= Introduction =
|
|
|
|
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 always be 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 RCBugPolicy.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 AgePolicy._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 packages and updated
|
|
binary packages (binNMU), excluding the architecture-independent
|
|
ones, and 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. If the suite is unstable, 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 one 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. Unless
|
|
a `force' hint exists, the new package must also be available
|
|
on all of the architectures for which it has binary packages in
|
|
testing.
|
|
|
|
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 of the excuses depending on them are
|
|
marked as invalid "impossible dependencies".
|
|
|
|
* The excuses are written in an HTML file.

This method will compute the binaries that will be added,

|
Parameters:
|
|
* "source_name" is the name of the source package, whose
|
|
binaries are migrating.
|
|
* "suite" is the suite from which the binaries are migrating.
|
|
[Same as item.suite, where available]
|
|
* "migration_architecture" is the architecture determines
|
|
architecture of the migrating binaries (can be "source" for
|
|
a "source"-migration, meaning all binaries regardless of
|
|
architecture). [Same as item.architecture, where available]
|
|
* "is_removal" is a boolean determining if this is a removal
|
|
or not [Same as item.is_removal, where available]
|
|
* "allow_smooth_updates" is a boolean determing whether smooth-
|
|
updates are permitted in this migration. When set to False,
|
|
the "smoothbins" return value will always be the empty set.
|
|
Any value that would have been there will now be in "rms"
|
|
instead. (defaults: True)
|
|
* "removals" is a set of binaries that is assumed to be
|
|
removed at the same time as this migration (e.g. in the same
|
|
"easy"-hint). This may affect what if some binaries are
|
|
smooth updated or not. (defaults: empty-set)
|
|
- Binaries must be given as ("package-name", "version",
|
|
"architecture") tuples.
|
|
|
|
Returns a tuple (adds, rms, smoothbins). "adds" is a set of
|
|
binaries that will updated in or appear after the migration.
|
|
"rms" is a set of binaries that are not smooth-updatable (or
|
|
binaries that could be, but there is no reason to let them be
|
|
smooth updated). "smoothbins" is set of binaries that are to
|
|
be smooth-updated.
|
|
|
|
Each "binary" in "adds", "rms" and "smoothbins" will be a
|
|
tuple of ("package-name", "version", "architecture") and are
|
|
thus tuples suitable for passing on to the
|
|
InstallabilityTester.

any other package (in terms of excuses), a list of dependencies and

Once all such lists have been generated, any which are subsets of other

lists are ignored in favour of the larger lists. The remaining lists are

We also try to auto hint circular dependencies analyzing the update

excuses relationships. If they build a circular dependency, which we already

know as not-working with the standard do_all algorithm, try to `easy` them.
