* [svn-r30306] Updated vfd test to be better about fapls and h5_reset().Dana Robinson2016-08-191-72/+110
| | | | | | | | | | | Prevents the test from segfaulting in other sub-tests when a previous test fails. Tested on: 64-bit Ubuntu Linux 16.04 LTS w/ gcc 5.4.0 Autotools serial + direct VFD (vfd test only) Also tested with a forced error to ensure that the test no longer segfaults and confirmed that all test files are cleaned up.
* [svn-r30297] Changed FAIL_STACK_ERROR to TEST_ERROR in test/vfd.c.Dana Robinson2016-08-181-51/+51
| | | | | Tested on: 64-bit Ubuntu Linux 16.04 LTS w/ gcc 5.4.0 Autotools serial, vfd test only
* [svn-r30184] Converted h5_fileaccess() to H5Pcreate() in the sec2 test.Dana Robinson2016-07-141-1/+2
| | | | | Tested on: 64-bit Ubuntu Linux 16.04 LTS w/ gcc 5.4.0 Autotools serial, vfd test only w/ various VFDs
* [svn-r30163] Changed a h5_fileaccess() call to H5Pcreate() in the core VFD test.Dana Robinson2016-07-091-1/+2
| | | | | | | | | | Since it only tests the core VFD, there's no need to get a VFD-dependent fapl. Tested on: 64-bit Ubuntu Linux w/ gcc 5.3.1 vfd test w/ all VFDs tested by make check-vfd

* [svn-r27768] Description:Quincey Koziol2015-09-141-181/+199
| | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them. Tested on: MacOSX/64 10.10.5 (amazon) w/serial & parallel Linux/64 3.10.x (kituo) w/serial & parallel Linux/64 2.6.x (ostrich) w/serial
* [svn-r24993] Purpose:Dana Robinson2014-04-091-0/+13
| | | | | | | | | | | | | | | Adds write tracking to the core VFD, which can be configured via the H5Pset/get_core_write_tracking() API call. When enabled and writing to the backing store is enabled, this feature will track writes and only write out the changed bytes on flush/close. Tested on: 32-bit LE linux (jam) w/ Fortran and C++ 64-bit BE linux (ostrich) 64-bit Darwin 12.5.0 (kite) All were tested using the core VFD w/ paging on (core_paged in the VFD list). Make check-vfd was also tested on jam.

Fixed by using STDOUT_FILENO and redesign parse_command_line and main to cleanup file allocations. The output_file var is null when using stdout. In cleanup do not close output_file if NULL. r20510: Initialize ufid = -1 and predicate HDclose call on ufid != -1 r20511: Purpose: Fix coverity issue 1715 Description: Free "file" and nested data on failure in H5FD_core_open. r20512: Initialize ifid = -1 and predicate HDclose call on ifid != -1 r20514: Initialize h5fid = -1 and predicate HDclose call on h5fid != -1 r20516: Added else branch to the if (ret_value < 0) check. r20522: Addressed coverity issues 930-933, 850, 836, 835, 1307. All minor potential buffer overwrite bugs, or coverity errors. Fixed by replacing strcpy and sprintf with strncpy and snprintf. r20523: fixed coverity issues 68, 1120, 1116i r20524: Check H5Z_SZIP->encoder_present < 1 assuming 0 represents absence. r20601: Purpose: Fix coverity issues 1703-1705 Description: Modified the cleanup code in test_free in accum.c to reset allocated buffers to NULL after they are freed, and modified the error cleanup code to check if these buffers are NULL before freeing them. Also fixed some unrelated warnings in accum.c. r20602: Use HDsnprintf and HDstrncat r20603: Purpose: Fix coverity issues 808-809 Description: Modified test_core in vfd.c to check the returns from malloc, and keep track of whether points and check are allocated by setting them to NULL when they are not. Added code to free points and check on error if they are not NULL. Also fixed unrelated warnings in vfd.c. r20604: Use HDstrncpy. r20605: Use HDstrncpy and HDstrncat. r20606: Purpose: Fix coverity issue 807 Description: Modified long_compact in stab.c to keep track of whether objname is allocated by setting it to NULL when it is not. Added code to free objname on error if it is not NULL. r20607: Changed string function calls to use versions that specify the string length to fix coverity issues 832 and 839. Tested on: Mac OSX/64 10.8.2 (amazon) (Too minor to require h5committest)

| | | | | | | | | | | | | whole MULTI file saved in the super block. We took it out in v1.8 library because it's meaningless for the MULTI file. v1.8 library saves the EOA for the metadata file, instead. But this caused some backward compatibility problem. v1.8 library couldn't open the file created with v1.6 library. I fixed the problem by checking the EOA value to detect the file created with v1.6 library. Tested on jam, koala, and heiwa.

| | | | | | to fail on some platforms. The problem was that the test was a clone of the SEC2 test. The SEC2 test accepts a file descriptor (int) via a void pointer from H5Fget_vfd_handle() whereas the STDIO test needs to accept a FILE pointer. Storing the FILE pointer in an integer failed on some systems. The STDIO test now stores the file handle in FILE pointer and checks it for NULL instead of < 0.

* [svn-r12766] Made two changes to Direct I/O VFD: first added 3 parameters to ↵Raymond Lu2006-10-161-2/+3
| | | | | | | | H5Pset_fapl_direct to control memory boundary, file block size, and maximal copy buffer size; second in H5FD_direct_write and H5FD_direct_read, the library checks whether data buffer is aligned. If it is, then write and read the data directly instead of making a copy buffer.
* [svn-r12739] Added Direct I/O driver to VFD. It's only supported by SGI ↵Raymond Lu2006-10-101-0/+84
| | | | | | | | | | Altix (cobalt). There's a configure option --enable-direct-vfd/--disable-direct-vfd to enable/disable Direct I/O support. The default is enabled. There's a small test in test/vfd.c. Another way to test it is to set environment variable HDF5_DRIVER to "direct" and run "make check" in the test/ directory. There'll be some further improvement in the following checkin including allowing user to provide memory boundary value, file block size, and copying buffer size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)

| | | | | | | | | | | | | | | | | Avoid bug for family file driver backward compatibility with 1.6. Description: Because there is no srcdir on windows, string pathname should be initialized as NULL before using strcat. Solution: Changed the code as above. Platforms tested: too minor to test. Misc. update:
