amazon web services - CI/CD process with Jenkins or Chef -


suppose have following jobs: 1: detect there new war file on s3. 2: pull s3 bucket. 3: stop wildfly server 4: replace war file on wildfly server 5: restart wildfly server enter image description here

the diagram using jenkins example. wildfly , appeon on ec2 instance. because of licensing issue, can't use cft create new instance every time, have assume these steps done within ec2 instance.

let's assume failover not issue.

two routes done, 1 using jenkins, jenkins watch s3 bucket, , stop, replace, restart server , war, without creating new instance every time.

the other using chef on instance, check s3 bucket every 5 minutes, example, if there new war file, pull down. (suppose war file name doesn't change...), using magic script stop server, replace war file, restart server, run on same instance.

since don't know ci/cd, jenkins, or chef.

so advice or example help! in advance!

if you're doing, chef waaaaaay overkill. simple bash script run cron (or systemd timer unit if want super fancy) fine. start small , try not overcomplicate things, more moving pieces in deployment pipeline, more things can potentially break (usually @ worst time).

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
