=== Enhancements
* cmd/rescached: add sub command to print the current version
Running "rescached version" now will print the program version.
* support SVCB record (type 64) and HTTPS record (type 65)
The latest update on "lib/dns" package support RFC 9460, SVCB record
(type 64) and HTTPS record (type 65).
=== Chores
* all: replace module "share" with "pakakeh.go"
The module "share" has been moved to new repository at SourceHut and
we rename it to make it more unique instead of common English words
"share".
* all: move repository to SourceHut
The new repository and project page for rescached is at
https://sr.ht/~shulhan/rescached .

Using ".reuse/dep5" has been deprecated since REUSE v3.2.
|
|
Remove items that has been finished or not related to current
implementation.
|
|
|
|
The web user interface can be run using existing rescached server by
setting the SERVER value in class Rescached (_www/rescached.js).

Seems like the latest Go require the minor version to be explicitly
defined [1][2].

Fix the code as recommended by linters, for example using context for
HTTP client request, using 0600 for file permission, using string
concatenation instead of fmt, using "%w" for error, and reorder defer.

* all: remove loading system hosts file::
Loading and caching system hosts file (for example, /etc/hosts in
POSIX) will leaks internal hosts if the rescached server is open to
public.
The system hosts file are handled by nssswitch.conf "files" internally
so no need to loading it.
* cmd/resolver: replace "math/rand" with "crypto/rand"::
The random number from "math/rand" is predictable if the seed is
known. Even though the random number here is only for generating unique
request ID, we still need to prevent this by using more secure random
number.

= Release share v0.50.1 (2023-11-05)
This release bring many enhancements to "lib/memfs", a library for
caching file system in memory.
=== Enhancements
* lib/memfs: return nil in AddChild if file not exist
* lib/memfs: quote the path in the returned error
* lib/memfs: add method Child to Node
* lib/memfs: call the Init method in the embedded file
* lib/memfs: include empty directory
* lib/memfs: re-scan directory content on Node’s Update
= Release share v0.50.0 (2023-10-04)
This release bring many enhancements thanks to linters like revive,
fieldaligment, and shadow.
This release also replace "math/rand.Seed" with "crypto/rand".
Since Go 1.20 the "math/rand.Seed" is considered deprecated (the initial
value of rand is seeded automatically, not zero).
Now, it is the time to replace "math/rand" with more secure random
number generator, from "crypto/rand".
This changes affect tests in package "lib/email", "lib/http", and
"lib/stmp".
= Release ciigo v0.10.1 (2023-11-07)
In this release, update on asciidoctor-go add new features to parse
unordered list with '-' and some bug fixes related to rendering list.
The update on share module fix for permission error when scanning using
memfs and HTTP redirect for request to directory that does not end with
slash.

The update on share module affect the following changes,
* lib/dns: removing dns.ZoneRecords, replacing it with
map[string][]*dns.ResourceRecord
* lib/dns: file Name in Zone renamed to Origin
* lib/dns: replace call to Caches.InternalPopulate with
InternalPopulateZone that accept zone as parameter

The golangci-lint become unusable.
Even running "make" on the their master branch does not works.
Since I use go tip (master) on local, sometimes golangci-lint does not
run.
This changes replace golangci-lint with "go vet", fieldalignment and
shadow (from x/tools), and revive.

DNS library, including
* lib/dns: simplify unpackDomainName return value for end
* lib/dns: use the packet length to derive current offset
* lib/dns: handle zone file with CRLF line ending

While at it, rename the README.adoc to README and made symlink
to it as README.adoc.

This release refactoring the resolver command as CLI to rescached server.
The resolver command now can manage environment, caches, hosts.d, and
zone.d in the server; not just query.
|
|
Some block code in the examples are not formatted correctly due to
spaces.
|
|
|
|
|
|
On build.kilabit.info, 2 out 5 building this repository return an error
dial tcp 127.0.0.1:5381: connect: connection refused
This is due to server is not ready accepting connection while the test
for client is already running.
|
|
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.
|
|
On refactoring,
- standardize the method names on the rescached.js to match with the
Client, for example prefixing block.d operations with Blockd.
- use the GET /block.d, GET /hosts.d, GET /zone.d to fetch the
resources instead of using GET /environment for all.
On bug fixes,
- fix updating SOA record on zone.d due to refactoring
|
|
When calling API for zone.d record delete, client send the fully
qualified domain name on record to be deleted, but caches store only
the subdomains internally.
This cause the delete action fail, because no internal record match
with request.
|
|
This is to provide an HTTP API to fetch list of hosts.d files on the
server.
|
|
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.
|
|
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.
|
|
This changes affect the dns Server where all caches related methods has
been moved to field Caches.
|
|
The test is conducted by running the server and call the HTTP API using
the Client methods.
|
|
We have HTTP API to enable or disable block.d by batch by passing all
block.d records.
The name of HTTP API is /v2/block.d/update and this is duplicate with
API to update the content of hosts in block.d.
This changes fix this by creating new HTTP API /v2/block.d/fetch
that fetch the latest hosts file from specific block.d by its name.
While at it,
- reformat html and JavaScript files using js-beautify
- rename constants and methods for HTTP APIs
- add and update comments for some HTTP APIs
|
|
Since we have exported the Blockd type from rescached package, any
Blockd operation on the HTTP server and on the client on cmd/resolver
can use it instead of using interface{}.
|
|
Given the following command
$ resolver block.d
It will print all hosts in block.d in the JSON format, for example
{
"pgl.yoyo.org": {
"Name": "pgl.yoyo.org",
"URL": "http://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts\u0026showintro=0\u0026startdate[day]=\u0026startdate[month]=\u0026startdate[year]=\u0026mimetype=plaintext",
"LastUpdated": "2022-04-20 01:54:30 WIB",
"IsEnabled": false
},
"someonewhocares.org": {
"Name": "someonewhocares.org",
"URL": "http://someonewhocares.org/hosts/hosts",
"LastUpdated": "2022-04-20 00:53:22 WIB",
"IsEnabled": false
},
"winhelp2002.mvps.org": {
"Name": "winhelp2002.mvps.org",
"URL": "http://winhelp2002.mvps.org/hosts.txt",
"LastUpdated": "2022-04-20 01:35:38 WIB",
"IsEnabled": false
}
}
|
|
Given the following request,
GET /api/block.d
It will return list of hosts in block.d as JSON format:
{
"data": {
"<name>": <Blockd>
...
}
}
