Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.

class portage.dbapi.bintree.binarytree(_unused=<class 'DeprecationWarning'>, pkgdir=None, virtual=<class 'DeprecationWarning'>, settings=None)

Bases: object

this tree scans for a list of all packages available in PKGDIR

_allocate_filename(cpv)
_allocate_filename_multi(cpv)
_ensure_dir(path)

Create the specified directory. Also, copy gid and group mode bits from self.pkgdir if possible. :param cat_dir: Absolute path of the directory to be created. :type cat_dir: String

_eval_use_flags(cpv, metadata)
_file_permissions(path)
_get_digests(pkg)
_inject_file(pkgindex, cpv, filename)

Add a package to internal data structures, and add an entry to the given pkgindex. :param pkgindex: The PackageIndex instance to which an entry

will be added.

Parameters

  • cpv (_pkg_str) – A _pkg_str instance corresponding to the package being injected.

  • filename (string) – Absolute file path of the package to inject.

Return type

dict

Returns

A dict corresponding to the new entry which has been added to pkgindex. This may be used to access the checksums which have just been generated.

_is_specific_instance(cpv)
_load_pkgindex()
_max_build_id(cpv)
static _merge_pkgindex_header(src, dest)

Merge Packages header settings from src to dest, in order to propagate implicit IUSE and USE_EXPAND settings for use with binary and installed packages. Values are appended, so the result is a union of elements from src and dest.

Pull in ARCH if it’s not defined, since it’s used for validation by emerge’s profile_check function, and also for KEYWORDS logic in the _getmaskingstatus function.

Parameters
_new_pkgindex()
static _parse_build_id(filename)
_pkgindex_entry(cpv)

Performs checksums, and gets size and mtime via lstat. Raises InvalidDependString if necessary. :rtype: dict :return: a dict containing entry for the give cpv.

_pkgindex_version_supported(pkgindex)
_pkgindex_write(pkgindex)
_populate_additional(repos)
_populate_local(reindex=True)

Populates the binarytree with local package metadata.

Parameters

reindex (bool) – detect added / modified / removed packages and regenerate the index file if necessary

_populate_remote(getbinpkg_refresh=True)
_propagate_config(config)

Propagate implicit IUSE and USE_EXPAND settings from the binary package database to a config instance. If settings are not available to propagate, then this will do nothing and return False.

Parameters

config (portage.config) – config instance

Return type

bool

Returns

True if settings successfully propagated, False if settings were not available to propagate.

_read_metadata(filename, st, keys=None, binpkg_format=None)

Read metadata from a binary package. The returned metadata dictionary will contain empty strings for any values that are undefined (this is important because the _pkg_str class distinguishes between missing and undefined values).

Parameters

  • filename (string) – File path of the binary package

  • st (os.stat_result) – stat result for the binary package

  • keys (iterable) – optional list of specific metadata keys to retrieve

Return type

dict

Returns

package metadata

_update_pkgindex_header(header)

Add useful settings to the Packages file header, for use by binhost clients.

This will return silently if the current profile is invalid or does not have an IUSE_IMPLICIT variable, since it’s useful to maintain a cache of implicit IUSE settings for use with binary packages.

dep_bestmatch(mydep)

compatibility method – all matches, not just visible ones

digestCheck(pkg)

Verify digests for the given package and raise DigestException if verification fails. :rtype: bool :return: True if digests could be located, False otherwise.

exists_specific(cpv)
get_pkgindex_uri(cpv)

Returns the URI to the Packages file for a given package.

getname(cpv, allocate_new=None)

Returns a file location for this package. If cpv has both build_time and build_id attributes, then the path to the specific corresponding instance is returned. Otherwise, allocate a new path and return that. When allocating a new path, behavior depends on the binpkg-multi-instance FEATURES setting.

getslot(mycatpkg)

Get a slot for a catpkg; assume it exists.

gettbz2(pkgname)

Fetches the package from a remote site, if necessary. Attempts to resume if the file appears to be partially downloaded.

inject(cpv, filename=None)

Add a freshly built package to the database. This updates $PKGDIR/Packages with the new package metadata (including MD5). :param cpv: The cpv of the new package to inject :type cpv: string :param filename: File path of the package to inject, or None if it’s

already in the location returned by getname()

Return type

_pkg_str or None

Returns

A _pkg_str instance on success, or None on failure.

isremote(pkgname)

Returns true if the package is kept remotely and it has not been downloaded (or it is only partially downloaded).

move_ent(mylist, repo_match=None)
populate(getbinpkgs=False, getbinpkg_refresh=True, add_repos=())

Populates the binarytree with package metadata.

Parameters

  • getbinpkgs (bool) – include remote packages

  • getbinpkg_refresh (bool) – attempt to refresh the cache of remote package metadata if getbinpkgs is also True

  • add_repos (sequence) – additional binary package repositories

class portage.dbapi.bintree.bindbapi(mybintree=None, **kwargs)

Bases: portage.dbapi.virtual.fakedbapi

_categories = None
_category_re = re.compile('^\\w[-.+\\w]*$')
_clear_cache()
static _cmp_cpv(cpv1, cpv2)
static _cpv_sort_ascending(cpv_list)

Use this to sort self.cp_list() results in ascending order. It sorts in place and returns None.

_instance_key_cpv(cpv, support_string=False)
_instance_key_multi_instance(cpv, support_string=False)
_iter_match(atom, cpv_iter)
_iter_match_repo(atom, cpv_iter)
_iter_match_slot(atom, cpv_iter)
_iter_match_use(atom, cpv_iter)

  1. Check for required IUSE intersection (need implicit IUSE here).

  2. Check enabled/disabled flag states.

_iuse_implicit_cnstr(pkg, metadata)

Construct a callable that checks if a given USE flag should be considered to be a member of the implicit IUSE for the given package.

Parameters
Returns

a callable that accepts a single USE flag argument, and returns True only if the USE flag should be considered to be a member of the implicit IUSE for the given package.

Return type

callable

_known_keys = frozenset({'BDEPEND', 'CHOST', 'DEFINED_PHASES', 'DEPEND', 'DESCRIPTION', 'EAPI', 'HOMEPAGE', 'IDEPEND', 'INHERIT', 'INHERITED', 'IUSE', 'KEYWORDS', 'LICENSE', 'PDEPEND', 'PROPERTIES', 'RDEPEND', 'REQUIRED_USE', 'RESTRICT', 'SLOT', 'SRC_URI', 'USE', 'repository'})
_match_use(atom, pkg, metadata, ignore_profile=False)
_pkg_str(cpv, repo)

This is used to contruct _pkg_str instances on-demand during matching. If cpv is a _pkg_str instance with slot attribute, then simply return it. Otherwise, fetch metadata and construct a _pkg_str instance. This may raise KeyError or InvalidData.

_pkg_str_aux_keys = ('EAPI', 'KEYWORDS', 'SLOT', 'repository', 'BINPKG_FORMAT', 'BUILD_ID', 'BUILD_TIME', '_mtime_')
_set_multi_instance(multi_instance)

Enable or disable multi_instance mode. This should before any packages are injected, so that all packages are indexed with the same implementation of self._instance_key.

_use_mutable = False
aux_get(mycpv, wants, myrepo=None)

Return the metadata keys in mylist for mycpv Args:

mycpv - “sys-apps/foo-1.0” mylist - [“SLOT”,”DEPEND”,”HOMEPAGE”] myrepo - The repository name.

Returns:

a list of results, in order of keys in mylist, such as: [“0”,”>=sys-libs/bar-1.0”,”http://www.foo.com”] or [] if mycpv not found’

aux_update(cpv, values)
Args:
cpv - “sys-apps/foo-1.0”

metadata_updates = { key : newvalue }

Use self.cp_all() to generate a category list. Mutable instances can delete the self._categories attribute in cases when the cached categories become invalid and need to be regenerated.

clear()

Remove all packages.

close_caches()
cp_all(sort=False)

Implement this in a child class Args

sort - return sorted results

Returns:

A list of strings 1 per CP in the datastore

cp_list(*pargs, **kwargs)
cpv_all()
