concurrency - Neo4j-Neoclipse Concurrent access issue -

-

i creating few nodes in neo4j using spring data, , accessing them via findbypropertyvalue(prop, val).

everything works correctly when reading/writing embedded db using spring data.

now, per michael hunger's book : relationship, opened neoclipse in read-only mode connection active neo4j connection in java..

but, somehow still says neo4j's kernel actively used other program or something.

question 1 :what doing wrong here?

also, have created few nodes , persisted them. whenever restart embedded neo4j db, can view nodes when findall().

question 2 :when try visualize nodes in neoclipse(considering db accessible), can see one single node(which empty), has no properties associated it, whereas have name property defined.

i started java app, persisted few nodes, traversed , got output in java console. now, shutdown application , started neoclipse ide, connected db , found no nodes present(problem of question 2). after trying again(heads down), go java app , ran app, , surprisingly found getting lucene-file-corrupted error(unrecognized file format) error. had no code changes, did not delete anything, still got error.

question 3 :not sure doing wrong. since found this discussion on bug(lucene/concurrent db access), willing know if bug or if due programatic error.(does have eclipse juno)

any reply highly appreciated.

  1. make sure committing transactions.
  2. data not flushed disk neo4j , hence might not viewing nodes in neoclipse. restart application using neo4j in embedded mode data flushed disk , open neoclipse.

posting code check issues.

Line ending issue with Mercurial or Visual Studio -

i seem have strange issue caused either visual studio or mercurial. localised single project, i'm guessing in project configuration causing issue. at difficult specify point, when perform action in visual studio, update every line ending in given file, means when @ file in sourcetree, every line has changed. i can replicate using nuget add package dependency; packages.config entirely replaced. if commit changes, including line endings, later same issue occur. workaround have shelve changes , reapply them, whereupon lines written correctly. i'm not sure application blame here. did make mistake of allowing sourcetree change mercurial configuration, issue have fixed, i'm not sure if has persisted. i thought might issue mercurial.ini files or hgrcs don't seem contain untoward. here's mercurial.ini [ui] username = ....
