= Viewing Revision Logs =[[TracGuideToc]]When you browse the repository, it's always possible to query the ''Revision Log'' view corresponding to the path you're currently seeing.This will display a list of the most recent changesets in which the current path or any other path below it has been modified.== The Revision Log Form ==It's possible to set the revision at which the revision log shouldstart, using the ''View log starting at'' field. An empty valueor a value of ''head'' is taken to be the newest changeset. It's also possible to specify the revision at which the log shouldstop, using the ''back to'' field. By default, it's left empty, which means the revision log will stop as soon as 100 revisions have been listed.Also, there are three modes of operation of the revision log.By default, the revision log ''stops on copy'', which means that whenever an ''Add'', ''Copy'' or ''Rename'' operation is detected, no older revision will be shown. That's very convenient when workingwith branches, as one only sees the history corresponding to whathas been done on the branch.It's also possible to indicate that one wants to see what happenedbefore a ''Copy'' or ''Rename'' change, by selecting the ''Follow copies'' mode. This will cross all copies or renames changes.Each time the name of the path changes, there will be an additionalindentation level. That way, the changes on the different pathsare easily grouped together visually.It's even possible to go past an ''Add'' change, in order to see if there has been a ''Delete'' change on that path, before that ''Add''. This mode corresponds to the mode called ''Show only adds, moves and deletes''. While quite useful at times, be aware that this operation is quite resource intensive.Finally, there's also a checkbox ''Show full log messages'',which controls whether the full content of the commit log messageshould be displayed for each change, or only a shortened version of it.== The Revision Log Information ==For each revision log entry, there are 7 columns shown: 1. The first column contains a pair of radio buttons and should used     for selecting the ''old'' and the ''new'' revisions that will be     used for [wiki:TracRevisionLog#viewingtheactualchanges viewing the actual changes]. 2. A color code (similar to the one used for the [wiki:TracChangeset#ChangesetHeader changesets])     indicating kind of change.    Clicking on this column refreshes the revision log so that it restarts    with this change. 3. The '''Date''' at which the change was made. 4. The '''Revision''' number, displayed as `@xyz`.     This is a link to the TracBrowser, using that revision as the base line. 5. The '''Changeset''' number, displayed as `[xyz]`.    This is a link to the TracChangeset view. 6. The '''Author''' of the change. 7. The '''Log Message''', which contains either a summary or the full commit     log message, depending on the value of the ''Show full log messages''     checkbox in the form above.    == Inspecting Changes Between Revisions ==The ''View changes...'' buttons (placed above and below the listof changes, on the left side) will show the set of differencescorresponding to the aggregated changes starting from the ''old''revision (first radio-button) to the ''new'' revision (secondradio-button), in the TracChangeset view.Note that the ''old'' revision doesn't need to be actually ''older'' than the ''new'' revision: it simply gives a basefor the diff. It's therefore entirely possible to easily generate a ''reverse diff'', for reverting what has been donein the given range of revisions.Finally, if the two revisions are identical, the correspondingchangeset will be shown (same effect as clicking on column 5).== Alternative Formats ===== The ChangeLog Text ===At the bottom of the page, there's a ''ChangeLog'' linkthat will show the range of revisions as currently shown,but as a simple text, matching the usual conventions for!ChangeLog files.=== RSS Support ===The revision log also provides a RSS feed to monitor the changes.To subscribe to a RSS feed for a file or directory, open itsrevision log in the browser and click the orange 'XML' icon at the bottomof the page.
