this bug still exist?
but in private model, only admin can publish, it seems like only need to disable admin sync by install ?

[hekike]

Yes, it works great with a forced:

this.session.allowSync = true;

[fengmk2]

@hekike I fix this stupid now.

@hekike
[email protected] had fix this bug.

[dead-horse]

this proxy still has one problem:

if run npm install package-a, and package-a dependencies is:

{
  "package-b": ">=1.0.0"
}

npm will try to install package-b, but if package-b in our registry only has 0.9.0, it can not install success. because npm will request http://registry.cnpmjs.org/package-b to check if has package-b@>=1.0.0, but the registry don't know this. so the npm can not found package-b@>=1.0.0 from our registry, then install failed.

Any update on this one?

install will trigger sync and return the package from source registry if this pacakge not exist in our registry.

but still can not make sure this install not fail.

[gergelyke]

I have syncByInstall: true in my config, and using version 0.3.10 - still doesn't trigger the sync. What am I missing?

[dead-horse]

the check middleware:

module.exports = function *syncByInstall(next) {
  if (!config.syncByInstall || !config.enablePrivate) {
    // only config.enablePrivate should enable sync on install
    return yield *next;
  }
  // request not by node, consider it request from web
  var ua = this.get('user-agent');
  if (!ua || ua.indexOf('node') < 0) {
    return yield *next;
  }

  if (this.query.write) {
    return yield *next;
  }

  this.allowSync = true;
  yield *next;
};

enablePrivate: true to make it as private mode ?

enablePrivate: true, // enable private mode, only admin can publish, other use just can sync package from source npm

i try with [email protected], it works fine
