[svn-r17] ./src/H5AC.c Renamed H5AC_find() to H5AC_find_f() which is invoked from the H5AC_find() macro. Changed HASH() to H5AC_HASH(). ./src/H5ACprivate.h Increased the number of cache slots from 1033 to 10330 to see how it affects performance. This should probably be changeable on a per-file basis. ./src/H5B.c Fixed some bugs now that symbol tables are actually using the stuff. Improved debugging a little. Fixed uninitialized memory appearing in the file. ./src/H5D.c Changed a FUNC_ENTER() argument from H5Dset_info to H5Dwrite. ./src/H5F.c Plugged a memory leak in H5F_dest(). ./src/H5G.c ./src/H5Gprivate.h Many of these functions take a symbol table entry which describes the symbol table rather than just the symbol table address. Moved some functions to make room for the ones that understand directory names: H5G_new() -> H5G_stab_new() H5G_find() -> H5G_stab_find() H5G_modify() -> H5G_stab_modify() H5G_insert() -> H5G_stab_insert() H5G_list() -> H5G_stab_list() ./src/H5Gnode.c Added more assertions. Zero new memory so junk doesn't appear in the data file. This is a problem when one tries to declassify a classified data file. H5G_node_debug() can take an extra argument which is the address of the heap for the symbol table. If supplied, the symbol names are printed along with the heap offsets. ./src/H5H.c ./src/H5Hprivate.h Fixed a bug with the free blocks by forcing things to align on even boundaries. It's still possible to lose heap memory if the hole is smaller than the free list header. The alternative is to align heap objects on 12 or 20 byte boundaries, but this tends to waste to much space. Zero new memory like with H5Gnode.c. Fixed a "mispeling" of NDEBUG. ./src/H5Ocont.c ./src/H5Onull.c Added the pablo mask defn. ./src/H5Ostab.c Added the pablo mask defn. Fixed a read from uninitialized memory. ./src/H5Oprivate.h Tuned some parameters to see how they affect performance. ./src/debug.c An optional third argument can be supplied which is the address of a heap to use to display names in a symbol table. ./src/hdf5pabl.h Changed `int' to `intn'.

* Purpose: Symbol table functions. The functions that
* begin with `H5G_stab_' don't understand the
* directory hierarchy; they operate on a single
* symbol table at a time.
*
* The functions that begin with `H5G_node_' operate
* on the leaf nodes of a symbol table B-tree. They
* should be defined in the H5Gnode.c file.
*
* The remaining functions know about the directory
* hierarchy.

[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

[svn-r25] ./src/H5AC.c We sort the cache before a complete flush because it might be more efficient to write things back to disk in order of increasing address.

This simplifies symbol table entry caching for the directory since the cached value never changes now. ./src/H5Gnode.c ./src/H5Gprivate.h Fine tuned the B-tree K values for symbol tables assuming an average number of symbols is about 100 per directory.

If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

* Function: H5G_mkroot
*
* Purpose: Creates the root directory if it doesn't exist; otherwise
[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

* nothing happens. If the root symbol table entry previously
* pointed to something other than a directory, then that object
* is made a member of the root directory and is given a name

[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

* A root directory is created implicitly by this function
* when necessary. Calling this function with the name "/"
* (or any equivalent name) will result in an H5E_EXISTS

[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

[svn-r44] ./src/H5D.c I commented out a bunch of code in H5D_flush() so I could compile and link the test cases. If you commit your changes to that file, whatever they may be, I'll change H5D_flush() to use the new directory functions described below... ./src/H5G.c H5G_namei() ----------- Understands files without directories. The root object (directory or not) can be found by asking for `/' (or any equivalent absolute or relative name like `/.//.///' or `.//.///' (if the cwd is the root)) or by name like `/foo' (or any other equivalent absolute or relative name) if the object has a name message with the value `foo'. This function is used by most of the other H5G functions so they now understand directory-less files too. H5G_new() --------- Creates the root directory implicitly if it doesn't already exist, moving any previous non-directory root object into the new root directory before creating the requested directory within the root. The creation of the root directory happens first, regardless of whether the requested directory creation succeeds. Once the root directory is created it never disappears even if the file later has only one object. This "feature" can be used to force a file to have a root directory by saying something like: H5G_new (..., "/", ...); H5ECLEAR; /*we don't care about the H5E_EXISTS failure*/ The H5G_new() in the previous example fails because the root directory is created implicitly before we attempt to create the requested "/" directory. H5G_find() ---------- Understands files without directories. If there is no root object then this function is guaranteed to fail even if the request is for `/'. As mentioned for H5G_namei(), the root object can be retrieved with `/' or `/foo' (or equivalent absolute or relative names). H5G_insert() ------------ Understands files without directories and attempts to create such files when there is only one object. The root symbol table is created implicitly when necessary. A root object can be given a name message by the caller and then inserted with the name `/' or it can be inserted with the name `/foo' in which case H5G_insert() will set the name message to `foo'. H5G_modify() ------------ Understands files without directories. ./src/H5Fprivate.h Removed the root_type field from hdf5_file_t. ./src/H5Fprivate.h ./src/H5F.c Removed H5F_root_type() ./src/H5Fpublic.h Removed H5F_root_symtype_t. ./src/H5Oprivate.h ./src/H5O.c Added H5O_remove() which is currently a no-op.

* Function: H5G_find
1997-07-31 05:17:56 +08:00
*
* Purpose: Finds an object with the specified NAME in file F. If
* the name is relative then it is interpretted relative
* to CWD, a symbol table entry for a symbol table. On
* successful return, DIR_ENT (if non-null) will be
* initialized with the symbol table information for the
* directory in which the object appears (or all zero if
* the returned object is the root object) and ENT will
* be initialized with the symbol table entry for the
* object (ENT is optional when the caller is interested
* only in the existence of the object).
1997-07-31 05:17:56 +08:00
*
* This function will fail if the root object is
* requested and there is none.
1997-07-31 05:17:56 +08:00
*
* Errors:
* DIRECTORY NOTFOUND Object not found.
*
* Return: Success: SUCCEED with DIR_ENT and ENT initialized. ENT
* is intended for immediate read-only access.
* If the object that ENT refers to is open
* through the ENT entry (see H5G_open()) then
* the returned ENT will contain the latest
* information. However, subsequent changes to
* the symbol table entry will not be reflected
* in ENT since it is a copy of the symbol table.

Use ./src/H5Ostab.c as a model for implementing other messages. ./src/Makefile ./src/test/Makefile Added new files ./src/debug.c Added debugging calls for object headers. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/H5MF.c Changed my e-mail address. Improved error handling. ./src/H5Eprivate.h ./src/H5Eproto.h Added more error symbols ./src/H5F.c Changed my e-mail address. Used macros for sizeof offsets and lengths. Added the interface initialization function to H5F_block_read() and H5F_block_write(). Updated H5F_debug() ./src/H5Fprivate.h Got rid of H5F_symbol_table_size(). Use H5G_SIZEOF_ENTRY() instead.
