If there is a minor version bump in hdf5, any python code using pytables will fail with an error like: Warning! ***HDF5 library version mismatched error*** The HDF5 header files used to compile this application do not match the version used by the HDF5 library to which this application is linked. Data corruption or segmentation faults may occur if the application continues. This can happen when an application was compiled by one version of HDF5 but linked with a different version of static or shared HDF5 library. You should recompile the application or check your shared library related settings such as 'LD_LIBRARY_PATH'. You can, at your own risk, disable this warning by setting the environment variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'. Setting it to 2 or higher will suppress the warning messages totally. Headers are 1.8.8, library is 1.8.10 SUMMARY OF THE HDF5 CONFIGURATION ================================= General Information: ------------------- HDF5 Version: 1.8.10 Configured on: Mon Jan 14 11:10:24 MST 2013 Configured by: root@kelvin Configure mode: production Host system: x86_64-pc-linux-gnu Uname information: Linux kelvin 3.5.7-gentoo #1 SMP Tue Nov 20 14:51:34 MST 2012 x86_64 Intel(R) Core(TM) i7 CPU 980 @ 3.33GHz GenuineIntel GNU/Linux Byte sex: little-endian Libraries: Installation point: /usr Compiling Options: ------------------ Compilation Mode: production C Compiler: /usr/bin/x86_64-pc-linux-gnu-gcc CFLAGS: -march=native -O2 -pipe H5_CFLAGS: -std=c99 -pedantic -Wall -Wextra -Wundef -Wshadow -Wpointer-arith -Wbad-function-cast -Wcast-qual -Wcast-align -Wwrite-strings -Wconversion -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -Wnested-externs -Winline -Wno-long-long -Wfloat-equal -Wmissing-format-attribute -Wmissing-noreturn -Wpacked -Wdisabled-optimization -Wformat=2 -Wendif-labels -Wdeclaration-after-statement -Wold-style-definition -Winvalid-pch -Wvariadic-macros -Wnonnull -Winit-self -Wmissing-include-dirs -Wswitch-default -Wswitch-enum -Wunused-macros -Wunsafe-loop-optimizations -Wc++-compat -Wstrict-overflow -Wlogical-op -Wlarger-than=2048 -Wvla -Wsync-nand -Wframe-larger-than=16384 -Wpacked-bitfield-compat -Wstrict-aliasing -Wstrict-overflow=5 -Wjump-misses-init -Wunsuffixed-float-constants -O3 -fomit-frame-pointer -finline-functions AM_CFLAGS: CPPFLAGS: H5_CPPFLAGS: -D_POSIX_C_SOURCE=199506L -DNDEBUG -UH5_DEBUG_API AM_CPPFLAGS: -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_BSD_SOURCE -D_GNU_SOURCE Shared C Library: yes Static C Library: no Statically Linked Executables: no LDFLAGS: -Wl,-O1 -Wl,--as-needed H5_LDFLAGS: AM_LDFLAGS: Extra libraries: -lz -lrt -lm Archiver: x86_64-pc-linux-gnu-ar Ranlib: x86_64-pc-linux-gnu-ranlib Debugged Packages: API Tracing: no Languages: ---------- Fortran: yes Fortran Compiler: /usr/bin/x86_64-pc-linux-gnu-gfortran Fortran 2003 Compiler: no Fortran Flags: -O2 -pipe H5 Fortran Flags: AM Fortran Flags: -O2 -pipe Shared Fortran Library: yes Static Fortran Library: no C++: yes C++ Compiler: /usr/bin/x86_64-pc-linux-gnu-g++ C++ Flags: -march=native -O2 -pipe H5 C++ Flags: AM C++ Flags: Shared C++ Library: yes Static C++ Library: no Features: --------- Parallel HDF5: no High Level library: yes Threadsafety: no Default API Mapping: v18 With Deprecated Public Symbols: yes I/O filters (external): deflate(zlib) I/O filters (internal): shuffle,fletcher32,nbit,scaleoffset MPE: no Direct VFD: yes dmalloc: no Clear file buffers before write: yes Using memory checker: no Function Stack Tracing: no GPFS: no Strict File Format Checks: no Optimization Instrumentation: no Large File Support (LFS): yes Bye... zsh: abort Neither python-updater nor revdep-rebuild catch this, so it's very annoying since it time and time again breaks my long running scripts.

Consider introducing slots in sci-libs/hdf5 such that dev-python/pytables gets recompiled each time the sci-libs/hdf5 slot changes, you can do this by depending on "sci-libs/hdf5:="; unless there is a better alternative available, as slotting might not be feasible if only a single package is affected.

This affects almost every package using hdf5. I requested the same thing in bug 445268, so this might be considered a duplicate. I'd prefer a better solution to what got done in that bug, though.
*** Bug 452672 has been marked as a duplicate of this bug. ***
Generally speaking I think the message and the abort by default is strange: Either the ABI did change, and they should've changed SONAME, or there wasn't an ABI change and then compatability should be ensured. I found the following thread on their ML: http://hdf-forum.184993.n3.nabble.com/Results-of-backward-binary-compatibility-tests-for-libhdf5-td2774626.html So here we can see: - there was a case where the warning and abort was useful, - they attempt to maintain compatability In the end I'd vote for using subslots, since personally I'd rather rebuild all libraries that depend on hdf5 rather than silence that warning.
http://upstream-tracker.org/versions/hdf5.html shows no api changes since 1.8.7
Created attachment 340252 [details, diff] patch to hdf5 ebuild First part of my proposed patch set. This one bumps hdf5 to EAPI5, adds a subslot, and removes the warning message. Patch for pytables ebuild coming up.
Created attachment 340254 [details, diff] patch to pytables ebuild Second part of my proposed patch set. This one bumps pytables to EAPI5 and adds a slot := dependency on hdf5.
Thanks for the patch! I vote in favor of this solution.
