asp.net - Sys.WebForms.PageRequestManagerTimeoutException during server-side debug -

Image
often during debug of server-side vb.net/c# code executed inside of asp.net partial postack (updatepanel, other controls ajax behaviors) getting client-side error: at point not care client-side (and @ runtime not happening). it's major annoyance during debug - there way prevent it? this happens when have asp scriptmanager ajax processing. control has default async postback timeout of 90 seconds, after throw exception. the solution rather simple: add asp tag during debug extend timeout long debug session might take you: <asp:scriptmanager id="scriptmanager1" runat="server" asyncpostbacktimeout="3600"> </asp:scriptmanager> the above let me run debug session 1 hour before throwing exception. don't forget remove tag production releases, or hung loop etc, never time out. jeff

pycharm - How to specify that a parameter is a list of specific objects in Python docstrings -

-
i using docstrings in python specify type parameters when projects beyond size. i'm having trouble finding standard use specify parameter list of specific objects, e.g. in haskell types i'd use [string] or [a]. current standard (recognisable pycharm editor): def stringify(listofobjects): """ :type listofobjects: list """ return ", ".join(map(str, listofobjects)) what i'd prefer: option 1 def stringify(listofobjects): """ :type listofobjects: list<object> """ return ", ".join(map(str, listofobjects)) option 2 def stringify(listofobjects): """ :type listofobjects: [object] """ return ", ".join(map(str, listofobjects)) i suppose wasn't great example - more relevant use case 1 objects in list must of specific type. better example class food(object): def __init__(self, cal...

-
i using myapp::application.config.session_store :active_record_store in application store sessions in database. works fine. however, i'd able load specific session when passed session_id . value server stores cookie on client side. my rails application has client can't use cookies, has pass me session_id in parameter. i'd use before_action or sort of filter take parameter , use load session in controllers instead of app loading null session due lack of proper cookies. is there way can this? don't want turn off cookie method altogether because web client uses cookies, it's mobile client can't. edit: if declare class session < activerecord::base , session.find_by_session_id('whatever') session activerecord object, i'm not sure how make usable session in normal rails sense. just request.session_options[:id] = "whatever want" in before_action filter , rails use session_id load session when access (thanks lazy l...

logic - Does PHP if statement assume you are checking for 'true' if left blank? -

-
i once thought read somewhere if have php script this: public function test($something){ if($something == "true"){ return true; }else{ return false; } } if(test("true")){ echo "returned true"; } then should work fine if statement assumes checking if true when left blank? true, , if 'good programming' leave blank or should finish off statement sake of not cutting corners? if($variable) is pretty saying if($variable != null && $variable != false && $variable != 0) so long variable set , not equal 0 or false evaluated true "and if 'good programming' leave blank or should finish off statement sake of not cutting corners?" if trying evaluate equal true, cutting corners, pretty common use if($variable) confirm $variable defined value

Tell "ls -laR /": do not recurse into other filesystems -

-
i "ls -lar /" on system , offsite backup results. if disaster strikes, i'll @ least know files i've lost. i started sshfs mounting remote systems, yielding 2 problems: "ls -lar" on sshfs mounted systems painfully slow i don't need "ls -lar" results of remote filesystems, @ least not locally. what's ls equivalent of find's "-xdev" option or du's "-x" option? in case there's better way it, goal efficiently list of files on hard drive size, owner, mod time, etc. in other words, info "ls -l" provide. i've considered: "find / -xdev | xargs ls -la", sense less efficient. there no such option ls itself, can do find / -xdev -ls or if not sufficiently detailed, possibilities offered -printf option.

php - Binding issues of slash with quotes -

i using php mysql-pdo , symfony issue : have query stated below status in (:status) with value of status a','b . and when bind sting escaping below status in ('a\',\'b') and hence wrong output. pleass help prepared statement can represent complete data literal only . not part of literal, nor complex expression, nor identifier. either string or number only. thus, query doesn't work binding complex expression, not because of quotes one have create query placeholders representing every array member, , bind array values execution: $ids = array(1,2,3); $stm = $pdo->prepare("select * t id in (?,?,?)"); $stm->execute($ids); to make query more flexible, it's better create string ?s dynamically: $ids = array(1,2,3); $in = str_repeat('?,', count($arr) - 1) .
