No server start error checking

See original GitHub issue

If attempted on a system without java, or if the server failed to start for whatever reason, no error is raised until an action is attempted (checkTikaServer does not fail if the server fails to start).

Also, there is a sleep in startServer. Should make some actual calls to the server to check that its running correctly, i.e. spin-loop a request until it succeeds, or time/max-retry out.

happy saturday, @Purg and @chrismattmann!

i took a stab at this, adding:

  • custom java path (TIKA_JAVA env)
  • custom startup sleep (TIKA_STARTUP_SLEEP env)
  • custom startup retries (TIKA_STARTUP_MAX_RETRY env)
  • check for permission to write to tika-server.log (sometimes clients would touch/chmod to create tika.log but had not done so for tika-server.log)
  • check that TIKA_JAVA can be executed with subprocess.Popen
  • check that "INFO Started Apache Tika server at..." is present in log before return True

you can find it in my feature branch here:

commits here:

apologies for pycharm’s aggressive reformatting, but the real changes should be apparent in the constants, startServer, and checkTikaServer

if one of you would like to review and test, i can fix the cosmits and PR with just the relevant lines.
