I20051130-1215

With the fix for bug 36032, we tried to remove our workaround for finding secondary types. It worked fine except for one problem. It seems to be a timing issue with updating the secondary type cache.

Steps:
- Set a breakpoint in JavaModelUtil#findType(IJavaProject, String) after the first return statement on the line
IPackageFragmentRoot[] roots= jproject.getPackageFragmentRoots();
(line 99 in rev 1.108 / I20051130-1215)
- debug UseSupertypeWherePossibleTests
=> The breakpoint should never be reached, but in testNew17(), the seconday type p.C is not found.

- While still hanging in the breakpoint, select the expression "jproject.findType(fullyQualifiedName)" and choose Run > Inspect.
=> Now, the type is found.

What's strange is that the type is also found when you just run testNew17() alone.

Comment 1 Frederic Fusier

Unfortunately, we won't be able to address this issue without huge performance hits. As it is currenlty designed, secondary types search relies on indexes contents and so, to get correct result, clients need to wait that these indexes are ready.
If we do it all the times, then we'll slow all other type search which do not really need it and this would not be acceptable.

So, the solution for this failing test is to call performDummySearch() after having created the cu...

Comment 2 Markus Keller

2005-12-01 08:39:36 EST

Hm, but then bug 36032 is not fixed for me. If clients have to do some dance like performDummySearch(), then you just move the burden to the client. If it's really not possible to find secondary types reliably in findType(String), then we maybe need another API findType(String fqn, boolean findSecondaryTypes) that clients can use.

The implementation could work like our current workaround:
First try to resolve as main type. If not found, wait for the index, then search again.

Comment 3 Frederic Fusier

2005-12-01 08:56:45 EST

Arglll do not say hat the bug is not fixed, after all the time I spent on this... ;-)
I would say that is fixed due to the fact that problem described in this bug and all duplicate ones are now addressed correctly.
You have found a unresolved scenario but it's not an usual one as no user got the same problem since 2 years and a half...

I agree that we can add another API to _explicitely_ wait for indexes and finally fix your problem => so I reopen this bug...

Comment 4 Frederic Fusier

2005-12-01 09:00:21 EST

This new API would be more findType(String fqn, IProgressMonitor monitor) which will wait for indexes _only_ if monitor is not null. This would give a chance to user to cancel in case indexing takes too much time...

Comment 5 Martin Aeschlimann

2005-12-01 09:50:11 EST

The API has to give a deterministic result. Finding a secondary type only when the search index happens to be up-to-date makes it hard to use this API.

I'm fine with an API that takes the IProgressMonitor. I don't like the suggestion that passing 'null' would not wait for the index. As said, the result should be deterministic. 'null' is normally a valid replacement of a NullProgressMonitor. We should not introduce a new notation here. Always waiting for the search index seems the right thing here.
If you don't want to force all clients into searching for secondary types, better introduce an extra boolean 'includeSecondaryTypes'
-> findType(String qualifiedName, boolean includeSecondaryTypes, IProgressMonitor)
The client can set this to false if he has more information of what he's looking for.

Comment 6 Frederic Fusier

2005-12-01 09:56:51 EST

OK, agreed that null for monitor was not a good idea.
Current API will do thta: ie. just return the content of existing cache and never wait if not thre or indexes not ready.
New API method will, instead, _always_ wait for indexes if cache not is there. If null is given for monitor, it will only signify that client does not need a way to cancel this operation...

Comment 7 Martin Aeschlimann

2005-12-01 10:10:09 EST

I'm concerned that we get random test failures if you implement to never wait for the index with the old code.

The thought the old API specified that it wouldn't find secondary types. Why not keep it that way?

Comment 8 Philipe Mulet

2005-12-01 10:16:04 EST

I like Martin suggestion for an extra flag. We also want a mode where we can quickly guess (and usually right) like when reconciling. Either the old API is the quick and dirty solution, or the new API provides a way to do so.

Comment 9 Markus Keller

2005-12-01 10:43:37 EST

I don't know in what scenarios clients would want to use the quick-and-dirty approach. Usually, they're either interested in secondary types all the time, or they don't care since they know that the type is a main type.

For JDT/UI, that would in most cases mean that we will call the considerSecondaryTypes version.

Comment 10 Frederic Fusier

2005-12-01 12:53:38 EST

I don't think additional flag is really necessary. If the problem is the fact that findType result may be not always the same as it can find secondary types or not, then we can just revert on 3.1 behavior and make this API method to _never_ consider secondary types.

Then, we add a new API method findType(String fqn, IProgressMonitor monitor) on IJavaProject which will _ever_ consider secondary types.

Both methods will have deterministic results and user can decide which one to use depending on his/her needs...

Comment 11 Martin Aeschlimann

2005-12-01 13:19:09 EST

comment 10 makes sense to me!

Comment 12 Philipe Mulet

2005-12-02 12:56:10 EST

To emphasize the need for reconciler to obtain fast answer for secondary types (even if not optimal until the indexing is finished), here is an example of VM dump obtained when moving workspace to latest I-build, and after importing all binary projects, and a couple minutes after build is finished, indexing is still really busy then I performed a source cleanup action, which got blocked with no visual clue (waiting on indexing ...). After 5 min. at same point, it still doesn't show any progress...

Comment 13 Frederic Fusier

Fixed and released in HEAD.

To summarize changes:
1) IJavaProject API methods findType(String), findType(String,WorkingCopyOwner), findType(String,String) and findType(String,String,WorkingCopyOwner) have been reverted to 3.1 behavior (ie. they do _not_ find secondary types).
2) 4 new corresponding API methods have added on IJavaProject which find 
   secondary types:
    - findType(String, IProgressMonitor)
    - findType(String, WorkingCopyOwner, IProgressMonitor)
    - findType(String, String, IProgressMonitor)
    - findType(String, String, WorkingCopyOwner, IProgressMonitor)
  Note that these methods wait for indexes to be ready before return the answer.
  Then we have a deterministic result but which may be delayed for a while if
  indexes are not ready.

NameLookup findType public internal methods have been modified to consider secondary types or not as well as to wait for indexes or not. For obvious performance potential issues, all JDT/Core tools (eg. code assist, reconciler, etc.) consider secondary types now but do _not_ wait for indexes...

I run performance tests and didn't get noticeable regression.

No test case added, just modify existing ones as they did not longer work with old findType API methods...
