cache-control : max-age=86400, no-store, must-revalidate, no-cache this response header set server js file. does mean response cached 86400 seconds before revalidating?. which of above 1 takes precedence , resiult?. looks no-cache give precedence on all. http1.1 specification says " if no-cache directive not specify field-name, cache must not use response satisfy subsequent request without successful revalidation origin server. " refer http://www.w3.org/protocols/rfc2616/rfc2616-sec14.html#sec14.9.1 it says " the max-age directive on response implies response cacheable (i.e., "public") unless other, more restrictive cache directive present.

i'm building ios app based on our goverment's open data, i use coredata store data, there 8 entities in xcdatamodel, some entity cotains 20000+ row of data's, , database read-only, i won't , user won't modify database, such delete/update/create, read-only database. the open data goverment keep update, isn't scheduled (and not often), , need let user update database if open data updated. i considering 1 best way update users database? 1) fetch json server, delete contents database, , insert again. disadvantages: a) risk high, user/system may terminate app while updating. b) lots of cost of network traffic 2) clear database, fetch entities data server on ios simulator, insert data, after that, copy database documents folder, put on server, let user download whole sqlite database, , cover old database. i think second 1 better, don't know take risk? or there disadvantages of method? thank you! if database heavy , , read-only,

i have 2 contexts , use snippet current context. snippet working properly, when use in getresources call, not passing snippet value.

when @ rust ascii operations feels there consistency issue between is_lowercase/is_uppercase: pub fn is_uppercase(&self) -> bool { (self.chr - b'a') < 26 } is_alphabetic: pub fn is_alphabetic(&self) -> bool { (self.chr >= 0x41 && self.chr <= 0x5a) || (self.chr >= 0x61 && self.chr <= 0x7a) } is there reason? 2 methods totally equivalent or missing something? these functions marked stable i'm confused. edit: to make clearer, expect decide on best (in terms of performance/readability/common practice) implementation lower/upper have pub fn is_alphabetic(&self) -> bool { self.is_lowercase() || self.is_uppercase() } since question changed performance, i'll add second answer. to start, created clone of ascii module ( playpen ): pub struct alpha(u8); impl alpha { #[inline(never)] pub fn is_uppercase_sub(&self) -> bool { (self.0 - b'a') < 26 }
