| | | | | | | | limits to be placed on how much memory is used by the free lists before they are garbage collected. The default is to have no limit, with garbage collection only occurring when they cannot allocate memory.

* [svn-r2348] The way the pthread_t object was being initialized wasn't ↵Bill Wendling2000-06-062-13/+26
| | | | | | | | | | | | correct for all platforms. Also, it's not entirely certain that a value of 0 isn't a valid thread ID. So, I changed the pthread_t object to be a pointer to pthread_t with the appropriate memory management this entails. Part of the validity of this approach rests on the fact that one can assign a variable which is a structure to another variable of the same type and all fields within will be copied appropriately...See! C *does* do some things correctly :-).

| | | | | | | | objects being cached instead of in separate structures. This reduces the amount of memory the hash table uses by about half. This is the initial step along the path of speeding up the metadata caching.

* [svn-r2286] Gave the threading functions return types (herr_t). pthreads' callsBill Wendling2000-05-192-94/+163
| | | | | | | | | | | | | return 0 on success and non-zero on failure. That's what happens with these calls. There was a problem compiling threading on Linux. The pthread_t type is not consistent among different implementations, so it cannot simply be assigned to NULL or tested against it. I initialize it by calling HDmemset(foo_thread, 0, sizeof(pthread_t)). To see if it's a "null" pthread, I created a special pthread_t object (assigned to only in the init phase and then only read...i.e., thread safe) and assigned it "null" as above. Then I use pthread_equal() to determine if the thread is null.

* [svn-r2264] Added Thread-safe feature. This is the phase 1 implementationChee-Wai Lee2000-05-186-23/+459

* [svn-r2262] * 2000-05-18Robb Matzke2000-05-1813-498/+870
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ** src/H5Tconv.c ** src/H5Tpkg.h ** src/H5Tpublic.h The H5T_conv_struct_opt() function had a design flaw -- it didn't keep information about the stride to use to step through the temporary/background-value buffer and thus nested invocations would clobber each other's temp buffers. This was fixed by splitting the `stride' argument into `buf_stride' and `bkg_stride' arguments for all the conversion functions. THIS IS AN API CHANGE, but users will get a compiler warning when they pass their conversion function pointer to H5Tregister(). ** src/H5T.c ** src/H5Tprivate.h Added a bkg_stride argument to the H5T_convert() definition in order to fix a bug related to the optimized compound datatype conversion function. ** src/H5T.c ** src/H5A.c ** src/H5D.c ** src/H5Ofill.c ** src/H5P.c Added bkg_stride=0 argument to the H5T_convert() calls. ** test/dtypes.c Added a test for the H5T_conv_struct_opt() bug fixed above. ** src/H5FL.c The H5FL_term() function should return non-zero even when it couldn't free all the free lists do to their being used by some other package. When that other package terminates it will return non-zero, causing H5FL_term() to be called again. This fixes some of the `infinite loop closing library' messages. ** tools/pdb2hdf Uses print_version() instead of doing that itself. ** src/H5Ppublic.h Renamed H5Pget_gc_reference() declaration to make it match the definition. ** src/H5FDlog.c Added API tracing macros. Removed `const' qualifier from a `char*' member of a struct which was allocated on the heap. ** src/H5TB.c Added curly braces to a couple deeply-nested `if' statements to make them clearer and to shut up the increadibly stupid and just plain incorrect gcc warning about ambiguous `else'. ** test/titerate.c Removed incomplete initialization in favor of memset() for one auto variable to stop compiler warnings. ** tools/Depencencies Regenerated to remove references to h5dumputil.c
