 v45 == Action Workflow === Follow-up #follow === Follow-up & Development plan {{{#!th '''Each action must have a wikipage and a ticket related to it'''. Browse to the current workplan page wiki/{YEAR}WP to create them and find the content and status of all planned actions in the workplan. '''Wiki''' In addition to the general informations of the action (subject, people involved, resources, ...), the wikipage will describe in details: * Implementation plan: scientific context with references, code modifications with modules/files/variables and documentation changes (reference manual, wiki, ...) * Validation results from list of tests to ensure the development produces the anticipated effects and doesn't not impact unexpectedly the operation of the code and its other components, see below * (Pre,Re)view finding: decision with motivated feedbacks __Please follow carefully the indications in 'Help' section to avoid issues when editing the wikipage and the form fields__. }}} {{{#!th The ticket will monitor the progress in the development and so it should be updated as the work goes on. In that regard, the commits with a clear reference to the ticket in the log message (#XXXX) will be listed in the 'Commit History' Section. '''Ticket''' Once the 1^st^ part of the wikipage is completed by PI (detailed implementation plan), the PI will submit it to Previewer. The Previewer will discuss with PI to reach full agreement on detailed implementation plan (in a maximum of 2 weeks starting from submission date). \\ The PI is responsible to give all requested details. The Previewer is responsible to check with all experts that implementation plan is indeed correct and compatible with the other developments going on in parallel during the year. Objective is to avoid the need for a full rewriting at the end (which did happen sometimes previously). }}} |- {{{#!td style="vertical-align: top" === Coding & Validation [[NewPage(id=WPAction, parent=wiki/2017WP, template=WorkPlanAction, placeholder=Wikipage name, button=Create action's wikipage)]] '' '''Reminder for wiki page name''': '{WG or INSTITUTE}-{NUM}_{PIS}-{KEYWORDS}' '' ==== Start the coding This page will permit to follow the ongoing work through different steps for explanation Please follow carefully the following indications: * '''Create review page from the root page of the yearly workplan wiki/{YEAR}WP''' * Once this last page is created, you do not need to edit it like a typical wiki page to complete the requested fields: just complete the fields in the writeable areas and click on "Submit" button at the end of the section to save your additions * Editing the page is only needed if your want to add some fields in the page. Activate the "side to side" button on top right of the page to facilitate this first edit and '''do not switch to 'wyziwig' view mode''' * The wiki page will describe: * Purpose, motivation and main tasks of the action * PI(S) & (P)Reviewer(s) name(s) * Detailed  implementation plan: scientific, technical and an expected summary  of changes for NEMO reference manual to be written later. * Detailed list of specific tests, see below * (P)Review status Once the Previewer has sent the green light (approval of development plan), the PI can created the corresponding development branch. This branch should be created from the up to date version of NEMO as chosen for each year (usually the trunk at a given revision, see minutes of NEMO System Team videoconferences or our local NEMO representative). }}} {{{#!td style="vertical-align: top" {{{#!html
}}} Development branches will be created on the SVN repository under the directory svn/nemo/branches/$YEAR. The pattern for the branch name is: dev_${forking revision number}_${workplan item}-${keyword(s)} (ex 'dev_r8329_ENHANCE14_SAL') \\to gather the group discussion. The form should set few fields ('Type': 'Development' and 'Milestone' to current WP) but others fields have to be set in a appropriate way: * 'Cc': add email(s) of people outside NEMO ST for further notification. * 'Component': the area the change is being targeted for. ==== Develop and document your change The other fields in the ticket (e.g. 'Priority', 'Keywords') should also be set appropriately. Development can progress on this new branch. A few things to bear in mind when developing your changes: }}} * Follow the appropriate coding standard, see NEMO coding standards document. Code should be documented on line as defined in the coding rules. * Ensure commit messages to your branch are meaningful, they are visible to everyone using the system. * Commit regularly and don't wait to have a certain amount of changes to do so, the debugging process will be easier with multiple small modifications by testing each revision one by one. * Changes in the reference manual should be also written as soon as possible, and before review process. Once the wiki page is completed by PI (detailed implementation plan), the PI will submit it to Previewer. The Previewer will discuss with PI to reach full agreement on detailed implementation plan (in a maximum of 2 weeks starting when PI submits wiki page to Previewer). \\ The PI is responsible to give all requested details. \\ The Previewer is responsible to check with all experts that implementation plan is indeed correct and compatible with the other developments going on in parallel during the year.  Objective is to avoid the need for a full rewriting at the end (which did happen sometimes previously) === Start the coding Once the Previewer has sent the green light (approval of detailed implementation plan and summary of changes in reference manual), the PI can created the corresponding  development branch. The branch should be created from the up to date version of NEMO as chosen for each year (usually the trunk at a give fixed revision for a give year, see minutes of NEMO System Team videoconferences.  Development can progress on this new branch. Each year, development branches will be created in the directory svn/nemo/branches/YEAR/"standard name of dev branch".\\ "standard name of dev branch" should be: dev_"starting revision number"_"workplan item_purpose" (ex 'dev_r1302_LOCEAN1_mpp') === Develop your Change A few things to bear in mind when developing your changes, * Follow the appropriate coding standard, see NEMO coding standards document. * Ensure commit messages to your branch are meaningful. They are visible to everyone using the system. * You don't have to commit to your branch to test a change. You can compile from a working copy. === Test your Change ==== Test your Change Test your change appropriately and record the results. The testing required will depend on the change and the potential impact on other configurations. When testing, things to consider include * full successful SETTE tests: to check nothing is broken or goes wrong in the reference configurations SETTE tests: if running with some changes in the results, those have to be justified and checked in detail. New code should not change results when it is switched off, and not alter results when tuned on. * full successful specific tests: to be defined before starting, in order to check that development does indeed what is expected ''In particular the Trusting tool has been developed in order to ease the validation all along the working on the code, not all in one with SETTE. The developer can regularly evaluate the changes for a any given configuration compared with benchmark results he has defined.'' === Document your Change * Progress in the development should be documented as the work goes on in the !ticket created at the beginning/ * Code should be documented on line as defined in the coding rules * Changes in the reference manual should be also written as soon as possible, and before review process * full successful SETTE tests: to check nothing is broken or goes wrong in the reference configurations SETTE tests: if running with some changes in the results, those have to be justified and checked in detail. New code should not change results when it is switched off, and not alter results when tuned on. * full successful specific tests: to be defined before starting, in order to check that development does indeed what is expected === Review The reviewer should check that th development did indeed meet what has been approved at Preview step * The code changes are understood and appropriately made. * The documentation is sufficient to understand the code change and its impacts. * The code changes are understood and appropriately made. * The documentation is sufficient to understand the code change and its impacts. The Reviewers completes the review part of wiki page with the PI. Once all light are green, the development is approved and can be merged for the new release of NEMO (merging back with the trunk is not described here).
