Git筛选器--在将文件添加到根提交时失败

Question

试图将文件添加到分支根目录的尝试失败，出现以下错误：

git filter-repo --force --commit-callback "if not commit.parents: commit.file_changes.append(FileChange(b'M', 'C:\MDC\MDC.7z', $(git hash-object -w 'C:\MDC\MDC.7z'), 100644))"

Answer 1

从Python的角度来看，3d5fb68077a1d627a7ec3b18f335713c4262fbf0必须是一个字符串('3d5fb68077a1d627a7ec3b18f335713c4262fbf0')，所以在它周围加上引号：

--commit-callback "if not commit.parents: commit.file_changes.append(FileChange(b'M', 'C:\MDC\MDC.7z', '$(git hash-object -w 'C:\MDC\MDC.7z')', 100644))"

Answer 2

git filter-repo --force --commit-callback "if not commit.parents: commit.file_changes.append(FileChange(b'M', b'MDC.7z', bytes('$(git hash-object -w 'C:\MDC\MDC.7z')',encoding='utf-8'), b'100644'))"

so:

• 100644
• FileChange的第2 param应该像run git rev-list --objects --all的路径。
• 每个param的FileChange都必须输入字节，b'100644'
• $(git hash-object -w 'C:\MDC\MDC.7z') -> -> bytes('$(git hash-object -w 'C:\MDC\MDC.7z')',encoding='utf-8')

。

示例：

$ git filter-repo --force --commit-callback "if not commit.parents: commit.file_changes.append(FileChange(b'M', b'1.txt', bytes('$(git hash-object -w 'D:\tmp\git\git1\1.txt')',encoding='utf-8'), b'100644'))"
