objective c - Detect old file name and new file name via FSEventsFramework -


i using fseventsframework monitor directories changes. wondering if logic here sound, detecting old file name , new name after rename.

  • i think on rename, both events in same callback.
  • old file name have event id x-1
  • new file name have id x

is true?

thanks

as far experienced it, assumption not true. on fseventstreamcreate pass latency flag meaning of latency kfseventstreamcreateflagnodefer. therefore events may or may not come in same callback. furthermore there different ways file can renamed. filesystem-apis rename file while keeping inode mv, others nsdocument create new inode. receive kfseventstreameventflagitemrenamed in callback, not.

edit: alternatives fsevents kernel queues , nsfilecoordinator

fsevents somehow not documented in api-docs. have @ header file fsevent.h, there more read there.

then see going on rename, run app , renaming finder, terminal mv in document based app using small triangle right filename.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
