Is it possible to ignore comment?

It seems the comments in Java and C are included in the similarity detection. It is possible to ignore all comments when do the comparing?

[test on V5.3.1] unexpected behaviors when upgrade to V5.3.1

Hi, Guys. I do some test on the engine V5.3.1.

scan file	KB	comment
1.py	file1	no modified, just rename
2.py	file2	partial content of file2
3.py	file1, file2	mixed with file1 and file2

about V5.3.0, the result is expected as above
but about V5.3.1, the result is unexpected. the scan result about 2.c and 3.c is that they matched nothing
output_5.3.0.txt
output_5.3.1.txt
test_case.zip

file-based matches appear to prefer 3rd-party github origin over authoritative nuget repo

This may be operator error, or may be an opportunity for matching algorithm improvement?
In testing SCANOSS Workbench (1.12.3) as well as scanoss.js & scanoss.py (multiple recent versions eg via docker ghcr.io/scanoss/scanoss-py:latest), primarily with projects using .net core & framework libs, I found scanoss 'found' 100% match on common .net lib files which various 3rd-parties (possibly inadvertently) included in their github project releases rather than matching on the authoritative .net package - often with src on github, but binary first published on nuget.
Examples:
Azure.Security.KeyVault.Secrets.dll - from Azure .NET SDK v4.1.0 / file v4.100.20.41103 / md5:5a048b36e0402c521fe93272a2f9aab2 / sha256:0fcdcd4b78955ffcbfa34ef181322c1fcfd983ce8612c335f10dced61452213e
Src published 8/11/202: https://github.com/Azure/azure-sdk-for-net/releases/tag/Azure.Security.KeyVault.Secrets_4.1.0
Bin published 8/12/202: https://www.nuget.org/packages/Azure.Security.KeyVault.Secrets/4.1.0
3rd-party "matched" pkg published 11/23/2020: https://github.com/folkehelseinstituttet/Fhi.Smittestopp.Verification/releases/tag/v0.1.0-alpha
Microsoft.Extensions.Primitives.dll - from MS .NET v8.0.0 / file v8.0.23.53103 / md5:bb3af05bc071ceba027d1dc5fa255ec4 / sha256:f9f47907a041067d9bc1b9a9f516009b6ca0a9c6325ce83527883cc0d053dfa5
Src published 11/14/2023: https://github.com/dotnet/core/releases/tag/v8.0.0
Bin published 11/14/2023@13:23z: https://www.nuget.org/packages/Microsoft.Extensions.Primitives/8.0.0
3rd-party "matched" pkg published 11/14/2023@19:00z: https://github.com/danielpalme/ReportGenerator/releases/tag/v5.2.0

This may be a byproduct of how MS proj maintainers have handled src releases on github and bin releases via nuget, but when a dozen or more files on a project have this occur, it consumes notable extra time to straighten out the sboms and ensure lic/cve issues are recognized and addressed.
If this isn't something scanoss engine changes can address, any suggestion as to how to minimize having to redo the straightening on scans for subsequent project builds and/or on other projects using the same lib would be helpful - or suggestions on where to ask upstream or downstream of the scanoss engine project.
I'm sure others may encounter as the scanoss user-base grows, thanks.

libhpsm.so download

scanoss has -H parameter, 'libhpsm.so' must be present in the system.
I don't know where I can find 'libhpsm.so', can you provide me a download url?

scanoss -h
···
Configuration:
-w Treats TARGET as a .wfp file regardless of the actual file extension.
-H High Precision Snippet Match mode, 'libhpsm.so' must be present in the system.
-e Expect matching extensions to equal the file extension being scanned (default: off).
-s SBOM Use assets specified in JSON SBOM (CycloneDX/SPDX2.2 JSON format) as input to identification.

Space occupation problem

When generating code index data, a small project will generate a large amount of data, almost a few G, is there any way to compress the data, it is acceptable for small project samples, but the number of lines of code is large , It takes up too much space。

Use engine components and compare with local LDB knowledge base

Does the engine use the local LDB library for scanning? Is it a problem? There is also why the source file is dug into the ldb, and the corresponding data information cannot be scanned when the scanoss is executed?

I have studied for a long time, but I haven't reached a conclusion. I hope to get answers here!

I used engine steps and results：

no result

Hello, I use engine & ldb & minr master branch to build the system on different systems (Ubuntu, Centos
7) , and use the following test command: scanoss webhook-1.0/setup.py, but whether it is a file or a compressed package, the result is 0, no code snippet hits the result:
{
"webhook-1.0/setup.py": [
{
"id": "none",
"elapsed": "0.001200s"

}

The log result is:

query very slow

Hello, there is a question. With the increase of ldb data, the query becomes slower . Now the database has about 600GB of data, and it takes a long time to query a snippet For example, this is the query result
"id": "snippet",
"status": "pending",
"lines": "1-49",
"oss_lines": "13-61",
"matched": "97%",
"purl": [
"pkg:github/v2v3v4/BigWorld-Engine-2.0.1"
],
"quality": [],
"cryptography": [],
"server": {
"hostname": "localhost.localdomain",
"version": "4.3.8",
"flags": "0",
"elapsed": "57.364302s"
}, When there are many query files, it will take a few days to get a result. My machine configuration is AMD Ryzen Threadripper 3970X 32-Core Processor, 128Gb memory, 30Tb mechanical hard disk, Centos OS 7.8, what is the best way to find it? Speeding up, because I noticed that the system resources were used very little during the actual query. I don't know what went wrong. I want to ask if there are any good suggestions. This is the result of executing scanoss -t:
Analysis complete
Test executed in 401967ms
Average file scanning time is 4019ms
Performance is 24 fingerprints per second

Segmentation fault

Hi, @mscasso-scanoss

Meet unexpected exceptions : "segmentation fault". What should I do for it?

"M" option means that it will look for NUMBER of different components in the scanning file (MAX 9), right? did I use it incorrectly?
Is there any options which can help to looking for different snippets in the scanning file, and show all the matching parts of snippets. for examples: the scanning file lines 0 ~ 100 matches flask/cli.py(...), lines 300 ~350 matches flask/ctx.py(...), and lines 500 ~ 570 matches docker/compose/project.py(...)
