://github.com/rlauer6/perl-amazon-s3](https://github.com/rlauer6/perl-amazon-s3) # AUTHOR Original author: Timothy Appnel Current maintainer: Rob Lauer # SEE ALSO [Amazon::S3::Bucket](https://metacpan.org/pod/Amazon%3A%3AS3%3A%3ABucket), [Net::Amazon::S3](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3AS3) # COPYRIGHT AND LICENCE This module was initially based on [Net::Amazon::S3](https://metacpan.org/pod/Net%3A%3AAmazon%3A%3AS3) 0.41, by Leon Brocard.
