bad workaround blockade of cms02 from belle7

On G:

svn up ~/env ; svn export --force ~/env ~/eenv
cd ; rsync -av eenv N:                ## deletes do not get propagated with this

On N:

export  ENV_HOME=/home/blyth/eenv ; ## modify in .bash_profile to use the exported

better workaround via reverse proxy on H

1. requies nginx to be running on H

2. one time svn switch –relocate is needed to keep working with the env WC on N:

   [blyth@belle7 e]$ svn switch --relocate http://dayabay.phys.ntu.edu.tw/repos/env http://hfag.phys.ntu.edu.tw:90/repos/env

3. ditto for heprez::

   [blyth@belle7 heprez]$ svn switch –relocate http://dayabay.phys.ntu.edu.tw/repos/heprez http://hfag.phys.ntu.edu.tw:90/repos/heprez

env functions

env-dbg

invoke with bash rather than . when debugging to see line numbers of errors, CAUTION error reporting can be a line off

env-rsync top-level-fold [target-node]

propagate a top-level-folder without svn, caution can leave SVN wc state awry ... usually easiest to delete working copy and “svn up” when want to come clean and go back to SVN

env-rsync-all [target-node]

rsync env working copy excluding .svn etc.. to a list of remote nodes specified by ssh node tag

env-again

delete working copy and checkout again

env-u

update the working copy, aliased to “eu”

env-rst name.bash

create rst wrapper to include the usage bash function

env-toc

create index.rst toctree referencing all .rst in PWD

absorbing an exported env working copy

Useful following server downtime:

[blyth@cms02 ~]$ diff -r --brief env env.keep | grep -v .svn | grep differ | perl -p -e 's,Files (\S*) and (\S*) differ,cp $2 $1, ' -

toctree hookup

When referring to implicit indices such as “python/python.bash” or “tools/tools.bash” use the form “python/index”. The bash2rst tool does the appropriate path swapping to generated a cleaner output tree without repeated levels.

Warning

this could be confusing when using manual index.rst together with auto generated _docs
