Plante Linden Customisé
Argent Stonecutter a remarqué que très peu de données definissent les arbres et les plantes utilisées dans Second Life. L'object entier pourrait etre specifié dans une liste et deployés de la même manière que sont deployés les particules. Cela offre la possibilité d'avoir plus de controle, via les scripts, sur les plantes et de reduire le nombre de prims utilisés. Vous pouvez trouver les détails sur le wiki (en anglais) Custom Linden Plants et sur JIRA a VWR-303.
Modérer les logs du client
Tom "Spot" Callaway à exprimé son intérêt à réduire la quantité de log généré par le client. Il a trouvé une référence à logcontrol.xml et logcontrol-dev.xml mais il n'a pas pu trouver d'exemple de leurs utilisations. Ryan Williams (Linden) a écrit une page sur Error Logging System. Phoenix Linden fait remarquer que la librairie openJPEG est la plus verbeuse car elle écrit directement sur stderr, ce qui outrepasse le systeme de gesion de log. Phoenix indique aussi qu'un correctif devrait être apporté sous peu. "Guido" indique que VWR-100 montre comment désactiver les logs d'openJPEG en attendant.
Calmer les discussions
La discussion continue sur le meilleur moyen de gerer les sujet generant un fort traffic. Pour l'instant, Rob Lanphier (Linden) a demandé aux utilisateurs de creer une entrée JIRA ou d'utiliser les pages de discussion wiki (talk page). Une discussion a cependant continué a propos de l'interet des talk page sur SLDev Talk page. Rob a expliqué certains benefices a utiliser le wiki pour cela, incluant le fait que certains sujets seront encore discutés pour les mois et années a venir. Il donne l'exemple de texture cache discussion qui refera certainement surface dans le futur.
Rob a aussi parlé du problème des discussion qui semblent êtres plus le sujet d'un amusement que d'un travail constructif. Cela arrive souvent quand quelqu'un parle d'un sujet ou une idée sans avoir l'intention d'écrire du code et que d'autres, sans intention de programmer, prennent position sur un long débat sans pourtant produire quoi que ce soit.
A propos de la séparation des sujet vers le JIRA et le wiki, certains membres ont protestés contre cette idée et ont proposés de tout garder sur la liste, d'utiliser des forums, ou plusieurs mailling lists. La discussion a aussi continuée in-world, l'idée d'une list limitée aux contributeurs qui ont signés un agrement avec LL a refait surface, ainsi que l'idée de poster des sommaires de certaines discussions in-worl sur la liste.
Aucune concensus n'a été trouvé. Mais Rob a demandé aux participants d'essayer tout de même sa proposition pendant quelques semaines. Pendant son office du lundi, rob a rapporté qu'il n'a pas encore eu de retour de la part des developpeurs Linden a propos des guides d'utilisation de la list.
Un point unanime est que le systeme de notification par mail du wiki doit être reparé.
One point with unanimous agreement is that the Wiki's email notification signup system needs to be fixed. During Rob's office hours, Soft noted that if it were possible to receive an email about every change on a subscribed item, it would be functionally identical to the mailing list for those who favor the list's push format.
(One note - if these discussions continue in the Wiki, people need to be better about signing comments. SLDev's Talk page was very hard to read. -- Soft)
Controlling the Build Mode
Ettore Pasquini expressed interest in learning how the mouse and keyboard control the build mode. Specifically, Ettore is looking for "which classes or functions take care of movements." Ettore is interested in hooking up a 3D controller for use in controlling build mode with high precision.
There was some discussion about available controllers and even a link to a driver for using a Wiimote as an input device but to date, Ettore has no answer.
More mingw Cross-Build Work
Dzonatas Sol posted another patch for building the Windows viewer using mingw. The new patch does not appear to be attached to an existing JIRA entry, although Dzonatas mentions that it addresses VWR-186, VWR-187 and VWR-198. This patch was made against First Look 58390.
Disconnected Without Warning
Laurent Laborde noted that the user is not explicitly warned when the current simulator times out and disconnects. Callum Lerwick notes that his wife has lost hours worth of work in continuing to make changes to objects without realizing that the map has gone red. Callum suggested that an explicit dialog warning about the disconnection would work if somehow saving the data for later upload or immediately reconnecting were infeasible. Erik Anderson advocates an immediate reconnection, noting that less capable systems can take minutes to relog.
GPL v3 Released
Dzonatas Sol noted that third draft GPL has been released. Of particular interest, the third draft removes language that required copyright holders to protect downstream licensees from patent infringements. "There is now an overall clarification of how a covered work is conveyed and when one conveys such a work that one must abide by the terms of the license to disclaim patent infringement or likewise." Dzonatas indicated the wiki would be updated when more was known about these changes.
OpenJPEG - Bigger, Better, Stronger, Faster
Callum Lerwick found a loop where an array was being zeroed in row order instead of column order. James Cook (Linden) noted that a memset would work even better than correcting the order here, as memset was guaranteed to be optimized for each platform. Stefan Westerfeld noted some work being done on cleaning up this code already and also noted the existence of an OpenJPEG optimization mailing list. Francois-Olivier Devaux, part of the OpenJPEG project, noted that a new version of OpenJPEG was imminent, and suggested that this fix could be included if someone offers a patch. Callum Lerwick followed up with a patch of work in progress.
Reading Others' Friendlists
Marco Milanesio inquired as to whether it was possible to read other users' friendlists. There were no helpful replies for Marco Milanesio. Whether this is possible remains unanswered, though Dale Glass expressed that he hoped it would never be possible.
GPG Keysigning
Dale Glass inquired as to whether there would be interest in LL GPG keysigning. He suggested that LL should create a master key used to sign all employees, as well as creating an automated signing mechanism running on the SL website which allowed signing against a player name or the registered account name. Dale went on to discuss various applications for the keys such as SLDev patch signing and eventual plugin signing. Dale also suggested that key trust levels could be used to differentiate between users with payment info on file, payment info used, Linden Lab employees, and so on.
Phoenix Linden noted that his key is available on his wiki page and via subkeys.pgp.net. Phoenix has signed many of the LL developer keys already and notes:
I will sign keys of people that I meet and that I prove to myself match their proposed email address. A secure and automated method of proving identity and key mappings would take a while, so no one is spending much time thinking about it. I will think about how to do this, and talk to Zero to see if there is a good way to roll that into our current Agent Domain scalability work. Until that time, I am the best gateway (aka bottleneck) for signing contributor keys.
Submitting Patches Requiring Translation Work
Jason Giglio asked what to do about patches that included new UI text.
Leyla Farazha (Linden) noted that contributors needed only make changes to the US English text. There is a process in place to detect what needs translation before release. Further:
Help with the translation process is always welcome, and once we have set up the pipeline for that work we'll let you all know. :-)
Jean Miller (Linden) requests that users please not include machine translations and noted that Linden Lab are putting together tools which would allow contributing translations for missing strings via the Wiki. Jean invited list members to contribute a snazzy format for such a wiki page.
Alissa Sabre, a native Japanese speaker, noted that the Japanese translation is very poor. Jean Miller indicated that the responsible translation service was no longer in use, and that LL were aware of cleanup work to be done here. Laurent Laborde was happier with the French version, "Not super-perfect, but good enough to be 100% useable."
Identifying JIRAs Needing Action
Rob Lanphier (Linden) previously indicated that list members could help tremendously by voting on issues needing attention. Some issues are still getting lost in the volume of the public JIRA however. During Rob's office hours, Gigs Taggart pointed to a few hot issues. It was also noted that it was possible to search for JIRAs with patches attached, and that these would be good high-priority candidates.
Rob indicated that LL are looking to hire someone who can help handle JIRAs and patches offered by the public.
Physics
During Rob Lanphier's (Linden) office hours, Soft Noel inquired about why LL was using an old version of Havok for physics in Second Life. Rob explained that much user content relied on quirks and precise behaviors of the older engine. Rob hoped that coming changes in SL that make it possible to do incremental rollouts might offer a step toward phasing in a faster engine.
Drewan Keats wondered if there had been any discussion about open source physics engines. There was no follow-up discussion on the point.
Adroit's Unit Testing Patches
Soft Noel asked if anyone had been using or testing Adroit's unit testing patches. Nobody in Rob Lanphier's office hours had any positive response, though Rob pointed to the unit testing framework in use as the tut-framework.
Rob Linden Needs a Bear
You can't have this many in-world meetings and not have a prize at the end, just in case a meeting actually turns out to be boring and all. "Oh hey, and look - FREE BEAR!" is a perfect save. Does SLDev have any qualified bear makers?
