| 1 | Here is a first short HowTo on how to locate memory holes in Singular: |
|---|
| 2 | 1.) Make sure you build with -DOM_TRACK=5 (e.g. use Singulart, Singularg). |
|---|
| 3 | 2.) Use system("mtrack", [<level>, [<filename>]]) to get a report about |
|---|
| 4 | unused memory, where |
|---|
| 5 | * 0 <= level <= 5 determines how many stackframes per not freed |
|---|
| 6 | address are printed (default is 5 -- 0 only prints a summary) |
|---|
| 7 | * <filename> is name of file where report should be output to |
|---|
| 8 | (defaults to stdout). |
|---|
| 9 | 3.) Runing 'regress.cmd -tt <level> file.tst' creates the file |
|---|
| 10 | 'file.mtrack.unused' with report of not freed addresses (<level> has |
|---|
| 11 | same meaning as above). |
|---|
| 12 | 4.) Within the C/C++ sources, Use 'omMarkAsStatic(addr)' to mark an |
|---|
| 13 | address as static, i.e. as an address which is ok if it is not |
|---|
| 14 | freed. Addresses marked this way are not reported by |
|---|
| 15 | system("mtrack",...) (resp. regress.cmd -tt). |
|---|
| 16 | 5.) For some more details, see also extra.cc: system("mtrack", ...) |
