20080507: Changed default tail command arguments Fixed input-record-separator command line argument to allow for a null string Corrected perlcode parsing and depth handling Fixed how swatch kills off the tail command on exit Fixed how the tail command is launched 20060721: Took out print statement in Threshold module that was only there for debugging purposes. 20060720: Trying submitted patch no. 1160401 so that tail will die when it is supposed to. Swatch now dies when it cannot write its watcher script instead of chewing up the CPU doing nothing. 20060713: Updated documentation. 20060622: Eliminated the default configuration since it really did not do anything useful. 20060601: Set $0 in the swatch script to the original command line so that it can be distinguished from other swatch instances in the process table. 20060502: Added "include" configuration keyword for including other configuration files into the main one. Fixed handling of variable set by --dump-script command line argument. 20060428: Can now use \ as a line continuation indicator in config file. 20060425: Created Threshold module as an intended replacement for throttle 20060309: Changed setting of SIGCHLD from IGNORE to DEFAULT. Added "normal" mode to echo action for backward compatability Removed passing of unused REGEX option to throttle Fixed setting of $RestartTime variable so that it will restart on the 1st day Fixed parsing of "perlcode 0" caused by code block being incorrectly flagged as being open. 20051201: Fixed documentation errors described in [ swatch-Patches-938132 ] Fixed dependency checking and documentation [ swatch-Patches-983344 ] Added /usr/bin/write as default command to the "write" action. [ swatch-Patches-983347 ] Fixed grammatical and typographical errors as well as an option quoting bug. [ swatch-Patches-986013 ] Fixed MAILER assignment. [ swatch-Patches-1077713 ] 20040719: Released version 3.1.1 20040701: Fixed error in default TIME_REGEX option in throttle function. Added proper signal handling to mail action so that it wont hang on UNIX OSes like FreeBSD. 20040408: Released version 3.1 20031118: Fixed extra module "use" code 20030313: Changed tail arguments from "-1 -f" to "-n 0 -f" 20030109: Put action and throttle code into modules named Swatch::Actions and Swatch::Throttle respectively. Changed "-I" command option from being shorthand for "--input-record-separator" to being short for "--extra-include-dirs" Added --extra-include-dirs (or -I) and --extra-modules (or -M) command line options. 20020712: Changed $PERL setting from 'perl' to $^X Changed interval from 1.0 to 0.5 and added maxinterval setting to File::Tail->new options. Removed commas from string of addresses passed to the mailer in mail action code. 20020429: Fixed message option assignment within and outside of throttle blocks. 20020419: Fixed yet another throttle bug that was causing it to return blank messages. Added depth setting to perlcode to allow perlcode to be placed in different levels of nested blocks. 20020412: Fixed typo in threshold code generation. 20020405: Added '-1' to default arguments for use with tail. 20020403: Added --tail-program-name and --tail-args command line options 20020402: Added "code" action so users can insert perl code in action area Added possibility for user to overide "message" option to any action. Added --awk-field-syntax and --noawk-field-syntax command line options 20020329: Moved write_pid code from the main script to the generated (watcher) script. Added "perlcode" and "threshold" Corrected various typos Allowed watchfor, ignore, throttle, threshold, and perlcode keys in config file to be case insensitive. fixed STDOUT autoflush setting. 20020319: Added option for user to use their own regular expression to extract a throttle key from a message using greedy pattern matching. 20020307: Went back to using the system's tail(1) command for tailing files. Added --use-cpan-file-tail option to users to keep using the File::Tail module for tailing files. Added testing for validity of patterns. 3.0.4: Fixed major bug involving key value assignment in throttle. 3.0.3: Simplified Makefile.PL Fixed action parsing problem where a space was being appended to the option name. Fixed action parsing problem dealing with quotation marks. Fixed documentation on the '--restart-time' command line option. 3.0.2: Changed the default input file to be /var/log/messages instead of /var/log/syslog if it exists. Fixed problem of swatch continuing to try to match a pattern after the pattern was matched but was throttled. Credit goes to Rob Davies for bringing this to my attention. Changed building of throttled messages to replace characters that are cut out with a '_' Added date_loc, time_loc, and extra_cuts options to throttle. Fixed numerous problems with throttling Changed "#!/bin/sh -" to "#!/usr/bin/perl" on first line of script. Fixed "--daemon" mode so that it runs more reliably in the background by: Cleaned up read_config routine. Fixed parsing problem involving the use of a single TAB as a separator. Added default code generation when faced with a config file that does not contain anything useful. Changed format of message displayed when throttling to include the entire message. 3.0.1: Fixed code that searches for sendmail program. 3.0: Fixed write action. Added code to search for sendmail and write programs. Fixed documentation to say that "use=message" is the default for throttle. Added --pid-file option. Removed --pattern-separator and --action-separator options from documentation. Changed record structure that holds configuration information so that it can handle multiple actions of the same type within a single watchfor block. Turned autoflush on inside of pipe action. 3.0b5: Implemented use of $n (field number variable) use in commands. Added the "keep_open" option to the "pipe" action. The pipe is now closed every time the action is used unless this option is used. Added the "use" option to throtle. 3.0b4: Removed "use strict;" from watcher script until I make the code a little cleaner. It currently prevents the "--examine" switch from working. 3.0b3: Added "continue" and "quit" actions. Changed keyword/value separation from '=' to whitespace, but will still handle the '=' sign for backward compatability. This was done in order to make the configuration file make more sense. Reverted back to creating a script file, but instead of creating it in /tmp, Swatch creates it in the user's home directory under the name .swatch_script.<PID> Fixed parsing of "throttle" setting. Added "when" option to all actions to allow for time-of-day and day-of-week specific actions. Added "subject" option to "mail" action. 3.0b2: Added signal handling. Updated POD to include the color options to the echo action. Fixed sun terminal detection bug in ring_bell subroutine. Fixed echo() subroutine to handle multiple modes. Added some color definitions for use in echo() routine. Corrected errors in example files. Fixed package checking code in Makefile.PL and added some perl version checking.
