support for patches list
Often as maintainer of RVM I have to work with multiple ruby patches, but it's hard to tell what patches were used for compiling ruby. As a temporary solution I have started using a file
patches.list in the root of source and installation directory. It would be nice if Ruby would include this list also in RbConfig::CONFIG.
Here is example content of the file I have for ruby-1.9.3-p362:
If that would be implemented I could understand if it would be required the files to be URLs to online patches which can be easily downloaded and analyzed.
#2 [ruby-core:51481] Updated by Michal Papis about 4 years ago
this is code used in RVM to populate (and use) the list https://github.com/wayneeseguin/rvm/blob/825aa97e7ea440b4cd3b8e5c3a6888b09498e0fd/scripts/functions/manage/base#L113-L125
it's all done before configuring ruby so the configure script could read the list and then make it available in RbConfig, of course this could be also easier done with environment variable like:
It does not give any real functionality improvement but helps to identify if there were any patches to the ruby that is ran, it is useful with RVM binary rubies or with distribution provided rubies.
