gitweb has long had a feature where the user can click on any commit the blame display and go visit that commit's information page. From the user could go get the blame display for the file they are tracking, and try to digg through the history of any part of the code they are interested in seeing. We now offer somewhat similiar functionality in git-gui. The 4 digit commit abreviation in the first column of our blame view is now offered as a hyperlink if the commit isn't the one we are now viewing the blame output for (as there is no point in linking back to yourself). Clicking on that link will stop the current blame engine (if still running), push the new target commit onto the history stack, and restart the blame viewer at that commit, using the "original file name" as supplied by git-blame for that chunk of the output. Users can navigate back to a version they had been viewing before by way of a back button, which offers the prior commits in a popup menu displayed right below the back button. I'm always showing the menu here as the cost of switching between views is very high; you don't want to jump to a commit you are not interested in looking at again. During switches we throw away all data except the cached commit data, as that is relatively small compared to most source files and their annotation marks. Unfortunately throwing this per-file data away in Tcl seems to take some time; I probably should move the line indexed arrays to proper lists and use [lindex] rather than the array lookup (usually lists are faster). We now start the git-blame process using "nice", so that its priority will drop hopefully below our own. If I don't do this the blame engine gets a lot of CPU under Windows 2000 and the git-gui user interface is almost non-responsive, even though Tcl is just sitting there waiting for events.
