RPM packaging automation tool
======== Autospec
autospec is a tool to assist in the automated creation and maintenance 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.

Configuration of autospec
autospec is configured by means of a simple INI-style configuration file.
The default location of this file is assumed to be
/usr/share/defaults/autospec/autospec.conf
.
Example autospec.conf
file::
[autospec]
git = [email protected]/%(NAME)s
license_fetch = http://yourhost/hash.php
license_show = http://yourhost/showone.php?hash=%(HASH)s
packages_file = file:///path/to/package_list_file
yum_conf = file:///path/to/yum.conf
upstream = http://yourhost/tarballs/%(HASH)s/%(NAME)s
git Optional URI template for remote git repository
license_fetch Optional URL to use for scanning license files
license_show Optional URL to interact with online license checker
packages_file Optional path to add autodetected runtime requirement checking
yum_conf Optional path to yum configuration
upstream Base URL for stored upstream tarballs

Requirements
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 it will use the
autospec/license_hashes
file - which is a 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
Control files
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.
Common files
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 $package
in the filename with the actual package name.
Controlling dependencies
buildreq_add
Each line in the file provides the name of a package to add as a build
dependency to the .spec
.
pkgconfig_add
Each line in the file is assumed to be a pkgconfig() build dependency. Add
the pkg-config names here, as autospec
will automatically transform the
names into their pkgconfig($name)
style when generating the .spec
.
requires_add
Each line in the file provides the name of a package to add as a runtime
dependency to the .spec
.
${custom}_requires_add
Same as "requires_add" above, but instead of the Requires being placed on the
main
subpackage, they will be placed on the -${custom}
subpackage.
provides_add
Each line in the file provides the name of a identifier to add as a Provides
to the .spec
.
${custom}_provides_add
Same as "provides_add" above, but instead of the Provides being placed on the
main
subpackage, they will be placed on the -${custom}
subpackage.
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 with
pkgconfig_add
, these names are automatically transformed by autospec
into their correct pkgconfig($name))
style.
requires_ban Each line in the file is a runtime dependency that under no circumstance should be automatically added to the runtime dependencies. This is useful to block automatic configuration routines adding undesired functionality, or to omit any automatically discovered dependencies during tarball scanning.
${custom}_requires_ban
Same as "requires_ban" above, but instead of the Requires being removed from
the main
subpackage, they will be removed from the -${custom}
subpackage.
provides_ban Each line in the file is an identifier that under no circumstance should be automatically added as a Provides. This is useful to block automatic configuration routines adding undesired identifiers.
${custom}_provides_ban
Same as "provides_ban" above, but instead of the Provides being removed from
the main
subpackage, they will be removed from the -${custom}
subpackage.
.. note::
Run time requirements are not assumed to be build time requirement If a package has the same build and run time requirement it must be added to both buildreq_add and requires_add.
Controlling the build process
extra_sources
This file contains a list of extra files to be added to the .spec
and
optionally installed as well. Each non-blank and non-comment line should start
with the file name as found in the Git directory, followed by arguments to be
passed to the /usr/bin/install(3) command, with at least one argument starting
with a slash, denoting the destination directory (there's no need for
%{buildroot}
). If the install arguments are missing, Autospec will not
generate an installation command and the package should specify how to install
in the install_append file (see below).
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
.
configure_openmpi
This file contains configuration flags to pass to the %configure
macro for
autotools based tarballs to configure openmpi builds.
configure32, configure64, configure_avx2, configure_avx512
These files are appended to the %configure'' macro after the contents of the
configure'' file above. They are used for 32-bit,
regular 64-bit, AVX2 and AVX512 builds, respectively.
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
.
cmake_args_openmpi
This file contains arguments that should be passed to the %cmake
macro for
CMake based tarballs for openmpi builds.
make_command
The contents of this file will be used instead of the make
command, i.e. use this if make
should be replace with another build tool
like ninja
.
make_args
The contents of this file are appended to the make
invocation. This may be
useful for passing arguments to make
, i.e. make TOOLDIR=/usr
make32_args
The contents of this file are appended to the make
invocation of the 32bit
build. It is appended after the make_args content so 32bit specific overrides
can be added.
make_install_args
Much like make_args
, this will pass arguments to the make install
macro in the .spec
make32_install_args
Much like make32_args
, this will pass arguments to the make install
macro in the .spec
for the 32bit build. Again it is appended after
make_install_args so 32bit specific overrides can be added.
prep_prepend
Additional actions that should take place directly after %prep
and before the %setup
macro. This will be placed in the
resulting .spec
, and is used for situations where fine-grained
control is required.
build_prepend
Additional actions that should take place after %build
and before
the %configure
macro or equivalent (%cmake
, etc.). If autospec
is creating AVX2, AVX-512 or 32-bit, these actions will be repeated for
each of those builds, This will be placed in the resulting .spec
,
and is used for situations where fine-grained control is required.
build_prepend_once
Additional actions that should take place directly after %build
and before the %configure
macro or equivalent (%cmake
, etc.).
If autospec is creating AVX2, AVX-512 or 32-bit, these action will
not be repeated for each of those builds, This will be placed in the
resulting .spec
, and is used for situations where fine-grained
control is required.
make_prepend
Additional actions that should take place directly after the
configuring step and before the %make
macro or equivalent. If
autospec is creating AVX2, AVX-512 or 32-bit, these actions will be
repeated for each of those builds, before their respective make
steps. This will be placed in the resulting .spec
, and is used
for situations where fine-grained control is required.
install_prepend
Additional actions that should take place directly after
%install
but before the %make_install
macro (or equivalent).
This will be placed in the resulting .spec
, and is used for
situations where fine-grained control is required.
install_append
Additional actions that should take place at the very end of the
%install
section. This will be placed in the resulting .spec
,
and is used for situations where fine-grained control is required.
install_macro
The contents of this file will 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 the unix
subdirectory. Set the name in this file and the
.spec
will emit the correct pushd
and popd
lines to utilise these
directories for each step in the build.
cmake_srcdir The contents of this file are a path to the source directory in which to run cmake for non-standard packages. This path is relative to the clr-build subdirectory, which is created directly below the source package's root.
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:
- R: R language package
- cpan: perl language package
- ruby: ruby language package
- configure: Traditional
%configure
autotools route - configure_ac: Like
configure
, but performs%reconfigure
to regenerate./configure
- autogen: Similar to
configure_ac
but uses the existing./autogen.sh
instead of%reconfigure
- cmake: Traditional builds using CMake
- qmake: qmake (Qt5) projects
- make: Run
make
followed bymake install
, skipping configure. Note that this is the fallback build pattern in case no other build patterns are autodetected - distutils3: Only build the Pythonic package with Python 3
- pyproject: Build the Pythonic package using the PEP 516 method
- meson: Build package with Meson/Ninja
- golang: Build Go package
- godep: A go dependency-only package
- [WIP] cargo: Build Rust package with Cargo
- [WIP] scons: Build package with Scons
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.
Arguments to patch can be added after the patch filename. For example:
0001-my-awesome-patch.patch -d some/subdir -p1
pypi_overrides This file contains a list of modules to remove version tests on during the build. It also modifies the requirement of the requires.txt egg if it exists in the package. For example:
colorama
in the file will cause this modification:
- 'colorama>=0.2.5,<0.4.4',
+ 'colorama',
golang_libpath
When building go packages, the go import path will be guessed automatically
(e.g. building https://github.com/go-yaml/yaml/
would get
github.com/go-yaml/yaml
). While this is handy, it's not always correct (in
the previous example, the correct import path should be gopkg.in/yaml.v2
).
This could be easily fixed by placing gopkg.in/yaml.v
in this file,
changing where the go bits will be placed.
service_restart Each line in the file specifies the full path to a systemd unit file installed by this package that should be restarted by clr-service-restart_.
.. _clr-service-restart: https://github.com/clearlinux/clr-service-restart
Controlling files and subpackages
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.
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.
dev_extras
Same as "extras" above, but instead of the files being placed in an
-extras
subpackage, they will be placed in the -dev
one. Use this
functionality to place files used only for development against this
software that Autospec does not automatically detect.
tests_extras
Same as "extras" above, but instead of the files being placed in an
-extras
subpackage, they will be placed in the -tests
one. Use this
functionality to place files used only for testing against this
software that Autospec does not automatically detect.
${custom}_extras
Same as "extras" above, but instead of the files being placed in an
-extras
subpackage, they will be placed in the extras-${custom}
subpackage.
${custom}_extras_requires
Each line contains a subpackage names of other subpackages in the package.
This is used when the extras-${custom}
subpackage has a runtime
requirement on a sibling subpackage.
An example of the ${custom}_extras
and ${custom}_extras_requires
being used together with::
/usr/bin/foo
in foo_extras and::
data
in foo_extras_requires will produce a spec file package section for example-foo-extras with the following content::
%package extras-foo
Summary: extras-foo components for the example package.
Group: Default
Requires: example-data = %{version}-%{release}
%description extras-foo
extras-foo components for the example package.
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 specify mode, user, group and filename
(space separated) which is translated into 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.
An example of a attrs
file would contain::
4755 root messagebus /usr/libexec/dbus-daemon-launch-helper
which would translate to the following line in the resulting .spec
file::
%attr(4755,root,messagebus) /usr/libexec/dbus-daemon-launch-helper
Controlling test suites
By default, autospec
will attempt to detect potential test suites that
can be run in the %check
portion of the .spec
.
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.
Controlling miscellaneous spec metadata
description Provides content for the %description section, overriding the content autospec autodetects. This is useful if autospec cannot find proper content for the description, if one wants to customize the content for better presentation, etc.
summary
Provides the main Summary: value of the package, overriding any automatically found values. Only the first line is used.
pypi.json Provides an alternative to reading the pypi api url for package metadata. provides, requires, summary, description and license information could be sourced from this file (see https://wiki.python.org/moin/PyPIJSON) for more details on the structure.
Controlling flags and optimization
Further control of the build can be achieved through the use of the
options.conf
file. If this file does not exist it is created by autospec
with default values. If certain deprecated configuration files exists autospec
will use the value indicated by those files and remove them.
The options that can be set in options.conf
are as follows:
asneeded
If this is option set, 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 option is set, the CFLAGS/LDFLAGS
will be extended to build the
package optimized for size, and not for speed. Use this when size is more
critical than performance.
funroll-loops
If this option is set, the CFLAGS/LDFLAGS
will be extended to build the
package optimized for speed. In short this where speed is of paramount
importance, and will use -03
by default.
insecure_build
If this option is set, the CFLAGS/LDFLAGS
will be replaced, using the
smallest -02
based generic flags possible. This is useful for operating
systems employing heavy optimizations or full RELRO by default.
pgo
If this option is set, the CFLAGS/CXXFLAGS
will be extended to build the
package with profile-guided optimization data. It will add -O3
,
-fprofile-use
, -fprofile-correction
and -fprofile-dir=pgo
.
use_lto If this option is set, link time optimization is enabled for the build.
use_avx2 If this option is set, a second set of libraries, for AVX2, is built.
use_avx512 If this option is set, an additional set of libraries, for AVX512, is built.
openmpi If this option is set, an additional openmpi package is built.
fast-math If this option is set, -ffast-math is passed to the compiler.
broken_c++ If this option is set, flags are extended with -std=gnu++98.
allow_test_failures
If this option is set it will allow test failures, and will still emit the
%check
code in a way that allows the build to continue.
skip_tests If this option is set the test suite will not be run.
no_autostart If this option is set the autostart subpackage (which contains all files matching /usr/lib/systemd/system/*.target.wants/) will not be required by the base package.
conservative_flags If this option is set autospec will set conservative build flags
broken_parallel_build If this option is set, the parallelization is disabled during build.
use_clang If this option is set autospec will utilize clang. This unsets the funroll-loops optimization if it is set.
keepstatic
If this option is set, then %define keepstatic 1
is emitted in the
.spec
. As a result, any static archive (.a
) files will not be removed
by rpmbuild.
32bit This option will trigger the creation of 32-bit libraries for a 32-bit build.
nostrip This option will suppress the stripping of the created binaries.
verify_required This option will make package verification required for the build. This option is automatically set if package verification is ever successful, but can be turned off manually.
security_sensitive This options sets flags for security-sensitive builds.
so_to_lib
This option causes package .so
files to be added to the lib
subpackage
instead of the dev
subpackage.
dev_requires_extras
If this option is set, the extras
subpackage is marked as a dependency of
the dev
package.
autoupdate
This option indicates that the package is trusted enough to be automatically
update to its newest available version when set to true
. This flag is
intended to be used by tools running autospec automatically.
compat This option indicates the package is a library compatibility package and only provides versioned library files.
nodebug
If this option is set, debuginfo
is not created for this package.
Name and version resolution
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
Automatic license server support
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 encountered again.
Integration of systemd unit files
autospec
can add most systemd template file types by having a file in the
filename.extension in the build directory. Supported extensions are:
mount, service, socket, target, timer, path and tmpfiles
. The files will
be added as Source# entries and be installed to their appropriate system
location.
