The telemetry collect the Go runtime/metrics and forward it to questdb instance in localhost.

all: un-export HostsFiles and Zones fields on Environment

2022-06-12T07:29:31Z

Previously those fields exported because web client need it to initialize the content for /hosts.d and /zone.d pages. Since we now have HTTP API for that, web client can call get request to the respective API without depends on the environment.

all: fixes HTTP API for updating environment

There are two issues when updating environment. One is on the front, where debug value is send as string. Another one is the back, where new environment overwrite all of options where it should only update only DNS server options and Debug fields.

_www/block.d: fix the variable names on hosts block.d

2022-06-12T06:02:16Z

In the commit 0b92dbb8463d, we changes the field HostsBlocks in Environment to HostBlockd, but we forgot to changes the code in the web. This changes fix this issue.

all: export and rename the hostsBlock type to Blockd

2022-05-22T14:51:47Z

In the Environment, we have a field HostsBlocks that reference an unexported type hostsFile. In order for any package to be able to use this field, we need to export this type. While at it, we rename the type from hostsBlock to Blockd to make it simple and consistent with name.

all: fix panic if a nil HostsFiles and/or Zones is accessed

2022-04-22T17:16:08Z

all: always call Environment init

2022-04-19T16:57:51Z

This is to make sure that all required fields that are empty in the configuration initialized to its default values.

all: add option to set the base directory

2022-04-19T16:30:09Z

Previously, running an instance of rescached assume that all configurations and cache are located in /etc/rescached and /var/cache/rescached. It possible that we may want to use different base directory (or $PREFIX, in the auto tools terms), for example "/opt/rescached" or as showed in the "dev" task in the Makefile, we use "_test" as base directory for running test instance. This changes also fix an error when loading hosts file from non-existant hosts.d directory.

all: refactoring the hosts blocks format and location

2022-04-19T15:18:26Z

This changes add new directory called "block.d" under rescached. This directory contains hosts file fetched from URL defined in hosts block configuration. In this way, we did not mixed between user created hosts file and external hosts file. In the configuration file, we changes the hosts block format from single line hosts_block = into subsection with dynamic name, [block.d ""] name = url =

all: apply suggestions from linter

2022-04-16T11:32:36Z
