Hello Daniel, I will check if there is a Virus checker interacting.
> there is sufficent time to complete the scan so you don't notice? it does not matter if i wait 10 seconds or 2 hours. relevant is that TurtoiseMerge is open while i update by script again. so to me it looks like Turtoise is locking some data/files and releasing it first when i close it. the result of your testing batch is the following: L:\TestProject>test_svn_lock.bat L:\TestProject>svn up Updating '.': U branch\2.2.6\TestProject\src\eDef.pas U branch\2.2.6\TestProject\src\eDes.pas U branch\2.2.6\TestProject\src\eTyp.pas U branch\2.6.1\TestProject\src\eCon.pas U branch\2.6.1\TestProject\src\eDefs.pas U branch\2.6.1\TestProject\src\eDesCtrls.pas U branch\2.6.1\TestProject\src\eTyps.pas U trunk\src\eCon.pas U trunk\src\eDef.pas U trunk\src\eDes.pas U trunk\src\eTyp.pas U trunk\TestProjectTester.src\Tests\UnitTests\Test_7686.pas Fetching external item into 'ASL': Updated external to revision 1062.

Juli 2021 20:10 I tried to reproduce the problem with exclusive-locking = true. I get another error message in this case, E200033: [[[ C:\Devel\test>svn up svn: E200033: Another process is blocking the working copy database, or the underlying filesystem does not support file locking; if the working copy is on a network filesystem, make sure file locking has been enabled on the file server svn: E200033: sqlite[S5]: database is locked, executing statement 'PRAGMA case_sensitive_like=1;PRAGMA synchronous=OFF;PRAGMA recursive_triggers=ON;PRAGMA foreign_keys=OFF;PRAGMA locking_mode = NORMAL;PRAGMA journal_mode = TRUNCATE;' C:\Devel\test> ]]] So it seems Subversion is properly detecting that the database is already locked (as indicated by the error code 5, SQLITE_BUSY, see [1]) and give another error message. In fact, E200030 is a fallback meaning "Sqlite returned an error for which we don't have a specific Subversion errorcode" [2]. That being said and combined with the fact that the error is intermittent, makes me wonder if you might have a problem with an antivirus/security software. Maybe TortoiseSVN is updating the database, which is caught by the security software triggering a scan, then when you run `svn up` the database is still locked exclusively by the security software. When you close TortoiseMerge, there is sufficent time to complete the scan so you don't notice? (I personally hate this explaination, but I've run into strange bugs where things start to work after some whitelisting, maybe whitelist the wc.db file?). To test you could probably write a batch file along the following lines and run in a test wc. [[[ svn up echo "foo" >>test svn add test svn ci test -m test1 svn up echo "bar">>test svn ci test -m test2 svn up ]]] Kind regards, Daniel Sahlberg
