firefox addon sdk - Set preferences in the user branch and unset them on uninstall -


i created firefox add-on following lib/main.js:

const {cc,ci} = require("chrome"); var pref = cc["@mozilla.org/preferences-service;1"].getservice(ci.nsiprefbranch); pref.setintpref("network.http.response.timeout", 3600*24);

it wasn't accepted following reason:

add-ons change critical settings must revert changes when disabled or uninstalled. should make changes in default, rather user, branch.

you need call getdefaultbranch("") on preferences service, , call preference methods on returned object rather on preference service directly.

to revert preference default, set setintpref(), found out have this on uninstall:

pref.clearuserpref("network.http.response.timeout")

this command works fine if call in test-addon. have find out how implement command, executed when firefox-addon uninstalled?

so how have understand these comments? how set preferences in "user branch"?

i solved the second part (uninstall) this, in main.js added code @ end:

exports.onunload = function(reason) {     //called when add-on      //    uninstalled     //    disabled     //    shutdown     //    upgraded     //    downgraded     pref.clearuserpref("network.http.response.timeout"); };

that worked on disabling , uninstalling add-on.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
