Enable Direct Download for systemVM templates by shwstppr · Pull Request #3731 · apache/cloudstack

shwstppr · 2019-12-02T09:00:45Z

Description

As of now provisioning of System VMs with direct download enabled template was not supported. Even after setting such templates as SYSTEM template, while provisioning SSVM and CPVM the server would return an error message like,

System vm template is not ready at data center 1, wait until it is ready to launch secondary storage vm

This behaviour has been changed and it allows the server to provision SSVM and CPVM even with direct download system templates.
Additionally, changes have been made to make different timeouts for direct download functionality configurable using global settings. Following global configurations have been added for this,
direct.download.connect.timeout - Connection establishment timeout in milliseconds for direct download
direct.download.socket.timeout - Socket timeout (SO_TIMEOUT) in milliseconds for direct download
direct.download.connection.request.timeout - Requesting a connection from connection manager timeout in milliseconds for direct download

Types of changes

Breaking change (fix or feature that would cause existing functionality to change)
New feature (non-breaking change which adds functionality)
Bug fix (non-breaking change which fixes an issue)
Enhancement (improves an existing feature and functionality)
Cleanup (Code refactoring and cleanup, that may add test cases)

Screenshots (if appropriate):

New global settings,

-    public HttpDirectDownloadCommand(String url, Long templateId, PrimaryDataStoreTO destPool, String checksum, Map<String, String> headers) {
+    public HttpDirectDownloadCommand(String url, Long templateId, PrimaryDataStoreTO destPool, String checksum, Map<String, String> headers, int connectTimeout, int soTimeout) {
        super(url, templateId, destPool, checksum, headers);
+        setConnectTimeout(connectTimeout);


Can these be set on the DrectDownloadCommand constructor?

+            try {
+                connectTimeout = Integer.parseInt(configDao.getValue(DirectDownloadConnectTimeout.key()));


Please do not use this and use the config key value() method, same below

nvazquez · 2019-12-23T13:16:15Z


    private void updateDirectDownloadTemplate(long templateId, long zoneId) {
-        TemplateDataStoreVO templateStore = _tmplStoreDao.findByTemplateZone(templateId, zoneId, DataStoreRole.Image);
+        TemplateDataStoreVO templateStore = _tmplStoreDao.findByTemplate(templateId, DataStoreRole.Image);


So we are updating every reference in every zone for the template?

@nvazquez as we do not store store_id in cloud.template_store_ref table for direct download template, we cannot find the entry in the table for a zone while update. Continued with same behaviour from user direct download templates. Do we need to change this for system direct download templates? updateDirectDownloadTemplate is new method added in this PR only

                }

+                // delete template refs for this zone
+                templateZoneDao.deleteByZoneId(zoneId);


@DaanHoogland please review if this is the correct place to cleanup template_zone_ref entries for a zone to be removed? Or should this call be made after the successful removal of DataCenterVO in success block below? Functionality-wise it is working fine.
cc @rhtyd

@shwstppr absolutely only on success. I don't think the zone is still usable if deletion of the zoneVO, but it is not right to do an automatic clean-up of items (templates) in a container (zone) if the container is not disposed of.
