Re: Show log - Item is not readable error

regarding this, and your other messages in this thread:

first, you certainly have to read the Svn Book,

It is pointless to explain here from scratch what is already written
in that good book.

If you searched, found, and but still do not understand
some wording, feel free to ask.

second, on original your question

The book mentions that
"The UUID is the repository's universal unique identifier. The Subversion
client uses this identifier to differentiate between one repository
and another."

The UUID is used to identify working copies that are retrieved from
the same repository, and to tell apart those that are from different

Certain commands are valid only if their source and destination are
from the same repository. Even if those working copies were created
by independent checkout operations, or whatever. As they are still
from the same repository, operations on them are valid.

URLs might change, or there might be several repositories on similar
URLs, but UUID remains the same.

The UUID is randomly (uniquely) generated when you create a
repository with "svnadmin create" command. You may change it in
svn 1.5 by using "svnadmin setuuid", and by loading a certain dump
file in previous versions.

Each working copy (each .svn/entries file in the working copy) remembers
the UUID of the repository where it was retrieved from.

Once you change UUID of the repository, all working copies must be
discarded by your users and re-retrieved anew.

Regarding TortoiseSVN and its Log view:

since version 1.5.0 Tortoise does have a cache for certain information
retrieved from the repository - the cache of log messages. That cache
is keyed by repository uuid.

Once you change the id, you must flush the cache, that can be done
from certain page of the Settings dialog.

Best regards,
Konstantin Kolinko
