Revision history for Perl module TaskForest
1.19 Sat Mar 07 2009
o In Log page, successful job should show 'mark Failure' not 'mark Success'.
o Added log_date to website to make Rerun/Mark of a job from a previous
day work as expected
o Changed RESTful service header and docs - added log_date
1.18 Fri Mar 06 2009
All of the changes in this release are related to the website.
o Made sure that if a job file dies after the fork but before ceding
control back to the wrapper, you can at least see its log, if it was run
with run_with_log
o The website now shows the log file for running jobs, not just jobs that
have completed.
o Fixed bug where marking a job as Success was not working after it had
been marked as Failure
o Moved mark and rerun forms to buttons on the status and logs tables
o Changed website to a horizontal layout, so that we have the full window
width for tables
o Fixed a bug so that rerun jobs log files are displayed correctly on the
web site.
o Added 'Cache-Control: Public' HTTP response header to allow Firefox 3 to
cache SSL pages which it does not do by default. This greatly improves
website performance if you're using Firefox 3. Firefox 2 does not
support the Cache-Control response header, so the website will be slower
if you're using SSL and Firefox 2 or earlier.
o Added the 'help' and 'about' documentation sections to the website.
1.17 Sat Feb 21 2009
The major change in this release is the addition of an alternative run
wrapper script called run_with_log. It performs the same functions as the
original wrapper, and also creates a log file that captures both STDOUT
and STDERR of the job being run. On the website you can now display the
log file of any running or completed job, by clicking on the displayed
status of the job. The RESTful web service also supports this. A couple
of entries have also been added to the HOWTO section of the documentation.
1.16 Wed Feb 18 2009
Minor bug fix. An incorrect test job file was shipped in the previous
version. This file relied on /bin/bash, and not /bin/sh. This caused
test 017 to fail on any machine that did not have /bin/bash. The file has
been fixed in this release.
1.15 Sun Feb 15 2009
The ordering of jobs displayed by the status command was changed. The
status command now accepts a --date option, to view jobs that ran on a
previous date. When run for the current day, the status command now also
displays all jobs that ran that are not currently in any Family. This
handles the case where the jobs are removed from family files intra-day,
after running. These jobs are displayed using the newly-supported
default_time_zone option.
This release also introduces taskforestd, a perl-only web server that
implements a RESTful web service that can be used by programatic clients
to access the Taskforest system. The web server also includes a web site
that can be used by humans to interact with Taskforest. The web server
uses Basic Authentication to authenticate the user, so if you wish to use
it outside an intranet, you should use taskforestdssl, the SSL version of
the program.
1.14 Thu Jan 22 2009
A new config option (and command line argument) was added. The
ignore_regex option instructs the system to ignore any Family files whose
names match the regular expressions specified by this option. It's
primarily used to ignore .bak and ~ files left by text editors. Also
fixed a bug so that invalid file names are excluded.
1.13 Mon Jun 02 2008
The behavior of recurring jobs that are scheduled in a foreign time zone
was not well defined. Now, the 'start' and 'until' of recurring jobs are
always based on the most specific timezone of the job.
1.12 Sun Jun 01 2008
A border-condition bug dealing with foreign timezones crossing a date
boundary was fixed.
1.11 Wed May 28 2008
Minor errors in the documentation and logging
were fixed. A test case that was returing
false negatives was made more robust.
1.10 Mon May 26 2008
Syntax error checking was added to the Family
file parser. Optional logging of STDOUT and
STDERR is now possible. The mark and rerun
commands can now act on just the job specified,
or on all its dependents or on both - the job and
its dependents. Finally, a config file can now
be used in lieu of command-line options or
environment variables.
New options are:
--log
--config_file
--chained
--log_threshold
--log_file
--err_file
A sample config file can be found in the main
directory as well as in the pod for TaskForest.
Please see the TaskForest pod for more details:
perldoc TaskForest
OR
man TaskForest
Because of these changes, there are two new
dependencies:
Log::Log4perl version 1.16 or higher
Config::General version 2.38 or higher
1.09 Sun Apr 27 2008
Summary:
Two new scripts were added: 'rerun' schedules
A job to be rerun, and 'mark' marks a
previously job as Success or Failure. A new
'chained' option was added to the definition
of repeat jobs, and a '--collapsed' option was
added to the status script.
Details:
1) The 'rerun' script makes a job available to be
rerun, regardless of whether or not it ran
successfuly. It does this by renaming the
job's log files from FF.JJ.* to
FF.JJ--Orig_n--.* where n is an integer that
starts at 1 for the first rerun, and is
incremented by one at every rerun.
2) The 'mark' job marks a job as 'Success' or
'Failure', regardless of whether or not it ran
successfully. It does this by renaming the job
rc file from FF.JJ.x to FF.JJ.0 (in the case of
Success) or FF.JJ.1 (in the case of Failure).
If the job's status is already as requested, a
warning is printed, and nothing is done.
3) By default, repeat jobs (those that have the
'every' and 'until' options) have only one
dependency - their time dependency. They are
not dependent on each other. In retrospect,
the correct behavior should have been to make
the jobs also dependent on each other.
Consider the case where a job is to run every
hour, but for whatever reason, taskforest does
not run until half-way through the day. This
would cause half of the jobs to run at the same
time at the first opportunity. The new
'chained' option makes the repeat jobs
dependent on each other.
4) Also related to repeat jobs: the new
--collapsed option to the status command
prevents repeat jobs that are in the 'Waiting'
state from being displayed. This is especially
useful when you have a job scheduled to be run
once every minute, and it's only 8:00 a.m. You
probably wouldn't want to see 960 entries when
one would suffice.
1.08 Mon Apr 07 20:52:00 2008
A couple of the files required for the most recent test case was
missing from the distribution. Added those files to the
distribution. No code changes are present in this distribution.
1.07 Sun Apr 06 20:50:00 2008
A major bug was fixed in this release. Long-running jobs (that ran for
longer than the wait time, or longer than the time between two
invocations of taskforest) were not recognized as such. This caused
the jobs to be marked as 'Ready' and not 'Running', causing them to
be run again. All users are urged to upgrade to this release and
make sure to use the current version of the 'run' wrapper.
