This exception is raised the low level PyTables components used for accessing HDF5 files. It usually signals that something is not going well in the HDF5 library or even at the Input/Output level. Errors in the HDF5 C library may be accompanied by an extensive HDF5 back trace on standard error (see also :func:`tables.silence_hdf5_messages`). .. versionchanged:: 2.4 Parameters ---------- message error message h5bt This parameter (keyword only) controls the HDF5 back trace handling. Any keyword arguments other than h5bt is ignored. * if set to False the HDF5 back trace is ignored and the :attr:`HDF5ExtError.h5backtrace` attribute is set to None * if set to True the back trace is retrieved from the HDF5 library and stored in the :attr:`HDF5ExtError.h5backtrace` attribute as a list of tuples * if set to "VERBOSE" (default) the HDF5 back trace is stored in the :attr:`HDF5ExtError.h5backtrace` attribute and also included in the string representation of the exception * if not set (or set to None) the default policy is used (see :attr:`HDF5ExtError.DEFAULT_H5_BACKTRACE_POLICY`) NÚVERBOSEcCsbdddddddœ}|j}tj dd¡}z|| ¡}Wn tyVt d|¡Yn0||_|S)NFTr)ZIGNOREZFALSEZSAVEZTRUErÚDEFAULTZPT_DEFAULT_H5_BACKTRACE_POLICYrz™Invalid value for the environment variable 'PT_DEFAULT_H5_BACKTRACE_POLICY'.

For instance, listing the children of a closed group is not allowed. N©r)r*r+r,rrrrr/Çsr/c@seZdZdZdS)ÚClosedFileErrorzŸThe operation can not be completed because the hosting file is closed. For instance, getting an existing node from a closed file is not allowed. Nr0rrrrr1Ñsr1c@seZdZdZdS)Ú FileModeErrorzËThe operation can not be carried out because the mode in which the hosting file is opened is not adequate. For instance, removing an existing leaf from a read-only file is not allowed. Nr0rrrrr2Üsr2c@seZdZdZdS)Ú NodeErroraÈInvalid hierarchy manipulation operation requested. This exception is raised when the user requests an operation on the hierarchy which can not be run because of the current layout of the tree. This includes accessing nonexistent nodes, moving or copying or creating over an existing node, non-recursively removing groups with children, and other similarly invalid operations. A node in a PyTables database cannot be simply overwritten by replacing it. Instead, the old node must be removed explicitely before another one can take its place. This is done to protect interactive users from inadvertedly deleting whole trees of data by a single erroneous command. Nr0rrrrr3èsr3c@seZdZdZdS)ÚNoSuchNodeErrorz¿An operation was requested on a node that does not exist. This exception is raised when an operation gets a path name or a ``(where, name)`` pair leading to a nonexistent node. Nr0rrrrr4üsr4c@seZdZdZdS)Ú UndoRedoErrorzúProblems with doing/redoing actions with Undo/Redo feature. This exception indicates a problem related to the Undo/Redo mechanism, such as trying to undo or redo actions with this mechanism disabled, or going to a nonexistent mark. Nr0rrrrr5sr5c@seZdZdZdS)ÚUndoRedoWarningz…Issued when an action not supporting Undo/Redo is run. This warning is only shown when the Undo/Redo mechanism is enabled. Nr0rrrrr6sr6c@seZdZdZdS)ÚNaturalNameWarningaIssued when a non-pythonic name is given for a node. This is not an error and may even be very useful in certain contexts, but one should be aware that such nodes cannot be accessed using natural naming (instead, ``getattr()`` must be used explicitly). Nr0rrrrr7sr7c@seZdZdZdS)ÚPerformanceWarningzîWarning for operations which may cause a performance drop. This warning is issued when an operation is made on the database which may cause it to slow down on future operations (i.e. making the node tree grow too much). Nr0rrrrr8)sr8c@seZdZdZdS)Ú FlavorErrorzûUnsupported or unavailable flavor or flavor conversion. This exception is raised when an unsupported or unavailable flavor is given to a dataset, or when a conversion of data between two given flavors is not supported nor available. Nr0rrrrr95sr9c@seZdZdZdS)Ú FlavorWarninga`Unsupported or unavailable flavor conversion. This warning is issued when a conversion of data between two given flavors is not supported nor available, and raising an error would render the data inaccessible (e.g. on a dataset of an unavailable flavor in a read-only file). See the `FlavorError` class for more information. Nr0rrrrr:As r:c@seZdZdZdS)ÚFiltersWarningzËUnavailable filters. This warning is issued when a valid filter is specified but it is not available in the system. It may mean that an available default filter is to be used instead. Nr0rrrrr;Psr;c@seZdZdZdS)ÚOldIndexWarningz¾Unsupported index format. This warning is issued when an index in an unsupported format is found. The index will be marked as invalid and will behave as if doesn't exist. Nr0rrrrr<\sr<c@seZdZdZdS)ÚDataTypeWarningz¤Unsupported data type. This warning is issued when an unsupported HDF5 data type is found (normally in a file created with other tool than PyTables). Nr0rrrrr=hsr=c@seZdZdZdS)ÚExperimentalFeatureWarningz¬Generic warning for experimental features. This warning is issued when using a functionality that is still experimental and that users have to use with care.
