X-Git-Tag: submit/tizen/20240915.160017~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aaa4a11a9b0677b61a46b1b45f8c0e478ee9670b;p=platform%2Fframework%2Fweb%2Fchromium-efl.git

[VD] Correct the file format for startup tracing

Startup tracing usage:
1. Copy trace.config to /tmp of TV
2. Run the web browser or app:
/usr/apps/org.tizen.chromium-efl/bin/ubrowser --trace-config-file=/tmp/trace.config
3. Find the tracing result in /tmp/trace.json

Ref doc:
https://chromium.googlesource.com/chromium/src/+/lkgr/docs/memory-infra/memory_infra_startup_tracing.md

For WebBrowser chromium may be not able to access /tmp/trace.config,
you could put it into /opt/usr/apps/org.tizen.browser directory.

Sometimes WebBrowser can't write tracing result to /tmp,
you may find this log:
[ERROR:startup_tracing_controller.cc: Finalise(270)] Cannot move
file '/tmp/.org.chromium.Chromium.0RRXgP' to '/tmp/trace.json' :
FILE_ERROR_ACCESS_DENIED

In this case, '/tmp/.org.chromium.Chromium.0RRXgP' has the correct
tracing result inside.
