Priority: normal
Bug ID: 4659
CC: mercurial-devel at selenic.com
Assignee: bugzilla at selenic.com
Summary: Pulling the Netbeans repo requires hundreds of
roundtrips during discovery
Severity: bug
Classification: Unclassified
OS: All
Reporter: gregory.szorc at gmail.com
Hardware: All
Status: UNCONFIRMED
Version: 3.4
Component: Mercurial
Product: Mercurial
I have a clone of the http://hg.netbeans.org/main sitting around. I like using
it for performance analysis as an alternative to mozilla-central.
I pulled it with @ a few minutes ago and to my surprise discovery takes almost
600 round trips!
STR:
1. hg clone http://hg.netbeans.org/main
2. hg strip -r 791c0ff85f77: (to simulate the state of my old clone)
3. hg pull
If I strip just a few tip-most changesets, the problem isn't as severe.
Several of the requests appeared to be "branches" lookups. I didn't dig too
much into details.
I'm kinda surprised nobody from Netbeans has complained about this: this is
quite possibly the worst `hg pull` experience I've ever seen.
