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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Improve ADF/CGNS benchmark by reducing the number of internal attribute copies made during creations, opens and writes. Added new H5O_iterate() routine for iterating through messages of a certain type in the object header (attributes are the only message currently that can have multiple instances in the object header).

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-24/+17
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly.

| | | | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance.

* [svn-r8590] Purpose:Quincey Koziol2004-05-271-99/+211
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage.

* [svn-r7538] Purpose:Quincey Koziol2003-10-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes and code cleanup Description: Lots of changes here: - Fixed bug #691 - when shared datatypes are used in attributes they are incorrectly copied into the attribute instead of referring the the named datatype in the file. This required bumping the version of the attribute message. The new version of the attribute message is only written out when a shared datatype is used in the attribute. [Also, this format change made the size of the attribute smaller.] - Added information to attribute debugging routine so that shared datatypes are displayed correctly with the h5debug tool. - Refactored the H5O* routines to extract code that was common to several routines into subroutines to call. - Added 'link' method for H5O message sub-classes, which increments the link count on shared objects when a message is created which shares them. - Corrected [unreported] bug where the link count was not being decremented on the shared object when a object header message with a reference to that object was deleted from the file. - Reduced size of shared message from 49 bytes (which was incorrect anyway and should have been 48 bytes) to 10 bytes, which required bumping the version of "shared" messages. - Refactored some of the shared datatype routines to allow for easier queries of "committedness" internally to the library and also added routine to easily increment/decrement the reference count of a shared datatype.

Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix/Code cleanup/New Feature Description: Correct problems with writing fill-values to external storage and allocate the data storage at the correct times. Also, mostly straighten out the strange code which allocates and fills raw data storage for datasets. Things are still a bit odd in that the fill-values for chunked datasets are written when the space is allocated, instead of in a separate routine, but there are two reasons for this: it's inefficient (especially in parallel) to iterate through all the chunks twice, and (more importantly) the space needed to store compressed chunks isn't known until we've got a buffer of compressed fill-values ready to write to the chunk. Additionally, add in the H5D_SPACE_ALLOC_INCR and H5D_SPACE_ALLOC_DEFAULT setting for the "space time", which incorporate the previous behavior of the space allocation for chunked datasets. The default settings for the different types of dataset storage are now as follows: Contiguous - Late Chunked - Incremental Compact - Early This checkin also incorporates a change to the behavior of external data storage in two ways - fill-values are _never_ written to external storage (under the assumption that writing fill-values is triggered by allocating space in an HDF5 file, and since space is not allocated in the file, the fill-values should not be written) and external data files are now created if they don't exist when data is written to them. The fill-value will probably need to be revisited at some time in the future, this just seemed like the safer course currently. I think I cleaned up some compiler errors also, before getting bogged down in the fixes for the space allocation and fill-values. Platforms tested: FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64 6.5 (modi4) in serial & parallel shortly.

| | | | | | | | | | | | | Code cleanup Description: Changed the last HRETURN* statements in the FUNC_ENTER macros into HGOTO* macros, which reduces the size of the library binary in certain configurations by another 10% Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel, IRIX64 6.5 (modi4) serial & parallel
* [svn-r5842] Purpose:Quincey Koziol2002-08-081-24/+30
| | | | | | | | | | | | | | | | Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-6/+6
| | | | | | | | | | | | | | | | Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.
* [svn-r5170] Raymond Lu2002-04-111-5/+22
| | | | | | | | | | | Purpose: New feature Description: Fill-value's behaviors for contiguous dataset have been redefined. Basicly, dataset won't allocate space until it's necessary. Full details are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment. Platforms tested: Linux 2.2.
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-7/+7
| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

Added a test to make sure that reading a file that has a dataset with a space with too large a rank fails. Actually, this one is a little weird: the code that reads the data space message assumes the space is scalar if the message cannot be read. Fortunately the layout message fails also, preventing the dataset from being opened. However, since the data type message is still visible h5ls will report that the object is a named data type. ./test/space_overflow.c [NEW] This is the little program that makes the th5s.h5 file. ./src/H5A.c ./src/H5R.c ./src/H5Sselect.c Updated trace info. ./src/H5Olayout.c ./src/H5Osdspace.c Added code to fail if the dimensionality is too large when decoding a layout or simple data space message. ./src/H5Oprivate.h Redefined H5O_LAYOUT_NDIMS in terms of H5S_MAX_RANK. ./src/H5P.c ./src/H5S.c Check for ndims>H5S_MAX_RANK in API function calls, added assert to internal functions. ./src/H5V.c Changed a `<' to an `<=' in an assert. ./test/flush2.c Includes stdlib.h for getenv(). ./tools/h5tools.c Able to handle up to H5S_MAX_RANK dimensions during output.

The `x' was removed from the name to remind us of that: H5MM_xmalloc() -> H5MM_malloc(), etc. H5MM_calloc() takes one argument like H5MM_malloc() instead of two like calloc() because we almost always called it with `1' for one of the arguments anyway. The only difference between the two functions is that H5MM_calloc() returns memory which is initialized to zero. ./src/H5Gent.c ./src/H5Gprivate.h Removed H5G_ent_calloc() since it wasn't used. ./src/H5Fistore.c Fixed a bug found by Albert. Thanks, Albert! This fix combined with the changes to memory allocation prevent the library from failing an assertion if the application uses an unreasonable size for chunks (like Alberts 10000x10000x4). ./src/H5MF.c ./src/H5MFprivate.h Changed H5MF_free() to H5MF_xfree() since calling it with an undefined address is allowed.

Fixed some data type memory leaks during error recovery. ./src/H5Dprivate.h Added H5D_typeof() similar to H5D_entof() that returns a pointer directly to the dataset's type. This is used by H5Tcopy() when invoked on a dataset (see below). ./src/H5Epublic.h Fixed typos in H5E_BEGIN_TRY and H5E_END_TRY macros. ./src/H5F.c Closing a file with objects still open reports the file name in the warning message. Removed unnecessary invalidation of shared data types. ./src/H5Gent.c ./src/H5Gpkg.h ./src/H5Gprivate.h Added `const' to some arguments. ./src/H5O.c ./src/H5Oprivate.h ./src/H5Oshared.c An object header message can now be a pointer to a message in some other object header. The pointer is to the first message of the appropriate type in the other object header and hard link counts are maintained automatically to prevent dangling pointers. The old global heap method of message sharing is also supported although nothing actually uses it. ./src/H5Oattr.c ./src/H5Ocomp.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Olayout.c ./src/H5Oname.c ./src/H5Osdspace.c ./src/H5Oshare.c ./src/H5Ostab.c Changed the data type for the shared message info struct to H5O_shared_t and added an extra initializer to the class methods struct for the set_share method. ./src/H5Odtype.c Added the ability to share data type messages by pointing to other object headers. ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added named data types and changed the functionality of some API functions as follows: * The term `read-only' means that a type handle cannot be modified with functions like H5Tset_*() or H5Tinsert(). * The term `immutable' means the same as `read-only' with the added restriction that H5Tclose() cannot be called for the type. A transient type is made immutable by calling H5Tlock(). * Handles to named types are always read-only. * Handles to predefined types are immutable. * A transient type can be converted to a named type by calling H5Tcommit(). This function will fail if the type is already named or is immutable. * The API function H5Tcommitted() returns an indication of whether a data type has been commited (or is named). If H5Tcommitted() returns TRUE for a data type obtained by calling H5Dget_type() on a dataset, then the dataset is using a shared data type. * H5Topen() returns a handle to a named type. * H5Tcopy() always returns a handle to a modifiable transient type even when invoked on a named type. Also, when invoked on a dataset it returns a modifiable transient type which is a copy of the dataset's data type. * Using a named data type in the call to H5Dcreate() causes the dataset object header to point to the named data type, but using a transient type causes the type to be copied into the dataset's object header. * The data type returned from H5Dget_type() is a named data type or a read-only transient data type depending on whether the dataset points to a named data type. The old behavior, to return a modifiable transient type, is accomplished by overloading H5Tcopy() to operate on datasets (see above). * H5Tshare(), H5Tunshare(), and H5Tis_shared() have been removed from the API. The following features were *not* implemented because they need more discussion: * A named data type can be opened by applying H5Topen() to a dataset in which case the data type is the data type of the dataset (or the data type to which the dataset points if the dataset has a shared data type). * A named data type can have attributes like groups or datasets. * The members of a compound data type can point to named data types. ./src/h5ls.c Reports `Data type' for named data type objects in the file.

To make a new file grab the BlankForm and modify it. By default, debugging is turned on for most packages. Within a package one can use `#ifdef H5AC_DEBUG' to wrap debugging code. Other options are: --enable-debug --enable-debug=yes The default, most but not all packages. --disable-debug --enable-debug=no --enable-debug=none The symbol NDEBUG is defined and none of the package debug symbols. --enable-debug=all Debugging is turned on for all packages. This might produce lots of output. --enable-debug=g,d Debugging is turned on for H5G and H5D. A compile mode is also now supported --enable-production --enable-production=yes The library is compiled with optimizations turned on. The compiler flags are augmented by adding PROD_CFLAGS and PROD_CPPFLAGS which are defined in the site config file. --disable-production --enable-production=no The default. The library is compiled for development by including DEBUG_CFLAGS and DEBUG_CPPFLAGS defined in the site config file. This is usually just `-g'. --enable-production=profile --enable-production=pg Builds a library for profiling by including the flags from PROFILE_CFLAGS and PROFILE_CPPFLAGS defined in the site config file. This is usullay just `-pg' but it could include optimization flags as well depending on the type of profile one wants. In summary, configure by saying `./configure' and you'll get a development version of the library. Configure by saying `./configure --enable-production --disable-debug' and you'll get a production version with no debugging code.

---------------------- ./html/Datasets.html Removed some archaic comments about data spaces. Fixed example code. ./MANIFEST ./html/H5.format.html ./src/H5O.c ./src/H5Oprivate.h ./src/H5Ocstore.c [DELETED] ./src/H5Oistore.c [DELETED] ./src/H5Olayout.c [NEW] ./src/Makefile.in ./test/istore.c Replaced H5O_CSTORE and H5O_ISTORE messages with a more general H5O_LAYOUT message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h A little more work on the pipeline. Access to the file data is through the new H5F_arr_read() and H5F_arr_write() which do I/O on hyperslabs of byte arrays and don't depend on data layout. This should simplify the I/O pipeline quite a bit. I also added another argument to H5Dread() and H5Dwrite() to describe the hyerslab of the file array on which I/O is occuring. We discussed this at last week's meeting. ./src/H5Farray.c [NEW] Added functions that sit on top of H5F_block_read() and H5F_istore_read() and implement a common set of functions between all layouts. This means I/O of hyperslabs of byte-arrays in the file to arrays of bytes in memory. When operating on arrays of elements (>1byte) then we just add another dimension. That is, a 10x20 array of int32 becomes a 10x20x4 array of bytes. [This is the area I'll be working on most of next week to implement partial I/O for contiguous data and to improve performance for chunked data.] ./src/H5Fistore.c ./src/H5Fprivate.h Replaced the H5F_istore_t data type with the layout message H5O_layout_t which looks almost the same. Eventually I'd like to rename `istore' to `chunked' everywhere and use `istore' for 1-d storage where the chunks are all different sizes like in the small object heap where each object is a chunk. ./src/H5V.c Changed ISTORE to LAYOUT in one place. ./test/dsets.c Fixed for extra argument to H5Dread() and H5Dwrite().
