 26 | ## Motivation
 27 | I wanted to view call-graph for OS source (written in C, C++) that connected APIs within one layer and APIs across layers.
 28 | This helps in getting a bigger picture of the source code and makes understanding large code bases QUICK.
 29 | 
 30 | ## Input
 31 | Requires data from gdb to get nodes (functions) and edges (function 1 calling function 2).
 32 | 
 33 | ## Output
 34 | Di-graph showing relationship between functions across software layers, the "bigger picture".
 35 | 
 36 | 
 37 | # Usage 
 38 | 
 39 | There are two parts to the whole process:
 40 | 1. get data by runnning process under gdb
 41 | 2. process this data with gen_graph.py
 42 | 
 43 | 
 44 | ## Part I: Get data from GDB
 45 | 
 46 | ### Test code    
 47 | 
 48 | 	$  cat test.c
 49 | 	#include<stdio.h>
 50 | 	#include<stdbool.h>
 51 | 	#include<stdlib.h>
 52 | 	#include<time.h>
 53 | 	
 54 | 	
 55 | 	static void func9(void) { printf("leaf\n"); }
 56 | 
 57 | 	void func8(void) { func9(); }
 58 | 	
 59 | 	void func7_1(bool is_true, int *p) { printf("leaf (is_true=%d, ptr=%p\n", is_true, p); }
 60 | 	void func7(void) { func8(); }
 61 | 	
 62 | 	void func6(void) { func7(); }
 63 | 	
 64 | 	void func5_1(const char* str) { printf("leaf (%s)\n", str); }
 65 | 	void func5(void) {
 66 | 	    func5_1("graph me\n");
 67 | 	    func6();
 68 | 	}
 69 | 	
 70 | 	void func4(void) { func5(); }
 71 | 	void func3_1(int a, int b, int c) { printf("leaf\n"); }
 72 | 	void func3(void) {
 73 | 	    func3_1(rand(), rand(), rand());
 74 | 	    func4();
 75 | 	}
 76 | 	
 77 | 	void func2_1(int a, int b) { printf("leaf (%d, %d)\n", a, b);}
 78 | 	void func2(void) {
 79 | 	    func2_1(rand(),rand());
 80 | 	    func3();
 81 | 	}
 82 | 	void func1(void) { func2(); }
 83 | 	int main()
 84 | 	{
 85 | 	    srand(time(NULL));
 86 | 	    for(int i=0; i<10; ++i) {
 87 | 	            func1();
 88 | 	    }
 89 | 	        return 0;
 90 | 	}
 91 | 
 92 | ### Enable debugging symbols    
 93 |     $ gcc -g test.c
 94 | 
 95 | ### Start binary under GDB     
 96 |     $ gdb a.out
 97 |     . . .
 98 |     Reading symbols from a.out...done.
 99 | 
100 | #### Insert breakpoints on functions of interest, or to put in every funtion in a file:    
101 | 
102 | 	(gdb) rbreak test.c:.
103 | 	Breakpoint 1 at 0x400786: file test/test.c, line 33.
104 | 	void func1(void);
105 | 	Breakpoint 2 at 0x400760: file test/test.c, line 30.
106 | 	void func2(void);
107 | 	Breakpoint 3 at 0x40073d: file test/test.c, line 28.
108 | 	void func2_1(int, int);
109 | 	Breakpoint 4 at 0x400704: file test/test.c, line 24.
110 | 	void func3(void);
111 | 	Breakpoint 5 at 0x4006f0: file test/test.c, line 22.
112 | 	void func3_1(int, int, int);
113 | 	Breakpoint 6 at 0x4006d7: file test/test.c, line 21.
114 | 	void func4(void);
115 | 	Breakpoint 7 at 0x4006c1: file test/test.c, line 17.
116 | 	void func5(void);
117 | 	Breakpoint 8 at 0x4006a4: file test/test.c, line 15.
118 | 	void func5_1(const char *);
119 | 	Breakpoint 9 at 0x400690: file test/test.c, line 13.
120 | 	void func6(void);
121 | 	Breakpoint 10 at 0x400684: file test/test.c, line 11.
122 | 	void func7(void);
123 | 	Breakpoint 11 at 0x400664: file test/test.c, line 10.
124 | 	void func7_1(_Bool, int *);
125 | 	Breakpoint 12 at 0x40064b: file test/test.c, line 8.
126 | 	void func8(void);
127 | 	Breakpoint 13 at 0x400796: file test/test.c, line 36.
128 | 	int main();
129 | 	Breakpoint 14 at 0x40063a: file test/test.c, line 7.
130 | 	static void func9(void);
131 | 
132 | #### Enable logging
133 |     (gdb) set pagination off
134 |     (gdb) set print pretty
135 |     (gdb) set logging file ./test.log
136 |     (gdb) set logging on
137 |     Copying output to ./test.log.
138 | 
139 | #### Tell gdb to print backtrace and continue without asking when it hits  a breakpoint    
140 |     (gdb) command
141 |     Type commands for breakpoint(s) 1-10, one per line.
142 |     End with a line saying just "end".
143 |     >bt
144 |     >c
145 |     >end
146 | 
147 | 
148 | #### Start  the program    
149 |     (gdb) r
150 |     Starting program: /home/vagrant/c_code/a.out
151 | 
152 |     Once the program finishes, it would have dumped the logs to the disk in test.log    
153 | 
154 | 
155 | ## Part II: run gen_graph.py on collected data
156 | 
157 | ### Dependencies    
158 | 
159 |     sudo apt-get install graphviz
160 |     sudo python3 -m pip install -r requiments.txt
161 | 
162 | 
163 | ### Run gen_graph.py    
164 |     $  python3 gen_graph.py
165 |     usage: gen_graph.py [-h] -i INPUT_FILE [-f {gdb,objdump}]
166 |     gen_graph.py: error: the following arguments are required: -i/--input_file
167 | 
168 |     $  python3 gen_graph.py -i test/test.log
169 | 	01/02/2021 08:36:58 PM [1] processing gdb bt data
170 | 	01/02/2021 08:36:58 PM [2] adding nodes, edges, #ofnodes=13
171 | 	01/02/2021 08:36:59 PM [3] Embedding JS
172 | 	01/02/2021 08:36:59 PM [4] saving graph to:
173 | 	01/02/2021 08:36:59 PM       /home/vagrant/dwnlds/gdb_graphs/test.svg
174 | 	01/02/2021 08:36:59 PM Finished
175 |  
176 | 
177 | Open the svg file in a browser
178 | ![Alt text](gallery/test.png?raw=true "")
179 | 
180 | 
181 | ## New 
182 | - Interactive graphs:
183 |   Click on a node and entire parent and child chain is highlighted
184 |   (to reset -  reload page - untill I find a better way to do from JS)
185 | - C++ Support
186 | - Node tooltip shows function arguments (max 6)
