1883747 - Add disk size measurements for a miscellaneous bag of data stores

Status: RESOLVED FIXED

(Firefox :: Profile Backup, task, P3)

Description

[Mike Conley (:mconley) (:⚙️)]

There's some shared infrastructure here with bug 1883642 (for the metrics.yaml file, for setting up the private method in BackupService that does measurement, and for test infrastructure).

This is the set of things to measure the size of:

• times.json
• The summed size of all files ending in .sqlite under storage/permanent/chrome
• signedInUser.json
• enumerate_devices.txt
• protections.sqlite
• SiteSecurityServiceState.bin

Removed ExperimentStoreData.json from the list - according to our experimenter folk, we definitely don't want to have that cloned between machines.

• The summed size of all files ending in .sqlite under storage/permanent/chrome

Rather than addressing all IndexedDB-related measurements in this bug, let's work on it instead in this follow-up ticket that Fred filed recently: Bug 1887724.

Data collection request

data-review+

I'd suggest mentioning in the measurement description that the data is rounded off / fuzzed to the nearest 10Kb.

---

1. Is there or will there be documentation that describes the schema for the ultimate data set in a public, complete, and accurate way?

Yes.

2. Is there a control mechanism that allows the user to turn the data collection on and off?

Yes, the usual Firefox data collection opt-out.

3. If the request is for permanent data collection, is there someone who will monitor the data over time?

Yes, mconley will monitor.

4. Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, technical data.

5. Is the data collection request for default-on or default-off?

Default on.

6. Does the instrumentation include the addition of any new identifiers (whether anonymous or otherwise; e.g., username, random IDs, etc. See the appendix for more details)?

No.

7. Is the data collection covered by the existing Firefox privacy notice?

Yes.

8. Does the data collection use a third-party collection tool?

No.
