This includes Perforce Staff and contributors from the general public.</p> </div> </div> </div> <div class="sect1"> <h2 id="_terminology">Terminology</h2> <div class="sectionbody"> <div class="ulist"> <ul> <li> <p><em>GA Release</em>: A General Availability (GA) release is the first release of a new major version. It includes a new SDP tarball as well as updates to files available on the web site with standard/published links.</p> </li> <li> <p><em>Hot Fix</em>: A <em>hot fix</em> is change made in a release stream that does not involve generating a new SDP tarball. This can be done to push documentation changes to make documentation changes available faster between releases on the live web site, though does not update documentation available. A hot fix can also be done to make individual files available for 'curl' on the site without affecting the version available in the tarball. This usage should be rare and only used in exceptional circumstances where it is acceptable for files on the site to differ from those in the tarball. If contemplating a hot fix involving scripts, a Patch is generally the preferred approach.</p> </li> <li> <p><em>Merge Down, Copy Up</em>: A mantra for a well-designed release process. See the <a href="https://workshop.perforce.com/projects/perforce_software-pds">Perforce Directory Standard (PDS)</a> for information about this.</p> </li> <li> <p><em>Patch Release</em>: A Patch Release is functionally identical to a GA release, in that it includes a new SDP tarball and updates to files on the web site. Any SDP release between major version releases of the P4 Server is a Patch.</p> </li> <li> <p><em>Ready 5</em>: The property of a release process that ensures the team can always shift priorities and ship a patch quickly, even as various development tasks are in different states of readiness. Doing work properly and keeping the <code>mainline</code> clear of work that is not ready to ship is key to maintaining readiness.</p> </li> </ul> </div> </div> </div> <div class="sect1"> <h2 id="_script_versioning">Script Versioning</h2> <div class="sectionbody"> <div class="paragraph"> <p>Many individual SDP scripts are versioned using the <code>+k</code> "keyword expansion" file type modifier. This file type modifier causes the P4 Server to update keywords in the content of the versioned file, e.g. our scripts, with a new version identifier each time the script is submitted.</p> </div> <div class="paragraph"> <p>Scripts that use this versioning method support the <code>-V</code> (version check) option, which gives results like these examples:</p> </div> <div class="literalblock"> <div class="content"> <pre>$ ccheck.sh -V ccheck.sh version r25.1.32499</pre> </div> </div> <div class="literalblock"> <div class="content"> <pre>$ ccheck.sh -V ccheck.sh version DEV_C2S.31580</pre> </div> </div> <div class="paragraph"> <p>Due to the way we are using Streams, the path to the versioned file contains meaningful information about which version of SDP the script is released with. For example, if the script path starts with <code>//p4-sdp/r25.1</code>, that script is part of the SDP 2025.1 release. Released versions of SDP align with the P4 Server format of <code>rXX.Y</code>, where <code>XX</code> is a year identifier and <code>Y</code> increments with each release in a year. Unreleasd versions, such as those being developed and tested, use an ALL-UPPERCASE form of the development stream name, .e.g. DEV_C2S relates to the <code>//p4-sdp/dev_c2s</code> development stream. The uppercase is used to emphasize that version is not released.</p> </div> <div class="paragraph"> <p>The number at the end is the changelist number of the individual change that produced that latest version of the script. For released versions, this changelist will be due to release-process related activities rather the development code changes.</p> </div> <div class="paragraph"> <p>The following standard block of code (bash in this example) illustrates how the keyword is used to automatically update the version number with each submit.</p> </div> <div class="literalblock"> <div class="content"> <pre># Version ID Block. Relies on +k filetype modifier. #------------------------------------------------------------------------------ # shellcheck disable=SC2016 declare VersionID='$Id: //p4-sdp/r25.1/doc/gen/gen_script_man_pages.sh#2 $ $Change: 31472 $' declare VersionStream=${VersionID#*//}; VersionStream=${VersionStream#*/}; VersionStream=${VersionStream%%/*}; declare VersionCL=${VersionID##*: }; VersionCL=${VersionCL%% *} declare Version=${VersionStream}.${VersionCL} [[ "$VersionStream" == r* ]] || Version="${Version^^}"</pre> </div> </div> <div class="paragraph"> <p>The line that defines <code>VersionID</code> is modified by the P4 Server upon submit, with the '$Id:$` and <code>$Change:$</code> tags being replaced. This ensures that the version is reliably updated each time the script changes. Note that in this bash example, single quotes are used rather than double quotes to prevent the bash shell from interpreting <code>$Id</code> and <code>$Change</code> as bash script variables. The <code>shellcheck disable=SC2016</code> comment silences as ShellCheck warning about accidental usage of single quotes suppressing expansion of variables. In this case, that is exactly the intent.</p> </div> </div> </div> <div class="sect1"> <h2 id="_working_in_streams">Working in Streams</h2> <div class="sectionbody"> <div class="paragraph"> <p>Different types of work are done in different streams:</p> </div> <table class="tableblock frame-all grid-all stretch"> <colgroup> <col style="width: 24%;"> <col style="width: 15%;"> <col style="width: 61%;"> </colgroup> <thead> <tr> <th class="tableblock halign-left valign-top">Stream Name</th> <th class="tableblock halign-left valign-top">Type</th> <th class="tableblock halign-left valign-top">Description of Work</th> </tr> </thead> <tbody> <tr> <td class="tableblock halign-left valign-top"><div class="content"><div class="paragraph"> <p><code>//p4-sdp/r*</code><br> Examples:<br> <code>//p4-sdp/r25.1</code><br> <code>//p4-sdp/r25.2</code></p> </div></div></td> <td class="tableblock halign-left valign-top"><div class="content"><div class="paragraph"> <p><code>release</code></p> </div></div></td> <td class="tableblock halign-left valign-top"><div class="content"><div class="paragraph"> <p>Release process activities are done in release streams, such as updating the Version file and generating final versions of docs and Release Notes.
