NAME
deb-buildinfo - Debian build information file format
SYNOPSIS
filename.buildinfo
DESCRIPTION
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; the name will
be:
source-name_binary-version_arch.buildinfo
for a build that includes any
source-name_binary-version_all.buildinfo
otherwise for a build that includes all
source-name_source-version_source.buildinfo
otherwise for a build that includes source
FIELDS
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, weak)
Checksums-Sha1: (required, weak)
Checksums-Sha256: (required, strong)
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.
Note: The MD5 and SHA-1 checksums are considered weak, and
should never be assumed to be sufficient for secure
verification.
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
(‘\\’).
