java - Hibernate Search synchronous execution in main thread -

-

Text after "

It looks like Hibernate Search uses synchronous execution other formulas other than calling thread for parallel execution.

How? I execute hanging serial search hibernate sequence in the thread

Problem in being the org.hibernate.search.backend.impl.lucene.QueueProcessors class looks: 

  Private zero runoff () throws blocking exceptions {list & lt; Future & lt; Object & gt; & Gt; Futures = New Arrestist & lt; Future & lt; Object & gt; & Gt; (DPProcessor size ()); // Perform all the tasks in parallel on each directory provider; // Each DP has its own Executioners service. (PerDPQueueProcessor Process: dpProcessors.values ​​()) {Executor Services Exporter = process.getOwningExecutor (); // Wrap every runner in every future future & lt; Object & gt; F = new futuristic & lt; Object & gt; (Process, empty); Futures.ed (F); Executor.execute (f); } // And then wait for all tasks to be completed: For (future  gt; f: futures) {if (! F.isDone ()) {try {f.get ()}} Grip (ignore cancellationException ignore) {// ignored as, java.util.concurrent.AbstractExecutorService.invokeAll (collections of & lt; repayable & lt; t & gt; & gt; // functions)} (ExecutionException error) {// Reithrow reason to thread threading - This can hide more exceptions: Throwable Cause = Error. Gel reason (); New search exception throw (reason); }}}}   
 A serial synchronous execution will reveal what the thread will be in thread and disclose reference information such as the authentication information for the underlying DirectoryProvider. 
  
  "itemprop =" text "> 
 is a very old question, but I can also answer it ... 
 < P> Find Hibernate to make a single threaded access to Lucene  IndexWriter  (which is required by Lucene) for a directory. I had a way of dealing with queue problem using a single threaded executor of per-directory imagery. 
 
 If you want to run all this in the thread, then you need to re-apply the code> LuceneBackendQueueProcessorFactory  and in the hibernate properties  hibernate.search.worker.backend < Bind to / code>. Not trivial, but tax-worthy.

windows - Heroku throws SQLITE3 Read only exception -






-















    After I deploy the app to Heroku, I have to run migration scripts and get this error message    ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init '    how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work      Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads.   I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -






-















    I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java   The input to the lexical analyzer is a .tex file that is of the following format.    \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document}    The output of the lecture may be a table of contents with a page number in another file.    1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of  Language Analysis     Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning.   I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -






-















    I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly.   For example, my keys are like this:    '1', '101', '11'    and I may need them:    '001', '101', '011'    What is doing, but I know that there is a better way    tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict       You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction.    for sorted (D, key = int): print '% s:% R'% (k, d [k])   < / Div>
