NAME
piuparts - .deb installation, upgrade, and removal testing suite
SYNOPSIS
piuparts [-apvV] [-d distro] [-i filename] [-I regexp] [-l logfile] [-m url] [--bindmount dir]
[package]... [changes_file]...
DESCRIPTION
piuparts tests that Debian packages handle installation, upgrading, and removal correctly. It does this
by creating a minimal Debian installation in a chroot, and installing, upgrading, and removing packages
in that environment, and comparing the state of the directory tree before and after. piuparts reports any
files that have been added, removed, or modified during this process.
piuparts is meant as a quality assurance tool for people who create Debian packages to test them before
they upload them to the Debian package archive.
By default, piuparts can do three different tests:
1. A simple install-purge test within one Debian distribution (chosen with the -d option, unstable by
default). It sets up the chroot with the desired distribution, then installs and purges the packages,
and reports problems.
2. A simple install-upgrade-purge test within one Debian distribution. This test is like the
install-purge test, but it installs the packages first via apt-get and then from the package files
given on the command line. If the command line has package names (option --apt used), or no tested
package is known to apt-get (new packages), this test is skipped, otherwise it is performed
automatically.
3. An upgrade test between Debian releases. This test is enabled by using the -d option multiple times
and disables the other two tests. It sets up the chroot with the first distribution named, then
upgrades it to each successive one, and then remembers the directory tree state at the end. After
this, it starts over with the chroot of the first distribution, installs the desired packages (via
apt-get), and does the successive upgrading (via apt-get dist-upgrade). Then, if package files (and
not just package names) were given on the command line, it installs them. Finally, it reports
problems against the state of the directory tree at the last distribution compared with the state
without the packages having been installed. This test can be quite slow to execute.
Note that this does not work with experimental, because apt-get does not automatically upgrade to
packages in experimental. To test a particular package or group of packages in experimental, use the
second test.
Command line arguments are the paths to package files (e.g., piuparts_1.0-1_all.deb), paths to changes
files (e.g., piuparts_1.0-1_i386.changes), or names of packages, if the --apt option is given.
When processing changes files, by default, all packages in a changes file will be processed together with
all individual packages given on the command line. Then each package given on the command line is
processed in a single group. If the --single-changes-list is used, the packages in all changes files are
processed together along with any individual packages that were given on the command line. To avoid this
behaviour, it is possible to specify --single-packages.
piuparts outputs to the standard output some log messages to show what is going on. If a log file is
used, the messages go there as well.
piuparts needs to be run as root.
OPTIONS
Options must come before the other command line arguments.
-a, --apt
The package arguments on the command line are to be treated as package names and installed via
apt-get instead of being names of package files, to be installed via dpkg -i.
--allow-database
Allow starting MySQL and PostgreSQL database servers in the chroot for packages requiring database
access in their maintainer scripts. Do not use this option if there is already a database server
running on the system running piuparts (or piuparts-slave)! In master-slave setups with multiple
slaves running on one host collisions may occur, these will be detected by detect_piuparts_issues and
the affected packages will be tested again.
--arch=arch
Create chroot and run tests for (non-default) architecture arch. The default is the output from dpkg
--print-architecture.
-b tarball, --basetgz=tarball
Use tarball as the contents of the initial chroot, instead of building a new one with debootstrap.
The tarball can be created with the -s option, or you can use one that pbuilder has created (see -p).
If you create one manually, make sure the root of the chroot is the root of the tarball.
--bindmount=dir
Bind-mount a directory inside the chroot.
-d name, --distribution=name
Which Debian distribution to use: a code name (for example jessie, stretch or sid) or experimental.
The default is sid (=unstable).
-D flavor, --defaults=flavor
Use default settings suitable for a particular flavor of Debian: either debian or ubuntu. The default
is debian.
--do-not-verify-signatures
Do not verify signatures from the Release files when running debootstrap. Also set
APT::Get::AllowUnauthenticated accordingly in /etc/apt/apt.conf in the chroots.
--dpkg-force-confdef
Make dpkg use --force-confdef, which lets dpkg always choose the default action when a modified
conffile is found. This option will make piuparts ignore errors it was designed to report and
therefore should only be used to hide problems in depending packages. This option shall normally not
be used. (See #466118.)
--dpkg-noforce-unsafe-io
Prevent running dpkg with --force-unsafe-io. --force-unsafe-io causes dpkg to skip certain file
system syncs known to cause substantial performance degradation on some filesystems. Thus, including
this option reverts to safe but slower behavior. The --dpkg-noforce-unsafe-io is required for running
tests on distributions older than squeeze.
--no-eatmydata
Prevent use of eatmydata. The --no-eatmydata option is required for running tests on squeeze or older
distributions.
--extra-old-packages=pkg1[,pkg2]...
Install additional old packages before upgrading. Allows testing package renames/merges where the old
package is no longer available in the new distribution and the new one utilizes Conflicts/Replaces.
The argument is a comma separated list of package names and the option can be given multiple times.
For install/purge tests these packages will be installed before the package that is to be tested.
-e dirname, --existing-chroot=dirname
Use the specified directory as source for the new chroot, instead of building a new one with
debootstrap. This is similar to --basetgz, but the contents are not archived. See also the
--hard-link option.
--distupgrade-to-testdebs
Use the "testdebs" repository to override the packages in the distupgrade target distribution. This
allows one to test complex upgrade paths before the packages enter the archive.
--extra-repo=deb-line
Provide an additional (unparsed) line to be appended to sources.list, e.g. deb <URL> <distrib>
<components> or deb file:// </bind/mount> ./ Useful for e.g. backports, security or local
repositories that cannot be handled by --mirror. May be repeated to add more than one line.
--fake-essential-packages=pkg1[,pkg2]...
Install additional packages in the base chroot that are not removed after the test. These are
available during purge and for checking against mistreatment. Takes a comma separated list of package
names and can be given multiple times.
--hard-link
When the --existing-chroot option is used, and the source directory is on the same filesystem,
hard-link files instead of copying them. This is faster, but any modifications to files will be
reflected in the originals.
-i filename, --ignore=filename
Add a filename to the list of filenames to be ignored when comparing changes before and after
installation. By default, piuparts ignores files that always change during a package installation and
uninstallation, such as dpkg status files. The filename should be relative to the root of the chroot
(e.g., var/lib/dpkg/status). Filenames prefixed with a : will be logged verbosely if found. This
option can be used as many times as necessary.
-I regexp, --ignore-regexp=regexp
Add a regular expression pattern to the list of patterns for filenames to be ignored when comparing
changes before and after installation. Patterns prefixed with a : will log verbosely all matching
files. This option can be used as many times as necessary.
--install-purge-install
Purge package after installation and reinstall. All dependencies are available during purge.
--install-recommends
Enable installation of Recommends.
--install-suggests
Enable installation of Suggests.
--install-remove-install
Remove package after installation and reinstall. For testing installation in config-files-remaining
state.
-k, --keep-tmpdir
Don’t remove the temporary directory for the chroot when the program ends.
-K, --keyring=filename
Use FILE as the keyring to use with debootstrap when creating chroots.
--keep-sources-list
Don’t modify the chroot’s etc/apt/sources.list.
--list-installed-files
List the files added to the chroot after the installation of the package and after the installation
of the package dependencies.
--lvm-volume=lvm-volume
Use the specified lvm-volume as source for the chroot, instead of building a new one with
debootstrap. This creates a snapshot of the given LVM volume and mounts it to the chroot path.
--lvm-snapshot-size=snapshot-size
Use the specified snapshot-size as snapshot size when creating a new LVM snapshot (default: 1G)
-l filename, --log-file=filename
Append log file to filename in addition to the standard output.
--log-level=level
Display messages from loglevel LEVEL, possible values are: error, info, dump, debug. The default is
dump.
-m url, --mirror=url
Which Debian mirror to use. The default is the first mirror named in /etc/apt/sources.list or
http://deb.debian.org/debian if none is found. This option may be used multiple times to use multiple
mirrors. Only the first mirror is used with debootstrap.
The components that are used for a mirror can also be set with this option: a space separated list
within the same argument (so you need to quote the entire argument in the shell). If no components
are given explicitly, the usual Debian components are used (main, contrib, and non-free). For the
mirrors read from /etc/apt/sources.list, the components are read from the same place.
Note that file: addresses works if the directories are made accessible from within the chroot with
--bindmount.
--no-adequate
Don’t run adequate after installation. The default is to run adequate, provided it is installed.
--no-check-valid-until
Set apt option Acquire::Check-Valid-Until=false in the chroot to ignore the expiration of Release
files. This is needed for testing archived releases.
--no-diversions
Don’t check for broken diversions.
-n, --no-ignores
Forget all built-in and other ignores that have been set so far. Any -i or -I arguments that come
after this one will be obeyed, but none of the ones that come before.
-N, --no-symlinks
Don’t check for broken symlinks.
--fail-if-inadequate
Fail on inadequate results from running adequate. The default is to just issue those errors as
warnings.
--fail-on-broken-symlinks
Fail on broken symlinks. The default is to just issue those errors as warnings.
--no-upgrade-test
Skip testing upgrade from an existing version in the archive.
--no-install-purge-test
Skip the install and purge test.
-p, *--pbuilder
Use /var/cache/pbuilder/base.tgz as the base tarball. This is a shorthand so that you don’t need to
use -b for it.
--pedantic-purge-test
Be pedantic when checking if a purged package leaves files behind. If this option is not set, files
left in /tmp are ignored.")
--proxy=URL
Use the proxy at URL to access the Debian mirror(s). Takes precedence over the http_proxy environment
variable. Using a local proxy is recommended because piuparts may use large amounts of bandwidth to
repeatedly download the same files.
-s filename, --save=filename
Save the chroot, after it has been set up, as a tarball into filename. It can then be used with -b.
-B FILE, --end-meta=FILE
Load chroot package selection and file meta data from FILE. See the function
install_and_upgrade_between_distros() in piuparts.py for defaults. Mostly useful for large scale
distro upgrade tests.
-S FILE, --save-end-meta=FILE
Save chroot package selection and file meta data in FILE for later use. See the function
install_and_upgrade_between_distros() in piuparts.py for defaults. Mostly useful for large scale
distro upgrade tests.
--scriptsdir=DIR
Directory where are custom scripts are placed. By default, this is not set. For more information
about this, read README_server.txt
--schroot=SCHROOT-NAME
Use schroot session named SCHROOT-NAME for the chroot, instead of building a new one with
debootstrap.
--single-changes-list
When processing changes files, piuparts will process the packages in each individual changes file
seperately. This option will set piuparts to scan the packages of all changes files together along
with any individual package files that may have been given on the command line.
--single-packages
Process every package file or package name individually, thus piuparts process runs multiple times.
This option can be useful with conflicting packages.
--shell-on-error
Start an interactive shell in the chroot after an error occurred. This should help debugging failures
directly inside the piuparts test environment. The chroot cleanup will continue after the shell
terminates. Note: This does not work if the piuparts command is prefixed with timeout, which is
usually the case in command lines directly copied from logfiles from a master-slave setup. Removing
the timeout part is sufficient.
--skip-minimize
Allow skip minimize chroot step. This is useful when you want to test several packages with piuparts.
You can prepare a tarball already minimized and skip this step in all the tests. This is the default
now.
--minimize
Minimize the chroot with debfoster. This used to be the default until #539142 was fixed.
--skip-cronfiles-test
Skip testing the output from the cron files left in the system after remove a package.
--skip-logrotatefiles-test
Skip testing the output from the logrotate files left in the system after remove a package.
--testdebs-repo=deb-line
Provide an additional line to be appended to sources.list, e.g. deb [ trusted=yes ] <URL> <distrib>
<components> or deb [ trusted=yes ] file:// </bind/mount> ./ If only an URL or local path is given as
argument, "deb [ trusted=yes ]", "file://", and "./" will be prepended/appended as needed. The
"testdebs" repository provides the packages to be tested (and some additional dependencies, if
needed, e.g. all packages built from the same source package as the (binary) package being tested)
and can be used for testing complex installation and upgrade scenarios involving dependencies that
are not yet in the archive. This repository will be available only for installing the target
packages. Dependency resolution will be done by apt-get. The packages to be tested can be passed as
.debs or as package names (with --apt). The "trusted=yes" option causes this (and only this)
repository to be trustworthy even if the Packages file is not signed, such that a (globally acting)
--do-not-verify-signatures will not be needed.
-t directory, --tmpdir=directory
Use directory as the place where temporary files and directories are created. The default is the
environment variable TMPDIR, or /tmp if not set.
Note: the temporary directory must not be mounted with the nodev or nosuid mount option.
--upgrade-before-dist-upgrade
Perform two-stage upgrades: apt-get upgrade && apt-get dist-upgrade.
-v, --verbose
This option no longer has any meaning, but it is still accepted for backwards compatibility.
-V, --version
Write out the version number of the program.
--warn-on-debsums-errors
Print a warning rather than failing if debsums reports modified files.
--warn-on-leftovers-after-purge
Print a warning rather than failing if files are left behind after purge.
--warn-on-others
Print a warning rather than failing if files are left behind, modified, or removed by a package that
was not given on the command-line.
This way, you can basically isolate the purge test to your own packages. If a package that is brought
in as a dependency doesn’t purge cleanly, the test will not fail because of it (but a warning message
will be printed).
Behavior with multiple packages given on the command-line could be problematic, particularly if the
dependency tree of one package in the list includes another in the list. Therefore, it is recommended
to use this option with one package at a time.
EXAMPLES
Assume that you have just built a new version of your Debian package, to be uploaded to Debian unstable.
It is in ../foo_1.0-2_i386.deb and you would like to know whether it installs and uninstalls properly.
Here’s what you would do:
piuparts ../foo_1.0-2_i386.deb
If the package exists in the Debian archive already, the above command also tests that it upgrades
properly.
To do the same test, but using a particular mirror, and only the main component, you would do this:
piuparts -m 'http://gytha/debian main' ../foo_1.0-2_i386.deb
If you want to do the same as above but for your changes files, pass in your changes files when running
piuparts, and piuparts will process each package in the changes files as though you had passed all those
packages on the command line to piuparts yourself. For example:
piuparts ../foo_1.0-2_i386.changes
piuparts -m 'http://gytha/debian main' ../foo_1.0-2_i386.changes
If you want to test that a package installs properly in the stable (currently jessie) Debian release,
then can be upgraded to the testing (currently stretch) and unstable (sid) versions, and then uninstalled
without problems, you would give the following command:
piuparts -a -d jessie -d stretch -d sid foo
ENVIRONMENT
TMPDIR Location for temporary files and directories. If not set, use /tmp. See also the -t (--tmpdir)
option.
NOTES
Output of commands run by piuparts is limited to three megabytes. To change this limit, the source code
needs to be edited. Commands exceeding this limit will be aborted.
