New in this release:
|
||||
|
||||
* --transfer is now an alias for --transferfile {}.
|
||||
* --sql DBURL uses DBURL as storage for jobs and output. It does not run any jobs so it requires at least one --sqlworker. DBURL must point to a table.
|
||||
|
||||
* --transferfile works like --transfer, but takes an argument like --return. This makes it possible to combine transferring files with multiple input sources: parallel -S server --tf {1} wc {2} {1} ::: * ::: -l -w -c
|
||||
* --sqlworker DBURL gets jobs from DBURL and stores the result back to DBURL.
|
||||
|
||||
* total_jobs() can now be used in {= =}: parallel echo job {#} of '{= $_=total_jobs() =}' ::: {1..50}
|
||||
* --sqlandworker is a shorthand for --sql and --sqlworker.
|
||||
|
||||
* --sqlworker requires the output of a single job to fit in memory.
|
||||
|
||||
* --results now also saves a file called 'seq' containing the sequence number.
|
||||
|
||||
* If $PARALLEL_ENV is a file, then that file will be read into $PARALLEL_ENV.
|
||||
|
||||
* man parallel_tutorial has been given an overhaul.

* A new process B is spawned (by an unrelated process)
|
||||
* This is done during the same I<sleep sleeptime> cycle
|
||||
* B is owned by the same user
|
||||
* B reuses the pid of the A
|
||||
The DBURL must point to a table name. The table will be dropped and
|
||||
created. The reason for not reusing an exising table is that the user
|
||||
may have added more input sources which would require more columns in
|
||||
the table.
|
||||
|
||||
It is considered unlikely to ever happen due to:
|
||||
The table columns are similar to joblog with the addition of B<V1>
|
||||
.. B<Vn> which are values from the input sources, and stdout and
|
||||
stderr which are the output from standard output and standard error,
|
||||
respectively.
|
||||
|
||||
The Signal column has been renamed to _Signal due to Signal being a
|
||||
reserved word in MySQL.
|
||||
|
||||
* The longest I<sleep sleeptime> sleeps is 10 ms
|
||||
* Re-use of a dead pid rarely happens within a few seconds
