Re: [Pytables-users] a question about data corruption.
Hello Gelin, Unless you were using the undo / redo mechanism, then I don't think that there is. You'll probably have to fix the file manually using PyTables normally and the provided tools like ptrepack.

[Pytables-users] a question about data corruption.
Hi All I have a question about data corruption. Is it possible to repair data file when there is a situation like power outage or process crash? I have poked around the manual; however I did fail to find anything about how to repair corrupted data if it happened. Thanks Regards gelin yan -- Everyone hates slow websites. So do we.

[Pytables-users] [ANN] Blosc 1.1.4 released
=== Announcing Blosc 1.1.4 A blocking, shuffling and lossless compression library === What is new? - Redefinition of the BLOSC_MAX_BUFFERSIZE constant as (INT_MAX - BLOSC_MAX_OVERHEAD) instead of just INT_MAX. This prevents to produce outputs larger than INT_MAX, which is not supported. - `exit()` call has been replaced by a ``return -1`` in blosc_compress() when checking for buffer sizes. Now programs will not just exit when the buffer is too large, but return a negative code. - Improvements in explicit casts. Blosc compiles without warnings (with GCC) now. - Lots of improvements in docs, in particular a nice ascii-art diagram of the Blosc format (Valentin Haenel). - [HDF5 filter] Adapted HDF5 filter to use HDF5 1.8 by default (Antonio Valentino). For more info, please see the release notes in: https://github.com/FrancescAlted/blosc/wiki/Release-notes What is it? === Blosc (http://blosc.pytables.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc is the first compressor (that I'm aware of) that is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate object manipulations that are memory-bound. It also comes with a filter for HDF5 (http://www.hdfgroup.org/HDF5) so that you can easily implement support for Blosc in your favourite HDF5 tool. Download sources Please go to main web site: http://blosc.pytables.org/sources/ or the github repository: https://github.com/FrancescAlted/blosc and download the most recent release from there. Blosc is distributed using the MIT license, see LICENSES/BLOSC.txt for details.
