Mikhail Khludnev updated SOLR-4085:
-----------------------------------
Attachment: SOLR-4085.patch
added spin on race between lazy file loading and reload request. not absolutely
accurate, and efficient, but should be reliable enough. see
testSearchReloadRace. now race looks like (it's a test log)
{noformat}
oassf.FileFloatSource.getFloats Loaded external value source
external_test_make_a_pause_SOLR_4085_extf
oassf.FileFloatSource$ReloadFieldRequestHandler.handleRequestBody reloading
field test_make_a_pause_SOLR_4085_extf
oassf.FileFloatSource$Cache.resetAllReaders WARNING concurrent lazy loading
while reloading field: FileFloatSource.Key
[field=test_make_a_pause_SOLR_4085_extf .. file will loaded again
oassf.FileFloatSource.getValues WARNING concurrent reload detected. load file
again FileFloatSource.Key [field=test_make_a_pause_SOLR_4085_extf
oassf.FileFloatSource.getFloats Loaded external value source
external_test_make_a_pause_SOLR_4085_extf
{noformat}
race detection has a false positive case, which can be easily fixed. see
comment at FileFloatSource.getValues().
