Re: [Bacula-users] About Bacula's Windows client

Hello,

I have been study bacula's source code yesterday. And I find that the BackupWrite API would be used wrong.

In msdn, this API's describe says that this function allocates memory for the IpContext data structure, and then sets the variable to point to that strucure. To release the memory used by the data structure, call BackupWrite with the bAbort paramter set to TRUE when the restore operation is complete.

I find that bacula seems just to use bwrite() function to write and not call this API again when restore finished.

I think that just adding this API with setting bAort and IpContext paramters when the restore operation is complete will solve this problem.

Best regards

That indeed looks like a bug.

Wether is is in the FD or Windows' API is not easily determined.

I suggest you file a bug report with some more details (Bacula and OS

version, memory usage statistics and output from 'status client=' to

clearly show the problem.

Note that it can take a while before this bug would be processed -

Kern is on vacation, and I'm not sure we have any windows-gurus among

the developers.
