* .classpath, pom.xml, org/apache/commons/pool/impl/*
remove references to and patched classes based on commons-pool
* WriterPool.java
move instance creation/round-robin-pool/dispose into this class
close (rather then recycle) extra writers when crawl slows (via tracking time of last need/rollover)
* WriterPoolMember.java
add isOversize() for external check of ready-to-rollover file
avoid rollover before every record (so that set of related WARC records aren't split between files)
* ARCWriterPool.java, WARCWriterPool.java
remove BasePoolableObjectFactory reference, implement class-appropriate makeWriter()
* ARCWriterPoolTest.java
adjust for new never-timeout behavior
* ARCWriterPoolProcessor.java WARCWriterPoolProcessor.java
adjust constructor calls
* WriterPoolProcessor.java
replace poolMaxWaitMs (which caused eventual complete timeout from waiting for writer) with maxWaitForIdleMs, a much smaller value which only controls how long a thread waits for an reusable writer before considering creating a new one. (If creation isn't allowed, threads will now wait indefinitely for a writer to become available.)
* Heritrix.java
make heritrix.hostname, heritrix.pid, heritrix.port available as global properties
* PropertyUtils.java, PropertyUtilsTest.java
utility methods to interpolate string values from one or several supplied Properties instances
* ArchiveUtils.java
utility methods to give timestamps guaranteed larger/different than any previously-issued timestamp
* WriterPoolSettings.java, WriterPool.java, ARCWriterPool.java, WARCWriterPool.java, ARCWriterPoolTest.java
improve field names, change 'suffix' to more general 'template'
* WriterPoolMember.java
replace 'suffix' with 'template' which is interpolated when specific name is needed
set default template to pattern extremely unlikely to generate duplicate filenames
change default prefix to 'WEB'
centralize creation of new basenames into generateNewBasename() method, which internalizes timetamp/serialNo minting and interpolation
* WriterPoolProcessor.java, ARCWriterProcessor.java, WARCWriterProcessor.java
serve as own WriterPoolSettings instance
replace 'suffix' with 'template'
* ARCWriter.java
accept (but truncate) 17-digit timestamps at creation
* DefaultWriterPoolSettings.java, TimestampSerialNo.java
delete as superfluous
* ExtractorHTTP.java
add property inferRootPage; if true (not the default), always consider '/' inferred from all HTTP(S) URIs
* Hop.java, LinkContext.java
add new hop-type 'I' for inferred URIs; add corresponding LinkContext
* ExtractorImpliedURI.java
use new 'I'nferred types
* CrawlURI.java
improve comments for fetchAttempts methods
(resetForRescheduling) added to clear per-scheduling state
* WorkQueueFrontier.java
call resetForRescheduling just before scheduling-at-specific-time
* FrontierJournal.java, AbstractFrontier.java
renamings: prefer 'reenqueue' instead of 'reschedule' for describing simple (non-timed) retries
* ExtractorHTML.java
smaller caps on element-name, attribute-name, attribute-value lengths -- costly match-failures on bad/non-HTML may be eating a lot of cycles
* ReplayCharSequence.java, GenericReplayCharSequence.java, InMemoryReplayCharSequence.java
store actual first exception for reference
* ExtractorHTML.java
report exception in nonfatal-log, rather than WARNING (which was still polluting job log more than desired -- but should still be logged to allow future investigation of sites where encoding issues may exist)
* ReplayCharSequence.java
new interface method: getDecoderExceptionCount(), reporting >0 if any decoding problems were encountered and silently replaced
* GenericReplayCharSequence.java
count decoding problems, and only log as FINE rather than WARNING
* InMemoryReplayCharSequence.java
try decoding with reporting; if any problems note at least one then decode without reporting errors
* ExtractorHTML.java
after using ReplayCharSequence, log WARNING if nonzero decoding errors
* GenericReplayCharSequence.java
* Scoper.java
* FetchFTP.java
* FetchHTTP.java
demote a bunch of INFO logging to FINE so that be default, console isn't filled with output for every URI handled by a busy crawl
* UriUtils.java
move likely-URI heuristics here for better consistency, reuse, testing, improvement
* UriUtilsTest.java
testing for UriUtils
* ExtractorJS.java
move likely-URI support to UriUtils; use new test
* ExtractoSWF.java
use new UriUtils likely-URI testing
* ExtractorHTML.java
move likely-URI testing to UriUtils, use new test
* JerichoExtractorHTML.java
use new UriUtils likely-URI testing
* CrawlServer.java
enable a specific kind of connect-lost (no response given) to be counted as 'deemed 404' on robots retries over a minimum
* FetchStatusCodes.java
add a synthetic code: -404, S_DEEMED_NOT_FOUND
* FetchHTTP.java
better distinguish CONNECT_FAILED and CONNECT_LOST
* DispositionProcessor.java
treat CONNECT_LOST same as _FAILED; simplify a test
* PersistProcessor.java
rename setupEnvironment to setupCopyEnvironment to make limited purpose of env clear; catch and rethrow IllegalArgumentException with hint that second-open may be cause
* PersistLoadProcessor.java
catch and display IllegalArgumentException same as other failure-to-open SEVERE but proceedable exceptions
* PrecedenceLoader.java
update method names
* EnhancedEnvironment.java
in getClassCatalog(), when read-only env, insist on read-only catalog
* PersistLoadProcessor.java
remove existing curi members from prior to prevent clobbering source
* PersistProcessor.java
set historyDbConfig read-only, set je.log.faultReadSize for
compatability with BDBModule.setup()
* **/pom.xml
bump version identifiers to "3.1.1-SNAPSHOT" (odd minor number meaning dev version, odd patch number indicating expected next patch number of 3.0.x release if before a 3.2.0 release)
* WriterPoolProcessor.java
change description of WriterPoolProcessor.directory ConfigPath to not imply as strongly that is where writing much be occurring
* UURIFactoryTest.java
specify stirng literal with escape-encoding, rather than as raw UTF-8
* **/pom.xml
include 'project.build.sourceEncoding' property to suppress platform-encoding warnings
(unfortunately, neither this nor similar 'maven.compile.encoding' property actually casues maven build to interpret Java source as UTF-8)
offer html
* XmlMarshaller.java
new class to write xml based on nested map structure
* BeanBrowseResource.java ScriptResource.java EngineResource.java
JobResource.java JobRelatedResource.java
support xml representation
* WorkQueueFrontier.java PrecedenceProvider.java WorkQueue.java ToeThread.java
ToePool.java CrawlJob.java Engine.java Frontier.java CrawlController.java
StatisticsTracker.java CrawledBytesHistotable.java FetchStats.java
ProcessorChain.java CrawlURI.java Reporter.java
offer same data that is returned in the single line reports in a map
suitable for use with XmlMarshaller
* FileUtils.java
new method tryToCanonicalize(File)
* AbstractFrontier.java, WorkQueueFrontier.java, BdbFrontier.java
add 'futureUris' map of CrawlURIs to be reenqueued at specific future dates
the usual findEligibleUri also checks for newly-eligible rescheduled URIs
the frontier is no longer empty unless the future count is also 0
* CrawlURI.java
add rescheduleTime property
* ReschedulingProcessor.java
optional post-processor to set a CrawlURI's reschedulingTime
* CrawlStatSnapshot.java, CrawlJob.java
add futureUriCount to stats/uriTotalsReport
* PersistLogProcessor.java
rotate logs on checkpoint
* CrawlerJournal.java, FrontierJournal.java
rotate for checkpoint support without full Checkpointable
processor-related bean checkpoint support:
* Processor.java
implement Checkpointable and BeanNameAware; methods to support JSON state-saving
* DispositionChain.java
implement Checkpointable and during-checkpoint disposition-lockout for state stability
processor-related bean checkpoint support:
* Processor.java
implement Checkpointable and BeanNameAware; methods to support JSON state-saving
* DispositionChain.java

roll log on checkpoint
* TextSeedModule.java, SeedModule.java
eliminate obsolete (and probably unnecessary) checkpoint support
* (others)
adapt to above changes
* IoUtils.java
remove class that confusingly-overlaps with commons IOUtils; move remaining methods to ArchiveUtils or archive's FileUtils
* ArchiveUtils.java, FileUtils.java
receive relocated methods; eliminated deprecated or unused methods
* JSONUtils.java
new class to collect common JSON actions
* Iteratorable.java
wrap Iterator as Iterable for foreach usage
* (many)
