What causes "CFST 测速结果 IP 数量为 0，跳过下面步骤..." in XIU2/CloudflareSpeedTest?

Run ./cfst -o result_hosts.txt manually and check it executes at all

CFST 测速结果 IP 数量为 0，跳过下面步骤...

Error message

CFST 测速结果 IP 数量为 0，跳过下面步骤...

What it means

The macOS twin of cfst_hosts.sh: in _UPDATE(), after ./cfst -o result_hosts.txt the check at script/cfst_hosts_mac.sh:38 fires when the output file is missing. CFST only writes result_hosts.txt when at least one IP passes its filters, so the script reports '0 IPs' and exits 0, leaving /etc/hosts and nowip_hosts.txt unchanged.

	# 下面这行代码是 "找不到满足条件的 IP 就一直循环测速下去" 才需要的代码
	# 考虑到当指定了下载速度下限，但一个满足全部条件的 IP 都没找到时，CFST 就会输出所有 IP 结果
	# 因此当你指定 -sl 参数时，需要移除下面这段代码开头的 # 井号注释符，来做文件行数判断（比如下载测速数量：10 个，那么下面的值就设在为 11）

Solutions

Run ./cfst -o result_hosts.txt manually and check it executes at all
If macOS blocks the binary: xattr -d com.apple.quarantine ./cfst && chmod +x ./cfst
Relax CFST arguments or refresh ip.txt, then re-run the script
For launchd/cron, make the job cd into the script directory first
Optionally replace exit 0 with _UPDATE per the in-file comment to loop until a qualifying IP is found (bound the retries)

Example fix

# script/cfst_hosts_mac.sh (before)
./cfst -o "result_hosts.txt"
# (after)
./cfst -o "result_hosts.txt" || { echo "cfst run failed (exit $?)" >&2; exit 1; }

Defensive patterns

Strategy: retry

Validate before calling

[ -x ./cfst ] && [ -f ip.txt ] || { echo 'cfst/ip.txt missing' >&2; exit 1; }

Try / catch

./cfst -o result_hosts.txt || { echo "cfst exited $? (Gatekeeper?)" >&2; exit 1; }

Prevention

After downloading cfst on macOS, clear the quarantine bit: xattr -d com.apple.quarantine cfst; chmod +x cfst
Test ./cfst -h manually before wiring the script into cron/launchd
For launchd, set the working directory in the plist or cd inside a wrapper script

When it happens

Trigger: All IPs failed CFST's filters this run; ./cfst did not execute (binary missing or not executable — note macOS Gatekeeper quarantines downloaded binaries; or ip.txt absent); Cloudflare test ports blocked by the network.

Common situations: Downloaded cfst blocked by macOS security (needs xattr -d com.apple.quarantine cfst) so no result file is ever produced; strict user-added -sl/-t filters; a cron/launchd job running from the wrong working directory.
