[Pharo-project] String asPacked/fromPacked:

by Martin Dias

Hi I discovered this protocol in String hierarchy. Are you familiar with it? The method comment of #fromPacked: is: "Convert from a longinteger to a String of length 4." The only sender in Pharo 2.0 is MethodFinder. For WideString, it does not work. In examples: ByteString fromPacked: 'text' asPacked. ---> 'text' ByteString fromPacked: 'martin' asPacked. ---> 'rtin' WideString fromPacked: ('text' asWideString asPacked). ---> error WideString>>asPacked can be easily fixed adding an explicit return to the calculation (it's now implicitly returning self). But... it only encodes one letter: WideString fromPacked: 'martin' asWideString asPacked ---> 'n' I checked that in Squeak 4.3 there are not senders too. So... Should we fix the WideString implementation, or directly remove this protocol? Martin

I changed to to trigger on https://ci.inria.fr/pharo/job/Pharo-2.0/lastSuccessfulBuild/buildTimestamp so that a very dumb mistake when doing updates does not trigger the build. Marcus

To rule out clock problems, you should check the SNTP client that I announced - this was exactly why I wrote it. The ZTimestamp unit tests will only pass if the clock difference is not greater than 2 seconds. If the clock is wrong on the machine, on Linux you can do sudo ntpdate pool.ntp.org to manually force a date/time sync. > But then why did it fail on the mac? > > Marcus > >

Did you solve the problem that it was wasting ca. 4MB if memory because it had a copy of the complete catalog (everything but the files) on the client? Marcus
