Note that the changes to add_statmap
are so that this is checked in the CI - codes should change to use HFile rather than h5py.File gradually, but I won't change them all in one go
Is there any more information on the motivation for this PR? I'm not sure how I feel about linking version of the pycbc library information into a file like this.
@ahnitz sorry, I should have added you as a reviewer to get your opinion as well, as it is a proposal at the moment
Basically as different pycbc versions may not be able to work together, I thought it best to warn about this rather than anyone expecting the codes to work across different versions.
This would additionally help with code review as the reviewer could check that the pycbc version in the result files matches the one which should have been run
Note that the general option of pycbc always using HFile as a wrapper would go someway towards solving #1525
Add a
pycbc_version
attribute when opening a HFile to write, and check that it exists/matches when opening for reading.Standard information about the request
This is a new feature This change (can) affect all codes which use h5py input/output, if wanted This changes warnings seen when running the code, no scientific content or results plotting will be affected
This change follows style guidelines (See e.g. PEP8), has been proposed using the contribution guidelines
I can add unit tests if desired
This change will warn when different versions of PyCBC are being used
Motivation
When the code changes, there are (sometimes unwitting) differences in how the files from the code are output/input. This just adds a warning to the user to be wary of that.
Contents
When a HFile object is opened, the file read/write permission will be used to determine whether or not to check / update the
pycbc_version
attribute.Testing performed
Tested each case (same / different versions, and unversioned files), and the correct warnings are given each time. Tested that the permissions are carried through to the underlying h5py.File, and appropriate errors are raised.
