[issue38550] hashlib missing algorithms
New submission from Mike Gilbert :
After upgrading to Python 3.7.5, several algorithms are unavailable in the
hashlib module.
This seems to have been caused by the "fix" for
https://bugs.python.org/issue33936. I will submit a PR with a more appropriate
change shortly.
Python 3.7.4:
>>> hashlib.algorithms_available
{'ripemd160', 'blake2s256', 'sha512', 'sha3-224', 'sha3_224', 'blake2s',
'shake_128', 'sha3-384', 'sha3_384', 'whirlpool', 'md4', 'md5', 'sha512-224',
'sha3-512', 'sha1', 'blake2b', 'sha384', 'md5-sha1', 'sha3-256', 'shake_256',
'mdc2', 'sha224', 'blake2b512', 'shake128', 'sm3', 'sha256', 'shake256',
'sha3_512', 'sha512-256', 'sha3_256'}
Python 3.7.5:
>>> hashlib.algorithms_available
{'sha224', 'sha256', 'sha3_224', 'blake2s', 'md5', 'sha3_256', 'sha384',
'sha3_512', 'sha3_384', 'shake_256', 'blake2b', 'sha512', 'shake_128', 'sha1'}

Mike Gilbert added the comment: I see that generate_hash_name_list() calls EVP_MD_do_all() which calls OPENSSL_init_crypto(OPENSSL_INIT_ADD_ALL_DIGESTS, NULL); I'm not sure why that doesn't do the job here. -- ___ Python tracker <https://bugs.python.org/issue38550> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue38550] hashlib missing algorithms
Mike Gilbert added the comment: Ok, so this appears to be working correctly on master. Just the 3.7 branch is broken. I think this is because we use OBJ_NAME_do_all instead of EVP_MD_do_all in 3.7. I think backporting https://github.com/python/cpython/pull/16083 to 3.7 would resolve this. -- ___ Python tracker <https://bugs.python.org/issue38550> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue45433] libpython should not be linked with libcrypt
New submission from Mike Gilbert :
In https://bugs.python.org/issue44751, crypt.h was removed from Python.h. This
would imply that libpython is not meant to expose any crypt-related symbols.
In fact, it looks like libpython does not use crypt() or crypt_r() at all.
These are only used by cryptmodule.
In configure.ac, we have this this logic to determine if crypt_r() is available:
```
# We search for both crypt and crypt_r as one or the other may be defined
# This gets us our -lcrypt in LIBS when required on the target platform.
AC_SEARCH_LIBS(crypt, crypt)
AC_SEARCH_LIBS(crypt_r, crypt)
AC_CHECK_FUNC(crypt_r,
AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[
#define _GNU_SOURCE /* Required for crypt_r()'s prototype in glibc. */
#include
]], [[
struct crypt_data d;
char *r = crypt_r("", "", &d);
]])],
[AC_DEFINE(HAVE_CRYPT_R, 1, [Define if you have the crypt_r() function.])],
[])
)
```
The AC_SEARCH_LIBS macro adds "-lcrypt" to LIBS, and this gets passed down to
the link command for libpython. This is probably not intentional.
The HAVE_CRYPT_R value is used in _cryptmodule.c. setup.py performs its own
check for libcrypt when building the module.
I think the value of LIBS should be saved before the AC_SEARCH_LIBS calls and
restored after the AC_CHECK_FUNC call. I have tested this locally on Gentoo
Linux, and it seems to work fine.
I will work on a pull request.

[issue30008] OpenSSL 1.1.0 deprecated functions
New submission from Mike Gilbert: Some effort was made to port Python to OpenSSL 1.1.0 (see issue 26470). However, the code still uses several deprecated functions, and fails to compile against OpenSSL 1.1.0 if these functions are disabled. This may be replicated by building OpenSSL with --api=1.1.0. This will disable all functions marked as deprecated. I have attached a build log from the cpython master branch.

[issue31769] configure includes user CFLAGS testing detecting pthreads support
New submission from Mike Gilbert : When testing for ptheads support in the compiler, configure includes the CFLAGS value from the environment. If CFLAGS contains -pthread, or an option which implies -pthread (like -fopenmp), this will cause configure to not include -pthread in the CC variable, and -pthread will not be passed to the linker.

Downstream bug report: https://bugs.gentoo.org/631488 glibc-2.26 release notes: https://sourceware.org/ml/libc-alpha/2017-08/msg00010.html The nis module is normally skipped since rpcsvc/yp_prot.h will not exist.

To summarize: glibc no longer provides rpc/rpc.h or rpcsvc/yp_prot.h. One must install a couple of external libraries to provide the same functionality. The missing rpcsvc/yp_prot.h file can be resolved by installing the "libnsl" package, which installs the header where setup.py expects to find it. The missing rpc/rpc.h file may be provided by the "libtirpc" package, but this installs the file under /usr/include/tirpc, which must be added to the include path (-I/usr/include/tirpc). Ideally, pkg-config would be used to find both libnsl and libtirpc. -- components: Build messages: 306090 nosy: floppymaster priority: normal severity: normal status: open title: nis module fails to build against glibc-2.26 type: compile error ___ Python tracker <https://bugs.python.org/issue32007> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
