NOTE

Due to schema changes, be sure to remove your database after upgrading and before restarting:

systemctl stop pmond
rm -f /etc/pmon3/data/data.db
systemctl start pmond

• Randomizing pidlist for the topn command when more that 20 apps are running #32
• Upgrades golang to 1.22

Full Changelog: https://github.com/joe-at-startupmedia/pmon3/compare/v1.15.0...v1.15.1

• Changes how pmond loads processes from both Apps Config (takes precedence) and the database #30
• Adds the ability to initialize processes only specified in the Apps Config #30
• Adds the ability to start processes specified in the Apps Config which haven't already been started and persisted to the database #30
• Implements a dependency resolution system #31
• Adds the ability to debug dependency resolution without restarting processes #31
• Adds the ability to wait (n) milliseconds after initializing a dependent process #31
• Adds more flags to log, logf and topn commands
• Reloads the configuration files on each command execution, omitting the need for restarting pmond
• Adds a --blocking flag to the init command which only returns a response after all processes have been queued

NOTE

Due to schema changes, be sure to remove your database after upgrading and before restarting:

systemctl stop pmond
rm -f /etc/pmon3/data/data.db
systemctl start pmond

Allows the process to inherit all of the users groups #27
Remove hashing from log names and improve documentation on --log versus --log-dir #29
Process log is accessible with adequate permissions by the managing user from --user #14
Adds the ability to specify environment variables #28

Switching the default IPC mechanism between the daemon and the cli from unix domain sockets to shared memory, significantly increasing cli command response times.

• Suppresses configor failure message from loading non-existent configuration files #25

• Implements configor to simplify configuration boilerplate and allow overrides via environment variable specifications
• Implements xipc to provide an abstraction for swapping out underlying IPC mechanisms (using build tags) including the addition of shared-memory

• fixes a race condition in the golang-ipc library

• enhances log level specificity through the PMON3_DEBUG environment var
• properly handle/log particular error scenarios
• Makefile improvements
• Adding code coverage via integration tests

• Adds an -a flag to the log command which outputs compressed/rotated files in addition to the current log file
• Adds the ability to specify an application config from which to reference upon pmond initialization, as opposed to manually running several exec commands.
• fixes nil pointer dereference panics on fresh installations

• Adds an -a flag to the log command which outputs compressed/rotated files in addition to the current log file
• Adds the ability to specify an application config from which to reference upon pmond initialization, as opposed to manually running several exec commands.
