Description Othman Madjoudj 2015-03-27 22:47:22 UTC
Spec URL: https://athmane.fedorapeople.org/pkgs/fabric-el6/python-crypto2.1.spec
SRPM URL: https://athmane.fedorapeople.org/pkgs/fabric-el6/python-crypto2.1-2.1.0-1.el6.src.rpm


Python-crypto is a collection of both secure hash functions (such as MD5 and
SHA), and various encryption algorithms (AES, DES, RSA, ElGamal etc.).

This is a parallel update for EPEL6

Package Review

[x] = Pass, [!] = Fail, [-] = Not applicable, [?] = Not evaluated
[ ] = Manual review needed

- Package contains BR: python2-devel or python3-devel

The current build rquirement is set as:

BuildRequires:	python-devel >= 2.2, gmp-devel >= 4.1

But should be:

BuildRequires:	python2-devel, gmp-devel >= 4.1

Or even better IMHO:

BuildRequires:	python2-devel
BuildRequires:	gmp-devel >= 4.1

This is necessary because this package targets EPEL6 where
python2-devel is not part of the standard buildroot.

- Package provides "pycrypto".

I'm not 100% sure on this, but IMHO it looks like this, exposed as Python module at the "Crypto21" namespace can not be considered a provider of "pycrypto".

- python-crypto2.1-use-Crypto21.patch

This patch should only rename module names from 'Crypto.*' to
'Crypto21.*' and not all occurences of 'Crypto'.  That is, it probably
be a 's/Crypto\./Crypto21/g' instead of a 's/Crypto/Crypto21/g'
because of false positives such as:

-# into PyCrypto (the "Modifications").
+# into PyCrypto21 (the "Modifications").


-    This supports the API for Cryptographic Hash Functions (PEP 247).
+    This supports the API for Crypto21graphic Hash Functions (PEP 247).

and also:

-class CryptoWarning(Warning):
-    """Base class for PyCrypto warnings"""
+class Crypto21Warning(Warning):
+    """Base class for PyCrypto21 warnings"""

This will make code that depende on python-crypto fail because symbol
names are different.

- I'm attaching a modified version of the SPEC with a few
  changes/suggestions and also the added patch.

[x]: Package contains no static executables.
[x]: Development (unversioned) .so files in -devel subpackage, if present.
     Note: Unversioned so-files in private %_libdir subdirectory (see
