amazon web services - aws s3 replace file atomically -


environment

  • i copied file, ./barname.bin, s3, using command aws s3 cp ./barname.bin s3://fooname/barname.bin

  • i have different file, ./barname.1.bin want upload in place of file

how can upload , replace (overwrite) file @ s3://fooname/barname.bin ./barname.1.bin?

goals:

  • don't change s3 url used access file (new file should available @ s3://fooname/barname.bin).
  • zero/minimum 'downtime'/unavailability of s3 link.

as understand it, you've got existing file located @ s3://fooname/barname.bin , want replace new file. replace that, should upload new 1 on top of old one: aws s3 cp ./barname.1.bin s3://fooname/barname.bin.

the old file replaced. according s3 docs, this atomic, though due ec2s replication pattern, requests key may still return old file time.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
