This tool allows interactive analysis of the statistics file created by
documents_statistics::DumpSandboxFileStatistics
.
To generate a report, enable the switch within the system Settings app.
Settings > Chrome Canary > Experimental Settings > Dump Sandbox File Statistics to Documents
then re-launch Chrome. A report will be placed within the
Application's Documents directory inside the sandboxFileStats
directory.
NOTE: This option is intentionally NOT generally available on Stable. It
requires a build with the ios_enable_sandbox_dump
arg enabled, which is
usually enabled for Canary/Dev builds.
In order to analyze the report, you need to copy it from your device to your computer (where this directory resides locally) using either of the following methods:
- You can access this file from the iOS Files app by navigating to
Files > Browse > On My iPhone > Chrome Canary > sandboxFileStats
. Then use any of the share sheet options to send the file via a means accessible on your computer. - Connect your iOS device to the computer via USB. (Be sure to "Trust" the
computer if prompted.) Navigate to Finder and select your iOS device from
the sidebar. ("Trust" the device in Finder if necessary.) Select the "Files"
tab, then expand the Chrome Canary app item. Drag the
sandboxFileStats
directory onto your computer in a discoverable location.
To inspect a report, open ./viewer.html
in your desktop browser.
The viewer only uses the files viewer.html
, viewer.css
, and tsc/viewer.js
.
Do not edit the JavaScript file directly, but rather edit viewer.ts
and then
generate the JavaScript file by running ./compile_typescript.py
from this
directory. Commit the generated file along with the modified JavaScript source
to allow for immediate use of this viewer without the need for the user to
compile the TypeScript.
