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/stretch/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/stretch/dpkg-dev/deb-changes.5.html>`_, `changes` files that developers upload to add new packages to the archive. - `dsc(5) <https://manpages.debian.org/stretch/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 * :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) or a string. 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) Deb822 Classes -------------- N)AnyCallablecastDict FrozenSet GeneratorIteratorIterableIOListMappingMutableMappingOptionaloverloadProtocolSetTextTupleTypeTypeVarUnion TYPE_CHECKING T_Deb822Dict Deb822Dictbound)Literal TypedDictFc C d S N fr r //usr/lib/python3/dist-packages/debian/deb822.py<lambda>) r$ c C s |S r r )tvr r r# r$ * r% ) OrderedSet_CaseInsensitiveString_strIdefault_field_sort_key)function_deprecated_byTc C s* z| W dS ttjfy Y dS w )zp test that a file-like object is really a filehandle Only filehandles can be given to apt_pkg.TagFile.

Z ZS )$r a3 A dictionary-like object suitable for storing RFC822-like data. 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.

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.

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.

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).

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.

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')]]} ] ] c s j | d u S r )r )r. rN r r# r$ s z-_PkgRelationMixin.relations.<locals>.<lambda>T)r filterr rF rK rr )rA lazy_relsr. r rN r# relations s O z_PkgRelationMixin.relationsN)r5 r6 r7 r8 r r@ propertyr r r r r# r V s r c s4 e Zd ZdZi Zdd Z fddZdd Z ZS ) _multivaluedaU A class with (R/W) support for multivalued fields. To use, create a subclass with a _multivalued_fields attribute. It should be a dictionary with *lower-case* keys, with lists of human-readable identifiers of the fields as the values.

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.

Implement the method:: @classmethod def _class_init(cls, new_attrs): pass on a class, and apply this metaclass to it. The _class_init method will be called right after the class is created. The 'new_attrs' param is a dict containing the attributes added in the definition of the class. c s" t t| ||| | | d S r )r? r+ r@ _class_init)r rS basesattrsrC r r# r@ s z_ClassInitMeta.__init__)r5 r6 r7 r8 r@ r] r r rC r# r+ q s r+ c s( e Zd ZdZ d fdd Z ZS )RestrictedFieldzPlaceholder for a property providing access to a restricted field.

The getter that will replace this returns (or applies the given to_str function to) None for fields that do not exist in the underlying data object. :param name: The name of the deb822 field. :param from_str: The function to apply for getters (default is to return the string directly). :param to_str: The function to apply for setters (default is to use the value directly). If allow_none is True, this function may return None, in which case the underlying key is deleted. :param allow_none: Whether it is allowed to set the value to None (which results in the underlying key being deleted). )from_strto_str allow_none)r? r/ __new__)r rS r0 r1 r2 rC r r# r3 s zRestrictedField.__new__)NNT)r5 r6 r7 r8 r3 r] r r rC r# r/ s r/ z name from_str to_str allow_nonec sv e Zd ZdZe Zedd Zedd Z fddZ dd Z d d Z d d Z dd Z dd Z dddZ ZS )RestrictedWrappera@ Base class to wrap a Deb822 object, restricting write access to some keys. The underlying data is hidden internally. Subclasses may keep a reference to the data before giving it to this class's constructor, if necessary, but RestrictedField should cover most use-cases. The dump method from Deb822 is directly proxied.
