--ControlPortWriteToFile reports port 0 on --ControlPort=auto, not opened port

If I start the latest tor code with --ControlPort=auto and --ControlPortWriteToFile=/path/to/file, then the contents of the file end up as PORT=, which is kind of useless :)

I guess some code got messed up lately that updates the port before writing it out to the control file.

Hi, thanks for this bug report.
Which branch and commit are you using?

Questions for the developers:
Are we writing the file before we assign and open the control port?
Or did we change one of the control port functions in the refactor?

What was the last version that worked?
Does this issue happen with Tor 0.3.3 or Tor 0.3.4?

I have a fairly funky build setup, I pulled latest master where this issue was happening (not sure when it started, just started using Tor now). If I revert to latest stable (, then everything works fine. Didn't test 0.3.4 as it conflicts with my builder.

I can confirm that 0.3.4 has this problem too, and 0.3.3 does not.

Git bisect tells me that 6ed384b827dce21ea3a44b58792cc28b2ed48056 was the first bad commit.

I think removing the gotPort field here was wrong.
