GRPharoPlatform>>isIpAddress bug?

by Marco A. Gonzalez

Hi, I think I've discovered an problem in the following class>>method but still considering myself somewhat of a newbie, I'm not entirely sure: GRPharoPlatform>>isIpAddress: aString | ip | ip := aString findTokens: '.'. ^ ip size = 4 and: [ ip allSatisfy: [ :each | each greaseInteger notNil and: [ each greaseInteger notNil between: 0 and: 255] ] ] The problem is the last line "each greaseInteger notNil between: 0 and: 255"... where the notNil message returns a true or false, and it does not respond to "between:and:". I believe the fix ought to be to remove the "notNil" in the last line to result in the line: "each greaseInteger between: 0 and: 255" since the "notNil" is already considered before the "and:". This is from the most recent One-click download: Pharo1.3 Latest update: #13307 ------------------------------------------------------ Marco A. Gonzalez

According to this tracker entry: http://code.google.com/p/pharo/issues/detail?id=3527 Class Generator was added as 13009 very early in 1.3. Yet, in my 1.3 there is no class Generator... (nobody needed it, either...) I will re-open the report. -- Marcus Denker -- http://marcusdenker.de

I have found on StackOverflow that GNU and Squeak support Generators: http://stackoverflow.com/questions/6529815/how-are-coroutines-implemented-i… Could they be used with Pharo?

If you can use the plugin, maybe it's worth to use it :). I just followed Sven instructions from one of hist last emails :). Cheers, Guille

In the May thread it sounded like a project was getting kicked off to do something that might be official-ish. Has there been progress on this? Yes, there is a project called Zodiac that reimplements socketstream and adds secure (SSL) socket streams. These are then used for HTTPS. I think they should also work for sending email over SSL. At the moment Zodiac is still in development, if you are interested, see my messages to the Pharo dev list. Some people have used local tunneling (http -> https) using stunnel as a way around this problem. > Second question, while playing with mail in my pharo image, the entire image seems to block during the handshake/send.

My impression was that all Smalltalks did at one time, but that some (visualworks? squeak?) had fixed that years ago. Pharo typically blocks when the main or UI thread is doing something, which includes IO. You can perfectly do all kinds of things in other threads. Check the process monitor or try some multithreaded server. HTH, Sven

Status of SSL on Pharo? (and some general questions on mail and IO)

by Larry White

Hi, I'm looking for a way to send email using SSL. Googling I've found several conversations from earlier this year on the subject, including one thread from May and another from January. In the May thread it sounded like a project was getting kicked off to do something that might be official-ish. Has there been progress on this? Second question, while playing with mail in my pharo image, the entire image seems to block during the handshake/send. Is there a way around that? If not, would a solution perhaps be to run a separate image to send emails and communicate via a db or file system? Final question, does Pharo always block on IO? My impression was that all Smalltalks did at one time, but that some (visualworks? squeak?) had fixed that years ago. Thanks.
