Make workflow show output json usable for replay #110

feedmeapples · 2023-02-11T07:04:41Z

What was changed

Made workflow show --output json produce replayable history

Why?

Allows exporting replayable history with syntax

workflow show --output json -w workflow_id > ~/history.json

Checklist

Closes
How was this tested:

E2E test here #171

Any docs updates needed?

nit: why aren't we using multiline strings here for better readability?

I'll change in a new PR

workflow/workflow_commands.go

-	var lastEvent historypb.HistoryEvent // used for print result of this run
+	var lastEvent historypb.HistoryEvent


Why remove the comment?

if lastEvent usage changes later in code then the comment needs to be updated as well. Figured it's better to give a good name to the variable than commenting it (i think the name is already good, or another option executionResult )

changed to wfResult, should clarify the variable better and not need the comment?

workflow/workflow_commands.go

-		hIter := sdkClient.GetWorkflowHistory(tcCtx, wid, rid, watch, enumspb.HISTORY_EVENT_FILTER_TYPE_ALL_EVENT)
-		iter := &historyIterator{iter: hIter, maxFieldLength: maxFieldLength, lastEvent: &lastEvent}
-		err = output.PrintIterator(c, iter, po)
+		iter := sdkClient.GetWorkflowHistory(tcCtx, wid, rid, watch, enumspb.HISTORY_EVENT_FILTER_TYPE_ALL_EVENT)


Watch and JSON aren't compatible, can we ensure they're not both set?

workflow/workflow_commands.go

+	history := &historypb.History{}
+	history.Events = events
+
+	common.PrettyPrintJSONObject(history)


Just verifying that this will not generate pretty output when stdout is not a TTY.

This requires tests.

I mostly want to see a test for this but otherwise LGTM.

I mostly want to see a test for this but otherwise LGTM.

added a test here #171 separately as it requires temporaltest to exist in the server repo (and to not block the current PR). One more #170

I’d rather use the cli for the test server so we utilize it as much as possible

I’d rather use the cli for the test server so we utilize it as much as possible

i'm split between these options:

Ideally i would like integration tests to directly cover CLI dev server, the commands and options. To test one thing at a time instead of implicitly proxy testing CLI server in unrelated tests. I see your point though

update: changing to SDK based dev server

common/util.go

 	if err != nil {
-		fmt.Printf("Error when try to print pretty: %v", err)
-		fmt.Println(o)
+		fmt.Fprintf(w, "Error when try to print pretty: %v", err)


All fmt.Printf should be fmt.Fprintf. No?

yes! i'll send separately to not mix
