Sync more than one source directory into a single bucket/prefix (#25)
* [changelog] updated

* [readme] updated

* [core] ConfigQuery added sources()

* [cli] ParseArgs allow specifying multiple sources

* [domain,core,cli] Source datatype changed to Path

* [domain] Sources added to hold multiple paths in order

* [domain] Config sources change datatype to Sources

* [core] Scan sources for .thorp.config and include any sources listed

This allows the inclusion of a `.thorp.config` file in a source with a
single line `source = ....` that causes that other source to also be
synched into the same remote prefix as the current source.

* [core] ConfigurationBuilderTest add more pending tests

* [[core] ConfigurationBuilderTest rewrite using loan-pattern for fixtures

* [core] ConfigOptionTest use TemporaryFolder

* [core] ConfigOptionTest remove unused fields

* [cli] ParseArgsTest don't use get on an Option

* [core] ConfigurationBuilderTest don't use get on Either

* [core] TemporaryFolder Move import to top of file

* [core] TemporaryFolder use Try over try-finally

* [core] ConfigurationBuilderTest don't use get on Either

* [core] TemporaryFolders.withDirectory propogate errors

* [core] TemporaryFolders add writeFile and createFile

* [core] PlanBuilderTest create a plan with two sources with unique files in both

* [core] ActionGenerator only upload file by name in first source

create a plan
  two sources
    same filename in both
    - only upload file in first source

* [domain] LastModified with no params is now()

* [core] PlanBuilderTest 2 sources w/remote only in 2nd src do nothing

* [core] PlanBuilderTest 2 sources w/remote only in 2nd src do nothing

* [domain] RemoteKey map to a file when prefix is empty

* [domain] S3ObjectData defaults to empty

* [core] KeyGenerator Avoid delimiter when empty prefix key

* [core] PlanBuilderTest when remote not in sources delete from remote

* [core] PlanBuilderTest extract helper md5Hash()

* [core] PlanBuilderTest one source a file no matching remote key

* [core] PlanBuildingTest file with matching key and hash do nothing

* [core] PlanBuilderTest file w/matching remote key and different hash

* [core] PlanBuilderTest a remote key with and without local file

* [core] DummyStorageService Use wildcards when selecting more than 6 elements

thorp

Synchronisation of files with S3 using the hash of the file contents.

Originally based on Alex Kudlick's aws-s3-sync-by-hash.

The normal aws s3 sync ... command only uses the time stamp of files to decide what files need to be copied. This utility looks at the md5 hash of the file contents.

Usage

  thorp
  Usage: thorp [options]

    -V, --version         Display the version and quit
    -B, --batch           Enabled batch-mode
    -s, --source <value>  Source directory to sync to S3
    -b, --bucket <value>  S3 bucket name
    -p, --prefix <value>  Prefix within the S3 Bucket
    -i, --include <value> Include matching paths
    -x, --exclude <value> Exclude matching paths
    -d, --debug           Enable debug logging
    --no-global           Ignore global configuration
    --no-user             Ignore user configuration

If you don't provide a source the current diretory will be used.

The --include and --exclude parameters can be used more than once.

The --source parameter can be used more than once, in which case, all files in all sources will be consolidated into the same bucket/prefix.

Batch mode

Batch mode disable the ANSI console display and logs simple messages that can be written to a file.

Configuration

Configuration will be read from these files:

  • Global: /etc/thorp.conf
  • User: ~ /.config/thorp.conf
  • Source: ${source}/.thorp.conf

Command line arguments override those in Source, which override those in User, which override those Global, which override any built-in config.

When there is more than one source, only the first ".thorp.conf" file found will be used.

Built-in config consists of using the current working directory as the source.

Note, that include and exclude are cumulative across all configuration files.

Behaviour

When considering a local file, the following table governs what should happen:

# local file remote key hash of same key hash of other keys action
1 exists exists matches - do nothing
2 exists is missing - matches copy from other key
3 exists is missing - no matches upload
4 exists exists no match matches copy from other key
5 exists exists no match no matches upload
6 is missing exists - - delete

Executable JAR

To build as an executable jar, perform `sbt assembly`

This will create the file `cli/target/scala-2.12/thorp`

Copy this file to your `PATH`.
