comment:3 by walty <walty8@…>, 4 years ago

I suppose I should add a new parameter (e.g. report_id) for the TicketQuery module, is that correct?

btw, should I build the logic from scratch, or I better start from the code inside the WikiReportMacro?

thanks

comment:4 by Jun Omae, 4 years ago

I think we should add new macro for reports rather than extend TicketQuery macro. The several parameters of TicketQuery macro are not available for reports, e.g. format, group, verbose, col and reports can use variables, e.g. USER.

comment:5 by Ryan J Ollos, 4 years ago

I agree with adding a ReportMacro rather than extending TicketQuery.

comment:6 by walty <walty8@…>, 4 years ago

But if th:WikiReportMacro already exists, does that mean there is actually no further thing that need to be done?

comment:7 by Ryan J Ollos, 4 years ago

I think it makes sense to add the equivalent to Trac.

comment:8 by walty8@…, 4 years ago

hi,

Here is a quick patch regarding to the issue: de62ac71.diff.

(de62ac71 for a view-friendly page)

Please note that, I just shameless copied the code from the ​th:WikiReportMacro.

Since the WikiReport.html in the plugin has overlapped with report_view.html in trac core, I did a simple refactoring of report_view.html, and move the common part into a new template file (report_table.html). I am not sure if this is appropriate.

And two quick questions here:

  1. This time I handed in the patch as github diff link instead of patch file, I wonder if this is fine?
  1. How should I write unit tests for this one? Any direction please?

Thanks.

Thanks. I'll review again. Well, could you kindly create a branch like t12171 rather than trunk in your repository?

  1. How should I write unit tests for this one? Any direction please?

I think TicketQueryMacroTestCase and QUERY_TEST_CASES probably are of help to add unit tests.

comment:10 by Ryan J Ollos, 4 years ago

For staging work on GitHub as a contributor without commit access, I learned from tips in comment:11:ticket:11028. Someday it would be nice to extend TracDev/SubmittingPatches with tips for providing changes via a fork on GitHub, so we can help potential contributors get up to speed quickly with the modern tools.

comment:11 by walty8@…, 4 years ago

thanks ryan for the suggestion.

Here is the branch for this ticket:1.0-stable-t12171

And here is the comparison link for the final patch: compare

In the latest commit, the followings are done:

  1. Moved the macro from wiki/macros.py to ticket/query.py, since the code is more close to TicketQuery module.
  1. Added unit tests
  1. (As suggested by Jun Omae) Restored the req.args after the macro rendering, so as to remove the side effect to other modules.

comment:12 by Ryan J Ollos, 4 years ago

Initial feedback: Probably ticket/report.py is the most appropriate location.

Replying to Ryan J Ollos:

Initial feedback: Probably ticket/report.py is the most appropriate location.

Actually I thought about that, but in that case some of the unit test case logic (e.g. ticket_setup and ticket_tear_down) may not be reused easily. Is it OK if I import those functions from trac/tests/query.py into trac/tests/report.py?

comment:14 by Ryan J Ollos, 4 years ago

Added some comments to e49f1cf8.

Also:

  • You can squash your changes and then cherry-pick the single changeset over to a new branch based on the trunk, so that your changes are based on trunk (comment:9).
  • The main test logic needed to create macro tests in trac/tests/report.py is provided by trac.wiki.tests.formatter. I imagine you may also want to use the method _insert_tickets. Code like that can be copied, but just make sure you understand the code you are copying. Eventually I'd like to find a way to eliminate some of the duplication (#12211).

I think it's a good start to copy code from WikiReportMacro, but it uses a hack of calling ReportModule._render_view and we'll want to implement a more proper solution. I think it may involved extracting some code from ReportModule to a function or method. See also #12219, which I will try to finish up soon. Changing ReportModule may be the most challenging aspect of this ticket, if you can make all the other changes first then we can tackle that at the end. In the meantime you can continue calling ReportModule._render_view, which needs a req object. Since we don't want to change the args of the req object that is passed in formatter.req, you can probably use copy.deepcopy to create a new Request object. If you have problem with that you could try to create a mock request with Mock from trac.test.

I'll try to get back to you more quickly in the future so we can iterate towards a solution.

One quick question, if I squash the changes first, would it affect the code review comments on github?

Replying to walty8@…:

Yes, it will. That's why you should never rebase a branch that you've made public. Instead, you create a new branch based on your branch and rebase your new branch, leaving your old branch frozen in time forever. Usually we just append a .1, .2, … as we create new branches that need to be rebased. For example, see #11901 in which I'm currently working with .15, but have not yet published (log:rjollos.git:t11901-remove-deprecated-code-in-1.3.1.14 in comment:37:ticket:11901 is the latest published).

$ git checkout -b t12171 1.0-stable-t12171
$ git rebase -i

For your case, since we even want to go one step further and have your changes based on trunk rather than 1.0-stable, we can do the following;

Actually, I wouldn't be surprised if there's a better way to do that. With Git there's always several ways to accomplish the same task.

Future rebases will be much simpler.

Replying to Ryan J Ollos:

(snip)

Thank you very much for the detailed explanation! I finally managed to work out a new single commit on the new branch.

I would push the new commit to GitHub after all the previously raised comments are fixed.

(please just quote what you need, no more, thanks! For example, if you have to address several different points raised in one comment, it's good to keep an excerpt for replacing the reply in context; here the "comment:18 in reply to 17" is enough to get the context)

Yes, I think it's better to use the "rebase onto" way, instead of cherry-picking:

$ git checkout -b trunk-t12171 1.0-stable-t12171
$ git rebase 1.0-stable trunk-t12171 --onto trunk
# conflict resolution as before, except with `git rebase --continue/--abort` now

You could pass -i already at that step, and squash things in one go. Depending on the situation it might minimize the number of conflict resolution (say you have a conflict in first commit, subsequent commits keep modifying the lines you had to change in order to resolve the conflict → more conflicts).

You may name the branches as you want, but for ticket fixes, tXXX[.n] is a good choice, and if you have to add the base line (as soon as you have to disambiguate), I'd prefer to use the version as a suffix rather than a prefix (i.e. here, you could have started with just t12171, then t12171-trunk).

comment:20 by Christian Boos, 4 years ago

And finally, now that you know how to rebase on arbitrary branches, why not be future-proof and have a try at rebasing your changes on the cboos.git@jinja2 branch? ;-)

(until we make the branches from the TracTeam/Repositories available again without the need to authenticate first, you can fetch the branch from its github mirror)

comment:21 by Ryan J Ollos, 4 years ago

Thanks for the additional tips. I'll use them when revising TracDev/SubmittingPatches (comment:1:ticket:12358).

comment:22 by walty8@…, 4 years ago

hi,

Sorry for the late response. here is my latest patch: 8500a81.

Unfortunately I failed not accomplish a full refactoring of _render_view and self.execute_paginated_report, as it's just too hard for me. However, I added an optional argument args to the function _render_view, so as to avoid the copy of req.args.

Here are some uncertainties I would like to raise:

  1. I imported an internal class named _RequestArgs, which is odd
  1. I removed the public function of get_var_args in order to remove the dependency of req.args. I tried the grep and make sure no others used this function, but I am not sure if it’s used by other Trac plugins. If it’s necessary to keep this function, I would need to use some other work around which would add extra complexity to the small function.
  1. In the unit tests, I copied the method of ticket_setup and ticket_teardown from trac/ticket/tests/query.py to trac/ticket/tests/reports.py
  1. For some reasons, the squashed changed still appear in the github website, yet the commit mentioned above should be complete and latest.

I am sorry I did not fully understand the git rebase .. onto thing, I finally used the most basic way to accomplish it:

git checkout -b t12171.3.cboos
git rebase mirror.cboos
#a lot of git rebase --skip
git rebase -i HEAD~5
git push

The final commit is 4493f81, and it seems to work.

Please see if this is fine, thanks.

Well, no, you missed something here, you just rebased on trunk somehow, not onto the Jinja2 branch.

The idea is that you to a rebase like that:

             trunk t12171.3
               |   |
----------------++++
 \---------
          |
        jinja2
             trunk t12171.3
               |   |
----------------++++
 \---------****
          |   |
       jinja2 t12171.3.jinja2

The point of that branch is to go away from Genshi templates and use Jinja2 templates, so instead of a brand new Genshi template trac/ticket/templates/report_table.html, you need to refactor the trac/ticket/templates/jreport_view.html, extract the table rendering part into a separate Jinja2 template jreport_table.html, and then include it from trac/ticket/templates/jreport_view.html and also use it from the macro. The call to Chrome.render_template should remain the same.

hi ryan, please use bdc051 for the final patch, I found that the previous merge process missed one refactoring in the trac/ticket/templates/report_view.html.

comment:26 by Ryan J Ollos, 4 years ago

One of the committers will need to do some refactoring work in the report module to address the areas you didn't feel comfortable touching, so this work won't make it in until milestone:1.3.1. Given that, the work will need to be rebased on Christian's Jinja2 branch and the templates ported to Jinja. Next step is to follow his advice in comment:24 and see if you can get it rebased on his branch and working with a Jinja2 template.

in reply to:  24 ; comment:27 by walty8@…, 4 years ago

hi Christian,

Please find the latest patch using jinja version in 5c1ed9.

It's actually very easy to use the jinja2 templating system, but the git rebase or git cherrypick is an absolute pain! It took me 5-6 different attempts to do the merge.

The main problem I got is that I attempted to merge some commits that are already pushed. (This is because I have to use different machines to do development in different places, and I can't put all unpushed commits in one place and rebase them.) And that caused branch diverge and then all kinds of subsequent headaches.

Eventually I used the following approach to consolidate the changes.

E.g. I need to rebase last 4 commits of branch_a and consolidate them into a single commit in branch_b for each better patch submitting:

  1. do a rebase for the remote commits (already pushed commits)
    git rebase -i origin/branch_a~4 origin/branch_a 
    
  1. create a new branch using the detached HEAD (created from step 1)
    git branch branch_b HEAD
    
  1. push the new branch to github
    git checkout branch_b
    git push --set-upstream origin branch_b

Thanks! That one looks much easier to review, indeed.

It's actually very easy to use the jinja2 templating system, but the git rebase or git cherrypick is an absolute pain! It took me 5-6 different attempts to do the merge.

Also, the fact that you had to add getint and so on is simply because my branch is now lagging and needs to be rebased on latest trunk as well.

So roughly the plan is still 1.2 → 1.3.1 clean-ups from Ryan → (py3k changes from Jun)? → Jinja2 → (this ticket).

There are a few ways to deal with that, but I suggest for simplicity that you just always push your work in progress to your remote at the end of your work session. You can then pull it down before you start work on your other system. You can always create a new branch and rebase it before you make the work public. Basically, don't worry if your work-in-progress branches are sloppy, you can always clean them up before you post the changes for review.

Alternatively, I'd use git merge and then rebase the changes, or just rebase one branch onto the other.

And that caused branch diverge and then all kinds of subsequent headaches.

Eventually I used the following approach to consolidate the changes.

E.g. I need to rebase last 4 commits of branch_a and consolidate them into a single commit in branch_b for each better patch submitting:

  1. do a rebase for the remote commits (already pushed commits)
    git rebase -i origin/branch_a~4 origin/branch_a 
    

You shouldn't have a detached HEAD after a rebase. To squash 4 commits into 1 you'd just specify "fixup" for the last 3 commits, save and let the rebase run.

  1. create a new branch using the detached HEAD (created from step 1)
    git branch branch_b HEAD
    
  1. push the new branch to github
    git checkout branch_b
    git push --set-upstream origin branch_b
    

Here is an example of how I'd rebase the t12171.3 branch as you:

Could you give that a try so that we have your changes rebased on the latest trunk? You'll find there are a good number of conflicts. More rebases might be needed before the changes are committed, but this one would at least be good practice.

I've rebased Walty's latest changes and will do the additional refactoring in ReportModule (comment:26). I'm thinking we should name the macro TicketReport, since we already have TicketQuery macro.
