Comment on SPLimitedWebPartManager Memory Leak? by bryan

Ah, you’re right Adrian! When I looked earlier I just took a quick glance at Dispose() and noticed it still wasn’t cleaning it up, but you’re right, it’s no longer creating the instance inside of SPLimitedWebPartManager, instead it’s point to an instance created by SPWebPartManager, and SPWebPartManager cleans up the SPWeb object.

Thanks for the correction!

From what I’ve seen in the code, this is NOT a memory leak in SP2010.

These 2 fields are part of the SPLimitedWebPartManager class:

SPWeb m_web;
SPWebPartManager m_manager;

When Dispose() is called on SPLimitedWebPartManager, inside it calls m_manager.Dispose() which calls m_web.Dipose()

The m_web of the SPWebPartManager instance references the same SPWeb instance as the m_web of the SPLimitedWebPartManager instance.

In order to see that the 2 fields reference the same SPWeb instance, take a look at the way this m_web is opened inside SPWeb.GetLimitedWebPartManagerInternal. Later on is assigned to the m_web of a SPWebPartCollectionInitialState instance and in the end to the newly created SPWebPartManager instance.

It’s a bit hard to follow, but if you need more details about the entire flow, I could provide them to you.

From what I’ve seen, yes. I poked around in SPLimitedWebPartManager for 2010 and it still does not appear to close the SPWeb object that it opens up, so I would recommend still explicitly closing it. If anyone has seen differently in 2010 let me know!

Hey Bryan, here is my version I was working on when I stumbled upon your version (wasn’t sure how to get the log names). It’s made for sql server 2005. Also I don’t like cursors so they’re not here.
——————————————
declare @SQLString NVARCHAR(MAX), @dbName as nvarchar(255), @logName as nvarchar(255)
declare @dbList as table( dbName nvarchar(255),logName nvarchar(255), runStatus bit default 0)

–Populate table variable with all db names and all db log file names
insert into @dbList (dbName,logName)
SELECT a.name, b.name from sys.databases a join sys.master_files b on a.database_id = b.database_id
where b.type = 1 AND a.name not in (‘master’, ‘model’, ‘msdb’, ‘tempdb’,'distribution’)
order by a.name
–Loop over all db
while (exists(select * from @dbList where runStatus=0))
begin
–Get first available database
SELECT top 1 @dbName = dbName, @logName = logName from @dbList where runStatus = 0
–Prepare sql statement here
SET @SQLString =
N’ USE ‘ + quotename(@dbName) + N’ ; ‘ +
N’ DBCC SHRINKFILE(‘ + quotename(@logName) + ‘ , 1) ; ‘ +
N’ BACKUP LOG ‘ + quotename(@dbName) +’ WITH TRUNCATE_ONLY ;’ +
N’ DBCC SHRINKFILE(‘ + quotename(@logName) + ‘ , 1) ;’
–Execute
EXECUTE sp_executesql @SQLString
–Flag used database
update @dbList set runStatus = 1 where dbName = @dbName
end

Have you tried using the built in function quotename() for T-SQL?
It returns the input string a valid SQL Server delimited identifier. ie, with [ ]

Very useful script.
