The following patches are currently in our packaging system. A brief summary: - Use 'cc -shared' to build shared libraries, as is strictly correct on OpenBSD. - Use -fPIC instead of -fpic. - Use OpenBSD threads. - Fix the test_fcntl test. Another patch item will be posted shortly for Python 2.2, for similar items. |

Logged In: YES user_id=21627 The -shared chunk looks frightening. What is the first BSD release where ld -Bshareable stops working? Could you rearrange this to integrate the version numbers into the OpenBSD* match? Also, what releases need the ELF test? Could that be restricted to the older releases, too? Would it be acceptable to stop supporting OpenBSD 0 and 1? Is usage of -fPIC correct on OpenBSD 0.x? If not, what is the first release that supports -fPIC? It looks like that 'OpenBSD threads' are 'POSIX threads'? Why does the existing test for Posix threads fail to detect their presence? |

Logged In: YES user_id=240525 Okay, well let's comment in this bug then. Changing the subject and closing out 554719. I'll put all patches on this bug. I am trying to verify most of this with brad@openbsd.org, who has contributed some parts of these patches. On cc -shared, this is my understanding: - All OpenBSD ELF architectures have always used cc -shared. - Before OpenBSD 2.8, a.out architectures used ld -Bshareable. - As of OpenBSD 2.8, cc -shared worked on a.out architectures as well, and ld -Bshareable became deprecated. On -fPIC: -fPIC has always worked. The difference between -fpic and -fPIC is simply that -fpic is less efficient. On threads, I am still waiting for an answer from brad@, this is his change. I'll ask him again today. Thanks. |

Logged In: YES user_id=240525 From brad@: > There isn't a test for -pthread option so Python will not correctly > compile with threads support. Testing for libc_r is NOT correct. So, the answer is no, the standard POSIX threads test does not work. |

Logged In: YES user_id=21627 What architectures have been using ELF before OpenBSD 2.8? I'd still like to simplify this logic, perhaps by removing support for systems that nobody uses anymore. As for -pthread: the test for OpenBSD specifically should go. Instead, I propose to integrate this with the -Kpthread logic: there should be a sequence of options tested, and the first one shown to enable pthreads should be used. The set of options should be -Kpthread (for SysV), -pthread (for BSD and Linux), -pthreads (for gcc on Solaris). I'd be willing to accept a test-for-system for 2.1, since it does not have the -Kpthread test, but for 2.2 and 2.3, we should remove the set of tests used. Also, why does it AC_DEFINE _REENTRANT and _POSIX_THREADS? Those two should be implied by -pthread. Also, what OpenBSD releases could be deprecated without losing users? |

Logged In: YES user_id=21627 Are you still interested in this patch? If so, what are the answers to these questions? |

Logged In: YES user_id=240525 I am no longer involved in OpenBSD. Chris Humphries took over the Python ports, he is reachable at <chumphries@drauku.net>. I let him know about these patches in early July. |

Logged In: YES user_id=21627 Ok, closing this patch. If Chris Humphries shows any interest, we can reopen it, or he can submit a new patch. |
