Red Hat Bugzilla – Bug 243588
cp gives error when destination is symlink
Last modified: 2008-06-16 21:31:54 EDT
Description of problem:
Previous versions of cp would honour symlinks as the target of a copy.
coreutils-5.97-12.5.fc6 exhibits the usual, expected behavior. The version
released with F7 does not, giving an error message instead.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. cd /var
2. ln -sf beta tmp/alpha
3. echo "blah" > tmp/alpha (this creates a file called beta with "blah" in it)
4. rm tmp/beta
5. echo "blah" > file
6. cp file tmp/alpha
cp: cannot create regular file `tmp/alpha': File exists
[root@localhost var]# dir tmp
lrwxrwxrwx 1 root root 4 Jun 10 04:35 alpha -> beta
-rw-r--r-- 1 root root 5 Jun 10 04:36 beta
Regressing to coreutils-5.97-12.5.fc6 exhibits the correct behavior
Thanks for the report. That is indeed a bug. I've just fixed it upstream:
This fix seems to introduce some other problems, reading further in the thread.
I'm going to defer this bug-fix until F-8, or until a new stable coreutils
release appears with the fix.
As of Fedora 8, coreutils-6.9-9.fc8, cp still does not properly work with the
dangling symlink despite the upstream commentary suggesting that the fix had
been worked out an incorporated into their code.
When will this be brought down into Fedora ?
The existing patch upstream has subtle flaws, and is about to be removed.
I'll post a link here over the weekend.
Here's why GNU cp will (by default) continue to fail to copy through dangling
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.
Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008.
Fedora 7 is no longer maintained, which means that it will not
receive any further security or bug fix updates. As a result we
are closing this bug.
If you can reproduce this bug against a currently maintained version
of Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
