So if I use the cache helper, and its set to expire at the default of 15 minutes, I have to type my password in every 15 minutes, even if I am doing a Git operation roughly every 8 minutes during a work day? > We can solve this by marking a credential that comes from a > helper, so we don't bother feeding it back to the helpers. > The credential struct already has an "approved" flag so > that we try to store it only once, rather than for each > successful http request.

I have a helper that generates a password by asking a remote system to generate a short lived password based on other authentication systems that I can't describe. Once I have that password, its good for $X time. The helper just dumps it out to Git, and Git turns around and stores it into the cache for me. This means later requests will keep that credential in the cache, and avoid making that remote system call every time I do a Git network command. I guess I now need to change my helper to cache git credential-cache itself and store the password into the cache if it wants to use the cache? Should we update the credential helper documentation at the same time as this change to make it clear Git won't cache passwords returned from helpers, but a helper could call the credential-cache itself if it wanted to reuse the existing cache service? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
