Maximum call stack size exceeded #9
Description
When I used "until" with a 1000 or so iterations, node is saying "Maximum call stack size exceeded". Is there a limit to the number of iterations? My code was working and I think I've coded it properly. FWIW, here is my code.
async.until(function() {
return opt.eof && !buf;
}, function(cb) {
var delim, match, parts;
if ((parts = regex.exec(buf))) {
match = parts[0], delim = parts[1], buf = parts[2];
switch (opt.delimType) {
case 'prefix':
opt.data = prefix + match;
prefix = delim;
break;
case 'suffix':
opt.data = match + delim;
break;
default:
opt.data = match;
}
callback(opt);
return stopChk(cb);
} else if (opt.eof) {
opt.data = prefix + buf;
callback(opt);
opt.stop = true;
return stopChk(cb);
} else {
return fs.read(fd, inBuf, 0, opt.bufSize, null, function(err, bytesRead) {
if (err) {
return cb(err);
} else {
if (bytesRead) {
buf += inBuf.toString('utf8', 0, bytesRead);
return cb();
} else {
opt.eof = true;
return fs.close(fd, cb);
}
}
});
}
});
return function(err) {
if (!opt.stop) {
opt.err = err;
return callback(opt);
}
};
)
