* [svn-r15113] This checkin contains:John Mainzer2008-05-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Updates to test opening of a file created with journaling, along with associated debugging modifications. (Mike M. To get journal deletion to work correctly, I had to modify H5C2_jb__init() to allocate a buffer for the journal file name and copy it into the buffer. Similarly, I had to modify to H5C2_jb__takedown() to free the buffer. The fix was hurried, and should be reviewed. Also, a similar fix is probably in order for the HDF5 file name.) * Fix for the bug Albert reported on Linew. * An attempt to apply the changes Quincey requested to the loc_id parameters to the FUNC_ENTER_API_META macro calls in: H5Gmove2(), (src_loc_id --> dst_loc_id) H5Lcopy(), (src_loc_id --> dst_loc_id) H5Lmove(), (src_loc_id --> dst_loc_id) H5Glink2(), (cur_loc_id --> new_loc_id) H5Lmove() (cur_loc_id --> new_loc_id) However, with the exception of the requested change to H5Gmove2(), all these chages caused us to fail the regression tests. Thus only the H5Gmove2() change is made. Several caviats and warnings: * If you build and test this checkin, it will fail on the on the test for trecover. This showed up after I updated my project, so initially I thought I had broken something. However, after examining the problem for a while, I thought to checkout the version prior to this checkin, and test to see if the problem appeared. It did (under serial on phoenix, and parallel on Kagiso), so I am going ahead with this checkin regardless under the assumption that it is orthoginal to my changes. * Low level testing for the journaling feature of the metadata cache is not complete. The coverage of the existing tests is good enough that I don't expect anything major, but don't be surprised if you run into problems around the edges. In particular, enabling and disabling journaling while the file is open has not been tested at all. Suggest we stay away from this until it gets at least a once over. * The metadata journaling smoke check tests in cache2_journal.c are still configured to generate the architype files used to check journal output. This can be turned off any time, but given Quincey's constaints on test file size, I have to write code to skip the tests if the architype files are missing, and then put compressed versions of the architype files in svn before I do so. Unfortunately, there is no time before I leave. * I left a good bit of debugging code in both the journaling code proper, and the associated test code. It should all be #if 0'ed out at present, but if you run into it, you know what is going on. Needless to say, I'll delete it when I finish testing. * I was not able to reproduce the bug Albert observed on RedStorm locally, so I don't have a fix for it. That said, I touched some things that could have caused it, so it is possible that I fixed it by accident. Testing: Before I updated, I was able to build and test serial on Phoenix and Linew, and parallel on Kagiso without errors in the regression tests. As discussed above, after the update, I failed in the test for trecover in a serial build and test on Phoenix, and parallel build and test on Kagiso. Linew is slow, so I didn't attempt a test there. Since the same failures appear in the verion prior to this checkin, I am going ahead with the checkin regardless on the assumption that the problem is orthoginal to my changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch v1 B-tree nodes from using previous cache to use the new journaling cache code. This is a major switch for the cache callbacks. Switched the metadata caching code from having a pointer to the file it's in to receiving a pointer to the file, when needed. This was necessary in order to avoid crashing when two files IDs were open on the same underlying file and one of those files was closed with cache entries using the file pointers. Also took out the check in the caching code for reading off the end of the file, which didn't play nicely with the multi-file VFD. Switching the cache from having a pointer internally to requiring one externally meant tweaking almost all the test code. :-/ Added correct exit codes to cache2 tests that didn't have them already, so the 'make check' will stop when they fail. Use the path to the h5diff in this build in the tools/h5recover testing script, since we can't guarantee a user has HDF5 already installed. Assorted minor tweaks to get everything to compile more cleanly and pass all the tests (on my Mac :-). Tested on: Mac OS X (10.5.2) w/C++ (more testing coming up shortly, I just didn't have my "rsync testbed" set up for this branch when I started making changes to the code)

* [svn-r13477] Description:Quincey Koziol2007-03-081-0/+3
| | | | | | | | | | | | | | | | | | | | The main purpose of this checkin was to eliminate the space used for tracking creation time indices when there is no way they can be used (i.e. attributes can't be shared in the file and the user hasn't turned on attribute creation tracking), however there were some other minor changes which crept in: - Fix a cache locking deadlock when a shared attribute and one of its components end up in the same fractal heap direct block. (This is fixed the "slow" way for right now, until John has time to add support for readers/writer locking to the cache. - Optimize attribute copying when a copy will be kept during a v2 B-tree search. - When freeing a block on disk, attempt to merge it with the metadata and "small data" aggregators.

* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-0/+6
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.

* [svn-r12739] Added Direct I/O driver to VFD. It's only supported by SGI ↵Raymond Lu2006-10-101-1/+1
| | | | | | | | | | 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-r12708] Description:Quincey Koziol2006-10-031-0/+7
| | | | | | | | | | | | | | | | | | | Add the "use the latest version of the format" support to datatype messages. And a regression test to check that it's working. Also, found that we have been over-allocating space for compound datatype messages (when they have array datatypes or can use the latest version of the format) and trimmed the size back. Clean up datatype & dataspace encode/decode routines by having them allocate & release "fake" file structures, which gets them out of needing to "know" about the internals of file structures.

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.

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.... :-)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Description: See details from Bug #213. Family member file size wasn't saved anywhere in file. When family file is opened, the first member size determine the member size. Solution: Hopefully, this is the last step of checkin for this stage. This step mainly enables h5repart tool to be able to convert file driver from family to sec2. Because the library saves family information in file, in trying to convert to sec2 driver, the library simply change the address of driver information to undefined so that the driver information block can be ignored. This step also updates the reference manual of H5Pset_fapl_family() and h5repart. In the fifth step of checkin, backward compatibility with v1.6 is tested. A family file created was created with the v1.6 library and opened with this version of the library. In the fourth step of checkin, a test suit is added for h5repart, including a program to generate the test files, a script file to run h5repart, and a program to verify repartitioned files can be opened by the library. There's a change from the first step of checkin. Family name template is no longer saved in the superblock because different pathname can make the name different. In the third step of checkin, h5repart has been modified. If h5repart is used to change the size of family member file, the new size(actual member size) is saved in the superblock. In the second step of checkin, multi driver is checked against the driver name saved in superblock. Wrong driver will result in a failure with an error message indicating multi driver should be used. This change includes split driver because it's a special case for multi driver. In the first step of checkin. Family member size and name template(unused at this stage) are saved in file superblock. When file is reopened,the size passed in thrin superblock. A different size will trigger a failure with an error message indicating the right size. Wrong driver to open family file will cause a failure, too. Platforms tested: h5committest and fuss. Misc. update: doc/html/RM_H5P.html and doc/html/Tools.html

| | | | | | | | | | | | | | | | | | Bug fix Description: The "shared" raw B-tree node can get freed before all the B-tree nodes had been flushed out to disk and released by the cache. Solution: Implement a simple reference counting wrapper for objects in the library and use it to hold the shared raw B-tree nodes so they aren't freed before all references to them in memory are released. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modei4)
* [svn-r8823] Purpose:Quincey Koziol2004-07-071-0/+4
| | | | | | | | | | | | | | | Code optimization Description: Since the raw B-tree nodes are the same size and only used when reading in or writing out a B-tree node, move raw B-tree node buffer from being per node to a single node that is shared among all B-tree nodes of a particular tree, freeing up a lot of space and eliminating lots of memory copies, etc. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8613] Purpose:Quincey Koziol2004-06-051-61/+20
| | | | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance.

* [svn-r8600] Purpose:Quincey Koziol2004-05-311-1/+3
| | | | | | | | | | | | | Code optimization Description: Don't recompute the internal index value for looking up the chunk in the hash table, just use the value already computed from iterating through the chunks. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8158] Purpose:Quincey Koziol2004-02-061-16/+20
| | | | | | | | | | | | | | | | | Code cleanup/optimization Description: Query property list values once, at the beginning of the I/O routines, instead of querying the property list values multiple (lots!) of times in lower level routines. Solution: Create "property list caches" for internal library queries of the property list values. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-2/+1
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)

* [svn-r7471] Purpose:Bill Wendling2003-09-121-3/+2
| | | | | | | | | | | | | | | | | | | | | Update Description: The F_open and F_flush functions had a lot of cruft in them. The F_flush was being used as a way to allocate the superblock. The F_open had a bunch of code in there to read and serialize the superblock. Solution: Moved these out into their own functions. Platforms tested: Modi4 (parallel, Fortran) Copper (parallel, Fortran) Verbena (Fortran, C++) Sol (Fortran) Misc. update:
* [svn-r7381] Purpose:Quincey Koziol2003-08-181-10/+10
| | | | | | | | | | | Code cleanup Description: Various cleanups resulting from running lint tool over H5F.c source module Platforms tested: FreeBSD 4.8 (sleipnir) too minor to require h5committest
* [svn-r7316] Purpose:Quincey Koziol2003-08-081-2/+0
