-
增强提案文档,Jonathan 有笔记,稍后今天会整理出来。
-
治理文档 - 欢迎帮助。还有“who's who”或“关于”页面。https://conda-forge.github.io/#about
* This page could be expanded, should mentioned these meeting.
-
从议程中移除事项
* Prioritize items on agenda which we should/must talk about.
- 交叉链接事项到 GitHub issues/讨论
-
状态页面:https://conda-forge.github.io/status/
* Linked to "status" repo: [](https://github.com/conda-forge/status)[https://github.com/conda-forge/status](https://github.com/conda-forge/status)
-
conda-forge 代码行为准则 - Filipe 仍在努力
-
许多团队正在研究新的构建系统:Filipe,Phil,Continuum
* Continuum's plan would allow others to add build workers, perhaps conda-forge could use these in addition to the CI services, especially for long builds
- 组织新的会议来讨论这个话题
-
开源 Anaconda Build,我们应该推动发布吗?
* Would be helpful to have our own build system rather than being dependent on CI systems.
-
如果我们降低并发性,Travis CI 可以增加时间
* Can we switch between longer time and concurrency? How much work is this?
- 可能目前不接受该提议
- 最好在某处找到可信的硬件
- 用于 OS X 构建的 Vagrant,我们可以研究一下
-
安全
* If user changes name and someone takes old name can be a security issue: [](https://groups.google.com/forum/#)[https://groups.google.com/forum/#](https://groups.google.com/forum/#%21topic/rustlang-security-announcements/BK_3gbXhSn4)[!topic/rustlang-security-announcements/BK_3gbXhSn4](https://groups.google.com/forum/#%21topic/rustlang-security-announcements/BK_3gbXhSn4)
- 可以通过使用唯一的用户 ID 而不是 GitHub 用户名来解决
- 想要 Anaconda.org 的令牌,允许写入单个软件包(Phil 将推动 Continuum 处理此事),而不是全局写入。
-
元数据统一
* Should conda-forge include additional metadata which would make it easier for Continuum to re-use recipes
-
这应该是必需的还是可选的?
* Required would likely reduce number of contributors
-
将需要时间/工作来将这些添加到所有当前软件包
-
添加到 linter 和 conda skeleton
* Make linter have "warnings" not hard fails
-
其中许多似乎是冗余的,我们可以重用现有的元数据吗?
-
-
许可证文件可能应该是必需的
* Legal vs. suggested
-
议程
-
将议程事项标记为完成。
-
分享状态页面。:) 还要弄清楚如何有效地定向通知。
-
增强提案文档更新。
-
conda-forge 代码行为准则文档:https://docs.google.com/document/d/10dxX0Zse0Rx1HqsxC73Wfsghmy5m8PP8cHuBIOhWKpc/edit
-
提及 Travis-CI 提供更多 CI 时间。
-
我们可以考虑将您的构建时间增加到 180 分钟,但我们可能需要将您的默认并发数从 5 个作业减少到 3 个,因为您将在很长一段时间内使用多个虚拟机。
-
提及/讨论 Travis Oliphant 关于开源 Anaconda Build CI 的评论。
-
安全
-
Feedstocks 哲学:显式与隐式 / 可重现与冗余
-
与 Continuum 的元数据统一 - 我们是否可以接受在 about 部分添加一些字段以匹配 Anaconda 标准?
-
包含许可证文件
-
许多配方不包含许可证文件。
-
几乎每个许可证都有关于提供许可证的条款。
-
我们是否应该开始要求这个字段。
-
注意一些开发者也没有包含许可证文件。
-
在某些情况下,让他们这样做很困难。
-
CUDA/cuDNN 更新
-
改进基础设施
* Better workflows with staged-recipes
* Fast finish AppVeyor on merge ( [conda forge/staged recipes#1142](https://github.com/conda-forge/staged-recipes/pull/1142) )
* Drop Travis CI matrix ( [conda forge/staged recipes#1234](https://github.com/conda-forge/staged-recipes/pull/1234) )
* Use CircleCI for feedstock generation ( [conda forge/staged recipes#916](https://github.com/conda-forge/staged-recipes/issues/916) )
* Keeping recipes out of PRs ( [conda forge/staged recipes#942](https://github.com/conda-forge/staged-recipes/issues/942) )
* Bank work in partial conversion ( [conda forge/staged recipes#915](https://github.com/conda-forge/staged-recipes/issues/915) ) -
通知(我们如何掌握它们)
-
MSYS2
* Available on defaults - was in conda 4.1.7, but that was pulled. Coming in 4.1.8.
- 讨论 Ray Donnelly 在 MSYS2 软件包方面的工作,以及我们希望如何使用这些软件包并将它们集成到 conda-forge 中。
- 需要考虑的一些用例 OpenBLAS,FFTW,构建工具,其他?
-
二进制数据
* Do we include it in recipes?
- 如果允许(例如图标),我们允许哪些类型?
- 我们如何验证许可?
- 我们如何验证它们是安全的?
-
开发版本:它们在哪里发布?
* Do we do them at conda-forge?
* Maybe add a label.
* Do we let others do them with a feedstock on their own repo?- 我们如何执行我们决定的任何事情?
-
频道镜像
* Can this point be a little bit explained? I thought about this as well and would like to contribute to this point.
* Eric Dill has put together a script for copying a package from one channel to another here: [conda forge/conda forge.github.io#134](https://github.com/conda-forge/conda-forge.github.io/pull/134)
* I have a really, really crude script that copies all of the packages in one channel to another that I just put at: [](https://gist.github.com/mwcraig/8473cf840f6d29236d6d8af699404555)[https://gist.github.com/mwcraig/8473cf840f6d29236d6d8af699404555](https://gist.github.com/mwcraig/8473cf840f6d29236d6d8af699404555)
* conda-build-all can copy from one channel to another: `conda build-all --inspect-channels conda-forge --upload-channels astropy some_packge_recipe` will copy the `some_package` from the channel conda-forge to astropy if it can, or build it if it doesn't exist on conda-forge. Discussion about what the desired behavior should be has started at: [SciTools/conda build all#46](https://github.com/SciTools/conda-build-all/issues/46) -
Feedstock 历史
* Is it sacred?
-
我们是否 rebase/force push?
* If so, under what conditions?
-
我们如何避免多人同时执行此操作?
* I don't think you can.
* IMHO, if it's just one author in staged recipes, sure. If feedstock, no force push - only to PRs to feedstock. If people don't mind merge PRs, it sure is a lot simpler to not rebase. I have messed up rebasing a few times recently... =(

-
Continuum 元数据请求:我们可以将这些添加到 linter 吗?
* example metadata: [](https://github.com/ContinuumIO/anaconda-recipes/blob/master/anaconda-build/meta.yaml#L36-L44)[https://github.com/ContinuumIO/anaconda-recipes/blob/master/anaconda-build/meta.yaml#L36-L44](https://github.com/ContinuumIO/anaconda-recipes/blob/master/anaconda-build/meta.yaml#L36-L44)
- 此外,区分摘要(限制为 77 或 80 个字符)与描述(无限制)
- Anaconda verify:最好在中间会合,而不是分歧。conda-build 可能会集成 anaconda-verify,如果 conda-forge 在此处添加元数据会很好。
-
删除 numpy 1.10 并减少我们的构建矩阵。(Numba 现在适用于 numpy 1.11。)
-
软件包签名
* Should be easy to do. ( [](http://conda.pydata.org/docs/signed-packages.html)[http://conda.pydata.org/docs/signed-packages.html](http://conda.pydata.org/docs/signed-packages.html) )
- 以前对此有一些兴趣。
-
HTTPError: 503 服务器错误:服务不可用:后端服务器已满,网址为...
* Seems we are regularly running into this issue under normal usage conditions.
- 之前讨论过在 AppVeyor 上缓存软件包并尝试重用这些软件包开始。
- 也许我们需要考虑在所有 CI 上缓存。
- 通过
constructor
构建我们自己的类似 Miniconda 的自解压脚本,其中包含软件包。 - Continuum 方面已经有所改进,应该对此有所帮助。简而言之,repodata(给定频道的软件包索引)是为每个 anaconda.org 查询生成的。这是不必要的高成本,并且已经实施了一些缓存方案。
-
处理删除未固定/错误固定的软件包。
* Has been done manually thus far.
- 但这不能很好地扩展。
- 我们应该(半)自动化删除吗?
- 我们应该热修复损坏的软件包吗? ( conda forge/conda forge.github.io#170 )
- 我们应该将它们标记为损坏
-
当前不可构建的软件包
* In particular open source code that is out of scope for CIs.
-
示例包括 Qt4,Qt5,可能 PyQt4,可能 PyQt5,gcc,VTK 等。
-
我们如何指示它们是手动构建的?
-
我们是否可以接受上传非构建的二进制文件?
-
我们何时确定某件事可以手动构建?
-
人们在手动构建时应遵循哪些程序?
* Use a standard build docker image, VM, or vagrant file
-
签名软件包?
-
在可行的情况下实施可重现的构建(linux)
* [](https://reproducible-builds.org/)[https://reproducible-builds.org/](https://reproducible-builds.org/)
-
我们需要在 conda-smithy 其他地方进行哪些更改?
-
-
我们还可以利用哪些其他构建基础设施?
* Would be nice to provide some volunteer builder abstraction, so that we could have an elastic worker farm that would be somewhat resilient.
- 标准化构建镜像可能(相对)容易 - 但如何协调呢?
-
-
Windows BLAS 解决方案
* Still don't have a BLAS for Windows yet need something.
-
不构建 BLAS
* NumPy has a small subset of BLAS functionality.
-
不确定如何处理 SciPy(也无法找到它们的 Windows wheels)。
-
仅使用 C 支持构建 OpenBLAS。
* Will be pretty slow.
-
应该适用于所有 Python。
-
使用 MinGW 编译器构建 OpenBLAS。
* Works with Python 2.7 and 3.4.
-
不适用于 Python 3.5?
-
重用类似于 R 的 BLAS 的东西。
* Is there a package for something like this?
-
它是否会遇到与 Python 3.5 相同的问题?
-
ATLAS?
