into referent file/dir.
Example of links which fail to convert to referent files:

File exceeding 32 chars gets transformed into file with less than 32 chars,
check file sizes.
in example:
- 0830348-PULSERASROJASCAP1-Y.index has been transformed to wrong file
0830348-PULSERASROJASCAP1-Y.data instead.

--- Comment #1 from Wayne Davison <wayned at samba.org> 2014-05-26

The command you ran was a copy of rsync -L 0830348-PULSERASROJASCAP1-Y.data
0830348-PULSERASROJASCAP1-Y.index, so you told it to copy the contents of the
data file onto the index filename (replacing the symlink) which is what it did.

https://bugzilla.samba.org/show_bug.cgi?id=10568 --- Comment #2 from David Levy <levy.david at gmail.com> 2014-05-26 21:35:15 UTC --- Running rsync -L Should convert each link in directory to it's referent file, when the filename exceeds 32 chars that fails. This is easy to test, don't just resolve cause that fails. Let me know if you have different results.

https://bugzilla.samba.org/show_bug.cgi?id=10568 --- Comment #3 from Wayne Davison <wayned at samba.org> 2014-05-26 21:57:53 UTC --- If you were expecting the destination symlink to be followed, that is not how rsync works. The -L option just affects source symlinks, and the -K option just affects destination symlinks to directories. -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
