Re: [Pharo-dev] Source code formatting guidelines

by Jan Vrany

Hi guys, thanks for replies. I read books mentioned by Christophe years ago, they're worth reading indeed. But as I said, I'm more interested in 'low level' details like I mentioned: - tabs/spaces? How many spaces if spaces? - encoding of the source string - trailing newlines - trailing spaces - ... The reason is I'm now working with Jan K. on some stuff and he's using Pharo while I don't. To exchange code I read his .mcz when merging his changes and generating .mcz for him when he has to merge my stuff. However, Pharo's merge tool apparently does not do a really great job when it comes to whitespace changes so the merge is difficult and error-prone. The idea is to transform the source just before spitting out the .mcz to minimize these false-diffs when one try to merge.

no ideaâ¦ but in a philosophical point of view, the fact that you have an accessor doesnât means that you should have a mutator ;) Esteban > On 20 Nov 2014, at 13:51, Noury Bouraqadi <bouraqadi(a)gmail.com> wrote: > > Hi, > > > Is there any reason why we donât have this method > > Message>>#arguments: anArray > args := anArray > > We already have the read accessor.

Hi, Is there any reason why we donât have this method Message>>#arguments: anArray args := anArray We already have the read accessor. There is also a write accessor for single argument messages. Any hint? Noury

So very early at startup the system does some allInstances invocations on the classes of handles and invalidates all the handles found. This doesn't fix handles stored as raw integers anywhere, but provided the system is designed to have specific objects for external handles (and I hope it is) this shouldn't happen. Since snapshot is relatively rare and start-up relatively frequent (at least in e.g. a web deployment context), one performance improvement is to do the allInstances before snapshot, and then merely enumerate the collection of handles, rather than use allInstances. Just to add: - (re)validating external resources could vary depending on library or how short/long-lived the resource is etc. As you described, one of the scenarios is to flush invalid handles at system startup. In NB i using session checking, to do it lazily, once there's an attempt to use external resource. But all that, of course, doesn't addresses the problem when external resource get invalidated, for one or another reason, during same session. Using proxy to control each and every access to external resource is, of course, an ultimate solution, but alas, quite expensive since imposes high overhead. I would call it a brute-force solution. To minimize overhead, my approach often is to place a check at key entry part of algorithm, so if check passed, then rest of algorithm can run safely without excessive checking. But that really depends on design of external library/framework, whether it possible or not. Usually, if you cleverly organize the access to services, it is possible to do it without using brute-force proxyfying.

So I create some external objects and apply some functions on them. If the handle to the object is not valid, either the function crashes or gives a bad result. How can I ensure to have a valid pointer at anytime ? I see two solutions: - Either check at any NativeBoost call that the handle is valid (by checking the session id) - Or do a proxy that checks the session and recreate the external object.
