Changelog

Pre-released (Will be v0.6.0)

  • (Enhancement) Allow Arc to transform and store directly on binary input.
  • (Bugfix - backwards incompatible) Return error tuple rather than raising Arc.ConvertError if the transformation fails.
  • (Bugfix) Update :crypto usage to :crypto.strong_rand_bytes
  • (Enhancement) Optionally set S3 bucket from runtime env var (config :arc, bucket: {:system, "S3_BUCKET"})
  • (Enhancement) Temporary files created during transformations now include the file extension.
  • (Bugfix) Add a leading slash to urls generated from the Local storage adapter.

v0.5.3 (2016-06-21)

  • (Enhancement) Relax ex_aws dependency to allow ~> 0.5.0

v0.5.2 (2016-04-27)

  • (Enhancement) Allow returning a list of arguments for transformations to preserve desired groupings.

v0.5.1 (2016-03-02)

  • (Enhancement) Raise a more helpful error message when attempting a transformation with an executable which cannot be found.

v0.5.0 (2016-03-02)

  • (Enhancement) Allow transforms via arbitrary system executables.
  • (Enhancement) Allow transforms to supply a function to define the transformation args.
  • (Deprecation) Deprecate usage of {:noaction} in favor of :noaction for transformation responses.

Upgrade instructions from 0.4.x to 0.5.x:

Arc now favors explicitness in file extension changes rather than scanning with a Regex. If you have a convert transformation which changes the file extension (through the parameter -format png argument), you must explicitly add a third tuple argument in the conversion noting the final extension.

Example:

# Change this:
  def transform(:thumb, _) do
    {:convert, "-strip -thumbnail 250x250^ -gravity center -extent 250x250 -format png"}
  end

# To this:
  def transform(:thumb, _) do
    {:convert, "-strip -thumbnail 250x250^ -gravity center -extent 250x250 -format png", :png} #<--- Note the third tuple argument with the output file extension
  end

v0.4.1 (2016-02-28)

  • (Bugfix) Fix regression using the local filesystem introduced via v0.4.0.

v0.4.0 (2016-02-25)

  • (Bugfix) Surface errors from ExAws put operations. Parse ExAws errors and return tuple of form {:error, List.t} when an error is encountered.

To upgrade and properly support parsing aws errors, add :poison to your list of dependencies.

Optional dependency added, prompting a minor version bump. While not a strict backwards incompatibility, Arc users should take note of the change as more than an internal change.

v0.3.0 (2016-01-22)

  • (Enhancement) Introduce Definition.delete/2

While there is no strict backwards incompatibility with the public API, a number of users have been using Arc.Storage.S3.delete/3 as a public API due to a lack of a fully supported delete method. This internal method has now changed slightly, thus prompting more than a patch release.

v0.2.3 (2016-01-22)

  • (Enhancement) Allow specifying custom s3 object headers through the definition module via s3_object_headers/2.

v0.2.2 (12-14-2015)

  • (Enhancement) Allow the version transformation and storage timeout to be specified in configuration config :arc, version_timeout: 15_000.

v0.2.1 (12-11-2015)

  • (Bugfix) Raise Arc.ConvertError if ImageMagick's convert tool exits unsuccessfully.

v0.2.0 (12-11-2015)

  • (Breaking Change) Erlcloud has been removed in favor of ExAws.
  • (Enhancement) Added a configuration parameter to generate urls in the virtual_host style.

Upgrade Instructions

Since erlcloud has been removed from arc, you must also remove it from your dependency graph as well as your application list. In its place, add ex_aws and httpoison to your dependencies as well as application list. Next, remove the aws credential configuration from arc:

# BEFORE
config :arc,
  access_key_id: "###",		
  secret_access_key: "###",		
  bucket: "uploads"

#AFTER
config :arc,
  bucket: "uploads"

# (this is the default ex_aws config... if your keys are not in environment variables you can override it here)
config :ex_aws,
  access_key_id: [{:system, "AWS_ACCESS_KEY_ID"}, :instance_role],
  secret_access_key: [{:system, "AWS_SECRET_ACCESS_KEY"}, :instance_role]

v0.1.4 (11-10-2015)

  • (Enhancement: Local Storage) Filenames which contain path separators will flatten out as expected prior to moving copying the file to its destination.

v0.1.3 (09-15-2015)

  • (Enhancement: Url Generation) default_url/2 introduced to definition module which passes the given scope as the second parameter. Backwards compatibility is maintained for default_url/1.

v0.1.2 (09-08-2015)

  • (Bugfix: Storage) Bugfix for referencing atoms in the file name.

v0.1.1

  • (Enhancement: Storage) Add the local filesystem as a storage option.
