I,

• Increased the size of the text space
• Increased the size of the 'google search' button
• Change the colour of the button
• Centralised the logo, text space and button, to maintain a better use of white spacing
• Added a console, so once you're on you don't need to click first before typing... just start typing

I am trying to load pages like google.com in Browse but it seems to get stuck. Below is the attached log for the activity session.

org.laptop.WebActivity-1.log

@quozl latest tag number is below it's predecessor, is this correct?

What is needed for merging the webkit2 branch?

Reproducer:

• download an activity bundle from activities.sugarlabs.org or wiki.laptop.org,

Observed result:

• activity bundle is both installed and left in journal

Expected result:

• activity bundle is installed and not left in journal.

Link - setup a development environment for Sugar desktop under "How to develop?" in README doesn't work.

@leonardcj, the current export of is.po and hy.po from translate.sugarlabs.org removes several translated strings. Is that right?

Reproducer: start Browse 201.2, show Frame, right-click on Browse icon, click on View Source.

Expected result: source of activity and page source.

Observed result: source of activity only, and an error message in logs;

Analysis: WebKit2 4.0 API documentation shows get_main_frame is no longer a method of WebView, so it looks like this code has not yet been ported to the API.

p.s. spelling error since fixed; occured should be occurred.

I'm testing webkit2 branch, and I found the following excpeption.

File "/usr/share/sugar/activities/Browse.activity/webactivity.py", line 492, in write_file

Attached you can find the log file.
org.laptop.WebActivity-1.txt

Logs contain

(sugar-activity:1376): Gtk-WARNING **: 15:41:06.295: Failed to set text from
markup due to error parsing markup: Error on line 2: Entity did not end with a
semicolon; most likely you used an ampersand character without intending to
start an entity - escape ampersand as &

No visible effect noted.

• use debugging or GTK environment variables to isolate to cause (a line number, obviously not in sugar-activity),
• fix the problem.

For anyone interested in working on it.

Reproducer: click on a PDF, open the edit toolbar, click on the search entry, type a word to search for.

Expected result: words searched for and highlighted.

Observed result: nothing seen, except for logs;

Steps to Reproduce:

1. Request a PDF resource from a URL
2. The pdf opens in a new tab

Logs:
AttributeError: DummyBrowser object has no attribute can-go-back

Reason:
DummyBrowser (GObject.GObject) doesn't have all the attributes of Browser (Webkit2.View)

Subject of the Issue
On visiting https://www.sugarlabs.org using Browse-activity and then using the Address bar if any keyword search is performed then the address redirects to website's search plugin instead of normal google search.

Test Environment

• Sucrose on ubuntu 18.04

Steps to reproduce

• Open Browse-activity
• visit https://www.sugarlabs.org
• Try to search any keyword using address bar of the browse activity

Expected Behaviour

• On searching any keyword from address bar it should redirect to google search

Actual Behaviour

• Keyword search redirects to website's search plugin.

We moved from the bug tracker to using github issues so I think the bugs hyperlink in the activity home page should be changed to our github issues.

@quozl thoughts?

Reproducer:

• click on activities,
• download an activity,
• view in journal,
• switch to detail view,
• examine mime type "Kind" and try to open the entry.

Expected result:

• application/vnd.olpc-sugar
• activity is installed and runs

Observed result:

• application/octet-stream
• No activity to start entry

Versions: Affects Browse-200. Browse-157 works fine.

Impact: critical, as it breaks activities.sugarlabs.org for current version of Browse in Ubuntu, Debian, Raspbian and Fedora.

Reported by @Rishabh42.

Adding readme file will help others to understand the project, what is there in the project and how to use it.

Steps to reproduce:

• Open a webpage
• Download a file (small enough to be download in ~5 sec)

Observed Result:

• download started alert is present even after download completed

Proposed Result:

• download started should be replaced by Download completed on completion
• as implemented in 19c0ad7

Kindly review this issue, since I am unaware if the present implementation was intentional

Browser tab titles are set from page content, and when a resource is being loaded they are set to "Loading..."

When a resource load switches to a download the title is left as "Loading..." but should instead switch back to the title it had before.

Just installed a clean sugar on a debian:testing, but the browser is not launching. In ~/.sugar/default/logs/org.laptop.WebActivity-X.log it says:

ln -s /XXX/Browse.activity/collabwrapper/collabwrapper.py /XXX/Browse.activity/collabwrapper.py

and modify the import in

from collabwrapper import CollabWrapper

It works like a charm. I'm not a python expert and have no idea what that means, but maybe you know?

https://github.com/sugarlabs/browse-activity/blob/master/activity/activity.info contains the following license.

license = GPLv2+;LGPLv2+;GPLv3+

which is not valid SPDX license expression. Hence it's reported as non-foss app in GNOME Software.

Refer https://gitlab.gnome.org/GNOME/gnome-software/-/issues/2540

In browser.py __decide_policy_cb when the MIME Type is application/pdf the in-progress or completed GET request is abandoned and a second GET request is made by the PDF viewer.

This uses more internet bandwidth and causes double-counting in server logs.

Using sugar-build (latest one! :P) I get

Maybe it works on fedora rawhide, or smh. But we should provide support to sugar-build on debian or similars.

There might be a leak somewhere. 2 ways this is visible:

1. Do normal browsing for 10 minutes. After about 10 minutes, switching between tabs will result in a grey screen for ~5 sec and the browser becoming laggy. The toolbar (the Sugar stuff) is still responsive, but all of the web views are terrible.
2. Open a video (eg. https://www.youtube.com/watch?v=SYRlTISvjww). Press play. Hear the song for a little bit. Close the tab. The song will continue playing for a very long time (~30sec on my last trial, but I swear I have seen longer before). Are we not destroying the tabs when we close them? What is happening?

Reproduce:

1. Open browser-activity, type www.youtube.com and play a video. (or)
2. Search something(on Google) that shows video suggestions and hover the cursor over it for a bit. (or)
3. Open a web page with heavy graphics (homepage of GitHub) and scroll down half way.

On Ubuntu 18.04 with Browse 7cfd9f2 and v202, scratch.mit.edu online editor v3.0 does play sound fine, but does not record sound. When an attempt is made, a dialog from the web app is shown, but it is insensitive. There is no WebKit2.UserMediaPermissionRequest sent. Console shows an internationalisation error in the web app;

projects.bundle.js:68:13595
Unhandled Promise Rejection:
Invariant Violation: 
[React Intl] An `id` must be provided to format a message

Reproducer:

• start Browse, open https://scratch.mit.edu/, click on Create, await loading,
• click on Sound (purple circle),
• click on Meow in play sound, and select Record ...

Attemping to bisect by wrapper, MiniBrowser from libwebkit2gtk-4.0-37 does not render the editor at all.

Works fine with Firefox, which pops up a permission request at this time. If the permission request is refused, the editor remains in the same state as shown by the screenshot above.

https://www.html5rocks.com/en/tutorials/getusermedia/intro references an audio record demonstration at http://webaudiodemos.appspot.com/AudioRecorder/index.html which likewise does not work.

So the cause is a failure to receive and handle the permission request.

On Ubuntu 20.10 and 22.04 the search entry box looks odd; a blue outline is incomplete at corners.

https://github.com/sugarlabs/browse-activity/branches has a lot of stale branches, some 9 years old XD

Steps to reproduce:

1. Open Browser
2. Request a PDF resource from a url
3. The PDF opens in a new tab
4. Mark it as favorite (The rest of the toolbar(except StopButton) should be disabled)

Expected result:
The link will be marked as favorite and a snap of the same will be added to the bookmark toolbar at the bottom

Observed result:
The link is marked as favorite, but the snap doesn't get reflected in the toolbar, only a blank icon is shown.
The snap is displayed on stopping and restarting the activity

Possible reproducer: start Browse, enter a URL of a PDF document, switch between default tab and the PDF tab repeatedly.

Conventional desktop browsers provide this feature. Middle click on a link should open the link in a new tab, without changing the current view.

Tested on the login form of gmail and my school's LMS

When you type, there is a huge lag between you pressing the key and it being entered. Everything looks like it has the slow type effect going - all the key presses are spaced out 500ms.

The rest of the ui (eg. mousing over a dropdown menu in the LMS site) is very snappy. But not the typing. Is this our fault or is it a webkit bug?

On Raspberry Pi OS, starting Browse shows in log

Could not determine the accessibility bus address

No impact.

When viewing a web page (using the WebKit.WebView widget) the scroll bar does not render in the Sugar theme. See also screenshots in godiard/help-activity#100. A tab using the EvinceView.View widget does not show the problem.

Due to a bug in the preview generation, image download is currently broken in master (the python3) version. Issue is using io.StringIO, where io.BytesIO should be used. A preview is being generated, but size of image in preview is small. That's due to another issue though, haven't debugged that yet.

below patch fixes the download issue for me. Tested with python3 (2 not revelant, as master is for python3 only, right?) and download of images works again.

Bas Hulsken

When the Develop activity is present, and a bundle is downloaded, Browse offers to open the bundle in Develop. It should instead offer to run the downloaded activity.

• Use SoupCookieJarDB in Soup instead of SoupCookieJarSqlite in SoupGNOME.
• Retain backward compatibility with existing user database.

Browser activity fails to start on Raspberry Pi

• v207 gets installed instead of v208 after installing sucrose apt package. (I don't know whom to ping for apt)

  apt show sugar-browse-activity returns
  Package: sugar-browse-activity
  Version: 207-2

  v207 has rendering issues but we can ignore this and focus on v208:
  (will upload a screenshot soon)

• after updating, v208 (latest as of now) returns:

  Traceback (most recent call last): File "/usr/bin/sugar-activity3", line 5, in <module> activityinstance.main() File "/usr/lib/python3/dist-packages/sugar3/activity/activityinstance.py", line 179, in main module = import(module_name) ^^^^^^^^^^^^^^^^^^^^^^^ File "/home/pi/Activities/browse-activity/webactivity.py", line 31, in <module> gi.require_version('Soup', '3.0') File "/usr/lib/python3/dist-packages/gi/init.py", line 129, in require_version raise ValueError('Namespace %s not available for version %s' % ValueError: Namespace Soup not available for version 3.0

To summarize, there are 2 issues:

• Installing sucrose from apt, installs the old version (v207) which is "buggy"
• v208 returns an error stating Soup 3.0 is missing

May be caused by environment variables inherited from Terminal, which would mean the fix may also be done to Terminal.

Workaround: start from Sugar home view.

Fullscreen mode should show only the active tab of the browser.

It seems that the stop button is broken - related code contains what seems to be a typo (missing "E"):

if web_error.code == WebKit2.NetworkError.CANCLLED:

NB! I have not tested if code works or not, only noticed by skimming through source commits.

When starting Browse activity 200, default homepage URL gets downloaded, not rendered.

NB! I am testing Debian soon-to-be-in-unstable Browse package with only-in-unstable Sugar packages, so there is a real risk that I have missed some dependencies or broken something in the process of repackaging.

python3 branch depends on telepathy-python which isn't available for Python 3, so can't be merged.

Evince has an Inverted Colours toggle in the File options with a shortcut of ctrl+i. Add the same shortcut to invert colours when viewing a PDF with Browse.

General license - e.g. in metadata for Github - is GPL-2+, but some parts (progresstoolbutton.py) is GPL-3+ - i.e. is incompatible with the overall license.

I believe you should adjust the metadata llicense to reflect not the most common license used (GPL-2+) but instead the effective license that all code is licensed to migrate to: GPL-3+.

Sometimes an error is thrown while trying to copy an image.

Reproduce:
right click -> copy image

Tested on:
Sugar 0.117-3, Debian Bullseye
Sugar 0.117, Sugar Live Build

Errors appear while trying on Google Images, but worked without issues on the same image later.
Not sure how to reproduce this accurately.

Observed result: Google Search is given the URL

On Browse Activity on Sugar (Tested Debian 12), the button "Try Music Blocks" on https://www.sugarlabs.org/music-blocks/ doesn't seem to work.

I tested on my own machine with FF, and it works fine.

(My son seems to want to go there to use MB, but it fails every time.)
