* [svn-r22601] Purpose: Fix HDFFV-5853Neil Fortner2012-07-251-2/+2
| | | | | | | | | | | | | | Description: When jumping out from between H5_BEGIN_TAG and H5_END_TAG macros using HGOTO_ERROR or HGOTO_DONE, the previous metadata tag is not reset on the dxpl. This could cause problems when, for example, calling H5Ocopy within an H5Literate callback. Added new HGOTO_ERROR_TAG and HGOTO_DONE_TAG macros which must be used in place of the above between H5_BEGIN_TAG and H5_END_TAG. Tested: jam, koala, ostrich (h5committest), durandal
* [svn-r21923] Description:Quincey Koziol2012-02-101-17/+17

Bring changes from Coverity branch to trunk: r20085: Purpose: Fix coverity issue 793 Description: Modified H5S_hyper_project_simple_higher() to free the entire span list in new_space on failure. r20091: This is a fix for coverity bug #1683. Changed the two printfs to use %lu (unsigned long) for printing "dset_size". r20162: Purpose: Fix coverity issue 785 Description: Modified H5T_enum_nameof() to free "name" on failure if it was allocated. Also clarified some code in H5S_hyper_rebuild_helper(). r20189: Addressed coverity defect 783. H5SL_new_node() in H5SL.c was failing to free space allocated in its first alloc if the second alloc failed. Added a call to H5FL_FREE to address this issue. This is purely to keep coverity happy -- if this code is ever triggered, we have much larger problems. Note that this fix will trigger an unused return value complaint from coverity next week. r20190: Fixed Coverity issues 1561 1565 and 1678 (UNUSED_VALUES) by moving checks of return values to after the function call. r20191: Fixed coverity issues 643 644 and 1678 (CHECKED_RETURN). r20232: Addressed coverity issues 923-925. Replaced calls to sprintf with calls to HDsnprintf. r20233: Fix coverity issue 662. Don't try to sort 0 attributes in H5Aint.c. r20234: Fix coverity issue 664. Check for NULL before dereferencing in H5Gdeprec.c. r20271: Purpose: Fix coverity issue 784 Description: Modified H5_debug_mask() to keep a list of files opened for use as a debugging output stream, and modified H5_term_library to close these files on exit. r20272: addressed coverity issues 838 & 955. Issue was use of strcpy() -- existing code was safe, but modified to use strncpy() to keep coverity happy. r20273: Addresed coverity issues 1388 and 1389. Initialized sel_iter->type to NULL in H5S_select_iter_init. r20275: Purpose: Fix valgrind issue in mf.c Description: Fixed bug (incomplete if statement) in test_mf_fs_alloc_free() so the retrieved node gets freed.

| | | | | | | | | | | | | | | | | | | | | | | Commit metadata tagging framework. Description: This check-in contains a new framework whose goal is to apply a tag value to each new entry in the metadata cache as it is created. This tag value is such that it relates each piece of metadata to the HDF5 object that it belongs to (dataset, group, et cetera). This changeset includes the framework that applies the tags as well as a suite of tests to verify correct tag application, though does not yet make use of the tag values to flush/evict individual objects. Please refer to the "flush/evict individual objects" RFC for further discussion of these changes. Tested: jam, amani, linew (h5committest) liberty, abe, blue print

Description: Added a new field 'app_count' to H5I_id_info_t struct, to track the reference count on an id due to the application. the old 'count' field tracks the total. Generally any id visible to the application gets placed in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref, H5I_register, H5I_clear_type, and a few other functions, to specify whether the operation(s) being performed on the id(s) are due to the application (TRUE) or not (FALSE).

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

| | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 32-bit (heping) Linux 2.4 64-bit (mir) Solaris 2.9 (shanti)
* [svn-r11886] Purpose:Quincey Koziol2006-01-231-2/+1
| | | | | | | | | | | | | Code cleanup Description: Check in some of the code cleanups from working on the external link support. (This doesn't include any of the external link features) Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX.4 (amazon) Linux 2.4
* [svn-r11838] Purpose:Quincey Koziol2005-12-261-27/+26
| | | | | | | | | | | | | | | | 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

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.... :-)
