I'm really concerned about silent breakage, however unlikely - that is also Simon and Robert's concern, and rightly so. If it's possible in principle to guard against a certain type of problem, we should do so. While this is a mechanical process, it isn't quite that mechanical a process - I would not expect this work to be strictly limited to simply spreading some functions around different files. Certainly, if there are any other factors at all that could disrupt things, a problem that does not cause a compiler warning or error is vastly more troublesome than one that does, and the most plausible such error is if a symbol is somehow resolved differently when the function is moved. I suppose that the simplest way that this could happen is probably by somehow having a variable of the same name and type appear twice, once as a static, the other time as a global. IMHO, when manipulating code at this sort of macro scale, it's good to be paranoid and exhaustive, particularly when it doesn't cost you anything anyway. Unlike when writing or fixing a bit of code at a time, which we're all used to, if the compiler doesn't tell you about it, your chances of catching the problem before a bug manifests itself are close to zero. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
