A simple python wrapper for C apis of quotactl
PyQuota is a simple python wrapper for C apis of quotactl.
Supported kernel versions:
Supported commands in C APIs:
Q_GETNEXTQUOTA(requires kernel >= 4.6)
Currently, none of the commands for XFS filesystem, e.g.
Q_XQUOTAON, are supported due to lack of documentations and testing environments.
pip install pyquota
For each of the supported commands, as listed above, this package provides 3 Python methods, which corresponds to operations on user quotas, group quotas and project quotas. Project quota methods requires kernel >=4.1.
For illustration purpose, only examples of user quota methods are provided here. To use group/project quota methods, you only need to replace 'user' in the method names with 'group' or 'project'.

Since this package is only a wrapper for the C APIs, it almost keeps the original flavor and input/output formats. Thus, if you want more details about the what each of these commands do, meaning of the arguments and meaning of the returned values, please read the man page.
Any internal error that comes from the C apis is translated to a
pyquota.APIError instance with a text description according to the ERRORS section in the man page.
