Method Details

setChangeMessage

public String setChangeMessage(ChangeUpdate update,
 String messageTemplate,
 String tag)

Sets messageTemplate and tag, that should be applied by the update.

The messageTemplate is persisted in storage and should not contain user identifiable information. See ChangeMessage.

Parameters:

update - update that sets messageTemplate.

messageTemplate - message in template form, that should be applied by the update.

tag - tag that should be applied by the update.

Returns:

message built from messageTemplate. Templates are replaced, so it might contain user identifiable information.

setChangeMessage

public String setChangeMessage(ChangeContext ctx,
 String messageTemplate,
 String tag)

See setChangeMessage(ChangeUpdate, String, String).

uploadedPatchSetTag

public static String uploadedPatchSetTag(boolean workInProgress)

byChange

public List<ChangeMessage> byChange(ChangeNotes notes)

Returns ChangeMessages from ChangeNotes, loads ChangeNotes from data storage (cache or NoteDB), if it was not loaded yet.

replaceChangeMessage

public void replaceChangeMessage(ChangeUpdate update,
 String targetMessageId,
 String newMessage)

Replace an existing change message with the provided new message.

The ID of a change message is different between NoteDb and ReviewDb. In NoteDb, it's the commit SHA-1, but in ReviewDb it was generated randomly. Taking the target message as an index rather than an ID allowed us to delete the message from both NoteDb and ReviewDb.

Parameters:

update - change update.

targetMessageId - the id of the target change message.

newMessage - the new message which is going to replace the old.

isAutogenerated

public static boolean isAutogenerated(String tag)

Determines whether the tag starts with the autogenerated prefix

Parameters:

tag - value of a tag, or null.

isAutogeneratedByGerrit

public static boolean isAutogeneratedByGerrit(String tag)

createChangeMessageInfo

public static ChangeMessageInfo createChangeMessageInfo(ChangeMessage message,
 AccountLoader accountLoader)

createChangeMessageInfoWithReplacedTemplates

public ChangeMessageInfo createChangeMessageInfoWithReplacedTemplates(ChangeMessage message,
 AccountLoader accountLoader)

ChangeMessage is served in template form to ChangeApi. Serve message with replaced templates to the legacy ChangeMessageApi endpoints. TODO(mariasavtchouk): remove this, after ChangeMessageApi is deprecated (gate with experiment).
