* TextSeedModule
refactor announceSeeds to occur in background thread if non-default blockAwaitingSeedLines value is set
signal CountDownLatch on each line, allowing calling thread to proceed at right count
* profile-crawler-beans.cxml
commented-out blockAwaitingSeedLines default settings (-1, meaning wait for all seed lines)
* CrawlController
change pauseAtFinish to runWhileEmpty
add EMPTY state
replace isStateRunning() with isActive() (RUNNING or EMPTY)
trigger finish-test off frontier EMPTY rather than PAUSE
in logging say 'running' rather than 'resumed'
* Frontier
add EMPTY state
* AbstractFrontier
handle EMPTY like RUNNING, transition EMPTY<->RUNNING when appropriate
* StatisticsTracker
handle EMPTY analogous to RUNNING
in logging say 'running' rather than 'resumed'
* CrawlJob, DiskSpaceMonitor
replace isStateRunning() with isActive()
redirect url sometimes '0 NOTCRAWLED' in seeds-report.txt even when crawled"
* CandidatesProcessor.java
innerProcess() - set force-fetch on outlinks promoted to seeds
* CrawlURI.java
new field JSONObject extraInfo, methods getExtraInfo() and addExtraInfo()
* WARCWriterProcessor.java
write() - on success, add warcFilename to CrawlURI extraInfo
* CrawlerLoggerModule.java
new config option logExtraInfo, default false
* UriProcessingFormatter.java
new field logExtraInfo
format() - include CrawlURI extraInfo if logExtraInfo is enabled
also include "-" if CrawlURI has no annotations, since this is no longer the last field on the line
* profile-crawler-beans.cxml
<!-- <property name="logExtraInfo" value="false" /> -->
* NonFatalErrorFormatter.java, RuntimeErrorFormatter.java
new constructor to handle logExtraInfo since these subclass UriProcessingFormatter
even when crawled, when original seed also has a regular link to the redirect
url
* CandidatesProcessor.java
innerProcess() - present seed outlinks to the frontier ahead of non-seed outlinks, so that seed version of any duplicated outlink is always the one that's crawled
* FetchHTTP.java
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
by default - this is what my firefox 4.0 for mac sends
* profile-crawler-beans.cxml
commented-out default value
marshalDocument() - SAXException can wrap other exceptions, e.g.
EOFException when tcp connection is broken; thus, in case of IOException,
rather than throwing a RuntimeException, re-throw the wrapped IOException
(unfortunately in that case we still get a massive stack trace in the log,
but at least it comes from the appropriate spot and is not too misleading)
* URIAuthorityBasedQueueAssignmentPolicy.java
whois urls all go in special "whois" queue
* PreconditionEnforcer.java, CrawlURI.java
move markPrerequisite() method from PreconditionEnforcer to CrawlURI
* profile-crawler-beans.cxml
commented-out whois fetcher clause
* FetchStatusCodes.java
new status codes for whois
* ServerCache.java
getHostFor() - return "whois:" for whois urls, following dns: convention
* UURIFactory.java
ugly hack for whois urls
* SchemeNotInSetDecideRule.java
add whois to list of supported schemes
* WriterPoolProcessor.java
shouldWrite() - we should write successful whois fetches
* WARCWriterProcessor.java
write whois records
* FetchWhois.java
the fetcher
use heritrix.home, if available, to find default logging.properties (to let those who launch Heritrix from elsewhere save themselves from HttpClient's copious logging)
* StatisticsTracker
move small stat maps to in-memory ConcurrentMaps
update processedSeedRecords for new ObjectIdentityCache shape
move hostsDistribution/hostsBytes/hostsLastFinished tracking to CrawlHosts/hostsCache
* CrawlSummaryReport
gets hosts count from hostsCache
* SeedRecord
implement IdentityCacheable
* FetchStats
remember last-success times
* IdentityCacheable
new interface required of objects stored in ObjectIdentityCaches
* IdentityCacheableWrapper
wrapper for storing arbitrary objects in ObjectIdentityCaches
* ObjectIdentityCache
keys now always Strings
values now always IdentityCacheables
new dirtyKey() method to ensure a key is persisted
* ObjectIdentityBdbCache, ObjectIdentityMemCache
update for new ObjectIdentityCache shape; still using legacy GC magic
* ObjectIdentityBdbManualCache
alternate implementation relying on dirtying to ensure persistence
use Guava library MapMaker for soft memMap; capped dirtyMap
* BdbModule
use ObjectIdentityBdbManualCache by default
up expectedConcurrency default to 64
* BdbModuleTest, ObjectIdentityBdbCacheTest, ObjectIdentityBdbManualCacheTest
update, add tests
* Frontier
FrontierGroup as IdentityCacheable
* AbstractFrontier, WorkQueueFrontier, BdbFrontier
touchup queue/group accessors
make queue instances dirty whenever mutated
* WorkQueue, CrawlHost, CrawlServer
IdentityCacheable support; appropriate makeDirty()s
* ServerCache, DefaultServerCache
update for new ObjectIdentityCache shape
* CrawlURI
MAX_HOPS_DISPLAYED constant, 50
build new CrawlURI pathFromSeed value via extendHopsPath, which shows only MAX_HOPS_DISPLAYED hops, and precedes string with int value of hops unshown
* CrawlURITest
test for extendHopsPath
processing is finished.
* Recorder.java
getReplayCharSequence() - remember ReplayCharSequence, obtain new one if
none remembered or remembered has been closed
endReplays() - close replayCharSequence
* ToeThread.java
run() - call Recorder.endReplays() when finished with uri
* ReplayCharSequence.java
isOpen() - return false if close() has been called
* GenericReplayCharSequence.java, InMemoryReplayCharSequence.java
implement isOpen()
* KeyWordProcessor.java, ExtractorHTML.java, HTTPContentDigest.java,
ExtractorCSS.java, ExtractorXML.java
do not close ReplayCharSequence
* WorkQueue.java
add noteExhausted() for emptied queues
* WorkQueueFrontier.java
add synchronization around checkFutures() activity
use noteExhausted when queue is totally empty
* DecideRuleSequence.java
- use Spring Lifecycle start() to initialize logToFile
- inject logger module as SimpleFileLoggerProvider, since we're in
heritrix-modules and don't have access to CrawlerLoggerModule from
heritrix-engine
* CrawlerLoggerModule.java
- implement SimpleFileLoggerProvider
- setupSimpleLog() - use 'T' instead of '+' between date and time in
timestamp
* SimpleFileLoggerProvider.java
new interface with one method, setupSimpleLog()
* Scoper.java
do not call scope.start()/scope.stop(), these are handled using Spring
Lifecycle now
* DecideRule.java
remove unused, unneeded start()/stop()
* KryoBinding.java
always default to registrationOptional, for now
* StatisticsTracker.java
explicitly set valueClass of sourceDistribution to ConcurrentHashMap
* StoredQueue.java
answer 0 for size() when backing DB closed
