encoding/gob: decode map not eqaul encode value #20449
Comments

Hello there @niubaoshu, is the bug you are reporting that If so, my personal opinion is that that would be unexpected unless you have conflicting keys(in which that's implicit with a map for clashing keys); decoding values into a receiver is setting them in the receiver, and I don't see any promises of the proposed behavior in the encoding/gob docs Let me ping some of the owners of the package @robpike @bradfitz, to give some input. |

Hmm, interesting. For comparison with other encoding/ packages, I've made https://play.golang.org/p/rQyWHKZhIS. I'll defer to the decisions of the folks that I pinged earlier as I don't fully understand the correct behavior. Thank you for reporting the bug! |

Working as intended. The decoder does not zero out the object before storing the values. |
Please answer these questions before submitting your issue. Thanks!
