node.js - "Can't set headers after they are send" even though the code isn't doing it -


i'm using express 2.5.8 (not want to), , node 0.8.15 (again, i'd love upgrade).

here's piece of code:

unless apikey   res.writehead 400, { "content-type": "text/plain" }   res.end "api key must provided api access."   return

edit: broke writehead statuscode , setheader, , worked. know why?

working code:

unless apikey   res.statuscode = 400   res.setheader "content-type", "text/plain"   res.end "api key must provided api access."   return

end edit

i know being executed, , return works, because when try

unless apikey   res.end('wtf')   return   res.writehead 400, { "content-type": "text/plain" }   res.end "api key must provided api access."   return

i 'wtf' without server crashing.

when try

unless apikey   res.writehead 400, { "content-type": "text/plain" }   return   res.end "api key must provided api access."   return

i wait forever , timeout, writehead part works, , when try

unless apikey   # res.writehead 400, { "content-type": "text/plain" }   res.end "api key must provided api access."   return

i right response.

so why can't original code work???

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
