*grml* - still no luck using those API's. And I truly running out of ideas
:(
Do you have any idea what's going wrong here?
The sad news are, the deletion of the remote documents doesn't seem to have
any effect at all :(
I've got the following databaseRestoreBackup func:
func databaseRestoreBackup(database: CBLDatabase, from date: NSDate,
withManager databaseManager: CBLManager) throws -> CBLDatabase?{
...
//delete the old database
try databaseDelete(database, withManager: databaseManager)
//Unzip backup to the manager directory
SSZipArchive.unzipFileAtPath(sourcePath, toDestination:
databaseManager.directory)
//create new revisions of the restored documents
let database = try databaseManager.databaseNamed(database.name)
let enumerator = try database.createAllDocumentsQuery().run()
for i in 0..<enumerator.count{
if let doc = enumerator.rowAtIndex(i).document {
try doc.newRevision().save()
}
}
//purge all remote documents
try PersistenceManager.sharedInstance().purgeRemoteDocuments(channel:
Identity.sharedInstance().tenant, completion: { (result: AnyObject?) ->
Void in
do{
try self.databaseStartReplication(database, completion: { (notification) ->
Void in
PersistenceManager.sharedInstance().databaseSetup(database, withManager:
databaseManager)
})
} catch let error as NSError{
NSLog(error.localizedDescription)
}
})
...
}
Which calls the following purgeRemoteDocuments func (Is there a better way
reading only the docs of the given channel?):
func purgeRemoteDocuments(channel channel: String, completion:
CompletionHandler? = nil) throws{
guard let serverURL = self.replicationConfig["url"] as? NSURL,
let serverDatabase = self.replicationConfig["database"] as? String,
let serverUsername = self.replicationConfig["username"] as? String,
let serverPassword = self.replicationConfig["password"] as? String
else { throw PersistenceManagerError.ConfigInvalid }
Alamofire.request(.GET,
serverURL
.URLByAppendingPathComponent(serverDatabase)
.URLByAppendingPathComponent("_all_docs"),
parameters:[ "channels":"true" ])
.authenticate(user: serverUsername, password: serverPassword)
.responseJSON { response in switch response.result {
case .Success(let data):
let json = JSON(data)
if let documents = json["rows"].array{
for document in documents{
if let channels = document["value"]["channels"].arrayObject as? [String]{
if channels.indexOf(channel) != nil{
if let docID = document["id"].string{
Alamofire.request(.DELETE,
serverURL
.URLByAppendingPathComponent(serverDatabase)
.URLByAppendingPathComponent(docID))
.authenticate(user: serverUsername, password: serverPassword)
.responseJSON { response in switch response.result {
case .Success(_):
NSLog("Deleted remote document with id '\(docID)'")
case .Failure(let error):
NSLog(error.localizedDescription)
}
}
}
}
}
}
}
if let handler = completion{
handler(result: data)
}
case .Failure(let error):
NSLog(error.localizedDescription)
if let handler = completion{
handler(result: error)
}
}
}
}
