The Python deb822 aims to provide a dict-like interface to various RFC822-like
Debian data formats, like Packages/Sources, .changes/.dsc, pdiff Index files,
etc. As well as the generic :class:`Deb822` class, the specialised versions
of these classes (:class:`Packages`, :class:`Sources`, :class:`Changes` etc)
know about special fields that contain specially formatted data such as
dependency lists or whitespace separated sub-fields.
This module has few external dependencies, but can use python-apt if available
to parse the data, which gives a very significant performance boost when
iterating over big Packages files.
Whitespace separated data within fields are known as "multifields".
The "Files" field in Sources files, for instance, has three subfields, while
"Files" in .changes files, has five; the relevant classes here know this and
correctly handle these cases.
Key lookup in Deb822 objects and their multifields is case-insensitive, but
the original case is always preserved, for example when printing the object.
The Debian project and individual developers make extensive use of GPG
signatures including in-line signatures. GPG signatures are automatically
detected, verified and the payload then offered to the parser.
Relevant documentation on the Deb822 file formats available here.
- `deb-control(5)
<https://manpages.debian.org/unstable/dpkg-dev/deb-control.5.html>`_,
the `control` file in the binary package (generated from
`debian/control` in the source package)
- `deb-changes(5)
<https://manpages.debian.org/unstable/dpkg-dev/deb-changes.5.html>`_,
`changes` files that developers upload to add new packages to the
archive.
- `dsc(5) <https://manpages.debian.org/unstable/dpkg-dev/dsc.5.html>`_,
Debian Source Control file that defines the files that are part of a
source package.
- `Debian mirror format <http://wiki.debian.org/RepositoryFormat>`_,
including documentation for Packages, Sources files etc.
Overview of deb822 Classes
--------------------------
Classes that deb822 provides:
* :class:`Deb822` base class with no multifields. A Deb822 object holds a
single entry from a Deb822-style file, where paragraphs are separated by
blank lines and there may be many paragraphs within a file. The
:func:`~Deb822.iter_paragraphs` function yields paragraphs from a data
source.
* :class:`Packages` represents a Packages file from a Debian mirror.
It extends the Deb822 class by interpreting fields that
are package relationships (Depends, Recommends etc). Iteration is forced
through python-apt for performance and conformance.
* :class:`Dsc` represents .dsc files (Debian Source Control) that are the
metadata file of the source package.
Multivalued fields:
* Files: md5sum, size, name
* Checksums-Sha1: sha1, size, name
* Checksums-Sha256: sha256, size, name
* Checksums-Sha512: sha512, size, name
* Package-List: package, package-type, section, priority, _other
* :class:`Sources` represents a Sources file from a Debian mirror.
It extends the Dsc class by interpreting fields that
are package relationships (Build-Depends, Build-Conflicts etc).
Iteration is forced through python-apt for performance and conformance.
* :class:`Release` represents a Release file from a Debian mirror.
Multivalued fields:
* MD5Sum: md5sum, size, name
* SHA1: sha1, size, name
* SHA256: sha256, size, name
* SHA512: sha512, size, name
* :class:`Changes` represents a .changes file that is uploaded to "change
the archive" by including new source or binary packages.
Multivalued fields:
* Files: md5sum, size, section, priority, name
* Checksums-Sha1: sha1, size, name
* Checksums-Sha256: sha256, size, name
* Checksums-Sha512: sha512, size, name
* :class:`PdiffIndex` represents a pdiff Index file (`foo`.diff/Index) file
from a Debian mirror.
Multivalued fields:
* SHA1-Current: SHA1, size
* SHA1-History: SHA1, size, date
* SHA1-Patches: SHA1, size, date
* SHA1-Download: SHA1, size, filename
* X-Unmerged-SHA1-History: SHA1, size, date
* X-Unmerged-SHA1-Patches: SHA1, size, date
* X-Unmerged-SHA1-Download: SHA1, size, filename
* SHA256-Current: SHA256, size
* SHA256-History: SHA256, size, date
* SHA256-Patches: SHA256, size, date
* SHA256-Download: SHA256, size, filename
* X-Unmerged-SHA256-History: SHA256, size, date
* X-Unmerged-SHA256-Patches: SHA256, size, date
* X-Unmerged-SHA256-Download: SHA256, size, filename
* :class:`Removals` represents the ftp-master removals file listing when
and why source and binary packages are removed from the archive.
Input
=====
Deb822 objects are normally initialized from a file object (from which
at most one paragraph is read), a multiline string of Deb822 format, a
string representing a filename, or a pathlib.Path object.
Alternatively, any sequence that returns one line of input at a time
may be used, e.g a list of strings.
PGP signatures, if present, will be stripped.
Example::
>>> from debian.deb822 import Deb822
>>> filename = '/var/lib/apt/lists/deb.debian.org_debian_dists_sid_InRelease'
>>> with open(filename) as fh: # doctest: +SKIP
... rel = Deb822(fh)
>>> print('Origin: {Origin}\nCodename: {Codename}\nDate: {Date}'.format_map( # doctest: +SKIP
... rel))
Origin: Debian
Codename: sid
Date: Sat, 07 Apr 2018 14:41:12 UTC
>>> print(list(rel.keys())) # doctest: +SKIP
['Origin', 'Label', 'Suite', 'Codename', 'Changelogs', 'Date',
'Valid-Until', 'Acquire-By-Hash', 'Architectures', 'Components',
'Description', 'MD5Sum', 'SHA256']
In the above, the `MD5Sum` and `SHA256` fields are just a very long string. If
instead the :class:`Release` class is used, these fields are interpreted and
can be addressed::
>>> from debian.deb822 import Release
>>> filename = '/var/lib/apt/lists/deb.debian.org_debian_dists_sid_InRelease'
>>> with open(filename) as fh: # doctest: +SKIP
... rel = Release(fh)
>>> wanted = 'main/binary-amd64/Packages'
>>> [(l['sha256'], l['size']) for l in rel['SHA256'] if l['name'] == wanted] # doctest: +SKIP
[('c0f7aa0b92ebd6971c0b64f93f52a8b2e15b0b818413ca13438c50eb82586665', '45314424')]
Iteration
=========
All classes use the :func:`~Deb822.iter_paragraphs` class method to easily
iterate through each paragraph in a file that contains multiple entries
(e.g. a Packages.gz file).
For example::
>>> with open('/mirror/debian/dists/sid/main/binary-i386/Sources') as f: # doctest: +SKIP
... for src in Sources.iter_paragraphs(f):
... print(src['Package'], src['Version'])
The `iter_paragraphs` methods can use python-apt if available to parse
the data, since it significantly boosts performance.
If python-apt is not present and the
file is a compressed file, it must first be decompressed manually. Note that
python-apt should not be used on `debian/control` files since python-apt is
designed to be strict and fast while the syntax of `debian/control` is a
superset of what python-apt is designed to parse.
This function is overridden to force use of the
python-apt parser using `use_apt_pkg` in the :func:`~Packages.iter_paragraphs`
and :func:`~Sources.iter_paragraphs` functions.
Sample usage
============
Manipulating a .dsc file::
from debian import deb822
with open('foo_1.1.dsc') as f:
d = deb822.Dsc(f)
source = d['Source']
version = d['Version']
for f in d['Files']:
print('Name:', f['name'])
print('Size:', f['size'])
print('MD5sum:', f['md5sum'])
# If we like, we can change fields
d['Standards-Version'] = '3.7.2'
# And then dump the new contents
with open('foo_1.1.dsc2', 'w') as new_dsc:
d.dump(new_dsc)
(TODO: Improve, expand)

Deb822Dict behaves like a normal dict, except:
- key lookup is case-insensitive
- key order is preserved
- if initialized with a _parsed parameter, it will pull values from
that dictionary-like object as needed (rather than making a copy).
The _parsed dict is expected to be able to handle case-insensitive
keys.
If _parsed is not None, an optional _fields parameter specifies which keys
in the _parsed dictionary are exposed.

:param sequence: a string, or any object that returns a line of
input each time, normally a file. Or a filename (as a str) or a
`pathlib.Path` object. Alternately, sequence can
be a dict that contains the initial key-value pairs. When
python-apt is present, sequence can also be a compressed object,
for example a file object associated to something.gz.
:param fields: if given, it is interpreted as a list of fields that
should be parsed (the rest will be discarded).
:param _parsed: internal parameter.
:param encoding: When parsing strings, interpret them in this encoding.
(All values are given back as unicode objects, so an encoding is
necessary in order to properly interpret the strings.)
:param strict: Dict controlling the strictness of the internal parser
to permit tuning of its behaviour between "generous in what it
accepts" and "strict conformance". Known keys are described below.
*Internal parser tuning*
- `whitespace-separates-paragraphs`: (default: `True`)
Blank lines between paragraphs should not have any whitespace in them
at all. However:
- Policy §5.1 permits `debian/control` in source packages to separate
packages with lines containing whitespace to allow human edited
files to have stray whitespace. Failing to honour this breaks
tools such as
`wrap-and-sort <https://manpages.debian.org/wrap-and-sort>`_
(see, for example,
`Debian Bug 715558 <https://bugs.debian.org/715558/>`_).
- `apt_pkg.TagFile` accepts whitespace-only lines within the
`Description` field; strictly matching the behaviour of apt's
Deb822 parser requires setting this key to `False` (as is done
by default for :class:`Sources` and :class:`Packages`.
(see, for example,
`Debian Bug 913274 <https://bugs.debian.org/913274/>`_).
Note that these tuning parameter are only for the parser that is
internal to `Deb822` and do not apply to python-apt's apt_pkg.TagFile
parser which would normally be used for Packages and Sources files.

if available to parse the file, since it's much much faster. Set
this parameter to True to enable use of apt_pkg. Note that the
TagFile parser from apt_pkg is a much stricter parser of the
Deb822 format, particularly with regards whitespace between
paragraphs and comments within paragraphs. If these features are
required (for example in debian/control files), ensure that this
parameter is set to False.
:param shared_storage: not used, here for historical reasons. Deb822
objects never use shared storage anymore.
:param encoding: Interpret the paragraphs in this encoding.
(All values are given back as unicode objects, so an encoding is
necessary in order to properly interpret the strings.)
:param strict: dict of settings to tune the internal parser if that is
being used. See the documentation for :class:`Deb822` for details.

:param fd: file-like object to which the data should be written
(see notes below)
:param encoding: str, optional (Defaults to object default).
Encoding to use when writing out the data.
:param text_mode: bool, optional (Defaults to ``False``).
Encoding should be undertaken by this function rather than by the
caller.
If fd is None, returns a unicode object. Otherwise, fd is assumed to
be a file-like object, and this method will write the data to it
instead of returning a unicode object.
If fd is not none and text_mode is False, the data will be encoded
to a byte string before writing to the file. The encoding used is
chosen via the encoding parameter; None means to use the encoding the
object was initialized with (utf-8 by default). This will raise
UnicodeEncodeError if the encoding can't support all the characters in
the Deb822Dict values.

R# )�_PkgRelationMixiniF aK Package relationship mixin
Inheriting from this mixin you can extend a :class:`Deb822` object with
attributes letting you access inter-package relationship in a structured
way, rather than as strings.
For example, while you can usually use ``pkg['depends']`` to
obtain the Depends string of package pkg, mixing in with this class you
gain pkg.depends to access Depends as a Pkgrel instance
To use, subclass _PkgRelationMixin from a class with a _relationship_fields
attribute. It should be a list of field names for which structured access
is desired; for each of them a method wild be added to the inherited class.
The method name will be the lowercase version of field name; '-' will be
mangled as '_'. The method would return relationships in the same format of
the PkgRelation' relations property.
See Packages and Sources as examples.

and other packages.
Dictionary keys depend on the package kind. Binary packages have keys
like 'depends', 'recommends', ... while source packages have keys like
'build-depends', 'build-depends-indep' and so on. See the Debian policy
for the comprehensive field list.
Dictionary values are package relationships returned as lists of lists
of dictionaries (see below for some examples).
The encoding of package relationships is as follows:
- the top-level lists corresponds to the comma-separated list of
:class:`Deb822`, their components form a conjunction, i.e. they
have to be AND-ed together
- the inner lists corresponds to the pipe-separated list of
:class:`Deb822`,
their components form a disjunction, i.e. they have to be OR-ed
together
- member of the inner lists are dictionaries with the following keys:
``name``
package (or virtual package) name
``version``
A pair <`operator`, `version`> if the relationship is
versioned, None otherwise. operator is one of ``<<``,
``<=``, ``=``, ``>=``, ``>>``; version is the given version as
a string.
``arch``
A list of pairs <`enabled`, `arch`> if the
relationship is architecture specific, None otherwise.
Enabled is a boolean (``False`` if the architecture is
negated with ``!``, ``True`` otherwise), arch the
Debian architecture name as a string.
``restrictions``
A list of lists of tuples <`enabled`, `profile`>
if there is a restriction formula defined, ``None``
otherwise. Each list of tuples represents a restriction
list while each tuple represents an individual term
within the restriction list. Enabled is a boolean
(``False`` if the restriction is negated with ``!``,
``True`` otherwise). The profile is the name of the
build restriction.
https://wiki.debian.org/BuildProfileSpec
The arch and restrictions tuples are available as named tuples so
elements are available as `term[0]` or alternatively as
`term.enabled` (and so forth).
Examples:
``"emacs | emacsen, make, debianutils (>= 1.7)"``
becomes::
[
[ {'name': 'emacs'}, {'name': 'emacsen'} ],
[ {'name': 'make'} ],
[ {'name': 'debianutils', 'version': ('>=', '1.7')} ]
]
``"tcl8.4-dev, procps [!hurd-i386]"``
becomes::
[
[ {'name': 'tcl8.4-dev'} ],
[ {'name': 'procps', 'arch': (false, 'hurd-i386')} ]
]
``"texlive <!cross>"``
becomes::
[
[ {'name': 'texlive', 'restriction': [[(false, 'cross')]]} ]

This class is a thin wrapper around the transparent GPG handling
of :class:`_gpg_multivalued`, the field parsing of
:class:`_PkgRelationMixin`,
and the format parsing of :class:`Deb822`.
Note that the 'relations' structure returned by the `relations` method
is identical to that produced by other classes in this module.
Consequently, existing code to consume this structure can be used here,
although it means that there are redundant lists and tuples within the
structure.
