lib/net/protocol: clear short-lived read buffer
Using a parallel Net::HTTP downloader, this reduced memory usage
from around 120MB to 50MB on my 32-bit x86 system.
Test script I used:
require 'net/http'
require 'uri'
require 'digest/sha1'
url = 'http://80x24.org/git-i-forgot-to-pack/objects/pack/pack-97b25a76c03b489d4cbbd85b12d0e1ad28717e55.idx'
uri = URI(url)
use_ssl = "https" == uri.scheme
thrs = 30.times.map do
Thread.start do
cur = Thread.current.object_id
Net::HTTP.start(uri.host, uri.port, use_ssl: use_ssl) do |http|
req = Net::HTTP::Get.new(uri)
http.request(req) do |res|
dig = Digest::SHA1.new
res.read_body do |buf|
dig.update(buf)
#buf.clear # most Ruby programmers don't do this :<
end
warn "#{Time.now} #{cur} #{dig.hexdigest}\n"
end
end
:done
end
end
