java - Is File instance thread safe? -


I've read that new file ("path") does not physically make a file on disk is . Although it is said in the API:

Examples of this class may or may not be an actual file-system object such as a file or directory. If such an object specifies, that object remains in a partition. A partition is a operating system-specific part of storage for a file system, a single storage device (eg a physical disk-drive, flash memory, CD-ROM) can have multiple partitions < P> So I'm curious if such a code is safe in a multithrred environment: 

  file file = new file ("myfile.zip"); // Take some action with file (fill it with content) file.save (anywhere); // Simply show that I save it after a number of tasks   
 For example, Thread 1 comes here, creates an example and is starting to work Meanwhile, In thread 2, it is interrupted, the example makes  by the same name  (myfile.zip) and performs some other operations. After that he saved the file.  
 I need to make sure that they do not work with the same file and the previous thread overwrites the previous one to save the file.   
 
 
 No, the file does not keep locked and is not safe for the pattern you describe. File should be locked or placed in the wrapper class.  
 If you provide a bit more code, then one can definitely help you find a suitable pattern.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
