| 94 // ProfileSyncService is the layer between browser subsystems like bookmarks, | |
| 95 // and the sync backend. Each subsystem is logically thought of as being | |
| 96 // a sync datatype. | |
| 97 // | |
| 98 // Individual datatypes can, at any point, be in a variety of stages of being | |
| 99 // "enabled". Here are some specific terms for concepts used in this class: | |
| 100 // | |
| 101 // 'Registered' (feature suppression for a datatype) | |
| 102 // | |
| 103 // When a datatype is registered, the user has the option of syncing it. | |
| 104 // The sync opt-in UI will show only registered types; a checkbox should | |
| 105 // never be shown for an unregistered type, and nor should it ever be | |
| 106 // synced. | |
| 107 // | |
| 108 // A datatype is considered registered once RegisterDataTypeController | |
| 109 // has been called with that datatype's DataTypeController. | |
| 110 // | |
| 111 // 'Preferred' (user preferences and opt-out for a datatype) | |
| 112 // | |
| 113 // This means the user's opt-in or opt-out preference on a per-datatype | |
| 114 // basis. The sync service will try to make active exactly these types. | |
| 115 // If a user has opted out of syncing a particular datatype, it will | |
| 116 // be registered, but not preferred. | |
| 117 // | |
| 118 // This state is controlled by the ConfigurePreferredDataTypes and | |
| 119 // GetPreferredDataTypes. They are stored in the preferences system, | |
| 120 // and persist; though if a datatype is not registered, it cannot | |
| 121 // be a preferred datatype. | |
| 122 // | |
| 123 // 'Active' (run-time initialization of sync system for a datatype) | |
| 124 // | |
| 125 // An active datatype is a preferred datatype that is actively being | |
| 126 // synchronized: the syncer has been instructed to querying the server | |
| 127 // for this datatype, first-time merges have finished, and there is an | |
| 128 // actively installed ChangeProcessor that listens for changes to this | |
| 129 // datatype, propagating such changes into and out of the sync backend | |
| 130 // as necessary. | |
| 131 // | |
| 132 // When a datatype is in the process of becoming active, it may be | |
| 133 // in some intermediate state. Those finer-grained intermediate states | |
| 134 // are differentiated by the DataTypeController state. | |
| 135 // | |
| 136 // Sync Configuration: | |
| 137 // | |
| 138 // Sync configuration is accomplished via the following APIs: | |
| 139 // * OnUserChoseDatatypes(): Set the data types the user wants to sync. | |
| 140 // * SetDecryptionPassphrase(): Attempt to decrypt the user's encrypted data | |
| 141 // using the passed passphrase. | |
| 142 // * SetEncryptionPassphrase(): Re-encrypt the user's data using the passed | |
| 143 // passphrase. | |
| 144 // | |
| 145 // Additionally, the current sync configuration can be fetched by calling | |
| 146 // * GetRegisteredDataTypes() | |
| 147 // * GetPreferredDataTypes() | |
| 148 // * GetActiveDataTypes() | |
| 149 // * IsUsingSecondaryPassphrase() | |
| 150 // * IsEncryptEverythingEnabled() | |
| 151 // * IsPassphraseRequired()/IsPassphraseRequiredForDecryption() | |
| 152 // | |
| 153 // The "sync everything" state cannot be read from ProfileSyncService, but | |
| 154 // is instead pulled from SyncPrefs.HasKeepEverythingSynced(). | |
| 155 // | |
| 156 // Initial sync setup: | |
| 157 // | |
| 158 // For privacy reasons, it is usually desirable to avoid syncing any data | |
| 159 // types until the user has finished setting up sync. There are two APIs | |
| 160 // that control the initial sync download: | |
| 161 // | |
| 162 // * SetSyncSetupCompleted() | |
| 163 // * SetSetupInProgress() | |
| 164 // | |
| 165 // SetSyncSetupCompleted() should be called once the user has finished setting | |
| 166 // up sync at least once on their account. SetSetupInProgress(true) should be | |
| 167 // called while the user is actively configuring their account, and then | |
| 168 // SetSetupInProgress(false) should be called when configuration is complete. | |
| 169 // When SetSyncSetupCompleted() == false, but SetSetupInProgress(true) has | |
| 170 // been called, then the sync engine knows not to download any user data. | |
| 171 // | |
| 172 // When initial sync is complete, the UI code should call | |
| 173 // SetSyncSetupCompleted() followed by SetSetupInProgress(false) - this will | |
| 174 // tell the sync engine that setup is completed and it can begin downloading | |
| 175 // data from the sync server. | |
