This has implications for both Qscript authors and CommandLineFunction authors.
Qscript authors:
You no longer need to (and in fact must not) manually escape String values to
avoid interpretation by the shell when setting up Walker parameters. Queue will
safely escape all of your Strings for you so that they'll be interpreted literally. Eg.,
Old way:
filterSNPs.filterExpression = List("\"QD<2.0\"", "\"MQ<40.0\"", "\"HaplotypeScore>13.0\"")
New way:
filterSNPs.filterExpression = List("QD<2.0", "MQ<40.0", "HaplotypeScore>13.0")
CommandLineFunction authors:
If you're writing a one-off CommandLineFunction in a Qscript and don't really
care about quoting issues, just keep doing things the direct, simple way:
def commandLine = "cat %s | grep -v \"#\" > %s".format(files, out)
If you're writing a CommandLineFunction that will become part of Queue and
will be used by other QScripts, however, it's advisable to do things the
newer, safer way, ie.:
When you construct your commandLine, you should do so ONLY using the API methods
required(), optional(), conditional(), and repeat(). These will manage quoting
and whitespace separation for you, so you shouldn't insert quotes/extraneous
whitespace in your Strings. By default you get both (quoting and whitespace
separation), but you can disable either of these via parameters. Eg.,
override def commandLine = super.commandLine +
required("eff") +
conditional(verbose, "-v") +
optional("-c", config) +
required("-i", "vcf") +
required("-o", "vcf") +
required(genomeVersion) +
required(inVcf) +
required(">", escape=false) + // This will be shell-interpreted
required(outVcf)
I've ported the Picard/Samtools/SnpEff CommandLineFunction classes to the new
system, so you'll get free shell escaping when you use those in Qscripts just
like with walkers.
Moved gsalib and queueJobReport.R to embeddable namespaced locations.
Updated packager dependencies/dir to add an @includes which filters the embedded fileset.
RScriptExecutor can now JIT compiles the gsalib.
RScriptExecutor uses ProcessController and sends the Rscript output to java's stdout when run under -l DEBUG.
Refactored ProcessController and IOUtils from Queue to Sting Utils.
Added more unit tests to ProcessController along with a utility class to hard stop OutputStreams at a specified byte count.
Replaced uses of some IOUtils with Apache Commons IO.
ShellJobRunner refactored to use direct ProcessController and now kills jobs on shutdown.
Better QGraph responsiveness on shutdown by using Object.wait() instead of Thread.sleep().
