PyCurl can significantly speed up client part if used properly (see DAS/DBS3). I need to add pycurl HTTP manager and use it for all remote calls, to do so I need to keep around single instance of curl object.

To do so I need to add numpy, matplotlib, zeromq, tornado packages in place.

I'm not sure if this is a bug or if I just don't know what I'm doing. I'm trying to change the dbs instance. I assume that I should be able to do :

dbs_instance cms_dbs_ph_analysis_01

but that gives me an invalid DBS instance message. Is this not working properly or am I doing something wrong. Implementing dbs_instance --help might be useful in the future.

Hi,
I get these warnings when I start cmssh:

/Users/nic/cms/soft/CMSSW/osx106_amd64_gcc421/external/py2-matplotlib/1.0.1-cms3/lib/python2.6/site-packages/matplotlib/__init__.py:397: UserWarning: matplotlibrc text.usetex option can not be used unless TeX-3.1415 or later is installed on your system

  'installed on your system') % gs_req)

This happens because I have my matplotlibrc set up to use latex. You might consider forcing the system to use a matplotlibrc that you have written rather than picking up the one in the home directory to prevent problems like this. I've written a matplotlibrc that looks somewhat like the official CMS plot style, if you'd like me to send it to you.

Right now I use root_init in setup.sh. Instead I need to wrap root call based on SCRAM_ARCH. Remove root_init from setup.sh, modify cms_root to do root_init call.

I can improve integration lumi calculation by adding intermediate step to check if run_lumi dict are within boundaries of golden JSON file. To do so I may extend cms_cmds::run_lumi_info function and check presence of this file
/afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions12/8TeV/Prompt/Cert_190456-202305_8TeV_PromptReco_Collisions12_JSON.txt

If so, I need to add helper function to load golden JSON from it and use it for comparison with found run lumi dict.

Hi,
I just (foolishly) tried to cp every file in a dataset to my computer in the background. Java ate all my memory and I had to reboot my computer. It would be nice if there was a queue of some sort, so that only 4 or so downloads are running at once.

Nic reported problem with cmssh, see https://gist.github.com/2503811

Warner example shows that user needs to type several times GRID pass phrase.

I'm trying to install cmssh on ubuntu and I'm running into a problem with the detection of the readline library.

[~] python cmssh_install.py --help
Traceback (most recent call last):
  File "cmssh_install.py", line 149, in <module>

I do, in fact have libreadline installed, but it's not finding it because it's in a different place. Here are the contents of the libreadline5 package in ubuntu.

If I can make a suggestion, a better way to check for libreadline might be

/sbin/ldconfig -p | grep libreadline

or the equivalent python command.

When I submit LFN transfer in background mode, it tries xrdcp method and fails sometimes since file cannot be transferred via xrdcp. So I need to fallback into lcg/srm mode somehow.

I'm having a problem copying by lfn. See the error message below. This file is in cms_dbs_ph_analysis_01, so maybe that has something to do with the problem. It looks fine if I prepend the site name to the lfn, i.e. T1_US_FNAL_Buffer:/store/user/...

I can hook-up git tool into cmssh and perform commits all user actions. Since git provides all versioning information and excellent logging capabilities it will means that whole history/provenance of user actions can easily captured. If user will be willing to setup git repository on github that it can be portable and distributable.

I need to modify installer to use existing CMSSW installation on given node. If VO_CMS_SW_DIR exists, I can create a link to this area, e.g. CMSSW -> $VO_CMS_SW_DIR. May be I'll need to create bunch of links, etc.

Sometime in the last few days, cmssh became very slow to respond to keypresses and also drops them if you type too quickly. I've tried reinstalling the newest dev version, rebooting my computer, and running it both in iTerm and Terminal.app. The only other oddity I've noticed is that I get an extraneous print asking for my grid password. Here's what it looks like:

Since I ship cmssh with pyROOT, I need to check how easy/hard will be analysis of ROOT files in cmssh. First step would be to check loading ROOT file content via PyROOT.

Once release is installed I need a new magic function to run cmsShow.

The versions of these libraries that are installed with CMSSW are somewhat old. Could the cmssh installer pull down the newest versions?

The output of dqueue when lots of jobs are in the queue is somewhat long and messy. Perhaps add a way to get just a summary of the number of jobs running, waiting, and finished.

I can think of two approaches for this.

1. Change the current dqueue command to print something like:

Waiting:
job1
job2
job3
job4
job5
...
+ 73 other jobs (use dqueue --full to see all jobs)

2. Leave dqueue as it is. Add a new command dqueue-summary or dqueue --summary which just prints the number of jobs in the in progress, waiting, and finshed states.

I'm often prompted to enter a PEM pass phrase when trying to copy a file from a storage element. Sometimes I'm asked for every file. This is quite annoying when I'm trying to copy every file in a dataset using a for loop.

I need to add:

• check if R exists in a path
• add installer part for rpy2
• change setup.sh to include path to R
• modify src/config/ipython_config.py and include rmagic extension

Eric suggested to try use xrdls in addition or as replacement of srm/lcg interfaces

I need to add a hook to add into magic functions a list of CMSSW utitilies, e.g. edmDump, etc. when user switch from one release to another. The hook should keep track of them, and discard old ones. Can be done via internal dict.

Apparently something wrong in the way we compile matplotlib that it cause crash when user try to save figure into PDF format, all other formats are fine

In multi-user environment, if system provides /cvmfs/cms.cern.ch, it's better to detect it and use it instead of /afs.

I can implement du SE:/path since it provides me enough information about given path. First I need to create an objects which will hold dir structure. So, it can be DirObject which has the following attributes, list of files with their file size and list of sub-dirs. Then it would be easy to implement sum/total function.

One user suggested that cmsh_install.py may incorrectly check presence of libreadline5 on a system. The /sbin/ldconfig -p may return a list where the first match may not be proper readline

Switch SCRAM_ARCH and install new/older releases. For example CMSSW_5_2 is using
export SCRAM_ARCH=slc5_amd64_gcc462, while CMSSW_5_0 based on gcc461 arch., etc.

It would be nice to have ability to kill transfer job

CMSSH matplotlib library does not ship with macosx driver. If I use the one I compile myself the plotting window is not showing, while graphics still can be save via savefig.

Hello,

I just installed on lxplus. Two pip packages were missing to make it work:
pytz
pycrypto

I just added then in line 825 of cmssh_install.py to the std_pkgs list.

cheers, Heiner
