kog / js-tda Goto Github PK

So that people always have the ability to run latest.

I originally wrote JS-TDA to accommodate them, but took it out as I didn't see a need to do so. Still, might be handy rather than forcing people to open a new tab. You can drop a log with multiple dumps in it, which will (hopefully) display properly in the meantime.

Thoughts:

• Add a DIV under the dumps with a drag/drop area, a la 'no dumps' UI
• Maybe just add a plus button/DIV with a "append logs" or somesuch
• Should probably fingerprint each dump with a combination of file + time occurred to prevent collisions

Didn't have any of these in the thread dumps I was using to test, but just ran across an example. I should add this, as it is quite handy.

You know... this has been bothering me for a while, I just keep forgetting to fix it. Maybe I should stop being lazy, and fix it...

In addition to the summary of things like thread counts, sleeping threads etc., TDA shows a bunch of advice on the "dump node", the tree node corresponding to the highest level of the dump. This includes suggestions like:

• N% of your threads are sleeping, this might be resource contention or lots of waiting threads
• Warnings about monitors without locking threads

It would be worth seeing how hard this is to add

That points to the GitHub pages hosted version... No need to make people suffer through a saga to use the tool.

If you have two dumps, each with 230 threads in them (just happened to do this today), you'll get both dumps listed in the UI and can switch between them. This works fine, and seems to do what you'd expect, except that the "thread index" counter is shared between both of the dumps.

When you click on the first dump you see threads 0-229, but when you click the second dump you see threads 230-459. This is a little confusing, especially since there's nothing that works cross-dump (IE: you can't click something in Dump 0 that goes to Dump 1).

This is hopefully a simple counter issue, and would involve resetting the counter between parsing dumps.
