NAME

dub-dustmite − Create reduced test cases for build errors

SYNOPSIS

dub dustmite <destination-path> OPTIONS... [-- <application arguments...>]

DESCRIPTION

This command uses the Dustmite utility to isolate the cause of build errors in a DUB project.

It will create a copy of all involved packages and run dustmite on this copy, leaving a reduced test case.

Determining the desired error condition is done by checking the compiler/linker status code, as well as their output (stdout and stderr combined). If --program-status or --program-regex is given and the generated binary is an executable, it will be executed and its output will also be incorporated into the final decision.

OPTIONS

−−compiler−status=VALUE

The expected status code of the compiler run

−−compiler−regex=VALUE

A regular expression used to match against the compiler output

−−linker−status=VALUE

The expected status code of the linker run

−−linker−regex=VALUE

A regular expression used to match against the linker output

−−program−status=VALUE

The expected status code of the built executable

−−program−regex=VALUE

A regular expression used to match against the program output

−−test−package=VALUE

Perform a test run - usually only used internally

−−combined

Builds multiple packages with one compiler run

−−no−redirect

Don’t redirect stdout/stderr streams of the test command

−−strategy=VALUE

Set strategy (careful/lookback/pingpong/indepth/inbreadth)

−j

Set number of look-ahead processes

−−trace

Save all attempted reductions to DIR.trace

−b, −−build=VALUE

Specifies the type of build to perform. Note that setting the DFLAGS environment variable will override the build type with custom flags. Possible names:
debug, plain, release, release-debug, release-nobounds, unittest, profile, profile-gc, docs, ddox, cov, cov-ctfe, unittest-cov, unittest-cov-ctfe, syntax and custom types

−c, −−config=VALUE

Builds the specified configuration. Configurations can be defined in dub.json

−−override−config=VALUE

Uses the specified configuration for a certain dependency. Can be specified multiple times. Format: --override-config=<dependency>/<config>

−−compiler=VALUE

Specifies the compiler binary to use (can be a path). Arbitrary pre- and suffixes to the identifiers below are recognized (e.g. ldc2 or dmd-2.063) and matched to the proper compiler type:
dmd, gdc, ldc, gdmd, ldmd

−a, −−arch=VALUE

Force a different architecture (e.g. x86 or x86_64)

−d, −−debug=VALUE

Define the specified debug version identifier when building - can be used multiple times

−−nodeps

Do not resolve missing dependencies before building

−−build−mode=VALUE

Specifies the way the compiler and linker are invoked. Valid values:
separate (default), allAtOnce, singleFile

−−single

Treats the package name as a filename. The file must contain a package recipe comment.

−−force−remove

Deprecated option that does nothing.

−−filter−versions

[Experimental] Filter version identifiers and debug version identifiers to improve build cache efficiency.
