Today I am going to write about how to use hg push-to-try command in firefox. I was very much familiar with git and became familiar with basics of mercurial while applying for Outreachy. I can proudly say -Open source taught me Git and now teaching me advance topics of mercurial 🙂 and the fact is I am loving it.
Ok! so First of all, before doing push-to-try you need at least Tier-1 commit access. If you have one you can go to next step. Please read about how to get tier-1 commit level access here and definitely this one. Once you have Commit access, you can proceed for push-to -try.
Ok, Now I am assuming that you have tier- 1 commit access. So if you have a tree with your changes you should be able to push to try using mach or hg push-to-try.
hg push-to-try <option> “<specify try syntax>”
You probably want to specify try syntax, you can do that from TryChooser.
So how to Obtain syntax from TryChooser?
Go to the above link , it lets you choose with tickboxes and radio buttons what builds you need and what tests you need and it generates a string at the top in the greyed out textbox that you can copy/paste as a commit message for try, So, let’s start from left-hand side i.e Build type, Like in my case I only want optimized builds, not debug builds so I pick “opt only”, then under platforms, I am only changing linux, so I pick “linux” and “linux64”
and in my case, because I don’t need tests or performance benchmarks So, I am done. And syntax are something like this:
try: -b o -p linux,linux64 -u none -t none
mach try -b o -p linux,linux64 -u none -t none
So, According to the Computed syntax my push-to-try command in terminal should be like this:
hg push-to-try -m “try: -b o -t none -p linux,linux64 -u none -t none “
A treeherder help reviewer in many ways. Reviewer directly run build from your treeherder-ah, it saves the time(nothing better then this needed 😛 ). So just commit your changes, push it to the review board and push-to-try 🙂
