cURL and libcurl

Fresh CA Cert Bundle Anyone?

cURLThe popular ca extract service on the curl web site converts the Firefox ca certs into a PEM file suitable for use with curl, wget or anything else OpenSSL-based that likes PEM formatted CA cert bundles.

The main script was fixed yesterday as it was previously getting a nightly source code snapshot to get the “magic” file to convert from, but I noticed they stopped updating the nightly source snapshots a good while ago so the updates had stopped!

Now, the script only gets the actually needed certdata file and converts it, so now it downloads a lot less data in vain and it also thus runs much faster. Now the PEM files offered on that page are up-to-date with the most recent Firefox.

Distributed Builds on Every Commit

I’m not sure everyone out there has yet realized what a cool build system we’ve created in the Rockbox project!

We’re using Subversion for source code version control. We have a master server that detects whenever there has been a commit and it then starts one thread for each known build server, where each thread connects to the remote server, asks it to update to a specific rev number and then asks the server to build for a particular target.

When the build is done, the master copies the build log and in some cases also the final zip file (which is then offered for download to users). At the time of this writing, we have 67 different builds and we average on 15 build servers. The master adapts to the servers that respond and just ignores the ones that don’t.

This has the cool outcome that roughly 5 – 7 minutes after a commit, there are zip files offered on the site with the absolutely latest code for 27 different players! There’s also a huge table presented on the site with the results from all builds so that warnings and build errors can be worked on.

Of course the master then goes back to check for commits again and the whole thing starts all over again.

Just now, the build for the Olympus M:Robe 500 was modified to depend on a recent ARM tool chain patch so we need to get all build server admins to update their ARM compilers!

The build servers are of course “donated” to the cause by volunteers. It is a fairly easy way to help out the project, if you have the sufficient bandwidth and machine. You can help too!
