Please keep me updated on the timing of this. Despite the recent string of releases, I actually expect the amount of time I'll have to work on Botan will reduce pretty dramatically for a while in the neat future. So if Botan 1.7.x is going to distros (AFAIK the only distro it is currently in is Debian) I would just as soon it be the future 1.7.15 rather than .14 since there are another slew of changes (in particular adding ECDSA). I don't have an ETA in particular planned for the release (sometime this month, probably); if you need a fresh 1.7 release to accompany a new version of Monotone at a particular time just let me know. -Jack ___ Monotone-devel mailing list Monotone-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/monotone-devel

I've been rattling emails off of Jack trying to get both the sha1_ia32 and sha1_sse2 modules to properly configure on my pentium-m and I think that's now working so I'll see how they perform here. Initial tests with botan seem to show that ia32 asm is faster than sse2 on pentium-m which seemed a bit odd. After just having upgraded (and now landed) monotone's included botan to > 1.7.12.

I noticed that gentoo only has 1.6.5 or something so I'll see if I can encourage someone in portage land to get the botan dev stuff in as unstable.

I've started such an effort in nvm.stripped. Beginning with: * botan (because I know that from earlier upgrades) * pcre (because it was so easy) * lua (becasue I'm been afraid of the problems you mentioned) The m4 scripts for botan and lua are stolen from the library-build build branch and adjusted. I'm not an m4 hacker, so if some m4 guru could check those that'd be great. The branch builds on my debian lenny against botan 1.7.8 (up to head), pcre 7.6 and lua 5.1 as external libraries. It passes all tests of the testsuite and weights 30 MiB (vs 37 MiB on mainline and Intel 32bit). > It also became clear that there are still quite a few hacks that we > rely on in our local copies of the libraries.

After just having upgraded (and now landed) monotone's included botan to 1.7.12. Jack is already approaching 1.7.15 with yet another set of renaming. I'm rather going to use the nvm.stripped branch than continue to manually upgrade again.
