The darc client is a .NET Core global tool. It requires that a .NET Core SDK be installed globally on the machine. The client can be installed using the eng\common\darc-init.ps1 script located under any arcade enabled repository. The version number is currently baked into the install script, so ensuring you have the latest arcade is a good idea.

When executing most operations, the client needs to make some remote queries. These remote queries require authentication in most circumstances. There are 3 PATs that may be used:
- A GitHub PAT for downloading files from GitHub (e.g. eng/Version.Details.xml or arcade script files. Required scopes: None
- An Azure DevOps PAT for downloading files from Azure DevOps. (e.g. eng/Version.Details.xml) Required scopes: Code-Read
- A Build Asset Registry (BAR) password for interacting with Maestro++/BAR (e.g. obtaining build information needed for a drop).
These tokens can either be passed on the command line using parameters (see Common parameters), or
cached locally on the machine using the darc authenticate command.
After supplying your secrets, a simple darc get-channels operations should succeed.

Adding a new dependency to a repository means adding a dependency that is tracked by the Maestro++/darc system. This dependency's version can then be automatically updated, along with its sha and repository uri. It can contribute to the repository dependency graph, and the build producing it will be included in a drop.
Dependencies are tracked in eng/Version.Details.xml, along with the following information about each one:
- Name
- Source sha
- Source repository
- Is the dependency version pinned (can be it automatically updated?)
- Dependency type (toolset or product)
The darc add-dependency command adds a new dependency. It takes a number of
parameters, though only --name and --type are initially required. It is
highly recommended at least the --repo parameter be provided so that the
sha/version data can be filled in using darc update-dependencies. See Toolset
vs. Product Dependencies below for
information on type. For example:
darc add-dependency --name 'Microsoft.NETCore.App' --type 'product' --repo https://github.com/dotnet/core-setup
This will add a new dependency called 'Microsoft.NETCore.App' to eng/Version.Details.xml under the product section. The version, repo, and sha information will be left blank. A corresponding PropertyGroup entry in eng/Versions.props will be added, with the same version number. The property name is derived off of the dependency name, with the .'s and -'s removed and "PackageVersion" added onto the end. Note: If eng/Versions.props's existing version property names end with the suffix 'Version', darc will append that instead.
eng/Versions.props after add command.
<MicrosoftNETCoreAppPackageVersion></MicrosoftNETCoreAppPackageVersion>
After doing this, you can use the generated MicrosoftNETCoreAppPackageVersion
property as inputs to a PackageReference element or wherever else may need a
version number.
After adding, it is recommended that you use darc to fill out the missing dependency information. The information can also be filled in after committing by Maestro++ using dependency flow, but passing your CI without a filled-in version number may be difficult. See Updating dependencies in your local repository
There are two types of dependencies: 'Product' and 'Toolset'. Choosing between them involves answering the question:
"Does my repository repackage the input dependency's binaries, or information about those binaries in the outputs it creates for the product?" If so, that dependency is 'Product', otherwise, it's 'Toolset'.
Some examples:
- Arcade SDK or other arcade packages - These packages are not customer facing and do not ship as part of the product.
- dotnet/corefx's dependency on Microsoft.NETCore.App - This is a circular dependency for testing purposes.
- dotnet/core-setup's dependency on dotnet/coreclr's runtime packages - Even though these packages are not 'shipped' to nuget.org, they are repackaged by dotnet/core-setup.
- dotnet/core-sdk's dependency on dotnet/core-setup - The SDK repackages information about Microsoft.NETCore.App.
- dotnet/winforms's dependency on dotnet/corefx's outputs - Winforms repackages information about the dotnet/corefx api surface area, and thus those dotnet/corefx binaries should be 'shipped'. While we wouldn't necessarily want to ship multiple versions of the same binary in a release, we would ensure that the same dotnet/corefx version is coherent across the stack.
Sometimes it may be useful to update the dependency state of your local repository against the latest builds. This might be useful when:
- Manually updating to create a new PR.
- Filling out missing information (e.g. version and sha) in Version.Details.xml prior to committing a new dependency.
- Updating to the latest binaries on a different channel for testing.
darc reads the Version.Details.xml file and notes the dependency name and repository uri of each dependency. Then, given an input channel, it looks up the latest build of each dependency's repository that has been applied to the channel. It then updates the Version.Details.xml and other version files (e.g. Versions.props) based on the newest information.
Continuing with the example from Adding dependencies to a repository, let's say I just added a dependency on Microsoft.NETCore.App out of core-setup. I want to fill in the missing information prior to check-in. I know that the channel that .NET Core 5 day to day development for core-setup targeting is '.NET Core 5 Dev', so by doing:
PS C:\enlistments\arcade> darc update-dependencies --channel ".NET Core 5 Dev" --name "Microsoft.Netcore.app"
Updating 'Microsoft.NETCore.App': '' => '3.0.0-preview-27401-3' (from build '20190201.3' of 'https://github.com/dotnet/core-setup')
Dependency name normalized to 'Microsoft.NETCore.App'
Local dependencies updated from channel '.NET Core 5 Dev'.

Removing a dependency from a repository involves simply removing the appropriate
Dependency block from eng/Version.Details.xml and committing. At that point, neither darc nor
Maestro++ will know anything about it any longer.
To change a dependency's type, move the Dependency element from the
parent ProductDependencies element into ToolsetDependencies (or vice versa)
and commit. See Toolset
vs. Product Dependencies
By default on each operation (e.g. subscription updates or darc update-dependencies), darc and Maestro will update all applicable dependencies
in eng/Version.Details.xml and associated files. For instance, if a
subscription from core-setup's '.NET Core 5 Dev' channel to core-sdk's master
branch produces 3 outputs, Maestro will attempt to update any matching inputs in
core-sdk's eng/Version.Details.xml file. In some cases, it may be necessary to
pin dependencies so they do not move (e.g. if a breaking change requires
extended work).
This is possible by adding a Pinned="true" attribute to the dependency information. If Pinned is not supplied, the default is "false".

Coherent parent dependencies are a way to relate two dependencies within your repository. A dependency with a coherent parent will update its version based on the version of the dependency that appears within the subtree of the coherent parent. This essentially keeps the dependency from moving 'ahead' of another dependency in your repo.
This is most typically used when referencing corefx, coreclr, and core-setup outputs. Microsoft.NETCore.App encodes information about the corefx and coreclr runtime binaries that it has as dependencies itself. Repositories downstream may need to take dependencies on both Microsoft.NETCore.App as well as specific corefx packages. If the corefx packages move ahead of what is referenced in Microsoft.NETCore.App, issues may occur. Specifying a coherent parent that ties the corefx dependencies to Microsoft.NETCore.App will avoid this.
To specify a coherent parent, add "CoherentParentDependency" attributes in your Version.Details.xml file, as shown below:
PS D:\enlistments\extensions\eng> cat .\Version.Details.xml
<?xml version="1.0" encoding="utf-8"?>
<!--
This file is used by automation to update Versions.props and may be used for other purposes, such as
static analysis to determine the repo dependency graph. It should only be modified manually when adding
or removing dependencies. Updating versions should be done using the `darc` command line tool.
See https://github.com/dotnet/arcade/blob/master/Documentation/Darc.md for instructions on using darc.

Dependency flow is the automatic movement of dependency information between repositories. This is done by Maestro++ keeping track of new builds in each repository and opening PRs in other repositories when those repositories' input dependencies in eng/Version.Details.xml match the outputs of the new builds.
These updates are selective and based on 'subscriptions'. A subscription describes an update operation for a specific repository+branch combination, mapping outputs of a repository that have been applied to a channel (virtual branch) onto matching inputs of the target repository+branch.
For example, a build of dotnet/corefx might be applied to the ".NET Core 5 Dev" channel. dotnet/core-setup maps new outputs of dotnet/corefx on the ".NET Core 5 Dev" channel onto its master branch.
A subscription has a few parts:
- Mapping of source repo + source channel => target repo + target branch
- An update rate (e.g. every day, every build, not at all)
- Whether a subscription is batchable or not. If batchable, all batchable subscriptions targeting the same repo+branch combination will share a PR. Note: Batchable subscriptions is currently only supported by the REST API. Please contact @dnceng to set up batchable subscriptions.
- A set of auto merge policies, if the subscription is not batchable. If batchable, merge policies are set on a repository level rather than a per-subscription level, as they end up shared between several subscriptions. Note: repository merge policies are currently unsupported in darc. Please contact @dnceng to set up repository merge policies.
For additional information and samples, see add-subscription
Whenever you want regular dependency flow between two repositories. For example, every day (when there is a new source build) or on every new build.
There are generally two channels for day to day use in .NET Core 5:
- '.NET Core 5 Dev' - Day to day builds of .NET Core 5 repositories are placed on this channel.
- '.NET Tools - Latest' - Arcade releases are placed on this channel.
So, if you're not adding a dependency on the https://github.com/dotnet/arcade repo, the source channel should be '.NET Core 5 Dev'. If you have other specific needs, contact @dnceng.
Sometimes it's necessary to halt dependency flow into or out of a repository for a period of time. While there are lots of cases where this might be done, here are some typical examples:
- Shutting down changes for a release - The 'last' build of a repository like corefx has been produced, and now needs to propagate to the many places in the repository graph it is referenced.
- A change in another repository has a breaking change - Because Maestro++ can auto-merge PRs, a breaking change that isn't caught by CI might be continually propagated as it is the 'latest' build.
- A specific, isolated dependency of a specific repository needs to be kept at a specific version - A few dependencies of a repository should be kept at a specific version, while the rest are allowed to update.
darc and Maestro++ have a few mechanisms to enable such scenarios:
-
Disabling or deleting a default channel association - By disabling a default channel association for a repo, no new builds of that repo will be automatically assigned to the targeted channel. This effectively halts dependency flow without altering all the subscriptions sourcing from that repository. Furthermore, if a selective fix needs to be flowed, the build containing that fix can be selectively assigned to correct channel and the existing subscriptions will flow as normal.
Today this can only be done by either deleting or disabling an existing default channel association. Examples:
Pausing new flow from aspnet/Extensions:
# Disable by repo+branch+channel darc default-channel-status --disable --repo https://github.com/aspnet/Extensions --branch refs/heads/master --channel ".NET Core 5 Dev" # Disable by id. # Use get-default-channels to get the ID of the default channel association, then use default-channel-status to disable. darc get-default-channels # Find id of association in list (63) https://github.com/aspnet/Extensions @ refs/heads/master -> .NET Core 5 Dev darc default-channel-status --disable --id 63Resuming flow from aspnet/Extensions:
-
Disabling or deleting a subscription - By disabling or deleting a subscription, flow between two specific points can be halted. For instance, if arcade has a breaking change that passed core-setup's CI, then it may be necessary to remove flow temporarily while the issue is dealt with. Today, this is only possible via the command line tool by deleting the subscription, then recreating it when normal flow should be resumed:
Pausing new flow from arcade to core-setup
PS C:\enlistments\arcade> darc get-subscriptions --source-repo arcade --target-repo core-setup https://github.com/dotnet/arcade (.NET Tools - Latest) ==> 'https://github.com/dotnet/core-setup' ('master') - Id: 21e611eb-ab71-410e-ca98-08d61f236c94 - Update Frequency: everyDay - Merge Policies: AllChecksSuccessful ignoreChecks = [ "WIP", "license/cla" ] - Last Build: N/A PS C:\enlistments\arcade> darc delete-subscription --id 21e611eb-ab71-410e-ca98-08d61f236c94 Successfully deleted subscription with id '21e611eb-ab71-410e-ca98-08d61f236c94'Resuming flow:
PS C:\enlistments\arcade> darc add-subscription --channel '.NET Tools - Latest' --target-repo https://github.com/dotnet/core-setup --target-branch master --update-frequency everyDay --all-checks-passed --source-repo https://github.com/dotnet/arcade --ignore-checks 'WIP,license/cli' Successfully created new subscription with id '689a946e-2c12-4b0c-ccf6-08d688804ce4'. -
Pinning specific dependencies - Specific dependencies can be pinned when they should not move. This keeps the dependency from moving without altering subscriptions or channels. This is useful when only a subset of a specific repos dependencies should not move.
To do this, add a
Pinned="true"attribute to the dependency that should not move.PS C:\enlistments\arcade> cat .\eng\Version.Details.xml <?xml version="1.0" encoding="utf-8"?> <Dependencies> <ProductDependencies> <Dependency Name="Microsoft.NETCore.App" Version="3.0.0-preview-27401-3" Pinned="true"> <Uri>https://github.com/dotnet/core-setup</Uri> <Sha>b50554ac9a96fedc8580fa6090b6e9e75a23193b</Sha> </Dependency> </ProductDependencies>Resume flow by removing the attribute or setting its value to "false". '
The dependency graph is the transitive set of dependencies defined by the data in Version.Details.xml.
Each dependency listed contains information on the source of the dependency,
specifically which repository and sha it was generated from. Visiting that repository
at the specified sha will yield another set of dependencies. Transitively
visiting these repository+sha combinations will build up a repository graph. The
graph may have cycles, and the transitive walk is stopped at those nodes. It
may also be stopped at any toolset dependency unless those are specifically
included with --include-toolset.
For detailed information on generating the dependency graph, see
get-dependency-graph.
Incoherencies in the graph are places where the same repo appears twice with different shas, or the same dependency appears twice at different versions (even if it was sourced from the same sha). Incoherencies are caused by multiple paths to the root node that run through the same repository, combined with different flow rates between repositories, varying graph depth, build breaks, etc.
Incoherencies aren't necessarily bad. During most of the development cycle, the graph is highly incoherent. What matters is whether those incoherencies will produce semantic differences in behavior. This is something that can generally only be interpreted by developers/product owners by looking at the substantive differences. The default position for day to day development is that incoherencies are not a big deal, but the default position for a shipping product is that non-toolset incoherencies should be removed. This can be done by halting dependency flow after "final" builds are done of incoherent repos. See Halting and restarting dependency flow for some options here.
For a rough example, let's say that at the end of the shipping cycle core-setup flows its 'last' build to core-sdk and other repos. The graph stabilizes. Then, at the last moment, they make a test only fix and check it in. It flows to core-sdk quickly, but gets held up in the other repos that pull Microsoft.NETCore.App due to them not taking any new PRs. This certainly counts as an incoherency, but because there is no semantic product difference between the two versions in the graph there may be no harm in shipping with that incoherency.
Gathering a drop of the product or subpiece part of the product is a typical activity done by developers, release automation, etc. The darc tool can do this using the Build Asset Registry information alongside the dependency graph information.
A build drop is a gathering of all the outputs of a specific build that were reported to the Build Asset Registry into a local location. Optionally, this build drop may also include any builds that were inputs to this build, based on the dependency information in Version.Details.xml. Builds produce various outputs that go to various locations. For example, they may produce NuGet packages, zips, MSIs, etc. These may be available in the build artifacts, or may be located in various storage accounts. Gather-drop mines the Build Asset Registry for these locations and downloads them all to the local directory.
The drop is generally divided into two sections: shipping and non-shipping. Shipping dependencies are those that must be visible to customers. Non-shipping dependencies are those that generally serve as inter-repo transport. Some examples:
- Packages shipping to nuget.org - Shipping
- Coreclr transport packages - Nonshipping, since they get repackaged by core-setup
- Symbols - Shipping, since they go to symbol servers
You can gather either an isolated or full (includes dependencies) drop for any
build in the repository graph. Since the major components of the .NET Core stack
are rooted at 3 different repositories, gathering a drop of those repositories
will generate a drop for those 3 components and any of their inputs if --full
is supplied.
- https://github.com/dotnet/core-sdk - SDK
- https://github.com/aspnet/AspNetCore - ASP.NET Core
- https://github.com/dotnet/core-setup - Runtime.
gather-drop must be able to find a root build. This root build today is
identified by either a repo+sha combo or a direct BAR build ID. For most
repositories that build on every commit, providing the repo uri and latest sha
will generate a drop:
PS C:\enlistments\core-sdk> git rev-parse HEAD
465a336c7a5ca3af2f6cf5172ddc0ebde620803b
PS C:\enlistments\core-sdk> darc gather-drop --repo https://github.com/dotnet/core-sdk
--commit 465a336c7a5ca3af2f6cf5172ddc0ebde620803b --output-dir C:\scratch\drop
...
If no build exists at that drop, darc will show an error. In this case, you might try other recent shas, or use the BAR swagger API (https://maestro-prod.westus2.cloudapp.azure.com/swagger) to look up a build id. Remember to authenticate using a token from https://maestro-prod.westus2.cloudapp.azure.com/. Better methods of obtaining the root build are coming soon.
The root build can then be provided using --id
PS C:\enlistments\core-sdk> darc gather-drop --id 1234 --output-dir C:\scratch\drop
There are a few common parameters available on every command:
-p, --password- Build Asset Registry password. You can obtain this password by going to https://maestro-prod.westus2.cloudapp.azure.com/, logging in using the link in the top right, then generating a token using the menu in the top right. This setting overrides whatever BAR password was provided throughdarc authenticate.--github-pat- Personal access token used to authenticate GitHub. This is a GitHub PAT used to avoid rate limiting when accessing github to download arcade script files or version files. You only need a GitHub PAT with no authorization scopes checked. This setting overrides whatever GitHub PAT was provided throughdarc authenticate.--azdev-pat- Personal access token used to authenticate to Azure DevOps. This token should have Code Read permissions. This setting overrides whatever Azure DevOps PAT was provided throughdarc authenticate.--bar-uri- URI of the build asset registry service to use. Typically left as its default (https://maestro-prod.westus2.cloudapp.azure.com) This setting overrides the Build Asset Registry URI provided throughdarc authenticate.--verbose- Turn on additional output.--debug- Turn on debug output--help- Display help--version- Display version of darc.
Individual darc commands are described below.
Add a new channel. This creates a new tag that builds can be applied to.
This is not a typical operation and you should consult with the (@dnceng)
engineering team before doing so.
Sample:
PS D:\enlistments\arcade> darc add-channel --name "Foo"
Successfully created new channel with name 'Foo'.
Parameters
-n, --name- (Required). Name of channel to create.-c, --classification- Classification of channel. Defaults to 'dev'. Today, this classification does not affect any functionality-i, --internal- Channel is internal only. This option is currently non-functional

Add a new tracked dependency to the Version.Detail.xml file in your local repo. This dependency is also added to eng/Versions.props as well as global.json (for certain dependencies, such as the Arcade SDK). This new dependency can then be updated using update-dependencies. After merging the changes into the remote github or AzDO repository, the dependency can be updated by Maestro++ if there is a corresponding subscription targeting that repo.
When adding a new dependency, only name and type are required. For a detailed discussion on adding new dependencies to a repository, see Adding dependencies to a repository
Parameters
- -n, --name - (Required) Name of dependency to add. This is the name of the package you wish to track. For example, this might be "Microsoft.NETCore.App" or 'System.Security.Cryptography.Cng'
- -t, --type - (Required) 'toolset' or 'product'. See Adding dependencies to a repository for a discussion on dependency types.
- -v, --version - Dependency version.
- -r, --repo - Repository where the dependency was built.
- -c, --commit - SHA at which the dependency was produced.

Adds a new default channel mapping. A default channel maps each new build of a specific branch of a repository onto a specific channel. While builds can be selectively and manually applied to channels, this is generally inconvenient for day to day development in most cases. In general, until release shutdown, each build of a branch should always be applied to its "normal" channel.
Note that the branch specified should almost always be "refs/heads/{branchName}", unless you explicitly know otherwise.
This is because the BAR reporting functionality pulls the branch name from the Azure DevOps built in pipeline variables, which specify refs/heads/foo vs. foo. If your repository is manually reporting to BAR without using the Arcade templates, then this name may be different.
Default channel mappings can be deleted with delete-default-channel.
Parameters
--channel- (Required) Name of channel that a build of 'branch' and 'repo' should be applied to.--branch- (Required) Build of 'repo' on this branch will be automatically applied to 'channel'. Should generally be "refs/heads/branchName"--repo- (Required) Build of this repo on 'branch' will be automatically applied to 'channel'
Sample
PS D:\enlistments\arcade> darc add-default-channel --channel ".Net Core 5 Dev" --branch refs/heads/master --repo https://github.com/dotnet/arcade
See also:
Adds a new subscription to Maestro++.
A subscription describes an update operation for a specific repository+branch combination, mapping outputs of a repository that have been applied to a channel (virtual branch) onto matching inputs of the target repository+branch.
For example, a build of dotnet/corefx might be applied to the ".NET Core 5 Dev" channel. dotnet/core-setup maps new outputs of corefx on the ".NET Core 5 Dev" channel onto its master branch.
A subscription has a few parts:
- Mapping of source repo + source channel => target repo + target branch
- An update rate (e.g. every day, every build, not at all)
- Whether a subscription is batchable or not. If batchable, all batchable subscriptions targeting the same repo+branch combination will share a PR. Note: Batchable subscriptions are currently unsupported in darc
- A set of auto merge policies, if the subscription is not batchable. If batchable, merge policies are set on a repository level rather than a per-subscription level, as they end up shared between several subscriptions. Note: repository merge policies are currently unsupported in darc
add-subscription has two modes of operation:
- Interactive mode (default) - Interactive mode will take whatever input parameters were provided on the command line (if any) and pop an editor where the user can provide the subscription input parameters.
- Command-line only mode (
-q) - In this mode, the full set of input options must be supplied.
Upon saving and closing the editor, or running the darc command if in command
line mode (-q), the darc tool submits the new subscription to Maestro++. If
successful, the id of the new subscription is returned.
Parameters
-channel- (Required if -q is passed) Name of channel that is the source of the subscription. For a list of channels, see get-channels--source-repo- (Required if -q is passed) Source repository for the subscription. Builds of this repository that appear on the specified--channelwill have matching outputs applied to the inputs (specified in eng/Version.Details.xml) of--target-repoand--target-branch.--target-repo- (Required if -q is passed) Target repository for the subscription. Builds of--source-repothat appear on the specified--channelwill have matching outputs applied to the inputs (specified in eng/Version.Details.xml) of this repo's--target-branch--target-branch- (Required if -q is passed) Target branch for the subscription. Builds of--source-repothat appear on the specified--channelwill have matching outputs applied to the inputs (specified in eng/Version.Details.xml) on this branch of--target-repo.--update-frequency- (Required if -q is passed) Frequency of updates. Valid values are: 'none', 'everyDay', or 'everyBuild'. everyDay is applied at 5am. Subscriptions with 'none' frequency can still be triggered using trigger-subscriptions--all-checks-passed- Merge policy. A PR is automatically merged by Maestro++ if there is at least one check and all are passed. Optionally provide a comma separated list of ignored check with --ignore-checks.--ignore-checks- Merge policy. For use with --all-checks-passed. A set of checks that are ignored. Typically, in github repos the "WIP" and "license/cla" checks are ignored.--no-extra-commits- Merge policy. A PR is automatically merged if no non-bot commits exist in the PR.--no-requested-changes- Merge policy. A PR is automatically merged as long as no changes are requested on the PR.--standard-automerge- Merge policy. A PR is automatically merged if all checks are passed and no changes are requested.-q, --quiet- Non-interactive mode (requires all elements to be passed on the command line).
Sample:
PS D:\enlistments\arcade-services> darc add-subscription --channel ".NET Tools - Latest"
--source-repo https://github.com/dotnet/arcade
--target-repo https://dev.azure.com/dnceng/internal/_git/dotnet-optimization
--target-branch master --update-frequency everyDay --all-checks-passed -q
Successfully created new subscription with id '4f300f68-8800-4b14-328e-08d68308fe30'.
Available merge policies
-
Standard - This is the recommended merge policy. It encompasses two existing merge policies:
- All PR checks must be successful, ignoring typical checks in GitHub in AzDO that do not indicate the quality of the PR (e.g. the WIP check) as well as a check that no changes have been requested on the PR.
YAML format for interactive mode:
- Name: Standard -
AllChecksSuccessful - All PR checks must be successful, potentially ignoring a specified set of checks. Checks might be ignored if they are unrelated to PR validation. The check name corresponds to the string that shows up in GitHub/Azure DevOps.
YAML format for interactive mode:
- Name: AllChecksSuccessful Properties: ignoreChecks: - WIP - license/cla - <other check names> -
RequireChecks - Require that a specific set of checks pass. The check name corresponds to the string that shows up in GitHub/Azure DevOps.
YAML format for interactive mode:
- Name: RequireChecks Properties: checks: - MyCIValidation - CI - <other check names> -
NoExtraCommits - If additional non-bot commits appear in the PR, the PR should not be merged.
YAML format for interactive mode:
- Name: NoExtraCommits

Adds an existing build to a channel.
Much of the time, builds are automatically added to channels with default channel associations (See add-default-channel). Occasionally, automatic assignment is turned off for various reasons but we may still need to assign a specific build to a channel.
This can be done with the add-build-to-channel command. It takes two
parameters:
- Name of the channel you want to assign a build to
- BAR build id of the build to assign to the specified channel. This can be found by looking at the "Publish to Build Asset Registry" leg of an official build.
Parameters
--id- (Required). BAR id of build to assign to channel.--channel- (Required). Channel to assign build to.
Sample
PS D:\enlistments\arcade> darc add-build-to-channel --id 13078 --channel ".NET Core 3 Release"

Any updates currently in progress will not be closed, but will not auto-merge. To obtain the id of a subscription to be deleted, see get-subscriptions.
Sample:
PS D:\enlistments\arcade-services> darc delete-subscription --id 4f300f68-8800-4b14-328e-08d68308fe30
Successfully deleted subscription with id '4f300f68-8800-4b14-328e-08d68308fe30'

Gathers a build drop of a repository into a local directory.
A build drop is a gathering of all the outputs of a specific build that were reported to the Build Asset Registry into a local location. Optionally, this build drop may also include any builds that were inputs to this build, based on the dependency information in Version.Details.xml. Builds produce various outputs that go to various locations. For example, they may produce NuGet packages, zips, MSIs, etc. These may be available in the build artifacts, or may be located in various storage accounts. Gather-drop mines the Build Asset Registry for these locations and downloads them all to the local directory.
gather-drop operates in two modes: normal and full. In normal mode, only the
outputs for the desired build (the 'root' build) are downloaded. In full mode,
the tool will then look up the dependency version information for the sha that
was built, then find the builds that created those inputs. The same is done
until all potential nodes are visited. Traversal will break when a cycle is
reached, when a node has no additional dependencies, or when the dependencies it
has are only toolset and --include-toolset has not been supplied.
The output directory structure is as follows:
- Default:
All outputs will be downloaded under the root folder, in either a 'shipping'
or 'nonshipping' folder (if
--nonshippingis passed and the build contains non-shipping binaries). Under these folders will be two additional folders: 'assets' and 'packages'. Assets contains all non-package outputs, while 'packages' contains all NuGet packages. - If
--separatedis passed: Each repository in the build structure will be placed in a separate directory, with the ID of the build under that directory. Under each build will be a 'shipping' folder and potentially a 'nonshipping' folder (if--nonshippingis passed and the build contains non-shipping binaries). Under these folders will be two additional folders: 'assets' and 'packages'. Assets contains all non-package outputs, while 'packages' contains all NuGet packages.
Parameters
-i, --id- BAR ID of build to download. For information on locating the "root build", see Gathering a build drop-r, --repo- If set, gather a build drop for a build of this repo. Requires --commit. For information on locating the "root build", see Gathering a build drop-c, --commit- Branch, commit or tag to look up and gather a build drop for. For information on locating the "root build", see Gathering a build drop-o, --output-dir- (Required) Output directory to place build drop.-f, --full- Gather the full drop (build and all input builds).-s, --separated- Separate out each source repo in the drop into separate directories.--continue-on-error- Continue on error rather than halting. Allows for gathering drops in cases where some outputs might not be able to be downloaded.--non-shipping- (Default: true) Include non-shipping assets.--overwrite- Overwrite existing files at the destination.--dry-run- Do not actually download files, but print what we would do.--include-toolset- Include toolset dependencies.

Channels:

See also:
Retrieves a list of channels. Channels are something like a virtual cross repository branch. They are a tag that is applied to a build which indicates the purpose of the outputs of that build. Channels are used as sources in a subscription, indicating that the repository wants dependency updates from builds meant for the purpose associated with the channel.
For instance, there is a channel called .NET Core 5 Dev. Builds that appear on
this channel are intended for day to day .NET Core 5 development. Repositories
may have dependencies on other .NET Core repositories when building their own
part of the .NET Core 5 stack. By subscribing to that repository's .NET Core 5 Dev channel, they map .NET Core 5 daily development outputs onto their own
target branch.
Parameters
None.
Sample:
PS D:\enlistments\arcade> darc get-channels
.NET Tools - Latest
.NET Engineering Services - Int
.NET Engineering Services - Prod
.NET Tools - Validation
.NET Core 3 Release
.NET Core 3.1 Dev
.NET Core 3.1 Release
.NET Core 5 Dev
.NET Core 3.0 Internal Servicing
.NET 3 Tools
.NET 3 Tools - Validation
See also:
Retrieves a list of default channel mappings. A default channel maps each new build of a specific branch of a repository onto a specific channel. While builds can be selectively and manually applied to channels, this is generally inconvenient for day to day development in most cases. In general, until release shutdown, each build of a branch should always be applied to its "normal" channel. The internal ID of the default channel association is also presented for convenience with other operations like default-channel-status.
Parameters
--source-repo- Filter by a specific source repository. Matches on substring.--branch- Filter by a branch. Matches on substring.--channel- Filter by a channel name. Matches on substring.
Sample
PS D:\enlistments\websdk> darc get-default-channels --channel ".NET Core 3 release"

Given a starting repository and sha, builds the full repository dependency graph.
The dependency graph is defined by the dependencies in Version.Details.xml.
Each dependency listed contains information on the source of the dependency,
specifically which repository and sha it was generated from. Visiting that repository
at the specified sha will yield another set of dependencies. Transitively
visiting these repository+sha combinations will build up a repository graph. The
graph may have cycles, and the transitive walk is stopped at those nodes. It
may also be stopped at any toolset dependency unless those are specifically
included with --include-toolset.
The graph output comes in 3 forms:
- (Default) A full textual graph representation indicating all involved repositories, their input dependencies, and the repositories that created those input dependencies.
- A 'flat' graph where only unique repository+sha combinations are shown. The individual package dependencies are ignored.
- A graph-viz text format that can be used to generate a visual presentation of the graph.
In flat and full modes, after printing the graph, a set of "incoherencies" and the paths to those incoherences are displayed. Incoherencies are cases where either:
-
The same repository exists in the graph at two different shas
-
The same input dependency exists in the graph at two different versions. While generally this also leads to the same repository existing multiple times in the graph at different shas, it's also possible for the same sha to be built more than once, producing different package versions.
While by default, this command uses remote resources to generate the graph, it's possible to generate if you have all potential input repositories available in a folder with all the necessary shas downloaded. In this mode, starting from the root repository, darc will scan the folder for git repos that contain the input shas to that repository. It will then build up the dependency graph based on that information.
By default, if no parameters are passed, the head sha of the current repository is used as the starting point.
Parameters'
-l, --local- Get the graph using only local information. Requires that repos-folder be passed.--repo- If set, gather dependency information from the remote repository. Requires --version.-v, --version- Branch, commit or tag to look up if looking up version information remotely.--asset-name- Get the graph based on a single asset and not the whole Version.Details.xml contents.--repos-folder- Full path to folder where all the repos are locally stored. i.e. C:\repos--remotes-map- ';' separated key value pair defining the remote to local path mapping.-f, --flat- Returns a unique set of repository+sha combination.--graphviz- Writes the repository graph in GraphViz (dot) form, into the specified file.--output-file- Writes the non-GraphViz (dot) output to the specified file into the specified file.--include-toolset- Include toolset dependencies.--skip-builds- Do not look up build information.--delta-from- (Default: newest-in-graph) Determine the delta of each node in the graph from a target. Valid values: [none, newest-in-channel, newest-in-graph]--coherency- Report coherency information.

Get dependency flow graph in graphviz form. This graph represents inter-repository flow vs. get-dependency-graph which represents current repository inter-dependencies. This visualization can be useful to understand the flow of changes in between repositories. Pictorial graphs can be generated using dot.exe or other GraphViz tools.
Parameters
--graphviz- Writes the flow graph in GraphViz (dot) form, into the specified file.--include-disabled-subscriptions- Include edges that have disabled subscriptions--frequencies- (Default: everyWeek twiceDaily everyDay everyBuild none) Include only subscriptions with the specific update frequencies in the graph.--channel- Only include nodes/edges with flow on this channel.

Retrieves the latest builds matching the specified criteria. If more than one build matches then multiple builds are returned. This is useful for a quick check of what the latest build of a repository is, especially if it has not been assigned to a channel.
Parameters
--repo- (Required). Name of repository to determine the latest build for. Match on substring--channel- Name of channel to query for the latest build on. Match on substring
Sample:
PS D:\enlistments\arcade-services> darc get-latest-build --repo core-setup --channel ".NET Core 5 Dev"

Retrieves information about repository merge policies. Merge policies dictate the checks that must be satisfied for a pull request to be automatically merged. These merge policies come from two sources:
- Non-batchable subscriptions specify their own merge policies.
- Batchable subscriptions share a merge policy per repo+branch combination.
Parameters
--repo- Name of repository to get repository merge policies for. Match on substring--branch- Name of repository to get repository merge policies for. Match on substring--all- List all repositories. Otherwise, branches not targeted by a batchable subscription are not listed.
Sample:
S D:\enlistments\websdk> darc get-repository-policies --repo extensions
Filtered 3 policies for branches not targeted by an active batchable subscription. To include, pass --all.

Retrieves information about existing subscriptions. This command is generally useful to determine what kind of dependency flow will happen on new builds, or to obtain the id of a subscription for use in delete-subscription.
The top line of the listing shows the subscription mapping and is read:
https://github.com/aspnet/AspNetCore (.NET Core 5 Dev) ==> 'https://github.com/dotnet/core-sdk' ('master')
Builds of https://github.com/aspnet/AspNetCore that have been applied to channel ".NET Core 5 Dev" will be applied to the master branch of https://github.com/dotnet/core-sdk.
Parameters
If no parameters are specified, get-subscriptions will show a full list of
Maestro++ subscriptions. This list can be filtered by various input parameters
to be more useful.
--target-repo- Filter by target repo (matches substring unless --exact or --regex is passed).--source-repo- Filter by source repo (matches substring unless --exact or --regex is passed).--channel- Filter by source channel (matches substring unless --exact or --regex is passed).--target-branch- Filter by target branch (matches substring unless --exact or --regex is passed).--exact- Match subscription parameters exactly (cannot be used with --regex).--regex- Match subscription parameters using regex (cannot be used with --exact).

Set merge policies for the specific repository and branch. These policies only apply to batchable subscriptions. When all repository policies are satisfied, the dependency update pull request is automatically merged.
If -q is not passed, the command pops up a edit dialog so that the repository policies may be edited.
Parameters
--repo- Name of repository to set repository merge policies for.--branch- Name of repository to get repository merge policies for.--standard-automerge- Use standard auto-merge policies. GitHub ignores WIP and license/cla checks,Azure DevOps ignores comment, reviewer and work item linking. Neither will auto-merge if changes are requested.--all-checks-passed- PR is automatically merged if there is at least one check and all are passed. Optionally provide a comma separated list of ignored checks with --ignore-checks.--ignore-checks- For use with --all-checks-passed. A set of checks that are ignored.--no-requested-changes- PR is not merged if there are changes requested or the PR has been rejected.--no-extra-commits- PR is automatically merged if no non-bot commits exist in the PR.-q, --quiet- Non-interactive mode (requires all elements to be passed on the command line).
Sample:
PS D:\enlistments\websdk> darc set-repository-policies --repo https://github.com/dotnet/corefx --branch master --standard-automerge -q

Triggers one or more subscriptions. For each subscription triggered, Maestro++ will determine whether the latest build on the source channel of the source repository has been applied (or is currently in PR) to the target repo and branch. If not, a new PR will be created or updated (depending on existing PRs and/or subscription batchability).
This update is not asynchronous and usually takes a few minutes, as Maestro++ needs
to do a fair bit of work in the background. New PRs created by
trigger-subscriptions have dotnet-maestro[bot] as their author.
Like get-subscriptions, trigger-subscriptions takes a number of input parameters
to filter the available subscriptions to the desired set, though at least one
input must be specified. Unless -q, --quiet is specified, darc will ask for
confirmation before sending the trigger request.
Parameters
--id- Trigger subscription by id. Not compatible with other filtering parameters.--target-repo- Filter by target repo (matches substring unless --exact or --regex is passed).--source-repo- Filter by source repo (matches substring unless --exact or --regex is passed).--channel- Filter by source channel (matches substring unless --exact or --regex is passed).--target-branch- Filter by target branch (matches substring unless --exact or --regex is passed).--exact- Match subscription parameters exactly (cannot be used with --regex).--regex- Match subscription parameters using regex (cannot be used with --exact).-q, --quiet- Trigger subscriptions without confirmation. Be careful!
Sample:
PS D:\enlistments\arcade> darc trigger-subscriptions --source-repo arcade --target-repo arcade-services
Will trigger the following 1 subscriptions...
https://github.com/dotnet/arcade (.NET Tools - Latest) ==> 'https://github.com/dotnet/arcade-services' ('master')
Continue? (y/n) y

Updates the local repository's dependencies against a channel.
This operation is similar to what a Maestro++ subscription does, only local. darc reads the Version.Details.xml file and notes the dependency name and repository uri of each dependency. Then, given an input channel, it looks up the latest build of each dependency's repository that has been applied to the channel. It then updates the Version.Details.xml and other version files (e.g. Versions.props) based on the newest information.
This command has two additional non-default modes:
- Use a local package folder as input, avoiding a remote call to the build asset registry (--packages-folder)
- Update a specific dependency to a new version (--name and --version)
This command is especially useful after adding new dependencies to a repository. See Updating dependencies in your local repository for more information.
Parameters
-c, --channel- Channel to pull dependencies from.-n, --name- Optional name of dependency to update. Otherwise all dependencies existing on 'channel' are updated.-v, --version- The new version of dependency with the name specified by --name.--source-repo- Only update dependencies whose source uri contains this string.--packages-folder- An optional path to a folder which contains the NuGet packages whose versions will be used to update existing dependencies.--dry-run- Show what will be updated, but make no changes.
