| The standalone Dart executable uses the NSS library from Mozilla to |
| support secure networking connections (SSL and TLS). It uses a copy |
| of the library from the Chromium repository, that includes patches |
| added by Chromium. We pin this to a fixed revision, using the |
| nss_revision variable in all the DEPS files in the deps directory of |
| the Dart repository. |
| |
| This revision should be updated when new security fixes are added to |
| NSS, or every few months. The .gyp files in this directory are copies |
| of the .gyp files in the Chromium copy of NSS, with changes made to |
| account for the configurations and directory structure of the Dart |
| repository. Differences between the Chromium versions and the Dart |
| versions should be annotated with "# Added by Dart'. |
| |
| All the files should have a comment saying where the original file is |
| in the Chromium repository. To update these files, look at the diff |
| between the two revisions in Chromium, and apply the changes manually, |
| with any needed modifications, to the Dart copies. Our aim is to keep |
| the difference between the Chromium and Dart copies as small as |
| possible. |
| |
| The nss_memio.cc and nss_memio.h files are also taken from Chromium, |
| and should be updated at the same time. The os_Linux.s file is new, |
| and should not need changing. |
| |
| The file nss.gyp includes support for disabling compilation of NSS |
| using the variable dart_io_support, when building configurations that |
| don't use it. NSS compilation is disabled when building Dartium, |
| because Chromium includes its own copy, and the build process would |
| get confused. |
