svn (1.11) update shows warning W170013

[GerdP]

I get this warning since a few days. Is this something I have to fix on my machine?

Either it is a temporary GitHub issue with the git→svn interface or the target changed again.

Both happens from time to time.

[GerdP]

Happens always on both my machines, also with some plugins. You don't see those messages when doing svn up?

[stoecker]

ATM: No

[GerdP]

OK, maybe my svn client is the problem. I'll try with an older version. My current version is

D:\josm\core>svn --version
svn, version 1.11.0 (r1845130)

[GerdP]

Yes, older version works without problems:

SVN externals using Github mirrors is not always working as it should be... Some hint and tips that can help when the error occurs:

• svn clean
• delete the externals folder, then svn up
• ultimately delete everything and svn co...

We should get rid of this problem after #16944 #16871 and #16857

[Don-vip]

I'm using SVN 1.10.2 so maybe this is a regression from 1.11?

[Don-vip]

Yes, 1.11 is incompatible with Github bridge:

​https://subversion.apache.org/docs/release-notes/1.11.html#issues

Github's SVN Bridge server implementation incompatible with SVN 1.11

​Issue #4789

As of November 2018, Subversion 1.11 clients are unable to check out repositories from Github. Stricter DAV RFC conformance checks were added to SVN 1.11 clients, and Github's custom SVN server implementation happens to not conform to the newly expected behaviour. We are waiting for Github to resolve the issue at their end. In the meantime, Subversion 1.10, and perhaps even the Git version control system, can be used as a workaround.

[Don-vip]

Subversion 1.10 is a LTS release and still supported, so best is to keep this one until Github fixes the issue.

[Don-vip]

According to ​SVN developers Github fixed the issue. Can you please check?

[GerdP]

I can confirm that svn 1.11.0 no longer shows the error messages. I did an update with 1.10 short before so I did not see any actual change.
