how to change default mirror url pypi.python.org/simple/ with devpi-server

[robertding]

i start devpi-server version 4.3.0 as cache server
with cmd devpi-server --serverdir /root/packages/ --port 5555 --host=0.0.0.0 --start
how can i change the default cache mirror?

What do you mean by "default cache mirror"? Do you mean the URL pip uses, or the URL for the PyPI cache?

sorry i didn't make it clear. i want to change the default url pypi.python.org/simple/ to another mirror url like mirrors.aliyun.com when a package not accessable in my devpi server.

@fschulze sorry i dont exactly know the differnet between pip uses(client side usage?) and PyPi cache.
I tried to modify the pip.conf in my devpi server, but it didn't work. The devpi server still tring to get missing package from pypi.python.org which is far slow in my country.
I tried to modify the source code config.py under devpi_server, still not working. Thanks for your help.

You can change mirror_url on the root/pypi index. Something like this should work (from my head, untested): devpi index root/pypi mirror_url="...". It must point to the simple index of the mirror.

Did my answer solve your issue?

i have the same requirement
is this contol download package from ?
in you reply, how to "change mirror_url on the root/pypi index"?

server/devpi_server/extpypi.py line 118?

@fschulze

class PyPIStage(BaseStage): def __init__(self, xom, username, index, ixconfig): super(PyPIStage, self).__init__(xom, username, index, ixconfig) self.httpget = self.xom.httpget # XXX is requests/httpget multi-thread safe? self.cache_expiry = self.ixconfig.get( 'mirror_cache_expiry', xom.config.args.mirror_cache_expiry) self.xom = xom if xom.is_replica(): url = xom.config.master_url self.mirror_url = url.joinpath("%s/+simple/" % self.name).url else: url = URL(self.ixconfig['mirror_url']) self.mirror_url = url.asdir().url

and i have try to change mirror_url in main.py/_pypi_ixconfig_default/, it doesn't work

You don't have to change code, use the devpi client to set the option on the index. For example to change the url for root/pypi:

devpi index root/pypi mirror_url="..."

@fschulze i think you have not understand my mean. normally, when someone install a package that haven‘t cached in devpi server, the devpi server when download the package from pipy.python.org. but we are in china, the speed is slow. so i expect the devpi server download package from pypi.doubanio.com/simple but not pypi.python.org. this should be work on devpi server but not client.

That's exactly what I'm saying. If you run devpi index root/pypi you should get something like this:

% devpi index root/pypi
https://d.rzon.de:8141/root/pypi:
  type=mirror
  volatile=False
  mirror_url=https://pypi.python.org/simple/
  mirror_web_url_fmt=https://pypi.python.org/pypi/{name}
  title=PyPI

Now you run devpi index root/pypi mirror_url="https://pypi.doubanio.com/simple/" and you should get something like:

% devpi index root/pypi mirror_url="https://pypi.doubanio.com/simple/"
/root/pypi changing mirror_url: https://pypi.doubanio.com/simple/
https://d.rzon.de:8141/root/pypi:
  type=mirror
  volatile=False
  mirror_url=https://pypi.doubanio.com/simple/
  mirror_web_url_fmt=https://pypi.python.org/pypi/{name}
  title=PyPI

Now packages will be downloaded from the mirror instead of regular pypi.

@fschulze
I run devpi server by supervisor, and the command is :" /data/virtualenv/devpi/bin/devpi-server --port 404%(process_num)d --serverdir /data/project/devpiserver --outside-url=http://pypi.xxxxx.com".
how to run devpi index root/pypi mirror_url="https://pypi.doubanio.com/simple/"? there has no args like 'mirror_url'.

[fschulze]

You need devpi-client for that, it's not a command line option of the server, but a setting in the database of the server, which you can manipulate with devpi-client. See documentation, starting with https://devpi.net/docs/devpi/devpi/stable/+d/quickstart-releaseprocess.html
