All Implemented Interfaces:

Runnable, UpdateTask, EepGet.StatusListener

class PluginUpdateChecker
extends UpdateRunner

Check for an updated version of a plugin. A plugin is a standard .sud file with a 40-byte signature, a 16-byte version, and a .zip file. So we get the current version and update URL for the installed plugin, then fetch the first 56 bytes of the URL, extract the version, and compare. Moved from web/ and turned into an UpdateTask.

Since:

0.7.12

Constructor Detail

PluginUpdateChecker

public PluginUpdateChecker(RouterContext ctx,
                           ConsoleUpdateManager mgr,
                           List<URI> uris,

Method Detail

getID

public String getID()

Description copied from interface: UpdateTask

Valid for plugins

Specified by:

getID in interface UpdateTask

Overrides:

getID in class UpdateRunner

update

protected void update()

Description copied from class: UpdateRunner

Loop through the entire list of update URLs. For each one, first get the version from the first 56 bytes and see if it is newer than what we are running now. If it is, get the whole thing.

Overrides:

update in class UpdateRunner

bytesTransferred

public void bytesTransferred(long alreadyTransferred,
                             int currentWrite,
                             long bytesTransferred,
                             long bytesRemaining,
                             String url)

Description copied from class: UpdateRunner

subclasses should override

Specified by:

bytesTransferred in interface EepGet.StatusListener

Overrides:

bytesTransferred in class UpdateRunner

Parameters:

alreadyTransferred - total of all attempts, not including currentWrite If nonzero on the first call, a partial file of that length was found, _and_ the server supports resume. If zero on a subsequent call after some bytes are transferred (and presumably after an attemptFailed), the server does _not_ support resume and we had to start over. To track _actual_ transfer if the output file could already exist, the listener should keep its own counter, or subtract the initial alreadyTransferred value. And watch out for alreadyTransferred resetting if a resume failed...

currentWrite - since last call to the listener

bytesTransferred - includes headers, retries, redirects, discarded partial downloads, ...

bytesRemaining - on this attempt only, currentWrite already subtracted - or -1 if chunked encoding or server does not return a length

transferComplete

public void transferComplete(long alreadyTransferred,
                             long bytesTransferred,
                             long bytesRemaining,
                             String url,
                             String outputFile,
                             boolean notModified)

Description copied from class: UpdateRunner

Specified by:

transferComplete in interface EepGet.StatusListener

Overrides:

transferComplete in class UpdateRunner

outputFile - null if unknown (output stream constructor)

                           long bytesTransferred,
                           long bytesRemaining,
                           int currentAttempt)

Description copied from class: UpdateRunner
