Bad URL passed to RA lay

Bad URL passed to RA lay

[m.skoric]

Hi List,

i have a problem with git-svn clone / fetch. I get following error while doing one of previous command -> "Bad URL passed to RA lay"
This happens because a branch doesn't exists in svn anymore and git wants to retrieve data from it. Here is the complete error message

Initializing parent: Abo-Uebernahme (Bug #994)@341
Found possible branch point: "quoted"..trunk => "quoted"...Abo-Uebernahme (Bug #994), 203
Found branch parent: (Abo-Uebernahme (Bug #994)@341) bb831869748c98bf97d105c5894ae65331c95c08
Bad URL passed to RA layer: Malformed URL for repository at /usr/bin/git-svn line 4311

git version 1.6.3.3

Aynone else has this Problem?
Can anyone help me?

Thanks in advance

Majk

Hi,

Unlikely, not many people use URIs as weird as yours :)
The existing test case (t9118) we have was also inspired by you,
on the same branch, even.

> Can anyone help me?

What exactly is the "quoted" you refer to?  That's not an actual branch
name, is it?

Can you try it with v1.6.5?  You might need to edit your $GIT_CONFIG,
but commit 5268f9edc3c86b07a64fcc2679e5ffe39be28d97 was the last
fix for URI-escaping problems:

  Author: Eric Wong <normalperson@yhbt.net>

    svn: assume URLs from the command-line are URI-encoded
    
    And then unescape them when writing to $GIT_CONFIG.
    
    SVN has different rules for repository URLs (usually the root)
    and for paths within that repository (below the HTTP layer).
    Thus, for the request URI path at the HTTP level, the URI needs
    to be encoded.  However, in the body of the HTTP request (the
    with underlying SVN XML protocol), those paths should not be
    URI-encoded[1].  For non-HTTP(S) requests, SVN appears to be
    more flexible and will except weird characters in the URL as
    well as URI-encoded ones.
    
    Since users are used to using URLs being entirely URI-encoded,
    git svn will now attempt to unescape the path portion of URLs
    while leaving the actual repository URL untouched.
    
    This change will be reflected in newly-created $GIT_CONFIG files
    only.  This allows users to switch between svn(+ssh)://, file://
    and http(s):// urls without changing the fetch/branches/tags
    config keys.  This won't affect existing imports at all (since
    things didn't work before this commit anyways), and will allow
    users to force escaping into repository paths that look like
    they're escaped (but are not).
    
    Thanks to Mike Smullin for the original bug report and Björn
    Steinbrink for summarizing it into testable cases for me.
    
    [1] Except when committing copies/renames, see
        commit 29633bb91c7bcff31ff3bb59378709e3e3ef627d


And if git v1.6.5 doesn't work, would you mind looking at (and possibly
modifying) the t9118 test in git to reproduce since it's already got your
oddly-named branch in it?   Thanks!

Ye, i know ;) This is really old stuff and we already changed them to more sane ones ;)

ah brainfart.

This info is essential!

quoted = branches/dirk/Abo-Uebernahme... => https...branches/Abo-Uebernahme...

This is not a URI Escaping Problem. As i allready mentioned: I think its a svn
problem and git can't handle that.

svn History:

r203 svn copy /trunk/ /branches/dirk/Abo..
r204 svn mv /branches/dirk/Abo..   /branches/Abo..
r341 svn mv /branches/Abo.. /branches/0944-Abo..

r203 branch was created from trunk.
r204 branch was moved from /branches/dirk/ to /branches
r341 branch was renamed to 0944-Abo

This is what git does.

I think the problem is that git doesn't like this kinda action.
branch -> do something with branch -> rename branch.

After some debugging i found something in git-svn

sub find_parent_branch
{
...
	} elseif ($self->ra->trees_match($new_url, $r0, $self->full_url, $rev))
	....
}

the trees_match sub doesn't do any error handling. if $self->full_url doesn't
exits anymore this will fail, right? 

I don't know if the followong piece of code in find_parent_branch works like
you expect it!?

>        $SVN::Error::handler = $err_handler;
>}
>return undef unless defined $paths;

Maybe its just a problem with renaming branches or something!?
My Perl knowledge is really limited, so its up to you my friend ;)
