[mod_command] COND compares strings by length, not by content

[ukolovda]

Describe the bug
cond command returns wrong result for quoted strings:

cond '12' >= '19' ? true : false
give true but should returns false.

To Reproduce
Steps to reproduce the behavior:

append to dialplan:

<action application="set" data="a=${cond('12' >= '19' ? true : false)}" />

FS log:

EXECUTE [depth=0] sofia/internal/00001@freeswitch set(a=true)
2025-01-10 02:18:42.150764 96.80% [DEBUG] mod_dptools.c:1671 SET sofia/internal/00001@freeswitch [a]=[true]

Expected behavior

Quoted strings should compares as a string, as documented:

Package version or git hash

• Version [e.g. 1.10.12]

Seems the code is wrong:

freeswitch/src/mod/applications/mod_commands/mod_commands.c

Lines 2261 to 2265 in 6a5ac7e

	a_is_num = (switch_is_number(s_a) && !a_is_quoted);
	b_is_num = (switch_is_number(s_b) && !b_is_quoted);
	a_f = a_is_num ? atof(s_a) : (float) strlen(s_a);
	b_f = b_is_num ? atof(s_b) : (float) strlen(s_b);

Lines 2285 to 2287 in 6a5ac7e

	case O_GE:
	is_true = a_f >= b_f;
	break;

apparently the code only handles strings for the == and != operators. The operators are for numeric values. Do you have a use case where need to know which string is greater?
