Hi marijn: I met a problem in my work, what i do:
Every client submit its version which get from websoket and its unconfirm steps, that means server version will high then the client version. at the same time, i save all others steps group by clientID.
Then there was a problem, i have no idea how to deal with the unconfirm steps with the others steps.
if (messageArray.length > 0) {
for (let i = 0; i < messageArray.length; i++) {
let tempTr: any = flag ? initTr : new Transform(newDoc);
if (clientID != messageArray[i].clientID) {
const over = messageArray[i].steps;
let rebaseResult = rebaseStepsHandle(unconfirm, over, tempTr, cursorCache.from, cursorCache.to);
unconfirm = rebaseResult.unconfirm;
newDoc = rebaseResult.doc;
cursorCache.from = rebaseResult.from;
cursorCache.to = rebaseResult.from;
flag = false;
} else {
unconfirm = unconfirm.slice(messageArray[i].steps.length);
}
}
unconfirm = unconfirm.map((v) => {
return v.step;
});
steps = unconfirm;
} else {
steps = unconfirm.map((v: any) => {
return v.step;
})
}
function rebaseStepsHandle(steps: any, over: Array<Step>, transform: any, from: number, to: number) {
for (let i = steps.length - 1; i >= 0; i--) transform.step(steps[i].inverted);
for (let i = 0; i < over.length; i++) {
if (over[i]) {
try {
transform.step(over[i]);
} catch (error) {
console.log(transform.doc.nodeSize);
throw error
}
}
}
let result = [];
let newFrom;
let newTo;
for (let i = 0, mapFrom = steps.length; i < steps.length; i++) {
let mapped = steps[i].step.map(transform.mapping.slice(mapFrom));
mapFrom--;
try {
if (mapped && !transform.maybeStep(mapped).failed) {
transform.mapping.setMirror(mapFrom, transform.steps.length - 1);
result.push({ inverted: mapped.invert(transform.docs[transform.docs.length - 1]), step: mapped });
}
} catch (error) {
//
}
}
I get this
RangeError: Position 2818 out of range
any suggest will be very helful
