Cecil,

May ask you to gist a test case that your are using?

Thank you!

I found a pretty simple way to reproduce this. I created an HTTPS hello
world server and another process that produces hundreds of HTTPS get
requests/sec. In io.js I found the memory leaking exponentially but not in
node 0.10.33. Perhaps this could make it easier to test this issue? I'm not
a C++ guy but seems like a simple way to test the hypotheses?

Shoot, I accidentally deleted my comment. But sure, I can do that. I have been running the test for a few minutes and on node 0.10.33 memory climbs and then flattens out. io.js consumes multiple gigs after running for the same amount of time. I'll post the gist in a few.

You'll have to generate your own SSL Cert but this should pretty clearly.

@cworsley4 running it locally now, will report back here. @bnoordhuis do not let this stop you, though :) This commit is surely fixing some leak.

indutny · 2015-03-24T04:42:37Z

@cworsley4 just to make sure, what io.js version are you using?

cworsley4 · 2015-03-24T12:25:35Z

I just duplicated the issue in 1.4.2, 1.5.1, and 1.6.2.

indutny · 2015-03-24T19:40:47Z

Interesting, I see some leaks in a client code... Will check it in a bit.

cworsley4 · 2015-03-24T22:30:26Z

@indutny Leaks in the code I provided?

indutny · 2015-03-24T22:34:01Z

Not sure about containment yet, but I am able to confirm it with your test
case. Thank you!

I'm glad to hear it! Of course let us know what you find, or if I can provide anything else to the effort.

indutny · 2015-03-25T03:22:54Z

Update PR with a fix :) @cworsley4 thank you so much! You helped a lot.

@jasisk: this should fix your leak, guys ;)

@jasisk: at least I have lots of hope for this

jasisk · 2015-03-25T03:24:22Z

Haha. 👍 Deploying.

Always call `Done` on the WriteWrap, and ensure that `EncOut` will consume all data in clear_in_ and invoke queued callbacks. Fix: nodejs#1075

cworsley4 · 2015-03-25T15:02:48Z

Do you guys think this PR will make it into #1252?

bnoordhuis · 2015-03-25T15:54:00Z

s/maed/made/ and can you end the sentence with a dot?

Fixed, thanks.

Redeploying. 😀

The CI: appears to be blue.
