c++ - Design pattern suggestion for storing the client information in map in server application -

-

my application server, , client give request processing. client contact me(server) multiple times handling same request .

map<clientid,clientinformation>

usually, i'll store information received client in stl map processing client request next time.

once client satisfied in servings, clear entry in map respective client id.

this sample clientinformation class:

class clientinformation { int notrequiredfornexttime;  // information not required  processing client request next time int requiredfornexttime;  // information required  processing client request next time int requiredfornexttime;  // information required  processing client request next time int notrequiredfornexttime;  // information not required  processing client request next time int notrequiredfornexttime;  // information not required  processing client request next time  userdefinedclass class1; };  class userdefinedclass { int requiredfornexttime; int notrequiredfornexttime; }

in above class, require requiredfornexttime stored in map. other information required @ time of processing current request.

clientinformation class can have user-defined class member(userdefinedclass), , of userdefinedclass members not required next time.

is there design pattern, provided optimized solution(memory usage) problem?

in case, separate required- notrequired- fields, in separate classes. could...

  • have notrequired- class held pointer in required class, such delete it, or

  • have required- class held pointer in notrequired- class, such move out distinct container, or

  • keep them in separate containers right start, or

  • write code construct required class clientinformation class - copying required fields (copying inefficient, might require less change existing code, if have any).

    • "serialisation" 1 form of this, albeit in data's not kept in accessible structure during storage, , distinct deserialisation step needed recreate required class, or perhaps repopulate required fields of clientinformation object

(i'm not aware of relevant design pattern names, not programmer needs validated design pattern name - developing mental awareness of data modelling options means can apply "common sense", named or anonymous.)

yii2 - Yii 2 Running a Cron in the basic template -

-
i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
