Darwin

除了使用pytest.fixture.userfixtures和传参两种显式的调用fixture之外.也可以自动的执行fixture,在定义fixture的时候设置autouser=True即可 from datetime import datetime from time import sleep import pytest @pytest.fixture(autouse=True) def timer_session_scope(): start = datetime.now() print(f"\nstart:{start}") yield end = datetime.now() print(f"total time cost:{end - start}") def test_timer(): sleep(1.3) assert 2 == 2 运行结果: ╰ pytest -v -s test_data.py ======================================================= test session starts ======================================================== platform darwin -- Python 3.7.4, pytest-4.4.0, py-1

I am able to update gcc on Linux to get -std=c++17 but cannot do the same on Mac. Is there a version of Clang I can update to or some other alternative to get C++17 on my Mac? Please help. Thanks. On my 10.11 El Capitan, Xcode 7.3.1, clang has been updated to: Apple LLVM version 7.3.0 (clang-703.0.31) which is almost equivalent to llvm version 3.8. clang++ hasn't -std=c++17 option, but -std=c++1z , working well at present, though only supporting some features of C++1z. For gcc, you can install a very new one by: brew install gcc --HEAD which will install gcc-6.1 now, (2016.8). This gcc has

I'm having problems getting my rsync syntax right and I'm wondering if my scenario can actually be handled with rsync. First, I've confirmed that rsync is working just fine between my local host and my remote host. Doing a straight sync on a directory is successful. Here's what my filesystem looks like: uploads/ 1260000000/ file_11_00.jpg file_11_01.jpg file_12_00.jpg 1270000000/ file_11_00.jpg file_11_01.jpg file_12_00.jpg 1280000000/ file_11_00.jpg file_11_01.jpg file_12_00.jpg What I want to do is run rsync only on files that begin with "file_11_" in the subdirectories and I want to be able

I would like to rename symbols inside object files (.o) with something that would be the Mac equivalent of binutils' objcopy --redefine-syms tool. I found no arm-apple-darwin10-objcopy . I tried the MacPorts' arm-elf-binutils port and also tried to play a bit with otool and segedit without much success. Any ideas please? synthesizerpatel Sounds like a job for Agner Fog's objconv . From the announcement : I have now finished making full support for Mach-O files in the object file converter mentioned in my previous posts. You may use it as a replacement for the missing objcopy utility. Objconv

On Darwin, the POSIX standard clock_gettime(CLOCK_MONOTONIC) timer is not available. Instead, the highest resolution monotonic timer is obtained through the mach_absolute_time function from mach/mach_time.h . The result returned may be an unadjusted tick count from the processor, in which case the time units could be a strange multiple. For example, on a CPU with a 33MHz tick count, Darwin returns 1000000000/33333335 as the exact units of the returned result (ie, multiply the mach_absolute_time by that fraction to obtain a nanosecond value). We usually wish to convert from exact ticks to
