performance - Symfony2: class to compile with OPcache -

-

in symfony2, in extension file of bundle, possible call:

$this->addclassestocompile([class1, ....])

this adds given files cached file classes.php => can improve performances if put here used classes, because php process have find , process 1 file insteaf many.

but 5.6 version of php, there opcache can cache files , precompile them. guess symfony part isn't necessary anymore?

by using byte code cache php cache classes separately bootstrapped cache file. apc used years achieve this. php5.5 included opcache default handle opcache. apc enabled users add cache items itself, opcache not available users.

because of that, apcu split original apc library traditional user caching becomes available > php5.4. more info symfony performance can found in the book's performance chapter.

to answer question symfony bootstrap: if use both bootstrap caching , bytecode cache, adding files bootstrap result bigger bytecode cache file. if application has classes (like kernel.request listeners) used in every request, adding them bootstrap makes sense. otherwise add overhead to, , marginally slow down other requests.

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.
