We aim to +replace all use of dnf.yum.misc.checksum() with this. In doing so, this +fixes installing previously downloaded and transcoded rpms to support + +https://github.com/rpm-software-management/librepo/pull/222 + +This also has some minor performance benefits: librepo's checksum +handling employs caching of previously downloaded files via extended +attributes. This works for ordinary rpms in the dnf cache, but does not +work (yet) for rpm paths specified on the command line due to +https://github.com/rpm-software-management/librepo/issues/233. That +issue is pretty minor, and the fix ends up in libdnf later. + +The previous implementation maps all runtime errors to MiscError. We do +this still by taking the libdnf.error.Error class (defined in SWIG) and +map it directly back to the Python exception as before. +--- + dnf/package.py | 18 ++++---- + dnf/yum/misc.py | 113 ------------------------------------------------ + 2 files changed, 10 insertions(+), 121 deletions(-) + +diff --git a/dnf/package.py b/dnf/package.py +index b01e555eba..fc89cf98a8 100644 +--- a/dnf/package.py ++++ b/dnf/package.py +@@ -30,6 +30,8 @@ + import dnf.rpm + import dnf.yum.misc + import hawkey ++import libdnf.error ++import libdnf.utils + import logging + import os + import rpm +@@ -56,7 +58,10 @@ def _chksum(self): + return self._priv_chksum + if self._from_cmdline: + chksum_type = dnf.yum.misc.get_default_chksum_type() +- chksum_val = dnf.yum.misc.checksum(chksum_type, self.location) ++ try: ++ chksum_val = libdnf.utils.checksum_value(chksum_type, self.location) ++ except libdnf.error.Error as e: ++ raise dnf.exceptions.MiscError(str(e)) + return (hawkey.chksum_type(chksum_type), + binascii.unhexlify(chksum_val)) + return super(Package, self).chksum +@@ -330,10 +335,7 @@ def verifyLocalPkg(self): + if self._from_cmdline: + return True # local package always verifies against itself + (chksum_type, chksum) = self.returnIdSum() +- real_sum = dnf.yum.misc.checksum(chksum_type, self.localPkg(), +- datasize=self._size) +- if real_sum != chksum: +- logger.debug(_('%s: %s check failed: %s vs %s'), +- self, chksum_type, real_sum, chksum) +- return False +- return True ++ try: ++ return libdnf.utils.checksum_check(chksum_type, self.localPkg(), chksum) ++ except libdnf.error.Error as e: ++ raise dnf.exceptions.MiscError(str(e)) +diff --git a/dnf/yum/misc.py b/dnf/yum/misc.py +index 3e3905feb8..af018a8a1b 100644 +--- a/dnf/yum/misc.py ++++ b/dnf/yum/misc.py +@@ -22,7 +22,6 @@ + + from __future__ import print_function, absolute_import + from __future__ import unicode_literals +-from dnf.exceptions import MiscError + from dnf.pycomp import base64_decodebytes, basestring, unicode + from stat import * + import libdnf.utils +@@ -32,7 +31,6 @@ + import dnf.i18n + import errno + import glob +-import hashlib + import io + import os + import os.path +@@ -41,7 +39,6 @@ + import shutil + import tempfile + +-_available_checksums = set(['md5', 'sha1', 'sha256', 'sha384', 'sha512']) + _default_checksums = ['sha256'] + + +@@ -68,119 +65,9 @@ def re_full_search_needed(s): + return True + return False + +- +-class Checksums(object): +- """ Generate checksum(s), on given pieces of data.
