Version 5 of Why does Tcl leak memory?

Updated 2005-07-21 16:34:15

It doesn't, with rare exceptions.

[Details.]

TCT takes memory leaks [ref] very seriously. Few ever escape into a release, and few known ones survive long.

However, there are at least an order of magnitude more perceived memory leaks. These result mainly from two causes:

• mis-measured memory use
• userland, or application-level, memory leaks.
• not cleaning up Tcl global vars such as the http package token returned from a getURL.
