I've been finding various different regexes being used for extracting/matching ASF availids.
So it struck me it might be useful to define the RE string once in the asf/whimsy library. e.g. assuming the most restrictive useradd [1] rule: AVAILID_RE = '[a-z_][a-z0-9_-]*[$]?' However this is too general; we don't want to allow '$' (not currently used in any ids) and care needs to be taken with '-' because of INFRA-11485 / INFRA-7390.single Maybe we need two REs: 1) matching all possible existing ids; some of these contain hyphens; some service accounts start with _ 2) a stricter version for adding new accounts - e.g. we don't want to allow hyphen because of INFRA-11485 and we probably don't want to allow _ either Possibly also define some methods if there seem to some common usages once the constants are in place. It would certainly be useful to have a single shared uidValid? method. Thoughts? [1] http://www.unix.com/man-page/linux/8/useradd/
