in-memory

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 2 years ago . I am currently using DB2 to do unit tests, but it is sometime quite slow. I would need a good in-memory database that would include all the feature of DB2. Does this type of in-memory database exist, or do they only allow standard SQL feature? Thank you. EDIT The DB2 Database is on a remote server, so I would

问题 Is there any way of detecting that a debugger is running in memory? and here comes the on Form Load pseudocode. if debugger.IsRunning then Application.exit end if Edit: The original title was "Detecting an in memory debugger" 回答1: Try the following if ( System.Diagnostics.Debugger.IsAttached ) { ... } 回答2: Two things to keep in mind before using this to close an application running in the debugger: I've used a debugger to pull a crash trace from a commercial .NET application and send it to

问题 I've been reading, browsing, searching a lot on this, I've criss-crossed stackoverflow back and forth many times and I managed to narrow my problem as much as I could. The only thing I do not understand, is how to fully use an in-memory SQLite database. Here is my situation - I have an encrypted SQLite database which I decrypt during the loading of my application (this part works for sure). My class that interacts with the database works for sure with a plain database. So to make it short,

问题 i'm having some issues getting the .Filter() method to work in subsonic, and i'm constantly getting errors like the one below: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Line 36: bool remove = false; Line 37: System.Reflection.PropertyInfo pi = o.GetType().GetProperty(w.ColumnName); Line 38: if (pi.CanRead) Line 39: { Line 40: object val = pi.GetValue(o, null); i'm making calls like the one below- is this the corrent way to use it?

问题 I'm using scikit-image to read an image: img = skimage.io.imread(filename) After doing some manipulations to img , I'd like to save it to an in-memory file (a la StringIO) to pass off to another function, but it looks like skimage.io.imsave requires a filename, not a file handle. I'd like to avoid hitting the disk ( imsave followed by read from another imaging library) if at all possible. Is there a nice way to get imsave (or some other scikit-image-friendly function) to work with StringIO ?

问题 I have installed HazelCast 2.5. I want to persist my records into disk. I learned that MapStore does this job. However i'm not sure how to implement MapStore. Code i've written so far: public class MyMaps implements MapStore<String,String> { public static Map<Integer, String> mapCustomers = Hazelcast.getMap("customers"); public static void main(String[] args) { { mapCustomers.put(1, "Ram"); mapCustomers.put(2, "David"); mapCustomers.put(3, "Arun"); } } How do i put all these entries into disk

问题 I'm trying to use angular2 InMemoryWebApiModule and implement the InMemoryDbService, to create a mock-up of my backend server. I configured it as (I thought) it should be, but somehow I can't reach the data structure that implement the InMemoryDbService (WorkerData in worker.ts) and keep getting status 404 ("Collection 'workers' not found"). I've simplified the code to make it clearer. This is a URL issue - can't figuring out why. The problem occurs when executing the getWorkrs function in

问题 I'm working on a web app that needs to create GPG signatures for files as they're uploaded by someone on staff. However, for security, I don't want to keep the signing key on the webserver, even though it's protected by a passphrase. One solution I was looking into was to prompt for the private key on startup of the webapp, and store it in memory. Then, pass in the text of the key when signing, instead of using a key from the keyring. However, I've done a lot of looking around and can't find

问题 I want to zip a string(could be very big) and send it through FTP. So far I am using ftplib and ziplib, but they are not getting along too well. ftp = FTP(self.host) ftp.login(user=self.username, passwd=self.password) ftp.cwd(self.remote_path) buf = io.BytesIO(str.encode("This string could be huge!!")) zip = ZipFile.ZipFile(buf, mode='x') # Either one of the two lines ftp.storbinary("STOR " + self.filename, buf) # Works perfectly! ftp.storbinary("STOR " + self.filename, zip) # Doesnt Work ftp
