+ * ICU 56: New in formatVersion 3 compared with 2: -------------
+ *
+ * Resource bundles can optionally use shared string-v2 values
+ * stored in the pool bundle.
+ * If so, then the indexes[] contain two new values
+ * in previously-unused bits of existing indexes[] slots:
+ * - poolStringIndexLimit:
+ * String-v2 offsets (in 32-bit Resource words) below this limit
+ * point to pool bundle string-v2 values.
+ * - poolStringIndex16Limit:
+ * Resource16 string-v2 offsets below this limit
+ * point to pool bundle string-v2 values.
+ * Guarantee: poolStringIndex16Limit <= poolStringIndexLimit
+ *
+ * The local bundle's poolStringIndexLimit is greater than
+ * any pool bundle string index used in the local bundle.
+ * The poolStringIndexLimit should not be greater than
+ * the maximum possible pool bundle string index.
+ *
+ * The maximum possible pool bundle string index is the index to the last non-NUL
+ * pool string character, due to suffix sharing.
+ *
+ * In the pool bundle, there is no structure that lists the strings.
+ * (The root resource is an empty Table.)
+ * If the strings need to be enumerated (as genrb --usePoolBundle does),
+ * then iterate through the pool bundle's 16-bit-units array from the beginning.
+ * Stop at the end of the array, or when an explicit or implicit string length
+ * would lead beyond the end of the array,
+ * or when an apparent string is not NUL-terminated.
+ * (Future genrb version might terminate the strings with
+ * what looks like a large explicit string length.)
+ *
+ * ICU 4.4: New in formatVersion 2 compared with 1.3: -------------
+ *
+ * Three new resource types -- String-v2, Table16 and Array16 -- have their
+ * values stored in a new array of 16-bit units between the table key strings
+ * and the start of the other resources.
+ *
+ * genrb eliminates duplicates among Unicode string-v2 values.
+ * Multiple Unicode strings may use the same offset and string data,
+ * or a short string may point to the suffix of a longer string. ("Suffix sharing")
+ * For example, one string "abc" may be reused for another string "bc" by pointing
+ * to the second character. (Short strings-v2 are NUL-terminated
+ * and not preceded by an explicit length value.)
+ *
+ * It is allowed for all resource types to share values.
+ * The swapper code (ures_swap()) has been modified so that it swaps each item
+ * exactly once.
+ *
+ * A resource bundle may use a special pool bundle. Some or all of the table key strings
+ * of the using-bundle are omitted, and the key string offsets for such key strings refer
+ * to offsets in the pool bundle.
+ * The using-bundle's and the pool-bundle's indexes[URES_INDEX_POOL_CHECKSUM] values
+ * must match.
+ * Two bits in indexes[URES_INDEX_ATTRIBUTES] indicate whether a resource bundle
+ * is or uses a pool bundle.
+ *
+ * Table key strings must be compared in ASCII order, even if they are not
+ * stored in ASCII.
+ *
+ * New in formatVersion 1.3 compared with 1.2: -------------
+ *
+ * genrb eliminates duplicates among key strings.
+ * Multiple table items may share one key string, or one item may point
+ * to the suffix of another's key string. ("Suffix sharing")
+ * For example, one key "abc" may be reused for another key "bc" by pointing
+ * to the second character. (Key strings are NUL-terminated.)
+ *
+ * -------------
*
* An ICU4C resource bundle file (.res) is a binary, memory-mappable file
* with nested, hierarchical data structures.
* currently, the root item must be a table or table32 resource item
* int32_t indexes[indexes[0]]; -- array of indexes for friendly
* reading and swapping; see URES_INDEX_* above
- * new in formatVersion 1.1
+ * new in formatVersion 1.1 (ICU 2.8)
* char keys[]; -- characters for key strings
* (formatVersion 1.0: up to 65k of characters; 1.1: <2G)
* (minus the space for root and indexes[]),
* which consist of invariant characters (ASCII/EBCDIC) and are NUL-terminated;
* padded to multiple of 4 bytes for 4-alignment of the following data
+ * uint16_t 16BitUnits[]; -- resources that are stored entirely as sequences of 16-bit units
+ * (new in formatVersion 2/ICU 4.4)
+ * data is indexed by the offset values in 16-bit resource types,
+ * with offset 0 pointing to the beginning of this array;
+ * there is a 0 at offset 0, for empty resources;
+ * padded to multiple of 4 bytes for 4-alignment of the following data
* data; -- data directly and indirectly indexed by the root item;
* the structure is determined by walking the tree
*
* Leaves of the tree may be stored first or last or anywhere in between,
* and it is in theory possible to have unreferenced holes in the file.
*
+ * 16-bit-unit values:
+ * Starting with formatVersion 2/ICU 4.4, some resources are stored in a special
+ * array of 16-bit units. Each resource value is a sequence of 16-bit units,
+ * with no per-resource padding to a 4-byte boundary.
+ * 16-bit container types (Table16 and Array16) contain Resource16 values
+ * which are offsets to String-v2 resources in the same 16-bit-units array.
+ *
* Direct values:
* - Empty Unicode strings have an offset value of 0 in the Resource handle itself.
+ * - Starting with formatVersion 2/ICU 4.4, an offset value of 0 for
+ * _any_ resource type indicates an empty value.
* - Integer values are 28-bit values stored in the Resource handle itself;
* the interpretation of unsigned vs. signed integers is up to the application.
*
* To get byte offsets, the offset is multiplied by 4 (or shifted left by 2 bits).
* All resource item values are 4-aligned.
*
+ * New in formatVersion 2/ICU 4.4: Some types use offsets into the 16-bit-units array,
+ * indexing 16-bit units in that array.
+ *
* The structures (memory layouts) for the values for each item type are listed
- * in the table above.
+ * in the table below.
*
* Nested, hierarchical structures: -------------
*
- * Table items contain key-value pairs where the keys are 16-bit offsets to char * key strings.
- * Key string offsets are also relative to the start of the resource data (of the root handle),
- * i.e., the first string has an offset of 4 (after the 4-byte root handle).
+ * Table items contain key-value pairs where the keys are offsets to char * key strings.
+ * The values of these pairs are either Resource handles or
+ * offsets into the 16-bit-units array, depending on the table type.
+ *
+ * Array items are simple vectors of Resource handles,
+ * or of offsets into the 16-bit-units array, depending on the array type.
+ *
+ * Table key string offsets: -------
*
- * The values of these pairs are Resource handles.
+ * Key string offsets are relative to the start of the resource data (of the root handle),
+ * i.e., the first string has an offset of 4+sizeof(indexes).
+ * (After the 4-byte root handle and after the indexes array.)
*
- * Array items are simple vectors of Resource handles.
+ * If the resource bundle uses a pool bundle, then some key strings are stored
+ * in the pool bundle rather than in the local bundle itself.
+ * - In a Table or Table16, the 16-bit key string offset is local if it is
+ * less than indexes[URES_INDEX_KEYS_TOP]<<2.
+ * Otherwise, subtract indexes[URES_INDEX_KEYS_TOP]<<2 to get the offset into
+ * the pool bundle key strings.
+ * - In a Table32, the 32-bit key string offset is local if it is non-negative.
+ * Otherwise, reset bit 31 to get the pool key string offset.
+ *
+ * Unlike the local offset, the pool key offset is relative to
+ * the start of the key strings, not to the start of the bundle.
*
* An alias item is special (and new in ICU 2.4): --------------
*
* Some resource values are stored directly in the offset field of the Resource itself.
* See UResType in unicode/ures.h for enumeration constants for Resource types.
*
+ * Some resources have their values stored as sequences of 16-bit units,
+ * at 2-byte offsets from the start of a contiguous 16-bit-unit array between
+ * the table key strings and the other resources. (new in formatVersion 2/ICU 4.4)
+ * At offset 0 of that array is a 16-bit zero value for empty 16-bit resources.
+ *
+ * Resource16 values in Table16 and Array16 are 16-bit offsets to String-v2
+ * resources, with the offsets relative to the start of the 16-bit-units array.
+ * Starting with formatVersion 3/ICU 56, if offset<poolStringIndex16Limit
+ * then use the pool bundle's 16-bit-units array,
+ * otherwise subtract that limit and use the local 16-bit-units array.
+ *
* Type Name Memory layout of values
* (in parentheses: scalar, non-offset values)
*
* 0 Unicode String: int32_t length, UChar[length], (UChar)0, (padding)
* or (empty string ("") if offset==0)
* 1 Binary: int32_t length, uint8_t[length], (padding)
- * - this value should be 32-aligned -
+ * - the start of the bytes is 16-aligned -
* 2 Table: uint16_t count, uint16_t keyStringOffsets[count], (uint16_t padding), Resource[count]
* 3 Alias: (physically same value layout as string, new in ICU 2.4)
* 4 Table32: int32_t count, int32_t keyStringOffsets[count], Resource[count]
* (new in formatVersion 1.1/ICU 2.8)
+ * 5 Table16: uint16_t count, uint16_t keyStringOffsets[count], Resource16[count]
+ * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
+ * 6 Unicode String-v2:UChar[length], (UChar)0; length determined by the first UChar:
+ * - if first is not a trail surrogate, then the length is implicit
+ * and u_strlen() needs to be called
+ * - if first<0xdfef then length=first&0x3ff (and skip first)
+ * - if first<0xdfff then length=((first-0xdfef)<<16) | second UChar
+ * - if first==0xdfff then length=((second UChar)<<16) | third UChar
+ * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
+ *
+ * Starting with formatVersion 3/ICU 56, if offset<poolStringIndexLimit
+ * then use the pool bundle's 16-bit-units array,
+ * otherwise subtract that limit and use the local 16-bit-units array.
+ * (Note different limits for Resource16 vs. Resource.)
*
* 7 Integer: (28-bit offset is integer value)
* 8 Array: int32_t count, Resource[count]
- *
+ * 9 Array16: uint16_t count, Resource16[count]
+ * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
* 14 Integer Vector: int32_t length, int32_t[length]
* 15 Reserved: This value denotes special purpose resources and is for internal use.
*
* Note that there are 3 types with data vector values:
* - Vectors of 8-bit bytes stored as type Binary.
- * - Vectors of 16-bit words stored as type Unicode String
+ * - Vectors of 16-bit words stored as type Unicode String or Unicode String-v2
* (no value restrictions, all values 0..ffff allowed!).
* - Vectors of 32-bit words stored as type Integer Vector.
