java - Tomcat: what happens when a HTTP Multipart request gets interrupted? -


from understanding of this, when tomcat server receives http multipart request, servlet invoked after transfer of parts completed.

what happens if transfer gets interrupted in middle? (for example if network connection of client drops while uploading 1gb file?) when servlet invoked in case?

to specific, can see inside servlet not-properly closed java.io.inputstream (from interrupted transfer probably), expect server reject multipart incomplete before invoking servlet? how explain theses not-properly closed files? http protocol has control mechanisms prevent incomplete requests. (i'm using org.apache.commons.fileupload.fileitem apache commons fileupload)

my question might not specific java/tomcat.

it unlikely tomcat in years forgot close multipart streams, although not impossible considering huge amount of bugs. guess somewhere else in application code.

in general if client fails upload multipart stream error on protocol level , has nothing application, server handles it. same if call web address first half entered. handled server, because answer can terminate connection @ point.

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
