Rome

Rome is a tool that allows developers on Apple platforms to use:

• Amazon's S3
• Minio
• Ceph
• other S3 compatible object stores
• or/and a local folder
• your own custom engine

as a shared cache for frameworks built with Carthage.

Get Rome

Using Homebrew

$ brew tap tmspzz/tap https://github.com/tmspzz/homebrew-tap.git
$ brew install tmspzz/homebrew-tap/rome

Using CocoaPods

Simply add the following line to your Podfile:

pod 'Rome'

This will download Rome to the Pods/ folder during your next pod install execution and will allow you to invoke it via ${PODS_ROOT}/Rome/rome in your Script Build Phases.

Manual

The Rome binary is also attached as a zip to each release on the releases page here on GitHub.

Using Rome? Let me know by opening an issue and I will gladly add you to the user list.

Use Rome with fastlane

You can integrate Rome into your fastlane automation with the fastlane plugin for Rome.

The problem

Suppose you're working a number of frameworks for your project and want to share those with your team. A great way to do so is to use Carthage and have team members point the Cartfile to the new framework version (or branch, tag, commit) and run carthage update.

Unfortunately this will require them to build from scratch the new framework. This is particularly annoying if the dependency tree for that framework is big and / or takes a long time to build.

The solution

Use a cache. The first team member (or a CI) can build the framework and share it, while all other developers can get it from the cache with no waiting time.

Workflow

The Rome's workflow changes depending if you are the producer (i.e. the first person in your team to build the framework) or the consumer.

Producer workflow

$ vi Cartfile # point to the new version of the framework
$ carthage update && rome upload

If you are running Rome in the context of a framework and want to upload the current framework see CurrentMap.

Consumer workflow

$ vi Cartfile # point to the new version of the framework if necessary
$ carthage update --no-build && rome download

or

$ vi Cartfile.resolved # point to the new version of the framework
$ rome download

If you are running Rome in the context of a framework and want to download the current framework see CurrentMap.

CI workflow

A CI can be both consumer and producer.

A simple workflow for using Rome on a continuous integration should resemble the following:

• get available artifacts
• check if any artifacts are missing
• build missing artifacts if any
• upload build artifacts to the cache if needed

You can use the fastlane plugin for Rome to implement a CI workflow too.

If you are running Rome in the context of a framework and want to upload or download the current framework see CurrentMap.

--cache-builds workflow (recommended)

This workflow relies on .version files being produced by Carthage. This means that you have to invoke carthage with --cache-builds for this to work.

In code:

#!/bin/bash
rome download --platform iOS # download missing frameworks (or copy from local cache)
carthage bootstrap --platform iOS --cache-builds # build dependencies missing a .version file or that where not found in the cache
rome list --missing --platform iOS | awk '{print $1}' | xargs -I {} rome upload "{}" --platform iOS # upload what is missing

List workflow

This workflow relies on querying the cache to check for missing dependencies and then selectively telling Carthage what to build. This flow is more fragile as Carthage will refuse to build indirect dependencies.

In code:

#!/bin/bash
rome download --platform iOS # download missing frameworks (or copy from local cache)
rome list --missing --platform iOS | awk '{print $1}' | xargs -I {} carthage bootstrap "{}" --platform iOS --cache-builds # list what is missing and update/build if needed
rome list --missing --platform iOS | awk '{print $1}' | xargs -I {} rome upload "{}" --platform iOS # upload what is missing

If no frameworks are missing, the awk pipe to carthage will fail and the rest of the command will not be executed. This avoids rebuilding all dependencies or uploading artifacts already present in the cache.

Set up

If you plan to use Amazon's S3 as a cache, then follow the next three steps:

• First you need a .aws/credentials file in your home folder. This is used to specify your AWS Credentials.
• Second you need a .aws/config file in your home folder. This is used to specify the AWS Region.
• Third you need a Romefile in the project where you want to use Rome. At the same level where the Cartfile is.

If you just want to use only a local folder as a cache then:

• You need a Romefile in the project where you want to use Rome. At the same level where the Cartfile is. Since 0.17.1.49, if you want to place the Romefile elsewhere or name it differently use --romefile <path-to-romefile> when running rome <COMMAND>.

Setting up AWS credentials

Since version 0.2.0.0 Rome will expect to find credentials either as environment variables $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY or in a file at .aws/credentials. This aligns Rome behavior to other tools that use Amazon's SDK. See Amazon's blogpost on the topic.

In your home folder create a .aws/credentials like the following

[default]
aws_access_key_id = ACCESS_KEY
aws_secret_access_key = SECRET_KEY

this should look something like

[default]
aws_access_key_id = AGIAJQARMD67CE3DTKHA
aws_secret_access_key = TedRV2/dFkBr1H3D7xuPsF9+CBHTjK0NKrJuoVs8

these will be the credentials that Rome will use to access S3 on your behalf. To use configurations other than the default profile set the $AWS_PROFILE environment variable to your desired profile.

Since version 0.21.0.58 Rome also supports privilege escalation via Amazon STS by specifying role_arn and source_profile in ~/.aws/config

Selecting the AWS Region

In your home folder create a .aws/config like the following

[default]
region = us-east-1

To use configurations other than the default profile set the $AWS_PROFILE environment variable to your desired profile.

Alternatively the AWS Region can also be specified by setting an AWS_REGION environment variable.

Setting up endpoint override

To your .aws/config in the profile section you wish to use, add an endpoint key like so

[default]
region = us-east-1
endpoint = https://my.minio.host:9091

Do not remove the region key.

Default port for https endpoints is 443 if the port is left unspecified.

Default port for http endpoints is 9000 if the port is left unspecified.

Alternatively the endpoint can also be specified by setting an AWS_ENDPOINT environment variable.

Custom Engine

You can write your own script that Rome will use as engine to execute upload/download/list commands. You start by specifying the path to a script or executable in your Romefile as shown in the example structure. Rome will invoke the specified script or executable with three commands and different parameters based on the action to perform:

• ./script.sh upload local-path remote-path
• ./script.sh download remote-path local-path
• ./script.sh list remote-path

For example, if your Romefile specifies engine: script.sh, Rome will execute the following command when uploading/downloading/listing a framework:

./script.sh upload Alamofire/iOS/Alamofire.framework-4.8.2.zip Alamofire/iOS/Alamofire.framework-4.8.2.zip
./script.sh download Alamofire/iOS/Alamofire.framework-4.8.2.zip Alamofire/iOS/Alamofire.framework-4.8.2.zip
./script.sh list Alamofire/iOS/Alamofire.framework-4.8.2.zip

The script should take the given remote-path, carry out its logic to retrieve the artifact and place it at local-path. Please refer to the cache structure definition for more information on the cache is constructed.

For an example of a custom engine, take a look at engine.sh which is used in the integration tests to simply copy artifacts in a different directory. Infinite uses cases are opened by using a custom engine, such as uploading artifacts to any non-compatible S3 storage system.

Other example engines:

• Google Storage

Romefile

About the format

Since version 0.17.0.48 the Romefile is in YAML format. Rome can still read the INI Romefile, for now.

Sucessive release might abandon compatibility.

Feature support that require additions or changes to the Romefile won't be supported in INI.

You can migrate your Romefile to YAML by running rome utils migrate-romefile.

If you are looking for the documention prior to 0.17.0.48, check the wiki

Purpose

The Romefile has three purposes:

1. Specifies what caches to use - cache key. This key is required.
2. Allows to use custom name mappings between repository names and framework names - repositoryMap key. This key is optional and can be omitted.
3. Allows to ignore certain framework names - ignoreMap key. This key is optional and can be omitted.
4. Allows to specify the current framework's name(s) - currentMap key. This key is optional and can be omitted.

Structure

A Romefile is made of 4 objects, of which only one, the cache, is required.

• A cache definition object
• A repositoryMap made of a list of Romefile Entry
• An ignoreMap made of a list of Romefile Entry
• A currentMap made of a list of Romefile Entry

Each Romefile Entry is made of:

• A name
• A type which can be static or dynamic
• A set of supported platforms including iOS, Mac, tvOS, watchOS

A Romefile looks like this:

cache: # required
  # at least one of the following is required:
  local: ~/Library/Caches/Rome # optional and can be combined with either a `s3Bucket` or `engine`
  s3Bucket: ios-dev-bucket # optional and can be combined with `local`
  engine: script.sh # optional and can be combined with `local`
                    
repositoryMap: # optional
- better-dog-names: # entry that does not follow
                    # the "Organization/FrameworkName" convention.
  - name: DogFramework # required
    type: static # optional, defaults to dynamic
- HockeySDK-iOS:
  - name: HockeySDK
    platforms: [iOS] # optional, all platforms if empty
- awesome-framework-for-cat-names:
  - name: CatFramework
    type: dynamic
ignoreMap:
- GDCWebServer:
  - name: GDCWebServer
currentMap:
- animal-names-framework:
  - name: AnimalNames

Cache

The cache must contain at least one between:

• the name of the S3 Bucket to upload/download to/from. The key s3Bucket is optional.
• the path to local directory to use as an additional cache. The key local is optional.
• the path to a custom engine to use as an additional cache. The key engine is optional.

cache: # required
  local: ~/Library/Caches/Rome # optional
                               # at least one between `local`, `s3bucket` and `engine` is required
  s3Bucket: ios-dev-bucket # optional
                           # at least one between `local`, `s3bucket` and `engine` is required
  engine: script.sh        # optional
                           # at least one between `local`, `s3bucket` and `engine` is required

This is already a viable Romefile.

RepositoryMap

This contains the mappings of repository and framework names. This is particularly useful if dependecies are not on GitHub or don't respect the "Organization/FrameworkName" convention.

Example:

Suppose you have the following in your Cartfile

github "Alamofire/Alamofire" ~> 4.3.0
github "bitstadium/HockeySDK-iOS" "3.8.6"
git "http://stash.myAnimalStartup.com/scm/iossdk/awesome-framework-for-cat-names.git" ~> 3.3.1
git "http://stash.myAnimalStartup.com/scm/iossdk/better-dog-names.git" ~> 0.4.4

which translates to the following Cartfile.resolved

github "Alamofire/Alamofire" "4.3.0"
github "bitstadium/HockeySDK-iOS" "3.8.6"
git "http://stash.myAnimalStartup.com/scm/iossdk/awesome-framework-for-cat-names.git" "3.3.1"
git "http://stash.myAnimalStartup.com/scm/iossdk/better-dog-names.git" "0.4.4"

but your framework names are actually HockeySDK, CatFramework and DogFramework as opposed to HockeySDK-iOS, awesome-framework-for-cat-names and better-dog-names.

simply add a repositoryMap key to your Romefile and specify the following mapping:

cache:
  local: ~/Library/Caches/Rome 
repositoryMap:
- better-dog-names: # this is the Romefile Entry for  `better-dog-names`
  - name: DogFramework
    type: static
    platforms: [iOS, Mac]
- HockeySDK-iOS: # this is the Romefile Entry for  `HockeySDK-iOS`
  - name: HockeySDK
    platforms: [iOS]
- awesome-framework-for-cat-names:  # this is the Romefile Entry for  `awesome-framework-for-cat-names`
  - name: CatFramework
  - type: dynamic

Note that it was not necessary to add Alamofire as it respects the "Organization/FrameworkName" convention.

IgnoreMap

This contains the mappings of repository and framework names that should be ignored. This is particularly useful in case not all your Cartfile.resolved entries produce a framework.

Some repositories use Carthage as a simple mechanism to include other git repositories that do not produce frameworks. Even Carthage itself does this, to include xcconfigs.

Example:

Suppose you have the following in your Cartfile

github "Quick/Nimble"
github "jspahrsummers/xcconfigs"

xcconfigs can be ignored by Rome by adding an ignoreMap key in the Romefile

ignoreMap:
- xcconfigs:
  - name: xcconfigs

Each entry in the IgnoreMap is also a Romefile Entry and supports all keys.

CurrentMap

By default the currentMap is not used. Specify --no-skip-current as a command line option to use it. It is supported by Rome versions greater than 0.18.x.y and can be specified only in YAML.

The currentMap contains the mappings of repository and framework name(s) that describe the current framework. This is particularly useful if you want to use Rome in the context of a framework. It is the equivalent of Carthage's --no-skip-current.

currentMap:
- Alamofire:
  - name: Alamofire

Each entry in the currentMap is also a Romefile Entry and supports all keys.

The currentMap is subject to the ignores specified in the ignoreMap. If you explicitly specify names of frameworks to upload, download on the command line, you don't need to pass --no-skip-current to use the currentMap. Just specify the name(s) of the current framework.

The version of the current framework is determined by

git describe --tags --exact-match `git rev-parse HEAD`

If the commands does not resolve to any tag, the HEAD commit hash from git rev-parse HEAD is used as version.

In order for --no-skip-current to work, make sure to run carthage archive to create an artifact to cache.

Multiple Aliases

Suppose you have a framework Framework that builds two targets, t1 and t2, Rome can handle both targets by specifying

repositoryMap:
- Framework:
  - name: t1
  - name: t2

Note: if ANY of the aliases is missing on S3, the entire entry will be reported as missing when running rome list [--missing]

Multiple aliases are supported in ignoreMap too

Static Frameworks

Since version 0.30.1 Carthage has support for Static Frameworks. To indicate that one of the aliases is a Static Framework, modify the repositoryMap like so:

repositoryMap:
- Framework:
  - name: t1
    type: static
  - name: t2

If left unspecified, an alias is a Dynamic Framework by default.

Platforms

Since version 0.17.1.49 Rome allows you to specify what platforms are supported for a specific Romefile Entry. This serves a differet purpose than the command line option --platforms.

repositoryMap:
- Framework: 
  - name: t1
    type: static
    platforms: [iOS, Mac]
  - name: t2

The above means that t1 is only available for iOS and Mac. The --platforms command line options can be used to futher limit the Rome command to a specific subset of the supported platfroms.

Cache Structure

The following describes the structure of the cache that Rome creates and manages.

By default frameworks, dSYMs and .bcsymbolmaps are placed in the cache (local and/or remote) according to the following convention:

<git-repository-name>/<platform>/<framework-name>.framework(.dSYM)-(static-)<version-hash>.zip
<git-repository-name>/<platform>/<bcsymbolmap-hash>.bcsymbolmap-(static-)<version-hash>.zip

Carthage version files are placed at:

<git-repository-name>/.<framework-name>.version-(static-)<version-hash>

For example the cache for the Cartfile.resolved in RepositoryMap would look like the following

/Users/blender/Library/Caches/Rome/

		│   ├── DogFramework.framework-v4.0.0.zip
		│   └── DogFramework.framework.dSYM-v4.0.0.zip
		└── .DogFramework.version-v4.0.0

Cache Prefix

Since version 0.12.0.31 Rome supports prefixes for top level directories in your caches. You can append --cache-prefix MY_PREFIX to all commands. This simply means that both the framework/dSYM and .version file conventional locations can be prefixed by another directory of your choosing. Thus the conventions become:

<MY_PREFIX>/<git-repository-name>/<platform>/<framework-name>.framework(.dSYM)-<version-hash>.zip

and

<MY_PREFIX>/<git-repository-name>/.<framework-name>.version-<version-hash>

This is particularly useful when the need to cache frameworks at the same version but build with different versions of the compiler arises.

Suppose you want to cache v4.0.0 of DogFramework build for Swift2.1/Swift3.1/Swift3.2/Swift4. Once built you can upload each build with the same version number to a separate top level directory in the cache via the --cache-prefix option.

Thus running for the Swift2.1 build

$ rome upload better-dog-names --platform iOS # note there is no prefix here

and running for the the Swift3.2 build

$ rome upload better-dog-names --platform iOS --cache-prefix Swift_3_2

would lead to the following cache structure

/Users/blender/Library/Caches/Rome/
├── better-dog-names
│   ├── iOS
│   │   ├── DogFramework.framework-v4.0.0.zip
│   │   └── DogFramework.framework.dSYM-v4.0.0.zip
│   └── .DogFramework.version-v4.0.0-iOS
└── Swift_3_2
    └── better-dog-names
        ├── iOS
        │   ├── DogFramework.framework-v4.0.0.zip
        │   └── DogFramework.framework.dSYM-v4.0.0.zip
        └── .DogFramework.version-v4.0.0-iOS

Uploading

Uploading one or more frameworks, corresponding dSYMs, .bcsymbolmaps and Carthage version files if present (an empty list of frameworks will upload all frameworks found in Cartfile.resolved):

Referring to the Cartfile.resolved in RepositoryMap

$ rome upload Alamofire
Uploaded Alamofire to: Alamofire/iOS/Alamofire.framework-4.3.0.zip
Uploaded Alamofire.dSYM to: Alamofire/iOS/Alamofire.framework.dSYM-4.3.0.zip
Uploaded Alamofire to: Alamofire/tvOS/Alamofire.framework-4.3.0.zip
Uploaded Alamofire.dSYM to: Alamofire/tvOS/Alamofire.framework.dSYM-4.3.0.zip
Uploaded Alamofire to: Alamofire/watchOS/Alamofire.framework-4.3.0.zip
Uploaded Alamofire.dSYM to: Alamofire/watchOS/Alamofire.framework.dSYM-4.3.0.zip

Uploading for a specific platform (all platforms are uploaded by default):

$ rome upload --platform ios Alamofire
Uploaded Alamofire to: Alamofire/iOS/Alamofire.framework-4.3.0.zip
Uploaded Alamofire.dSYM to: Alamofire/iOS/Alamofire.framework.dSYM-4.3.0.zip

If a local cache is specified in your Romefile and you wish to ignore it pass --skip-local-cache on the command line.

Since version 0.20.0.56, if you are on a fast Internet connection you can use the --concurrently flag to maximise concurrency for the operation and maximise bandwith use. Using the --concurrently flag should result in a x3 speedup.

Downloading

Downloading one or more frameworks, corresponding dSYMs, .bcsymbolmaps and Carthage version files if present (an empty list of frameworks will download all frameworks found in Cartfile.resolved):

Listing

Listing frameworks and reporting on their availability:

$ rome list
Alamofire 4.3.0 : +iOS -macOS +tvOS +watchOS
ResearchKit 1.4.1 : +iOS -macOS -tvOS -watchOS

Listing only frameworks present in the cache:

$ rome list --present
Alamofire 4.3.0 : +iOS +tvOS +watchOS
ResearchKit 1.4.1 : +iOS

Listing only frameworks missing from the cache:

$ rome list --missing
Alamofire 4.3.0 : -macOS
ResearchKit 1.4.1 : -macOS -tvOS -watchOS

Listing frameworks missing for specific platforms:

$ rome list --missing --platform watchos,tvos
ResearchKit 1.4.1 : -tvOS -watchOS

Forwarding a list of missing frameworks to Carthage for building:

$ rome list --missing --platform ios | awk '{print $1}' | xargs -I {} carthage build "{}" --platform ios
*** xcodebuild output can be found in ...

Since version 0.13.0.33 list results can also be printed as JSON by specifying --print-format=JSON

Note: list completely ignores dSYMs, bcsymbolmap and Carthage version files. If a dSYM or a Carthage version file is missing, the corresponding framework is still reported as present.

Troubleshooting & FAQ

Getting "Image not found" when running an application using binaries

Implicit dependencies of frameworks when using binaries are not copied over by Xcode automatically despite "Always Embed Standard Libraries" set to YES (see 56).

Here is an example with ReactiveCocoa, which depends on CoreLocation and MapKit. If ReactiveCocoa is built via Carthage or as a Xcode subproject, CoreLocation and MapKit are copied into the app's bundle. On the other hand, when using the binary, Xcode has no clue of that and does not copy the necessary frameworks even if "Always Embed Standard Libraries" is set to yes.

To fix that, add an explicit import statement to one of your files:

// Implicit ReactiveCocoa Dependencies

import CoreLocation
import MapKit

Supporting multiple Swift Versions

Storing artifacts or a the same famework at different Swift versions can be achieved by specifying a cache prefix when using any Rome command like so:

$ rome upload --platform iOS --cache-prefix Swift3 Alamofire
$ rome download --platform iOS --cache-prefix Swift3 Alamofire
$ rome list --platform iOS --cache-prefix Swift3

If you prefer a more accurate way of generating cache prefixes for different swift versions consider using the following:

--cache-prefix `xcrun swift --version | head -1 | sed 's/.*\((.*)\).*/\1/' | tr -d "()" | tr " " "-"`

The specified prefix is prepended to the git repository name in the caches. Using a local cache path like ~/Library/Caches/Rome will store Alamofire from the example above at ~/Library/Caches/Rome/Swift3/Alamofire

See Cache Structure and Cache Prefix for an in depth explanation.
