The following text is quoted from ChangeLog. I think it is strange a bit that the singleton method of the FrameInfo class returns a collection (array) of FrameInfo objects. And the name `caller()' is confusing with Kernel.caller(). Any good name? Or any comment of this new feature? BTW, I added second argument of Kernel::caller(). You can specify required array size with it. For example, caller(0, 1) returns only 1 frame (the current frame which calls caller() method) information string. # ... and performance is also improved. </pre> SASADA Koichi 2012-05-26T05:07:16 http://comments.gmane.org/gmane.comp.lang.ruby.core/44553 <pre> Issue #6499 has been reported by prijutme4ty (Ilya Vorontsov). ---------------------------------------- Feature #6499: Array::zip https://bugs.ruby-lang.org/issues/6499 Author: prijutme4ty (Ilya Vorontsov) Status: Open Priority: Normal Assignee: Category: Target version: Sometimes it's more natural to have Array::zip rather than Array#zip.

Client renegotiation is still considered a problem, even with secure renegotiation support. It's now possible to either completely disable client renegotiation at all or to specify a maximum number of handshakes. The feature is opt-in, the default is as it was before, to allow arbitrary client renegotiation attempts. The feature is meant to help in scenarios where the OpenSSL extension is used to run a server that should not support client renegotiation for security reasons. Because we don't support renegotiation in the OpenSSL extension, it wasn't possible to write explicit test cases, but I created a simple server script [1] that can be tested with tools such as OpenSSL's s_client [2]. For example, when running the server script at [1], testing the feature could be accomplished by: openssl s_client -connect localhost:8443 And then pressing 'R' and Enter, you should receive an error like this: RENEGOTIATING 140639302223680:error:1409E0E5:SSL routines:SSL3_WRITE_BYTES:ssl handshake failure:s3_pkt.c:591: If you don't, any feedback is much appreciated!

Is it possible to change ruby-interpeter in such a way that &amp;:proc could be at any place. matrix.pmap(&amp;:join,' ') is much prettier than matrix.join(' ',&amp;:join) What is the reason behind this restriction? And if one can remove this restriction, we'd have new nice syntax. 2) I'm not very experience in functional programming with curry etc, but it seems to me that currying proc without supplying first argument(self) can be common task when &amp;:meth syntax is in play.

The goal of this is to make it easier to handle Location, Refresh, meta-headers, and URIs in retrieved documents. (While the HTTP RFC specifies the Location must be an absolute URI, not every server follows the RFC.) In order to process redirect responses from bad servers or relative URIs in requested documents the user must create an object that contains both the requested URI and the response object to create absolute URIs. This patch reduces the amount of boilerplate they are required to write. Only the (({request_uri})) is used from the URI given when creating a request. The URI is stored internally and updated with the host, port and scheme used to make the request at request time. The URI is then copied to the response object for use by the user. To preserve backwards compatibility the new behavior is optional. This allows requests with invalid URI paths like (({Net::HTTP::Get.new '/f%'})) to continue to work. Users of string paths will not be able to retrieve the requested URI.
