Re: Checking out src with Mercurial

Hi,

some closing words from someone whose arguments in the previous thread were more for Git...

I have tried several times during the week to clone the NetBSD repository using Mercurial. I had observed a high CPU load and an apparently unfinished checkout. I tried again and now the experiences have shifted somewhat positively.

First a tip for everyone who has an unstable internet connection: The effects appear more clearly with Mercurial, because in the current constellation (internet bandwidth, speed of the anonhg server?, ....) it takes a few operations longer than Git and this increases the likelihood of becoming a victim of network fluctuations during an operation. My observation is that sometimes an error message (timeout) occurs and the transaction is rolled back. In this case, everything called up to that point is invalid and you have to start over. Depending on the phase, the process does not seem to notice this when a network fluctuation occurs and instead is stuck in a state in which 100% CPU is used without noticeable progress. That was obviously also the cause of my original experience, in which the cloning of src did not come to an end even after 11 hours on a relatively modern i5 PC.

[...]

Considering that a cvs update on my VAX takes roughly 24 hours, I do not look forward to trying hg or git... :-)

Anyone who dares take a bet on how long it will take, assuming things don't just timeout and die in the meantime?

(It's a 4000/90 with 128M of ram, so nothing extremely slow, I doubt I'll ever try on the 8650 with 60M of ram and RA73 disks...)
