well I was looking into mercurial.py in admin/controllers and mercurial's python api I can see ui.quiet is set in our mercurial.py implementation. That should be fixed this issue.
But we know it doesn't See http://code.google.com/p/modwsgi/wiki/FrequentlyAskedQuestions and search for "Why do I get the error 'IOError: sys.stdout access restricted by mod_wsgi'?" some possible workarounds at apache level. @whoever in charge of mercurial support: Also, from what I've read in the mercurial api, if ui.quiet set then mercurial.ui.status() method (called inside mercurial.cmdutils) will suppress writing to output, if --quiet is passed in. (like "hg addremove --quite") Can we pass this argument to mercurial.cmdutils.addremove()? If yes, I think, it'll fix the problem. I don't know who's in charge of mercurial support, (so if anyone know, please forward a copy to him/her for quick attention) @Manuele: in meanwhile, try the link provided and also try add following to your global .hgrc file (actually it's done with api in admin/conttrollers/mercurial.py but trying will not hurt :) ) [ui] quiet=True
