...using gource. Its quite interesting and funny to watch:

http://vimeo.com/36868024

Its only a few months from last summer until yesterday but you can watch busy developers flying around from file to file, watch the customdrawn interface grow and see which developers are mostly "attracted" by which parts of the project.

Nice.
I didn't know I was flying so much. :)

That`s so fun!

Look who does the things around here are a bunch of heroes. We have to increase this number. Making easy and secure is the way.

Everton, start providing patches. It is easy and secure! :)

Bernd, how long you think the animation is kept in the Vimeo site? It would be nice to have a similar animation from a longer period of time, saved in place where it will stay for reasonably long, and provide a link in Wiki pages.

There are amazing pieces of SW out there, like this "gource", which most people don't know about. I didn't know about it before this video.

Juha

Always that I can I will :) And you fly a lot brother! That`s so nice. Sure you have a very large view of it. Wish i had too.

Well, I had the idea that would be good to integrate in the IDE the process of bug report and patching. Today is too diffuse this work and many doesn't even know what it is. Make integrate in the IDE would make more concentrated and visible.

2012/2/17, Everton Vieira :

I don't really have so big view. The existing code must be studied always when creating new code. A good IDE with its code browsing and other features is important then, it works as an extension of the brains.

Do you have problems now creating bug reports and patches? What kind of problems?
I don't know how, and why, should patching be integrated in IDE. A patch is easy to make with "svn diff" for example. The difficult part is actually creating high quality code for a big project of over 1 000 000 LOC. There is no simple trick to make that easy.

Integrating bug reporting into IDE would have benefits if the IDE can trap an exception and include details of it in the report, together with info about the environment, and send it (semi-)automatically somewhere.
Until that is implemented, the current issue tracker works very well IMO.

I'm currently uploading an animation of the entire svn history I made tonight. I had to write a little python script to add some missing entries in the svn log when entire folders are renamed or deleted because gource can not yet deal with that correctly (it is normally best used with git). This time I made it in 960*720 pixel (HD quality) and with a nice Lazarus logo in the corner. It will be 7:43 minutes length. It is currently uploading (I have only little bandwidth) and should be available in a few hours.

It will stay at vimeo indefinitely. If you have an account at vimeo you can also download the original unaltered file (it is 120MB, h264 encoded). Maybe somebody can download the original file, add a sound track with some suitable nice and unobtrusive free music and re-upload it again.

I know, but let's make visible in the IDE.

I know too, that's why many like me are afraid of it.

I know too, the idea is only a front end, or by start, a link in the IDE, would do.

Juha

Understand, the idea is much more about to make visible than anything else. At least by now.

2012/2/18 Everton Vieira

And in that, could be thinking something about this movie too, it has to be more visible than is today.

Thinking of it more, the patch creation could be integrated in the lazsvnpkg. Now it has "Show diff for local changes" for a single file. It could easily make a full patch of the diffs.
This is a good exercise feature for you to make. For changing the relatively small package you don't need to study the whole Lazarus internals.
First you must use the cmd line "svn diff" for your patches, later you can use a self-made GUI for it. :)
I promise to look at your patches personally if you make some.

Understand, the idea is much more about to make visible than anything else. At least by now.

The whole project needs more visibility, yes. The command used for creating patches is not very essential for it. Every developer who is able to create code for a big project is also able to run "svn diff" or a similar command.

It is already integrated (I implemented this last year): Click on "commit" (because you want to commit your changes, via patch or otherwise) then the commit dialog comes up where you select the files you want to commit and then instead of the "commit" button you click on the "create patch file" button. This will create a patch file, you can preview it, edit it (remove individual hunks you don't want to include) and then save it to disk. The created patch file will include all selected changes in one file, is suitable to be attached to bug reports and to be used with the patch utility. I use this to make all my patches.

Bernd

PS: my earlier mentioned upload of the new animation was interrupted and then I also spotted an error, to fix it I need to encoe it another time, It will take a few more hours.

Just a note from my experience with patches:

My installation contains some patches, which probably never will go into the official repository. When I work on a new problem, and finally found a solution, a simple diff is not ready for submission. Instead the "new" modifications had to be extracted (how?), then tested in a clean environment, at least for completeness, before the final diff can be submitted.

This is what I (and other contributors) need support for, so that less patches are rejected only for formal reasons ("too much noise"...).

2012/2/18, Bernd :

Right! I didn't know of that. I use git + git-svn link myself. Ok, Everton, the tool is there. You can start making patches for other parts of Lazarus!

Bernd, do you maintain the package?
The patch feature works well but its GUI is little broken.
1. the ListView always shows a HourGlass cursor.
2. What are the 2 text controls up there, a Combobox and a Memo? Both are empty and have no hints or titles about their meaning. If I type something the the Combobox, I get a "List Index out of Bounds" error.
3. I got memory leaks sometimes (not always) from the "Show Log" feature. It is a good idea to use -gh always when developing.

IMO the "Patch" feature should have its own entry in the menu. "Commit" term is associated with SVN commits. I didn't understand to look for it there.

PS: my earlier mentioned upload of the new animation was interrupted and then I also spotted an error, to fix it I need to encoe it another time, It will take a few more hours.

No problem.
I am curious, how long does gource take to generate such animation? It uses some advanced auto-layout algorithm for the node placement, bloom effects and such details.
I could imagine it needs some processing power.
On the other hand, today's computers have a lot of processing power.

Juha

Now the memory leak came from svnstatusform :

2012/2/18 Juha Manninen :

I don't maintain it, I only made a few patches for it because it seems nobody else did anything in it for a very long time and I missed some features, so I quickly implemented them myself, but you are right, it still needs much more work. Are you using the stable 0.9.30 version or svn trunk? I recently fixed some memory leaks (the original version was only hidding some forms instead of closing them, kept pointers around to some of these hidden forms to show them again, sometimes provoking crashes, parts of it were/are pretty confusing. I tried to fix some of the issues and it became a lot better but I did not have enough time to find them all)

I cannot currently look at the problem you mentioned about the combo box because my PC is currently busy doing the animation (I cannot minimize the OpenGL window now or move any window in front of it because that would cause corruption and many hours time wasted) but I promise I look at it soon.

IMO the "Patch" feature should have its own entry in the menu. "Commit" term is associated with SVN commits. I didn't understand to look for it there.

I put the patch button onto the commit form because it shares the same work flow until the very last moment when you actually decide whether to commit to the server or to a patch file. Maybe it should be mentioned in the menu item: "Commit / create patch" instead of only "Commit"

Almost all processing power is used by ffmpeg for encoding the movie, this takes many hours on my rather old hardware. Gource itself is pretty fast and can generate it in real time with high frame rates.

2012/2/18 Juha Manninen :

The text control is for entering the commit message and the combobox is for quickly selecting one of the previously entered commit messages.

Please file a separate bug for every individual problem you find (you have found at least 3 different problems already) so they won't be forgotten. I will try to fix them all one after the other and hope somebody will apply my fixes before it is too late for Version 1.0

Yeah, I figured it out. In fact I become obsessed with the memory leaks and crashes and started to fix them myself. I think I got them all fixed now.
The code become much cleaner by using classes instead of records, and generics containers. Lots of ugly type-casts could be removed. See r35463 and r35469.

You could look at the remaining usability issues. At least the commit msg history list collects duplicate strings.
The HourGlass cursor problem seems to be a QT problem. With GTK2 it works better.

Didn't you say you're not so sure anymore about using generics in Lazarus? ;P

Well yes I did. :-)
In this case however it made a big difference for the code clarity. Please may use them also in future but only when the benefits outweight the memory and performance penalties that were discussed earlier.

I still believe someone (you maybe) will optimize generics in FPC in future and the issue mostly goes away.

Juha

I already looked at your changes before writing the mail. I just wanted to tease you a little bit :)

In the forms in LazSvn the individual controls' cursor is set to HourGlass and then to normal.
With QT bindings it remains HourGlass forever, at least for TListView and TCombobox. With other bindings it returns back to normal.

I personally like to use Screen.Cursor. It works well also with QT.

Ok, I made a new one, covering the entire SVN history:

Nice. Wonder whether it could be put on a server somewhere, with a new frame generated every time the revision changes and notification of the update sent out via RSS or similar with optional beep at the client?
