Description Jan Becicka 2011-01-30 20:37:57 UTC 
full ide

  Product Version         = NetBeans IDE Dev (Build 110130-7ae8dd573ee3) (#7ae8dd573ee3)
  Operating System        = Mac OS X version 10.5.8 running on x86_64
  Java; VM; Vendor        = 1.6.0_22; Java HotSpot(TM) 64-Bit Server VM 17.1-b03-307; Apple Inc.
  Runtime                 = Java(TM) SE Runtime Environment 1.6.0_22-b04-307-9M3263


I tried to do some perf. testing, but I failed.
I started fresh build, with fresh userdir and I tried to open attached project.
I did 3 attempts and all failed. I tried to open very same project with 6.9.1 and it works.

project file is located at http://www.uloz.to/7636820/lime6-zip
Comment 3 Jan Becicka 2011-01-31 14:40:14 UTC 
works for me with today's build. Not P1 any more.
Comment 4 Jesse Glick 2011-01-31 16:03:40 UTC 
I think the issue is FileUtil.holders vs. masterfs mutex, though I cannot see what code is inside that mutex - something in "Parsing & Indexing Loop" I presume. The question is probably whether HgUtils.isIgnored really needs to synchronously check SharabilityQuery.getSharability.
Comment 5 Jaroslav Tulach 2011-01-31 22:10:58 UTC 
Calling 

	at org.netbeans.modules.masterfs.ProvidedExtensionsProxy.beforeCreate(ProvidedExtensionsProxy.java:148)
	at org.netbeans.modules.masterfs.filebasedfs.fileobjects.FolderObj.createData(FolderObj.java:332)

with lock is probably the source of the problem.
Comment 6 Tomas Stupka 2011-02-01 13:43:56 UTC 
on the other hand, like Jesse pointed out, a synchronous sharability check in mercurial should be avoided.
