* Use 'with file' more.Zac Medico2012-12-281-9/+8
| | | | This helps to minimize ResourceWarning triggered by ^C with python3.
* Replace getstatusoutput with unicode safe Popen.Zac Medico2012-09-111-4/+13
| | | | This fixes potential issues similar to those reported in bug #310789.
* _apply_hash_filter: make hash_filter simplerZac Medico2012-08-211-2/+6
| | | | | Now any callable object will work, which might be helpful for consumers of the Manifest.checkFileHashes() method.
* Implement PORTAGE_CHECKSUM_FILTER for bug #432170Zac Medico2012-08-211-0/+54

* Skip whirlpool digest check when unaccelerated.Zac Medico2012-07-121-0/+20
| | | | | | | | If multiple digests are available and whirlpool is unaccelerated, then skip it. This allows extreme performance problems like bug #425046 to be avoided whenever practical, especially for cases like stage builds where acceleration may not be available for some hashes due to minimization of dependencies.
* perform_all: fix TypeError for bug #411897Zac Medico2012-04-131-1/+1

* checksum.py: remove PyPy 1.7 workaroundsZac Medico2012-02-131-30/+1
| | | | | | The corresponding hashlib issues are fixed in PyPy 1.8: https://bugs.pypy.org/issue957
* checksum.py: detect PyPy crashes in hashlibZac Medico2011-12-011-0/+29
| | | | | | | | Use a fork to try and PyPy by digesting random data with hashlib functions. It doesn't look like a bug has been reported upstream for this yet, so it may or may not be reproducible by others. Anyway, this allows me to avoid crashing the main PyPy process until I find a real fix.

* Manifest2 hash backend provider: mhashRobin H. Johnson2011-10-011-0/+19
| | | | | | | | | | Offer mhash as a provider for Manifest2 hash generation and validation. This is important as either of pycrypto or fchksum offer an accelerated Whirlpool implementation, and hashlib might not offer it. Additionally, the mhash implementation is accelerated and ships with a rigorious testsuite. Signed-off-by: Robin H. Johnson <robbat2@gentoo.org>
* Manifest2 hash: SHA512Robin H. Johnson2011-10-011-0/+1

* Refactor RMD160 hashlib code for less-hardcodingRobin H. Johnson2011-10-011-9/+12

* With python-2.6, importing the Crypto.Hash.MD5 and Crypto.Hash.SHA modulesZac Medico2008-11-081-4/+1
| | | | | | | | | | | | from pycrypto triggers warnings since those modules are implemented using the deprecated md5 and sha modules from python's stdlib. So, in order to avoid the warning and the inferior hash implementations that come with them, never use these particular modules from pycrypto. Instead, use hashlib or directly use stdlib's md5 and sha modules if necessary. Thanks to Markus Peloquin for reporting. svn path=/main/trunk/; revision=11828
