Change subject: core: add canDoAction to remove storage connection
......................................................................
Patch Set 4: I would prefer that you didn't submit this
(16 inline comments)
See comments inline.
A few general clarifications:
1. Several of my comments are personal style comments - feel free to implement
or ignore as you see fit.
2. Something seems to be off with your formatter. In the project's style, we
add spaces around brackets.
E.g.: "if(someCondition){" should be changed to "if (someCondition) {".
This repeats throughout the patch.
3. The comments on
backend/manager/modules/dal/src/main/resources/bundles/AppErrors.properties
apply to ALL the AppErrors files as well.

IMHO, this can be done with an annotation on the connection object - no need to
repeat this code in all the commands
Line 37: }
Line 38: StorageServerConnections connection =
getStorageServerConnectionDao().get(connectionId);
Line 39: StorageType storageType = connection.getstorage_type();
Line 40: if(storageType.isFileDomain()) {
Line 34: List<StorageDomain> domains = new ArrayList<>();
Line 35: if(StringUtils.isEmpty(connectionId) ) {
Line 36: return
failCanDoAction(VdcBllMessages.ACTION_TYPE_FAILED_STORAGE_CONNECTION_ID_EMPTY);
Line 37: }
Line 38: StorageServerConnections connection =
getStorageServerConnectionDao().get(connectionId);
Why do I need this as well as getParameters().getConnection()?
If the connection object on the parameters cannot be trusted, perhaps it should
be refactored to just have a connection ID?
Line 39: StorageType storageType = connection.getstorage_type();
Line 40: if(storageType.isFileDomain()) {
Line 41: //go to storage domain static, get all storage domains
where storage field = storage connection id
Line 42: domains = getStorageDomainsByConnId(connectionId);
Line 46: }
Line 47: }
Line 48: else if(storageType.equals(StorageType.ISCSI)) {
Line 49: List<String> domainNames = new ArrayList<>();
Line 50: List<String> diskNames = new ArrayList<>();
Java 7!
yey!
(Although IMHO a LinkedList would be more appropriate here)
Line 51: //go to luns to storage connections map table, get it from
there
Line 52: List<LUNs> luns =
getLunDao().getAllForStorageServerConnection(connectionId);
Line 53: if(luns.size() > 0) {
Line 54: String volumeGroupId = null;
Line 49: List<String> domainNames = new ArrayList<>();
Line 50: List<String> diskNames = new ArrayList<>();
Line 51: //go to luns to storage connections map table, get it from
there
Line 52: List<LUNs> luns =
getLunDao().getAllForStorageServerConnection(connectionId);
Line 53: if(luns.size() > 0) {
I'd use if (!luns.isEmpty())
Line 54: String volumeGroupId = null;
Line 55: for(LUNs lun : luns) {
Line 56: volumeGroupId = lun.getvolume_group_id();
Line 57: if(StringUtils.isNotEmpty(volumeGroupId)) {
Line 53: if(luns.size() > 0) {
Line 54: String volumeGroupId = null;
Line 55: for(LUNs lun : luns) {
Line 56: volumeGroupId = lun.getvolume_group_id();
Line 57: if(StringUtils.isNotEmpty(volumeGroupId)) {
I think a positively phrased condition will be easier to understand
Line 58: // non empty vg id indicates there's a storage
domain using the lun
Line 59: String domainName = lun.getStorageDomainName();
Line 60: domainNames.add(domainName);
Line 61: }
Line 65: diskNames.add(lunDiskName);
Line 66: }
Line 67: }
Line 68: String domainNamesForMessage = null;
Line 69: if(domainNames.size() > 0 ) {
I'd use !domainNames.isEmpty()
Line 70: // Build domain names list to display in the error
Line 71: domainNamesForMessage =
prepareEntityNamesForMessage(domainNames);
Line 72: if(diskNames.size() < 1) {
Line 73: return
prepareFailureMessageForDomains(domainNamesForMessage) ;
Line 68: String domainNamesForMessage = null;

Line 70: // Build domain names list to display in the error
Line 71: domainNamesForMessage =
prepareEntityNamesForMessage(domainNames);
Line 72: if(diskNames.size() < 1) {
I'd use diskNames.isEmpty()
Line 73: return
prepareFailureMessageForDomains(domainNamesForMessage) ;
Line 74: }

Line 72: if(diskNames.size() < 1) {
Line 73: return
prepareFailureMessageForDomains(domainNamesForMessage) ;
Line 74: }
Line 75: else {
I'd unwrap this
Line 76: String diskNamesForMessage =
prepareEntityNamesForMessage(diskNames);
Line 77: return
prepareFailureMessageForDomainsAndDisks(domainNamesForMessage,diskNamesForMessage);
Line 78: }
Line 79: }

prepareEntityNamesForMessage(diskNames);
Line 77: return
prepareFailureMessageForDomainsAndDisks(domainNamesForMessage,diskNamesForMessage);
Line 78: }
Line 79: }
Line 80: else if(diskNames.size() > 0 ) {
I'd use !diskNames.isEmpty()
Line 81: String diskNamesForMessage =
prepareEntityNamesForMessage(diskNames);
Line 82: return
prepareFailureMessageForDisks(diskNamesForMessage);
Line 83: }
Line 84:
Line 99: domainNamesForMessage.append(",");
Line 100: }
Line 101: // Remove the last "," after the last domain
Line 102:
domainNamesForMessage.deleteCharAt(domainNamesForMessage.length() - 1);
Line 103: return domainNamesForMessage.toString();
This entire function should be changed to a simple
StringUtils.join(entityNames, ",")
Line 104: }
Line 105:
Line 106: @Override
Line 107: protected void executeCommand() {
Line 132: protected Map<String, Pair<String, String>> getExclusiveLocks() {
Line 133: return
Collections.singletonMap(getConnection().getconnection(),
Line 134:
LockMessagesMatchUtil.makeLockingPair(LockingGroup.STORAGE_CONNECTION,
Line 135:
VdcBllMessages.ACTION_TYPE_FAILED_OBJECT_LOCKED));
Line 136: }
Please move this method either up or done, so all the CDA message related
methods are grouped together
Line 137:
Line 138: protected String
createDomainNamesListFromStorageDomains(List<StorageDomain> domains) {
Line 139: // Build domain names list to display in the error
