java - SBT Set javac max heap -


i'm trying compile large java source files in scala/sbt project. how can set max heap size java compiler (javac).

setting

javacoptions in compile ++= seq("-target", "1.7", "-source", "1.7", "-xmx1g")

fails invalid argument exception on -xmx1g... setting -j-xmx2g give similar errors.

is there way can fork javac?

using sbt v 0.13.8

as you've noticed seems bug introduced in sbt 0.13.8, see #1968.

the workaround downgrade 0.13.7 doesn't happen.

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 ...
