FSlint with database support

[dipietro-salvatore]

Fslint with SQLite support to avoid to hash twice the same file during the findup process.

Do you have any metrics how much this would speed things up?

[dipietro-salvatore]

Well, In my case it made the difference. I wanted to find all the duplicated file on an entire HDD. This allowed me to:

• Suspend and restart the scanning as many time I wanted (and not leave my pc on for days)
• Check in the future without rescanning everything if new finds are copies
• Compare the data with also other HDD

I found it very useful and save me a lot of time. It does not impact in any way the program performance but it reduces the time necessary to re-scan the same folder/disk in the future.

It should be used under root only?

Hi @perfect7gentleman,
I just updated the git to fix the problem. Please, re-clone the git repo.
Here some instructions to run in the terminal:

cd /usr/share/
sudo mv fslint fslint-orig
sudo git clone https://github.com/dipietro-salvatore/fslint.git fslint

Let me know if this fix the issue.
Thanks

[perfect7gentleman]

Permission fixed,
But

Traceback (most recent call last):
  File "/usr/lib/python-exec/python2.7/database", line 48, in <module>
    cursor.execute('''SELECT * FROM files WHERE path IN ({seq})'''.format(seq=','.join(['?']*len(files_list))), ([f for f in files_list]))
sqlite3.OperationalError: too many SQL variables

also it cannot find any dupes at all, in other words it doesn't work

[dipietro-salvatore]

can you please provide more information about the system and error?
I am not able to reproduce the error.

[perfect7gentleman]

System - Gentoo.
Error is gone. But it doesn't find dupes anyway.

[perfect7gentleman]

Nope. It's back.

[perfect7gentleman]

What info is needed?

[dipietro-salvatore]

I did some changes to the repo.
Can you please to clone it and run it again?

[perfect7gentleman]

The same error

Traceback (most recent call last):
  File "/home/MZ7WD240HAFV/Temporary/fslint/fslint/supprt/database", line 49, in <module>
    cursor.execute('''SELECT * FROM files WHERE path IN ({seq})'''.format(seq=','.join(['?']*len(files_list))), ([f for f in files_list]))

[dipietro-salvatore]

To be able to replicate the error, Can you please tell me how many files to you have on the scanning folder(s)?

[perfect7gentleman]

129.5 MiB (135,783,482)
8,943 files, 1,870 sub-folders

[dipietro-salvatore]

I changed the way how the script retrieve the data from the DB. Can you please try now?

[perfect7gentleman]

Now it works.

54.1MB wasted in 2547 files (in 993 groups)

[dipietro-salvatore]

Happy to ear that! Out of curiosity, do you know how much time it takes the first time compared to the second time using the DB (if you haven't deleted the files immediately)?

[perfect7gentleman]

rather fast
