The C++ and PHP parsers for zm.conf and /etc/zm/conf.d/*.conf used fgets
with a 512-byte buffer, silently truncating any line longer than that.
There was also no way to split a value across multiple lines, so editors
hit the cap with no workaround.
Accept a trailing backslash (with optional whitespace before the newline)
as a line-continuation marker. Leading whitespace on continuation lines
is stripped so users can indent for readability without it leaking into
the value. Three parsers all read the same files and must agree:
- src/zm_config.cpp: switch to std::ifstream + std::getline so a single
physical line is no longer capped at 512 bytes, then join continuation
lines before running the existing pointer-based parser
- scripts/ZoneMinder/lib/ZoneMinder/Config.pm.in: accumulate a logical
line across trailing-backslash physical lines
- web/includes/config.php.in: drop the 512-byte fgets cap and accumulate
in the same way
tests/zm_config.cpp covers three cases against the C++ parser: a
three-segment continuation joins to "firstsecondthird" with leading
whitespace stripped, a bare backslash inside a value is preserved
(C:\Users\zm), and a 1500-byte single line survives intact.
