17 | It assigned libraries for multiprocessing module according | ||
18 | the host_platform, but not pass it to Extension. | ||
19 | |||
20 | In glibc, the following commit caused two definition of | ||
21 | sem_getvalue are different. | ||
22 | https://sourceware.org/git/?p=glibc.git;a=commit;h=042e1521c794a945edc43b5bfa7e69ad70420524 | ||
23 | (see diff in nptl/sem_getvalue.c for detail) | ||
24 | `__new_sem_getvalue' is the latest sem_getvalue@@GLIBC_2.1 | ||
25 | and `__old_sem_getvalue' is to compat the old version | ||
26 | sem_getvalue@GLIBC_2.0. | ||
27 | |||
28 | To build python for embedded Linux systems: | ||
29 | http://www.yoctoproject.org/docs/2.3.1/yocto-project-qs/yocto-project-qs.html | ||
30 | If not explicitly link to library pthread (-lpthread), it will | ||
31 | load glibc's sem_getvalue randomly at runtime. | ||
32 | |||
33 | Such as build python on linux x86_64 host and run the python | ||
34 | on linux x86_32 target. If not link library pthread, it caused | ||
35 | multiprocessing bounded semaphore could not work correctly. | ||
36 | ... | ||
37 | >>> import multiprocessing | ||
38 | >>> pool_sema = multiprocessing.BoundedSemaphore(value=1) | ||
39 | >>> pool_sema.acquire() | ||
40 | True | ||
41 | >>> pool_sema.release() | ||
42 | Traceback (most recent call last): | ||
43 | File "<stdin>", line 1, in <module> | ||
44 | ValueError: semaphore or lock released too many times | ||
45 | ... | ||
46 | |||
47 | And the semaphore issue also caused multiprocessing.Queue().put() hung. | ||
