1461390 - With mercurial 4.6, repeated error spam: "*** failed to import extension bundleclone from [wherever]: No module named wireproto"

Status: RESOLVED WONTFIX

(Developer Services :: Mercurial: bundleclone, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Have bundleclone configured normally -- in particualr, listed in the [extensions] section of your ~/.hgrc file.  For me, the line looks like this:
> [extensions]
> bundleclone = /scratch/work/builds/.mozbuild/version-control-tools/hgext/bundleclone


2. Install/upgrade Mercurial 4.6, e.g. via pip on Ubuntu:
>    pip install --user -U mercurial
 (and run "hg --version" to be sure you're really running version 4.6)


3. Run any hg command, e.g. "hg status", anywhere on your system.

ACTUAL RESULTS:
*** failed to import extension bundleclone from /scratch/work/builds/.mozbuild/version-control-tools/hgext/bundleclone: No module named wireproto


EXPECTED RESULTS:
No such error.

I think this is new in Mercurial 4.6 -- maybe this wireproto thing was renamed or moved between namespaces or something? https://www.mercurial-scm.org/wiki/Release4.6 does mention some stuff about wireproto.

If I enable traceback, I get this additional diagnostic output:

[Gregory Szorc [:gps]]

The bundleclone extension was deleted ~1 year ago (bug 1352494). The functionality is now baked into Mercurial itself.

Your Mercurial is likely picking up a cached version in a .pyc file in your version-control-tools checkout. (Oh, Python.)

Please remove references to the bundleclone extension from your hgrc files.

Indeed, it looks like /scratch/work/builds/.mozbuild/version-control-tools/hgext/bundleclone/__init__.pyc was the only bundleclone-related file in my version-control-tools checkout.

Thanks!
