Why would executing "hg push" be failing as shown below?

Question

My hgrc file contains the following information:

[auth]
default.prefix = bitbucket.org
default.username = stephen-paul-chappell
default.password = ******************************
default.schemes = http https
proxy.prefix = wsa-sn.pcci.edu
proxy.username = 116042
proxy.password = ********
proxy.schemes = http https
[http_proxy]
host = wsa-sn.pcci.edu:3128
user = 116042
passwd = ********
[paths]
default = https://bitbucket.org/stephen-paul-chappell/praecipuas-tournament
[ui]
username = Stephen Chappell <[e-mail]>

The information that shows up on standard output is as follows:

C:\Users\Zero\PycharmProjects\praecipuas-tournament>hg push --verbose --debug --traceback

I am not sure what is going wrong exactly or how to fix the problem.

Answer 1

It looks like an issue with your proxy:

  File "urllib2.pyo", line 911, in http_error_401
  File "mercurial\url.pyo", line 453, in http_error_auth_reqed
  File "urllib2.pyo", line 889, in http_error_auth_reqed
  File "mercurial\url.pyo", line 464, in retry_http_basic_auth
  File "urllib2.pyo", line 431, in open
  File "urllib2.pyo", line 449, in _open
  File "urllib2.pyo", line 409, in _call_chain
  File "mercurial\url.pyo", line 372, in https_open
  File "mercurial\keepalive.pyo", line 255, in do_open
URLError: <urlopen error ''>

So this shows a the proxy throw a 401 asking for authentication, so HG tries again (retry_http_basic_auth), but after that it seems to fail. I'm assuming you need the proxy, but are you able to try from a host that does not need the proxy just to make sure your mecurial repo is sane?

Also this SO question covered something similar and traced it to an issue with their load balancer not handling the size of the HTTP headers, which might be something else to look at (i.e., is the proxy not handling the HTTP headers correctly?)
