corruption

问题 I am using carrierwave to upload images to amazon s3. This works great on development, but not when I push it to my server (engineyard cloud trial). The process works fine, no errors are thrown, and a link is given back. However, the actual image is corrupted, somehow. Here's one, for example: https://s3.amazonaws.com/ZenBucket/uploads/goal/photo/30/guinness-toucan.jpg Can anyone tell me how it's being corrupted, or what could be doing it? Edit: The first image upload attempt after deploying

问题 I just went to clone a repository on another remote server and ran into an issue trying to do so: git clone git@codebasehq.com:blah/blah/docs.git Cloning into docs... remote: Counting objects: 343, done. remote: error: unable to find 14f87a739828e4d489b0310a51e057b30333926e remote: Compressing objects: 100% (325/325), done. error: git upload-pack: git-pack-objects died with error. fatal: git upload-pack: aborting due to possible repository corruption on the remote side. remote: fatal: unable

问题 Suppose there is a bug in a Java Card applet: a temporary byte array is stored in EEPROM instead of RAM. Moreover, suppose this byte array is overwritten with each APDU. This bug should damage the card sooner or later. What symptoms could we expect? Incorrect values in the array without any explicit warnings or errors? Some exceptions thrown when accessing this array? The applet unselectable? The whole card completely unresponsive? Should the card be damaged "once and forever", or will these

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last month . Why am I getting the message "Not a JPEG file: starts with 0x89 0x50" when I try to open my jpg file? 回答1: The file is actually a PNG with the wrong file extension. "0x89 0x50" is how a PNG file starts. 回答2: Your file is not a JPEG file, it's just been renamed from a PNG to a JPEG somewhere along the way. Some

问题 In C++, in which way the stack may get corrupted. One way I guess is to overwriting the stack variables by accessing an array beyond its boundaries. Is there any other way that it can get corrupted? 回答1: You could have a random/undefined pointer that ends up pointing to the stack, and write though that. An assembly function could incorrectly setup/modify/restore the stack Cosmic waves could flips bits in the stack. Radioactive elements in the chip's casing could flip bits. Anything in the

问题 This is a follow up question to a previously answered post: Is there a command line utility for validating SQLite databases in Linux? If a database is producing the following error: $ sqlite3 mydata.db "PRAGMA integrity_check" Error: database disk image is malformed Is there any cleanup processing that can be done to recover the database to a usable state? Even at the potential loss of some corrupt records? Thanks 回答1: If there were any automatic method, SQLite would already be able to do it.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I get the following error when running a c program: *** Error in `./a.out': double free or corruption (!prev): 0x0000000000bb0470 *** I believe this is due to fclose() being called in the program, It is a Lexical Analyzer for compilers in c language and it uses file pointers . Here is code: #include<stdio.h>

问题 Since Mongo doesn't have transactions that can be used to ensure that nothing is committed to the database unless its consistent (non corrupt) data, if my application dies between making a write to one document, and making a related write to another document, what techniques can I use to remove the corrupt data and/or recover in some way? 回答1: The greater idea behind NoSQL was to use a carefully modeled data structure for a specific problem, instead of hitting every problem with a hammer.

问题 I have a fairly simple piece of code which launches a QProcess: launchResultCode = ELaunchOk; QDateTime beginTimeStamp = QDateTime::currentDateTime(); command->start(commandpath, myParameters); if (command->waitForStarted(waitToStart)) { if (!myStdIn.isEmpty()) command->write(myStdIn.toLatin1()); command->closeWriteChannel(); qDebug() << "P1"; if (command->waitForFinished(waitToFinish)) { myStdOut = command->readAllStandardOutput(); myStdErr = command->readAllStandardError(); } else {
