Notes: |
2 |
- Total conversion time on the order of 20 hours of wallclock. |
3 |
- cvs2svn seems to be entirely single-threaded :-(. |
4 |
- Dropped: chriswhite's vendorbranch |
5 |
- Dropped: branches: 'RELEASE-1_4', 'MAIN' |
6 |
- Dropped: tags: 'GENTOO_1_4_SNAP_2003010800', 'gentoo_1_0_rc5', 'gentoo_1_0_rc1' |
7 |
- DID run with Linus's memory improvements. Helped :-). |

TODO: |
10 |
- Could somebody with Python-foo please look hard at cvs2svn with an eye to |
11 |
making it multi-threaded? |
12 |
- Focus on pass1 and pass9. |
13 |
- pass8 maybe as well, but I think it will be harder by design. |
14 |
- We need incremental conversion stuff badly. |
15 |
- I had to use the RCSRevisionReader, as InternalRevisionReader seemed to be |
16 |
broken. Would make pass1 faster as well. |
17 |
- Should probably ignore the '.frozen' files. |
18 |
- Review RCS state of ALL ,v files. There are a few non-dead files in Attic. |
19 |
- Maybe trim out the Manifest/digest contents during the conversion, leaving |
20 |
only DIST lines? |
21 |
Con: _WOULD_ break old GPG signatures. |
22 |
Pro: probably help size a lot. |
