Question

针对大型Subversion存储库（100k +提交）运行git svn clone或git svn fetch时，提取会定期停止：

Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.
error: The last gc run reported the following. Please correct the root cause and remove .git/gc.log.
Automatic cleanup will not be performed until the file is removed.

warning: There are too many unreachable loose objects; run 'git prune' to remove them.

gc --auto: command returned error: 255

为了恢复，我必须按照说明操作，运行更积极的修剪和gc，删除日志文件并继续，只是在读取另一批10k提交后再次发生。

如何避免这个问题？

Answer 1

我认为如果您将配置选项gc.pruneExpire设置为now，至少在导入过程中会暂时，它会避免该消息。使用该选项集，git gc将立即删除所有无法访问的对象，而不是仅删除至少两周（默认值）的对象。加上gc.auto的合理值，这可以防止它们累积到你得到该信息的程度。

Answer 2

自应答。

git svn操作是启动后台gc --auto内务操作的操作之一。在这种情况下，我认为git svn fetch的持续进展可能导致gc操作中某个点的不可到达/松散对象的数量超过auth-threshold，从而导致此警告。不幸的是，这对正在进行的获取来说是致命的。

我的解决方案是暂时禁用/怀疑这些gc操作，通过停用gc auto，如其手册页所述：

git config gc.auto 0

git svn fetch操作完成后，您可以根据需要删除此配置，并运行手动完整gc，剪枝和重新打包操作以优化最终存储库。

开始在git pull上看到此警告：

$ git pull
remote: Enumerating objects: 22, done.
remote: Counting objects: 100% (22/22), done.
remote: Compressing objects: 100% (5/5), done.
remote: Total 22 (delta 17), reused 22 (delta 17), pack-reused 0
Unpacking objects: 100% (22/22), done.
Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.

and remove .git/gc.log.
Automatic cleanup will not be performed until the file is removed.

warning: There are too many unreachable loose objects; run 'git prune' to remove them.

Already up-to-date.

检出警告文件，那里不多：

$ cat .git/gc.log
warning: There are too many unreachable loose objects; run 'git prune' to remove them.

阅读帮助：

$ git help gc

像我们这样的声音应该定期进行

运行偶尔推荐的主动选项

$ git gc --aggressive
Counting objects: 41544, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (40544/40544), done.
Writing objects: 100% (41544/41544), done.
Total 41544 (delta 30536), reused 7801 (delta 0)
Removing duplicate objects: 100% (256/256), done.
Checking connectivity: 46959, done.

删除日志警告：

$ rm .git/gc.log
