It will make it a lot easier to manage the cache if we use the original
file names, which often include the file version. This also changes the
download process to be resumable if there is a partial file in the cache,
and switches from calling wget on the command line to using the python libs
'requests' and 'clint' to provide a similar experience. While its not so
important for this particular bit of code to use those libraries, I think
those two will allow us to provide a better user experience throughout the
whole of fdroidserver.
In this case, it is already doing special tricks fetching the file size
from the server before trying to download it. I suppose this code could
instead check if the file exists, and if so, check the hash sum. I think
that would be slower for most people since checking the hash on large files
takes a noticeable about of time, while a HTTP HEAD request is pretty tiny.
Install version 25 now. Also use the smaller tools zip. While at it,
also remove the tools re-install - it's not worth it, as long as we keep
the initial tools zip up to date.
Fixes a couple errors like:
File "./makebuildserver", line 30, in vagrant
out += line
TypeError: Can't convert 'bytes' object to str implicitly
If universal_newlines=False, the default, then Popen will return bytes if
the newlines in the data do not match the system's newlines. Setting it to
true enables auto-conversion, and then guarantees that the data is always
str.
"If universal_newlines is True, the file objects stdin, stdout and stderr
are opened as text streams in universal newlines mode, as described above
in Frequently Used Arguments, otherwise they are opened as binary streams."

makebuildserver: support running VirtualBox in a VM
For debian.jenkins.net, our test environment is a kvm instance that does not expose the hardware virtualization instructions. So this auto-detects whether the current machine, virtual or not, supports the hardware virtualization. If not, it uses VirtualBox's software emulator, which should run everywhere, even in a kvm instance.
See merge request !108
This checks the local CPU settings to see if it has the right virtualizing
CPU instructions, and only uses VirtualBox hardware virtualization on
setups where it is available. VMs instances usually do not provide these
instructions. Where the CPU features are not available, it will use VB's
software virtualization.
4 gigs is still a common amount of RAM these days for laptops, if the VM
takes almost all of that, it makes the machine drag to almost a halt. Most
apps build fine in 1gig of RAM, indeed that's the default for most CI
instances, like travis-ci and gitlab-ci.
On slow machines or VMs like the Debian jenkins box, the VM boot timeout
needs to be a lot longer, otherwise vagrant times out before setting up
the VM.
Setting it in the config file was not working, and right now, all of the
options are in the config file and not as command line flags, so remove
--debian-mirror to keep that consistent.
This also provides a config option to override that default. ~/.cache is
a standard location on GNU/Linux machines for cached content. It is also
good to have the cache outside of the git repo in case `git clean -fdx` is
run, which would delete all files in the directory that are not part of the
git repo, including buildserver/cache/
This makes it so that ./makebuildserver will run without any config file,
using the defaults that are embedded in the script itself. This is like
how `fdroid` works.
This host automatically detects which is the closest mirror, then uses that
one. It does so dynamically, so it'll work on machines that move too. Now
that we are pushing more people to run F-Droid build servers, the defaults
should take those use cases into account.
This keeps the numbers of names down to a minimum, and since the config
is placed right next to the script, this keeps tab completion working
nicely when the config file is in place.
The old file name is still supported.
On some setups, using a custom apt mirror is essential, so this adds a
command line flag to override the default one:
http://ftp.uk.debian.org/debian/
For example, someone who runs a local mirror for offline and low bandwidth
situations.
This uses a % rather than a .format() to avoid escaping { and }, which have
meaning when using .format().
config.vm.box_url can be a list/tuple of URLs, which is useful to specific
a locally cached copy. This is needed on slow connections, so that if it
fails, the download of jessie32.box does not have to start from the
beginning of the file again.
Add optional support for vagrant-cachier plugin
Building the basebox is excruciating for people on slow connections. I'm particularly sensitive to this after living in Central America for awhile :)
This won't affect anyone who hasn't installed the plugin. For those who do, it creates a persistent shared folder for each box (ie. testing23.box) and detects directories to cache between VM builds (apt, gems, pip, chef cache, etc.)
(The only downside is that, for those following server setup does who are not aware what vagrant-cachier does, it might be unexpected that artifacts persist between vagrant destroys.)
