BrianH 28-Sep-2009 [18299] | Just a tweak of the dialect. The implementation is good. |
Carl 28-Sep-2009 [18300x2] | Pekr, R3 ports are totally multiplexed. |
The R3 model is far superior to R2. | |
Pekr 28-Sep-2009 [18302] | Carl - protocols/networking is the stuff community can work on. I suggest you concentrate on low-level stuff: - finish parse changes - back to Extensions and closer to Host interface, prepare for release and first porting efforts - please let's at least outline, what the concurrency model is going to be. Without it, Doc will not waste his time trying to port Cheyenne to R3, if R3 concurrency model is not at least defined? |
Carl 28-Sep-2009 [18303x2] | So, the question would be: what higher level models, such as Uniserve, can be implemented on top of R3 model? |
I've already stated the R3 concurrency model. But, it may have been lost in the web. | |
Pekr 28-Sep-2009 [18305x2] | OK, so let's forget the higher level models right now - there can be many over time :-) But multiplexing is one aproach, whereas combining it with concurrency is the other thing. So far Cheyenne spawns processes. We want R3 to be distributed computing king, no? :-) |
ah, yes, task! using threads one? | |
BrianH 28-Sep-2009 [18307] | So: task! is a thread, undefined sharing model, undefined intertask comm model. That's what we have so far. |
Pekr 28-Sep-2009 [18308] | http://ulf.wiger.net/weblog/2008/02/06/what-is-erlang-style-concurrency/ |
Carl 28-Sep-2009 [18309] | Correct: the model is: threaded CPU, shared memory, shared symbol space, shared system function space, separate evaluation stacks, separate user contexts. |
BrianH 28-Sep-2009 [18310] | Synchronization? |
Carl 28-Sep-2009 [18311x4] | Intertask comm is via Ports. |
Sync is via ports. | |
BTW, "ports" does not need to mean "sockets" | |
The host level can provide a more direct mechanism for inter-task sync and comm. | |
BrianH 28-Sep-2009 [18315] | Locking? With shared memory, mods could trounce each other. |
Steeve 28-Sep-2009 [18316] | Carl, about parse, is that a pain (in the ass) to have access (read-only) to the rule stack while parsing ? |
BrianH 28-Sep-2009 [18317] | Wow, sounds interesting. Why would you need that? |
Carl 28-Sep-2009 [18318] | I'm not a fan of locking, but sometimes it's necessary. Otherwise, mods can be "cloned" for multi-task uniqueness. |
Steeve 28-Sep-2009 [18319x2] | to know, if we can break the parsing in any place, and continue it later |
to have async parsing possible | |
BrianH 28-Sep-2009 [18321] | Copy-on-write? |
Carl 28-Sep-2009 [18322] | So, you want "parse continuations". |
Steeve 28-Sep-2009 [18323] | sort of... ::-) |
Pekr 28-Sep-2009 [18324] | streamed parsing? :-) |
BrianH 28-Sep-2009 [18325] | Incremental parsing. |
Carl 28-Sep-2009 [18326] | Yes, I understand. That would need to be 3.1. We do not want to delay 3.0. |
Steeve 28-Sep-2009 [18327] | sort of... :-) |
Carl 28-Sep-2009 [18328] | Anyway... Pekr.... I want to note one final thing. |
Pekr 28-Sep-2009 [18329] | listening :-) |
BrianH 28-Sep-2009 [18330] | I figured out how to do PARSE on seekable ports, so that might handle a lot of the problems. |
Carl 28-Sep-2009 [18331x2] | We need a way to make the "todo list" accessible and we need users to help us maintain it. |
An example is this... | |
Henrik 28-Sep-2009 [18333] | Carl, you mentioned a while ago that you urged us to work on the docs. Does this mean we can fill out the function reference with examples without them being overwritten? |
Carl 28-Sep-2009 [18334] | Maxim needs some changes for extensions... and has posted them somewhere, but I'm not sure where. |
Pekr 28-Sep-2009 [18335] | Chat ... it was about callbacks IIRC and some ideas ... |
Carl 28-Sep-2009 [18336] | Henrik, yes... please! Every edit is saved. |
BrianH 28-Sep-2009 [18337] | In R3 chat, plls a referenced web address. |
Pekr 28-Sep-2009 [18338] | #5045 in Chat ... |
Carl 28-Sep-2009 [18339x3] | But, we can also add locking to the docs... if we want. |
Pekr, for some things, I need more of a todo list rather than message thread. | |
I think it is ok to post it in CureCode, since that's easy to track. | |
BrianH 28-Sep-2009 [18342] | Speaking of which, add finishing the PROTECT changes to the list. All details in CureCode. |
Carl 28-Sep-2009 [18343] | Even if I've said, "don't post it there"... I now say, better there than nowhere. |
Pekr 28-Sep-2009 [18344] | so why just not to chat upon some areas and fill in already good project-plan? |
Carl 28-Sep-2009 [18345x2] | Pekr, yes good. |
So, when and where? | |
Pekr 28-Sep-2009 [18347x2] | Carl - R3 Chat is not nowhere, no? It was created to be a developer's tool too. But - we can make projects-plan.html a wiki page, so we can edit it and fill it with detail? |
