[vwnc] BOSS for 64bit images
 
|
Anyone here who've already implemented functionality for the 64bit
LimitedPrecisionReals in BOSS, or know if Cincom plan to support it? Issues I've run into so far: - The new SmallDoubles don't like to be stored (BOSS assuming all immidiates can be stored as long, and hardcoding encoding for known immidiates) - Loading Doubles saved by a 32bit image causes errors as well (changeClass: fails since 1.0d is now immidiate).

64 bit BOSS is being worked on as part of the 64 bit support.

Henrik,
As James mentioned, we're currently working on this. What we have now is a prototype which solves several issues with 64 bit images, including the two you mentioned. Images of 32/64 bits can read boss files in 64/32 bit format. We also have the ability for 64 bit images to write boss files in 32 bit format. Right now we're working on making what we have better so it becomes easier to maintain in the future.

Henrik,
if you are a Cincom Support Customer, then I have a good message for you. We have developed a working solution that solves the SmallDouble vs. Double conflict. It also handles the conflict for SmallInteger that exceed the 32 bit range. The basic idea of BOSS is kept: It is a cross-platform interchange format to be written from any platform and correctly be read into any other platform. Our solution has been tested successfully but is pending for Cincom Engineering quality assurance and integration. Very likely, the upcoming VisualWorks version 7.7 will include this solution or a better one from engineering. You can find the solution with your customer support web access.

A suggestion, using SQLite as file system resolves many issues :)

Sure, unless you're dealing with existing apps, in which backwards
compatability is nice to have, (ie: need to read from BOSS in any case) and ROI on changing file storage format can be hard to justify. As my first issue with Cincom in the formal role of customer, I'm quite satisfied with how the issue was resolved anyways. ;) Cheers, Henry Jim Guo wrote: > A suggestion, using SQLite as file system resolves many issues :) > > On Thu, Dec 18, 2008 at 8:59 AM, Valloud, Andres <[hidden email] > <mailto:[hidden email]>> wrote: > > Henrik, > > As James mentioned, we're currently working on this.
