Tom Lane	fe838e5074	Limit values of archive_timeout, post_auth_delay, auth_delay.milliseconds. ... The previous definitions of these GUC variables allowed them to range up to INT_MAX, but in point of fact the underlying code would suffer overflows or other errors with large values. Reduce the maximum values to something that won't misbehave. There's no apparent value in working harder than this, since very large delays aren't sensible for any of these. (Note: the risk with archive_timeout is that if we're late checking the state, the timestamp difference it's being compared to might overflow. So we need some amount of slop; the choice of INT_MAX/2 is arbitrary.) Per followup investigation of bug #7670. Although this isn't a very significant fix, might as well back-patch.	13 years ago

Tom Lane	2594cf0e8c	Revise the API for GUC variable assign hooks. ... The previous functions of assign hooks are now split between check hooks and assign hooks, where the former can fail but the latter shouldn't. Aside from being conceptually clearer, this approach exposes the "canonicalized" form of the variable value to guc.c without having to do an actual assignment. And that lets us fix the problem recently noted by Bernd Helmle that the auto-tune patch for wal_buffers resulted in bogus log messages about "parameter "wal_buffers" cannot be changed without restarting the server". There may be some speed advantage too, because this design lets hook functions avoid re-parsing variable values when restoring a previous state after a rollback (they can store a pre-parsed representation of the value instead). This patch also resolves a longstanding annoyance about custom error messages from variable assign hooks: they should modify, not appear separately from, guc.c's own message about "invalid parameter value".	15 years ago
