Feature/statistic

[rachmadaniHaryono]

based on discussion on #251

statistic page

• link added to navbar and index page
• result data saved on global variable (see below for description)
• add chart.js file and arrow package for humanizing statistic datetime
• refresh button to recalculate the data

TODO (maybe)

• tag statistic
• table for netloc and tag, which are hidden by default and expanded on button
• confirmation or enable/disable statistic page

from related discussion

it can more expanded, e.g. 
- most common word on description, 
- domain to tag relationship
- nlt for description
- (new) color generation
- (new) configurable number of common item
FUN idea: Badge:
- 0, 10, 100, 1k bookmark/tag
- sfw/nsfw/category bookmark achieved (have x website bookmark with max or min number)
- unique domain award (when unique domain is the most dominant)
- website bookmark (only bookmark certain website or it is 80% of the bookmark)

motivation

i decide to create pr for it even if it may not be merged.

the original motivation is just to search dominant netloc, but it is expanded and turned into some prototype about what can be done by a plugin on bukuserver

---

saved data

the original branch start without saving data to anything. it mean on each request the data will be calculated. the disadvantage of this is the time required when user have million of bookmark.

jarun:I think if we add this feature, users may want the data to be persistent. Hence, at some point we will have to work on making it persistent and add that option to enable it.

based on that recommendation, i try these method

• flask.g: i could be wrong when using this method to get bukudb (may have to create another pr to subtitute the entire use of this). related I think if we add this feature, users may want the data to be persistent. Hence, at some point we will have to work on making it persistent and add that option to enable it.
• class view: i thought the attribute on class view will be kept between request, but it is not.
• flask session: it is possible, but there is warning when there is too much data and browser may ignore it

/home/<user>/envs/Buku/lib/python3.6/site-packages/werkzeug/wrappers.py:1116:
UserWarning: The "b'session'" cookie is too large:
the value was 31762 bytes but the header required 26 extra bytes.
The final size was 31788 bytes but the limit is 4093 bytes.
Browsers may silently ignore cookies larger than this.

• global variable: the methode used currently, currently work. but related https://stackoverflow.com/questions/19158339/why-are-global-variables-evil

maybe last commit for this feature

now tag statistic is also on the page.

there is view all button which will open modal page showing table of the rank

e: also enable and disable statistic page ignored for now and (maybe) will be added on future commit

known issue

• it seems the time indicator may not work, so it will only show created x ago indefinitely.
• buku don't can't search bookmark, which don't have any netloc (something like javascript:....). so no link for (No Netloc) entry
• colors and number of default item is constant
• loading for the first time, which may take some time
• cache (may) not work

Thank you!

I misunderstood the statistics proposal earlier. It's aswesome @rachmadaniHaryono!

[jarun]

It would be great if one can click on the circle and open the corresponding bookmarks.

There should be possible by setting something here http://www.chartjs.org/docs/latest/general/interactions/events.html
