when we set two path using evhtp_set_cb like below，it will math wrong cb：
path1: /abc/0 cb1
path2：/abc/012 cb2

when we call the rest server using path /abc/012 ,it will call cb1

It also searches in an ordered manner; have you tried putting the longest match first?

yeah，I tried, it works. but I'm a low-level component, and the real user is someone else, and I can't ask them to use it like this. I need to find a way to circumvent this problem, or our upper-level code needs to be changed.

I see. Any auto-sort would only apply to static URI's, I cannot sort based on regex or globs for obvious reasons. Is that OK?

Hello @lwzcwh,

I pushed up a test branch for you here: https://github.com/criticalstack/libevhtp/tree/issue129 (diff here: https://github.com/criticalstack/libevhtp/compare/issue129)

I am leaving this as an optional compile-time flag, you must run cmake with the following:

cmake -DEVHTP_SORT_CALLBACKS=ON ..

..along with any other options you would like.

Since I do not want to affect any other code, this is not enabled by default. If this looks OK to you, I will merge.
