I tried to run clang-format-10 and the message that I get is:
You're using an old version of clang-format binary. Please update to a more recent one by running: './mach bootstrap'

It is because our version comparison is pretty bad:
https://searchfox.org/mozilla-central/source/python/mozbuild/mozbuild/code-analysis/mach_commands.py#919

We could either:

• improve the version detection
• fix the wording to force only one version

I would prefer the second option as we see different output with clang-format when bugs are fixed

can be done in parallel of bug 1588185

@sylvestre, Is it required to modify the is_version_eligible function so that the version compares to a hard-coded version?

correct
are you working on it?

@Sylvestre I am new to open source so can you please guide me through this ? This seems a little bit overwhelming to open for the first time. Please guide me. Thanks

You will find the doc here:

Yes, I just wanted to get confirmed about the approach. Will be submitting the patch in a day or two.

@Syvestre i am getting error while building the setup ( ./mach build)
Error running mach:

['build']

The error occurred in the implementation of the invoked mach command.

This should never occur and is likely a bug in the implementation of that
command.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

TypeError: argument of type 'NoneType' is not iterable

File "/home/manthan/mozilla-central/python/mozbuild/mozbuild/build_commands.py", line 82, in build
doing_pgo = 'MOZ_PGO=1' in mozconfig['configure_args']

I am sorry but bugzilla isn't the place for support. if you think this is a bug in Firefox build system, please open a new bug
but it seems that you are doing you should not be doing (PGO). Please use an empty .mozconfig to start

where can i get help for this then ?

please follow the doc https://firefox-source-docs.mozilla.org/tools/docs/contribute/how_to_contribute_firefox.html

https://bugzilla.mozilla.org/show_bug.cgi?id=1601872 => maybe this is your bug

I have followed that document after which I am getting this error. And yes that is my bug

I have a basic question. How do you check if the code you have written is working correctly?

hey an outreachy applicant here can i try out this?
