Re: [Sugar-devel] Errors while running sugar emulator
I feel you should try running sugar in Ubuntu's latest version i.e. 10.10 Maverick to get the latest setup running on your system also as a beginner (which I am only assuming , correct me otherwise.) you can also try running sugar on fedora which as per my experience has a better support for sugar and related components ,you can install fedora even on virtualization , presently I have sugar running perfectly on both ubuntu 10.10 and fedora 13 (both natively installed) on my system . I hope you can get it running .

Yes , I tried this solution on my end once as per Alsroot's suggesstion of implementing alpha pulsing instead of the present scenario but that did not solve the problem much as you may have noted due to the main problem lying in the rendering time of the startup frame of the animation.

Re: [Sugar-devel] Report on Sl# 2080 , Pulsing icon delayed by 5 seconds or so.
Sure , we can work to get a combined patch but your patch still disables the animation in most of the icons and we can check the real deal only after we can see the animation because thats the real part where all the system resources go and lead to that delay. We should first try to get that part working and then run fresh tests to check the improvements. On the other hand my patch my patch also gives a near 50% reduction in delay with the animation playing but the community still hasn't reached on a consensus regarding the issue so I guess we need to reach on a common point of approval , then only we can get any working patch accepted and move on to other issues.

Since , now we all seem to reach on a common proposal of agreement for the above issue . And since Gary has confirmed a noticeable improvement in the reduction of the delay time due to the changes applied by the v5 patch and some more tweaks discussed in the thread , so I think we can move to make a revised patch for this issue which can improve the situation for now and if we are still required to change the animation as the final solution we can later reopen the ticket as an enhancement request.

I have attached the pulsingicon.py file in which I placed the benchmark script to test the time taken by update function everytime it is called. I used the time.time() function to measure the time taken to process the update step. And If you may compare the odd steps of both logs i.e the numbers in the lines having seconds taken to update frame appearing at the odd steps (3rd ,5th ,7th.entries) and similarily compare the even steps you may find the average time taken on XO-1.5 to run the update function was nearly 50% faster.

Re: [Sugar-devel] [Dextrose] [PATCH v5 sugar] Pulsing icon delayed by 5 seconds or so SL#2080
The present issue has two possible scenarios of solving it 1) Optimise the present pulsing icon animation to reduce the delay : Thats what I have worked towards till now in my patches. 2)Replace the present pulsing icon animation with a better and faster animation: Thats what I think everyone agrees to be the best solution of the issue right now. If we're still taking about the v5 patch that was posted to the list, I don't understand how this change is supposed to fix the bug: +if self._count 2: + self.update() +self._count = self._count + 1 The animation of the pulsing icon is basically constituted by filling the raw svg icon with colours based on a sinusoidal function and it is this sinusoidal filling of the colour that brings about the pulsing effect , so if we dont fill the icon with colour then the icon wont pulse and would render and appear as a raw svg icon only which undoubtedly will take lower system resources to get rendered than the animation. Skipping the first frame of the animation unconditionally is wrong and isn't the same thing of skipping frames dynamically, based on the time elapsed to render the previous frame. I feel like we're trying a number of random tweaks without addressing the root cause of the problem. The first frame of the animation is not being skipped but its just not being filled with colour so as to make the pulsing icon animation start earlier and I hope we both agree on the fact that the delay is caused due to the time taken for the rendering of the zoom in and zoom out animation for the first frame. So if the load of processing the first frame would have been reduced somehow then the animation would start earlier and this approach was confirmed by positive log results upon benchmarking the whole scenario before and after the fix. Perhaps Anurag could work on a fix in team with other Seeta developers? -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Two screenshots were taken from camera as the screen shots of those two screens coudnt be saved as just after taking those two screenshots the journal gets restored and we lose our previous data of the journal which includes those two screenshots. Also It was not possible to take screenshots of the in-progress operation as the backup and restore operation completes in very few sceonds so I coudnt capture such a near instantaneous operation.

[Sugar-devel] [PATCH v5 sugar] Pulsing icon delayed by 5 seconds or so SL#2080
When we click on the icon of an activity we see a pulsing icon of that activity before the activity starts and usually there is a time delay between the clicking of the icon and appearance of the pulsing icon , where tha amount of delay differs by the complexity of the icon i.e. more complex the icon is larger is the delay. So In order to minimise the delay we replaced the animation with its raw svg image for the first frame of rendering only there by reducing the rendering timeof the first frame and hence reducing the delay and from the second frame onwards the svg image will be converted into the pulsing icon animation. To stop the pulsing icon from animating for the first frame we stopped the call to the update function for first two times only, as every frame has two update calls associated with it, once the update that preceeds the frame and the other that follows it. --- src/jarabe/view/pulsingicon.py |7 --- 1 files changed, 4 insertions(+), 3 deletions(-) v1-v2 corrected layout according to pep-8 format v2-v3 removed increment operation of variable i in the for loop v3-v4 added the concept of frame skipping v4-v5 changed the first frame of the animation to static svg icon diff --git a/src/jarabe/view/pulsingicon.py b/src/jarabe/view/pulsingicon.py index 43ec358..70040a6 100644 --- a/src/jarabe/view/pulsingicon.py +++ b/src/jarabe/view/pulsingicon.py @@ -30,7 +30,7 @@ class Pulser(object): self._icon = icon self._level = 0 self._phase = 0 - +self._count = 1 def start(self, restart=False): if restart: self._phase = 0 @@ -79,8 +79,9 @@ class Pulser(object): def __pulse_cb(self): self._phase += _STEP self._level = (math.sin(self._phase) + 1) / 2 -self.update() - +if self._count 2: + self.update() +self._count = self._count + 1 return True class PulsingIcon(Icon): -- 1.7.2.3 ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Re: [Sugar-devel] [PATCH v5 sugar] Pulsing icon delayed by 5 seconds or so SL#2080
Daniel, Thank you for reviewing the patch. Appreciate it. Wish to inform you that I did try the profiler, and displayed the time slice intervals between rendering of consecutive frames. I did find significant change in the rendering time of first frame. Raw svg icon with colour is timely filled using a sine function, which control its timing, and is updated on every frame of animation. Since, we have a 400 Mhz capacity processor in an XO-1, this has considerable processing lead times associated for completion of the rendering job. My earlier idea of frame dropping is a technique, which can smoothen an already started animation, but does not speed up the start-up.

[Sugar-devel] Bug update on ticket no 2080 (Pulsing icon delayed by 5 seconds)
Team, Wish to share on the observations that I gathered on the basis of my discussion with Bernie last evening. It seems that the delay that occurs before the start of the pulsing icon is due to the zoom animation failing to render . We arrived at the idea of using a technique commonly applied in video games i.e. Frame Dropping, where we drop frames in order to maintain the frame rate. Using this idea, I have prepared a patch for SL 2080, and have tried it on my XO-1.5, where it seems to work better. I have tried to skip the animation to the last frame if the fps drops below the defaults fps of 20 , for a smooth animation to occur. Wish if the patch could be reviewed on an XO-1. If I am making mistakes or missing on any key aspect, please share feedback bluntly. Appreciate your support. Thank you.

So here we tried to reduce that delay if not completely obliterate it , by making the duration of the first 5 pulses larger and during these 5 times the icon will only be zoomed in and not zoomed out so as to reduce the frame calculation load on the processor, Hence reducing the delay. --- src/sugar/graphics/animator.py |2 +- 1 files changed, 1 insertions(+), 1 deletions(-) v1-v2 corrected layout according to pep-8 format v2-v3 removed increment operation of variable i in the for loop v3-v4 added the concept of frame skipping diff --git a/src/sugar/graphics/animator.py b/src/sugar/graphics/animator.py index 8fb298b..e3a3503 100644 --- a/src/sugar/graphics/animator.py +++ b/src/sugar/graphics/animator.py @@ -136,7 +136,7 @@ class Animation(object): start = self.start change = self.end - self.start -if t == duration: +if fps 20: # last frame frame = self.end else: -- 1.7.2.3 ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
[Sugar-devel] Bug update on ticket no 2080 (Pulsing icon delayed by 5 seconds)
Daniel, Bernie and James, Appreciate your pointers. Indeed very helpful. Thank you. I tried to reduce the processing load just before the rendering of the first frame in this workflow, and looked for the processor intensive parts (intensive calculations or long recursive function calls) where any possible reduction in the processing may speed up the loading of the pulsing icon. I studied the files as pointed by Bernie (thank you for the explanation) and found the animation aspect to be constituted of only two frames - EASE_IN and EASE_OUT, which take place in an ordered repetitive manner. I was unable to arrive at a solution that was specific to the first frame with the documentation and explanations available. Wish if you could share pointers and strategy on how processor load could be lowered with emphasis on first frame. I suspect that it should lie in jarabe.view.launcher where the animation starts, but have been unable to arrive at an approach for it. Looking forward to your feedback. In reference to the questions on the patch submitted, I tried to reduce the delay by reducing the frame computation of the first five frames. Apologies that I did not consider the processing load that is encountered before the startup of the first frame of the animation of the pulsing icon. Appreciate your support and feedback.

So here we tried to reduce that delay if not completely obliterate it , by making the duration of the first 5 pulses larger and during these 5 times the icon will only be zoomed in and not zoomed out so as to reduce the frame calculation load on the processor, Hence reducing the delay. --- src/sugar/graphics/animator.py |3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) v1-v2 corrected layout according to pep-8 format v2-v3 removed increment operation of variable i in the for loop diff --git a/src/sugar/graphics/animator.py b/src/sugar/graphics/animator.py index 8fb298b..14e45e1 100644 --- a/src/sugar/graphics/animator.py +++ b/src/sugar/graphics/animator.py @@ -140,6 +140,9 @@ class Animation(object): # last frame frame = self.end else: +for i in range(5): +easing = EASE_IN_EXPO +duration = duration * 100 if easing == EASE_OUT_EXPO: frame = change * (-pow(2, -10 * t / duration) + 1) + start elif easing == EASE_IN_EXPO: -- 1.7.2.3 ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

[Sugar-devel] Pointers required for SL#1742 (after adding a friend the palette doesn't change) ,
What I figured out for this bug is that the bug could be solved only if the shell service has a D-Bus API for buddies. Untill then even the present scenario of one time update during system restart has also been applied through a hack place in sync_friends () in the jarabe.model.friends.pymodule this bug will get wrapped itself when the said api for shell service will get designed then even this sync_friends function would be removed. But I would need some pointers on how to create this dbus api for the present scenario and how will that work through the process to solve this defect. ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Re: [Sugar-devel] [PATCH v2 sugar] Shutdown and Logout menu items should activate the buzzy cursor (SL#2151)
Hello Tomeu , I actually worked upon your suggestion quoted in http://lists.sugarlabs.org/archive/sugar-devel/2010-September/026741.html to solve this bug. Actually I changed the cursor in homewindow this time and used glib.idle_add( ) to break out of the infinite gtk.main() loop to shutdown the system when the processor is idle and untill that time it will show a busy cursor which i think will be the proper method to shutdown while providing a visual confirmation of the process. Please let me know if adding this information in description would be sufficient. If required, I can add more information.Also I will resubmit a new patch which will be more descriptive than this one.
