deb-buildinfo - Debian build information file format
Each Debian source package build can record the build information
in a .buildinfo control file, which contains a number of fields in
deb822(5) format.
Each field begins with a tag, such as Source or
Binary (case insensitive), followed by a colon, and the body of the
field (case sensitive unless stated otherwise). Fields are delimited only by
field tags. In other words, field text may be multiple lines in length, but
the installation tools will generally join lines when processing the body of
the field (except in case of the multiline fields
Binary-Only-Changes, Installed-Build-Depends,
Environment, Checksums-Md5, Checksums-Sha1 and
Checksums-Sha256, see below).
The control data might be enclosed in an OpenPGP ASCII Armored
signature, as specified in RFC4880.
The name of the .buildinfo file will depend on the type of
build and will be as specific as necessary but not more; for a build that
includes any the name will be
source-name_binary-version_arch.buildinfo,
or otherwise for a build that includes all the name will be
source-name_binary-version_all.buildinfo,
or otherwise for a build that includes source the name will be
source-name_source-version_source.buildinfo.
- Format:
format-version (required)
- The value of this field declares the format version of the file. The
syntax of the field value is a version number with a major and minor
component. Backward incompatible changes to the format will bump the major
version, and backward compatible changes (such as field additions) will
bump the minor version. The current format version is 1.0.
- Source:
source-name [(source-version)]
(required)
- The name of the source package. If the source version differs from the
binary version, then the source-name will be followed by a
source-version in parenthesis. This can happen when the build is
for a binary-only non-maintainer upload.
- Binary:
binary-package-list (required in context)
- This folded field is a space-separated list of binary packages built. If
the build is source-only, then the field is omitted (since dpkg
1.20.0).
- Architecture:
arch-list (required)
- This space-separated field lists the architectures of the files currently
being built. Common architectures are amd64, armel,
i386, etc. Note that the all value is meant for packages
that are architecture independent. If the source for the package is also
being built, the special entry source is also present. Architecture
wildcards must never be present in the list.
- Version:
version-string (required)
- Typically, this is the original package's version number in whatever form
the program's author uses. It may also include a Debian revision number
(for non-native packages). The exact format and sorting algorithm are
described in deb-version(7).
- Binary-Only-Changes:
- changelog-entry
- This multiline field contains the concatenated text of the changelog entry
for a binary-only non-maintainer upload (binNMU) if that is the case. To
make this a valid multiline field empty lines are replaced with a single
full stop (‘.’) and all lines are indented by one space
character. The exact content depends on the changelog format.
- Checksums-Md5:
(required)
- Checksums-Sha1:
(required)
- Checksums-Sha256:
(required)
- checksum size filename
- These multiline fields contain a list of files with a checksum and size
for each one. These fields have the same syntax and differ only in the
checksum algorithm used: MD5 for Checksums-Md5, SHA-1 for
Checksums-Sha1 and SHA-256 for Checksums-Sha256.
The first line of the field value (the part on the same line
as the field name followed by a colon) is always empty. The content of
the field is expressed as continuation lines, one line per file. Each
line consists of space-separated entries describing the file: the
checksum, the file size, and the file name.
These fields list all files that make up the build.
- Build-Origin:
name
- The name of the distribution this package is originating from.
- Build-Architecture:
arch (required)
- The Debian architecture for the installation the packages is being built
in. Common architectures are amd64, armel, i386,
etc.
- Build-Date:
build-date
- The date the package was built. It must be in the same format as the date
in a deb-changelog(5) entry.
- Build-Kernel-Version:
build-kernel-version
- The release and version (in an unspecified format) of the kernel running
on the build system. This field is only going to be present if the builder
has explicitly requested it, to avoid leaking possibly sensitive
information.
- Build-Path:
build-path
- The absolute build path, which correspond to the unpacked source tree.
This field is only going to be present if the vendor has allowed it via
some pattern match to avoid leaking possibly sensitive information.
On Debian and derivatives only build paths starting with
/build/ will emit this field.
- Build-Tainted-By:
- taint-reason-list
- This folded field contains a space-separated list of non-exhaustive reason
tags (formed by alphanumeric and dash characters) which identify why the
current build has been tainted (since dpkg 1.19.5).
On Debian and derivatives the following reason tags can be
emitted:
- merged-usr-via-aliased-dirs
- The system has a merged /usr via aliased directories (previously
known as merged-usr-via-symlinks). This will confuse
dpkg-query, dpkg-statoverride, dpkg-trigger,
update-alternatives and any other tool using pathnames as keys into
their databases, as it creates filesystem aliasing problems, and messes
with the understanding of the filesystem that dpkg has recorded in
its database. For build systems that hardcode pathnames to specific
binaries or libraries on the resulting artifacts, it can also produce
packages that will be incompatible with non-/usr-merged filesystems.
- usr-local-has-configs
- The system has configuration files under /usr/local/etc.
- usr-local-has-includes
- The system has header files under /usr/local/include.
- usr-local-has-programs
- The system has programs under /usr/local/bin or
/usr/local/sbin.
- usr-local-has-libraries
- The system has libraries, either static or shared under
/usr/local/lib.
- can-execute-cross-built-programs
- The system can execute cross built programs, either directly or via some
emulation layer.
Since dpkg 1.21.10.
- Installed-Build-Depends:
(required)
- package-list
- The list of installed and configured packages that might affect the
package build process.
The list consists of each package name, optionally
arch-qualified for foreign architectures, with an exact version
restriction, separated by commas.
The list includes all essential packages, packages listed in
Build-Depends, Build-Depends-Arch,
Build-Depends-Indep source control fields, any vendor specific
builtin dependencies, and all their recursive dependencies. On Debian
and derivatives the dependency builtin is build-essential.
For dependencies coming from the source control fields, all
dependency alternatives and all providers of virtual packages depended
on will be included.
- Environment:
- variable-list
- The list of environment variables that are known to affect the package
build process, with each environment variable followed by an equal sign
(‘=’) and the variable's quoted value, using double quotes
(‘"’), and backslashes escaped
(‘\\’).
