我正在使用一个Rails 3.2应用程序，它有一个mysql数据库和许多在Solr中编入索引的模型。
以下是发生的事情：
我正在运行以下命令：
RAILS_ENV=development bundle exec rake sunspot:reindex[1000] --trace
在对400万条记录中的大约12％进行索引之后（尽管每次记录的百分比不同），该过程不可避免地会因以下错误和堆栈跟踪而爆炸：
rake aborted!

应用程序在localhost：3000的开发模式下运行，solr在localhost：8982上运行。这是我的solr.rake文件：
Rake::Task['sunspot:reindex'].enhance ['sunspot:scope_models_for_index']
Rake::Task['sunspot:solr:reindex'].enhance ['sunspot:scope_models_for_index']
namespace 'sunspot' do
task :scope_models_for_index => :environment do
require 'rsolr/error'
Dir.glob(Rails.root.join('app/models/**/*.rb')).each { |path| require path }
# Add the GC
commit_extension = Module.new do
def commit
GC.start
super
end
end
Sunspot.extend commit_extension
# Set all the models default scopes the index scope
Sunspot.searchable.each do |model|
model.class_eval do
default_scope ->{ sunspot_index } if model.respond_to?(:sunspot_index)
end
end
end
end
任何人都知道可能导致此错误的原因，或者如何修复它？
答案 0 :(得分：1)
显然问题是由于异常引起的：SocketError。
文件/Users/tchapin/.rbenv/versions/1.9.3-p392/lib/ruby/gems/1.9.1/gems/rsolr-1.0.9/lib/rsolr/connection.rb中发生异常：
def execute client, request_context
h = http request_context[:uri], request_context[:proxy], request_context[:read_timeout], request_context[:open_timeout]
request = setup_raw_request request_context
request.body = request_context[:data] if request_context[:method] == :post and request_context[:data]
begin
response = h.request request
charset = response.type_params["charset"]
{:status => response.code.to_i, :headers => response.to_hash, :body => force_charset(response.body, charset)}
rescue Errno::ECONNREFUSED => e
raise(Errno::ECONNREFUSED.new(request_context.inspect))
# catch the undefined closed? exception -- this is a confirmed ruby bug
rescue NoMethodError
$!.message == "undefined method `closed?' for nil:NilClass" ?
raise(Errno::ECONNREFUSED.new) :
raise($!)
end
end
这不是最漂亮的解决方案，它显然不是生产代码的解决方案，但我能够通过为SocketError异常添加救援处理程序来暂时解决问题，如下所示：
def execute client, request_context
h = http request_context[:uri], request_context[:proxy], request_context[:read_timeout], request_context[:open_timeout]
request = setup_raw_request request_context
request.body = request_context[:data] if request_context[:method] == :post and request_context[:data]
retries = 10
begin
response = h.request request
charset = response.type_params["charset"]
{:status => response.code.to_i, :headers => response.to_hash, :body => force_charset(response.body, charset)}
rescue Errno::ECONNREFUSED => e
raise(Errno::ECONNREFUSED.new(request_context.inspect))
# catch the undefined closed? exception -- this is a confirmed ruby bug
rescue NoMethodError
$!.message == "undefined method `closed?' for nil:NilClass" ?
raise(Errno::ECONNREFUSED.new) :
raise($!)
rescue SocketError => e
puts e
if retries > 0
puts "SocketError! Retrying connection after 1 second..."
retries -= 1
sleep(1)
retry
else
puts "SocketError: Not responding after 10 retries! Giving up!")
exit
end
end
end
此外，看起来我的Solr本地副本存在内存不足的问题。我通过相应地更新我的sunspot.yml文件解决了内存问题：
development:
solr:
hostname: 127.0.0.1
port: 8982
min_memory: 512M
max_memory: 2G
log_level: INFO
# open_timeout: 3
# read_timeout: 3
