Post by derhexer » Tue Mar 25, 2014 5:51 pm

Hi,

What happens if you enter this URL address into a web browser:

Code: Select all

https://dellxps/svn
This page says the following regarding 405 errors:
Fixing 405 errors - general

405 errors often arise with the POST method. You may be trying to introduce some kind of input form on the Web site, but not all ISPs allow the POST method necessary to process the form.

All 405 errors can be traced to configuration of the Web server and security governing access to the content of the Web site, so should easily be explained by your ISP.
This hints it might be a security or access control issue causing the 405 response.

If i enter the URL address into my chrome browser, i get "The site's security certificate is not trusted!" message.
After confirming and login, i see the svn directories as known.

Additional info:

Access to

Code: Select all

https://dellxps/svn
via browser is not always possible. The most time no side will appear, no 'site's security certificate' warning appears, no time out side warning appears, nothing, i dont know why.
But if i use the

Code: Select all

https://192.168.0.123/svn
format i will be connected immediately.

The TortoiseSVN Repo Browser works on the same machine with

Code: Select all

https://dellxps/svn
address format perfectly (username and password is entered and remembered by TortoiseSVN Repo Browser correctly).

Now i added the hostname with ip address to my local ipfire host table, so every browser can resolve the https://dellxps/svn correct and immeditely, but AgentSVN connect with the same error as shown in my first message.

When will AgentSVN ask for the connect infos (username and password)?
Dismiss AgentSVN the security certificate warning automatically?

Current state
Now i can connect the Agent SVN to VisualSVN Server... but only if i do not use the root of all repos.

Following address will be not connected:

Code: Select all

https://dellxps:443/svn
Following address will be connected:

Code: Select all

https://dellxps:443/svn/SomeRepo
But if i want add a project 'test' via Visual C ++ 6.0 -> Add to Source Control following error appears after correct "Subversion User Login".

Code: Select all

Agent SVN
https://dellxps:443/svn/SomeRepo/test
The project URL shown above already exists in the SVN repository.

and the log

If i enter the URL address into my chrome browser, i get "The site's security certificate is not trusted!" message.

This indicates the issue relates to the connection being refused based on authenticate grounds.
The most time no side will appear, no 'site's security certificate' warning appears, no time out side warning appears, nothing, I don't know why.

If the browser can't connect then there is not much chance of the SVN client running from the command line, using the exact same authentication details managing to connect :(

The authentication process should be the same for both systems.
The TortoiseSVN Repo Browser works on the same machine
Has TortoiseSVN been configured with some pre-configured user id and password details?

It sounds like TortoiseSVN is providing the correct authentication details and hence it has no trouble connecting.
svn: E215004: Authentication failed and interactive prompting is disabled; see the --force-interactive option

This suggests to me the authentication is failing.

Now I have never used Agent SVN with SVN Server so this could well be a new issue.

But it could also be an access control setup issue and the server is just failing the connection based on authentication :?

What should happen when there is an authentication issue is the server responds with a login failure.

Agent SVN will then prompt with a login dialog and it will then use those user/password details for the remainder of the session to authenticate all requests with the server.

That process works fine for the both the stock standard SVN server setup and the Apache SVN server setup.

Cheers Jussi

You can see in the log, there is an attempt to connect with a user MyUserName (in real my logon name on the machine) this fails.
Then a login prompt appears. I enter my VisualSVN Server username (derhexer) and the password. The following login is successful (see log).

The last entries in the log results with 0 (means this ok?).

Code: Select all

But why popup a Agent SVN error dialog with the error message, that the URL already exists? The SomeRepo folder on the server is empty and all users have read/write access.

The VisualSVN server works fine with the VisualSVN- and TortoiseSVN client.


For better understanding:

The VisualSVN server is normally accessable via

Code: Select all

https://dellxps/svn
or

Code: Select all

https://dellxps:443/svn
Because the need of Agent SVN to access to existing repository in the Configuration Details dialog, i added an empty repository 'SomeRepo' to the VisualSVN Server (manually, this is standard way).
Now AgentSVN accept the configuration

Code: Select all

https://dellxps:443/svn/SomeRepo
In Visual C++ 6.0 the project 'test' will be a sub directory of

Code: Select all

https://dellxps:443/svn/SomeRepo


Maybe this is the problem.
Normally a repo is saved in his own namespace (directory) and not in sub directory of another repo.

Yes.
But why popup a Agent SVN error dialog with the error message, that the URL already exists?

The URL is made up of the SVN Repo Location + the project folder location.

It sounds like you are adding a new project and that URL is already taken.
The SomeRepo folder on the server is empty and all users have read/write access.

That does not matter.

If you are adding a new project then because it is a new project then it can not exists as a URL.

The new URL will be created.

So if the URL does already exist then it is not a new project.

There are two ways to work with projects in MSSCCI.

You can add new projects or you can bind to existing project (see the help file for details on binding).
But if I want add a project 'test' via Visual C++ 6.0
By this do you mean you are using the very old Visual C++ 6.0 from the late nineties.

If you are then you might also be seeing a problem between Visual C ++ 6.0 and Agent SVN.

The last time Visual C++ 6.0 and Agent SVN would have been several years ago and Agent SVN has changed a lot since then.

If you are indeed using that 1996 version Visual C++ 6.0 what I would suggest is first trying a simple test using the file:// protocol and a local repository.

That test should only take 5 minutes and would go something like this:
  1. Set up Agent SVN using the file:// protocol
  2. Set the repo location to something like: c:\temp\repo
  3. Let Agent SVN create the repo at this location
  4. Turn on the debugging
  5. Start Visual C++ 6.0 and create a new test project
  6. Try to add that project to Agent SVN
  7. TortoiseSVN at the file://c:\temp\repo repo and you should see the results

Using local repo works fine. The reason we bought Agent SVN was the full support of Visual Studio C++ 6.0 from the late 90th :)...
We have to support many applications based on that release.

Now i know that Agent SVN do not support Visual C++ 6.0 to be connected to an VisualSVN Server. As a workaround (and usable solution) we defined a virtual drive connected with a remote nas directory.

Maybe you add this info to your Agent SVN web description.

Any way: A big thanks for you fast and really professional support!

Using local repo works fine.
It is good to know Visual Studio C++ 6.0 works at least in local mode and its good that you found a work around :)

If you want to send me a full debug file log (see e-mail button below), I'd be glad to take a closed look.

I suspect the problem might be that VisualSVN Server is responding with a different reply to the standard SVN Server and that might be causing the issue.

A full debug log file should help show that and it might even be possible to fix this.

Now i know that AgentSVN do not support Visual C++ 6.0 to be connected to an VisualSVN Server
I tried to replicate this issue, but for me Visual C++ 6.0, VisualSVN Server and AgentSVN are working without error :(

This is what I did:

1) I was running the latest AgentSVN version found here: http://www.zeusedit.com/agent/bin/asvn-v237.zip

As this is the latest version, this version would be later than yours but I'm not sure if this difference is the issue :?

If possible it would be best to try out this latest version.

2) In VisualSVN Server I create a Test1 repository:

Code: Select all

https://zeus/svn/Test1
3) I then permissioned that repo with a user ID and password.

4) I then set up AgentSVN to point it to that new repo:

Image

5) I then create a MyVCPP test project and from inside of Visual 6.0 C++ I added that to source control using AgentSVN. That worked as shown below:

Image

6) I then checked out a file for edit and that also worked:

Image

I could also check in, undo check out and difference the file without issue.

So for me everything is working just fine :?

Cheers Jussi
