kdb-common-1.1.0-rtm.1

This release includes the following changes to the following libraries - log, tz, ns and cron.

Logging (log)

• The logger has been made ~10% more performant (within .log.msg)
• The library now supports multiple loggers within the .log.loggers namespace and configured within .log.cfg.loggers
• Two additional loggers are provided:
  • -logSyslog: syslog style logging for use with journald
  • -logJson: JSON logging for use with log capture applications

Timezone Conversion (tz)

A new timezone conversion library has been added, based on the code described at https://code.kx.com/v2/kb/timezones/.

Namespace Management (ns)

• .ns.protectedExecute - now supports returning the stacktrace if function errors (see below)
• .ns.getFunctionArguments - now throws IllegalArgumentException if the object passed is not a function (or function reference)

.ns.protectedExecute

This function has been updated to support returning the stacktrace when a function execution fails - see the ns.q wiki page for more information.

In version kdb-common-1.0.4-rtm.1 and earlier, this function returned a list of (isError; errorMsg). It now returns a dictionary. However the order of the dictionary has been maintained such that running first and last will return isError and errorMsg respectively.

Cron Timer (cron)

Support for capturing the stacktrace output from .ns.protectedExecute when a timer function fails was added. However, this has added some non-upward compatible changes:

.cron.cfg.jobId (NUC)

This variable has been renamed to .cron.jobId

.cron.status (NUC)

• The first row of the table is now an empty row with a generic null element for the result column
• The results are no longer enlisted before being added to the table
• The result when success is 0b is now a dictionary (based on the related changes to .ns.protectedExecute)
