The wrapper.filter pair of properties make it possibleto filter the output of a JVM and then perform some action whenever aspecific trigger string is found. The filtering process works bycomparing JVM console output against registered triggers until a matchis found. At that point the associated action is executed. Only thefirst matching trigger will be handled for any line of output.

It possible to specify an action to take for any exitcode by making use of the wrapper.on_exit.defaultproperty and setting it to either SHUTDOWN or RESTART.The default on_exit property defaults to SHUTDOWN.
curses.start_color (called by curses.wrapper) initializes 8 basic colors, so one would assume you can just use curses.color_pair(i) to display colors. However, curses does not only have colors, it also has color_pairs, and only the later can be used to display color, but start_color only initializes colors, and use_default_colors only initializes color number -1.
If you struggle with no colors displayed after calling wrapper or start_color and use_default_colors, you might be missing the fact that you have to set up color pairs with init_pair before drawing in color.
The class, UserDict acts as a wrapper around dictionary objects.The need for this class has been partially supplanted by the ability tosubclass directly from dict; however, this class can be easierto work with because the underlying dictionary is accessible as anattribute.
This class acts as a wrapper around list objects. It is a useful base classfor your own list-like classes which can inherit from them and overrideexisting methods or add new ones. In this way, one can add new behaviors tolists.
The class, UserString acts as a wrapper around string objects.The need for this class has been partially supplanted by the ability tosubclass directly from str; however, this class can be easierto work with because the underlying string is accessible as anattribute.
Messages may be issued from the Python CoolProp wrapper via the Python warnings module. This module allowsnon-fatal warning messages to be issued to the calling program and stdout to warn ofimproper function usage or deprecation of features. These warnings will, bydefault, be issued each and every time a suspect call is made to CoolProp. While, the bestsolution is to correct the calling code according to the message received, sometimes this isdifficult to do in a legacy or third party code and can result in many, many warning messages that obscurethe output and hinder debugging.
Add wrapper.check_certificate.default.loglevel property to control the log level of non-critical errors detected when performing trust verification on the certificate chain built by the Wrapper. Change the default log level to DEBUG.
Fix incorrect calculation of the offset when using a timezone with 'UTC' format if minutes where specified. The detailed timestamps printed with wrapper.timezone.debug_timestamps, which showed the offset of the system time on Windows, are also corrected.
Fix high CPU usage observed on certain Unix platforms when running as a console application. The Windows platform, as well as daemon installations on Unix are not affected. Since 3.5.47. Applications using version 3.5.48 that do not need to handle stdin may circumvent the issue by adding wrapper.disable_console_input=TRUE to their configuration file. This workaround is not recommended for 3.5.47 because of another issue (see below).
Fix a critical bug on UNIX where the Wrapper could get stuck and fail to restart if a JVM restart was requested by the JVM or Wrapper. This would happen when wrapper.disable_console_input was set to TRUE, which is the default when running as a daemon. Since 3.5.47.
Solaris SPARC releases that were removed in versions 3.5.46 and 3.5.47 are available again. The binaries are now built on Solaris 10 (previously Solaris 9). Note that this architecture was added a few weeks after the release of 3.5.48, which means it is not included in the Delta Pack. It is possible to manually add the binaries to the bin and lib folders of the Delta Pack after renaming them as follows: wrapper-solaris-sparc-64 (or wrapper-solaris-sparc-32) for the executable, and libwrapper-solaris-x86-64.so (or libwrapper-solaris-x86-32.so) for the native library. The Wrapper will load them correctly when executing on a SPARC machine. The SPARC binaries will be included in the Delta Pack on future releases.
Add new property wrapper.java.timezone to make it possible to override the value of wrapper.timezone and configure a different timezone for the Java application. Also add the 'SYSTEM' value to let these properties be set with the local timezone of the system.
Fix a warning message on UNIX platforms where the Wrapper would report that an event command exited unexpectedly if wrapper.event..command.block.timeout was 0. The command would otherwise complete correctly. Positive timeouts were working correctly.
On Windows, automatically switch to monitoring the Java process when it is redirected from the process launched by the Wrapper. Use wrapper.java.monitor=LAUNCHED to restore the previous behavior and monitor the launched process instead.
Fix a parsing error causing the Wrapper to hang on startup if the file 'etcetera' (part of the IANA tz database) was present at the location specified by wrapper.timezone.folder. Removing this file would solve the issue.
Modify the DemoApp so its internal Wrapper instance no longer logs to the main wrapper.log file as that was causing confusion. Fix an NPE in the DemoApp if the Wrapper was shutdown external to the DemoApp dialog.
Add a log message when a wildcard classpath, defined with a wrapper.java.classpath. property, does not match any files. The log level is controlled with the wrapper.java.classpath.missing.loglevel property.
Add property wrapper.ntservice.account.logon_as_service to control whether or not the Wrapper should add the 'Log on as a service' privilege to the configured account during installation of the Windows Service.
Fix issue where the authentication attempt performed during installation of a Windows Service would fail if the configured wrapper.ntservice.account did not have the 'Log on as a service' privilege. Since 3.5.42.
Fix bug where calls to WrapperManager.signalStarting() were overriding the disabling of wrapper.startup.timeout (when its value is set to 0). This was also happening with WrapperManager.signalStopping() and wrapper.shutdown.timeout=0.
Add new property wrapper.console.quickedit to enable or disable the QuickEdit Mode of the console attached to the Wrapper process. The default value will disable the QuickEdit Mode as it can cause the Java application to freeze.
Fix output issues when the Wrapper is elevated to control a Windows Service: - if wrapper.console.direct is set to TRUE (default), force using only stdout to preserve the output order. - if wrapper.console.direct is set to FALSE, handle stdout and stderr separately (previously everything was redirected to stdout). - no longer block when messages are too large.
Add new properties wrapper.monitor_exit and wrapper.java.monitor_exit, which are used by the --setup (-su) command on Windows to allow the Event Log to monitor the Wrapper or Java processes whenever they exit. This is useful to diagnose cases where the Wrapper or Java are being killed by another process.
Fix cases where the Java version was not resolved to its default value if it couldn't be retrieved from the JVM output (for example when wrapper.java.version.timeout elapsed). This was causing the Wrapper to stop.
Ignore wrapper.java.additional.auto_bits and wrapper.java.additional.auto_bits. for Java 9 and above. This means that the "-d32" or "-d64" options will no longer be added to the Java command line. These options were deprecated in Java 9 and their usage started to cause a fatal exception after being removed in Java 10.
Fix an issue where threads were not safely used on HPUX (Itanium and PA-RISC), and inside libwrapper.so (Linux and FreeBSD). For instance, this was causing repeated log errors when the Java IO thread (wrapper.javaio.use_thread=TRUE) was reading no byte from the pipe.
Deprecate wrapper.max_hostid_timeout in favour of wrapper.wait_for_hostid.timeout, and change the default value to 15 which is the maximum number of seconds that the Wrapper should wait for Network Interfaces to come up. Previously the default value was 0 to wait indefinitely.
Add new property wrapper.wait_for_hostid.strict to force waiting for a specific HostId up to the value of wrapper.wait_for_hostid.timeout. The default value if FALSE which tells the wrapper to stop waiting once at least one network interface is found.
Fix an issue where WRAPPER_JAVA_VERSION, WRAPPER_JAVA_VERSION_MAJOR, WRAPPER_JAVA_VERSION_MINOR, WRAPPER_JAVA_VERSION_REVISION were not set if the Java version failed to be parsed and was resolved to the value of wrapper.java.version.fallback or the minimum supported version.
Fix a bug where the Wrapper considered that the wrapperw process had an attached console. This was causing several small issues: performance decay in case of intensive logging, irrelevant warning about QuickEdit mode being enabled, and inability to use certain locales when the OEM encoding, usually used for consoles, was not compatible.
Fix a crash in WrapperManager.nativeGetPortStatus() caused by an unhandled return code while checking on the status of the port to be used by the JVM to connect to the Wrapper (Windows only). This problem was introduced in version 3.5.27, but has only been seen once. The crash is only possible immediately after the JVM is launched. It can also be worked around by using a pipe rather than a socket with the wrapper.backend.type property.
Add new property wrapper.java.version.fallback which will be used in case the Wrapper fails to parse the output of 'java -version'. If this property is not set, the Java version will be resolved to the lowest supported version, but the Wrapper will stop when certain properties requiring the Java version are used. 2ff7e9595c
