<p>This GLEP proposes addition of a new special package version suffix - <tt class="docutils literal">scm</tt> -
|
| 63 |
peper |
1.5 |
for ebuilds checking out source directly from a source code management system.</p>

<p>Currently there is no standard way of identifying SCM ebuilds. Using 9999 as the
|
| 68 |
peper |
1.5 |
version is pretty common, but it is handled like any other ebuild and hence
|
| 69 |
|
|
portage cannot provide any additional features for packages with such a version.
|
| 70 |
antarus |
1.7 |
Another way is adding a separate package with a -cvs suffix in its name, but
|
| 71 |
robbat2 |
1.8 |
that forces the author to use <tt class="docutils literal">|| ( cat/pkg <span class="pre">cat/pkg-cvs</span> )</tt> dependencies. The
|
| 72 |
|
|
closest to what is proposed in this GLEP is the <tt class="docutils literal">cvs</tt> version part, but its
|
| 73 |
antarus |
1.7 |
implementation is of very limited use. It has strange comparison rules, no
|
| 74 |
|
|
documentation, has been used sparingly (if ever) and has a misleading name.</p>
|
| 75 |
peper |
1.5 |
<p>The possibility for package managers to recognise SCM ebuilds would allow them
|
| 76 |
|
|
to add features dedicated specially to said ebuilds. One such feature could be
|
| 77 |
antarus |
1.7 |
automatic re-installation of SCM packages once a day or week. Any
|
| 78 |
|
|
specifications for such features are beyond the scope of this GLEP.</p>

<p>The addition of the scm suffix yields changes in version comparison:</p>
|
| 100 |
|
|
<blockquote>
|
| 101 |
|
|
<ul class="simple">
|
| 102 |
|
|
<li>When comparing version components from left to right the scm component has the
|
| 103 |
antarus |
1.7 |
highest priority over other version components. Hence
|
| 104 |
robbat2 |
1.8 |
<tt class="docutils literal"><span class="pre">pkg-1_alpha-r3</span> < <span class="pre">pkg-1-scm</span></tt>, 'scm' is greater than 'alpha-r3'.</li>
|
| 105 |
peper |
1.5 |
<li>Current suffixes with no number part no longer default to zero if they are
|
| 106 |
|
|
followed by an scm suffix. If that's the case the number part is considered
|
| 107 |
robbat2 |
1.8 |
to be of a maximum value. Hence <tt class="docutils literal"><span class="pre">1_alpha2-scm</span> < <span class="pre">1_alpha-scm</span></tt>, but still
|
| 108 |
|
|
<tt class="docutils literal">1_alpha == 1_alpha0</tt>. The rationale behind this choice is to allow
|
| 109 |
antarus |
1.7 |
multiple branches. For instance imagine a package with an alpha branch
|
| 110 |
|
|
and multiple scm releases, as the following: <tt class="docutils literal"><span class="pre">alpha-scm</span></tt>,
|
| 111 |
|
|
<tt class="docutils literal"><span class="pre">alpha2-scm</span></tt>, <tt class="docutils literal"><span class="pre">alpha3-scm</span></tt> and so forth. The desired outcome is
|
| 112 |
|
|
for <tt class="docutils literal"><span class="pre">alpha-scm</span></tt> to be greater than all other branches of the same tree.</li>
