* [svn-r16670] Interrim checkin of journal file modifications supporting ↵John Mainzer2009-04-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | recognition and rejection of attempts to apply the wrong journal file to a corrupt HDF5 file. Specifically, I made the following changes: 1) Moved all journaling data into the journaling in progress superblock extension message. 2) Added a "magic number" to the journaling in progress message, with the same "magic number being added to the header of the associated journal file. 3) Modifications to library test code to support the above. 4) Modified h5recover to examine the supplied hdf5 file, determine if it is in fact a HDF5 file, if so determine if it is marked as having journaling in progress, and if it does, extract the contents of the journaling in progress super block extension message. 5) Modified h5recover to examine the supplied journal file, determine if it is in fact a HDF5 journal file, and if so, extract the data from its header. 6) Modified h5recover to refuse to apply the supplied journal file to the supplied HDF5 file unless the "magic numbers" obtained from these files matches. 7) Added an examine option to h5recover that causes it to examine and report on the supplied files, but do nothing. This option exists primarily to facilitate testing, but I expect that some users will find it useful as well. 8) Added test code to exercise items 4-7. Note that while I have tried to cover the more likely cases, this test code is extremely cursory. In particular, the code to examine the supplied HDF5 file is barely tested at all. Need a library of HDF5 files exibiting the full range of possible super block and super block extension message structures to test this properly. 9) In passing, tighened up the code that controls dumps of "possibly significant" differences between the contents of the control and recovered data sets in the h5recover. It should now ignore one integer matches in what appears to be garbage raw data. Tested: serial and parallel on Phoenix serial and parallel on Jam serial on Linew serial on Liberty All tests were done in debug mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Koziol2007-03-081-1/+2
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest

| | | | | | | | | | | | | | | | | Bug fix Description: Our previous "optimization" of metadata writing which only wrote metadata from one process was abusing MPI-I/O and after some consultation with Rob Ross and Rajeev Thakur, Albert & I have come up with a solution... Solution: Instead of only writing from one process, issue a collective write operation with all processes, for metadata writes. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

| | | | | | | | | | | | | | | | | Bug fix Description: When datasets are deleted from a file, they are removed from the sieve buffer, but instead of invalidating only the part of the sieve buffer affected, the sieve buffer code would throw away the entire sieve buffer, potentially including other raw data in the buffer that hadn't been written to disk yet. Solution: Improve the sieve buffer clearing code to handle partial invalidations. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest
