问题 All the methods of std::sync::atomic::AtomicBool take a memory ordering (Relaxed, Release, Acquire, AcqRel, and SeqCst), which I have not used before. Under what circumstances should these values be used? The documentation uses confusing “load” and “store” terms which I don’t really understand. For example: A producer thread mutates some state held by a Mutex, then calls AtomicBool:: compare_and_swap(false, true, ordering) (to coalesce invalidations), and if it swapped, posts an “invalidate”

问题 I have two arrays, old and new, which hold objects at each position. How would I sync or find the delta (i.e. what is new, updated and deleted from the new array compared to the old array) var o = [ {id:1, title:"title 1", type:"foo"}, {id:2, title:"title 2", type:"foo"}, {id:3, title:"title 3", type:"foo"} ]; var n = [ {id:1, title:"title 1", type:"foo"}, {id:2, title:"title updated", type:"foo"}, {id:4, title:"title 4", type:"foo"} ]; With the above data, using id as the key, we'd find that

问题 Consider the following simple entity model: Entity A has a to-one relationship to Entity B called b . Entity B has an inverse to-one relationship called a . Neither relationship is optional. A B b < ----- > a Assume we have two devices (1) and (2) that begin fully synced. Each has one object of class A, and one object of class B, and they are associated with one another. On device 1, we have objects A1 and B1, and on device B we have the same logical objects A1 and B1. Now assume that

问题 I have a large MySQL database, lets call it live_db , which I want to replicate on the same machine to provide a test system to play around with ( test_db ), including table structure and data. In regular intervals I want to update the test_db with the content of the live_db ; if possible incremental. Is there some built-in mechanism in MySQL to do that? I think that master-slave replication is not the thing I want since it should be possible to alter data in the test_db . These changes do

问题 I've made a Chrome extension with an options page. The data is saved in localstorage and works just fine. Chrome doesn't sync the localstorage to the cloud, just the extensions.

I can not find an API at http://developer.chrome.com/extensions/docs.html which allows me to sync the user-chosen preferences. What methods do you suggest? 回答1: In the (hopefully near) future, you'll be You are now able to store

I guess I am asking, how do I dump all of my data in my tables into my PHP script, so that it can update and insert the data into another database on the server? I have no clue where to even begin with this. 回答1: The terminology in this question is a little confusing. If you're trying to copy the

问题 Sorry for the long and confused title. I have a customer that wants to sync three database. (Later it could be more.) All data in all three databases must sync to the all others. This does not at all need to be real time but would probably run nightly or something like that. This database is using identity columns as primary/foreign keys. The issue is that a given record could be added independently into two (or even more) of the databases but be the same data. So, for example, I could have a
