Alternatively, I could make it point to trunk (master) to avoid updating this often

Thank you for doing this, I kept forgetting about this.

I'd rather have it not pointing to master though.

(there are some changes due that will make this easier than it is now anyway, so it wouldn't be much of a bother to update as it is now)

[madhur4127]

Oops, I made it point to master, we can revert the topmost commit to undo.

so this will only ever install once, right? Is the intention to install "trunk" pahole? (like the other PR implies?)

[mattgodbolt]

And by that I mean:

• elsewhere trunk not only means trunk, but the current (at least built daily, trunk)
• so I think we should mean the same here :)

This is OK as is but we should consider moving this to our yaml stuff wihch can deal with this much better.

[madhur4127]

The intention is to point to master and build pahole everytime and install it in ${OPT}/pahole (this dir is unchanged). Instead of having to upgrade versions every now and then.

Digging more made me realize that this script is invoked by a cronjob (every 3h). So I think the best way is to download and build the pahole and then install the binaries in the end to overwrite existing ones.

[mattgodbolt]

This script is invoked daily at 3am, which is fin....we just need to remove the if check and it will install nightly.

In a separate PR we can make it build using our existing system. I'll make the change and merge in.

[madhur4127]

new changes will always download and build pahole from the master branch

[mattgodbolt]

Ah! You made the change already, perfect. Thanks!

[mattgodbolt]

I'll merge and fix the test errors
