There was a problem hiding this comment.
Two nits: space between if and paren.
And using GetArg("-blknotify", "") instead of indexing into mapArgs is probably a good idea for when we add a "getargs" RPC command to dump out the contents of mapArgs (indexing directly into mapArgs will add an empty string to it even if the user never specifies -blknotify at all).
|
On Linux, this leaks a zombie process every time the best block changes, which is probably going to result in PID exhaustion and stuff breaking eventually. Try for example 578e6df in addition. |
|
Good catch. Fixed the most graceful way I could find: by detatching the blocknotify process. I avoided SIGCHLD since it has the potential to not play nice with other stuff. |
