* Brings the thread-safety recursive writer locks to 1.12 (#466)Dana Robinson2021-05-141-55/+507
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * First cut at replaceing the existing mutex with a recursive R/W lock. This implementation has the following issues: 1) pthreads implementation only -- we still need a windows version. 2) must investigate thread cancelation issues 3) Error reporting is very poor. I followed the error reporting on the existing thread safe code, but this should be re-visited and improved. Code is currently setup to use the new recursive R/W lock instead of the global mutex to control entry to the library in threadsafe builds. To revert to the global mutex, set H5TS__USE_REC_RW_LOCK_FOR_GLOBAL_MUTEX in H5TSprivate.h to FALSE. Added a reasonably robust regression test for the reursive R/W lock in test/ttsafe_rec_rw_lock.c Note that the change to hl/src/H5LTanalyse.c is an artifact of clang-format. Tested serial threadsafe debug and production on jelly, and also regular serial / debug. On Windows builds, the new recursive R/W lock should not be built and we should use the existing global mutex -- however this is not tested at this time. * Updates CMake to build recursive RW lock test * Updates to allow building on Windows * Moves #if statements to better protect non-RW lock code * Adds configure and CMake options for the recursive RW locks * Committing clang-format changes * Updates RELEASE.txt and the build options * Renames H5TS RW lock things * Makes struct members platform independent Also removes _ptr from identifiers * Partial thread-safety RW locks platform independence * Committing clang-format changes * Pthreads side of things is platform-independent now * Formatted source * Added Windows equivalents for some Pthreads calls * Rename H5TS takedown call to destroy * Reorg of RW lock code * Committing clang-format changes * Changes to Pthreads code after development on Visual Studio * Moves stats macros to static inline functions and tidies memory allocs * Converts RW lock print stats call to use C99 formatting * Fixes typos * Formatted source * Updates the RELEASE.txt note to indicate no Win32 threads support Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

* [svn-r24961] Updates to Win32 thread-local storage cleanup when the ↵Dana Robinson2014-04-041-4/+9
| | | | | | | | | | | thread-safe library is built on Windows. Previously, thread-local storage was not cleaned up, causing resource leaks. Fixes HDFFV-8518, HDFFV-8699 As a part of these changes, the thread-safe + static library options are declared unsupported since the solution relies on DllMain. A solution for the static library is probably doable, but requires much more complicated surgery and has been deferred to HDF5 1.8.14. Tested on: 64-bit Windows 7 using VS 2012 (changes only affect Windows)
* [svn-r19384] Description:Quincey Koziol2010-09-151-1/+1
| | | | | | | | | | Correct an error I convinced Mike to introduce with the phread_once() code, :-( along with another one that wasn't my fault. Also, clean up warnings and restructure code in the thread-safe code a bit. Tested on: Mac OS X/32 10.6.4 (amazon) w/production + thread-safe (not a configuration that h5committest tests)
* [svn-r19367] Purpose:Mike McGreevy2010-09-101-5/+66
| | | | | | | | | | | | | | | | | | | Add windows threads support to HDF5. Description: Added calls to the windows threads library to the H5TS layer, and wrapped most calls to either pthreads or windows threads library with portable H5TS-style defines. Modified tests to use portable function definitions as well. This can be configured via CMake with the HDF5_ENABLE_THREADSAFE option, and should work on windows vista and later operating systems. Tested: h5committest, plus threadsafe with pthreads on jam and amani, and tested on a Windows Vista VM with threadsafe using windows threads.
* [svn-r14419] Description:Quincey Koziol2008-01-151-1/+0

* [svn-r11733] Purpose:Quincey Koziol2005-11-161-1/+2
| | | | | | | | | | | | | | | | | | Code cleanup Description: Added some comments about the thread-specific memory for the error and function stacks. Changed H5close() to not use the function stack (since it causes it to be re-enabled after shutting it down) Changed thread-safe semaphore code to not use dynamicly allocated memory. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Too minor to require h5committest

* [svn-r6383] Purpose:Quincey Koziol2003-02-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature for developers. Description: Added "function stack" tracing to library. This allows developers (there is no public API) to call H5FS_print within the library and get a listing of the functions traversed to reach that point in the library. Eventually, I may add support for reporting the parameters to each function also... Mainly for debugging parallel I/O programs, but I think it will come in handy in other cases also. The function stack tracking is controlled with a configure switch: --enable-funcstack, which defaults to enabled currently. When we branch for 1.6, we should change the default setting on the branch to be disabled. Also, added a destructor to the thread-specific keys when thread-safety is turned on in the library. Otherwise, they were leaking memory and causing difficult to debug errors in threaded programs (like the test/ttsafe test). Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) w/thread-safety enabled. Misc. update: Updated MANIFEST with new files added (src/H5FS.c & src/H5FDprivate.h) Update release_docs/RELEASE with thread-safety bug fix.

| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r3781] Purpose:Bill Wendling2001-04-051-3/+3
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r2348] The way the pthread_t object was being initialized wasn't ↵Bill Wendling2000-06-061-1/+1
| | | | | | | | | | | | 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 :-).
* [svn-r2286] Gave the threading functions return types (herr_t). pthreads' callsBill Wendling2000-05-191-14/+13
| | | | | | | | | | | | | 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.
