Adding Functionality to the Browser Based UI for Mercurial History Browsing, hgweb
Project Description
Mozilla is just starting to use an exciting new distributed version control tool: Mercurial.
One of the exciting things about Mercurial is that the history—the list of all the changes that have ever been checked in—is not linear. It frequently has branches and merges. This is actually a good, important feature, as you know if you've read a little about distributed version control. The downside is that the history becomes a maze of twisty little passages. Benjamin Smedberg's demo shows the history of a repository with lots of merges (each box is a check-in; you can click on the boxes to move around).
There have been a couple attempts at showing history in an intuitive, graphical way. Mercurial comes with a web UI for browsing the repository, including history (here's what it looks like). It also comes with an "hg glog" extension that draws history as ASCII art, and an "hg view" extension that does roughly the same thing with a little GUI. Sadly, none of these applications qualifies as awesome.
The project's goal is to rectify this sad situation by writing an awesome browser-based UI for navigating Mercurial repository history.

Project Details
v0.1 Release Details
-
to get pushloghtml working on my machine (some progress made on this part) -
to locate the source files that dictate the amount of pushlog entries that get displayed and then alter it to display more entries-
Turns out that there was some miscommunication and I need to add an AJAX scrolling feature that dynamically loads more changesets
-
-
to add code that allows expand/collapse functionality (apparently all I need is a js lib according to humph)-
Turns out that there was another miscommunication as Ted has already added this feature. Look here. However the patch has some problems that will need to be fixed. I might fix this for my 0.2 release (undecided for now)
-
To release v0.1 on time
v0.2 Release Details (More Information) (Final result)
-
To continue work on bug 459727-
Implement a loader GIF(View here) -
Getting the correct Chronological order when adding more entries OnScroll (View here)(Final result) -
Getting merge changesets to show up correctly when adding more entries OnScroll (View here)(final result)-
Making sure the new entries that load OnScroll comply with bug 445560 (Expand/Collapse feature) ==> REMOVED from v0.2 - this functionality should wait until the expand/collapse functionality itself is approved and goes live. This should be a separate bug
-
-
To make buglinks work -
To make changeset links work -
To get the correct date formating -
On first page load show 20 entries instead of 10(View here) -
To get the correct author names (right now, sometimes it returns the email address while other times the name of the author)(View solution here)
-
-
To fix ted's patch for bug 445560(View here) -
To implement "the which files were touched by a changeset" feature for bug 448707(View here)
v0.3 Release Details (View here)
-
Problem with my patch for bug 445560(View here)-
Fixed problems with my patch by adding 2 new patches(View here)-
Fix 1: Should use ids instead of dates -
Fix 2: Should store unique identifiers in the class instead of the id of the tag
-
-
- My patch for bug 448707 approved! (View here)
-
Implementing the Graph view for the pushlog-
Downloading Dirkjan's (djc) Graph view's source code(View here) -
Getting djc's Graph view running on my computer (localhost) with hg serve(View here) -
Understanding how djc's Graph view works(View here) (View here 2) -
Coding the Graph view for the pushlog
-
-
Problem with my patch for bug 459727(View here) (fix for my patch)-
To calculate the max use SELECT COUNT(*) FROM ... instead of asking for all the rows and then counting them -
getMaxEntries called, then 'start' used once the user scrolls. But the user might scroll before the first result comes back, while start is still zero -- a race condition. -
The JS code isn't consistently indented -
Patch seems to contain some non-ASCII characters. Bugzilla doesn't render it properly. Consider using an HTML entity reference, like – or —, instead of an actual Unicode character. -
In a few places the b tag is used where the server uses the strong tag; be consistent -
Loads more results when the user scrolls. What if the initial results don't fill up the window? -
Better to move CSS and formatting to stylesheets where possible
-
-
Problem #1 explained in comment #9 by jorendorff still existed with my new patch(it is fixed, view here) -
Improved the bug link feature for bug 459727(View here) - My patch for bug 445560 approved! (View here)
- v0.3 complete!
