From e2c0e51e4545a7e373aad3650048e0a50497e108 Mon Sep 17 00:00:00 2001 From: Shaun McDonald Date: Thu, 20 Nov 2008 21:23:44 +0000 Subject: [PATCH] Closes #1350 through updating amf_controller to use the newer closed_at method of determining whether a changeset is closed. Richard please check the rest of the amf controller for more things that may reference the open field that is no longer available. Use is_open? to determine if a changeset is open. Fix indentation in amf controller. Fix minor bug in the links to changesets in the data brower. --- app/controllers/amf_controller.rb | 869 ++++++++++++------------ app/controllers/changeset_controller.rb | 2 +- app/models/changeset.rb | 6 +- app/views/browse/_common_details.rhtml | 2 +- 4 files changed, 441 insertions(+), 438 deletions(-) diff --git a/app/controllers/amf_controller.rb b/app/controllers/amf_controller.rb index 6e1b364d4..589005d3c 100644 --- a/app/controllers/amf_controller.rb +++ b/app/controllers/amf_controller.rb @@ -45,83 +45,84 @@ class AmfController < ApplicationController # ** FIXME: refactor to reduce duplication of code across read/write def amf_read - req=StringIO.new(request.raw_post+0.chr)# Get POST data as request - # (cf http://www.ruby-forum.com/topic/122163) - req.read(2) # Skip version indicator and client ID - results={} # Results of each body + req=StringIO.new(request.raw_post+0.chr)# Get POST data as request + # (cf http://www.ruby-forum.com/topic/122163) + req.read(2) # Skip version indicator and client ID + results={} # Results of each body - # Parse request + # Parse request - headers=AMF.getint(req) # Read number of headers + headers=AMF.getint(req) # Read number of headers - headers.times do # Read each header - name=AMF.getstring(req) # | - req.getc # | skip boolean - value=AMF.getvalue(req) # | - header["name"]=value # | - end + headers.times do # Read each header + name=AMF.getstring(req) # | + req.getc # | skip boolean + value=AMF.getvalue(req) # | + header["name"]=value # | + end - bodies=AMF.getint(req) # Read number of bodies - bodies.times do # Read each body - message=AMF.getstring(req) # | get message name - index=AMF.getstring(req) # | get index in response sequence - bytes=AMF.getlong(req) # | get total size in bytes - args=AMF.getvalue(req) # | get response (probably an array) + bodies=AMF.getint(req) # Read number of bodies + bodies.times do # Read each body + message=AMF.getstring(req) # | get message name + index=AMF.getstring(req) # | get index in response sequence + bytes=AMF.getlong(req) # | get total size in bytes + args=AMF.getvalue(req) # | get response (probably an array) logger.info "Executing AMF #{message}:#{index}" - case message - when 'getpresets';
