问题描述
我们正在将一个大型svn存储库(超过10万转)拆分为几个较小的存储库.我正在使用svndumpfilter(v1.7.2)拆分转储，并使用svndumptool/sed过滤大型转储.
We are splitting a big svn repository (100k+ revs) into several smaller repos.I am using svndumpfilter (v1.7.2) to split the dump and svndumptool/sed to filter the big dump.
一切正常，但即使我使用了"drop-empty-revs"选项，过滤后的转储中仍然存在一些填充修订".
Everything works fine, except that there are still some "padding revisions" in my filtered dump, even though I used the option "drop-empty-revs".
当我们有不到10％的无用的填充修订"时，这并不是什么大问题，但是有时，新的仓库只有几百个真正的修订，被掩埋在3万多个填充修订"中.
This is not too problematic when we have less than 10% of useless "padding revisions" but sometimes, the new repo has only a few hundreds real revisions that are buried in 30k+ "padding revisions".
这是我使用的命令及其包含的修订版本
Here is the command I use and the revisions that are included
svndumpfilter --drop-empty-revs --renumber-revs include /MyProj < MassiveOldRepo.dump > NewAllCleanRepo.dump

This is an empty revision for padding.

This is an empty revision for padding.

我想知道是否有一种方法在我过滤转储时不包括这些修订版(无需从已过滤的转储中手动删除它们).
我要补充一点，我对svndumpfilter的使用会删除一些空修订，即第一个真实"修订之前的修订和最后一个真实"修订之后的修订.
I would add that my use of svndumpfilter drops some empty revisions, the ones before the first "real" revision and the ones after the last "real" revision.
推荐答案
经过数小时的测试，阅读svndumpfilter源代码(注释非常好，做得很好！)，我意识到这些空的修订本不是来自我的过滤条件.
After hours of tests, reading the svndumpfilter source code (which is very well commented, well done!), I realize that these empty revisions don't come from my filtering.
它们已经放在我原始的转储文件中，以及日期自2005年起.
They are already lying in my original dump and date from 2005.
结论:首先检查您的数据！
Conclusion : Check your data first!!
