commit https://github.com/vim/vim/commit/fcaaae6b3fdbf3421a1ff95a25ae16d82381c39a Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 24 16:49:11 2016 +0100 patch 7.4.1166 Problem: Can't encode a Funcref into JSON. jsonencode() doesn't handle the same list or dict twice properly. (Nikolay Pavlov) Solution: Give an error. Reset copyID when the list or dict is finished.

/* crypt_zip.c */
void crypt_zip_init(cryptstate_T *state, char_u *key, char_u *salt, int salt_len, char_u *seed, int seed_len);
void crypt_zip_encode(cryptstate_T *state, char_u *from, size_t len, char_u *to);
void crypt_zip_decode(cryptstate_T *state, char_u *from, size_t len, char_u *to);
