|
This directory contains tools to automatically get data about the memory consumption by some objects in dashd process with the help of GDB debugger.
|
|
|
|
## dash_dbg.sh
|
|
This shell script attaches GDB to the running dashd process (should be built with debug info), executes debug.gdb script and detaches.
|
|
By default it uses testnet settings, see script comments to attach it to mainnet dashd.
|
|
|
|
## debug.gdb
|
|
Contains debugger instructions to execute during attach: loads python code and executes it for the objects we want to investigate.
|
|
|
|
## log_size.py
|
|
Contains definition of the gdb command log_size. After this script loads it can be called from gdb command line or other gdb scripts.
|
|
Command params:
|
|
`log_size arg0 arg1`
|
|
`arg0` - name of object whose memory will be written in log file
|
|
`arg1` - name of the log file
|
|
Example:
|
|
```
|
|
log_size mnodeman "memlog.txt"
|
|
```
|
|
|
|
## used_size.py
|
|
Contains definition of the gdb command used_size. After loading of this script it can be called from gdb command line or other gdb scripts.
|
|
Command params:
|
|
`used_size arg0 arg1`
|
|
`arg0` - variable to store memory used by the object
|
|
`arg1` - name of object whose memory will be calculated and stored in the first argument
|
|
Example:
|
|
```
|
|
>(gdb) set $size = 0
|
|
>(gdb) used_size $size mnodeman
|
|
>(gdb) p $size
|
|
```
|
|
|
|
## stl_containers.py
|
|
Contains helper classes to calculate memory used by the STL containers (list, vector, map, set, pair).
|
|
|
|
## simple_class_obj.py
|
|
Contains a helper class to calculate the memory used by an object as a sum of the memory used by its fields.
|
|
All processed objects of such type are listed in the this file, you can add new types you are interested in to this list.
|
|
If a type is not listed here, its size is the return of sizeof (except STL containers which are processed in stl_containers.py).
|
|
|
|
## common_helpers.py
|
|
Several helper functions that are used in other python code.
