Hi Bar,
Nice Work. Sergey has already done a fairly extensive review,
so there is nothing much for me to say. I just have two small
requests for clarification below...
... and sorry for taking sometime to finish this review.
STATUS
------
Approved after consideration of some minor issues.
REQUIRED CHANGES
----------------
n/a
REQUESTS
--------
R1. In my_base64_decoder_getch(MY_BASE64_DECODER *decoder)
The 'switch (decoder->state)' only asserts when the server
is built with debug info. What about production binaries ?
Shouldn't we at least return an error here (just to be
safe)?
R2. Why not make the base64_decode/encode signatures different?
So that they work similarly to other buffer handling/copying
functions like memcpy, strcpy (and like our own functions,
strmake, ...):
- first parameter : dest
- second parameter: source
- third parameter : len
- ...
+base64_decode(const char *src_base, size_t len,
+ void *dst, const char **end_ptr)
I know that you haven't touched in base64_encode function
in this patch, but is something for you to consider anyway.
NOTE: this is not a required change, it's a request for
clarification. So I am not considering this a show
stopper.
SUGGESTIONS

> - len Length of string at 'src'

> - DESCRIPTION
> -
> - The base64-encoded data in the range ['src','*end_ptr') will be
