* WriterPool
make new LARGEST_MAX_ACTIVE (255) the capacity of the reuse-pool, so that the maxActive property may vary up to that and still work; also handle more gracefully the failure of trying to use a larger number than the capacity (writer gets closed early rather than left hanging open)
* pom.xml, .classpath
update references to necessary spring-3.0.5 packages
* SeedModule
merge rather than replace event listeners, so that (now later) autowiring doesn't clobber the self-insertion done by anonymous (non-top-level) SurtPrefixedDecideRule bean
* HeritrixLifecycleProcessor, PathScharingContext
use this new non-default LifecycleProcessor to avoid new Spring3 behavior of auto-start()ing context on refresh(build)
* CrawlController
example of using @Value annotation to set default value: will offer benefits for auto-discovery of defaults for configuration interface, or enforcing maximally-explicit configurations (see [HER-1897])
* profile-crawler-beans.cxml, selftest-crawler-beans.cxml
update templates with spring3 preamble/boilerplate
[HER-1910] H3: job-related pages very slow to render (pause mid-way through) in large crawls
* BdbModule
option to reuse bdb data on StoredQueue-creation
* Checkpoint
new saveWriter, loadReader utilities for creating extra checkpoint files (for the long list of ready queues)
* BdbFrontier
on checkpoint, remember ordered list of inProcess/ready/snoozed queues (so same queues are active upon resume)
on resume, reuse old retired/inactive StoredQueue data, and reload active queues from newly-saved list
* StoredQueue
restore tailIndex properly when resuing old data
more-efficient size() calculation (for HER-1910)
* HardLinker.java
makeHardLink() - wrap unix link() and windows CreateHardLink() and choose depending on platform
* BdbModule.java
doCheckpoint() - use HardLinker.makeHardLink()
* GenericReplayCharSequence.java
decode() - read another character to check for more content, rather than consult BufferedReader.ready(), since the latter sometimes returns false even when there is more to read
* ReplayCharSequence, GenericReplayCharSequence
use Charset instance rather than String-name
* Recorder
use Charset instance ratehr than String-name
(getContentReplayCharSequence) avoid reusing cached ReplayCharSequence when encoding-in-use has changed since it was created
(getContentReplayPrefixString) allow requested specific charset-interpretation
* ExtractorHTML, ExtractorXML
work with Charset instances
double-check that in-content-declarations are self-consistent before using
recycle matcher instances
change minor charset problems/decisions to a crawl.log annotation
* ExtractorXML.java
if charset not spec'd in http header look for <?xml encoding=""?>
* ExtractorHTML.java
lookForEncodingInContent() -
1. look for <meta http-equiv="content-type"...>
2. if not found then look for <meta charset="">
3. if not found then <?xml encoding=""...?>
* Recorder.java
setCharacterEncoding() - If new encoding is different from old encoding,
close replayCharSequence and set to null, which will trigger recreation on
next retrieval.
* UriUtils.java
NAIVE_LIKELY_URI_PATTERN - revert change and unpublicize
NAIVE_URI_EXCEPTIONS - add some mimetype strings that came up in testing
isLikelyFalsePositive() - unpublicize
* ExtractorXML.java
XML_URI_EXTRACTOR - do not use NAIVE_LIKELY_URI_PATTERN
shouldExtract() - check for mimetype application/vnd.openxmlformats which is not xml
processXml() - use UriUtils.isLikelyUri()
* ExtractorXML.java
instead of considering only strings that start with http(s):, consider all
strings that match UriUtils.NAIVE_LIKELY_URI_PATTERN (and, as before,
constitute the entirety of the xml tag content or attribute value)
* UriUtils.java
- NAIVE_LIKELY_URI_PATTERN - add quotes to the excluded characters so it
does not eat the closing quote when matching xml attribute values, and
make visibility public for use in ExtractorXML
- isLikelyUri() - refactor false positive check into new method
isLikelyFalsePositive() so that it can be used in ExtractorXML avoiding
redundant check against NAIVE_LIKELY_URI_PATTERN
(specifically, when they're in the query string)
* UURIFactory.java
fixup() - replace \ with / up to the first ? in the url, instead of
anywhere in the url
and update comments
* UURIFactoryTest.java
backslash test
* BdbModule.java
new setting, useHardLinkCheckpoints, default true
doCheckpoint now creates hard-links to active log files from the in-environment checkpoint-dir
doRecover now relinks from checkpoint-dir files, when available, in preference to whatever is already in the env-dir
* pom.xml
bring in JNA for native calls
* CLibrary
wrapper for the link() function
* GZIPMembersInputStream
override OpenJDK7GZIPInputStream.readTrailer to not rely on available() as indicator of end-of-stream
fix membersIterator hasNext() to also not rely on available() as indicator of end-of-stream
* ArchiveReader
change innerHasNext to peek one byte (using mark/reset) rather than rely on available() as indicator of end-of-stream
remove redundant getInputStream accessor in favor of field-name-matching getIn/setIn
* ArchiveReaderFactory, (W)ARCReaderFactory
remove no-longer-necessary RepositionableStream references
use getIn() rather than getInputStream()
[HER-728] Offer replay stream that has been un-chunked (whether because response was HTTP/1.1 or used chunked in HTTP/1.0 against spec)
[HER-1876] Offer HTTP/1.1 option - for chunked transfer-encoding (but not persistent connections)
* FetchHTTP
add 'acceptCompression' and 'useHTTP11' properties, both default false
* Recorder
track whether recorded-input is transfer-encoded (chunked) or content-encoded (gzip etc)
offer alternate replay streams for
(1) raw 'messageBody';
(2) entity (un-chunked if necessary)
(3) content (decompressed if necessary)
always content & GenericReplayCharSequence for CharSequence replays
* GenericReplayCharSequence
always use a stream (rather than random-access buffer)
always decode to prefix buffer first, so short content never touches disk no matter the encoding
* InMemoryReplayCharSequence
deleted; 'Generic' now works similarly for small content and anyway random-access for single-byte-encodings is now rarely possible (given deconding streams)
* RecordingInputStream, RecordingOutputStream
adjust for changed stream names, functionality moved to Recorder
* ReplayCharSequence
use Charset instances rather than names
* ReplayInputStream
add convenience constructor (and tmp-file-destroy) for copying any other inputStream into a seekable ReplayInputStream
* OpenJDK7GZIPInputStream.java, OpenJDK7InflatedInputStream.java
backport the working GZIP implementation from OpenJDK7, with minimal
renames/imports/private-to-protected changes to enable member-at-a-time reading
* GZIPMembersInputStream
base on OpenJDK7 implementation to avoid pre- & post-6u23 codepaths, and 6u23/24 readHeader bug
override readTrailer to set member-end; update comment to reflect end-uncertainty without EOF-per-member-mode
* GZIPMembersInputStreamTest, ARCWriterTest
test tweaks
ensure mark()ing more frequently, when reset to before current position won't be needed
* ArchiveReaderFactory
avoid misinterpreting a "c:" local path as a URI scheme
better logging of caught/recovery-attempted IOException
* GZIPMemberInputStream
handling of previously-unrecognized case in pre-JDK6u23: attempt at read() exhausts inflater with no new bytes available (previous nonzero-length read had not indicated inflater finished)
* 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

ugly hack for whois urls
* SchemeNotInSetDecideRule.java
add whois to list of supported schemes
* WriterPoolProcessor.java
shouldWrite() - we should write successful whois fetches

attempt pre-delete of target filename, warn on failure, for better odds on some filesystems
* ARCWriterTest, WARCWriterTest
ensure timely close of readers/writers in case filenames are reused
restore originally-intended unique target names
* CookieSpecBase
use Guava InternetDomainName public-suffixes to both (1) prevent storing cookie on public-suffix; (2) prevent looking-up cookies for public-suffixes
* BdbCookieStorage
correct checkpoint/relaunch behavior: don't reuse persisted cookies on normal relaunches; do reuse on resume-from-checkpoint
* GZIPMembersInputStream
new workaround class that offers choice of pre/post JDK6u23 behavior and new accessors for finding member boundary offsets

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

update for new ObjectIdentityCache shape
addStats() - use putIfAbsent() to avoid race conditions; move
creation of stats map to constructor to avoid another race condition
* WARCWriter.java
switch back to thread-unsafe data structures for stats since object is used
in one thread at a time according to javadoc
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

ExtractorCSS.java, ExtractorXML.java
do not close ReplayCharSequence
* Arc2Warc, Warc2Arc
adapt to new constructors, settings-object
* MiserOutputStream
stream to monitor position, optionally suppress flushes

calculate processor's totalBytesWritten via position offset changes (as before stats-additions)
delegate record-ID generation
