Does .NET JIT compiler generate different code for generic parameterized with different enums? -

-

if write (or use) generic class, e.g. list, , parameterize 2 different enumerated types, 2 copies of code jitted? given following articles discuss how jitter generates 1 copy reference types, , 1 copy each value type, think boils down to, "is each specific enum considered different value type purpose of jitting?"

clr vs jit

http://msdn.microsoft.com/en-us/library/ms379564%28v=vs.80%29.aspx#csharp_generics_topic1

in c# code:

using system.collections.generic;  namespace z {     class program     {         enum {a}         enum b {b}         class c<t>         {         }          static void main(string[] args)         {             var x = new c<a>();             var y = new c<b>(); // jit new c constructor enum type b?         }     } }

i'm interested know in general, .net cf 3.5 (windowsce) jit compiler (edit: because i'm interested in possible code bloat implications). suggestions on best way find out? thinking of writing function in class c p/invokes native code, can break debugger , examine callstack - return address, perhaps can answer authoritatively based on language rules of i'm not aware...

so went ahead , put p/invoke function call c<t>.test function. broke debugger (desktop windows supporting managed , native debugging) in native function, dropped assembly, tracked past ret instruction native function. eip (instruction pointer) after ret consistent returning 2 different routines, 1 c<a>.test, , other c<b>.test. multiple calls through these 2 functions common native function (with breakpoint) showed consistent results. further, post ret eips 0x2e0246 , 0x2e02be, near each other , not mapped loaded dlls's address space. indicates me jitted, , jitted close in time each other, , size of jitted methods small (as expected).

so answer, @ least desktop, generics templated different enums jit different routines.

my group , running server based upon django , uses mod_wsgi run apache server. not working on project after over, attempting set cronjob similar functionality check if apache server has shut down(system restart or power failure), , if has, restart server me. i've found documentation on how check if apache server down , restart server if is, our server uses https , our start command pretty verbose. can use functionality provided in these examples: https://askubuntu.com/questions/277389/cron-job-to-restart-apache https://www.digitalocean.com/community/tutorials/how-to-use-a-simple-bash-script-to-restart-server-programs or need more complicated process make happen? the command use start server is python manage.py runmodwsgi --host 0.0.0.0 --port 8001 --https-port 8000 --ssl-certificate (certificate location) --server-name (domain name) i'm pretty new linux , using both mod-wsgi apache appreciated. you better off using --setup-only option mod_wsgi-expres...

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
