corruption

How do you determine if an .sqlite or .sqback is corrupt in Java?

由 為{幸葍}努か 提交于 2019-12-10 03:56:20
问题 I have been given a directory of directories each containing a collection of .sqlite and .sqback files that I must parse. The problem is that I believe some of these files to be corrupt when I receive them because I get the error: ERR: [SQLITE_CORRUPT] The database disk image is malformed (database disk image is malformed) on my console when I try to process them. This only happens with some of the files. I have isolated a few and tried running my program on fresh copies of these bad files

RStudio R File Corruption

问题 I had a R script open in RStudio. The file was saved many times over the course of several weeks and worked perfectly fine when RStudio was opened and closed. However, today, I restarted my computer and when I opened RStudio and more specifically the script that I mentioned, all of the R code vanished, leaving a single long row of "....." with red highlighting. When I tried to open the R file in other text processors such as Sublime Text and Notepad++, only a line of zeroes was visible. None

zlib decompression in python

由 旧巷老猫 提交于 2019-12-09 09:13:32
问题 Okay so I have some data streams compressed by python's (2.6) zlib.compress() function. When I try to decompress them, some of them won't decompress (zlib error -5, which seems to be a "buffer error", no idea what to make of that). At first, I thought I was done, but I realized that all the ones I couldn't decompress started with 0x78DA (the working ones were 0x789C), and I looked around and it seems to be a different kind of zlib compression -- the magic number changes depending on the

Android - reading a text file from Assets seems to include a LOT of junk before/after the actual data?

由 蓝咒 提交于 2019-12-08 02:51:04
问题 I package a text file with my Android App (in Assets) which I read within the App itself. To avoid this file being compressed, it's named 'mytestfile.mp3' and until recently, that worked just fine. In one of the recent SDK/ADT changes, it seems something 'odd' is happening when reading from Assets and I'm open to ideas as to what it is... I use code something like this AssetFileDescriptor descriptor = getAssets().openFd("mytextfile.mp3"); BufferedReader f = new BufferedReader(new FileReader

Visual Studio 2015 Debugger Corruption - Is it a bug or just me?

由 [亡魂溺海] 提交于 2019-12-06 01:38:51
问题 Have I gone mad? I've always been able to trust the debugger right? Turns out that during a debugging session with VS2015, when I for example change the value of a variable in the Immediate Window, then that assignment results in a "garbage" value being assigned. It's the same garbage value every time, but completely wrong nonetheless. I've distilled this down to the simplest console application repro, and just in case you might think to concur with my self-assessment of madness, I've also
