= Introdution =
|
|
|
|
This is the Debian testing updater script, also known as "Britney".
|
|
|
|
Packages are usually installed into the `testing' distribution after
|
|
they have undergone some degree of testing in unstable. The goal of
|
|
this software is to do this task in a smart way, allowing testing
|
|
to be always fully installable and close to being a release candidate.
|
|
|
|
Britney's source code is split between two different but related tasks:
|
|
the first one is the generation of the update excuses, while the
|
|
second tries to update testing with the valid candidates; first
|
|
each package alone, then larger and even larger sets of packages
|
|
together. Each try is accepted if testing is not more uninstallable
|
|
after the update than before.
|
|
|
|
= Data Loading =
|
|
|
|
In order to analyze the entire Debian distribution, Britney needs to
|
|
load in memory the whole archive: this means more than 10.000 packages
|
|
for twelve architectures, as well as the dependency interconnections
|
|
between them. For this reason, the memory requirements for running this
|
|
software are quite high and at least 1 gigabyte of RAM should be available.
|
|
|
|
Britney loads the source packages from the `Sources' file and the binary
|
|
packages from the `Packages_${arch}' files, where ${arch} is substituted
|
|
with the supported architectures. While loading the data, the software
|
|
analyzes the dependencies and builds a directed weighted graph in memory
|
|
with all the interconnections between the packages (see Britney.read_sources
|
|
and Britney.read_binaries).
|
|
|
|
Other than source and binary packages, Britney loads the following data:
|
|
|
|
* BugsV, which contains the list of release-critical bugs for a given
|
|
version of a source or binary package (see Britney.read_bugs).
|
|
|
|
* Dates, which contains the date of the upload of a given version
|
|
of a source package (see Britney.read_dates).
|
|
|
|
* Urgencies, which contains the urgency of the upload of a given
|
|
version of a source package (see Britney.read_urgencies).
|
|
|
|
* Hints, which contains lists of commands which modify the standard behaviour
|
|
of Britney (see Britney.read_hints).
|
|
|
|
For a more detailed explanation about the format of these files, please read
|
|
the documentation of the related methods. The exact meaning of them will be
|
|
instead explained in the chapter "Excuses Generation".
|
|
|
|
= Excuses =
|
|
|
|
An excuse is a detailed explanation of why a package can or cannot
|
|
be updated in the testing distribution from a newer package in
|
|
another distribution (like for example unstable). The main purpose
|
|
of the excuses is to be written in an HTML file which will be
|
|
published over HTTP. The maintainers will be able to parse it manually
|
|
or automatically to find the explanation of why their packages have
|
|
been updated or not.
|
|
|
|
== Excuses generation ==
|
|
|
|
These are the steps (with references to method names) that Britney
|
|
does for the generation of the update excuses.
|
|
|
|
* If a source package is available in testing but it is not
|
|
present in unstable and no binary packages in unstable are
|
|
built from it, then it is marked for removal.
|
|
|
|
* Every source package in unstable and testing-proposed-updates,
|
|
if already present in testing, is checked for binary-NMUs, new
|
|
or dropped binary packages in all the supported architectures
|
|
(see Britney.should_upgrade_srcarch). The steps to detect if an
|
|
upgrade is needed are:
|
|
|
|
1. If there is a `remove' hint for the source package, the package
|
|
is ignored: it will be removed and not updated.
|
|
|
|
2. For every binary package built from the new source, it checks
|
|
for unsatisfied dependencies, new binary package and updated
|
|
binary package (binNMU) excluding the architecture-independent
|
|
ones and the packages not built from the same source.
|
|
|
|
3. For every binary package built from the old source, it checks
|
|
if it is still built from the new source; if this is not true
|
|
and the package is not architecture-independent, the script
|
|
removes it from testing.
|
|
|
|
4. Finally, if there is something worth doing (eg. a new or updated
|
|
binary package) and nothing wrong it marks the source package
|
|
as "Valid candidate", or "Not considered" if there is something
|
|
wrong which prevented the update.
|
|
|
|
* Every source package in unstable and testing-proposed-updates is
|
|
checked for upgrade (see Britney.should_upgrade_src). The steps
|
|
to detect if an upgrade is needed are:
|
|
|
|
1. If the source package in testing is more recent the new one
|
|
is ignored.
|
|
|
|
2. If the source package doesn't exist (is fake), which means that
|
|
a binary package refers to it but it is not present in the
|
|
`Sources' file, the new one is ignored.
|
|
|
|
3. If the package doesn't exist in testing, the urgency of the
|
|
upload is ignored and set to the default (actually `low').
|
|
|
|
4. If there is a `remove' hint for the source package, the package
|
|
is ignored: it will be removed and not updated.
|
|
|
|
5. If there is a `block' hint for the source package without an
|
|
`unblock` hint or a `block-all source`, the package is ignored.
|
|
|
|
6. If there is a `block-udeb' hint for the source package, it will
|
|
have the same effect as `block', but may only be cancelled by
|
|
a subsequent `unblock-udeb' hint.
|
|
|
|
7. If the suite is unstable, the update can go ahead only if the
|
|
upload happened more than the minimum days specified by the
|
|
urgency of the upload; if this is not true, the package is
|
|
ignored as `too-young'. Note that the urgency is sticky, meaning
|
|
that the highest urgency uploaded since the previous testing
|
|
transition is taken into account.
|
|
|
|
8. All the architecture-dependent binary packages and the
|
|
architecture-independent ones for the `nobreakall' architectures
|
|
have to be built from the source we are considering. If this is
|
|
not true, then these are called `out-of-date' architectures and
|
|
the package is ignored.
|
|
|
|
9. The source package must have at least a binary package, otherwise
|
|
it is ignored.
|
|
|
|
10. If the suite is unstable, the new source package must have no
|
|
release critical bugs which do not also apply to the testing
|
|
one. If this is not true, the package is ignored as `buggy'.
|
|
|
|
11. If there is a `force' hint for the source package, then it is
|
|
updated even if it is marked as ignored from the previous steps.
|
|
|
|
12. If the suite is testing-proposed-updates, the source package can
|
|
be updated only if there is an explicit approval for it.
|
|
|
|
13. If the package will be ignored, mark it as "Valid candidate",
|
|
otherwise mark it as "Not considered".
|
|
|
|
* The list of `remove' hints is processed: if the requested source
|
|
package is not already being updated or removed and the version
|
|
actually in testing is the same specified with the `remove' hint,
|
|
it is marked for removal.
|
|
|
|
* The excuses are sorted by the number of days from the last upload
|
|
(days-old) and by name.
|
|
|
|
* A list of unconsidered excuses (for which the package is not upgraded)
|
|
is built. Using this list, all the excuses depending on them is marked
|
|
as invalid for "unpossible dependency".
|
|
|
|
* The excuses are written in an HTML file.
