[svn-r136] ./MANIFEST
./src/Makefile.in Added H5Ffamily.c and H5Fsplit.c ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c Added `const' to sublass arguments. ./src/H5F.c ./src/H5Flow.c ./src/H5Fsec2.c Make sure file buffers get flushed during a call to H5Fflush(). Check for overflow in address encoding and decoding. ./src/H5Ffam.c ./src/H5Fprivate.c ./test/istore.c Implementation of file families so 32-bit machines can access 64-bit files. ./src/H5Oprivate.h Removed H5O_NO_ADDR constant. ./config/freebsd2.2.1 ./config/linux Added -DH5G_DEBUG and -DH5F_DEBUG to the list of debugging flags. ./html/H5.format.html Changed some <offset>-sized things to <length>-sized things. ./src/H5AC.c ./src/H5ACprivate.h ./src/H5B.c ./src/H5Bprivate.h ./src/H5C.c ./src/H5D.c ./src/H5F.c ./src/H5Fcore.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c ./src/H5Fstdio.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gshad.c ./src/H5Gstab.c ./src/H5H.c ./src/H5Hprivate.h ./src/H5MF.c ./src/H5MFprivate.h ./src/H5O.c ./src/H5Ocont.c ./src/H5Oistore.c ./src/H5Oprivate.h ./src/H5Ostab.c ./src/H5Ostdst.c ./src/H5pivate.h ./src/debug.c ./test/istore.c ./test/theap.c ./test/tohdr.c ./test/tstab.c Lots of changes caused by generalizing addresses. The haddr_t is now a struct, so you can no longer perform arithmetic on it. But since it's small, simple, and often used, storage is allocated like with an integer. But we always pass them around by reference. That is, when using an address in another struct, allocate space: struct my_struct { char *name; haddr_t address; } x; But when passing it to a function, pass by reference: H5F_addr_print (stderr, &(x.address)); Addresses should be initialized with H5F_addr_undef (&(x.address)); Functions for operating on addresses are in H5Flow.c and begin with H5F_addr_... Functions never return haddr_t or haddr_t*; they always pass them through arguments instead. A function that returns an address through an argument does so with its last argument and it is marked with `/*out*/'. Calls to such functions also mark output-only arguments with `/*out*/' ./src/H5Fsplit.c (new) A two-member family where all meta data goes in the first member and all raw data goes in the second member. ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5Ffamily.c ./src/H5Fistore.c ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsec2.c ./src/H5Fstdio.c ./src/H5Gnode.c ./src/H5H.c ./src/H5MF.c ./src/H5MFprivate.h ./src/H5O.c Differentiate between meta data storage and raw data storage. Provide a mechanism so that the file driver can extend the file to allocate more memory. ./src/H5E.c ./src/H5Epublic.c Added the error H5E_TRUNCATED to be reported when the file is shorter than the length recorded in the boot block. ./src/H5F.c Added H5F_locate_signature() so we only do it in one place now. ./INSTALL ./INSTALL_MAINT Just a couple clarifications. ./html/ExternalFiles.html ./html/storage.html Documents how external files work. ./test/hyperslab.c ./test/istore.c Fixed printf's on 64-bit machines. ./test/istore.c Added ifdef's to test the split file driver.
