This solution was the only one that worked for me:
See what was the revision number of the last change on the file:
git svn log chrome/test/functional/search_engines.pyReset svn to be closest parent before that revision:
git svn reset -r62248 -pDo a
git svn fetch!Dance at your success.
When I update suuuuuper old Chromium repositories, I occasionally get that stupid Checksum mismatch from svn. It happens often enough that it's a thing, but uncommonly enough that I forget how to fix it each time. So, FOR PROSPERITY:
Checksum mismatch: trunk/src/chrome/test/functional/search_engines.py 5d1082dfc3e6363ece792d7cd49fde0a7ce9c6df
expected: e88e3ea6349cb44955d58e6a3964824f
got: af58cced63097504e4bfb6574c252f4a
Then proooobably what happens was search_engines.py downloaded wonky or something such that the hash no longer came to be the correct thing. So solution:
See what was the revision number of the last change on the file:git svn log chrome/test/functional/search_engines.py
Reset svn to be closest parent before that revision:git svn reset -r62248 -p
Do a git svn fetch!
Dance at your success.
总结：
出现这个情况，原因是，在同步svn服务器代码的时候出错了，仔细查看结果，发现同步到的对应文件的最后一次提交，更新失败了。
但是，那一次提交仍然被记录下来。
$ git svn rebase
Checksum mismatch: ZITaker/UI/TableForm.cs
expected: 1d341c96dacd486b6f071461b791f209
got: 605022e72af5d950f6cd32ad5fd157aa
找到TableForm.cs文件的最后一次日志的svn版本号，目前找到是1701
使用git svn reset -r1701 -p
