/* Function calling conventions.
|
||||
* =============================
|
||||
* Normally it is not necessary to specify to the compiler how to call
|
||||
* a function - it just does it - however on x86 systems derived from
|
||||
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
|
||||
* and some others) there are multiple ways to call a function and the
|
||||
* default can be changed on the compiler command line. For this reason
|
||||
* libpng specifies the calling convention of every exported function and
|
||||
* every function called via a user supplied function pointer. This is
|
||||
* done in this file by defining the following macros:
|
||||
*
|
||||
* PNGAPI Calling convention for exported functions.
|
||||
* PNGCBAPI Calling convention for user provided (callback) functions.
|
||||
* PNGCAPI Calling convention used by the ANSI-C library (required
|
||||
* for longjmp callbacks and sometimes used internally to
|
||||
* specify the calling convention for zlib).
|
||||
*
|
||||
* These macros should never be overridden. If it is necessary to
|
||||
* change calling convention in a private build this can be done
|
||||
* by setting PNG_API_RULE (which defaults to 0) to one of the values
|
||||
* below to select the correct 'API' variants.
|
||||
*
|
||||
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
|
||||
* This is correct in every known environment.
|
||||
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
|
||||
* the 'C' calling convention (from PNGCAPI) for
|
||||
* callbacks (PNGCBAPI). This is no longer required
|
||||
* in any known environment - if it has to be used
|
||||
* please post an explanation of the problem to the
|
||||
* libpng mailing list.
|
||||
*
|
||||
* These cases only differ if the operating system does not use the C
|
||||
* calling convention, at present this just means the above cases
|
||||
* (x86 DOS/Windows systems) and, even then, this does not apply to
|
||||
* Cygwin running on those systems.
|
||||
*
|
||||
* Note that the value must be defined in pnglibconf.h so that what
|
||||
* the application uses to call the library matches the conventions
|
||||
* set when building the library.
|
||||
*/
|
||||
|
||||
/* Symbol export
|
||||
* =============
|
||||
* When building a shared library it is almost always necessary to tell
|
||||
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
|
||||
* is used to mark the symbols. On some systems these symbols can be
|
||||
* extracted at link time and need no special processing by the compiler,
|
||||
* on other systems the symbols are flagged by the compiler and just
|
||||
* the declaration requires a special tag applied (unfortunately) in a
|
||||
* compiler dependent way. Some systems can do either.
|
||||
*
|
||||
* A small number of older systems also require a symbol from a DLL to
|
||||
* be flagged to the program that calls it. This is a problem because
|
||||
* we do not know in the header file included by application code that
|
||||
* the symbol will come from a shared library, as opposed to a statically
|
||||
* linked one. For this reason the application must tell us by setting
|
||||
* the magic flag PNG_USE_DLL to turn on the special processing before
|
||||
* it includes png.h.
|
||||
*
|
||||
* Four additional macros are used to make this happen:
|
||||
*
|
||||
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
|
||||
* the build or imported if PNG_USE_DLL is set - compiler
|
||||
* and system specific.
|
||||
*
|
||||
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
|
||||
* 'type', compiler specific.
|
||||
*
|
||||
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
|
||||
* make a symbol exported from the DLL. Not used in the
|
||||
* public header files; see pngpriv.h for how it is used
|
||||
* in the libpng build.
|
||||
*
|
||||
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
|
||||
* from a DLL - used to define PNG_IMPEXP when
|
||||
* PNG_USE_DLL is set.
|
||||
*/
|
||||
|
||||
/* System specific discovery.
|
||||
* ==========================
|
||||
* This code is used at build time to find PNG_IMPEXP, the API settings
|
||||
* and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
|
||||
* import processing is possible. On Windows systems it also sets

* Zstd dictionary builder
|
||||
*
|
||||
* FAQ
|
||||
* ===
|
||||
* Why should I use a dictionary?
|
||||
* ------------------------------
|
||||
*
|
||||
* Zstd can use dictionaries to improve compression ratio of small data.
|
||||
* Traditionally small files don't compress well because there is very little
|
||||
* repetition in a single sample, since it is small. But, if you are compressing
|
||||
* many similar files, like a bunch of JSON records that share the same
|
||||
* structure, you can train a dictionary on ahead of time on some samples of
|
||||
* these files. Then, zstd can use the dictionary to find repetitions that are
|
||||
* present across samples. This can vastly improve compression ratio.
|
||||
*
|
||||
* When is a dictionary useful?
|
||||
* ----------------------------
|
||||
*
|
||||
* Dictionaries are useful when compressing many small files that are similar.
|
||||
* The larger a file is, the less benefit a dictionary will have. Generally,
|
||||
* we don't expect dictionary compression to be effective past 100KB. And the
|
||||
* smaller a file is, the more we would expect the dictionary to help.
|
||||
*
|
||||
* How do I use a dictionary?
|
||||
* --------------------------
|
||||
*
|
||||
* Simply pass the dictionary to the zstd compressor with
|
||||
* `ZSTD_CCtx_loadDictionary()`. The same dictionary must then be passed to
|
||||
* the decompressor, using `ZSTD_DCtx_loadDictionary()`. There are other
|
||||
* more advanced functions that allow selecting some options, see zstd.h for
|
||||
* complete documentation.
|
||||
*
|
||||
* What is a zstd dictionary?
|
||||
* --------------------------
|
||||
*
|
||||
* A zstd dictionary has two pieces: Its header, and its content. The header
|
||||
* contains a magic number, the dictionary ID, and entropy tables. These
|
||||
* entropy tables allow zstd to save on header costs in the compressed file,
|
||||
* which really matters for small data. The content is just bytes, which are
|
||||
* repeated content that is common across many samples.
|
||||
*
|
||||
* What is a raw content dictionary?
|
||||
* ---------------------------------
|
||||
*
|
||||
* A raw content dictionary is just bytes. It doesn't have a zstd dictionary
|
||||
* header, a dictionary ID, or entropy tables. Any buffer is a valid raw
|
||||
* content dictionary.
|
||||
*
|
||||
* How do I train a dictionary?
|
||||
* ----------------------------
|
||||
*
|
||||
* Gather samples from your use case. These samples should be similar to each
|
||||
* other. If you have several use cases, you could try to train one dictionary
|
||||
* per use case.
|
||||
*
|
||||
* Pass those samples to `ZDICT_trainFromBuffer()` and that will train your
|
||||
* dictionary. There are a few advanced versions of this function, but this
|
||||
* is a great starting point. If you want to further tune your dictionary
|
||||
* you could try `ZDICT_optimizeTrainFromBuffer_cover()`. If that is too slow
|
||||
* you can try `ZDICT_optimizeTrainFromBuffer_fastCover()`.
|
||||
*
|
||||
* If the dictionary training function fails, that is likely because you
|
||||
* either passed too few samples, or a dictionary would not be effective
|
||||
* for your data. Look at the messages that the dictionary trainer printed,
|
||||
* if it doesn't say too few samples, then a dictionary would not be effective.
|
||||
*
|
||||
* How large should my dictionary be?
|
||||
* ----------------------------------
|
||||
*
|
||||
* A reasonable dictionary size, the `dictBufferCapacity`, is about 100KB.
|
||||
* The zstd CLI defaults to a 110KB dictionary. You likely don't need a
|
||||
* dictionary larger than that. But, most use cases can get away with a
|
||||
* smaller dictionary. The advanced dictionary builders can automatically
|
||||
* shrink the dictionary for you, and select the smallest size that doesn't
|
||||
* hurt compression ratio too much. See the `shrinkDict` parameter.
|
||||
* A smaller dictionary can save memory, and potentially speed up
|
||||
* compression.
|
||||
*
|
||||
* How many samples should I provide to the dictionary builder?
|
||||
* ------------------------------------------------------------
|
||||
*
|
||||
* We generally recommend passing ~100x the size of the dictionary
|
||||
* in samples. A few thousand should suffice. Having too few samples
|
||||
* can hurt the dictionaries effectiveness. Having more samples will
|
||||
* only improve the dictionaries effectiveness. But having too many
|
||||
* samples can slow down the dictionary builder.
|
||||
*
|
||||
* How do I determine if a dictionary will be effective?
|
||||
* -----------------------------------------------------
|
||||
*
|
||||
* Simply train a dictionary and try it out. You can use zstd's built in
|
||||
* benchmarking tool to test the dictionary effectiveness.
|
||||
*
|
||||
* # Benchmark levels 1-3 without a dictionary
|
||||
* zstd -b1e3 -r /path/to/my/files
|
||||
* # Benchmark levels 1-3 with a dictionary
|
||||
* zstd -b1e3 -r /path/to/my/files -D /path/to/my/dictionary
|
||||
*
|
||||
* When should I retrain a dictionary?
|
||||
* -----------------------------------
|
||||
*
|
||||
* You should retrain a dictionary when its effectiveness drops. Dictionary
|
||||
* effectiveness drops as the data you are compressing changes. Generally, we do
|
||||
* expect dictionaries to "decay" over time, as your data changes, but the rate
|
||||
* at which they decay depends on your use case. Internally, we regularly
|
||||
* retrain dictionaries, and if the new dictionary performs significantly
|
||||
* better than the old dictionary, we will ship the new dictionary.
|
||||
*
|
||||
* I have a raw content dictionary, how do I turn it into a zstd dictionary?
|
||||
* -------------------------------------------------------------------------
|
||||
*
|
||||
* If you have a raw content dictionary, e.g. by manually constructing it, or
|
||||
* using a third-party dictionary builder, you can turn it into a zstd
|
||||
* dictionary by using `ZDICT_finalizeDictionary()`. You'll also have to
|
||||
* provide some samples of the data. It will add the zstd header to the
|
||||
* raw content, which contains a dictionary ID and entropy tables, which
|
||||
* will improve compression ratio, and allow zstd to write the dictionary ID
|
||||
* into the frame, if you so choose.
|
||||
*
|
||||
* Do I have to use zstd's dictionary builder?
|
||||
* -------------------------------------------
|
||||
*
|
||||
* No! You can construct dictionary content however you please, it is just
|
||||
* bytes. It will always be valid as a raw content dictionary. If you want
|
||||
* a zstd dictionary, which can improve compression ratio, use
|
||||
* `ZDICT_finalizeDictionary()`.
|
||||
*
|
||||
* What is the attack surface of a zstd dictionary?
|
||||
* ------------------------------------------------
|
||||
*
|
||||
* Zstd is heavily fuzz tested, including loading fuzzed dictionaries, so
|
||||
* zstd should never crash, or access out-of-bounds memory no matter what
|
||||
* the dictionary is. However, if an attacker can control the dictionary
|
||||
* during decompression, they can cause zstd to generate arbitrary bytes,
|
||||
* just like if they controlled the compressed data.

/* Function calling conventions.
|
||||
* =============================
|
||||
* Normally it is not necessary to specify to the compiler how to call
|
||||
* a function - it just does it - however on x86 systems derived from
|
||||
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
|
||||
* and some others) there are multiple ways to call a function and the
|
||||
* default can be changed on the compiler command line. For this reason
|
||||
* libpng specifies the calling convention of every exported function and
|
||||
* every function called via a user supplied function pointer. This is
|
||||
* done in this file by defining the following macros:
|
||||
*
|
||||
* PNGAPI Calling convention for exported functions.
|
||||
* PNGCBAPI Calling convention for user provided (callback) functions.
|
||||
* PNGCAPI Calling convention used by the ANSI-C library (required
|
||||
* for longjmp callbacks and sometimes used internally to
|
||||
* specify the calling convention for zlib).
|
||||
*
|
||||
* These macros should never be overridden. If it is necessary to
|
||||
* change calling convention in a private build this can be done
|
||||
* by setting PNG_API_RULE (which defaults to 0) to one of the values
|
||||
* below to select the correct 'API' variants.
|
||||
*
|
||||
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
|
||||
* This is correct in every known environment.
|
||||
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
|
||||
* the 'C' calling convention (from PNGCAPI) for
|
||||
* callbacks (PNGCBAPI). This is no longer required
|
||||
* in any known environment - if it has to be used
|
||||
* please post an explanation of the problem to the
|
||||
* libpng mailing list.
|
||||
*
|
||||
* These cases only differ if the operating system does not use the C
|
||||
* calling convention, at present this just means the above cases
|
||||
* (x86 DOS/Windows systems) and, even then, this does not apply to
|
||||
* Cygwin running on those systems.
|
||||
*
|
||||
* Note that the value must be defined in pnglibconf.h so that what
|
||||
* the application uses to call the library matches the conventions
|
||||
* set when building the library.
|
||||
*/
|
||||
|
||||
/* Symbol export
|
||||
* =============
|
||||
* When building a shared library it is almost always necessary to tell
|
||||
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
|
||||
* is used to mark the symbols. On some systems these symbols can be
|
||||
* extracted at link time and need no special processing by the compiler,
|
||||
* on other systems the symbols are flagged by the compiler and just
|
||||
* the declaration requires a special tag applied (unfortunately) in a
|
||||
* compiler dependent way. Some systems can do either.
|
||||
*
|
||||
* A small number of older systems also require a symbol from a DLL to
|
||||
* be flagged to the program that calls it. This is a problem because
|
||||
* we do not know in the header file included by application code that
|
||||
* the symbol will come from a shared library, as opposed to a statically
|
||||
* linked one. For this reason the application must tell us by setting
|
||||
* the magic flag PNG_USE_DLL to turn on the special processing before
|
||||
* it includes png.h.
|
||||
*
|
||||
* Four additional macros are used to make this happen:
|
||||
*
|
||||
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
|
||||
* the build or imported if PNG_USE_DLL is set - compiler
|
||||
* and system specific.
|
||||
*
|
||||
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
|
||||
* 'type', compiler specific.
|
||||
*
|
||||
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
|
||||
* make a symbol exported from the DLL. Not used in the
|
||||
* public header files; see pngpriv.h for how it is used
|
||||
* in the libpng build.
|
||||
*
|
||||
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
|
||||
* from a DLL - used to define PNG_IMPEXP when
|
||||
* PNG_USE_DLL is set.

* Zstd dictionary builder
|
||||
*
|
||||
* FAQ
|
||||
* ===
|
||||
* Why should I use a dictionary?
|
||||
* ------------------------------
|
||||
*
|
||||
* Zstd can use dictionaries to improve compression ratio of small data.
|
||||
* Traditionally small files don't compress well because there is very little
|
||||
* repetition in a single sample, since it is small. But, if you are compressing
|
||||
* many similar files, like a bunch of JSON records that share the same
|
||||
* structure, you can train a dictionary on ahead of time on some samples of
|
||||
* these files. Then, zstd can use the dictionary to find repetitions that are
|
||||
* present across samples. This can vastly improve compression ratio.
|
||||
*
|
||||
* When is a dictionary useful?
|
||||
* ----------------------------
|
||||
*
|
||||
* Dictionaries are useful when compressing many small files that are similar.
|
||||
* The larger a file is, the less benefit a dictionary will have. Generally,
|
||||
* we don't expect dictionary compression to be effective past 100KB. And the
|
||||
* smaller a file is, the more we would expect the dictionary to help.
|
||||
*
|
||||
* How do I use a dictionary?
|
||||
* --------------------------
|
||||
*
|
||||
* Simply pass the dictionary to the zstd compressor with
|
||||
* `ZSTD_CCtx_loadDictionary()`. The same dictionary must then be passed to
|
||||
* the decompressor, using `ZSTD_DCtx_loadDictionary()`. There are other
|
||||
* more advanced functions that allow selecting some options, see zstd.h for
|
||||
* complete documentation.
|
||||
*
|
||||
* What is a zstd dictionary?
|
||||
* --------------------------
|
||||
*
|
||||
* A zstd dictionary has two pieces: Its header, and its content. The header
|
||||
* contains a magic number, the dictionary ID, and entropy tables. These
|
||||
* entropy tables allow zstd to save on header costs in the compressed file,
|
||||
* which really matters for small data. The content is just bytes, which are
|
||||
* repeated content that is common across many samples.
|
||||
*
|
||||
* What is a raw content dictionary?
|
||||
* ---------------------------------
|
||||
*
|
||||
* A raw content dictionary is just bytes. It doesn't have a zstd dictionary
|
||||
* header, a dictionary ID, or entropy tables. Any buffer is a valid raw
|
||||
* content dictionary.
|
||||
*
|
||||
* How do I train a dictionary?
|
||||
* ----------------------------
|
||||
*
|
||||
* Gather samples from your use case. These samples should be similar to each
|
||||
* other. If you have several use cases, you could try to train one dictionary
|
||||
* per use case.
|
||||
*
|
||||
* Pass those samples to `ZDICT_trainFromBuffer()` and that will train your
|
||||
* dictionary. There are a few advanced versions of this function, but this
|
||||
* is a great starting point. If you want to further tune your dictionary
|
||||
* you could try `ZDICT_optimizeTrainFromBuffer_cover()`. If that is too slow
|
||||
* you can try `ZDICT_optimizeTrainFromBuffer_fastCover()`.
|
||||
*
|
||||
* If the dictionary training function fails, that is likely because you
|
||||
* either passed too few samples, or a dictionary would not be effective
|
||||
* for your data. Look at the messages that the dictionary trainer printed,
|
||||
* if it doesn't say too few samples, then a dictionary would not be effective.
|
||||
*
|
||||
* How large should my dictionary be?
|
||||
* ----------------------------------
|
||||
*
|
||||
* A reasonable dictionary size, the `dictBufferCapacity`, is about 100KB.
|
||||
* The zstd CLI defaults to a 110KB dictionary. You likely don't need a
|
||||
* dictionary larger than that. But, most use cases can get away with a
|
||||
* smaller dictionary. The advanced dictionary builders can automatically
|
||||
* shrink the dictionary for you, and select the smallest size that doesn't
|
||||
* hurt compression ratio too much. See the `shrinkDict` parameter.
|
||||
* A smaller dictionary can save memory, and potentially speed up
|
||||
* compression.
|
||||
*
|
||||
* How many samples should I provide to the dictionary builder?
|
||||
* ------------------------------------------------------------
|
||||
*
|
||||
* We generally recommend passing ~100x the size of the dictionary
|
||||
* in samples. A few thousand should suffice. Having too few samples
|
||||
* can hurt the dictionaries effectiveness. Having more samples will
|
||||
* only improve the dictionaries effectiveness. But having too many
|
||||
* samples can slow down the dictionary builder.
|
||||
*
|
||||
* How do I determine if a dictionary will be effective?
|
||||
* -----------------------------------------------------
|
||||
*
|
||||
* Simply train a dictionary and try it out. You can use zstd's built in
|
||||
* benchmarking tool to test the dictionary effectiveness.
|
||||
*
|
||||
* # Benchmark levels 1-3 without a dictionary
|
||||
* zstd -b1e3 -r /path/to/my/files
|
||||
* # Benchmark levels 1-3 with a dictionary
|
||||
* zstd -b1e3 -r /path/to/my/files -D /path/to/my/dictionary
|
||||
*
|
||||
* When should I retrain a dictionary?
|
||||
* -----------------------------------
|
||||
*
|
||||
* You should retrain a dictionary when its effectiveness drops. Dictionary
|
||||
* effectiveness drops as the data you are compressing changes. Generally, we do
|
||||
* expect dictionaries to "decay" over time, as your data changes, but the rate
|
||||
* at which they decay depends on your use case. Internally, we regularly
|
||||
* retrain dictionaries, and if the new dictionary performs significantly
|
||||
* better than the old dictionary, we will ship the new dictionary.
|
||||
*
|
||||
* I have a raw content dictionary, how do I turn it into a zstd dictionary?
|
||||
* -------------------------------------------------------------------------
|
||||
*
|
||||
* If you have a raw content dictionary, e.g. by manually constructing it, or
|
||||
* using a third-party dictionary builder, you can turn it into a zstd
|
||||
* dictionary by using `ZDICT_finalizeDictionary()`. You'll also have to
|
||||
* provide some samples of the data. It will add the zstd header to the
|
||||
* raw content, which contains a dictionary ID and entropy tables, which
|
||||
* will improve compression ratio, and allow zstd to write the dictionary ID
|
||||
* into the frame, if you so choose.
|
||||
*
|
||||
* Do I have to use zstd's dictionary builder?
|
||||
* -------------------------------------------
|
||||
*
|
||||
* No! You can construct dictionary content however you please, it is just
|
||||
* bytes. It will always be valid as a raw content dictionary. If you want
|
||||
* a zstd dictionary, which can improve compression ratio, use
|
||||
* `ZDICT_finalizeDictionary()`.
|
||||
*
|
||||
* What is the attack surface of a zstd dictionary?
|
||||
* ------------------------------------------------
|
||||
*
|
||||
* Zstd is heavily fuzz tested, including loading fuzzed dictionaries, so
|
||||
* zstd should never crash, or access out-of-bounds memory no matter what
|
||||
* the dictionary is. However, if an attacker can control the dictionary
|
||||
* during decompression, they can cause zstd to generate arbitrary bytes,
|
||||
* just like if they controlled the compressed data.
