03:05:16  <indutny>hey people
03:07:47  <AvianFlu>sup indutny !
03:07:53  <indutny>howdy, man?
03:08:20  <AvianFlu>just got back to sf a little while ago
03:10:34  <indutny>oh, cool
03:10:42  <indutny>I'm at NYC now
03:10:51  <indutny>just came back from the restaraunt
03:11:14  <AvianFlu>nice
03:11:18  <AvianFlu>how are you liking the US?
03:11:48  <indutny>well, people are very friendly over here
03:12:02  <indutny>and personally I enjoyed PDX much more than NYC :)
03:12:23  <AvianFlu>NYC moves very fast
03:12:26  <AvianFlu>it can be very intense
03:12:34  <indutny>well, Moscow is fast too
03:12:40  <AvianFlu>and people can be kind of rude in NY too
03:12:42  <indutny>so that's not really a case
03:12:45  <AvianFlu>I like it, I'm from there :D
03:12:47  <AvianFlu>but it can be a lot
03:12:57  <indutny>hehe :)
03:13:04  <indutny>well, actually Moscow is much more crowded than NYC
03:13:26  <indutny>for example, trains in subways (in Moscow) are going every 1.5 minutes and are almost full of people
03:13:48  <indutny>on every station in center
03:13:55  <AvianFlu>that's a lot of volume
03:13:55  <indutny>which is about 15 stations (probably more)
03:14:00  <indutny>yeah
03:14:22  <indutny>well, the thing is that Moscow is much greener than NYC
03:14:29  <indutny>it's easier to breathe there
03:15:27  <indutny>here's is a density of people in moscow (according to wikipedia) 27,334.5 /sq mi
03:15:38  <indutny>nyc: 412/sq mi
03:16:35  <AvianFlu>yeah, nyc is pretty spread out, past manhattan
03:16:42  <indutny>indeed
03:16:45  <AvianFlu>that's insane, 27,000 per sq mi!
03:16:50  <indutny>yeah
03:16:59  <indutny>and all those people are living out of moscow
03:17:09  <AvianFlu>funny that it's greener in the more crowded place
03:17:10  <indutny>like in 1-2 hours of train
03:17:16  <indutny>yeah

13:19:56  <piscisaureus>bnoordhuis: yup
13:20:01  <piscisaureus>arrived this morning
13:20:03  <bnoordhuis>cool
13:20:07  <bnoordhuis>how's the jet lag?
13:20:38  <piscisaureus>umm, well I didn't technically have a jetlag
13:20:45  <piscisaureus>since there was no tz difference
13:20:56  <piscisaureus>however, sleeping on the plane: -1
13:21:01  <bnoordhuis>ah, right
13:21:05  <bnoordhuis>yeah, awful
13:21:05  <piscisaureus>babies: -5
13:21:12  <piscisaureus>especially when I went there
13:21:14  <bnoordhuis>fly first class, problem solved
13:21:30  <piscisaureus>had no sleep, departed at 10am because I wanted to sleep on the plane
13:22:06  <piscisaureus>3 crying babies within 2 seats reach and a adhd toddler next to me
13:22:12  <piscisaureus>srsly, shoot me
13:22:24  <bnoordhuis>hah, hell
13:26:27  <piscisaureus>bnoordhuis: https://github.com/joyent/node/issues/3319 <- who is to blame there?
13:27:17  <bnoordhuis>piscisaureus: don't know, i've never seen that myself
13:29:39  <piscisaureus>tcp zerowindows means that the reader is too slow right?
13:30:11  <bnoordhuis>well.. it means the window got scaled down to nothing for some reason
13:31:42  <bnoordhuis>piscisaureus: come to think of it, that other guy complains about it happening on linux
13:31:55  <bnoordhuis>but i have never ever seen that, i always thought it was a windows issue
13:31:58  <piscisaureus>yep, that's why I removed the windows label
13:35:34  <bnoordhuis>piscisaureus: i just checked the kernel source, i guess zero windows are (at least theoretically) possible
13:35:50  <bnoordhuis>but yes, it means data comes in faster than the receiver can process it
13:37:18  <piscisaureus>zero window is not strictly an error, but failure to receive data is :-)
13:37:48  <bnoordhuis>i don't think there's much we can about that save growing the receive buffer
13:38:26  <piscisaureus>I meant: the guy reporting the windows problem says his node does not seem to do anything
13:38:34  <piscisaureus>so it may be unrelated to the linux issue
13:38:49  <piscisaureus>maybe just the SWS backoff bug in windows
13:39:17  <bnoordhuis>ah right. so a windows issue after all :)
13:39:58  <piscisaureus>this happens also when running the tcp pump bench
13:40:01  <piscisaureus>in libuv
13:40:11  <bnoordhuis>oh? interesting
13:40:32  <piscisaureus>although the kb article says that it should only happen when sending more than 64k at once
13:40:37  <piscisaureus>I am not sure tcp pump does that

18:02:02  <piscisaureus>bnoordhuis: isaacs: I feel that this is incredibly painful to track. In node issue numbers are sometimes mentioned, but quite randomly
18:02:02  <isaacs>piscisaureus: it's nice sometimes when there's an issue that you know people are waiting for a fix for
18:02:07  <isaacs>piscisaureus: yes.
18:02:11  <piscisaureus>ok
18:02:19  <piscisaureus>In that case I am not going to do it :-)
18:02:33  <isaacs>piscisaureus: and since the changelog head is also the commit message for the release, i sometimes end up closing the wrong thing with it
18:02:54  <isaacs>NEW RULE! NO ISSUE NUMBERS IN CHANGELOGS
18:02:55  <LOUDBOT>BECAUSE ING AIN'T DOING SO WELL, IT TURNS OUT
18:03:18  <isaacs>let's just make the descriptions descriptive enough that users know when their issue is resolved.
18:03:26  <piscisaureus>git log --cherry --pretty="format:%w(79,0,2)* %s (%cN)%n" <-- magic :-p
18:03:40  <indutny>log should be good too
18:03:40  <isaacs>and also try to mention in the closing message that the fix will be in X.Y.Z version of whatever.
18:03:41  <indutny>yeah
18:04:06  <isaacs>piscisaureus: oohh... i did not know about %w(,,)
18:04:12  <isaacs>piscisaureus: that's very handy :)
18:04:16  <piscisaureus>yep
18:04:36  <piscisaureus>I am going to do this changelog commit-style. E.g. format the thing, then fire up an editor for manual tweaks
18:04:43  <indutny>yeah
18:04:48  <isaacs>though, i find that it's nice to have the sha's in my git log helper, so that i can look at the actual commit and tweak the wording for more casual users.
18:04:53  <piscisaureus>yeah
18:05:11  <piscisaureus>I am going to dump the full log beneath, prefixed with #'s

18:05:51  <isaacs>a lot of time there are multiple commits that need to be squashed into a single CL entry, but need to be separate commits in the history for reasons
18:05:59  <piscisaureus>yeah, I will do that
18:06:35  <isaacs>what's log --cherry?
18:06:54  <piscisaureus>isaacs: skip merges and commits that are introduced on 2 branches
18:07:09  <isaacs>oic
18:07:18  <isaacs>thanks. the man page was overly detailed.
18:07:20  <piscisaureus>er, so the "double commits" would be shown only once
18:09:33  <piscisaureus>Yeah %cN was not good, gotta use %aN

19:35:06  <bnoordhuis>back
19:35:18  <tjfontaine>good day good sir
19:35:25  <bnoordhuis>hello :)
19:35:40  <bnoordhuis>hey, there was actually a call?
19:35:52  <bnoordhuis>i kind of assumed everybody was too jetlagged
19:35:52  <TooTallNate>bnoordhuis: ya, just me and isaacs and bert
19:36:00  <TooTallNate>but we cut it short
19:46:34  <indutny>ok
19:46:36  <indutny>571 req/s
19:46:37  <indutny>vs
19:46:40  <indutny>400 req/s
19:46:41  <indutny>haha
19:47:16  <indutny>and vs 537 req/s
19:47:21  <indutny>with that openssl optimization
19:50:29  <indutny>bnoordhuis: yt?
19:50:37  <bnoordhuis>indutny: ih
19:51:03  <indutny>bnoordhuis: wanna review patch?
19:51:11  <bnoordhuis>what patch?
19:51:36  <indutny>bnoordhuis: this one https://github.com/indutny/node/commit/c5a49e1a983b2dd8f0c05af3d3484bee0267877d
19:51:54  <indutny>a reusable shared buffer for all tls server
19:51:57  <indutny>s/server/servers
19:52:15  <indutny>which is improving performance by 7%
19:52:17  <indutny>approximately
19:52:26  <indutny>btw, I'm still seeing a lot of malloc calls
19:52:29  <indutny>on profile
19:52:39  <indutny>while it has ben cut off by the factor of 2 after this patch
19:56:02  <bnoordhuis>indutny: what happens if you need x bytes and there are only y bytes left in the pool?
19:56:24  <indutny>bnoordhuis: well, it'll try reading as much as it can
19:56:27  <indutny>oh
19:56:42  <indutny>I see now
19:57:11  <indutny>interesting question, btw
19:57:55  <bnoordhuis>indutny: looks like it should work though, you'll just end up doing small SSL_read() reads
19:57:57  <indutny>we wasn't handling that in old code, btw
19:58:07  <indutny>bnoordhuis: well, small reads ain't always possible
19:58:27  <indutny>tls is using block ciphers, so if block is big - we need more memory to decipher it
19:58:44  <indutny>I suppose SSL_read should return some special error in that case
19:58:53  <indutny>or it may be just copying part of the block to the memory
19:59:01  <indutny>reading this now : http://www.openssl.org/docs/ssl/SSL_read.html
19:59:47  <indutny>ah, it'll just slice
19:59:52  <indutny>so we should not care about it
20:01:11  <bnoordhuis>github is kinda flaky today
20:01:20  <bnoordhuis>i commented on the commit but now the comment is gone
20:01:47  <indutny>well, I'm force pushing it
20:01:49  <indutny>but I seen it
20:01:58  <indutny>now there is an assertion
20:02:09  <indutny>bnoordhuis: https://github.com/indutny/node/commit/58c802b814ec3ef0843205affc65490f0c10f60a
20:02:22  <indutny>I'll run `make test` now
20:03:59  <indutny>oh, a typo
20:04:44  <indutny>hehe
20:04:52  <indutny>I'm going to push it if tests are passing
20:05:02  <bnoordhuis>yeah, lgtm
20:05:13  <indutny>ok
20:05:29  <bnoordhuis>oh wait
20:05:36  <indutny>btw, I think we're going to visit Amsterdam this year
20:05:46  <indutny>prepare!! :)
20:05:49  <indutny>bnoordhuis: sup?
20:05:54  <bnoordhuis>hah, looking forward to it
20:06:03  <bnoordhuis>indutny: commented
20:06:28  <indutny>bnoordhuis: well, this may be stored in this module as a local variable
20:06:35  <indutny>bnoordhuis: yeah, I think there're no reason
20:07:26  <indutny>bnoordhuis: no more objections?
20:07:34  <indutny>tests are passing
20:07:36  <bnoordhuis>indutny: none apart from that one
20:07:41  <indutny>I only see a few EMFILEs
20:07:48  <indutny>https://github.com/indutny/node/commit/58c802b814ec3ef0843205affc65490f0c10f60a

20:09:21  <indutny>woot
20:13:38  <indutny>so, now I want to trace calls to malloc somehow
20:13:42  <bnoordhuis>node -e 'require("http").get("http://nodejs.org/").pipe(process.stdout)' <- why doesn't that actually print anything?
20:13:44  <indutny>callgrind isn't really helpful
20:13:51  <bnoordhuis>indutny: use massif
20:13:54  <indutny>massif ?
20:13:55  <indutny>ok
20:13:56  <indutny>will do
20:13:59  <indutny>time to eat now
20:13:59  <indutny>ttyl
20:14:05  <bnoordhuis>bon appetite
20:15:32  <TooTallNate>bnoordhuis: that is strange
20:16:08  <bnoordhuis>it is, isn't it?
20:16:15  <bnoordhuis>node -e 'var req = require("http").request("http://nodejs.org/"); req.pipe(process.stdout); req.end()' <- doesn't work either
20:17:51  <bnoordhuis>at least it's not a regression - it doesn't work with v0.6 either :)
20:18:06  <bnoordhuis>(that's with {method:"GET", ...})
20:18:11  <bnoordhuis>i'll open an issue
20:22:40  <piscisaureus_>bnoordhuis: that's because http.request doesn't take an url
20:22:51  <bnoordhuis>piscisaureus_: does too
20:22:54  <piscisaureus_>bnoordhuis: nor does get
20:22:57  <bnoordhuis>does too
20:23:08  <bnoordhuis>but it doesn't work with an options object either
20:23:38  <TooTallNate>node -e 'var req = require("http").request({ url: "http://nodejs.org", method: "get" }); req.pipe(process.stdout);'
20:23:40  <TooTallNate>nope
20:23:53  <bnoordhuis>TooTallNate: needs a req.end()
20:24:06  <bnoordhuis>but then it still doesn't work
20:24:35  <bnoordhuis>https://github.com/joyent/node/issues/3645
20:25:00  <piscisaureus_>bnoordhuis
20:25:04  <bnoordhuis>piscisaureus_: btw, when you trace it with strace -e read,epoll_wait you can see that it actually downloads
20:25:05  <piscisaureus_>require('http').get('http://nodejs.org', function(res) { res.pipe(process.stdout) })
20:25:16  <piscisaureus_>bnoordhuis: the request object is a writable stream
20:25:22  <piscisaureus_>the response object emits data events
20:25:25  <bnoordhuis>aww, damn

20:27:18  * perezdquit (Client Quit)
20:27:34  * perezdjoined
20:27:40  <bnoordhuis>why doesn't node complain though? req isn't or shouldn't be writable
20:27:50  * AndreasMadsenjoined
20:28:38  <piscisaureus_>bnoordhuis: s/writable/readable
20:28:47  <piscisaureus_>bnoordhuis: because there is no check :-)
20:28:53  <bnoordhuis>yeah, that's what i meant
20:28:57  <bnoordhuis>and indeed there is not
20:29:03  <bnoordhuis>maybe something for the streams refactor
20:29:06  <piscisaureus_>bnoordhuis: attaching event handlers is always possible
20:29:18  <piscisaureus_>bnoordhuis: the question is why a write only stream has a pipe method :-)
20:29:24  <TooTallNate>and there's only a Stream class, not a WritableStream or ReadableStream base class
20:29:49  <TooTallNate>but then that would cause problems for duplex streams :p
20:30:20  <bnoordhuis>streams have .readable and .writable properties though
20:30:44  <bnoordhuis>but perhaps it's not nice to throw when .readable isn't set yet when you call .pipe()
20:31:11  <bnoordhuis>i know the perfect solution!
20:31:22  <bnoordhuis>i'm going to open an issue, assign to isaacs and let him figure it out :)

21:17:12  * AlbireoXquit (Read error: Connection reset by peer)
21:18:52  <isaacs>TooTallNate: it'd be trivial to have a ReadableStream base clas, and another for WritableStream, and then a DuplexStream that just plucks the proto methods from both
21:19:46  <TooTallNate>isaacs: ya, but that wouldn't truly inherit from the two base classes. i.e. if you add a function to the prototype of one
21:19:57  <isaacs>no, of course not
21:20:02  <isaacs>it'd just inherit from Stream
21:20:19  <TooTallNate>i don't think that's a terrible solution
21:20:27  <isaacs>really, having to check for (and set) .writable and .readable is a huge pain in teh ass.
21:20:34  <isaacs>i mess that up every single time
21:20:42  <TooTallNate>in fact, i proposed it a long time ago on the mailing list ;)
21:20:45  <TooTallNate>isaacs: agree'd
21:21:16  <isaacs>the presence of the "write" method should indicate that it's writable, and the presence of pause/resume/pipe should indicate that its readable
21:21:48  <isaacs>also, ryah just pointed me to this: http://api.dartlang.org/io/InputStream.html
21:21:55  <isaacs>it's kind of an interesting API.
21:22:06  <isaacs>emits 'data' before it actually does the read()
21:22:16  <isaacs>then, at that point, you call read() which gives you whatever's available

21:45:49  <indutny>bnoordhuis: oh, openssl does a lot of allocation
21:45:58  <indutny>and other is some node's js internals
21:46:10  <indutny>which are just jit code addresses in massif's stack

21:46:21  <indutny>bbiab
21:54:26  <bnoordhuis>https://github.com/joyent/node/issues/3418 <- Wrong handling CJK symbols on navigation
21:54:33  <bnoordhuis>anyone have ideas on how that could happen?
21:55:35  <TooTallNate>bnoordhuis: is there maybe like a "unicode mode" we have to have the tty enter somehow?
21:55:46  <TooTallNate>perhaps an ansi escape sequence
21:56:08  <TooTallNate>that would make the terminal "know" that the unicode symbol is 1 char not 2 or 3 or whatever
21:56:09  <bnoordhuis>i'm thinking along similar lines
21:56:20  <TooTallNate>someone check bash!
21:56:22  <bnoordhuis>but i don't know what ansi code that should be :)
21:57:53  <bnoordhuis>it's odd that when you type or paste the character, it works
21:59:24  <bnoordhuis>maybe it's a terminal bug
21:59:43  <bnoordhuis>TooTallNate: what happens if you run `cat`, paste 错, then hit backspace?
22:00:14  <TooTallNate>bnoordhuis: the char gets deleted, but the cursor is at position 1 instead of 0
22:00:22  <TooTallNate>and backspace again does nothing
22:00:22  <bnoordhuis>yeah, same here
22:00:33  <TooTallNate>very strange
22:00:33  <bnoordhuis>actually, in my terminal the characters gets half-deleted
22:00:46  <TooTallNate>even stranger :D
22:00:58  <bnoordhuis>yeah. :-) it's deleted from the buffer but it's still half visible

22:07:41  <TooTallNate>bnoordhuis: it seems like bash itself though does things right

22:09:20  <bnoordhuis>TooTallNate: `rlwrap cat` does the right thing too
22:09:35  <bnoordhuis>guess i'll have to dig through the libreadline source

22:12:20  <TooTallNate>libreadline is a beast :(
22:17:17  <isaacs>careful reading libreadline
22:17:48  <isaacs>the gpl, it's infectious. all terminal parsing code you write might get infected.
22:18:20  <bnoordhuis>i'll read the source, describe my findings and you guys can write the patch :)
22:20:32  * chobi_echanged nick to chobi_e_
22:21:04  <bnoordhuis>another strange thing is that for example ć and â get rendered just fine
22:23:26  <indutny>haha
22:23:43  <indutny>isn't readline bsd?
22:33:58  <indutny>bnoordhuis: well, I've just added logging to Buffer::Replace
22:34:04  <indutny>and it seems that it isn't allocating a lot
22:35:04  <indutny>looks like v8 statistical analyzer is wrong here
22:42:54  <isaacs>indutny: i think you're thinking of editline
22:43:10  <isaacs>which was written specifically because readline is religious
22:44:12  <indutny>by other religious people
22:44:14  <indutny>:D
22:44:33  <indutny>isaacs: so, you want candor to be more like simplified javascript
22:44:40  <indutny>and be compatible with current javascript spec?
22:44:49  <indutny>like type coercion
22:44:53  <indutny>and function keyword
22:45:25  <isaacs>indutny: nono
22:45:45  <isaacs>indutny: i want a different language that can be used to write candor and other javascript-family languages to try out things
22:46:01  <isaacs>indutny: if, goto, and macros. no other flow control.
22:46:09  <indutny>oh
22:46:12  <isaacs>then we can experiment with new types of function syntaxes even
22:46:23  <isaacs>there are some other lowlevel things you sort of need, though
22:46:30  <isaacs>+-/*, numbers, strings, etc.
22:46:31  <indutny>like assembly, but with black-jack and bitches
22:46:45  <indutny>this is a great idea, actually
22:46:47  <isaacs>indutny: in fact, forget about the assembly!
22:46:54  <indutny>yeah
22:46:55  <isaacs>indutny: i don't know how feasible it is
22:47:05  <indutny>well, I think you can use JVM for this :)
22:47:18  <isaacs>indutny: i mean, candor and js ARE pretty different even at a low level
22:47:40  <isaacs>"asdf".length
22:47:41  <isaacs>etc.
22:48:21  <isaacs>but if you can define operators c++ style, you can define a . macro that can come after certain specific sorts of primitives
22:48:45  <isaacs>like how in scala you can define +!@#$ as an infix function that does whatever.
22:48:53  * paddybyersjoined
22:49:42  <indutny>yeah, I see now
22:49:54  <indutny>interesting idea, really
22:50:07  <isaacs>macro . { if (typeof(LEFT) === "string") ... }
22:50:10  <indutny>but I think what you're talking about is a low-level front-end to JVM
22:50:18  <isaacs>yeah, probably
22:50:28  <isaacs>i'll probably just keep using javascript forever honestly.
22:50:30  <indutny>because it's instructions are essentially providing the same stuff
22:50:34  <indutny>haha
22:51:13  <isaacs>but i was thinking during your talk, how you were saying that "while" is the only loop, because "for" is too complicated... isn't "while" pretty complicated?
22:51:20  <isaacs>i mean, it's an if AND a goto
22:51:24  <isaacs>that's two things!
22:52:11  <isaacs>and like, lisps sort of are intended to be a language for writing languages, but they always just end up writing more lisp.
22:52:23  <isaacs>clojure dsls always just look like clojure
22:53:05  * sh1mmerquit (Read error: Operation timed out)
22:54:09  * loladiroquit (Quit: loladiro)
22:55:05  <indutny>haha
22:55:29  <indutny>well, for is just a sugar for while
22:55:42  <indutny>and goto/label is so basic'ish
22:55:43  * sh1mmerjoined
22:56:07  <indutny>loops are actually more essential for a compiler design
22:56:51  <isaacs>indutny: while is just sugar for loop
22:57:01  <isaacs>loop { blah blah blah ... ; break; }
22:57:13  <indutny>hahaha
22:57:14  <indutny>indeed
22:57:35  <isaacs>indutny: but you can design it so that goto can only go to a labelled line within the macro.
22:57:35  <indutny>but if that was clear, compiler is operating with HIR(CFG - Control flow graph)
22:57:45  <isaacs>right
22:57:54  <isaacs>yeah, candor wants to actually be fast :)
22:57:55  <indutny>and this graph may contain loops
22:57:59  <indutny>yeeah
22:58:15  <isaacs>this javascripty macro playland language would be more about experimentation than speed.
22:58:20  <indutny>and loops have to be processed with some special algorithms to work properly
22:58:34  <indutny>well, if it's just an experiment - you can transcompile it to js
22:58:55  <isaacs>yeah, but at that point, why not just glue macros into js and make the monster all the way?
22:59:23  <indutny>hahahahaha
23:01:09  <indutny>oh, it's such a hell in NYC now
23:01:14  <indutny>I'm just going to melt
23:05:39  * piscisaureus_joined
23:11:23  <indutny>so, after all those patches
23:11:29  <indutny>node is quite good at TLS termination
23:11:40  <indutny>with cluster it works at 1035 req/sec on my MBP 15''
23:12:08  <indutny>and 756 req/sec without
23:12:17  <indutny>that's a way faster than nginx
23:12:20  <indutny>like 10x times :D
23:13:59  <indutny>bnoordhuis: and I think it's like a hard limit for it
23:14:37  <indutny>it's spending almost all other time in optimized (or without assembly version) openssl's code
23:15:03  <piscisaureus_>indutny: so why is it only 1.5x faster with cluster?
23:15:08  <piscisaureus_>indutny: should be like 8x right?
23:15:16  <piscisaureus_>:-p
23:15:17  <piscisaureus_>ok, 4x
23:15:20  <indutny>hm
23:15:26  <indutny>it shouldn't :)
23:15:31  <indutny>openssl is using multiple cores
23:15:44  <indutny>it's using one core only on handshake phase
23:16:10  <piscisaureus_>indutny: so openssl already offloads computation to other threads in node?
23:16:24  <indutny>yeah, I think so
23:16:36  <indutny>it's internals are using this somehow
23:16:40  <indutny>AFAIK
23:16:46  <indutny>better ask bnoordhuis about that ;)
23:16:55  <indutny>piscisaureus_: anyway it's expected because I've only two real cores
23:17:13  <indutny>but response time has been decreased too!
23:17:21  <indutny>from 130ms to 100ms
23:17:27  <indutny>I think this is very good improvement
23:17:52  <indutny>is there anyone who can test it in production?
23:17:58  <piscisaureus_>indutny: I think so too. I am just curious how low we can go :-)
23:18:00  <piscisaureus_>https://github.com/joyent/node/issues/868#issuecomment-1017139
23:18:14  <piscisaureus_>like, the theoretical upper limit
23:18:14  <indutny>3000 req/sec
23:18:18  <indutny>what can is she using?
23:18:30  <indutny>ah
23:18:32  <indutny>that's http
23:18:45  <indutny>or no?
23:18:58  <piscisaureus_>I dunno
23:19:01  <piscisaureus_>but I think so
23:19:06  <indutny>ah, she's somehow triggering ssl cache
23:19:09  <piscisaureus_>since he is serving a statuc file :-)
23:19:12  <indutny>odd, because 'ab' isn't doing it
23:19:37  <indutny>and also keep-alive :)
23:20:00  <indutny>how is it affecting benchmarking?
23:20:25  <indutny>I think node can do much more than 530 req/sec if ssl sessions will be reused
23:23:45  <indutny>piscisaureus_: was it 0.4 version?
23:23:51  <indutny>piscisaureus_: here https://github.com/joyent/node/issues/868#issuecomment-1017139
23:23:54  <piscisaureus_>indutny: you are the russian evil genious, I am just nudging you and trying to improve my understanding a little in the meantime :-)
23:24:04  <piscisaureus_>indutny: yeah, long time ago
23:24:08  <indutny>hahahaha
23:24:28  <indutny>piscisaureus_: that's actually pretty simple
23:24:32  <indutny>I just eat a dog on it
23:24:37  <indutny>like we're saying in Russia
23:24:45  <indutny>haha :D
23:24:51  <indutny>pquerna still knows much more than I am
23:25:32  * paddybyersquit (Quit: paddybyers)
23:26:05  <piscisaureus_>indutny: https://github.com/joyent/node/issues/2846#issuecomment-6627885 <-- so node x86 was much worse than x64. This must be the build fix you wrote at nodeconf
23:26:16  <indutny>yes, indeed
23:26:20  <piscisaureus_>the asm stuff
23:26:22  <piscisaureus_>yeah
23:26:25  <indutny>ah
23:26:26  <indutny>not
23:26:33  <indutny>this is not
23:26:50  <indutny>well, it's really not
23:27:01  <piscisaureus_>oh
23:27:02  <indutny>may be he was using shared version of openssl with inlined assembly?
23:27:11  <piscisaureus_>on windows?
23:27:13  <indutny>because I pushed the fix only two days ago
23:27:15  <piscisaureus_>seems unlikely
23:27:21  <indutny>piscisaureus_: yeah, for me too
23:27:27  <piscisaureus_>indutny: yeah so here's what I think
23:27:34  <indutny>piscisaureus_: but it's using different code for x86 and x64
23:27:40  <piscisaureus_>indutny: I knoiw
23:27:53  <indutny>kk, I'm listening, sorry
23:28:05  <piscisaureus_>indutny: but for heavy math x64 code is quite a bit more efficient than x32 code
23:28:17  <indutny>indeed, especially for cryptography
23:28:45  <piscisaureus_>ah well nvm. He should try the x86 version again and see if that is now fast too
23:29:20  <piscisaureus_>Are there nodejitsu guys staying in amsterdam?
23:29:33  <indutny>em... x86 version should be as slow as it was
23:29:46  <indutny>it may be affected only by the SlabBuffer fix that I pushed today
23:29:52  <piscisaureus_>ok
23:29:53  <piscisaureus_>right
23:29:59  <indutny>so it's like 7% improvement
23:30:15  <indutny>when inlined assembly is in use
23:30:19  <piscisaureus_>Actually, lemme try for a change, instead of trusting your numbers :-)
23:30:22  <indutny>should be much less without it
23:30:39  <indutny>piscisaureus_: yeah, you're the only windows guy I know over here
23:30:40  <indutny>btw
23:30:48  <indutny>I forgot to ask you on nodeconf
23:30:52  <indutny>piscisaureus_: why windows?
23:30:53  <indutny>:D
23:31:09  <indutny>that's really what I'm often thinking about
23:31:10  <piscisaureus_>Don't ask. It pays the bills.
23:31:33  <indutny>ah, job security
23:31:51  <indutny>ok, next question
23:32:15  <indutny>openssl is spending ~5 % of our runtime while clearing memory buffers
23:32:21  <indutny>this is good for security
23:32:26  <indutny>but don't really good for performance
23:32:30  <indutny>as they're doing it manually
23:32:36  <indutny>because literally:
23:32:57  <indutny> *) New function OPENSSL_cleanse(), which is used to cleanse a section of
23:32:57  <indutny> memory from it's contents. This is done with a counter that will
23:32:57  <indutny> place alternating values in each byte. This can be used to solve
23:32:57  <indutny> two issues: 1) the removal of calls to memset() by highly optimizing
23:32:57  <indutny> compilers, and 2) cleansing with other values than 0, since those can
23:32:58  <indutny> be read through on certain media, for example a swap space on disk.

23:33:52  <piscisaureus_>hmm
23:34:29  <indutny>yeah
23:34:35  <indutny>that's what I said too
23:36:47  * dapquit (Quit: Leaving.)
23:36:59  <piscisaureus_>bnoordhuis broke the windows build in f78ce087ba195540c8293
23:37:32  <piscisaureus_>that means he has to buy all the drinks tomorrow.
23:41:05  <indutny>where is he, btw?
23:41:16  <piscisaureus_>I don't know
23:41:24  <piscisaureus_>At home I suppose
23:43:10  <indutny>oh, ain't you living together?
23:43:29  <piscisaureus_>hahahah
23:43:42  <piscisaureus_>did you think that?
23:44:29  <indutny>nope, just kidding :P
23:44:33  <indutny>s/kidding/trolling
23:44:36  <piscisaureus_>hmm
23:44:39  <indutny>learned a lot from you
23:44:43  <indutny>hahaha :D
23:44:51  <indutny>no offense, really
23:44:55  <piscisaureus_>this asm stuff is not working on windows
23:45:14  <piscisaureus_>indutny: please try and troll me.
23:45:20  <indutny>piscisaureus_: really?
23:45:31  <indutny>piscisaureus_: (about asm)
23:45:37  <piscisaureus_>indutny: well, it's complicated :-)
23:45:53  <piscisaureus_>indutny: there's a lot of asm in the openssl tree but I can't compile with it
23:45:59  <indutny>yeah
23:46:03  <piscisaureus_>indutny: but I will try to figure that out tomorrow
23:46:07  <piscisaureus_>apparently you need perl for that
23:46:08  <indutny>and it's really complicated
23:46:13  <piscisaureus_>I will probably try to gypify it
23:46:17  <indutny>piscisaureus_: I thought about the following pattern
23:46:40  <indutny>we can just precompile them and put into .S with ifdefs for each platform
23:47:04  <indutny>and then use those files in gyp and define some platform flag for them
23:47:24  <piscisaureus_>it has all these perl files
23:47:26  <piscisaureus_>why
23:47:57  <indutny>well, it's retarded, that's it
23:48:14  <indutny>but one the other side - you can just go and write a new one
23:48:16  <indutny>;)
23:50:39  <piscisaureus_>it has all these perl scripts that generate asm code
23:50:48  <indutny>obviously
23:51:06  <piscisaureus_>can we not do that with v8's builtin assembler :-p
23:51:06  <indutny>piscisaureus_: and they even wrote an asm generator in perl for them
23:51:24  <indutny>we can, but if openssl guys will change any file - we will be completely borked
23:51:42  <indutny>because we'll need to port their changes
23:52:02  <piscisaureus_>hmm
23:52:05  <piscisaureus_>I have to think about this
23:52:10  <piscisaureus_>let me try to sleep again
23:52:11  <piscisaureus_>:-)
23:54:21  <indutny>ook
23:54:25  <indutny>sleep tight, bertje
23:55:52  <piscisaureus_>ghe lol
23:58:01  <isaacs>indutny: i can test your ssl changes in production, yes. but voxer can probably test them much better.
23:58:07  <isaacs>that is, in a better production
23:58:14  * c4milojoined
23:58:36  <indutny>isaacs: yeah, I just asked mjr on twitter
23:58:43  <isaacs>oh, great!
23:58:48  <indutny>isaacs: but your testing would be great too
23:58:50  <indutny>MOAR TESTING
23:58:50  <LOUDBOT>YOU COULD HAVE HAD MORE
23:59:33  <indutny>first one patch should be working fine, if it builds
23:59:48  <indutny>but SlabBuffer patch contains a js code changes in very important parts of tls
