This commit refactors the freebsd networking to:
1. Use predictable network naming
2. Properly handle DHCP vs static networks on up and reload [GH-5852]
3. Perform all networking configuration in a single command to prevent
partial configuration.
This updates the guest capabilities to run in as few communicator
commands as possible. Additionally, it fixes a number of issues around
hostname and idempotency.
This patch was tested against:
- puphpet/debian75-x64
- debian/jessie64
- debian/wheezy64
with custom networking, custom hostname, and rsync shared folders.
This commit does a few things:
1. Make the hostname update idempotent with `grep -w`
2. Add the given hostname to `/etc/hosts` as recommended by the docs
3. Add missing tests
This commit updates the procedure for configuring arch networks to occur
in a single command. Previously, each network was configured
independently. If, for some reason, one of the networks destroyed the
SSH connection, the box would be irrecoverable. This commit does not
alleviate that behavior, but attempts to mitigate it by running all
network-related configuration commands in a single communicator (SSH)
session.
The new procedure looks like this:
1. Upload a temp file to /tmp/vagrant-network-id... for each interface
on the guest.
2. Compile a commands array (of bash) to execute after all network
configurations have been uploaded.
3. Concatenate all the commands together in a single communicator
session.
This was tested against `terrywant/archlinux` using the following Vagrantfile:
```ruby
Vagrant.configure(2) do |config|
config.vm.box = "terrywang/archlinux"
config.vm.hostname = "banana-ramama.example.com"
config.vm.network "private_network", type: "dhcp"
config.vm.network "private_network", ip: "33.33.33.10"
config.vm.provision "file", source: "Vagrantfile", destination: "/tmp/vf"
config.vm.provision "shell", inline: "echo hi"
end
```
This commit updates the procedure for changing the hostname on arch
guests to occur in a single command. Previously, setting the hostname
and adding the value of the hostname to the /etc/hosts file was done in
two different uploads. This reduces the cycle to a single upload, making
provisioning a bit faster.
Additionally, this changes the behavior of the /etc/hosts file to:
1. Not remove localhost as an alias of 127.0.0.1
2. Prepend our custom hostname before localhost
The resulting /etc/hosts file will look something like:
127.0.0.1 my-host.example.com my-host
127.0.0.1 localhost.mydomain localhost
Tested against `terrywang/archlinux` using the following Vagrantfile:
```ruby
Vagrant.configure(2) do |config|
config.vm.box = "terrywang/archlinux"
config.vm.hostname = "banana-ramama.example.com"
config.vm.network "private_network", type: "dhcp"
config.vm.network "private_network", ip: "33.33.33.10"
config.vm.provision "file", source: "Vagrantfile", destination: "/tmp/vf"
config.vm.provision "shell", inline: "echo hi"
end
```
This fixes a fairly large tempfile leak. Vagrant uses a template
renderer to write network configuration files locally to disk. Then,
that temporarily file is uploaded to the remote host and moved into
place. Since Vagrant is such a short-lived process, GC never came along
and cleaned up those tempfiles, resulting in many temporary files being
created through regular Vagrant usage.
The Util::Tempfile class uses a block to ensure the temporary file is
deleted when the block finishes. This API required small tweaks to the
usage, but provides more safety to ensure the files are deleted.
Removed dependency upon netdom which is not always available on all Windows versions. This implementation that uses PowerShell and WMI should work on all OS and PowerShell versions.
Fixed another issue where host renames would always happen when the hostname was longer than 15 characters. The COMPUTERNAME environment variable only returns the first 15 characters so we no longer use that to check the current host name.
Reboot the Windows guest after renaming the computer so changes take affect immediately before attempting to provision the box.
- Changed rename from wmic to netdom since netdom seems to work correctly in Windows 2008R2 and newer OSs.
- Fixed Windows guest error translations, the wrong namespace was specified in the yaml file.
Run remote rsync as root to guarantee that rsync can write to guestpath.
This obviates the need to chown the guestpath to the SSH user prior to
sync.
This brings a substantial speedup (2x on a moderately-sized shared
folder) and properly triggers filesystem notifications on only the files
changed by a given sync.
- Fixed typo in helper test
- Removed extraneous machine.config prefix from Windows guest config validation
- Added WinRM communicator unit tests
- Added Windows guest capability unit tests
