SVNSYNC Error

[Honeylyn O. Fukuoka]

Hi,

 

I have to sync our repository to another server, so to test it, I created a test repository in my local and tried to do svnsync command to sync/mirror it.

Here's what I did:

 

1. Go to the folder where the repositories are located

2. in the cmd typed: svnsync initialize (URL of the Repository to Mirror) (URL of the Destination of the Mirrored Repo)

                  sample:  svnsync initialize svn://loocalhost/Repo Name svn://localhost/Destination Repo Name

 

ERROR:

svnsync: E16506: Repository has not been eabled to accept revision propchanges; ask the administrator to create a pre-revprop-change hook.

 

I am using Subvrsion Sever 1.7.5

 

Question:

1. Am I on the right path in creating the Mirror Repository?

2. How do I create a pre-revprop-change hook? I tried some hooks that I saw in the search engine but didn't work.

 

 

Please help me on this.

 

 

 

Thanks so much,

As error says you need to enable 'pre-revprop-change hook' in
destination repository.

Hi,

 

 

Thanks for the past response.

Can you tell me what changes do I have to make in the prerevprop-change hook?

I tried some but nothing happened.

 

 

 

Thanks,

What did you try ?

It just need to be there and should be executable nothing else

$ echo "#!/bin/sh" > hooks/pre-revprop-change
$ chmod 755 hooks/pre-revprop-change

I created a pre-revprop-change script with the single line "exit 0" in
it and put it into the hooks directory of the destination repository
(not the original repository). Worked fine on Windows. Most of the
issues that arise from allowing revision property changes are
security-oriented; if you want to prevent some (or most) users from
changing revision properties then your script must guard against it.
But if you are just creating a repository backup that no one else will
use unless the original crashes irretrievably, you don't need anything more.

Here's what I did.

I don't really know how to do it so what I did I searched then found this one.

 

Basically copy the code below into a text file and name it pre-revprop-change.bat and save it in the \hooks subdirectory for your repository.

 

@ECHO OFF
:: Set all parameters. Even though most are not used, in case you want to add
:: changes that allow, for example, editing of the author or addition of log messages.
set repository=%1
set revision=%2
set userName=%3
set propertyName=%4
set action=%5

:: Only allow the log message to be changed, but not author, etc.
if /I not "%propertyName%" == "svn:log" goto ERROR_PROPNAME

:: Only allow modification of a log message, not addition or deletion.
if /I not "%action%" == "M" goto ERROR_ACTION

:: Make sure that the new svn:log message is not empty.
set bIsEmpty=true
for /f "tokens=*" %%g in ('find /V ""') do (
set bIsEmpty=false
)
if "%bIsEmpty%" == "true" goto ERROR_EMPTY

goto :eof

:ERROR_EMPTY
echo Empty svn:log messages are not allowed. >&2
goto ERROR_EXIT

:ERROR_PROPNAME
echo Only changes to svn:log messages are allowed. >&2
goto ERROR_EXIT

:ERROR_ACTION
echo Only modifications to svn:log revision properties are allowed. >&2
goto ERROR_EXIT

:ERROR_EXIT
exit /b 1

Thanks for the link, I will try to follow the instructions there.

Do I have to just copy this:

 

#!/bin/sh
USER="$3"

if [ "$USER" = "svnsync" ]; then exit 0; fi

echo "Only the svnsync user can change revprops" >&2
exit 1

Thanks a lot,

 

 

Honey

[vishwajeet singh]

Just add one line 'exit 0' to your pre-rev-prop hook and try

if that works than you can make further changes only if required,
above may not work in your environment as I am not sure if you have
svnsync user in your environment

[Honeylyn O. Fukuoka]

When you created a pre-revprop-change, did you save it in .bak file and put it in the hooks directory of the dest repository? Am I getting you right?

My goal is to sync our repository to another server outside our country. Will this work?

 

 

Thanks,

 

 

Honey

[Honeylyn O. Fukuoka]

Okay, I will try this..
Correct me if I'm wrog, from this:

 

echo "Changing revision properties other than svn:log is prohibited" >&2
exit 1

To this:

echo "Changing revision properties other than svn:log is prohibited" >&2
exit 0

 

 

 

Thanks,

It should work , I don't see a reason why it won't work but you need
to get your setup right.

[Honeylyn O. Fukuoka]

Okay, Thanks for the help. Will try this.

Just keep
exit 0
remove everything else.

[Honeylyn O. Fukuoka]

Hi,

 

I created a .bat file with the following scripts but still didn't work:

 

1. REPOS="$1"
REV="$2"
USER="$3"
PROPNAME="$4"
ACTION="$5"

 

if [ "$USER" = "svnsync" ]; then exit 0; fi

echo "Only the svnsync user can change revprops" >&2
exit 1

exit 0

2. REPOS="$1"
REV="$2"
USER="$3"
PROPNAME="$4"
ACTION="$5"

if [ "$USER" = "svnsync" ]; then exit 0; fi

echo "Only the svnsync user can change revprops" >&2

exit0

 

3. exit 0

Did I do something wrong?

 

 

Thanks,

[Honeylyn O. Fukuoka]

I hope you are changing pre-revprop-change hook of destination repo
not the source.

[Honeylyn O. Fukuoka]

Yes, I changed the pre-revprop-change hook of the destination of the mirrored repo then saved it as pre-revprop-change.bat

The first two scripts are for Unix/Linux; they are /bin/sh or /bin/bash
scripts. They will not work on a Windows machine.

The third should have worked on any type of machine, though if the
destination repository is on Unix/Linux you will need to make the file
executable and should change its ownership to match that of the other
sample scripts in the hooks directory. For example, on my Linux-hosted
repository, all scripts are owned by user apache, group apache.

What platform is the destination repository (i.e. the backup) on? Is it
Windows or Unix/Linux? You haven't told us anything about the machines
you are running on; you mentioned ".bat files" but then tried scripts
meant for Unix/Linux.

Do NOT run any experiments with complicated scripts until you get a
simple script running; if you can't get a single line "exit 0" script to
work then none of the complicated scripts will work. In particular, if
you are not an expert batch file/shell script developer, you shouldn't
try anything fancy. You can really mess things up.

[Honeylyn O. Fukuoka]

Hi,

 

The repositories and the destination repositories are all running on windows.

Im not really an expert on batch files/shell script development...That's why Im asking for your help :(

I just followed what I was told to do here but I don't want to mess things up.

 

 

Thanks,

Here are the commands I ran on a Windows machine to synchronize from a
remote repository:

svnadmin create c:\user\work\repos
cd c:\user\work\repos\hooks
echo exit 0 > pre-revprop-change.bat
svnsync initialize file:///user/work/repos
http://repos.sourcedomain.com/repos
svnsync sync file:///user/work/repos

This ran just fine with SVN 1.6. Can you run something similar on your
Windows machine and let us know what results you get? Run the steps in
a new directory, not in the repository you just created. Note that the
source repository in my example is served by Apache, so it uses a
"http:" prefix. You would want to use a "svn:" prefix if you are using
svnserve access, as was implied by your original message.

Note that the destination repository is being accessed using the "file:"
protocol. The repository I created was not meant to be accessed by
other users; it is intended only to serve as a backup. If you are trying
to set up a write-through proxy then you will need something like
svnserve or Apache HTTP on the destination repository.

Also, depending on your repository directory names, you may need to use
quote marks around arguments. I recommend avoiding space characters in
your directory names for this test.

Thanks so much for this info, Will try this and will let you know it it is successful...

There are quite a lot of posts in this thread already, and I'm surprised
that nobody seems to have pointed Honeylyn to the relevant section of the
svnbook: http://svnbook.red-bean.com/en/1.7/svn.reposadmin.maint.html#svn.reposadmin.maint.replication.svnsync

Please read this page first, and if you have any further questions,
*then* ask on this list.

If you're also going to set up a write-through proxy see
http://svnbook.red-bean.com/en/1.7/svn.serverconfig.httpd.html#svn.serverconfig.httpd.extra.writethruproxy

Good luck!

[Honeylyn O. Fukuoka]

Hi,

 

Thanks for this.

We are using snserve not Apache...

Will this link still work with us?

 

 

 

Thanks,

I don't want to be rude but perhaps you could have checked the links before posting this question?

Sure. svnsync is just about repository replication, and has nothing
to do with what server is being used to allow access to the repository
via the network.

You didn't mention why you want to use svnsync. If your goal is to back
up a repository to another machine then all you need is svnsync.
If the goal is to set up a write-through proxy using the mirrored repostory
then you need svnsync and Apache HTTPD because svnserve doesn't support
write-through proxying.

Yes (please read the links to the documentation you've been provided).
But not with an HTTP URL for your source repository. If you're using
svnserve, your URL should be svn://

[Honeylyn O. Fukuoka]

Hi,

 

The reason why I am doing the svnsync is to backup our repository to our new server in our main branch.

 

 

Thanks,

 

 

Honey

[Honeylyn O. Fukuoka]

Hi,

 

I tried the one in your link under repository replication and followed what was instructed there.
I also changed the pre-revprop-change hook script based on the example given there and so as the start-commit hook.

But when I performed the 'svnsync initialize' command, I got this error:

     svnsync: E170001: Authorization Failed

 

Here are the scripts I put in the pre-revprop-change hook

#!/bin/sh

USER="$3"

if [ "$USER" = "syncuser" ]; then exit 0; fi

echo "Only the syncuser user may change revision properties" >&2
exit 1

And for the start-commit hook:

#!/bin/sh

USER="$2"

if [ "$USER" = "syncuser" ]; then exit 0; fi

echo "Only the syncuser user may commit new revisions" >&2
exit 1

Those are exactly the same scripts that was on the book.

I also did what David told me to do, to create another pre-revprop-change hook script with 'exit 0' and save it in .bat but also received the same error.

 

Can anyone tell me what should I do to succesfuly erform the initialize command?

 

 

 

Thanks so much,

 

 

Honey

If all you are doing is a one-off move, then you should also investigate using dump/load. Depending on the size of your repo this can take a while, but can be done without svnsync and can have advantages in having your shiny new in the latest format.

I suggest that you read the manual, especially this bit about "Migrating Repository Data Elsewhere":-

http://svnbook.red-bean.com/en/1.7/svn.reposadmin.maint.html#svn.reposadmin.maint.migrate

pre-revprop-change is enough, start with the easiest setup possible.

This has nothing to do with hooks, I suspect you provided wrong user
credentials to the source repo. Check that the provided user on the
command line is the same as stated in passwd file of the source repo.

> Here are the scripts I put in the pre-revprop-change hook
> #!/bin/sh

I'm rude now, but please concentrate on your problem! I only had a
fast look over the messages in this thread and found more than one
message telling you that hooks starting with #!/bin/sh are for Linux,
not for Windows. They won't work, don't do that, ignore each and every
hook starting with that line. It's wasted time, confuses you and even
the people who try to help you. You want to sync either to Windows or
Linux, I read Windows and therefore you won't need to do anything
starting with #!/bin/sh.

Please delete those files you created and simply forget about them.
:-)

> Those are exactly the same scripts that was on the book.

But the book has a paragraph noticing that one has to adopt the
procedure on Windows on it's own.

Because you don't even get where the hook could be used. But the
creation of this and only this one hook is fine and what you need.
Only this hook with the line "exit 0" as pre-revprop-change.bat.

> Can anyone tell me what should I do to succesfuly erform the initialize
> command?

Check the login credentials for the source and maybe even the
destination repo, depedning on how you access the destination. Provide
us the exact command line you ran for initialize, just without
passwords of course.
