102 // ProfileSyncService is the layer between browser subsystems like bookmarks, | |
103 // and the sync backend. Each subsystem is logically thought of as being | |
104 // a sync datatype. | |
105 // | |
106 // Individual datatypes can, at any point, be in a variety of stages of being | |
107 // "enabled". Here are some specific terms for concepts used in this class: | |
108 // | |
109 // 'Registered' (feature suppression for a datatype) | |
110 // | |
111 // When a datatype is registered, the user has the option of syncing it. | |
112 // The sync opt-in UI will show only registered types; a checkbox should | |
113 // never be shown for an unregistered type, and nor should it ever be | |
114 // synced. | |
115 // | |
116 // A datatype is considered registered once RegisterDataTypeController | |
117 // has been called with that datatype's DataTypeController. | |
118 // | |
119 // 'Preferred' (user preferences and opt-out for a datatype) | |
120 // | |
121 // This means the user's opt-in or opt-out preference on a per-datatype | |
122 // basis. The sync service will try to make active exactly these types. | |
123 // If a user has opted out of syncing a particular datatype, it will | |
124 // be registered, but not preferred. | |
125 // | |
126 // This state is controlled by the ConfigurePreferredDataTypes and | |
127 // GetPreferredDataTypes. They are stored in the preferences system, | |
128 // and persist; though if a datatype is not registered, it cannot | |
129 // be a preferred datatype. | |
130 // | |
131 // 'Active' (run-time initialization of sync system for a datatype) | |
132 // | |
133 // An active datatype is a preferred datatype that is actively being | |
134 // synchronized: the syncer has been instructed to querying the server | |
135 // for this datatype, first-time merges have finished, and there is an | |
136 // actively installed ChangeProcessor that listens for changes to this | |
137 // datatype, propagating such changes into and out of the sync backend | |
138 // as necessary. | |
139 // | |
140 // When a datatype is in the process of becoming active, it may be | |
141 // in some intermediate state. Those finer-grained intermediate states | |
142 // are differentiated by the DataTypeController state. | |
143 // | |
144 // Sync Configuration: | |
145 // | |
146 // Sync configuration is accomplished via the following APIs: | |
147 // * OnUserChoseDatatypes(): Set the data types the user wants to sync. | |
148 // * SetDecryptionPassphrase(): Attempt to decrypt the user's encrypted data | |
149 // using the passed passphrase. | |
150 // * SetEncryptionPassphrase(): Re-encrypt the user's data using the passed | |
151 // passphrase. | |
152 // | |
153 // Additionally, the current sync configuration can be fetched by calling | |
154 // * GetRegisteredDataTypes() | |
155 // * GetPreferredDataTypes() | |
156 // * GetActiveDataTypes() | |
157 // * IsUsingSecondaryPassphrase() | |
158 // * IsEncryptEverythingEnabled() | |
159 // * IsPassphraseRequired()/IsPassphraseRequiredForDecryption() | |
160 // | |
161 // The "sync everything" state cannot be read from ProfileSyncService, but | |
162 // is instead pulled from SyncPrefs.HasKeepEverythingSynced(). | |
163 // | |
164 // Initial sync setup: | |
165 // | |
166 // For privacy reasons, it is usually desirable to avoid syncing any data | |
167 // types until the user has finished setting up sync. There are two APIs | |
168 // that control the initial sync download: | |
169 // | |
170 // * SetFirstSetupComplete() | |
171 // * GetSetupInProgressHandle() | |
172 // | |
173 // SetFirstSetupComplete() should be called once the user has finished setting | |
174 // up sync at least once on their account. GetSetupInProgressHandle() should | |
175 // be called while the user is actively configuring their account. The handle | |
176 // should be deleted once configuration is complete. | |
177 // | |
178 // Once first setup has completed and there are no outstanding | |
179 // setup-in-progress handles, CanConfigureDataTypes() will return true and | |
180 // datatype configuration can begin. | |
