Doc Type: Bug Fix
Doc Text:
Prior to this update, running the "hg copy -A" command did not add broken symbolic links to a repository. The underlying source code has been modified to use the os.patch.lexists() method. As a result, "hg copy -A" adds the broken symbolic links as expected.

Description Dave Johansen 2013-09-10 12:07:39 EDT
Description of problem:
Broken symbolic links are not added like they should be when "copy -A" is used.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
mkdir dir
touch dir/file.txt
cd dir
ln -s file.txt link_valid.txt
ln -s nothing.txt link_invalid.txt
cd ..
hg init
hg add dir
hg ci -m "Initial checkin"
mv dir moved
hg copy -A dir/file.txt moved/file.txt
hg copy -A dir/link_valid.txt moved/link_valid.txt
hg remove dir/file.txt
hg remove dir/link_valid.txt
hg copy -A dir/link_invalid.txt moved/link_invalid.txt
hg remove dir/link_invalid.txt
hg stat

Actual results:
moved/link_invalid.txt is not added to the repository.

Expected results:
moved/link_invalid.txt should be added to the repository.

I noticed that version 1.4.3 of Mercurial is available, so I tested to see if the issue was fixed in that version, but it is not.

Also, potentially worth noting is that I did the above test on RHEL 5 (which uses Mercurial 1.3.1) and the same issue exists there as well.

Source rpm of Mercurial 1.4.3 with patch to fix the broken symbolic link issue

The fix that this patch is taken from can be found at:

I also noticed that Mercurial 1.4.3 is available, so I tested this patch applied to that updated source and it resolves the issue.
Comment 4 RHEL Product and Program Management 2013-10-13 19:11:05 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Comment 5 Dave Johansen 2013-10-25 00:26:32 EDT
This is still an issue and I'd like to request that it be considered that the fix be included in the next release.
