The user can now set the make variable BUILD_PYTHON to select which interpreter runs key2pub.py. key2pub.py is further simplified as well. Original Intro: crda's build system is one of the last packages with a hard dep on python-2.7 on my Gentoo system. This patchset adapts the utility script 'key2pub.py' so that it will run under either Python 2.7 or Python 3.x. The main change is a switch from using M2Crypto to PyCrypto, specifically for Python 3.x support. In addition, Gentoo had a small collection of bugfix patches that were applied every time someone installed crda. I've included those that seemed to have general applicability, as described in Patch 2. ^ permalink raw reply [flat|nested] 5+ messages in thread

This required some minor syntactical changes as well as switching from M2Crypto to pycrypto, since M2Crypto doesn't support python 3.x. The generate source files have been renamed to keys-*.h, to prevent a pattern rule from attempting to build the generated file. In addition, some errors in the generated source file keys-ssl.h are fixed: * The correct OpenSSL header for BN_ULONG is included. * The generated constants are given the 'ull' suffix to prevent warnings about constants that are too large. --- Makefile | 14 ++-- reglib.c | 4 +- utils/key2pub.py | 195 +++++++++++++++++++++++++++---------------------------- 3 files changed, 106 insertions(+), 107 deletions(-) mode change 100755 => 100644 utils/key2pub.py diff --git a/Makefile b/Makefile index a3ead30..4ce900c 100644 --- a/Makefile +++ b/Makefile @@ -25,6 +25,10 @@ UDEV_RULE_DIR?=/lib/udev/rules.d/ PUBKEY_DIR?=pubkeys RUNTIME_PUBKEY_DIR?=/etc/wireless-regdb/pubkeys +# Handle for the user to change the python interpreter that runs +# utils/key2pub.py.

It would be even better to use context manager (i.e. `with io.open(f, 'rb') as key_file:`) since it will close the file automatically. Other than this the patches look good, crda builds with both Python 2 and Python 3 with the patch and produce the same keys-gcrypt.h files. Comparing to the keys-gcrypt.c, apart from the trivial formatting changes, the ul suffixes for numbers are the only difference. I was not able to build crda with USE_OPENSSL=1 with or without this patch due to a large number of compilation errors. However, the differences between keys-ssl.c and keys-ssl.h are equivalent to the grypt ones. Also the addition of ul suffixes fixed the overflow errors, so definitely an improvement in this case as well. ^ permalink raw reply [flat|nested] 5+ messages in thread
