* [svn-r13796] Description:Quincey Koziol2007-05-231-115/+0
| | | | | | | | | Clean up ISOHM code further and get rid of several non-optimal ways of working with object headers. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.9 (amazon)
* [svn-r13753] Description:Quincey Koziol2007-05-141-1/+1
| | | | | | | | | | | | | Check in "unique, but sharable" optimization to ISOHM code, which allows object header messages that are only used in one object to remain in the sole user's header, but migrates messages that are used in more than one header into the ISOHM heap. Tested on: Mac OS X/32 10.4.9 (amazon) FreeBSD/32 6.2 (duty) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13721] Description:Quincey Koziol2007-05-011-48/+113
| | | | | | | | | | | | | Add "fail if unknown" and "mark if unknown" flags to object header messages. This gives the library a clean way to tell older libraries that a message should not be just ignored if it's unknown, but that other actions should occur. Tested on: Mac OS X/32 10.4.9 (amazon) FreeBSD/32 6.2 (duty) FreeBSD/64 6.2 (liberty) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13591] Problem:Albert Cheng2007-04-051-1/+2
| | | | | | | | | | | 4294967296LL is not supported by older C like Windows VC6. Solution: /* use <= 2**32 -1 to stay within 4 bytes integer range */ HDassert(chunk0_size <= 4294967295UL); Platforms tested: kelgia, copper and osage.
* [svn-r13575] Problem:Elena Pourmal2007-04-031-1/+1
| | | | | | | | | | | dsets failed on kelgia with assertion failure in H5Ocache.c. Kelgia could not deal with the comparison of uint64_t variable with 4294967296 constant. Solution: By John's suggestions used suffix LL for the constant. Platforms tested: kelgia, kagiso, and smirom with icc compiler
* [svn-r13518] Description:Quincey Koziol2007-03-161-1/+8
| | | | | | | | Add some sanity checking to improve the resilience of the object header decoding in the face of a bad reference, or a corrupted file. Tested on: Mac OS X/32 10.4.9 (amazon)
* [svn-r13499] Description:Quincey Koziol2007-03-121-0/+5
| | | | | | | | Avoid storing the # of attributes in the "attribute info" message and regenerate it when the object is opened. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13498] Description:Quincey Koziol2007-03-121-0/+5
| | | | | | | | | Eliminate storing # of links in "link info" message, regenerate it when the object is opened instead. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)
* [svn-r13497] Description:Quincey Koziol2007-03-111-25/+36
| | | | | | | | | | | | | | | | | | Move ref. count of # of links to an object out of the object header's prefix and make it a header message instead (since it's a "rare" occurence), eliminating some more space for each object in the file. Inserting this "ref. count" message exposed a flaw in the library's mechanism for locating a message to promote to another chunk and replace with a continuation message, which required some additional work to fix. It's still not completely robust, but it's working for more cases now and detects failures robustly. Reduced the minimum size of an object header chunk to just enough to contain a header message prefix and continuation message. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13492] Description:Quincey Koziol2007-03-111-3/+5
| | | | | | | | | Fix mis-calculation of chunk #0 size encoding and also catch a few more places which adjust the size of chunk and have them adjust the encode flags also. Add some assertions to object header sanity checking routine. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13491] Description:Quincey Koziol2007-03-101-8/+50
| | | | | | | | Reduce the size of the value used to store the # of bytes in the "payload" for chunk 0 of an object header. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13487] Description:Quincey Koziol2007-03-101-11/+15
| | | | | | | | | Eliminate message count from new version of object header prefix - it can be computed when the header is loaded and the table of messages is built. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13486] Description:Quincey Koziol2007-03-101-26/+0
| | | | | | | | | Move attribute tracking information out of object header prefix and make it into a message that is inserted only when attributes are present on the object. Tested on: FreeBSD/32 6.2 (duty)
* [svn-r13477] Description:Quincey Koziol2007-03-081-6/+27
| | | | | | | | | | | | | | | | | | | | 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. Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 6.2 (duty)
* [svn-r13470] Description:Quincey Koziol2007-03-061-5/+13
| | | | | | | | Avoid storing the phase change values for attribute storage, unless they are non-default values. Tested on: Mac OS X/32 10.4.8 (amazon)
* [svn-r13466] Description:Quincey Koziol2007-03-061-0/+5
| | | | | | | | | Add some extra sanity checking to object header status flags read from file. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13449] Description:Quincey Koziol2007-03-041-9/+25
| | | | | | | | | | | | | Add object creation property (H5P[s|g]et_obj_track_times) to disable storing timestamps on objects, which makes the object's header size smaller. Also, added object header status flags to H5O_info_t struct (for H5Oget_info/H5Oget_info_by_idx) and cleaned up other field names in the struct as well. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)
* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r13250] Description:Quincey Koziol2007-02-071-0/+3
| | | | | | | | | | Add support for inserting attributes into creation order index. Also, update support for dense link & attribute storage in h5debug. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)
* [svn-r13248] Description:Quincey Koziol2007-02-061-1/+1
| | | | | | | | | More progress on creation order for attribbutes - they are now basically working for "compact" attribute storage. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)
* [svn-r13232] Description:Quincey Koziol2007-02-041-12/+5
| | | | | | | | | Remove the "scaffolding" for shared message method invocation and simplify the way shared messages are dealt with in general. Tested on: FreeBSD/32 6.2 (duty) Mac OS X/32 10.4.8 (amazon)
* [svn-r13182] Description:Quincey Koziol2007-01-231-1/+1
| | | | | | | | | Move filter pipeline message class to new "shared message interface" regime, along with minor fixups to implementation of calling that interface. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13178] Description:Quincey Koziol2007-01-231-1/+1
| | | | | | | | | | Figured out a way to phase in individual message class support for the new shared message "interface", so check that in before working on the message classes themselves. Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 6.2 (duty)
* [svn-r13176] Description:Quincey Koziol2007-01-231-1/+1
| | | | | | | | Push code further toward shared message method calling refactor. Tested on: FreeBSD/32 6.2 (duty) Too minor to require h5committest
* [svn-r13155] Description:Quincey Koziol2007-01-191-19/+40
| | | | | | | | | | | | | | Add "set_crt_index" and "get_crt_index" methods for the object header message class. Unify fractal heap definitions for shared messages and attributes, under "object header" fractal heap definitions. Initial code for adding creation order index to object header messages. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13100] Description:Quincey Koziol2007-01-031-8/+5
| | | | | | | | Fix bug which could possibly corrupt file data if an attribute was renamed to a longer name. Tested on: FreeBSD/32 6.1 (duty)
* [svn-r13098] Description:Quincey Koziol2007-01-021-3/+16
| | | | | | | Checkpoint changes for bug fix, to shift coding to another machine. Tested on: Linux/64 2.6 (chicago2)
* [svn-r13015] Description:Quincey Koziol2006-12-041-1/+1
| | | | | | | | | | | Migrate more object header routines to use the H5O_msg_ prefix and put them into the src/H5Omessage.c code module. Tested on: Mac OS X/32 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) AIX/32 5.? (copper)
* [svn-r12997] Description:Quincey Koziol2006-11-291-1/+1
| | | | | | | | | | Rename too generic "H5O_FLAG_<foo>" flags that are used as flags for header messages to "H5O_MSG_FLAG_<foo>", in order to make their use clearer. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir)
* [svn-r12994] Description:Quincey Koziol2006-11-291-1/+1
| | | | | | | | | | | | | | | Propagate object creation properties up into group, dataset and named datatype property lists, when those property lists are retrieved for existing objects in a file. Also, add H5Tget_create_plist() API routine, to allow named datatype property lists to be retrieved for named datatypes. Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) Linux/64 2.4 (mir) AIX/32 5.? (copper)
* [svn-r12992] Description:Quincey Koziol2006-11-281-3/+40
| | | | | | | | | | | | | | | | | | Add fields for tracking attributes on objects to object header prefix, when using the latest version of the format. Reduce size used to store type of header message from 2 bytes to 1. (If we have >256 message types, we probably have a different problem... :-) Also, add "birth" time for object (i.e. creation time) [named to align with similar fields in file systems] Correct bug in H5Gget_objinfo() - retrieve the ctime field from object info, instead of the mtime field. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12990] Description:Quincey Koziol2006-11-281-0/+13
| | | | | | | | | | | When using the latest version of the file format, move the "modification time" information into the object header prefix, which is more efficient. Also add "access time" and "change time" (for metadata) fields, all of which take about the same space as the previous modification time header message. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12973] Description:Quincey Koziol2006-11-251-0/+3
| | | | | | | | | | | | | | | Finish removing library's internal code that uses H5G_get_objinfo() and retarget it at either getting the link information or the object information, as appropriate. (Still need to add user-level tests for H5Oget_info(), but since several internal components of the library depend on the internal version, it appears to be working correctly). Tested on: FreeBSD/32 4.11 (sleipnir) Linux/322.4 (heping) Linux/64 2.4 (mir) AIX/32 5.? (copper) Mac OS X/32 10.4.8 (amazon)
* [svn-r12801] Description:Quincey Koziol2006-10-231-4/+11
| | | | | | | | | | | | Fix several errors in the "latest version" of the object header format changes and enable the new version when requested now. Clean up several confusing or duplicated sections of code. Tested on: Linux/32 2.4 (heping) Linux/64 2.4 (mir) FreeBSD/32 4.11 (sleipnir)
* [svn-r12774] Modified flush code in the metadata cache to allow it toJohn Mainzer2006-10-181-2/+8
| | | | | | | | | | | | | | | | | handle flush callbacks which can dirty other entries, and resize and/or rename the target entry. This feature is needed by the fractal heap code. Also added associated test code. H5Commit tested. Test failed on heping, but the error appears to be a syntax error in an un-related file. Tests on copper & sol passed, along with tests on phoenix.
* [svn-r12771] Description:Quincey Koziol2006-10-171-92/+107
| | | | | | | | | | | | | | | | | More fixes to make the I/O & memory operations more efficient when loading & flushing object header chunks. Add in concept of a chunk having a "gap" at the end - unused space that is not large enough to hold a full null message that describes it. Clean up formatting a bit. Latest version of object header format not enabled yet, still working on a few bugs... Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12770] Description:Quincey Koziol2006-10-161-273/+215
| | | | | | | | | | | | | | | Overhaul usage of object header chunks to reduce I/O operations and memory allocations. The object header prefix is now stored in the first object header chunk's "image" in memory. Also, lots of formatting cleanups. Taught h5debug tool about new object header format (which isn't enabled just yet). Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12761] Description:Quincey Koziol2006-10-161-36/+50
| | | | | | | | | | Refactor object header macros, in preparation for updating the format. Tested on: Mac OS/PPC 10.4.8 (amazon) FreeBSD/32 4.11 (sleipnir) w/thread-safe Linux/32 2.4 (heping) w/C++ & FORTRAN Linux/64 2.4 (mir) w/1.6 compat & build-all
* [svn-r12760] Description:Quincey Koziol2006-10-161-3/+253
| | | | | | | | | | | | Speculatively attempt to read in the entire first chunk in object header with the object header prefix. If successful (which it is most of the time), this reduces by 1 the # of I/Os required to read in the object header. Since the object header typically was taking 2 I/Os, this should cut the number of I/O operations when opening an object's header in half. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/C++ & FORTRAN
* [svn-r12756] Description:Quincey Koziol2006-10-121-34/+27
| | | | | | | | | | | | | | Clean up some object header code in advance of more major changes in the near future. Fix small initialization error in attribute message name buffer copy. Tweak down the default # of messages for new object headers. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Mac OS/32 10.4.8 (amazon)
* [svn-r12738] Description:Quincey Koziol2006-10-101-1/+1
| | | | | | | | Tweak down some of the static array definitions for new & re-loaded object header data structures, to reduce memory use in common cases. Tested on: Linux/32 2.6 (chicago)
* [svn-r12680] Description:Quincey Koziol2006-09-251-15/+15
| | | | | | | | | Review, revise & checkin in Peter's latest round of object copy changes, which add basic support for datasets & attributes with reference datatypes. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r12422] Purpose:Quincey Koziol2006-06-191-1/+6
| | | | | | | | | | | | | | | Bug fix Description: Don't attempt to merge object header messages when a file is opened read-only. Mark the object header dirty when messages are merged, as well as the particular message affected. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r12414] Purpose:Quincey Koziol2006-06-171-0/+1
| | | | | | | | | | | | | | | | | Bug fix Description: Fix bug which could lead to files with incorrect count of messages in the header for an object. The exact sequence of operations is complicated and is described in the release notes. Solution: Mark merged null header messages as dirty. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Mac OS/X (amazon)
* [svn-r11758] Purpose:Quincey Koziol2005-12-041-68/+78
| | | | | | | | | | | | | 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-r11712] Purpose:Quincey Koziol2005-11-151-0/+554
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.... :-)
