apache - Do we really need to restart IIS 7 application pool? Do the same practice apply to other web servers? -

-

i wondering why restarting iis 7 application pool consider practice? know it'll clean orphan resources threads or session state, how other web server deal kind of problem? java developer/admin have restart weblogic/websphere/apache/tomcat every clean junk in memory?

typically it's used compensate bad programming. yours, third parties depending on libraries using.

and, recommendations, it's best @ specific environment see if it's necessary before doing it.

start profiling app. simple way let run while under load. things memory utilization settle down or continually grow?

if keeps growing, need set iis recycle every , go fix app. if grows point settles down should fine. make sure test edge cases of app.

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
