Memory Leaks

OTcl

OTcl, in particular TclCL, offers the ability to assign new objects,however, it does not subsequently provide garbage collection.The mechanism for these consumables. This can be easy tooinvoluntary retention leaks.Important: clean up tools like dmalloc and thereforecannot detect these types of memory leaks.For example, consider this simple OTcl script:

 set ns [new simulator]for the set i 0 {$ iYou expect most of the memory usage to be used afterthe first random variable is assigned. But due to the fact that OTcl does not haveGarbage collection, when a second random variable is usually assigned,the previous one cannot be released and therefore results in a review leak.Unfortunately, there are simply no indications. for this, because rubbishCollecting designated devices is inherently incompatible withSpirit of Tcl. The only way to solve this problem at the moment is alwaysExplicitly share every OTcl object assigned in your script tothe same approach you use for unallocated C / C ++ articles.

C / C ++

Another source is a memory leak in C / C ++. It’s too muchkeep track of predefined tools primarily designed for this task, for example.dmalloc and clean.Ns has a special target ns-pure to be able to create purified nsexecutable file. First make sure who is using the macro. In clear ns Makefile has a suitable builder for your. didLinker (see the Detoxify man page if you’re not sure what it is).Then just type make ns-pure .See how to use ns with libdmalloc here.

Tcl-level Debugging

Ns supports Don Libs Tcl debugger(seePostScript DocumentationandSource).Install an alternative program and leave the source code therethe site is parallel to NS-2 and it will be built.different from what is described in the tcl debug documentation,we couldn’t stand it-D Flag. To enter theA debugger that chooses “debug 1” in your script all the way throughappropriate place.

$ ns gen-map command lists all properties in raw form.

This is usefulreference to the position and function of the large object.given his name.The part name is an OTcl pen, usually shaped like a mold.“ _o ### ”.For TclObjects, this is also available in a C ++ debugger such as gdblike this-> name_.

C-level Debugging

Every standard debugger has to do a certain trick.

The following macro for gdb makes it easier to see what’s going on inRoutines take Tcl arguments (for example, TcpAgent :: command ()):

Mix Tcl And C Debugging

(Still an interesting concept, right?)

This is probably a painful reality when tcl code and debugging is in the marketTcl level things, you want to reach the most important C level classes and vice versavice versa. This is also a small hint on how you can simplify this task.if ns is powered by GDB then
