portgroup github: unexpected tarball_from behavior

[jasonliu-- (Jason Liu)]

I'm working on a new portfile, and I need to use the github.tarball_from option to retrieve the full tarball that includes all of the submodules. Here's what I have in my file:

PortGroup           github 1.0

github.setup        mumble-voip mumble 1.3.4
github.tarball_from releases

However, when I specify github.tarball_from releases in my portfile, MacPorts doesn't appear to be fetching the correct tarball. In theory, according to the PortGroup file, github.tarball_from releases should trigger the following URL to be set:

switch ${args} {
    ...
    releases {
        github.master_sites ${github.homepage}/releases/download/${git.branch}
    }
    ...
}

If you go to the ​releases page of the port that I'm working on, the URL on the file that I want fetched appears to be correct, i.e. the link for the file listed as "mumble-1.3.4.tar.gz" corresponds to: ​https://github.com/mumble-voip/mumble/releases/download/1.3.4/mumble-1.3.4.tar.gz. This file should be approximately 8.59 MB in size. However, the file that the MacPorts build system actually fetches corresponds to the ​Source code (tar.gz) file, which is only around 4.9 MB in size. Perhaps something is wrong with the handle_tarball_from proc?

Can't reproduce.

Is something wrong with the MacPorts on my machine, then? Has anyone else every complained about such a thing happening (i.e. MacPorts trying to fetch distfiles from the wrong location)?

[jasonliu-- (Jason Liu)]

Wait a minute, you know what? I'm an idiot. I forgot to delete the previously downloaded distfile from /opt/local/var/macports/distfiles after I added the github.tarball_from releases line, so MacPorts thought that it had already downloaded the distfile (which was the "Source code (tar.gz)" file, from before I added the tarball_from line). Deleting the old distfile forced MacPorts to download the tarball again, which this time was the one I was expecting.

You can close this ticket with a resolution of "problem with keyboard-to-chair interface".
