#TODO:
|
||||
|
||||
* First do the pulls then the pushes.
|
||||
If pull prevents the push, the push queue just creates a backlog until it gets a chance to push.
|
||||
|
||||
* When doing a first-pull, there's a safety mechanism for the timeout and detecting duplicate attempts.
|
||||
|
||||
1. Perform all JSON pulls on the source servers.
|
||||
2. Combine the results into one giant pool of URLs.
|
||||
3. Write this pool to a file (TODO-file).
|
||||
4. Shuffle the pool in RAM.
|
||||
5. Start threads for crawling.
|
||||
6. Every finished crawl attempt (successful or not) should write to a 2nd file (DONE-file).
|
||||
|
||||
IF the first-pull times out, don't do anything else.
|
||||
Otherwise, mark the dates we last performed a pull from each server.
|
||||
|
||||
* When resuming a first-pull.
|
||||
|
||||
1. Check for the TODO-file and the DONE-file.
|
||||
2. Remove the entries in the DONE-file from the pool in the TODO-file.
|
||||
3. Replace the TODO-file with the updated pool.
|
||||
4. Perform steps 4, 5 and 6 (shuffle, create threads and crawl) from before.
|
||||
|
||||
This way you can resume without repeating attempts.
|
||||
|
||||
* Write documentation about syncing.
|
||||
|
||||
* Create "official" directory policy for my directory.
|
||||
|
||||
* Decide if a retry mechanism is desirable for pulling (for the failed attempts).
|
||||
After all, you did imply trust when you indicated to pull from that source...
|
||||
This could be done easily by doing a /sync/pull/all again from those sources.
|
||||
|
||||
* Decide if cron_sync.php should be split into push pull and pull-all commands.
