     1= Viewing Revision Logs =
     2[[TracGuideToc]]
     3
     4When you browse the repository, it's always possible to query the
     5''Revision Log'' view corresponding to the path you're currently seeing.
     6This will display a list of the most recent changesets in which the
     7current path or any other path below it has been modified.
     8
     9== The Revision Log Form ==
     10
     11It's possible to set the revision at which the revision log should
     12start, using the ''View log starting at'' field. An empty value
     13or a value of ''head'' is taken to be the newest changeset.
     14
     15It's also possible to specify the revision at which the log should
     16stop, using the ''back to'' field. By default, it's left empty,
     17which means the revision log will stop as soon as 100 revisions have
     18been listed.
     19
     20Also, there are three modes of operation of the revision log.
     21
     22By default, the revision log ''stops on copy'', which means that
     23whenever an ''Add'', ''Copy'' or ''Rename'' operation is detected,
     24no older revision will be shown. That's very convenient when working
     25with branches, as one only sees the history corresponding to what
     26has been done on the branch.
     27
     28It's also possible to indicate that one wants to see what happened
     29before a ''Copy'' or ''Rename'' change, by selecting the
     30''Follow copies'' mode. This will cross all copies or renames changes.
     31Each time the name of the path changes, there will be an additional
     32indentation level. That way, the changes on the different paths
     33are easily grouped together visually.
     34
     35It's even possible to go past an ''Add'' change, in order to see
     36if there has been a ''Delete'' change on that path, before
     37that ''Add''. This mode corresponds to the mode called
     38''Show only adds, moves and deletes''.
     39While quite useful at times, be aware that this operation is quite
     40resource intensive.
     41
     42Finally, there's also a checkbox ''Show full log messages'',
     43which controls whether the full content of the commit log message
     44should be displayed for each change, or only a shortened version of it.
     45
     46== The Revision Log Information ==
     47
     48For each revision log entry, there are 7 columns:
     49 1. The first column contains a pair of radio buttons and should be used
     50    for selecting the ''old'' and the ''new'' revisions that will be
     51    used for [wiki:TracRevisionLog#viewingtheactualchanges viewing the actual changes].
     52 1. A color code (similar to the one used for the
     53    [wiki:TracChangeset#ChangesetHeader changesets]) indicating kind of change.
     54    Clicking on this column refreshes the revision log so that it restarts
     55    with this change.
     56 1. The '''Revision''' number, displayed as `@xyz`.
     57    This is a link to the TracBrowser, using the displayed revision as the base line.
     58 1. The '''Changeset''' number, displayed as `[xyz]`.
     59    This is a link to the TracChangeset view.
     60 1. The '''Date''' at which the change was made.
     61    The date is displayed as the time elapsed from the date of the revision. The time
     62    elapsed is displayed as the number of hours, days, weeks, months, or years.
     63 1. The '''Author''' of the change.
     64 1. The '''Log Message''', which contains either the truncated or full commit
     65    log message, depending on the value of the ''Show full log messages''
     66    checkbox in the form above.
     67   
     68
     69== Inspecting Changes Between Revisions ==
     70
     71The ''View changes...'' buttons (placed above and below the list
     72of changes, on the left side) will show the set of differences
     73corresponding to the aggregated changes starting from the ''old''
     74revision (first radio-button) to the ''new'' revision (second
     75radio-button), in the TracChangeset view.
     76
     77Note that the ''old'' revision doesn't need to be actually
     78''older'' than the ''new'' revision: it simply gives a base
     79for the diff. It's therefore entirely possible to easily
     80generate a ''reverse diff'', for reverting what has been done
     81in the given range of revisions.
     82
     83Finally, if the two revisions are identical, the corresponding
     84changeset will be shown (same effect as clicking on the !ChangeSet number).
     85
     86== Alternative Formats ==
     87
     88=== The !ChangeLog Text ===
     89
     90At the bottom of the page, there's a ''!ChangeLog'' link
     91that will show the range of revisions as currently shown,
     92but as a simple text, matching the usual conventions for
     93!ChangeLog files.
     94
     95=== RSS Support ===
     96
     97The revision log also provides a RSS feed to monitor the changes.
     98To subscribe to a RSS feed for a file or directory, open its
     99revision log in the browser and click the orange 'XML' icon at the bottom
     100of the page. For more information on RSS support in Trac, see TracRss.
