* [svn-r27768] Description:Quincey Koziol2015-09-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them. Tested on: MacOSX/64 10.10.5 (amazon) w/serial & parallel Linux/64 3.10.x (kituo) w/serial & parallel Linux/64 2.6.x (ostrich) w/serial

* [svn-r15796] Purpose: Close bug #1322Neil Fortner2008-10-071-3/+3

| | | | | | | | | | | | | | | | reference count > 1. 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). Test added for this case. Tested: kagiso, smirom, linew (h5committest)

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.
