如何修复我的TortoiseSVN存储库中的损坏？

上个月，我们正常使用TortoiseSVN，但在尝试提交/更新一两个不常访问或更新的特定文件夹时，我们开始收到错误。“尝试在文件开始之前设置文件指针”和“sqllite[S8]：尝试写入只读数据库”错误混合出现。清理工作并没有解决这些问题

我们相信这个问题是由某个时候的磁盘故障引起的，但是由于这些问题只发生在这几个文件夹中，我们没有足够的备份来真正解决它。从那时起，我们又有近1000次提交。经过一些研究，我认为最好的方法是将所有有效的修订转储到一个新的存储库中，并在事后将错误的修订放回文件中

我遵循了此链接的建议：

下面是我使用的命令行svnadmin命令。D:\SVN是我们存储库的位置

检查错误修订：

svnadmin verify D:\SVN --keep-going

r33809: E140001: zlib <uncompress>: corupt data: Decompression of snvdiff data failed
r34866: E720131: Can't set position pointer in file D:\SVN\db\revs\34\34866': An attempt was made to move the file pointer before the beginning of the file.
r34892: E160004: Reading one svndiff window read beyond the end of the representation.
svnadmin: E205012: Failed to verify repository 'D:\SVN'

svnadmin dump D:\SVN -r 1:33800 > tortoisedump.txt
svnadmin dump D:\SVN -r 33801:33808 --incremental > tortoisedump33801-33808.txt

(Skipping 33809 and 33810)
svnadmin dump D:\SVN -r 33811:34808 --incremental > tortoisedump33811-34808.txt
svnadmin dump D:\SVN -r 34811:34865 --incremental > tortoisedump34811-34865.txt

(Skipping 34866 and 34867)
svnadmin dump D:\SVN -r 34868:34891 --incremental > tortoisedump34868-34891.txt

(Skipping 34892 and 34893)
svnadmin dump D:\SVN -r 34894:34997 --incremental > tortoisedump34894-34997.txt

(34998 showed as corrupt at one point, but not in my latest verify check. Excluded 34998 and 34999 for safety anyway)
svnadmin dump D:\SVN -r 35000:HEAD --incremental > tortoisedump35000-HEAD.txt

svnadmin load D:\SVN2020 < tortoisedump.txt 
svnadmin load D:\SVN2020 < tortoisedump33811-34808.txt

svnadmin dump D:\SVN -r 33811:34808 > tortoisedump33811-34808.txt

输出以下错误：

svnadmin verify D:\SVN --keep-going

r33809: E140001: zlib <uncompress>: corupt data: Decompression of snvdiff data failed
r34866: E720131: Can't set position pointer in file D:\SVN\db\revs\34\34866': An attempt was made to move the file pointer before the beginning of the file.

svnadmin dump D:\SVN -r 35000:HEAD --incremental > tortoisedump35000-HEAD.txt

svnadmin load D:\SVN2020 < tortoisedump.txt 
svnadmin load D:\SVN2020 < tortoisedump33811-34808.txt

svnadmin dump D:\SVN -r 33811:34808 > tortoisedump33811-34808.txt

现在我创建了一个新的存储库，名为SVN2020

svnadmin create SVN2020

最后，我尝试将转储加载到新的存储库中。这些运行没有问题：

svnadmin verify D:\SVN --keep-going

svnadmin dump D:\SVN -r 35000:HEAD --incremental > tortoisedump35000-HEAD.txt

svnadmin load D:\SVN2020 < tortoisedump.txt 
svnadmin load D:\SVN2020 < tortoisedump33811-34808.txt

svnadmin dump D:\SVN -r 33811:34808 > tortoisedump33811-34808.txt

我得到了这个错误，其中gp_CheckInventoryTransactions_sel.sql只是这个提交中添加的一个新文件

<<<Started new transaction, based on original revision 33811 
* editing path : trunk/Database/Company/Stored Procedures/gp_CheckInventoryTransactions_sel.sql 
...svnadmin: E160013: File not foundL transaction '33808-q35', path '/trunk/Database/Company/Stored Procedures/gp_CheckInventoryTransactions_sel.sql'

我刚收到错误信息

读取一个svndiff窗口读取超出表示结尾的内容

在windows文件资源管理器中使用OrtoiseSVN更新SVN目录时

我通过以下方式修复了它：


查找corrup目录（错误之前更新的最后一个目录/文件）
使用SVN导出，制作错误目录的副本（或从没有.SVN文件夹的其他地方获取副本）
使用SVN命令，删除错误目录并提交更改
将备份的目录复制回其来源
使用SVN命令，将目录添加到SVN结构中
提交更改

完成了

不知道这个错误意味着什么
