Submodules

qharv.trans.move module

qharv.trans.move.inverse_st_map(flist, new_dir, old_dir)[source]

fix common screw up: moved all source files without saving st_map

e.g.
inverse_st_map([‘./opt_backup/opt0’, ‘./opt_backup/opt1’],

‘./opt_backup’, ‘./run’)

Parameters

  • flist (list) – a list of backedup file locations

  • new_dir (str) – directory holding the backups

  • old_dir (str) – directory to restore backups to

qharv.trans.move.move_by_st_map(st_map)[source]

move files according to source-target map

Parameters

st_map (dict) – source-target map

qharv.trans.move.source_target_map(flist, new_dir)[source]

for each file in flist, provide its new location in new_dir

e.g.

source_target_map([‘./run/opt0’, ‘./run/opt1’], ‘./opt_backup’)

Parameters

  • flist (list) – a list of file locations

  • new_dir (str) – location of new directory

Returns

st_map, source-target map for files operations such as copy or move.

Return type

dict

qharv.trans.nexus_qmc module

qharv.trans.nexus_qmc.backup(ref_loc, tar_loc, execute=False, skip_exist=False, overwrite_target=False, verbose=True)[source]

essentially rsync from bash, but with a bunch of checks

qharv.trans.nexus_qmc.backup_calculations(ref_dir, tar_dir, subdirs, execute=False, verbose=True, **bk_kws)[source]

copy all nexus calculations listed in subdirs from ref_dir to tar_dir motivation: backup nexus-generated calculations and rerun with a tweak problem: nexus keeps a run folder and a result folder in parallel. A full backup

must take both folders into account and keep them consistent.

Parameters

  • ref_dir (str) – reference directory containing calculations to backup tar_dir (str): target directory to backup (e.g. attic/)

  • subdirs (list) – a list of folders names generated by nexus, e.g. [‘opt’,’dmc’]

  • bk_kws (dict) – keyword arguments to pass to backup(ref_loc,tar_loc)

Returns

a list of source-target maps backed up, this list can be used

to clean the backed up directory

Return type

list

qharv.trans.nexus_qmc.find_run_folders(results_dir)[source]

find all nexus-generated run folders given the results folder
