It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

[svn-r1087] Changes since 19990218 ---------------------- ./src/H5F.c ./src/H5private.h ./src/H5Ipublic.h ./src/H5O.c Fixed a rather nasty bug with file closing that caused the file boot block to be updated incorrectly, effectively truncating the file. The bug I fixed was triggered by: 1. Create a file, F 2. Open an object, X 3. Close file F 4. Reopen file F for read/write. 5. Create and close some objects 6. Close file F 7. Close library (exit). Step 3 pended the close because object X is still open, but the file ID was removed from the H5I_FILE ID group. Step 4 created a new file because it didn't see any matching file on the H5I_FILE ID group. Step 5 extends the file. Step 6 writes the new file boot block to disk. Step 7 closes object X and completes the close from step 3, writing the old boot block information to disk. The new behavior is that step 3 moves the file from the H5I_FILE group to the H5I_FILE_CLOSING group. Step 4 searches both groups and finds the file. Step 5 extends the file using the same H5F_file_t struct as step 3. Step 6 closes the H5F_t struct opened in step 3 but not the H5F_file_t struct shared by steps 1 and 3. Step 7 closes object X which closes the H5F_file_t from step 1, flushing the boot block which was shared by all steps. ./src/H5F.c Added some bulletproofing to file reference counting and removed comments which no longer apply. Added H5F_flush_all() and H5F_close_all() which apply to all files. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5Iprivate.h ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c Added the new H5I_free_t data type to describe the function type to be passed as the `free_func' argument to H5I_init_group(). ./src/H5I.c Bulletproofed the object removal functions. Removed comments which no longer apply. Changed global variable names so they don't violate the naming scheme. Added H5I_debug() that prints the contents of an ID group. Removed H5I_inc_ref() because it isn't used. Reindented a couple of functions. ./src/H5.c ./src/H5G.c ./src/H5Ipublic.h Changed H5I_MAXID to H5I_NGROUPS to better relect the fact that it's the total number of valid ID groups. ./src/H5Shyper.c Changed hyperslab offset arrays to signed quantities to get rid of warnings on DEC cluster. ./src/H5Flow.c ./src/H5Fprivate.h Changed the objno argument of H5F_addr_pack() to be unsigned to get rid of warnings on DEC cluster.

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)
