zlib Error Codes

This topic describes only module-specific error codes. For details about universal error codes, see Universal Error Codes.

900001 Invalid Source File

Error Message

The input source file is invalid.

Description

This error code is reported when the source file passed in the compressFile() or decompressFile() API is invalid.

Possible Causes

When the compressFile() API is called, the file to compress does not exist. When the decompressFile() API is called, the file to decompress does not exist.

Solution

  1. Make sure the source file exists.
  2. Ensure that the source file is in ZIP format.
  3. Make sure the path of the source file exists and the path is the correct sandbox path.

900002 Invalid Destination File

Error Message

The input destination file is invalid.

Description

This error code is reported when the destination file passed in the compressFile() or decompressFile() API is invalid.

Possible Causes

  1. When the compressFile() API is called, the passed destination file path is invalid, for example, a non-exist sandbox path.
  2. When the decompressFile() API is called, the destination folder does not exist.

Solution

  1. Check whether the destination file path is correct. If not, enter the correct sandbox path.
  2. Check whether the destination folder exists. If not, create the folder.

900003 Source File in Incorrect Format or Damaged

Error Message

The input source file is not in ZIP format or is damaged.

Description

This error code is reported when the format of the source file is incorrect or the source file is damaged when the decompressFile API is called.

Possible Causes

  1. When the decompressFile API is called, the format of the source file is incorrect.
  2. When the decompressFile API is called, the source file is incomplete or damaged.

Solution

  1. Check whether the source file is in ZIP format.
  2. Check whether the source file is complete. If the file is downloaded from the network, ensure that the file download is complete before calling the decompressFile API.

17800002 Incorrect File or Access Mode

Error Message

No such file or access mode error.

Description

This error code is reported when the input file path, file descriptor, or file access mode is incorrect when the gzopen or gzdopen API is called.

Possible Causes

  1. When the gzopen API is called, the input file path or file access mode is incorrect.
  2. When the gzdopen API is called, the input file descriptor or file access mode is incorrect.

Solution

  1. Check whether the .gz file path or file descriptor is correct. If a .gz file is created, ensure that the file access is in compression mode (such as w or wb).
  2. Check whether the file access mode is w, wb, r, rb, a, and ab.

17800004 Compressed or Decompressed Flow Error

Error Message

Compression or decompression stream error, which may be caused by an initialization error in the zlib stream structure or a modified structure.

Description

This error code is reported when an error occurs in compression or decompression stream when the deflate or inflate API is called.

Possible Causes

  1. When the deflate or inflate API is called, the deflateInit or inflateInit API is not used to initialize the compression or decompression stream.
  2. When the gzsetparams, gzclose, or gzflush API is called, the input refresh mode is incorrect. When the API for opening a .gz file is called, the input file access mode is incorrect.

Solution

  1. Before calling the deflate or inflate API, use the deflateInit or inflateInit API to initialize the compression or decompression stream.
  2. Check whether the API for opening the .gz file is not called or fails to be called.
  3. Check whether the input access mode matches the API when the API for opening the .gz file is called. For example, gzprintf is a compression API. When the API for opening a .gz file is called, the input access mode must be the compression mode (such as w or wb).
  4. Check whether the input enum parameter is correct.

17800005 Incorrect Input Data

Error Message

The input data is incorrect. For example, the data does not conform to the zlib compression format, the compressed data is corrupted, or the data is not compressed.

Description

This error code is reported when the input data is incorrect when the uncompress or uncompress2 API is called.

Possible Causes

When the uncompress or uncompress2 API is called, the compress API is not used for compression.

Solution

Use the compress API to compress the file before using the uncompress2 or uncompress API to decompress the file.

17800006 Memory Allocation Failure

Error Message

Memory allocation failed.

Description

This error code is reported when the memory allocation fails when the gzclose or gzclosew API is called.

Possible Causes

The gzsetparams API is called before calling the gzclose or gzclosew API. As a result, an incorrect compression level or compression strategy is passed in.

Solution

Check whether the gzsetparams API is called and pass in the correct compression level and compression strategy.

17800007 Incorrect Input Buffer

Error Message

The input buffer is incorrect, and the output buffer is too small to accommodate the compressed or decompressed data.

Description

This error code is reported when the input buffer is incorrect when the compress, compress2, uncompress, or uncompress2 API is called.

Possible Causes

  1. When the uncompress or uncompress2 API is called, the input buffer size is greater than the output buffer size after decompression.
  2. When the compress or compress2 API is called, the input buffer size is greater than the output buffer size after compression.
  3. When the compress, compress2, uncompress, or uncompress2 API is called, the input buffer size is 0.

Solution

Increase the size of the corresponding buffer.

17800009 Internal Structure Error

Error Message

Internal structure error.

Description

This error code is reported when the input parameter is incorrect when the gzputc, gzwrite, or gzread API is called, or when the input file access mode is incorrect when the API for opening the .gz file is called.

Possible Causes

  1. The API for opening the .gz file is not called or fails to be called.
  2. When the API for opening the .gz file is called, the input file access mode is incorrect.
  3. When the gzwrite API is called, the length of the input uncompressed byte is 0.
  4. When the gzfwrite or gzfread API is called, the size or number of input data blocks is 0.
  5. When the gzprintf API is called, the input format descriptor and plain text are empty strings.
  6. When the gzgets API is called, the input ArrayBuffer is empty.
  7. When the gzgetc API is called, the .gz file is empty.

Solution

  1. Check whether the API for opening the .gz file is not called or fails to be called.
  2. Check whether the input access mode matches the API when the API for opening the .gz file is called. For example, gzgetc is a decompression API, so the input access mode should be decompression mode (such r or rb).
  3. Check whether the input parameter is correct.
