[FriesI23]

Maintainer: FriesI23 Qin / @FriesI23
Compile tested: should be universal, Debian 12, OpenWrt 23.05.05
Run tested: i386_pentium4, vm on proxmox 8.3 using openwrt.sh, OpenWrt 23.05

Also tested: aarch64_generic, NanoPi R4S, OpenWrt 23.05.04

Description:

• Migrate retry_count to retry_max_count in the script to fix infinite retry loop.
• Fix signature expiration issue during retries.

This script copy from FriesI23/ddns-scripts_tencent_cloud which I maintain.

[FriesI23]

Found some update_*.sh scripts also use retry_count, while the correct var name is retry_max_count. This cause "Error Max Retry Counter" config not working (always retries infinitely).

@feckert Should notify specific maintainers about this?

$grep -rl 'retry_count' ./net/ddns-scripts/files/usr/lib/ddns | xargs grep -L 'retry_max_count'

./net/ddns-scripts/files/usr/lib/ddns/update_cloudflare_com_v4.sh
./net/ddns-scripts/files/usr/lib/ddns/update_dnspod_cn.sh
./net/ddns-scripts/files/usr/lib/ddns/update_godaddy_com_v1.sh
./net/ddns-scripts/files/usr/lib/ddns/update_luadns_v1.sh

@FriesI23 nice catch.
You are doing different things in one commit.
Can you please split them up. So we have exact one commit for each change task and can you also fix retry_max_count for the different providers. Also separate this changes into different commits.

Thanks.

[FriesI23]

Make separate commits √, but not sure if I need to use two PR for this.
For other providers, I will submit via another PR.

Fine with me.

Please also bump the PKG_RELEASE by one in each commit.

Done but suspended for Long-Time queued CIs ;-(

Thanks merged!
CI/CD is not needed because this are only script changes.
