Postinst logging reimplementation
cover Postinst logging reimplementation
From: Chen Qi <[email protected]>
Goal:
1. Enable postinst logging if 'debug-tweaks' is in IMAGE_FEATURES
2. Make rpm, opkg and dpkg not depend on IMAGE_FEATURES and POSTLOG
Implementation:
1. The run-postinst scripts will log outputs and errors if /etc/.enable_postinst_logging is present.
2. The log location is always /var/log/postinstall.log. Do not allow configuration, because this is mainly for debugging purpose and /var/log/postinstall.log is a good place. Making it configurable is not necessary.
The following changes since commit a9f5bf0ed398bf9cb861feaa8b6fefd8645b1d09:
sanity.bbclass: Attach the missing value to a format string. (2013-05-13 21:54:40 +0300)

PATCH 1/4 image.bbclass: add postinst_enable_logging
From: Chen Qi <[email protected]>
Add a function postinst_enable_logging, so that when 'debug-tweaks' is in IMAGE_FEATURES, we create .enable_postinst_logging under /etc, which is used by run-postinst scripts to determine whether to log or not.

PATCH 2/4 dpkg: modify the run-postinst script to enable postinst logging
In reply to [email protected]From: Chen Qi <[email protected]>
Enable postinst logging according to the existence of the file /etc/.enable_postinst_logging.
In this way, the postinst logging is enabled if 'debug-tweaks' is in IMAGE_FEATURES, and at the same time, we avoid unnecessary rebuilt if IMAGE_FEATURES is changed.

I'm not very keen on dot-files in etc, and as the postinst init script is one-shot shouldn't it be deleting that configuration file once it's completed?

I do not think this should go here, maybe better to have it in the /etc/default dir and named postinst, since that matches what other init
related scripts do and source the file in each postinst script, it should also have a standard guard to check existance of the file and checks something like a "ENABLED" variable instead? This could also be extended for getting the log file location also.

Thanks a lot.
I'll follow your advices and send out a v2.
