.buildinfo specification

.buildinfo field descriptions

Format

Same as in .changes.

Build-Architecture

The Debian machine architecture that was used to perform the build.

Source

Same as in .changes.

Version

Same as in .changes.

Binary

Same as in .changes.

Architecture

Same as in .changes except source should not be specified: only concrete architectures, no wildcards or any.

Checksums-Sha256

Same format as other control files. Must list the .dsc file and all files listed in `debian/files`.

Build-Environment

List of all packages forming the build environment, their architecture if different from build architecture, and their version. This includes Essential packages, build-essential, and Build-Depends and Build-Depends-Indep. For each packages, their dependencies should be recursively listed. The format is the same as Built-Using.

Build-Path
Absolute path of the directory in which the package has been built.

The content of the Build-Environment is close to what dh-buildinfo currently produces.

.buildinfo signatures

As .buildinfo are meant to enable to reproduce a given build, multiple parties should be able to assess their content. .buildinfo files thus are signed using detached signatures, with the full fingerprint of the key in the filename.

Example file list:

hello_2.8-1_amd64.buildinfo
hello_2.8-1_amd64.buildinfo.0603CCFD91865C17E88D4C798382C95C29023DF9.asc
hello_2.8-1_amd64.buildinfo.0EE5BE979282D80B9F7540F1CCD2ED94D21739E9.asc

Inclusion of .buildinfo in the archive

.buildinfo files will be referenced by their assessers through a Build-Signed-Off-By field in the Packages` index.

Example:

Package: hello
Version: 2.9-1
Installed-Size: 140
Maintainer: Santiago Vila <sanvila@debian.org>
Architecture: i386
[…]
Build-Signed-Off-By:
 0603CCFD91865C17E88D4C798382C95C29023DF9 Jérémy Bobbio <lunar@debian.org>,
 D54C3BFAFFB042DE382DA5D741CE7F0B9F1B8B32 Santiago Vila <sanvila@debian.org> 

Previous ideas

.changes files looked like a good place to record the environment as theylist the checksums of the build products and are signed by either the maintainer or the buildd operator.

But the meaning of .changes files is pretty clear: they describe a transactional change operation on the archive. They are not saved directly in the archive: they are equivalent of a log entry. The name of .changes file is also not specified and multiple operations can have the same name.

(See also 719854 for the first attempt which tried using XC- field in debian/control.)
