* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-021-41/+172
| | | | | | | | | | | | | | Users can create external links using H5L_create_external(). These links point to an object in another HDF5 file. Users can alter the behavior of external links or create new kinds of links by registering callbacks using the H5L interface. Added tests, tools support, etc. Also a number of other, minor changes have been made (some restructuring of the H5L interface, for instance). Additional documentation and examples are forthcoming.

* [svn-r12452] Purpose:James Laird2006-07-051-939/+71
| | | | | | | | | | | | | | | | | | | | | | Feature Description: Revised Link APIs. Solution: New link APIs use H5L* H5*create_expand do not create links to the objects created; this must be done manually with H5Llink. Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy), and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query API (H5Lget_linkinfo instead of H5Gget_objinfo). All old APIs are still supported in H5Gdeprec.c . Platforms tested: sol, mir, copper Misc. update: Forgot to update MANIFEST and release docs. Will do after checkin.

| | | | | | | | | | | | | | | "Hide" file format changes (for now) Description: Add ifdef's (controlled by the --enable-group-revision configure flag) to disable group revision changes to the file format, in order to allow alpha release to go ahead without releasing an unsupported version into the wild.

* [svn-r12191] Purpose:Quincey Koziol2006-04-021-6/+8
| | | | | | | | | | | | | Bug fix Description: Correct the handling of the group creation property list when copying objects with the "create intermediate groups" flag. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest (once I pay attention to the compiler warnings... :-)
* [svn-r12189] Purpose:Quincey Koziol2006-04-011-40/+152
| | | | | | | | | | | | | | New/expanded features Description: Check in Peter's changed for the object copy code: - Allow/fix copying datasets using named variable-length datatypes - Start adding framework for property list to control how object copying occurs. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11838] Purpose:Quincey Koziol2005-12-261-114/+116
| | | | | | | | | | | | | | | | Bug fix Description: Retrieving an object's name could fail (in various ways) under certain circumstances (mostly having to do with mounted files). Solution: Re-write & simplify "get object name" code to fix error in a better way than adding yet another hack to the previous pile of hacks... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11758] Purpose:Quincey Koziol2005-12-041-41/+0
| | | | | | | | | | | | | New feature Description: Add in a combination of Peter's & my code to support copying variable-length data from one file to another, although currently only supported with contiguous data storage. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11738] Purpose:James Laird2005-11-181-1/+3
| | | | | | | | | | | | | | | | | | | Configure feature Description: Added 'make trace' target. Solution: Added tracing to 1.7. This was done automatically in 1.6, but left out of 1.7 until now (oops!). Tracing in 1.7 only happens manually, when the user types 'make trace.' Tracing automatically requires more framework than it's worth. I also fixed a couple of tracing bugs and ran trace. Platforms tested: mir, sleipnir, modi4 Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r11686] Purpose:Quincey Koziol2005-11-071-2/+108
| | | | | | | | | | | | | | | | | | | New feature Description: Add in baseline "object copy" code from Peter [in the form of a new API routine: H5Gcopy()]. There's still some work to do (like handling variable- length datatypes and possibly support for references) and it hasn't been tested on mounted files yet, but the core functionality is there and working correctly. I've also got a set of patches to update the 1.6 branch with tweaks to keep the branches mostly in sync, but Elena will kill me if I import them before the 1.6.5 release is out... :-) Platforms tested: FreeBSD 4.11 (sleipnir) h5committested
* [svn-r11490] Purpose:Quincey Koziol2005-10-031-4/+32
| | | | | | | | | | | | | | | Bug fix Description: Fix "double root open" bug and apply same fix to datasets & named datatypes. Also fix bug in symbol table entry lookup code that would "transfer" an object from one file handle to another file handle when the two file handles were opened on the same actual file. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11386] Purpose:Quincey Koziol2005-09-121-56/+102
| | | | | | | | | | | | | | Code cleanup/reorganization Description: Merge back some more changes extracted from the "compact group" set. This bunch cleans up and prepares the H5G_* routines for eventual import of new features. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Mac OS X.4
* [svn-r11384] Purpose:Quincey Koziol2005-09-121-2/+5
| | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Merge back changes from "compact group" work that improve the infrastructure of the library and may impact others. In this round of merging, that includes: - Move datatype allocation into single internal routine, instead of duplicated code that was spread out in a dozen or so places. - Clean up guts of object header routines (H5O_*) to allow for some of the fancieroperations that need to be performed on groups, along with some general improvements. - Added a new error code - Some minor cleanups in other code....

* [svn-r11304] Purpose:Quincey Koziol2005-08-271-7/+7
| | | | | | | | | | | | | Code cleanup (sorta) Description: Adjust H5G_stat_t to prepare for eventual "external link" information. This also puts the information for regular objects and soft links into more obviously separate places. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4
* [svn-r11300] Purpose:Quincey Koziol2005-08-251-2/+3
| | | | | | | | | | | | Code cleanup Description: Prevent memory leak when too many links are traversed. Also add test to traverse too many links. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4
* [svn-r11283] Purpose:Quincey Koziol2005-08-201-31/+30
| | | | | | | | | | | | | | | | Code cleanup Description: Clean up code somewhat: - Move from HDmemset() -> H5G_ent_reset() to clear out group entry info - Simplify H5G_unlink() call - Use portability macros instead of direct system calls in more places - Improve readbility by neatening whitespace, etc. - Move some macros into source code module instead of header files Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4

* [svn-r11229] Purpose:Quincey Koziol2005-08-101-2/+7
| | | | | | | | | | | | | | | | Big fix Description: A group opened by dereferencing a object reference would not work for H5Giterate(), due to the local heap & B-tree information not being cached. Solution: Get the local heap & B-tree info & point to that structure instead of the group entry for the group. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11219] Purpose:Quincey Koziol2005-08-081-87/+50

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:

* [svn-r10837] Purpose:Quincey Koziol2005-06-011-0/+5
| | | | | | | | | | | | | | | | | | | | | Bug fix/new feature Description: Setting "SEMI" or "STRONG" file close degrees causes problems when multiple file IDs exist for the same file on disk. Solution: Make the "SEMI" and "STRONG" settings only apply to the file ID that is being closed. Also, add an "H5F_OBJ_LOCAL" flag for the H5Fget_obj_count() & H5Fget_obj_ids() calls, so that applications can query about objects opened with a particular file ID instead of all the objects opened in the file on disk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

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