[jruby-dev] [jira] (JRUBY-6804) Jruby cannot work with sendmail in a rails environment (or IO.popen does not function in jruby)

[Cris Shupp (JIRA)]

Cris Shupp created JRUBY-6804 Jruby cannot work with sendmail in a rails environment (or IO.popen does not function in jruby) Issue Type: Bug Affects Versions: JRuby 1.6.7 Assignee: Thomas E Enebo Attachments: email_test.rb, the_email.txt Components: Standard Library Created: 31/Jul/12 9:20 AM Description: Deploying a Rails application with JRuby to production is impossible due to the fact that JRuby has a bug when using IO.popen and sendmail.rb (%GEM_HOME%/gems/mail-2.4.4/lib/mail/network/delivery_methods/sendmail.rb) depends on this functionality. I have isolated the issue and have a tiny script that when run under MRI ruby will email. The same script, when run via jruby, has no errors and no email is ever sent. Monitoring of /var/log/maillog confirms this. Consider the following script (email_test.rb): def file_as_string(file) rVal = '' File.open(file, 'r') do |file_handle| file_handle.read.each_line do |line| rVal << line end end rVal end IO.popen("/usr/sbin/sendmail -i -t -f \"cristopher.sh...@va.gov\" cristopher.sh...@va.gov", "w+") do |io| email = file_as_string("/tmp/the_email.txt") io.puts email io.flush end #from sendmail.rb # def self.call(path, arguments, destinations, mail) # IO.popen("#{path} #{arguments} #{destinations}", "w+") do |io| # io.puts mail.encoded.to_lf # io.flush # end # end when run via MRI ruby as follows: /u01/dev/ruby_1.8.7/bin/ruby /tmp/email_test.rb Then sendmail's log (/var/log/maillog) is filled with activity, and an email arrives: Jul 31 09:11:25 vahdrtvapp05 sendmail[11520]: q6VEBO2a011520: Authentication-Warning: vahdrtvapp05.aac.va.gov: t192zcs set sender to cristopher.sh...@va.gov using -f Jul 31 09:11:25 vahdrtvapp05 sendmail[11520]: q6VEBO2a011520: from=cristopher.sh...@va.gov, size=359, class=0, nrcpts=1, msgid=<5017ded29f6c8_5487e267...@vahdrtvapp05.aac.va.gov.mail>, relay=t192zcs@localhost Jul 31 09:11:25 vahdrtvapp05 sendmail[11524]: q6VEBPPt011524: from=<cristopher.sh...@va.gov>, size=631, class=0, nrcpts=1, msgid=<5017ded29f6c8_5487e267...@vahdrtvapp05.aac.va.gov.mail>, proto=ESMTP, daemon=NoMTA4, relay=localhost.localdomain [127.0.0.1] Jul 31 09:11:25 vahdrtvapp05 sendmail[11520]: q6VEBO2a011520: to=cristopher.sh...@va.gov, ctladdr=cristopher.sh...@va.gov (1174/7400), delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=30359, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (q6VEBPPt011524 Message accepted for delivery) Jul 31 09:11:26 vahdrtvapp05 sendmail[11526]: q6VEBPPt011524: to=<cristopher.sh...@va.gov>, delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=120631, relay=mailproxy.aac.va.gov [10.238.10.254], dsn=2.0.0, stat=Sent (ok: Message 49228463 accepted) When run via jruby as follows: java -jar ./lib/jars/jruby-complete-1.6.7.2.jar /tmp/email_test.rb There is no output and sendmail's log remains silent.
