Lets reduce string comparisons here. 2022-06-27 03:03:22 +04:00
Alexander Andreev 149675cd86
Fixed mutexes. Now program doesn't fall under high load. 
Seems like an old expiry comparing didn't work as left thousands of expired captchas in a map, so it was replaced by a forgotten by me time.Since() function.

When I moved implementation to pkg directory an error appeared that DwellingCaptcha doesn't implement generateImage() method. And these methods was copied here to resolve this problem. But, actual fix was implementing an empty generateImage() method for base Captcha struct. 2022-06-26 23:57:16 +04:00
Alexander Andreev 8053952122
Captcha implementation was moved off to pkg directory to be able to be used as an external library. 2022-06-26 23:53:52 +04:00

Methods Solve, GetAnswer, IsSolved, and Expiry could be implemented once for a base Captcha struct. But GetImage and generateImage methods should be implemented by all structs that compose with base Captcha struct. 2022-06-26 22:02:38 +04:00
