SVN 1.4.6 support exit codes

[Charan]

Hi,

does SVN support exit codes. Suppose if I use "svn merge" in my shell
script, will svn be able to return exit code "0" if the merge is successful.


Thanks,
Charan

Re: file:/// protocol based svn repository questions

[David Weintraub]

You should NEVER use the file:// protocol unless you are the only
person using the repository, and the repository is only accessible by
you.

The file:// protocol requires read and write permissions on all files
in the repository for the user who is doing the committing. This means
that instead of using Subversion commands, the user can munge the
repository directly. For example, the user could copy the repository,
manipulate the items in it, and then replace it with the munged copy.

Even worse, if user "bob" does a commit, the version file is now owned
by "bob", and if the rights aren't setup correctly, only "bob" might
be able to read and write that version.

I don't know if there are concurrency issues, but I don't even use
file:// when I am creating my own temporary repositories.

I understand why you may not want to use Apache's http as your server.
That can be a bit of a bear to setup. However, the svnserve server is
quick and simple to setup. It is definitely easier to use than shared
Windows directories and affords you full client/server protection.

You should seriously consider not using the file:// protocol.

NTLM proxy authentication credentials

[Carsten Fuchs]

Hi all,

using svn-1.6.6 on Windows Server 2003, I experience the same problem as 
described by Yann Eads at

http://svn.haxx.se/dev/archive-2008-02/0693.shtml

In summary, proxy authentication via NTLM fails, because even though the proxy credentials are 
properly specified in the "server" config file, i.e. like



[global]

http-proxy-host = ...
http-proxy-port = ...
http-proxy-username = ...
http-proxy-password = ...


these credential are not used in the NTLM replies (but instead those of the 
Windows user login).

Anything that can be done about it?
I'd be very grateful for any help.

Best regards,
Carsten

PS: I was able to come up with a work-around, using 
http://cntlm.sourceforge.net/ ...

user2 is trying to copy /trunk/specialfile to somewhere where he'd
be able to read it.  So Subversion blocks it.  In order to create
a branch from trunk, you need read access to trunk and every file
inside it.

Perhaps /trunk/specialfile can be moved somewhere else, so you can
remove this restrictive permission?  (This may require you to dump
the repository and use "svndumpfilter" to get rid of the historical
revisions of /trunk/specialfile).

Kind regards,
 
Jon

Subversion doesn't track permissions like you're wanting.

Maybe have your build/export script set the permissions as part of your process?

Subversion doesn't track/manage permissions beyond +x (executable).

If you're connecting to a SAMBA share from Windows and doing an export
there, it's down to your SAMBA configuration.

SVN and Windows/Linux permissions

[Jeff.Drake]

This might not really be a SVN question, but somebody may have encountered it. 
I need to be able to export code from windows hosted SVN (Apache/2.0.58 (Win32) 
DAV/2 SVN/1.3.1) and maintain linux permissions set by linux clients at commit 
time.   I typically get permissions that omit the group and other permissions, 
like so:

Y:\ls -altr

Do I *have* to dl to a linux partition, will windows always strip some unix 
permissions?

Great, that's very much appreciated!

If you haven't done so, you might want to peek into the community

If you have questions, just ask! If you have patches, please send them.

Very bad idea. When you do this, anyone can corrupt or even delete the
whole repository with one errant keystroke. And you have no path-based
authorization. If someone uses a newer client with the repository,
older ones may not be able to read it. There /may/ be concurrency
concerns as well, but I'm not 100% sure on that.

Have a look at the final bullet point on
http://svnbook.red-bean.com/en/1.5/svn.serverconfig.choosing.html

Set up a proper SVN server, you'll be much better off.

file:/// protocol based svn repository questions

Hi all,

 

We're using SharpSVN.SvnReposito​ryClient.CreateRepos​itory to create file:/// 
protocol based svn repositories on shared Windows network drives. Can anyone 
tell me the exact permissions a Windows user will need to fully interact with 
the repository? We're recently run into a user that was able to lock a file but 
couldn't do a commit, the error indicated that the commit failed and a .tmp 
file couldn't be moved since it already existed in txn-current? The customer 
indicated that they had read and write access??

 

Also, I've seen quite a few posts on the Internet suggesting that sharing a 
file:/// protocol based svn repository is not recommended for multiple users 
and even discouraged. Can anyone confirm or refute this information? 

 

Thanks!

It's possible. Just make sure to install both into a different prefix.
E.g. if you build from source, install both into separate prefixes:
For 1.4.5:
  ./configure --prefix=/usr/local/svn-1.4.5
For 1.6.9:
  ./configure --prefix=/usr/local/svn-1.6.9

E.g. on my system I currently have two svn trunk builds, and one 1.5.x
build (the branch from which the next 1.5 release will be made, if ever)
and one svn-1.6.x build (the branch from which the next 1.6 release will
be made) installed in my home directory:

$ ls ~/svn/prefix
apr/ httpd/   serf/svn-1.5.x/   svn-trunk/
bdb/ neon/sqlite/  svn-1.6.x/   svn-trunk2/
$ which svn
/home/stsp/svn/prefix/svn-trunk/bin/svn

If you use binary packages, the content of binary packages will probably
overlap, e.g. both trying to install /usr/bin/svn. In this case you cannot
install both at the same time (unless there is a way to install an RPM into
a different directory than the root directory '/' --  I don't know if
that's possible).

I think this is a known issue. You have to give user2 read access to the root

between user1 and user2. User1 has rw access to /.

Yes, first you compile the thing:

 ./configure --prefix /path/to/folder/for/svn-1.6.9
 make install

Then, you only need to adjust your PATH and LD_LIBRARY_PATH so that the other 
location is found. This is also useful if you don't want to (or can't) 
install it systemwide (yet). You can install it in your home directory and 
don't screw up your system in case of mistakes, you don't even need root 
privileges.

Installing two subversion release on the same machine

[Emiliano . MONACO]

Hallo,

I'm new comer in Subversion users mailing list and I want post my first 
question:
I have Subversion 1.4.5 release up and running over a Linux CentOS 
machine. Due to I would like to upgrade Subversion to 1.6.9 release, I 
would like to know if it is possible to install two Subversion release on 
the same machine without performing upgrade of the old one.

Regards,
Emiliano.

403 Forbidden in response to COPY request

Several users are configured to use our Subversion system via HTTPS and Basic 
authentication.

Repos URL:
https://www.example.com/repos/repos1/trunk


Apache config "vhost_ssl.conf":


DAV svn
SVNParentPath /var/www/svn

AuthzSVNAccessFile /var/www/vhosts/example.com/conf/reposAccessFile

AuthType Basic
AuthName "Traffic Subversion Repository"
AuthUserFile /var/www/vhosts/example.com/conf/svnuserpw
require valid-user



reposAccessFile:

[specialrepos:/] 
* = rw

[specialrepos:/trunk]
user2 =

[specialrepos:/branches]
user2 =

[specialrepos:/tags]
user2 =

[/trunk/specialfile]
user2 =

[/]
* = rw 


svnuserpw file:
user1:
user2:


When I authenticate as user1 I can execute all commands without problem.  
However, when I authenticate as user2 I receive the following error when trying 
to create a branch from the trunk of "repos1":

Using TortoiseSVN from my local machine:
> Copy C:\www\repos1 to https://www.example.com/repos/repos1/branches/test, 
> Revision 999
Server sent unexpected return value (403 Forbidden) in response to COPY request 
for '/repos/repos1/!svn/bc/999/trunk'

Using the command line from my local machine:
> svn copy --username user2 https://www.example.com/repos/repos1/trunk 
> https://www.example.com/repos/repos1/branches/test -r 999 -m ""
> svn: COPY of branches/test4: 403 Forbidden (https://www.online-toolbox.com)

It works if I do it on the command line of the same server where the repos is 
actually stored, and I'm logged in as root:
> svn copy --username user2 file:///var/www/svn/repos1/trunk 
> file:///var/www/svn/repos1/branches/test -r 999 -m "" --no-auth-cache
> Committed revision 2000.

but fails if I'm logged in on that same server as another user:
> svn copy --username user2 file:///var/www/svn/repos1/trunk 
> file:///var/www/svn/repos1/branches/test -r 999 -m "" --no-auth-cache
> svn: Can't create directory '/var/www/svn/repos1/db/transactions/1999-1.txn': 
> Permission denied
but this is presumably because only the "apache" operating system user has 
write access to the /var/www/svn folder:

drwxr-xr-x  123 apache apache4096 Jan 1 2010 .
drwxr-xr-x  1 root   root  4096 Jan 1 2010 ..
drwxr-xr-x  12 apache apache4096 Jan 1 2010 repos1
drwxr-xr-x  12 apache apache4096 Jan 1 2010 specialrepos


I can't see what makes user2 different from user1 other than the configuration 
in reposAccessFile which only concerns an unrelated repository ("specialrepos") 
and a single file which exists in all repositories ("/trunk/specialfile").

I'm using:
TortoiseSVN 1.6.5, Build 16974 - 32 Bit , 2009/08/20 08:13:46
Subversion 1.6.5, 
apr 1.3.8
apr-utils 1.3.9
neon 0.28.6

Any advice will be much appreciated!

Re: Error "An existing connection was forcibly closed by the remote host" with F5 content switch or working copy on shared drive

[Les Mikesell]

This sounds like the checkout is just slow in creating files, triggering server 
timeouts that are probably configurable.  When talking directly to the server, 
this should be controlled by the apache 'TimeOut' directive which defaults to 
300 seconds.  It is also possible for intermediate NAT or firewall devices to 
time apparently inactive connections out but normally they would have a much 
longer timeout for tcp connections.

For the server side everything is handled by the Apache httpd process 
and our mod_dav_svn just receives the pre-parsed requests; so no tcp

So I don't think the Subversion project can really fix this for you (as

Hi,

I'm trying to understand why the following error occurs.

body: An existing connection was forcibly closed by the remote host.

I've seen this error in a couple of scenarios:
1) when performing a checkout on a Windows box with the working copy 
stored on a drive mapped to a NAS share
2) when performing a checkout on a Windows box and the server is an F5 
content switch that just redirects traffic to the Subversion server


The first scenario is of less concern to me, but I mention it anyway 
since I think it is the same problem.


For the second scenario, I worked with someone on our networking team to 
understand the problem.  What he discovered and how he "resolved" it 
with our F5 content switch can be found below.  The server is running 
Solaris 10, Subversion 1.6.6, Apache 2.2.11, and repositories are served 
via HTTP.  The client is running Windows XP SP3 and Subversion 1.6.7 
(error occurs with TortoiseSVN as well), but the error also occurs on 
Windows Server 2003.  I haven't tested any other Windows client OSes and 
haven't seen the error on UNIX, but suspect the underlying problem may 
exist there and the OS handles it more gracefully.  Here is the 
explanation by my networking contact.




The problem that is presenting is that the client's receive buffer is 
filling up and staying full for a long period of time.  When this 
occurs, he advertises a tcp window size of 0 in packets he sends to the 
destination F5.  This also happens when he goes directly against a 
server.  The server seems to tolerate it while the F5 does not. 

 

Last year,  I took traces of the traffic against the server by the 
client directly, and through the F5, and saw that the server was seeing 
different MTU and options from the F5.   I modified the standard TCP 
profile on the F5 to have it proxy the TCP options the client offered so 
the server would get them.  I also set it to proxy the MTU setting the 
client offered. This seemed to have fixed the problem at that time.  But 
your current testing failed. 

 

Upon closer inspection, I determined that the F5 was resetting the 
connections, not the server as I had previously thought.  This time, I 
turned off those two options from last year and increased the Maximum 
Segment Retransmissions from the default of 8 to 16.  This controls the 
number of times the F5 resends a packet after it gets no response.  This 
also controls the zero window probes he sends to see if the client can 
receive data yet.  TCP uses a back-off algorithm and increases the time 
between retries.  With 8 attempts, the total retry time is just over a 
minute.  I suspect retries of 16 will cause it to retry for 5 or 10 minutes.


 

I would really like to get this in front of SVN developers, because 
something is getting hosed on the client that causes him to stop pulling 
off the receive buffer.  If the zero window lasted 10 seconds or so, it 
would not be a problem.  But for him to in effect go offline for over a 
minute is, I believe, a bug.  We can just assume that the reason the

or it might just retry more than 8 times by default.  Might be a question for 
the UNIX team as to the retry count.  If we get some time, we could do some 
packet captures and find out for certain.

 

Yesterday and today, I did a few other things that did not help.  I increased 
the TCP receive buffers on the client side sessions, then on the server side 
sessions, then both.  I then turned off all of the tcp options in the F5 
default TCP profile.

Re: Cannot accept 'svn:sync-lock' property because it is not encoded in UTF-8

[Daniel Shahaf]

svn:sync-lock is set by svnsync as follows:

  apr_err = apr_gethostname(hostname_str, sizeof(hostname_str), pool);
...
  mylocktoken = svn_string_createf(pool, "%s:%s", hostname_str,
   svn_uuid_generate(pool));
...
  /* Except in the very last iteration, try to set the lock. */
  SVN_ERR(svn_ra_change_rev_prop(session, 0, SVNSYNC_PROP_LOCK,
 mylocktoken, subpool));

I suppose either _gethostname() or _uuid_generate() return a non-UTF-8 
string for you.

For the short term, you could either change the hostname (assuming that's 
the problem) or hack svnsync so it generates the lock token differently.  
For the long term, we'll have to make sure the 'mylocktoken' is always 
valid UTF-8. (e.g., what is the encoding of hostname_str?)

Yes, I know that, but svn:sync-lock is a system property added by
svnsync during synchronization, to keep the target repository locked.
How do I re-encode it?
