CodeQL documentation

SARIF output

CodeQL supports SARIF as an output format for sharing static analysis results.

SARIF is designed to represent the output of a broad range of static analysis tools, and there are many features in the SARIF specification that are considered “optional”. This document details the output produced when using the format type sarifv2.1.0, which corresponds to the SARIF v2.1.0.csd1 specification. For more information on selecting a file format for your analysis results, see the database analyze reference.

SARIF specification and schema

This topic is intended to be read alongside the detailed SARIF specification. For more information on the specification and the SARIF schema, see the SARIF specification documentation on GitHub.

Change notes

Changes between versions

CodeQL version Format type Changes
2.0.0 sarifv2.1.0 First version of this format.

Future changes to the output

The output produced for a given specific format type (for example sarifv2.1.0) may change in future CodeQL releases. We will endeavor to maintain backwards compatibility with consumers of the generated SARIF by ensuring that:

  • No field which is marked as “Always” being generated will be removed.
  • The circumstances under which “Optional” fields are generated may change. Consumers of the CodeQL SARIF output should be robust to the presence or absence of these fields.

New output fields may be added in future releases under the same format type–these are not considered to break backwards compatibility, and consumers should be robust to the presence of newly added fields.

New format argument types may be added in future versions of CodeQL—for example, to support new versions of SARIF. These have no guarantee of backwards compatibility, unless explicitly documented.

Generated SARIF objects

This details each SARIF component that may be generated, along with any specific circumstances. We omit any properties that are never generated.

sarifLog object

JSON property name When is this generated? Notes
$schema Always Provides a link to the SARIF schema.
version Always The version of the SARIF used to generate the output.
runs Always An array containing a single run object, for one language.

run object

JSON property name When is this generated? Notes
tool Always
originalUriBaseIds Always A dictionary of uriBaseIds to artifactLocations representing the original locations on the analysis machine. At a minimum, this will contain the %SRCROOT% uriBaseId, which represents the root location on the analysis machine of the source code for the analyzed project. Each artifactLocation will contain the uri and description properties.
artifacts Always An array containing at least one artifact object for every file referenced in a result.
results Always
newLineSequences Always
columnKind Always
properties Always The properties dictionary will contain the semmle.formatSpecifier, which identifies the format specifier passed to the CodeQL CLI.

tool object

JSON property name When is this generated? Notes
driver Always

toolComponent object

JSON property name When is this generated? Notes
name Always Set to “CodeQL command-line toolchain” for output from the CodeQL CLI tools. Note, if the output was generated using a different tool a different name is reported, and the format may not be as described here.
organization Always Set to “GitHub”.
version Always Set to the CodeQL release version e.g. “2.0.0”.
rules Always An array of reportingDescriptor objects that represent rules. This array will contain, at a minimum, all the rules that were run during this analysis, but may contain rules which were available but not run. For more detail about enabling queries, see defaultConfiguration.

reportingDescriptor object (for rule)

reportingDescriptor objects may be used in multiple places in the SARIF specification. When a reportingDescriptor is included in the rules array of a toolComponent object it has the following properties.

JSON property name When is this generated? Notes
id Always Will contain the @id property specified in the query that defines the rule, which is usually of the format language/rule-name (for example cpp/unsafe-format-string). If your organization defines the @opaqueid property in the query it will be used instead.
name Always Will contain the @id property specified in the query. See the id property above for an example.
shortDescription Always Will contain the @name property specified in the query that defines the rule.
fullDescription Always Will contain the @description property specified in the query that defines the rule.
defaultConfiguration Always A reportingConfiguration object, with the enabled property set to true or false, and a level property set according to the @severity property specified in the query that defines the rule. Omitted if the @severity property was not specified.

artifact object

JSON property name When is this generated? Notes
location Always An artifactLocation object.
index Always The index of the artifact object.
contents Optionally If results are generated using the --sarif-add-file-contents flag, and the source code is available at the time the SARIF file is generated, then the contents property is populated with an artifactContent object, with the text property set.

artifactLocation object

JSON property name When is this generated? Notes
uri Always
index Always
uriBaseId Optionally If the file is relative to some known abstract location, such as the root source location on the analysis machine, this will be set.

result object

The composition of the results is dependent on the options provided to CodeQL. By default, the results are grouped by unique message format string and primary location. Thus, two results that occur at the same location with the same underlying message, will appear as a single result in the output. This behavior can be disabled by using the flag --ungroup-results, in which case no results are grouped.

JSON property name When is this generated? Notes
ruleId Always See the description of the id property in reportingDescriptor object (for rule) .
ruleIndex Always
message Always A message describing the problem(s) occurring at this location. This message may be a SARIF “Message with placeholder”, containing links that refer to locations in the relatedLocations property.
locations Always An array containing a single location object.
partialFingerprints Always A dictionary from named fingerprint types to the fingerprint. This will contain, at a minimum, a value for the primaryLocationLineHash, which provides a fingerprint based on the context of the primary location.
codeFlows Optionally This array may be populated with one or more codeFlow objects if the query that defines the rule for this result is of @kind path-problem.
relatedLocations Optionally This array will be populated if the query that defines the rule for this result has a message with placeholder options. Each unique location is included once.
suppressions Optionally If the result is suppressed, then this will contain a single suppression object, with the @kind property set to IN_SOURCE. If this result is not suppressed, but there is at least one result that has a suppression, then this will be set to an empty array, otherwise it will not be set.

location object

JSON property name When is this generated? Notes
physicalLocation Always
id Optionally location objects that appear in the relatedLocations array of a result object may contain the id property.
message Optionally

location objects may contain the message property if:

  • They appear in the relatedLocations array of a result object may contain the message property.
  • They appear in the threadFlowLocation.location property.

physicalLocation object

JSON property name When is this generated? Notes
artifactLocation Always
region Optionally If the given physicalLocation exists in a text file, such as a source code file, then the region property may be present.
contextRegion Optionally May be present if this location has an associated snippet.

region object

There are two types of region object produced by CodeQL:

  • Line/column offset regions
  • Character offset and length regions

Any region produced by CodeQL may be specified in either format, and consumers should robustly handle either type.

For line/column offset regions, the following properties will be set:

JSON property name When is this generated? Notes
startLine Always
startColumn Optionally Not included if equal to the default value of 1.
endLine Optionally Not included if identical to startLine.
endColumn Always
snippet Optionally

For character offset and length regions, the following properties will be set:

JSON property name When is this generated? Notes
charOffset Optionally Provided if startLine, startColumn, endLine, and endColumn are not populated.
charLength Optionally Provided if startLine, startColumn, endLine, and endColumn are not populated.
snippet Optionally

codeFlow object

JSON property name When is this generated? Notes
threadFlows Always

threadFlow object

JSON property name When is this generated? Notes
locations Always

threadFlowLocation object

JSON property name When is this generated? Notes
