All paths stored in ``.bitrot.db`` are relative so it's safe to rescan
|

a folder after moving it to another drive. Just remember to move it in
|

a way that doesn't touch modification dates. Otherwise the checksum

database is useless.

a folder after moving it to another drive.

|
||||
Performance
|
||||
-----------
|
||||
|
||||
Obviously depends on how fast the underlying drive is. Historically
|
||||
the script was single-threaded because back in 2013 checksum
|
||||
calculations on a single core still outran typical drives, including
|
||||
the mobile SSDs of the day. In 2020 this is no longer the case so the
|
||||
script now uses a process pool to calculate SHA1 hashes and perform
|
||||
`stat()` calls.
|
||||
Obviously depends on how fast the underlying drive is. Since bandwidth
|
||||
for checksum calculations is greater than your drive's data transfer
|
||||
rate, even when comparing mobile CPUs vs. SSD drives, the script is
|
||||
single-threaded.
|
||||
|
||||
No rigorous performance tests have been done. Scanning a ~1000 file
|
||||
directory totalling ~5 GB takes 2.2s on a 2018 MacBook Pro 15" with
|
||||
a AP0512M SSD. Back in 2013, that same feat on a 2015 MacBook Air with
|
||||
a SM0256G SSD took over 20 seconds.
|
||||
No rigorous performance tests have been done. Scanning a ~1000 files
|
||||
totalling ~4 GB takes 20 seconds on a 2015 Macbook Air (SM0256G SSD).
|
||||
This is with cold disk cache.
|
||||
|
||||
On that same 2018 MacBook Pro 15", scanning a 60+ GB music library takes
|
||||
24 seconds. Back in 2013, with a typical 5400 RPM laptop hard drive
|
||||
it took around 15 minutes. How times have changed!
|
||||
Some other tests back from 2013: a typical 5400 RPM laptop hard drive
|
||||
scanning a 60+ GB music library took around 15 minutes. On an OCZ
|
||||
Vertex 3 SSD drive ``bitrot`` was able to scan a 100 GB Aperture library
|
||||
in under 10 minutes. Both tests on HFS+.

||||

Tests
|
||||
-----
|
||||
|
||||
There's a simple but comprehensive test scenario using
|
||||
`pytest <https://pypi.org/p/pytest>`_ and
|
||||
`pytest-order <https://pypi.org/p/pytest-order>`_.
|
||||
|
||||
Install::
|
||||
|
||||
$ python3 -m venv .venv
|
||||
$ . .venv/bin/activate
|
||||
(.venv)$ pip install -e .[test]
|
||||
|
||||
Run::
|
||||
|
||||
(.venv)$ pytest -x

Change Log
|
||||
----------
|
||||
|
||||
1.0.1
|
||||
~~~~~
|
||||
|
||||
* officially remove Python 2 support that was broken since 1.0.0
|
||||
anyway; now the package works with Python 3.8+ because of a few
|
||||
features
|
||||
|
||||
1.0.0
|
||||
~~~~~
|
||||
|
||||
* significantly sped up execution on solid state drives by using
|
||||
a process pool executor to calculate SHA1 hashes and perform `stat()`
|
||||
calls; use `-w1` if your runs on slow magnetic drives were
|
||||
negatively affected by this change
|
||||
|
||||
* sped up execution by pre-loading all SQLite-stored hashes to memory
|
||||
and doing comparisons using Python sets
|
||||
|
||||
* all UTF-8 filenames are now normalized to NFKD in the database to
|
||||
enable cross-operating system checks
|
||||
|
||||
* the SQLite database is now vacuumed to minimize its size
|
||||
|
||||
* bugfix: additional Python 3 fixes when Unicode names were encountered
|
||||
