When you create a SVN branch , the last changed revision exist only on the parent branch or trunk. so the svn fetch fails

I had a svn trunk

The bitbake picks "Last Changed Rev: 71" when SRC_REV is $(AUTOREV) for SRC_URI and then the fetch fails.

The rev 71 exist only on the trunk not on the branch.
Comment 1 Saul Wold 2014-05-08 23:39:36 UTC 
Can you provide an external SVN server that exibits this behavior along with a 
recipe example that recplicates this issue.

Assigned to person we are requesting info from per RP.

The patch fix Unable to fetch URL bug

Follow the testing steps and instructions:

First, we need to create a svn server on the server side, eg, my is svnroot
$svnadmin create ~/workspace/svnroot

Second, on the client side:
$mkdir -p ~/workspace/svntest
$cd ~/workspace/svntest
$mkdir -p test/{trunk,branches,tag}
$mkdir -p test/trunk/tdir0/tdir1/tdir2
$touch test/trunk/hello.c
$touch test/trunk/tdir0/tdir1/tdir2/test2.c
$touch test/trunk/tdir0/tdir1/test1.c
$touch test/trunk/tdir0/test0.c

$svn import -m "create the project test" test/ svn://xxx.xxx.xxx.xxx/svnroot/test

Then, make some commit,...
Such, we now get "r15"

$svn cp -m "create a branch test_debug-1.0" svn://xxx.xxx.xxx.xxx/svnroot/test/trunk svn://xxx.xxx.xxx.xxx/svnroot/test/branches/test_debug-1.0

Now, we need to create a bb file(eg,mytest.bb) to download "tdir1" with the verion < test_debug-1.0 created time version,
eg, download r12, then in bb file has:

SRCREV = "12"
SRC_URI = "svn://xxx.xxx.xxx.xxx/svnroot/test/branches/test_debug-1.0;module=tdir0/tdir1"

Last, run fetch for mytest.bb

I have made the patch, and add the steps and instructions to test, please see the mailing list:

Comment 5 Stephen K Jolley 2014-06-23 18:00:25 UTC 
It appears that the information requested has been supplied and this should no longer be in NEEDINFO.  I have moved it to In Process Review.
Comment 6 Richard Purdie 2014-09-24 18:10:47 UTC 
I did some research into this. The issue comes from the change:

http://git.openembedded.org/bitbake/commit/lib/bb/fetch/svn.py?id=42e57e467b8334230436f24dc4bdfff64b52d2b3

I'm having a hard time figuring out what the correct thing to do here is though.
Comment 7 Richard Purdie 2021-09-20 20:41:09 UTC 
I've ended up adding a nopegrevision parameter which can be used in urls to choose the correct behaviour as there is no one correct answer that will work in every case.
