Design
Designed by Chris Howse
Implementation
Missing features from current design
- dashboard ->
- toolbar ->
- product - not implemented
- platforms - not implemented
- top tests - not implemented
- data grid ->
- row/column should not scroll
- toolbar ->
- custom chart ->
- toolbar ->
- running time - time delta/time delta % not implemented
- show changesets - needs design work
- may need hgpushlog work to link directly to changesets
- export CSV - server broken
- link - needs url shortener
- embed - not implemented
- set selection range based on URL
- add test data ->
- put popular branches/tests/platforms on top
- toolbar ->
- plot
y-axis should always be 0-based
Performance optimizations
- split up JSON files as discussed in status meeting
- look into constraining by date range
set Last-Modified headers on all JSON feedsespecially the manifest!already setting 15m Expires/Cache-control max-age
add caching proxy (varnish, etc)- improve charting performance
- "double-buffering" canvas for flot
- use node.js to generate static images for dashboard?
- flot group post
- stack overflow discussion
- custom chart is much faster if each series is written to a hidden canvas then shown when they are all complete
- look into reducing number of points
- flot plots way more than is actually useful when graphs are very dense, flot group discussion
- look into flot alternatives
Testing
- stand up vhost with old graphserver, pointing at nightly database, for QA comparison
- set up lint and tests on Hudson
- stand up auto-update for code (5 minutes) and DB (nightly)
- (QA) compare actual submitted data to JSON, and confirm in interface
- make sure proper changeset range is shown for checkins
- check with catlee on how the tree-management script does this
- follow-up irc convo w/ ted on catlee on changesets coalescing
