Description Sergey S. Starikoff 2011-04-27 05:50:47 UTC
Currently my workstation has web access via proxy server (squid) with basic auth.

Using emerge-webrsync fails without any error message info. At the time, where it should be.

Overwriting in /etc/make.conf default values of FETCHCOMMAND and RESUMECOMMAND variables adding --proxy-user and --proxy-password options make emerge-webrsync operates normally.

Reproducible: Always

Steps to Reproduce:
1. Set up web access via proxy-server using basic auth mech;
2. Try to sync portage tree over proxy using emerge-webrsync utility.
Actual Results:

You could ask to get bug #104547 reopened.

*** This bug has been marked as a duplicate of bug 104547 ***
Comment 2 Sergey S. Starikoff 2011-05-06 07:44:08 UTC
I disagree with marking this bug as duplicate of 104547.
104547 is enchancement request for proxy in general.

This bug is about that emerge-webrsync fetch portage archive function (unlike distfiles fetch) incorrectly handles proxy error codes (or doesn't handle them at all) in the case with usind squid proxy server with authorized (basic mech is used) web access.

This bug is not enchancement request, it's the issue report!

That seems like a reasonable solution. So, doesn't that solve your problem?

It not seems, it is the solution of the issue in the part of _operability_. :)

But the bug is not about portage operability (it works fine ;) ), it's about handling and reporting errors (I've rememebered that it's a time to redefine FETCHCOMMAND and RESUMECOMMAND variables only after reading emerge error while trying to install app-portage/emerge-delta-webrsync, not error message of emerge-webrsync).
Normally emerge-webrsync should provide error message similiar with emerge.
Comment 5 Zac Medico gentoo-dev 2011-05-09 19:12:20 UTC
The thing is, in order for FETCHCOMMAND and RESUMECOMMAND to be useful, portage needs to make as little assumptions about them as possible. It's not really feasible to make assumptions about error codes, since we don't want to assume that FETCHCOMMAND calls wget rather than curl or whatnot.

So, I think the best that we can do allow the message from FETCHCOMMAND to pass through. Looking at the code, the fetch_file() function doesn't seem to redirect output, so I don't understand why you didn't see any output from FETCHCOMMAND.

emerge fetch function checks result and normally translates FETCHCOMMAND messages.

emerge-webrsync fetch function doesn't check the result (were queried files fetched or not) and all errors (including proxy authentification errors) interpreters as file, not present on a mirror (at the time, where emerge fetch function translates proxy error message).
