TortoiseSVN 1.4.0, Build 5629 - 32 Bit -dev & Subversion 1.3.0,
Win2K dual core CPU box.
Explore to drive with revisioned folder.
TSVNCache crawls.
Memory usage climbs as expected.
Browse back to MyComputer view.
Repeat above process to the same drive as before.
Memory usage climbs some more.
Repeat above process to the same drive as before.
Memory usage climbs some more.
Select whitespace in WC.
Press F5 .
Repeat above process to the same drive as before.
Memory usage does not climb this time.
Did some testing using a USB removable drive, marvelous thing really.
Connected drive and Windows autorun feature pops up an explorer view of
first partition.
Selecting and moving Explorer vertical scrollbar prompts TSVNCache to
crawl newly revealed folders.
In TaskManager the cache memory usage climbs a bit.
Use windows "Unplug" process and note that cache memory usage does not
decrease as indicated by TaskManager.
Repeat above process.
Memory usage climbs some more but not a lot in % terms.
Repeat above process
Memory usage climbs some more but not a lot in % terms.
Copy a WC onto the USB drive.
Memory usage climbs some more but not a lot in % terms.
Delete WC. (7000+ files, 1300+ Folders)
Memory usage indicated in TaskManager does not decrease.
Memory allocated did not rise above 19MB.
There still appears to be a small, but less threatening leak still
occurring. Sorry I cannot be more specific.
This behavior memory use behavior is similar to a problem I encountered
in Delphi, where space allocated to strings that are not set back to
empty, (deliberate leak) is not released by the memory manager while the
var remains in scope. This is the expected behavior.
However the space is re-used the next time a same sized string is
allocated to that var. You don't get two separate leaks.
Don't know if that applies to C++, it's just seems a similar sort of
behavior going is on here after deleting the WC and then re-copying it
onto the drive again.
