Redmine

Looks like a bug.

Could you fill in a defect for this, please ?

And try this workaround : replace "@target_project.reload" with "@target_project.reload if @target_project" in your file lib/tasks/migrate_from_trac.rake at line 685.

Thank you very much for your answer.

I fixed the code row an now it works. I also have found a ticket, were the problem was described:

"The Target project identifier sould be given in lowercase":

Ticket: http://www.redmine.org/issues/5764

But now I have a new problem:

c:\Program Files (x86)\Redmine>rake redmine:migrate_from_trac
(in c:/Program Files (x86)/Redmine)

(See full trace by running task with --trace)

This problem was also described in the Ticket http://www.redmine.org/issues/5764.
I modified the RAKE-File "migrate_from_trac.rake" which the given solution, but the problem still exists.

I am using the trac version 0.12dev-r9347 with the sqlite version 3.5.9.
In Ruby I installed the sqlite version 3.7.3. Is it possible, that this is the problem?

Best regards, Beppo

If you're sure you patched correctly your installation, could you please post the exception trace by running again rake... with --trace ?

Here is the log, but I think where the problem is. Because I changed the file migrate_from_trac.rake in the directory C:\Program Files (x86)\Redmine\lib\tasks but this changes were not apply.

What I have to do, that the changes in the rake-file supply? Do I have to restart the server?

I don't think it's necessary, what do you mean with "this changes were not apply" ?

For example I changed the line print "Migrating milestones" in the migrate_from_trac.rake to print "Migrating milestones New Text ..."

But when I start the script over cmd (rake redmine:migrate_from_trac), the consol shows me "Migrating milestones" instead of "Migrating milestones New Text ...".
So I think that ruby doesn't use my changes I have made.

Weird. I doubt that ruby use some cache or compilation mechanism between 2 executions of the same script, though.

I don't know what was happening, but after a restart it works. Now all the changes were used by ruby.

Thank you very much for your help.

Best regards, Beppo

I run into the same problems.
- migrating the milestones fails, but I was able to fix that with the link in this topic (http://www.redmine.org/issues/5764)
- migrating the tickets fails, with the same message as Josep S posted => "bignum too big to convert into `long'", but on a different row
