1 memory_watcher is a library that can be linked into chromium to trace the

2 memory allocations. It works by hooking the system allocation/deallocation

3 functions, and recording the actions.

4

5 To use memory_watcher in chromium:

6

7 (1) Compile the memory_watcher library (it is part of the solution by default)

8

9 (2) Run chromium with these flags "--memory-profile -no-sandbox"

10 (The instrumentation doesn't work with the sandbox)

11

12 (3) Hit ctrl-alt-D to generate a dump of the memory allocations.

13 This will create a log file called memorywatcher.logXXXX for every

14 chromium process (where XXXX is the pid).

15

16 The log file is a human readable text format, which can be further analyzed

17 using the helpers in the "scripts/" directory.
