From 244a70e608204a515c214a11c43f3ecf7642533a Mon Sep 17 00:00:00 2001 From: Luben Tuikov Date: Thu, 4 Jan 2007 18:37:45 -0800 Subject: [PATCH] Blame "linenr" link jumps to previous state at "orig_lineno" Blame currently displays the commit id which introduced a block of one or more lines, the line numbers wrt the current listing of the file and the file's line contents. The commit id displayed is hyperlinked to the commit. Currently the linenr links are hyperlinked to the same commit id displayed to the left, which is _no_ different than the block of lines displayed, since it is the _same commit_ that is hyperlinked. And thus clicking on it leads to the same state of the file for that chunk of lines. I.e. data mining is not currently possible with gitweb given a chunk of lines introduced by a commit. This patch makes such data mining possible. The line numbers are now hyperlinked to the parent of the commit id of the block of lines. Furthermore they are linked to the line where that block was introduced. Thus clicking on a linenr link will show you the file's line(s) state prior to the commit id you were viewing. So clicking continually on a linenr link shows you how this line and its line number changed over time, leading to the initial commit where it was first introduced.
