Change log

1.1.0 [unreleased]

WIP.

1.0.1 [2022-06-21]

  • Fixed addition of new UCI files which were not previously already present on the file system

1.0.0 [2022-05-10]

Features

  • The SIGUSR1 signal can be now used to interrupt the interval sleep and check for configuration changes again
  • Made the procd respawn parameters configurable
  • The agent now stores the any UCI configuration which is overwritten by OpenWISP with the goal of restoring it if the piece of configuration overwritten by OpenWISP is removed
  • Added management_interval and registration_interval options

Changes

Backward incompatible changes

  • Remove unneeded SSL package implementation definitions

Other changes

  • Made configuration checksum persistent to fix 2 problems:
    1. If the openwisp-config daemon is restarted (e.g. by the openwisp- controller via ssh) after it already downloaded the latest checksum but before it has applied the configuration, all further calls of configuration_changed() (until CONFIGURATION_CHECKSUM is deleted, e.g. by a reboot) will imply that everything is already up-to-date, although the configuration was never applied
    2. prevents the configuration from being downloaded and written again after a reboot
  • Do not wait for management interface during registration: If openwisp-config is not registered yet, do not wait for the management interface to be ready because we can assume the management interface configuration is not present yet
  • Increased report status retries: in some cases the report status operation may fail because the network reload could take a few minutes to complete (e.g.: in mesh networks scenarios) and therefore the agent must be a bit more patient before giving up
  • Refactored init script to make it more consistent with the best practices used in the OpenWrt community
  • If the agent receives 404 response from the server when downloading the configuration checksum, after the number of attempts specified in checksum_max_retries fail, the agent assumes the device has been deleted from OpenWISP and exits

Bugfixes

  • Use configured curl timeout values in default configuration test; Without this fix, it's possible that the configuration test fails while the regular checksum fetch succeeds
  • Ensured config download error is detected: adding the --fail flag to curl makes it exit with a non zero exit code in case the server respond with an HTTP status code which is not 200 OK, without this fix, a bad response is interpreted as a valid configuration and the agent removes the old configuration, then installs the new configuration, which fails and the router remains with an empty configuration, effectively causing a disruption of service
  • Fixed post-registration-hook logging line which was mistakenly mentioning post-reload-hook instead of post-registration-hook
  • Fixed service reload handling for unnamed uci sections: the openwisp agent modifies the configuration on first contact by rewriting all anonymous UCI sections into named UCI sections. This causes almost all services to be restarted even though the configuration has not really changed. To prevent this from happening, the md5sums are rewritten after calling openwisp-uci-autoname; this will reload only those services whose configuration has actually been changed
  • Remove applying_conf control file after status report: without this fix, the agent may be reloaded before the status is reported to OpenWISP Controller, leaving the device in "modified" config status even though the configuration has been already applied
  • Fixed HTTP response codes on newer cURL versions
  • Handled agent crashes when registration is not successful
  • Verify downloaded tarball against the configuration checksum
  • Fixed a bug in the bootup_delay feature which caused it to not work unless an extra dependency was being used; the need on the extra undocumented dependency has been eliminated
  • Fixed unhandled naming conflicts when anonymous configuration are renamed via the openwisp-uci-autoname script

0.5.0 [2020-12-20]
