Codesigning fails when binaries are in the `Resources` directory. This
change moves updater and ensures HQLauncher can handle the updater at
both paths.
The Launcher can download an error page rather than the full Launcher.
When this happens, the error page file is passed directly to unzip,
which promptly fails with the following message:
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of NewHQLauncher.zip or
NewHQLauncher.zip.zip, and cannot find NewHQLauncher.zip.ZIP, period.
This change improves the error message by checking the size of the
Launcher download and failing if the Launcher is smaller than the
smallest Launcher we've released. The smallest Launcher we've had is
308KB, so I picked 250KB as the limit because it's a nice rounder number
below that.
Before this change the update helper app in the Mac version of HQ
Launcher silently ignored errors. This change adds error handling to aid
troubleshooting.
I was mistaken when I added the EphemeralSession to stop local caching.
Using an EphermeralSession doesn't stop Foundation from caching a
request. Setting a request cache policy controls caching.
Before this change, the mac HQ launcher didn't set a User-Agent string.
This change adds a User-Agent header – HQLauncher/$version – to each
HTTP request the mac launcher makes.
The approach I took was to add the User-Agent header to each HTTP
request. There is room for improvement. Most of the session
initialization could be rolled up into a helper class that sets the
User-Agent headers and other configuration parameters. Making that
change would be too much overhead for this quick task.
