Show local port repository example source with nosync

[mtn88]

I believe it would make sense to change the example for the local port repository to prevent the source from syncing during 'port sync'

[raimue]

Can you elaborate a bit more why we would want to add the nosync flag? When the directory at the file:// URL is not a subversion working copy or git working tree, port sync should do nothing. Does the example cause any problems for you like this?

[jmroot]

It does run portindex but that's almost always desirable.

[mtn88]

Yes, the provided example causes a problem for me. And yes, I do have git enabled for my local repository. When I specify a local file:// URL I get the following error when running port sync:

--->  Updating the ports tree
port sync failed: Synchronization of 1 source failed

Appending [nosync] to my local repository URL fixes the problem.

I quote from the inline documentation in the file ${prefix}/etc/macports/sources.conf

To prevent a source from synchronizing when `port sync` is used,
append "[nosync]" at the end.

  Example: file:///Users/landonf/misc/MacPorts/ports [nosync]

And yes, portindex runs fine with our without [nosync] :-)

[raimue]

That error probably happens because your local git repository does not have a remote? Can you confirm with port -d sync that this is the problem? Then I would say the correct fix would be in macports-base to run the git pull --rebase command only if a remote is configured.

With nosync, the command port sync will not automatically run portindex on the ports tree. That means you always have to do that manually.

Thanks for the feedback!

I can confirm that my local repository doesn't have a remote. Here's the output from port -d sync (when [nosync] is not activated):
