</span>Our database contains exactly what the portindex2postgres.tcl script<br>
produces (note the different naming). You can just generate the data<br>
locally by running it against PortIndex.<br>
<br>
You need to have the ports tree in a directory named "ports", then run<br>
the following command from the parent directory:<br>
<br>
port-tclsh /path/to/macports-infra/jobs/<wbr>portindex2postgres.tcl<br>
<br>
This will create a PortIndex.sql in the current directory. Ignore or<br>
remove the macports.conf and sources.conf files that are also created.<br>

<br>
</span>Yes, the idea would be that macports-webapp is updated after every commit.<br>
<br>
To achieve that, you could use a job in buildbot, but then the result<br>
needs to be transferred to the macports-webapp. Alternatively, you could<br>
deliver a WebHook from GitHub to do this within macports-webapp. It<br>
largely depends on what kind of data you want to gather and how.<br>

<br>
</span>I did not argue against working on a separate branch. I just wanted to<br>
point out that pull request reviews on GitHub might pose a problem as<br>
they cannot depend on each other. It is up to you and your mentors to<br>
work out the details.<br>

<br>
</span>The PortIndex file itself is generated with the 'portindex' command,<br>
which only updates the data for Portfiles that have a modification time<br>
that is newer than the existing PortIndex file.<br>
<br>
The portindex2postgres.sql script merely converts the PortIndex file<br>
from the custom format based on Tcl lists to SQL. The output will always<br>
contain SQL statements with the full data for every port.<br>
