Description

opened on Sep 16, 2015

I renamed a (maven) project in Jenkins and the new name ended in a whitespace: "name ".
A directory "name" (*without *the trailing whitespace) was created under jenkins jobs directory.

Now the project cannot be deleted because Jenkins fails with the following message:
Trailing char < > at index 51: C:\Program Files (x86)\Jenkins\jobs\aaaaaaaaaaaaaaa _

Exception trace attached.

    • Raw content of original comment: 
      I've verified that once a job is renamed to a string with a trailing space, it can be neither deleted nor renamed again (through the UI).  Part of the problem is that the initial rename (to a string with a trailing space) fails to rename the job directory.
      


      This problem occurs only when renaming a job, and not when initially creating a job, because job names are trimmed when first created.  It seems a sensible solution would be simply to trim the given job for rename operations as well, so that the name-setting behavior is consistent across create/update operations and inadvertent leading/trailing whitespace is removed before it can cause problems.
      


      Fixed in PR #1855.

  [FIXED JENKINS-30502] trim job name upon rename
      


      If a job is renamed to a string with trailing whitespace, exceptions are
thrown as the application attempts to rename the job directory in the
file system, and the job can be neither deleted nor renamed again
through the UI. This problem occurs only when renaming a job, and not
when initially creating a job, because job names are trimmed when first
created.  This change trims the job name for rename operations as well,
so that the name-setting behavior is consistent across create/update
operations and inadvertent leading/trailing whitespace is removed before
it can cause problems.
