| 45 | Tahoe will download and install most of the libraries it requires when you |
| 46 | run "{{{make}}}". You might want to pre-download these libraries: perhaps you |
| 47 | are about to get on an airplane, or you anticipate having poor network |
| 48 | connectivity, or you just don't like the idea of a so-called compile step |
| 49 | using the network (the download step uses !PyPI to figure out where to |
| 50 | download these libraries from, so you might be concerned that it or one of |
| 51 | the project web pages it references has been modified to point at something |
| 52 | malicious). |
| 53 | |
| 54 | This disconnected-build operation is supported in two ways. When building |
| 55 | from a darcs checkout, you can download the latest "tahoe-deps" bundle from |
| 56 | http://allmydata.org/source/tahoe/deps/tahoe-deps.tar.gz . Unpack this in |
| 57 | your source tree, and the build process will grab any necessary libraries |
| 58 | from its {{{tahoe-deps/}}} directory instead of downloading them from the |
| 59 | internet. You can also unpack tahoe-deps into the parent directory to share |
| 60 | it between multiple trees. |
| 61 | |
| 62 | Alternatively, if you are building from a tarball (either a release tarball |
| 63 | from http://allmydata.org/source/tahoe/releases/ , or a continually-generated |
| 64 | current-trunk tarball from http://allmydata.org/source/tahoe/tarballs/ ), you |
| 65 | can simply download the -SUMO version of the tarball instead of the regular |
| 66 | one. The "SUMO" tarball includes the current tahoe-deps bundle pre-unpacked |
| 67 | in the source tree. |
| 68 | |
| 69 | The tahoe-deps bundle is updated every once in a while, as new versions of |
| 70 | the dependent libraries are released, or as Tahoe becomes dependent upon new |
| 71 | things. The http://allmydata.org/source/tahoe/deps/ directory contains |
| 72 | historical ones, but there should never be a reason to use anything but the |
| 73 | latest. The tahoe-deps bundle contains a README that has a version number. |
