scanDir do not return an array of files

[Annubis45]

The result of doesn't return arrays of good files and bad files. It returns an array with the path scanned.

Please refer to the docs: https://github.com/kylefarris/clamscan#note

Relevant passage:

The goodFiles and badFiles parameters of the end_callback callback in this method will only contain the directories that were scanned in all but the following scenarios:

• A file_callback callback is provided, and scanRecursively is set to true.
• The scanner is set to clamdscan and scanRecursively is set to false.

Hi,

Here my code:

        console.log('AnalyseFiles:');
        const clamscan = await new NodeClam().init({ scanRecursively: false});
        const version = await clamscan.getVersion();
        console.log(`ClamAV Version: ${version}`);

        clamscan.scanDir('./files/', (err, goodFiles, badFiles, viruses) => {
            if (err) return console.error(err);

            if (badFiles.length > 0) {
                console.log(`${path} was infected. The offending files (${badFiles.join (', ')}) have been quarantined.`);
                console.log(`Viruses Found: ${viruses.join(', ')}`);
            } else {
                console.log("Everything looks good! No problems here!.");
            }
        },
        (error, file, isInfected) =>{
            console.log(`${file} is ${isInfected ? 'infected' : 'clean'}`);
        });

and the result is :

ClamAV Version: ClamAV 0.103.5/26459/Sun Feb 20 10:22:37 2022
Attachment is infected
ContentVersion is infected
Everything looks good! No problems here!

files directory is : ---files ----- Attachment -----------file1 -----------file2 -----------file3 ----- ContentVersion -----------file4 -----------file5

[kylefarris]

You would need to set scanRecursively to true if you want to see the individual files that are infected.

[Annubis45]

Thank you for your answser.

When I set scanRecursively to true, I get this error:

node_modules/clamscan/index.js:1529
    if (err) return hasCb ? endCb(err, goodFiles, badFiles,viruses, []) : reject(new NodeClamError({ badFiles }, err));

[kylefarris]

That can't be the entire error. That's just the stacktrace showing where the error was thrown. I'd need to know what error was actually thrown here as the could be any number of things.

Hi,

I restarted eveything from scratch:

my code:

console.log('AnalyseFiles:');
const clamscan = await new NodeClam().init({ debugMode:true, scanRecursively: true});
const version = await clamscan.getVersion();
console.log(`ClamAV Version: ${version}`);
clamscan.scanDir('./filesdir/', (err, goodFiles, badFiles, viruses) => {
        if (err) return console.error(err);

        if (badFiles.length > 0) {
            console.log(`MYLOG -  it was infected. The offending files (${badFiles.join (', ')}) have been quarantined.`);
            console.log(`MYLOG - Viruses Found: ${viruses.join(', ')}`);
        } else {
            console.log("MYLOG - Everything looks good! No problems here!.");
        }
    },
    (error, file, isInfected) =>{
        console.log(`MYLOG - ${file} is ${isInfected ? 'infected' : 'clean'}`);
    });

My directory : ---filesdir ----- rep1 -----------file1 ----- rep2 -----------file1 -----------file2

And the result:

And when I put breakpoints in callback functions, I never reach it.

I also tried the promise syntaxe and stay stuck in it. I got the same result and never reach the next line.

const {goodFiles, badFiles} = await clamscan.scanDir('./filesdir/');

I'm sorry if this thread has changed since the start. If you want I can open a new one.

[Annubis45]

My analyse is : scandir need a resolve/reject result, but when I call it with my option, it does: scandir ==> scanFiles ==> doscan ==> ...

Scandir return a promise that make a "return scanfile(...)" and scanfile return a promise (line 1978) So, my guess is the promise of scandir is never resolved.

line 1978 : return this.scanFiles(files, endCb, fileCb);

IMO, it should be replaced by something like this:

const scanResult= await this.scanFiles(files, endCb, fileCb);
return hasCb
        ? endCb(null, [], [])
        : resolve(scanResult);

[kylefarris]

That's more like it. Yeah, from looking at your debug log, it all looks like it's working up to a point. I haven't had a chance to look at the source code yet but your analysis seems correct in theory. Why don't you see if you can fix the issue and run some tests? A PR would be really help since I'm quite busy this week.

Thanks for all your hard work.

[Annubis45]

ok, I'll try !

[kylefarris]

FTR, this issue was fixed in v2.1.1.
