git - Would directly copying a mongodb database causes problems? -


we push our project git , mongodb data files in committed directories.

we found when pull project onto machine, failed insert document collection. however, if drop collection , recreate collection same name, insertion success. why failed insert , why succeed again recreate collection?

i new mongodb, need help. thanks.

provided cleanly shutdown mongod in question, copying contents of --dbpath not problem. actually, considered valid practice backup purposes.

when copying files of running instance, copying lock files , journaling data deleted during clean shutdown. may prevent write access collections.

when delete collection, metafiles reset , of course can insert then.

so have do:

  1. shut down first instance cleanly
  2. add, commit , push contents of dbpath
  3. restart first instance
  4. shutdown target instance if running
  5. pull data
  6. restart target instance

c# - How do I get the Nth largest element from a list with duplicates, using LINQ? -

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
