This is unfortunately a case where the best documentation is the javascript code tiddler itself (not that intuitive, but start reading the core “shadow” tiddlers for the things you are interested in).
If we go to Sidebar> More> Shadow Tiddlers> $:/core/modules/syncer.js
, we can see a bunch of tiddler titles that control config settings.
/*\
title: $:/core/modules/syncer.js
type: application/javascript
module-type: global
The syncer tracks changes to the store and synchronises them to a remote data store represented as a "sync adaptor"
\*/
(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
/*
Defaults
*/
Syncer.prototype.titleIsLoggedIn = "$:/status/IsLoggedIn";
Syncer.prototype.titleIsAnonymous = "$:/status/IsAnonymous";
Syncer.prototype.titleIsReadOnly = "$:/status/IsReadOnly";
Syncer.prototype.titleUserName = "$:/status/UserName";
Syncer.prototype.titleSyncFilter = "$:/config/SyncFilter";
Syncer.prototype.titleSyncPollingInterval = "$:/config/SyncPollingInterval";
Syncer.prototype.titleSyncDisableLazyLoading = "$:/config/SyncDisableLazyLoading";
Syncer.prototype.titleSavedNotification = "$:/language/Notifications/Save/Done";
Syncer.prototype.titleSyncThrottleInterval = "$:/config/SyncThrottleInterval";
Syncer.prototype.taskTimerInterval = 1 * 1000; // Interval for sync timer
Syncer.prototype.throttleInterval = 1 * 1000; // Defer saving tiddlers if they've changed in the last 1s...
Syncer.prototype.errorRetryInterval = 5 * 1000; // Interval to retry after an error
Syncer.prototype.fallbackInterval = 10 * 1000; // Unless the task is older than 10s
Syncer.prototype.pollTimerInterval = 60 * 1000; // Interval for polling for changes from the adaptor
/*
Instantiate the syncer with the following options:
syncadaptor: reference to syncadaptor to be used
wiki: wiki to be synced
*/
function Syncer(options) {
var self = this;
this.wiki = options.wiki;
// Save parameters
this.syncadaptor = options.syncadaptor;
this.disableUI = !!options.disableUI;
this.titleIsLoggedIn = options.titleIsLoggedIn || this.titleIsLoggedIn;
this.titleUserName = options.titleUserName || this.titleUserName;
this.titleSyncFilter = options.titleSyncFilter || this.titleSyncFilter;
this.titleSavedNotification = options.titleSavedNotification || this.titleSavedNotification;
this.taskTimerInterval = options.taskTimerInterval || this.taskTimerInterval;
this.throttleInterval = options.throttleInterval || parseInt(this.wiki.getTiddlerText(this.titleSyncThrottleInterval,""),10) || this.throttleInterval;
this.errorRetryInterval = options.errorRetryInterval || this.errorRetryInterval;
this.fallbackInterval = options.fallbackInterval || this.fallbackInterval;
this.pollTimerInterval = options.pollTimerInterval || parseInt(this.wiki.getTiddlerText(this.titleSyncPollingInterval,""),10) || this.pollTimerInterval;
this.logging = "logging" in options ? options.logging : true;
// Make a logger
The important ones being:
Syncer.prototype.titleSyncThrottleInterval = “$:/config/SyncThrottleInterval”;
Syncer.prototype.taskTimerInterval = 1 * 1000; // Interval for sync timer
…
this.throttleInterval = options.throttleInterval || parseInt(this.wiki.getTiddlerText(this.titleSyncThrottleInterval,""),10) || this.throttleInterval;
this.errorRetryInterval = options.errorRetryInterval || this.errorRetryInterval;
These are miliseconds, so the tiddler value sould be as well.
So, to change it, we set the text field of $:/config/SyncThrottleInterval
to say 30000
for once every 30 seconds. This affects both browser → server, AND server → filesystem syncing.
