The benefit comes when they both start.
There's two side of this approach I don't really agree with. First it's easier and faster to have a step by step plan than to decide to do nothing unless you can get everything at once. With the second approach, you will have a great result when you deploy, but you will definitively deploy a lot later (not only the intermediate steps will be faster, but you will get the full solution later than with the first approach, because you will have to integrate and solve all the problems at the same time, you will motivate less people to get involved, and you will require more full-time involvement of the resources to get things to happen). Also if Fx waits for it to happen in Tb, and Tb waits for it to happen in Fx, it will never happen. Second I think they probably are some gains, even if minor, to switching to sqlite3 other than being able to share with another app. - The memory usage/code size front is a side where there could be gains : it's not easy because you need bdb to still be there somewhere to convert the old bases, but the code can be unloaded just after the application has started - Aren't they some progress on the stability front with sqlite3 ? It's fully ACID, bdb is not, are we sure they are not some points where a crash can leave the bdb data corrupted and sqlite3 will help ? - Outside of sharing the db, it would be a step toward enabling several instances to use the same profile. I know this will not happen any time soon, but it will be a really good thing to allow it some day, and every step counts. - If the format changes and there's an option in firefox to put the db outside of the profile directory (like it's possible to put the mail file outside of it), people making an enterprise deployment and advanced hackers can start sharing db with the official version of firefox/thunderbird, even if it requires much manual tuning. Those people can even end up providing some experience returns when the full scale solution is conceived. One thing I'll do now is to open a core/PSM bug for allowing the db to be outside the profile directory :-) _______________________________________________ dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
