We should have a README for the comm repository (aka Thunderbird) to help provide some guidance to those who pull down the source code.

The README should accomplish the following:

  • Explain the Mozilla Codebase
  • Teach how to build Thunderbird
  • Teach how to run your build
  • Point to how to contribute
  • Explain how to submit a patch

Some more comments:

As noted in the mailing list thread - MDN is going to remove our stuff. We need to update DTN regularly with the relevant information.

(In reply to Jorg K (GMT+2) from comment #14)

Some more comments:

  • Who's going to keep this up-to-date?
    You mean DTN? I've tried to get developer's involved to review the content and ensure it is up-to-date.

I will discuss this with Magnus today and see if we can get this task on a staff member's plate to check on these things regularly.

I used what Magnus recommended putting there. But this could be something different. What do you think is most useful?

  • Why are you only mentioning hg bookmarks. Some people use hg queues, so IMHO it should at least be mentioned.
    I've had some folks point out that hg queues is deprecated and probably not a good thing to encourage.

We do have a full section dedicated to Queues on DTN -> https://developer.thunderbird.net/contributing/fixing-a-bug/using-mercurial-queues

I'm open to feedback. So far I've had a hard time getting any attention to this README. Happy to get feedback.

I'll get back to this.

Flags: needinfo?(jorgk)

"Who's going to keep this up-to-date?" was referring to the readme itself. I guess it doesn't have too many details which will go out-of-date soon, but it's another location with build information which potentially will need updating.

I'd remove/replace the link.

I know that hg queues are supposedly deprecated, but everyone is using them. So would at least mention them.

Giving users too many options up front is often more cause of confusion rather than being helpful.

I will keep it up-to-date with a recurring calendar reminder to check on it and update it.

What would you replace it with? Happy to do it, just want to know what a good alternative would be.

I know that hg queues are supposedly deprecated, but everyone is using them. So would at least mention them.

The best I can do here is mention "You can also use hg queues to manage your patches to Thunderbird, you can learn more about them here."

Flags: needinfo?(jorgk)

What do you think Jorg?

Flags: needinfo?(jorgk)

I'd change the paragraph to:

Mercurial is pretty flexible in terms of allowing writing your own code and keeping it separate from the main code base. You can use using Mercurial Bookmarks or Mercurial Queues or for managing your work. We have guides called for bookmarks and queues on our developer website.

I've discussed the issue with John, and personally I don't think bookmarks are up to doing the job. So I'd not recommend anything. Mention bookmarks first if you want, since B comes before Q ;-)

As for the query. I'd but this:

Use the Advanced Search section to find bugs you want to take care of, and be sure that the bug doesn't currently have any user listed as Assignee and the Status is set to NEW. You can see a list of "easy" bugs for beginners via this query. However, we assume you came here to fix your "pet hate" bug, so you already have a bug to work with.

BTW, the query is: https://mzl.la/2HbDSyX

Attachment #9087157 - Flags: review?(jorgk) → review+

I've come to fix the link and land this, but it's still not right :/

Here's the bookmark example:

  1. Run hg pull to download the latest changes from the remote repository.
  2. Run hg update tip to update your current working directory to the most recent changeset that you just downloaded.
  3. Run the command hg bookmark some-bookmark-name to create a bookmark that points to the current changeset. Usually the name of the bookmark is related to the bug or feature you are working on.
  4. Run hg bookmarks to list all of your bookmarks and see which one is currently active. The one you just created should now be active.
  5. You can run hg log to see which bookmarks point to which changesets.
  6. Make changes to the code until you are ready to commit them.
  7. Run hg status and hg diff to check what files and changes you are about to commit. If you need to add a new file use hg add some-filename before committing.
  8. Commit your changes with hg commit -m "Bug ##### - fixing something amazing". The -m is short for --message and lets you provide a commit message for your changeset. "Bug ##### - fixing something amazing" is the format we recommend for the commit message, specifying the number of the Bug you're working on and a small description stating what you fixed. Use hg log to see examples of commit messages.
  9. Run hg log and note how the bookmark has moved to the changeset that you just committed. The active bookmark will automatically move to the most recent changeset as you commit your changes. That way you can make a series of commits and the bookmark will always point to the most recent one.
  10. You can use hg commit --amend to change your previous commit rather than making a new commit.

You're cheating since you're re-using numbers. Let me give you the much shorter hg queues steps:
0. Run hg pull to download the latest changes from the remote repository.

  1. Run hg update tip to update your current working directory to the most recent changeset that you just downloaded.
  2. Make changes to the code until you think you covered everything.
  3. Create a patch for upload with hg qnew -m "Bug ##### - fixing something amazing". The -m is short for --message and lets you provide a commit message for your changeset. "Bug ##### - fixing something amazing" is the format we recommend for the commit message, specifying the number of the Bug you're working on and a small description stating what you fixed.

The last command will place a patch into .hg/patches in your repository.

You can now scrap the #### Create a New Patch paragraph completely.

So four steps instead of ten seems much simpler, no? Both instructions are missing the information how to get rid of the local changes. You won't need them since the sheriff commits them to the repository and you will pull them from there.

Attachment #9087157 - Flags: review+

I have not gotten rid of my habit of using merqurial queue (this was the method of choice back when I started to create patches).
However, it is quite true that the use of HG MQ is highly discouraged now and there are bugs with |mach bootstrap| that interfere with the proper setting of .hgrc so that MQ works correctly.
So at least, we should mention for the benefit of newbies that "support for HG MQ in various mozilla tools is being deprecated, and you are better off to learn how to use bookmarks".

Attached patch new-readme-for-thunderbird.patch (obsolete) — Splinter Review

I've thought a lot about this and I am not going to change it to detail mercurial queues as there are a lot of warnings out there in documentation that we shouldn't be using it as it is deprecated. So I have noted that "While some find mercurial queues easier to work with, support for them is being deprecated in various Mozilla tools, so the example below uses bookmarks."

I have also fixed the numbering of the bookmarks instructions.

Let me know what you think, if there is nothing else I would like to see this merged.

> Let me know what you think, if there is nothing else I would like to see this merged.

I prefer the bookmark section to be removed. We have the link to the documentation, so let's refer people there. There's no need to have the same information in two locations. As per the maildev mailing list thread, the bookmark page needs work, so no point copying an incomplete page into the readme.

Also, please check the "space after full stop" style. The typewriter days are over, so we no longer use two spaces after a full stop. Search for ".  " (dot space space) in the document.

Sorry about anther iteration here.
Attachment #9091103 - Flags: review?(jorgk)

Hoping this is the final pass. I couldn't find any double spaces that you pointed out at the end of sentences. I did a search in three editors finders and then went line-by-line and checked. Can you point me at where you see one?

I completely removed the hg bookmarks example and just pointed them at documentation. Kept the rest in the READE about what to do after exporting the patch. Let me know what you think.
