amazon web services - create empty folder S3 ruby SDK -

-

i want create empty folder in amazon s3 using ruby sdk. ive read there no folder concept in s3, theoretically create folder create empty object trailing "/"

s3 = aws::s3::client.new( region: 'eu-west-1',                           credentials: creds)  s3.put_object(bucket: "my_bucket",               key: "my_folder/")

doing creates empty object on bucket, if try upload file this:

s3.put_object(bucket: "my_bucket",               key: "my_folder/myfile")

it doesnt create file in my_folder. maintains old empty object, , creates folder , file. after 2 commands bucket structure is:

my_bucket/   my_folder   my_folder/     my_file

why happening? why create object my_folder twice? how should create empty folder later use?

the amazon s3 virtual folders spring existence when key contains '/'. when browsing bucket in s3 console, scans object keys common prefixes , uses prefix show subset of bucket.

given following object keys:

  • photos/family/reunion.jpg
  • photos/family/vacation.jpg
  • videos/funny.mp4

then amazon s3 show top level folders "photos" , "videos". if delete "videos/funny.mp4" object, "videos" directory disappear.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
