-- Other tribble contributors did major refactoring / simplification of tribble, which required some changes to GATK code
-- Integrationtests pass without modification, though some very old index files (callable loci beds) were apparently corrupt and no longer tolerated by the newer tribble codebase
-- HMS no longer tries to grab and throw all exceptions. Exceptions are just thrown directly now.
-- Proper error handling is handled by functions in HMS, which are used by ShardTraverser and TreeReducer
-- Better printing of stack traces in WalkerTest
-- Unfortunately the result of the multi-threaded test is non-deterministic so run the test 10x times to see if the right expection is always thrown
-- Now prints the stack trace and exception message of the caught exception of the wrong type, if this occurs
-Running the GATK with the -et NO_ET or -et STDOUT options now
requires a key issued by us. Our reasons for doing this, and the
procedure for our users to request keys, are documented here:
http://www.broadinstitute.org/gsa/wiki/index.php/Phone_home
-A GATK user key is an email address plus a cryptographic signature
signed using our private key, all wrapped in a GZIP container.
User keys are validated using the public key we now distribute with
the GATK. Our private key is kept in a secure location.
-Keys are cryptographically secure in that valid keys definitely
came from us and keys cannot be fabricated, however keys are not
"copy-protected" in any way.
-Includes private, standalone utilities to create a new GATK user key
(GenerateGATKUserKey) and to create a new master public/private key
pair (GenerateKeyPair). Usage of these tools will be documented on
the internal wiki shortly.
-Comprehensive unit/integration tests, including tests to ensure the
continued integrity of the GATK master public/private key pair.
-Generation of new user keys and the new unit/integration tests both
require access to the GATK private key, which can only be read by
members of the group "gsagit".
-- Previously, on the fly indices didn't have dictionary set on the fly, so the GATK would read, add dictionary, and rewrite the index. This is now fixed, so that the on the fly index contains the reference dictionary when first written, avoiding the unnecessary read and write
-- Added a GenomeAnalysisEngine and Walker function called getMasterSequenceDictionary() that fetches the reference sequence dictionary. This can be used conveniently everywhere, and is what's written into the Tribble index
-- Refactored tribble index utilities from RMDTrackBuilder into IndexDictionaryUtils
-- VCFWriter now requires the master sequence dictionary
-- Updated walkers that create VCFWriters to provide the master sequence dictionary
System has the concept of a local and a global MD5 db. The local one is like it operated previously. The global one lives in /humgen/gsa-hpprojects/GATK/data/integrationtests. If the system can find this directory then MD5s will also be read / written to this location. This means that gsabamboo will print differences as appropriate. And all users will in effect have access to a complete history of MD5 file results.
A few minor code reshuffles changed VariantRecalibration and VCFHeader test files.
