            How to detect shutil.copytree is done copying?
            Asked 2021-Jun-15 at 13:30

            I use python 3.8 on archlinux. I use shutil.copytree to copy a folder into a usb key. When i check into the usb after copy, the folder is correctly copied, but i see that my usb key that has a ticking led is still writing. If i eject my usb key before the ticking is over and reconnect it, i see that the folders are not entirely copied. Means that my OS (archlinux) thinks that the copy is done, but it's not. Any ideas ?

            ANSWER

            Answered 2021-Jun-15 at 13:30

            It seems like the copy has logically finished, but hasn't been fully written to the physical USB flash drive. That is to say, your OS has cached some of the data from the copy, and will actually write it to the drive at a later time, but definitely before the drive is unmounted.

            To check if this is the case, you can check (either within Python or through some other program) if the copy has completed once the code has moved on past shutil.copytree. If it has, then the issue is almost certainly that the USB flash drive was not safely ejected.

            You should be able to solve this by unmounting (i.e. safely ejecting) the USB flash drive before removing it.

            You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:

            ANSWER

            Answered 2021-Jun-03 at 20:36

            You issue could well be that the database is using WAL (Write-Ahead logging) as opposed to journal mode.

            With WAL changes are written to the WAL file (database file name suffixed with -wal and also another file -shm). If the database hasn't been committed and you only backup/restore the database file. You will lose data.

            • When fully committed, the -wal file will be 0 bytes or not exist, in which case it is not needed.

            From Android 9 the default was changed from journal mode to WAL.

            Assuming that this is your issue you have some options:-

            1. Use Journal mode (e.g. use the SQLiteDatabase disableWriteAheadLogging method)
            2. Backup/Restore all 3 files (if they exist)
            3. Fully Commit the database and then backup (closing the database should fully commit) and delete/rename the -wal file and -shm file before restoring.

            Option 3 would be the recommended way as you then gain the advantages of WAL.

            Here's an example of fully checkpointing (a little over the top but it works):-

            How does SASL_SSL security protocol work? Does client verify the server (X.509 cert)?
            Asked 2021-Jun-13 at 15:43

            How SSL works is well know as it's quite widely used and described well every where. In short - SSL involves

            1. Verifying server authenticity by client by verifying the servers X.509 certificate.
            2. Then arriving at a symmetric key using diffie-hellman key exchange algorithm.

            But I am not sure what happens withsecurity.protocol=SASL_SSL. Clients and Server communication of few technologies like Kafka etc rely on this security protocol as one of the option. Here I am worried about the point 1 above. If i get a wrong broker address (as a trick ) from some one, does SASL_SSL verify the server certificate or not is my question. If it does, then I can be sure that the received broker is not genuine and my application will not publish or subscribe to messages from this server and my data is safe.

            Edit 1: Following @steffen-ullrich answer and comments And little more dig, i see below. Looks like the certificate validation is happening when used through chrome and probably its loaded in the cacerts too. So the java code is able to authenticate the server.. so seems ok..

            Edit 2: Right the certificates DST and ISRG are preloaded in the JDK 11 cacerts, so the client is able to authenticate the server as commented by Stephen.

            With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution() states that:

            The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.

            So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

            We know that Shi-Tomasi is based on finding eigenvalues so there is even a function in OpenCV to calculate the minimal eigenvalue of gradient matrices for corner detection called cornerMinEigenVal in case you want to do your own implementation:

            Short answer: There is no such function in OpenCV that calculate MinEigenVals for sparse points. However, you can implement one from HarrisResponses() with just small modifications.

            The HarrisResponses() function is used to calculate Harris score for sparse points (it's static in OpenCV, so you can't call it directly).

            Look through the code of calcMinEigenVal() and calcHarris(), and you will find that the only difference between them is how they use values from the cov matrix:

            With some changes, I was able to fix your code and get it working on my computer.

            • Use strip() to remove the Windows style newline at the end of line and extra white space. This assumes that while your directory names might contain spaces, they won't end or start with a space.
            • Instead of doing chdir to source_path, I open it in place. This allows me to use relative paths instead of exclusively absolute ones, and there's really no need to change the dir anyway. As a result, the files in source_path are referred to via os.path.join(source_path, f).
            • Put a try/except around listdir to handle the case where the directory does not exist.
            • Test that dest_dir exists and is a directory, to avoid various problems.
            • I tested this script and it works on my Windows 10 machine with Python 3.9.5 called from PowerShell. It works with one or multiple lines, and the paths can use \\ or just \.
