Pike 8.0.240 release candidate
by Peter Bortas 10 May '16

10 May '16

I did an effort to get a Windows 10 environment up this weekend, but it's not done. So here is a release candidate together with an old classically compiled Windows version. If no one finds anything bad (where bad is worse than the latest stable) this will be the release next weekend. Pike 8.0.240 beta/release candidate: https://pike.lysator.liu.se/pub/pike/beta/8.0.240/Pike-v8.0.240.tar.gz Other builds: https://pike.lysator.liu.se/pub/pike/beta/8.0.240/Pike-v8.0.240-win32-oldli… -- Peter Bortas

Promises and HTTP
by Pontus Östlund 06 May '16

06 May '16

Hi guys! I started experimenting with the new Concurrent.Promise/Concurrent.Future classes and implementing a HTTP client module using the promise/future stuff. The reason for this is that the async stuff in Protocols.HTTP.Query is far from intuitive. With promises/futures I think you get a super clean API that is easy to use. So I started experimenting with this and would like to have your thoughts on the matter. Right now I put it as Protocols.HTTP.Promise but any suggestions on what to call it and where to place it would be appreciated. Here’s some examples of how it would be used at the moment. // Fetch a single URL import Protocols.HTTP; int main() { string url1 = ”http://pike.lysator.liu.se <http://pike.lysator.liu.se/>”; Concurrent.Future q1 = Promise.get_url(url1); q1->on_success(lambda (Protocols.HTTP.Query ok) { werror(”Successfully got %O\n”, ok->host); })->on_failure(lambda (Protocols.HTTP.Query fail) { werror(”%O failed!\n”, fail->host); }); return -1; } // Fetch multiple URLs and call on_success in parallell for each request. import Protocols.HTTP; int main() { string url1 = ”http://pike.lysator.liu.se <http://pike.lysator.liu.se/>”; string url2 = ”http://roxen.com <http://roxen.com/>”; Concurrent.Future q1 = Promise.get_url(url1); Concurrent.Future q2 = Promise.get_url(url2); array(Concurrent.Future) all = ({ q1, q2 }); all->on_success(lambda (Protocols.HTTP.Query ok) { werror(”Successfully got %O\n”, ok->host); })->on_failure(lambda (Protocols.HTTP.Query fail) { werror(”%O failed!\n”, fail->host); }); return -1; } // Fetch multiple URLs and call on_success when all has succeeded. // on_failure will be called immediately if one request fails. import Protocols.HTTP; int main() { string url1 = ”http://pike.lysator.liu.se <http://pike.lysator.liu.se/>”; string url2 = ”http://roxen.com <http://roxen.com/>”; Concurrent.Future q1 = Promise.get_url(url1); Concurrent.Future q2 = Promise.get_url(url2); Concurrent.Future batch = Concurrent.results(({ q1, q2 })); all->on_success(lambda (array(Protocols.HTTP.Query) ok) { werror(”Successfully got %O\n”, ok->host); })->on_failure(lambda (Protocols.HTTP.Query fail) { werror(”%O failed!\n”, fail->host); }); return -1; } So, any thoughts on this?

CHANGES for next release
by Peter Bortas ＠ Pike developers forum 06 May '16

06 May '16

Should any of the following have a CHANGES note?: * ADT.Heap: Added low_peek(). * Fix GTK2.SourceBuffer undo/redo signal names * Fix spelling of composite[d]_changed signal - Is that an API change or where the signals not properly hooked up before? * Crypto/SSL - There is a ton of Crypto/SSL changes. I'm just going to trust Nilsson and/or Grubba to make sure relevant things are in CHANGES.

Wrong enum type
by Arne Goedeke 03 May '16

03 May '16

An enum with two elements can get the wrong resulting type: > enum A { a, b }; Compiler Warning: 2: a is private but not used anywhere. Compiler Warning: 2: b is private but not used anywhere. Compiler Warning: 2: A is private but not used anywhere. (1) Result: int(1..1) The problem seems to be in or_pike_types handling of T_ZERO, but I am unsure about how that should be fixed. Also, whats the point of those warnings about private unused definitions? Is that a hilfe issue? Arne
