This commit adds the spicy-proton gem to vmpooler.gemspec. Without this change the spicy-proton gem is in the Gemfile, but not the gemspec, causing issues when deploying from gem.
Prior to this commit hostnames for VMs provisioned by vmpooler were 15
random characters. This is difficult for humans to tell apart.
This commit updates the naming to use the `spicy-proton` gem to generate
adjective noun pair names for the VMs, which I think would be easier for
humans to tell apart, as well as fun and memorable to say.
The random name should not exceed 15 characters in order to prevent
issues with NETBIOS, etc as discussed in the attached ticket.
This commit updates the way that checkoutlock is defined so it is not passed through bin/vmpooler. Without this change there's an unnecessary layer the mutex passes through.
This commit adds a shared mutex to vmpooler API so that checkout requests can be synchronized across threads. Without this change it is possible in some scenarios for vmpooler to allocate the same SUT to different API requests for a VM.
The host['boottime'] variable in the function _check_ready_vm no longer
has its parent object in reference due to the refactoring in pull
request #269. So in order to get the same information without the
performance impact from duplicate object lookups, we get similar
information from the time that the VM is ready.
This commit updates the create_linked_clone pool option to correctly detect when linked clones have been set at a pool level. Without this change a pool setting create_linked_clone to false is not interpreted correctly, and a linked clone is created if possible.
This change adds the running host for a VM to the API data available via /vm/hostname. Without this change the running host would be logged to vmpooler log, but not available any other way. Additionally, the data will specify if a machine has been migrated. Without this change parent host data for a vmpooler machine is not available via the vmpooler API.
This commit adds a new configuration parameter to allow setting whether to create linked clones on a global, or per pool basis. Without this change vmpooler would always attempt to create linked clones. The default behavior of creating linked clones is preserved.
This allows the user to change the cluster in which the targeted pool
will clone to. Upon configuration change, the thread will wake up and
execute the change within 1 second.
This commit updates the reference to domain from vmpooler config. Without this change the domain value is read as an empty string and breaks checkouts.
This commit duplicates the vm_ready? check to the API layer to allow for API to validate that a VM is alive at checkout. Without this change API relies upon the checks in pool_manager validating pools. This change should allow for additional insight into whether a machine is in a ready state and resopnding at checkout time.
Before this change looping over many pools would query the redis backend
for each pool, leading in slow response from the backend for configurations
with many pools (60+)
Changed the requests to use redis pipelines https://redis.io/topics/pipelining
This is supported since the beginning, so will not force any redis update for
users. The pipeline method runs the queries in batches and we need to loop
over the result and reduces the number of requests to redis by N=number of
pools in the configuration.
Before this change we used the API /status endpoint to get specific information
on pools such as the number of ready VMs and the max.
This commit creates two new endpoints to get to that information much quicker
1) poolstat?pool= takes a comma separated list of pools to return, and will provide
the max, ready and alias values.
2) /totalrunning will calculate the total number of running VMs across all pools
