Otherwise I can't make sense of it. The opposite. For subversion, revisions mark the whole repository, so a revision could have results for both trunk and a branch. That is not the case in mercurial. Regarding my explanation, I understand it is a bit difficult to visualize this UI issues without images. >> You would need to blindly search >> for your results.

Same as above. So the differences between version control systems really suggest that you cannot add a branch dimension to a revision. More like a result is not only associated to a project, revision, and executable, but also to a branch... 2011/1/21 Paolo Giarrusso : > Hi Miquel! > >> I would gladly hear other ideas. > Here are my two cents! > > On Fri, Jan 21, 2011 at 08:49, Miquel Torres wrote: >> So one idea would be: >> - Every revision has a branch associated to it (a problem though is >> that subversion has the same revision number for all branches, while >> mercurial and git not) > This suggests (to me) that a revision would be associated to a > specific branch, but then I don't get expressions like "all the > branches for a revision".

Otherwise I can't make sense of it. I guess you can use, on other branches, the "closest" revision available, after defining a linear order on revisions across branches. You have that order in SVN; since you don't have that in Git, why don't you just use the _date_ of a revision as the ordering key? [For the data structures to implement this, I've seen even seen interfaces to tree-based dictionaries allowing navigating to the key-predecessor and key-successor, which might be especially handy here (such as NavigableMap in Java, dunno about Python).] Of course, that's suitable just as default, so you need to be able to navigate between revisions independently for each branch. Please note that with complex merge histories, using the date does not necessarily make sense - so that at least Git tools provide many linearization algorithms. The problem is that a commit might be made on a certain date in some repository, but be merged on mainline much later, especially when many developers are not committers themselves; one solution is to consider only revisions which were committed directly on the branch or merged shortly after. I also would believe this use case does not appear for PyPy.

Re: [pypy-dev] New version of Codespeed (0.7) for speed.pypy.org
@Anto Yes, branches are a pending item that has been requested a couple of times now. The current solution is actually not to abuse an environment like you say, but to create a new project for a branch. That way it gets cleanly separated, and in a way branches are like different projects. But it is of course not optimal. Technically it is very easy to come up with several solutions (add a branch dimension, for example), but interface-wise it is not easy to find something that doesn't clutter things. So one idea would be: - Every revision has a branch associated to it (a problem though is that subversion has the same revision number for all branches, while mercurial and git not) - Branch would be a selectable parameter on the left menu box, just like executables or environments - You would be able to compare a branch using the comparison view, but another possibility is that the timeline view doesn't have branch as a radio button, but as a checkbox. That means that a plot is associated only to an executable and environment, and that you can choose to display either all branches in the same plot (trunk or master + any branch) or only the ones you select. - There are problems with this approach. In the Changes view, when you select a revision that doesn't have results for the currently selected branch, nothing would be displayed. You would need to blindly search for your results. An option is to always display all branches for a revision, but sometimes a revision will contain results for a branch, sometimes for others. Another idea would be to associate executables to a branch. This avoids the problem in the Changes view. But it is not really much different from the current solution of creating a different project for each branch. I would gladly hear other ideas.

From my side, there is only one feature that I miss a lot, which is the possibility to benchmark a branch. IIRC, at the moment if you just run benchmarks on a branch, they are appended to the list of results, which can be a bit confusing especially if you look at them weeks later.

[pypy-dev] New version of Codespeed (0.7) for speed.pypy.org
Hi all, I want to announce the release of Codespeed 0.7, the version which is now powering speed.pypy.org The announcement has been made on http://groups.google.com/group/codespeed/browse_thread/thread/3dd2d9491b26d044, but I will paste it here: -- I will briefly describe the most significant improvements. Result Reports -- While the previous Codespeed version allowed a project to analyse and visualize performance changes and compare different versions or even "competitors", it didn't address well a use-case: a core developer that is interested in the daily performance variations. You had to go to the Changes view, click on the desired revision, maybe another executable, and again for every revision you wanted to check. That use case is now addressed by Reports. They are a summary of the most significant changes on every run. It's a ultra-condensed Changes table. It is shown on the main page, and you can even subscribe to a RSS feed. That way you only visit the page when you are interested in some particular revision or change. After a few weeks of use, you may find out that a different "algorithm" is better (for example dropping trends or trends triggering the red state...), or that the thresholds need to be tweaked. And there are surely other interesting run statistics that could be gathered and shown. I eagerly await the feedback and ensuing discussion ;-) Support for small screen sizes -- Using CSS media queries, the site layout adapts to smaller screens. It is optimized for 3 sizes: - Desktop: normal layout for big screens - Netbook, tablets (~1000px): Similar layout but smaller margins, smaller plots. Coincidentally, it is about the same width of Maciej's laptop screen ;-) - Smartphones: iPhones and Androids in landscape mode should be now able to visit the site without problems. Though it can be tested just by resizing the browser window, it would be great to get some feedback of anyone actually using the above mentioned devices! Performance improvements Exarkun made the timeline view faster by pre-fetching all related data. The timeline grid took 1.46 seconds to load, and a single plot 0.45 seconds. They now need 1.26 and 0.26 seconds respectively. A big improvement! There is yet another improvement waiting in the wings, but we still need to figure out some regression it introduces. The Changes view is also much faster (from 480ms to 210ms), because it now uses the cached table stored in the corresponding report (only when viewing with the default trend=10 ). A last detail --- Another change you may notice is that the default checked executables in the Comparison view are now configurable (I didn't forget Maciej! :). So they are not all selected per default any more, so the plot shouldn't look any longer like the Flying Spaghetti Monster ;-) I'll leave it there. I hope you enjoy the changes!
