However, if you comment the first print statement and remove the commenting on the second and run the program again the capacity will only be 8. What is happening with sliceHeader.Data to make its capacity grow like that?
The runtime is free to make the slice of whatever larger-than-required capacity. The algorithm that picks a suitable memory block in the allocator is an implementation detail and the choice can be obviously influenced by the dynamics of the heap. IOW, the example program cannot expect any particular capacity that can be relied upon or even necessarily reproducible. -- -j -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
