autospec is a tool to assist in the automated creation and maintainence of RPM packaging. It will continuously run updated builds based on new information discovered from build failures, until it has a complete and valid .spec file. The tool makes use of mock to achieve this.
autospec is available under the terms of the GPL, version 3.0

autospec is configured by means of a simple INI-style configuration file. The default location of this file is assumed to be common/autospec.conf
, relative to the directory in which autospec is executed.
Example autospec.conf
file:
[autospec]
git = git@someurl.com/%(NAME)s
license_fetch = http://yourhost/hash.php
license_show = http://yourhost/showone.php?hash=%(HASH)s
upstream = http://yourhost/tarballs/%(HASH)s/%(NAME)s
- git
The upstream git repository URL base
- license_fetch
Optional URL to use for scanning license files
- license_show
Optional URL to interact with online license checker
- upstream
Base URL for stored upstream tarballs
Usage: python3 autospec.py [options] URL
-h, --help show help message and exit -g, --skip-git Don't commit result to git -n NAME, --name NAME Override the package name -a ARCHIVES, --archives ARCHIVES tarball URLs for additional source archives and a location for the sources to be extacted to (e.g. http://example.com/downloads/dependency.tar.gz /directory/relative/to/extract/root ) -l, --license-only Only scan for license files -b, --skip-bump Don't bump release number -c CONFIG, --config CONFIG Set configuration file to use
In order to run correctly, autospec
requires the following components:
- python3
- correctly configured mock
If autospec
is not configured to use a license server, then you will need a common/licenses
file - which should be an up to date list of licenses to facilitate automatic license detection during the scan of a tarball. For correctness, license names should be in the SPDX identifier format. Each line in the file constitutes a license definition, for example:
750b9d9cc986bfc80b47c9672c48ca615cac0c87 | BSD-3-Clause
175e59be229a5bedc6be93e958a970385bb04a62 | Apache-2.0
794a893e510ca5c15c9c97a609ce47b0df74fc1a | BSD-2-Clause
It is possible to influence precisely how autospec will behave in order to gain fine control over the build itself. These files may be used to alter the default behaviour of the configure routine, to blacklist build dependencies from being automatically added, and such.
These files are expected to live in same directory that the resulting .spec
will live.
release
This file contains the current release number that will be used in the
.spec
. This is also bumped and generated on existing and new packages, respectively. This results in less manual work via automatic management.
$package.license
In certain cases, the package license may not be automatically discovered. In this instance,
autospec
will exit with an error. Update this file to contain the valid SPDX identifier for any license(s) for the package, replacing$package
in the filename with the actual package name.
buildreq_add
Each line in the file provides the name of a package to add as a build dependency to the
.spec
.
pkgconfig_add
Each line in the file is assumed to be a pkgconfig() build dependency. Add the pkg-config names here, as
autospec
will automatically transform the names into theirpkgconfig($name)
style when generating the.spec
.
buildreq_ban
Each line in the file is a build dependency that under no circumstance should be automatically added to the build dependencies. This is useful to block automatic configuration routines adding undesired functionality, or to omit any automatically discovered dependencies during tarball scanning.
pkgconfig_ban
Each line in this file is a pkgconfig() build dependency that should not be added automatically to the build, much the same as
buildreq_ban
. As withpkgconfig_add
, these names are automatically transformed byautospec
into their correctpkgconfig($name))
style.
configure
This file contains configuration flags to pass to the
%configure
macro for autotools based tarballs. As an example, adding--disable-static
to./configure
for an autootools based tarball would result in%configure --disable-static
being emitted in the.spec
.
cmake_args
This file contains arguments that should be passed to the
%cmake
macro for CMake based tarballs. As an example, adding-DUSE_LIB64=ON
to./cmake_args
would result in%cmake -DUSE_LIB64=ON
being emitted in the.spec
.
broken_parallel_build
If this file exists, then parallelisation will be disabled in the build. This usually means that
%{?_smp_mflags}
will not be passed tomake
make_args
The contents of this file are appended to the
make
invocation. This may be useful for passing arguments tomake
, i.e.make TOOLDIR=/usr
make_install_args
Much like
make_args
, this will pass arguments to themake install
macro in the.spec
install_macro
The contents of this file be used instead of the automatically detected
install
routine, i.e. use this if%make_install
is insufficient.
subdir
Not all packages have their
Makefile
's available in the root of the tarball. An example of this may be cross-platform projects that split Makefile's into theunix
subdirectory. Set the name in this file and the.spec
will emit the correctpushd
andpopd
lines to utilise these directories for each step in the build.
build_pattern
In certain situations, the automatically detected build pattern may not work for the given package. This one line file allows you to override the build pattern that
autospec
will use. The supported build_pattern types are:
- configure: Traditional
%configure
autotools route- configure_ac: Like
configure, but performs
%reconfigureto regenerate
./configure``- autogen: Similar to
configure_ac
but uses the existing./autogen.sh
instead of%reconfigure
- distutils: Only build the Pythonic package with Python 2
- distutils23: Build the Pythonic package using both Python 2 and Python 3
series
This file contains a list of patches to apply during the build, using the
%patch
macro. As such it is affected by-p1
style modifiers.
excludes
This file is used to generate
%exclude
lines in the.spec
. This is useful for omitting files from being included in the resulting package. Each line in the file should be a full path name.
keepstatic
If this file exists, then
%define keepstatic 1
is emitted in the.spec
. As a result, any static archive (.a
) files will not be removed by rpmbuild.
extras
Each line in the file should be a full path within the resulting package, that you wish to be placed into an automatic
-extras
subpackage. This allows one to keep the main package slim and split out optional functionality or files.
setuid
Each line in this file should contain the full path to a binary in the resulting build that should have the
setuid
attribute set with the%attr
macro.
attrs
Each line in this file should be a full
%attr
macro line that will be included in the.spec
to have fine-grained control over the permissions and ownership of files in the package.
By default, autospec
will attempt to detect potential test suites that can be run in the %check
portion of the .spec
.
skip_test_suite
If this file exists,
autospec
will not emit any%check
functionality.
unit_tests_must_pass
This file is automatically created upon successful completion of a package build. This allows one to identify regressions in test failures when updating or altering a package.
autospec
will fail a package that does not pass it's test suite if this file exists.
make_check_command
Override or set the command to use in the
%check
portion of the.spec
. This may be useful when a package uses a custom test suite, or requires additional work/parameters, to work correctly.
allow_test_failures
The existence of this file will allow test failures, and will still emit the
%check
code in a way that allows the build to continue.
asneeded
If this file exists, the
.spec
will disable the LD_AS_NEEDED variable. Supporting binutils (such as found in Clear Linux Project for Intel Architecture) will then revert to their normal behaviour, instead of enforcing-Wl,-as-needed
in the most correct sense.
optimize_size
If this file exists, the
CFLAGS/LDFLAGS
will be extended to build the package optimised for size, and not for speed. Use this when size is more critical than performance.
funroll-loops
If this file exists, the
CFLAGS/LDFLAGS
will be extended to build the package optimised for speed. In short this where speed is of paramount importance, and will use-03
by default.
insecure_build
If this file exists, the
CFLAGS/LDFLAGS
will be replaced, using the smallest-02
based generic flags possible. This is useful for operating systems employing heavy optimisations or full RELRO by default.
autospec
will attempt to use a number of patterns to determine the name and version of the package by examining the URL. For most tarballs this is simple, if they are of the format $name-$version.tar.$compression
.
For websites such as bitbucket
or GitHub
, using get$
and v$.tar.*
style links, the project name itself is used from the URL and the version is determined by stripping down the tag.
CPAN Perl packages, R packages, and rubygems.org rubygems are automatically prefixed with their language name: perl-
, R-
and rubygem-
respectively.
When these automated detections are not desirable, it is possible to override these with the --name
flag when invoking autospec
autospec
can optionally talk to a license server instead of checking local hashsum files, which enables greater coverage for license detection. The URL set in license_fetch
is expected to be a simple script that talks HTTP.
This URL should accept POST
requests with the following keys:
- hash
Contains the SHA-1 hash of the potential license file being checked.
- package
The name of the package being examined
- text
The contents of the potential license file
Implementations return a plain text response with the SPDX identifier of the license, if known. An empty response is assumed to mean that this license is unknown, in which case autospec
will emit the license_show
URL. The implementation should show the now-stored license file via a web page, and enable a human to make a decision on the license. This is then stored internally, allowing future requests to automatically know the license type when this hash is encounted again.
