* [svn-r16710] Purpose: Fix bug 1423Neil Fortner2009-04-081-2/+4
| | | | | | | | | | | | | | Description: Versions of the library between 1.3.0 and 1.6.3 have a bug which prevents them from opening any file that does not have the root group's symbol table information cached in the root group's entry in the superblock. Prior to 1.8 this was not an issue as this information was always cached. However, 1.8.0 stopped writing this information (which is not required by the file format specification), and these older versions can therefore not read files created or last written by versions 1.8.0 to 1.8.2. This fix modifies the library to once again add this information to the superblock (when using the old file format). Tested: jam, linew, smirom (h5committest)
* [svn-r16611] In previous checkin (r16609), the flag "write_driver" wasn't ↵Raymond Lu2009-03-251-1/+0
| | | | | | | | necessary as Quincey pointed out. I took it out and used the driver address instead. Tested on jam - simple change.
* [svn-r16609] Bug fix (#1161): When a family file created with v1.6 library ↵Raymond Lu2009-03-241-0/+1
| | | | | | | | | | | is opened and closed with v1.8 library, v1.8 library writes the driver info block in the superblock. But v1.6 doesn't write it. This caused the data after the superblock to be overwritten. The solution is to use a flag to indicate when the original file doesn't have the driver info, v1.8 library doesn't write it either. Tested on jam. I have some trouble to access smirom and linew using h5committest.
* [svn-r16594] Purpose: fix bug 1189Neil Fortner2009-03-231-1/+2
| | | | | | | | | | | Description: Some files apparently exist in the wild which have corrupt symbol table messages on the root group. These files can be opened by 1.6 (which uses the cached information in the superblock) but not by 1.8. This patch fixes 1.8 and 1.9 so they can now open these files, and will correct them if necessary. Also fix some potential (rare) problems with array datatype versions. Tested: jam (parallel; h5committest not working on linew or smirom)
* [svn-r16062] Purpose: Allow per-dataset rdcc configurationNeil Fortner2008-11-121-1/+1

* [svn-r15451] Purpose: Fix various problems that were occurring when using ↵Neil Fortner2008-08-071-18/+19
| | | | | | | | | | | | | | | | mounted files. Description: Moved mount table from top file structure to shared file structure. Moved parent out of mount table and back into top file structure. Mounted files can now be accessed from any handle of the parent file. Changes to how files are closed. Stricter cycle checking on mounted files. Removed unused function H5F_has_mount(). Tested: committest in 1.8 branch. Committing now due to the urgency of the fix. No changes here are specific to the trunk, but I will keep an eye on the daily tests.

* [svn-r13978] purpose:Vailin Choi2007-07-131-0/+3
| | | | | | | | | | | | | | New feature. Description: Added routines to report on the amount of storage for: 1) 1.6 btree and heap storage info for groups 2) 1.8 btree, fractal heap storage info for groups, attributes and SOHM table 3) btree storage for chunked datasets 4) 1.8 superblock extension size.

* [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.

| | | | | | | | | | | | | | | | | | | Revise latest form of superblock format pretty drastically, to eliminate unused fields and move rarely used fields into superblock extension. Finished removing last vestiges of references to (never used) i"shared" object header message ID. Added object header messages for non-default v1 B-tree 'K' values and for driver info. Updated testfiles to reflect size changes, etc. Various minor cleanups, etc. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)

| | | | | | | | | object header information, rather than storing it directly in the superblock. This should make future updates to the superblock much less painful. Tested on Windows, kagiso, and smirom.
* [svn-r13153] Added checksum to superblock and driver info block (in latest ↵James Laird2007-01-181-5/+52
| | | | | | | | | | | version of superblock). Tried to standardize sizes and added #defines to H5Fpkg.h so that hopefully the code is a little easier to read. Of course this is a file format change. Tested on Windows, juniper, smirom, kagiso.
* [svn-r13116] Description:Quincey Koziol2007-01-061-0/+6
| | | | | | | | | | | | Add support for deleting all the attributes on an object, when they are dense and possibly shared. Also, add some testing routines, for better error detection. Should fix daily test failures also... Tested on: FreeBSD/32 6.1 (duty)

* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-0/+1
| | | | | | | | | | | | 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-r12708] Description:Quincey Koziol2006-10-031-5/+16
| | | | | | | | | | | | | | | | | | | 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. Other minor whitespace/formatting cleanups, etc. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r11490] Purpose:Quincey Koziol2005-10-031-0/+1
| | | | | | | | | | | | | | | Bug fix Description: Fix "double root open" bug and apply same fix to datasets & named datatypes.

* [svn-r11022] Purpose:Quincey Koziol2005-07-051-0/+14
| | | | | | | | | | | | | | | | | | | | 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-r10971] Purpose: Bug fixRaymond Lu2005-06-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | Add API calls allowing user control of the metadata cache. Description: Prior to this update, the metadata cache was not configurable from outside the library. Solution: Add API calls allowing the user to configure the metadata cache either at file open time, or for any open file. Also added calls permitting the user to monitor cache size and hit rate. These latter facilities are needed for "manual" cache size control Platforms tested: h5committested Misc. update:

| | | | | | | | | | | | | | | | | | | | Code optimization Description: Refactor B-tree code to extract all common information for a B-tree into a shared structure that is pointed to by all the nodes in tree (instead of being included in each node). Also re-order B-tree node comparison checks for chunked datasets to check for >= the upper node first, since the comparison is a bit "heavy" and this check is more likely to succeed when you are adding records to the dataset. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest (also, recent h5dump commits have broken testing...)
* [svn-r8844] Purpose:Quincey Koziol2004-07-091-1/+2
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
