* [svn-r14115] Description:Quincey Koziol2007-08-281-2/+2
| | | | | | | | | | | | | | | | | Remove all plain calls to H5Gopen() from source, replacing them with either H5Gopen2(). Add test for H5Gopen1(). Reformatted several pieces of code, to clean them up. Tested on: FreeBSD/32 6.2 (duty) FreeBSD/64 6.2 (liberty) Linux/32 2.6 (kagiso) Linux/64 2.6 (smirom) Solaris/32 5.10 (linew) Mac OS X/32 10.4.10 (amazon)
* [svn-r13588] A support of files bigger than 2GB for STDIO driver. Configure ↵Raymond Lu2007-04-041-5/+6
| | | | | | | | will check if fseeko is available. Using it instead of fseek can support big files because the offset is of type off_t not long int. Also added the test for STDIO in big.c.
* [svn-r13517] To deal with the situation that compiler supports direct I/O ↵Raymond Lu2007-03-151-2/+9
| | | | | | but file system doesn't, added a condition check of writing aligned data. Skip the test for direct VFD if it's this situation.
* [svn-r13432] Changed the detection of alignment requirement for Direct I/O ↵Raymond Lu2007-02-281-6/+0
| | | | | | from configuration to run-time detection in H5FD_direct_open in H5FDdirect.c.
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.

* [svn-r13139] Fixed the MULTI problem (Bug #731) that corrupted the data. ↵Raymond Lu2007-01-121-6/+55
| | | | | | | The problem came from the EOA for the whole MULTI file. It's taken out because it's meaningless for MULTI file. Instead, each individual file has its EOA.
* [svn-r13001] Enabled CORE file driver to read or write an existing file ↵Raymond Lu2006-11-301-0/+135
| | | | | | | depending the setting of backing store through H5Pset_core_fapl and file open flag. Added test cases in vfd.c.
* [svn-r12870] Add a new macro H5_HAVE_DIRECT_ALIGN in configure.in. Some ↵Raymond Lu2006-11-061-0/+6
| | | | | | | systems like copper and sleipnir doesn't require alignment for Direct I/O. If this's true, write or read data just like sec2 does.
* [svn-r12822] H5Pset_alignment seems working. Added it in test/vfd.c and ↵Raymond Lu2006-10-281-2/+121
| | | | | | made the test more complete by writing two data sets. One is aligned, and the other isn't.
* [svn-r12820] Added fragmental copy buffer to H5FD_direct_write. This buffer ↵Raymond Lu2006-10-271-4/+4
| | | | | | | size is set through H5Pset_fapl_direct. It's been added to H5FD_direct_read in the previous checkin. Still, a test is needed at later checkin.
* [svn-r12776] The internal change is to make the 3 parameters of ↵Raymond Lu2006-10-181-1/+13
| | | | | | | | H5Pset_fapl_direct be a structure and passed through driver info functions in H5FD_direct_open, H5FD_direct_read, and H5FD_direct_write. The external change is to add a new API function H5Pget_fapl_direct to query 3 control values, the memory boundary, file system block size, and the maximal buffer size for copying data.
* [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.
* [svn-r12705] Description:Quincey Koziol2006-10-021-9/+13
| | | | | | | | | | | | Fix file handle destroy routine to not attempt to flush out partially initialized file handles (when opening a file fails). Tested on: (until they finished testing, this time... :-) FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/64 2.4 (mir) w/1.6 compat Linux/32 2.4 (heping) w/FORTRAN & C++ Mac OSX/32 10.4.8 (amazon)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.... :-)
* [svn-r11562] Purpose:MuQun Yang2005-10-141-0/+1
| | | | | | | | | | | | | | | | | 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:
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-71/+71
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11022] Purpose:Quincey Koziol2005-07-051-0/+2
| | | | | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Don't unmount child files from a parent file if the parent file is being held open by an object. Also, moved the mounting routines into their own source file and the superblock routines into their own file also. Solution: Moved the code for unmounting child files down in the H5F_close routine and also add checks to the file and group mounting code to unmount child files when the last object holding open a file closes. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r10979] Purpose:Albert Cheng2005-06-241-0/+739
Renamed file_handle.c as vfd.c since its tests have evloved from merely file handles tests to other basic features of VFD's. Did some minor cosmetic changes in vfd.c. Updated Makefile.am with the new name. Makefile.in is regenerated. Platforms tested: In heping only since the changes are trivial. Misc. update:
