Crashpad and omaha work

[Nhan Nguyen]

Hi,

Crashpad is replacing breakpad from chromium 49.

Does it affect to omaha works?

Chrome switching to Crashpad does not affect at all how Omaha works.

Omaha will also use Crashpad at some point but the timeline for this change is not defined at this time.

One more question,

What is the relationship of breakpad and crashpad on windows? 
Crashpad is now running as a separated process, it collects crash report then sends to omaha, a breakpad hosting, or sends to breakpad then breakpad continues sending crash report to omaha? Shortly, Crashpad -> omaha, or Crashpad -> breakpad -> omaha? 
I prefer the first option (crashpad-> omaha) to 2nd option (crashpad -> breakpad -> omah), because the omaha opens a pipe for crashing report as a breakpad server, but the question is: The breakpad hosting (Omaha) accepts crash report from Crashpad, doesn't it?

Hi,

So, what is the relationship between Crashpad process, browser process with breakpad inside and omaha?

What is the life circle of a crash report generated by Crashpad on windows?

Crashpad is the next generation of crash handling client, it is intended to be an improved Breakpad. Please see here the original

The latest Chrome builds don't use Omaha anymore for crash handling. Crashes in Chrome are handled by a Chrome and uploaded to the crash backend. Crashpad has no dependency on Breakpad. It is a standalone library.

At this time, Omaha does not support Crashpad.

Crashpad is used to handle crashes in the latest builds of Chrome. At this time, there is no relationship between Crashpad and Omaha, but the intention is for Omaha to start using Crashpad to handle its own crashes, but not Chrome crashes.

When a crash occurs in the target process, Crashpad gets activated out of process, and creates a dump. If it is allowed to upload the dump,  Crashpad uploads it to the crash server. Once on the crash server, the dump is analyzed and indexed, so it can be queried and inspected. There is a retention policy associated with crashes which deletes older dumps.

Hi Sorin,
Nice to have your support.
So at the end, the crashpad sends (uploads) the crash report (browser dump) directly to crash reporting server - It works that way on the latest build of chrome? 
And in the future, crashpad will become a part of omaha as a crash reporter of omaha dump?

That is my understanding yes. I am not sure if the change made it to the stable channel, but at any rate, Chrome is definitely going to be using Crashpad on the platforms where Crashpad is available.

Correct. That is the intention.

Thank Sorin once again,
I got the crashpad working mechanism.
Hope this topic will help crashpad and omaha users :).
