<div class="section" id="motivation"> |

<h1><a class="toc-backref" href="#id12" name="motivation">Motivation</a></h1> |
| 71 |
<p>By offering a choice of version control systems, developers who want or need |
| 72 |
certain features, can choose which one suits them or their project the best.</p> |
| 73 |
<p>In addition, there are quite a few projects that should be Gentoo hosted, but |
| 74 |
are hosted elsewhere due to the fact that Subversion is not currently offered. |
| 75 |
Examples include the app-vim/gentoo-syntax package (<a class="footnote-reference" href="#id6" id="id1" name="id1">[1]</a>), and |
| 76 |
app-shells/gentoo-bashcomp (<a class="footnote-reference" href="#id7" id="id2" name="id2">[2]</a>).</p> |
| 77 |
<p>Subversion has many advantages over CVS, including changesets, directory |
| 78 |
versioning, atomic commits, versioned metadata, and more efficient branching |
| 79 |
and tagging (<a class="footnote-reference" href="#id8" id="id3" name="id3">[3]</a>). Despite these advantages, many developers feel that |
| 80 |
Subversion is not yet ready for the main tree due to scaling issues.</p> |
| 81 |
</div> |
| 82 |
<div class="section" id="specification"> |
| 83 |
<h1><a class="toc-backref" href="#id13" name="specification">Specification</a></h1> |
| 84 |
<p>The following steps describe, in detail, the process of setting up the |
| 85 |
Subversion svnserve daemon (over SSH) and creating new repositories.</p> |
| 86 |
<p>One repository should be created per project. Reasons for this include easier |
| 87 |
control over who has access, performance (checking out one big repository |
| 88 |
takes many times longer), ease-of-use (branching and merging are more difficult |
| 89 |
with one big repository), and meaningful revision numbers (since Subversion |
| 90 |
uses repository-global revision numbers, revision numbers for project A will |
| 91 |
increase on every commit even if no changes are made to project A).</p> |
| 92 |
<p>For preexisting CVS repositories, instructions on converting (<a class="footnote-reference" href="#id9" id="id4" name="id4">[4]</a>) are |
| 93 |
already available in addition to the cvs2svn documentation itself (<a class="footnote-reference" href="#id10" id="id5" name="id5">[5]</a>).</p> |
