Git挂钩仅在提交时失败

Question

执行摘要

我有一个带有自定义预提交钩子的项目，其中一棵树看起来像这样：

parent
|
- .git - hooks - pre-commit
|
- smoketests - argument_tests.sh
|
- bitshuffle.py

当我运行.git / hooks / pre-commit时，它运行完美，每次测试都通过。但是，当我运行git commit时，某些测试会失败。我的索引与我的工作树完全相同。我不知道出了什么问题。

感谢您的帮助。

回溯

$ git commit
Running tests...

When run with no args, prints help... PASSED
When run with '-h', prints help... PASSED
When given bad compresstype, prints help... PASSED
When given bad editor, prints editor not found... FAILED

'Editor /nonexistent not found' does not match logfile

        Nothing to decode or nothing matched spec. Aborting.


When given bad input, prints file not found... PASSED

1 tests failed.

想出来。如果终端是交互式的，那么程序的反应是不同的。从脚本运行测试使终端成为非交互式。

罪魁祸首：

        if stdin.isatty() and args.input == '/dev/stdin':
        # ask the user to paste the packets into $VISUAL
            is_tmp = True
            if not args.editor:
                args.editor = find_editor()

            if not check_for_file(args.editor):
                print("Editor %s not found" % args.editor)
                sys.exit(4)

如果stdin.isatty()返回false，则此位将永远不会运行。
