Note: The CodeQL runner is being deprecated. Please use the CodeQL CLI version 2.6.2 or greater instead. GitHub Enterprise Server 3.3 will be the final release series that supports the CodeQL runner. On GitHub Enterprise Cloud, the CodeQL runner will be supported until March 2022. For more information, see the CodeQL runner deprecation.
Note: Code scanning is in beta in GitHub Enterprise Server 2.22. For the generally available release of code scanning, upgrade to the latest release of GitHub Enterprise Server.
Note: Your site administrator must enable code scanning for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Configuring code scanning for your appliance."
About configuring CodeQL code scanning in your CI system
To integrate code scanning into your CI system, you can use the CodeQL runner. For more information, see "Running CodeQL code scanning in your CI system."
In general, you invoke the CodeQL runner as follows.
$ /path/to-runner/codeql-runner-OS
/path/to-runner/
depends on where you've downloaded the CodeQL runner on your CI system. codeql-runner-OS
depends on the operating system you use. There are three versions of the CodeQL runner, codeql-runner-linux
, codeql-runner-macos
, and codeql-runner-win
, for Linux, macOS, and Windows systems respectively.
To customize the way the CodeQL runner scans your code, you can use flags, such as --languages
and --queries
, or you can specify custom settings in a separate configuration file.
Scanning pull requests
Scanning code whenever a pull request is created prevents developers from introducing new vulnerabilities and errors into the code.
To scan a pull request, run the analyze
command and use the --ref
flag to specify the pull request. The reference is refs/pull/<PR-number>/head
or refs/pull/<PR-number>/merge
, depending on whether you have checked out the HEAD commit of the pull request branch or a merge commit with the base branch.
$ /path/to-runner/codeql-runner-linux analyze --ref refs/pull/42/merge
Note: If you analyze code with a third-party tool and want the results to appear as pull request checks, you must run the upload
command and use the --ref
flag to specify the pull request instead of the branch. The reference is refs/pull/<PR-number>/head
or refs/pull/<PR-number>/merge
.
Overriding automatic language detection
The CodeQL runner automatically detects and scans code written in the supported languages.
- C/C++
- C#
- Go
- Java
- JavaScript/TypeScript
- Python
Code scanning automatically detects and scans code written in the supported languages.
To override automatic language detection, run the init
command with the --languages
flag, followed by a comma-separated list of language keywords. The keywords for the supported languages are cpp
, csharp
, go
, java
, javascript
, and python
.
$ /path/to-runner/codeql-runner-linux init --languages cpp,java
Running additional queries
When you use CodeQL to scan code, the CodeQL analysis engine generates a database from the code and runs queries on it. CodeQL analysis uses a default set of queries, but you can specify more queries to run, in addition to the default queries.
Any additional queries you want to run must belong to a QL pack in a repository. For more information, see "About code scanning."
You can specify a single .ql file, a directory containing multiple .ql files, a .qls query suite definition file, or any combination. For more information about query suite definitions, see "Creating CodeQL query suites."
The following query suites are built into CodeQL code scanning and are available for use.
Query suite | Beschreibung |
---|---|
security-extended | Queries of lower severity and precision than the default queries |
security-and-quality | Queries from security-extended , plus maintainability and reliability queries |
When you specify a query suite, the CodeQL analysis engine will run the queries contained within the suite for you, in addition to the default set of queries.
To add one or more queries, pass a comma-separated list of paths to the --queries
flag of the init
command. You can also specify additional queries in a configuration file.
If you also are using a configuration file for custom settings, and you are also specifying additional queries with the --queries
flag, the CodeQL runner uses the additional queries specified with the --queries
--queries
+
symbol. For examples of configuration files, see "Example configuration files."
In the following example, the +
symbol ensures that the CodeQL runner uses the additional queries together with any queries specified in the referenced configuration file.
$ /path/to-runner/codeql-runner-linux init --config-file .github/codeql/codeql-config.yml
--queries +security-and-quality,octo-org/python-qlpack/show_ifs.ql@main
Using a third-party code scanning tool
Instead of passing additional information to the CodeQL runner commands, you can specify custom settings in a separate configuration file.
The configuration file is a YAML file. It uses syntax similar to the workflow syntax for GitHub Actions, as illustrated in the examples below. Weitere Informationen findest Du unter „Workflow-Syntax für GitHub Actions“.
Use the --config-file
flag of the init
command to specify the configuration file. The value of --config-file
$ /path/to-runner/codeql-runner-linux init --config-file .github/codeql/codeql-config.yml
The configuration file can be located within the repository you are analyzing, or in an external repository. Using an external repository allows you to specify configuration options for multiple repositories in a single place. When you reference a configuration file located in an external repository, you can use the OWNER/REPOSITORY/FILENAME@BRANCH syntax. For example, octo-org/shared/codeql-config.yml@main.
Example configuration files
This configuration file adds the security-and-quality
query suite to the list of queries run by CodeQL when scanning your code. For more information about the query suites available for use, see "Running additional queries."
name: "My CodeQL config"
queries:
- uses: security-and-quality
The following configuration file disables the default queries and specifies a set of custom queries to run instead. It also configures CodeQL to scan files in the src directory (relative to the root), except for the src/node_modules directory, and except for files whose name ends in .test.js. Files in src/node_modules and files with names ending .test.js are therefore excluded from analysis.
name: "My CodeQL config"
disable-default-queries: true
queries:
- name: Use an in-repository QL pack (run queries in the my-queries directory)
uses: ./my-queries
- name: Use an external JavaScript QL pack (run queries from an external repo)
uses: octo-org/javascript-qlpack@main
- name: Use an external query (run a single query from an external QL pack)
uses: octo-org/python-qlpack/show_ifs.ql@main
- name: Use a query suite file (run queries from a query suite in this repo)
uses: ./codeql-qlpacks/complex-python-qlpack/rootAndBar.qls
paths:
- src
paths-ignore:
- src/node_modules
- '**/*.test.js'
Configuring code scanning for compiled languages
For the compiled languages C/C++, C#, and Java, CodeQL builds the code before analyzing it. CodeQL also runs a build for Go projects to set up the project. However, in contrast to the other compiled languages, all Go files in the repository are extracted, not just those that are built. You can use custom build commands to skip extracting Go files that are not touched by the build.
For many common build systems, the CodeQL runner can build the code automatically. To attempt to build the code automatically, run autobuild
between the init
and analyze
steps. Note that if your repository requires a specific version of a build tool, you may need to install the build tool manually first.
The autobuild
process only ever attempts to build one compiled language for a repository. The language automatically selected for analysis is the language with the most files. If you want to choose a language explicitly, use the --language
flag of the autobuild
command.
$ /path/to-runner/codeql-runner-linux autobuild --language csharp
If the autobuild
command can't build your code, you can run the build steps yourself, between the init
and analyze
steps. For more information, see "Running CodeQL code scanning in your CI system."
Uploading code scanning data to GitHub
By default, the CodeQL runner uploads results from code scanning when you run the analyze
command. You can also upload SARIF files separately, by using the upload
command.
Once you've uploaded the data, GitHub displays the alerts in your repository.
- If you uploaded to a pull request, for example
--ref refs/pull/42/merge
or--ref refs/pull/42/head
, then the results appear as alerts in a pull request check. For more information, see "Triaging code scanning alerts in pull requests." - If you uploaded to a branch, for example
--ref refs/heads/my-branch
, then the results appear in the Security tab for your repository. For more information, see "Managing code scanning alerts for your repository."
