svnsync error : Error while replaying commit

[ankush chadha]

Hi All

I am encountering this svnsync error while mirroring my repository.

The target svn binaries point to 1.6.6 version(windows). I also tried running the svnsync command using 1.6.16 libraries but still getting the same error. The source repository is hosted by svn server with 1.6.6 binaries (windows).

The revision that it is trying to sync is just a copy/branch operation of a small folder (<2mb). The folder just contains text files and no binaries.

Any suggestions?


Thanks
Ankush

I think I know what the problem is

If we try to mirror a repository using a user account and if that user account has restricted access, then we will be seeing such errors.

Like in my case svnsync operation for a revision was failing that involved a copy operation if folder A to folder B. Now the user account that I used to initiate the mirror operation cannot access A. May be this is the reason why the svnsync is failing.

Is there any way to get around this problem. I updated all the permissions but the problem is that A was created like years back and I won't be able to mirror those revisions.

Access restrictions are not versioned with the data, they are read
from the configuration at the moment one wants to access the data.
Therefore it should make no difference when your folder A was created
and if the user used to sync now still can't read folder A, then your
access configuration is just wrong and needs to be tuned.

The easiest thing to test would be to create a new user just for
syncing an give him full access to everything.

Mit freundlichen Grüßen,

Thorsten Schöning

Yes, that was the problem. After fixing the permissions, I initiated another mirror operation that was able to sync everything.

The issue was that A had restricted access and a branch 'B' was created from A for public use. Since A was missing in the mirrored branch, the mirror operation failed

However even though the error happened due to incorrect authentication scripts, the error message should have included some details about the problem. When I googled for this generic error message, there was lot of crap but no solution. I had to spend almost half a day to narrow down this issue.

Thanks
Ankush

"It should work."

Specifically, if you run svnsync using an authz-bound user, then you
should just see adds-with-history converted into adds-without-history.
I believe we have regression tests for such scenarios too.

If you can reproduce this (have a minimal example), please file an
issue, thanks.

(separately: is the error in the subject really everything? It should
be logging the original error somewhere --- possibly on the server side,
but *somewhere*.)

Yeah, even I thought that the behavior should be same as you mentioned but I got "svnsync: Error while replaying commit" error during sync operation for that revision. 

When I checked the mirrored repository, A was missing which is correct as at that time A had restricted access. Branch operation of A to B failed to mirror though.

I am using svn 1.6.6. After fixing the permissions and re-initiating another mirror the problem went away and now both of my repositories are synced up with A and B. I am sure that this was the error but willl try to write reproduction steps with sample scripts.

Thanks
Ankush

That would help a lot, thanks,

I'm suddenly getting the same error:
"Transmitting file data ...svnsync: Error while replaying commit".

I'm syncing between a Ubuntu with 1.6.5 and os x 1.6.16.

I never had this error, I don't have any right issue.
I was syncing as usual, while commiting other stuffs
on the main server and suddently got this error.
I don't think the commit it is choking on has anything in particular.

Please help.
Where can I check the logs?

[ankush chadha]

Can you check the nature of the revision that is causing the svnsync to fail?

Make sure that there is enough disk space and you are able to connect to the main SVN repository. Make sure that there are no issues with the permissions (I will have to write a testcase to verify the same)

Worst case is that you have to initiate another mirror and sync the new mirror with the main svn repository.

我也遇到了该问题Error while replaying
commit，有些库用下面同样的步骤操作是没问题的，但是有些库就报这个错，不知道为什么，麻烦大家遇到过解决了的回答下，谢谢
我的操作步骤是
1、将脚本aapost-commit.bat放置到SVN主服务器相对应项目的hooks文件里，
例如：\\192.168.27.1\d$\SVN\c3m-video\hooks
"C:\Program Files (x86)\Subversion\bin\svnsync.exe" sync --non-interactive
svn://192.168.27.88/c3m-video --username admin --password cmadmin
修改下面一行中的备份服务器IP和项目名
2、将脚本Svn Start Server.bat放置在备份服务器SVN文件的同目录下
svnserve -d -r e:\SVN 修改对应的存储盘符
3、将脚本pre-revprop-change.bat放置在备份服务器相应项目的hooks文件夹下。例如：
\\192.168.27.1\d$\SVN\c3m-video\hooks
二、操作命令 (在备份服务器上操作)
1、连接 svnsync init svn://192.168.27.88/C3M-EMS svn://192.168.27.1/C3M-EMS
2、同步 svnsync sync svn://192.168.27.88/MVSS --username admin --password
cmadmin

主服务是Windows sever 2008 R2，备份服务器是Windows sever 2008 R2
SVN服务版本为Setup-Subversion-1.7.4

Hi,

you might wanna repost your question in English. I'm not sure whether anybody here can read Chinese (if it is Chinese, that is).
All I can make out of this report is that you seem to get some error running svnsync which seems to be a rather old version (1.7.4). If you want/need to stick with 1.7, I suggest you at least upgrade to the latest 1.7-version (which is 1.7.22 at the time of writing this) or even a later (and still supported) version like 1.8/1.9.
