Did some more exploration and perf tuning and thinking on caching
|
|
databases, and am pretty sure I know how I want to implement it. Will be
|
|
several stages, starting with using it for generating views, and ending(?)
|
|
with using it for direct mode file mappings.
|
|
|
|
Not sure I'm ready to dive into that yet, so instead spent the rest of the
|
|
day working on small bugfixes and improvemnts. Only two significant ones..
|
|
|
|
Made the webapp use a constant time string comparison (from `securemem`)
|
|
to check its auth token is valid. Could avoid a potential timing attack to
|
|
guess the auth token, although that is theoretical. Just best practice to
|
|
do this.
|
|
|
|
Seems that openssh 6.5p1 had another hidden surprise (in addition to
|
|
its now-fixed bug in handing hostnames in `.ssh/config`) -- it broke
|
|
the method git-annex was using for stopping a cached ssh connection,
|
|
which led to some timeouts for failing DNS lookups. If you see git-annex
|
|
seeming to stall for a few seconds at startup/shutdown, that's maybe why
|
|
(--debug will tell for sure). Seem to have found a workaround that avoids
|
|
the problem.
