// http://suitesparse.com See GraphBLAS/Doc/License.txt for license.
//------------------------------------------------------------------------------
// The eWise add of two matrices, C=A+B, C<M>=A+B, or C<!M>=A+B starts with
// this phase, which determines which vectors of C need to be computed.
// This phase is also used for GB_masker.
// On input, A and B are the two matrices being added, and M is the optional
// mask matrix (not complemented). The complemented mask is handed in GB_mask,
// not here.
// The A matrix can be sparse, hypersparse, slice, or hyperslice. The B matrix
// can only be sparse or hypersparse. See GB_Matrix_wait, which can pass in A
// as any of the four formats. In this case, no mask is present.
// On output, an integer (Cnvec) a boolean (Ch_to_Mh) and up to 3 arrays are
// returned, either NULL or of size Cnvec. Let n = A->vdim be the vector
// dimension of A, B, M and C.
// Ch: the list of vectors to compute. If not NULL, Ch [k] = j is the
// kth vector in C to compute, which will become the hyperlist C->h of C.
// Note that some of these vectors may turn out to be empty, because of
// the mask, or because the vector j appeared in A or B, but is empty.
// It is pruned at the end of GB_add_phase2. If Ch is NULL then it is an
// implicit list of size n, and Ch [k] == k for all k = 0:n-1. In this
// case, C will be a standard matrix, not hypersparse. Thus, the kth
// vector is j = (Ch == NULL) ? k : Ch [k].
// Ch is freed by GB_add if phase1 fails. phase2 either frees it or
// transplants it into C.
// Ch_is_Mh: true if the mask M is present, hypersparse, and not
// complemented, false otherwise. In this case Ch is a deep copy of Mh.
// Only GB_add uses this option; it is not used by GB_masker (Ch_is_Mh
// is always false for GB_masker). This is determined by passing in
// p_Ch_is_Mh as a NULL or non-NULL pointer.
// C_to_A: if A is hypersparse, then C_to_A [k] = kA if the kth vector, j
// = (Ch == NULL) ? k : Ch [k] appears in A, as j = Ah [kA]. If j does
// not appear in A, then C_to_A [k] = -1. If A is not hypersparse, then
// C_to_A is returned as NULL.
// C_to_B: if B is hypersparse, then C_to_B [k] = kB if the kth vector, j
// = (Ch == NULL) ? k : Ch [k] appears in B, as j = Bh [kB]. If j does
// not appear in B, then C_to_B [k] = -1. If B is not hypersparse, then
// C_to_B is returned as NULL.
// C_to_M: if M is hypersparse, and Ch_is_Mh is false, then C_to_M [k] =
// kM if the kth vector, j = (Ch == NULL) ? k : Ch [k] appears in M, as j
// = Mh [kM]. If j does not appear in M, then C_to_M [k] = -1. If M is

/* miniz.c v1.15 - public domain deflate/inflate, zlib-subset, ZIP
reading/writing/appending, PNG writing
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
http://www.ietf.org/rfc/rfc1951.txt
Most API's defined in miniz.c are optional. For example, to disable the
archive related functions just define
MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO
(see the list below for more macros).
* Change History
10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
release with Zip64 support (almost there!):
- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
(thanks kahmyong.moon@hp.com) which could cause locate files to not find
files. This bug
would only have occured in earlier versions if you explicitly used this
flag, OR if you used mz_zip_extract_archive_file_to_heap() or
mz_zip_add_mem_to_archive_file_in_place()
(which used this flag). If you can't switch to v1.15 but want to fix
this bug, just remove the uses of this flag from both helper funcs (and of
course don't use the flag).
- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
pUser_read_buf is not NULL and compressed size is > uncompressed size
- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
compressed data from directory entries, to account for weird zipfiles which
contain zero-size compressed data on dir entries.
Hopefully this fix won't cause any issues on weird zip archives,
because it assumes the low 16-bits of zip external attributes are DOS
attributes (which I believe they always are in practice).
- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
internal attributes, just the filename and external attributes
- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
- Added cmake support for Linux builds which builds all the examples,
tested with clang v3.3 and gcc v4.6.
- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
- Merged MZ_FORCEINLINE fix from hdeanclark
- Fix <time.h> include before config #ifdef, thanks emil.brink
- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
(super useful for OpenGL apps), and explicit control over the compression
level (so you can
set it to 1 for real-time compression).
- Merged in some compiler fixes from paulharris's github repro.
- Retested this build under Windows (VS 2010, including static analysis),
tcc 0.9.26, gcc v4.6 and clang v3.3.
- Added example6.c, which dumps an image of the mandelbrot set to a PNG
file.
- Modified example2 to help test the
MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
possible src file fclose() leak if alignment bytes+local header file write
faiiled
- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader():
Was pushing the wrong central dir header offset, appears harmless in this
release, but it became a problem in the zip64 branch
5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE,
#include <time.h> (thanks fermtect).
5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
re-ran a randomized regression test on ~500k files.
- Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
(static analysis) option and fixed all warnings (except for the silly
"Use of the comma-operator in a tested expression.." analysis warning,
which I purposely use to work around a MSVC compiler warning).
- Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
tested Linux executables. The codeblocks workspace is compatible with
Linux+Win32/x64.
- Added miniz_tester solution/project, which is a useful little app
derived from LZHAM's tester app that I use as part of the regression test.
- Ran miniz.c and tinfl.c through another series of regression testing on
~500,000 files and archives.
- Modified example5.c so it purposely disables a bunch of high-level
functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
MINIZ_NO_STDIO bug report.)
- Fix ftell() usage in examples so they exit with an error on files which
are too large (a limitation of the examples, not miniz itself).
4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple
minor level_and_flags issues in the archive API's.
level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce
Dawson <bruced@valvesoftware.com> for the feedback/bug report.
5/28/11 v1.11 - Added statement from unlicense.org
5/27/11 v1.10 - Substantial compressor optimizations:
- Level 1 is now ~4x faster than before. The L1 compressor's throughput
now varies between 70-110MB/sec. on a
- Core i7 (actual throughput varies depending on the type of data, and x64
vs. x86).
- Improved baseline L2-L9 compression perf. Also, greatly improved
compression perf. issues on some file types.
- Refactored the compression code for better readability and
maintainability.
- Added level 10 compression level (L10 has slightly better ratio than
level 9, but could have a potentially large
drop in throughput on some files).
5/15/11 v1.09 - Initial stable release.
* Low-level Deflate/Inflate implementation notes:
Compression: Use the "tdefl" API's. The compressor supports raw, static,
and dynamic blocks, lazy or
greedy parsing, match length filtering, RLE-only, and Huffman-only streams.
It performs and compresses
approximately as well as zlib.
Decompression: Use the "tinfl" API's. The entire decompressor is
implemented as a single function
coroutine: see tinfl_decompress(). It supports decompression into a 32KB
(or larger power of 2) wrapping buffer, or into a memory
block large enough to hold the entire file.
The low-level tdefl/tinfl API's do not make any use of dynamic memory
allocation.
* zlib-style API notes:
miniz.c implements a fairly large subset of zlib. There's enough
functionality present for it to be a drop-in
zlib replacement in many apps:
The z_stream struct, optional memory allocation callbacks
deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
inflateInit/inflateInit2/inflate/inflateEnd
compress, compress2, compressBound, uncompress
CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
routines.
Supports raw deflate streams or standard zlib streams with adler-32
checking.
Limitations:
The callback API's are not implemented yet. No support for gzip headers or
zlib static dictionaries.
I've tried to closely emulate zlib's various flavors of stream flushing
and return status codes, but
there are no guarantees that miniz.c pulls this off perfectly.
* PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
originally written by
Alex Evans. Supports 1-4 bytes/pixel images.
* ZIP archive API notes:
The ZIP archive API's where designed with simplicity and efficiency in
mind, with just enough abstraction to
get the job done with minimal fuss. There are simple API's to retrieve file
information, read files from
existing archives, create new archives, append new files to existing
archives, or clone archive data from
one archive to another. It supports archives located in memory or the heap,
on disk (using stdio.h),
or you can specify custom file read/write callbacks.
- Archive reading: Just call this function to read a single file from a
disk archive:
void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
char *pArchive_name,
size_t *pSize, mz_uint zip_flags);
For more complex cases, use the "mz_zip_reader" functions. Upon opening an
archive, the entire central
directory is located and read as-is into memory, and subsequent file access
only occurs when reading individual files.
- Archives file scanning: The simple way is to use this function to scan a
loaded archive for a specific file:
int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
const char *pComment, mz_uint flags);
The locate operation can optionally check file comments too, which (as one
example) can be used to identify
multiple versions of the same file in an archive. This function uses a
simple linear search through the central
directory, so it's not very fast.
Alternately, you can iterate through all the files in an archive (using
mz_zip_reader_get_num_files()) and
retrieve detailed info on each file by calling mz_zip_reader_file_stat().
- Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
immediately writes compressed file data
to disk and builds an exact image of the central directory in memory. The
central directory image is written
all at once at the end of the archive file when the archive is finalized.
The archive writer can optionally align each file's local header and file
data to any power of 2 alignment,
which can be useful when the archive will be read from optical media. Also,
the writer supports placing
arbitrary data blobs at the very beginning of ZIP archives. Archives
written using either feature are still
readable by any ZIP tool.
- Archive appending: The simple way to add a single file to an archive is
to call this function:
mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
const char *pArchive_name,
const void *pBuf, size_t buf_size, const void *pComment, mz_uint16
comment_size, mz_uint level_and_flags);
The archive will be created if it doesn't already exist, otherwise it'll be
appended to.
Note the appending is done in-place and is not an atomic operation, so if
something goes wrong
during the operation it's possible the archive could be left without a
central directory (although the local
file headers and file data will be fine, so the archive will be
recoverable).
For more complex archive modification scenarios:
1. The safest way is to use a mz_zip_reader to read the existing archive,
cloning only those bits you want to
preserve into a new archive using using the
mz_zip_writer_add_from_zip_reader() function (which compiles the
compressed file data as-is). When you're done, delete the old archive and
rename the newly written archive, and
you're done. This is safe but requires a bunch of temporary disk space or
heap memory.
2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
mz_zip_writer_init_from_reader(),
append new files as needed, then finalize the archive which will write an
updated central directory to the
original archive. (This is basically what
mz_zip_add_mem_to_archive_file_in_place() does.) There's a
possibility that the archive's central directory could be lost with this
method if anything goes wrong, though.
- ZIP archive support limitations:
No zip64 or spanning support. Extraction functions can only handle
unencrypted, stored or deflated files.
Requires streams capable of seeking.
* This is a header file library, like stb_image.c. To get only a header file,
either cut and paste the
below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then
include miniz.c from it.
* Important: For best perf. be sure to customize the below macros for your
target platform:
#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
#define MINIZ_LITTLE_ENDIAN 1
#define MINIZ_HAS_64BIT_REGISTERS 1
* On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before
including miniz.c to ensure miniz
uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be
able to process large files
(i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).

// Build a "canonical" Huffman code table:
// - for each (uncompressed) symbol, hcode contains the length

// - canonical codes are computed and stored in hcode
// - the rules for constructing canonical codes are as follows:
// * shorter codes (if filled with zeroes to the right)
// have a numerically higher value than longer codes
// * for codes with the same length, numerical values
// increase with numerical symbol values
// - because the canonical code table can be constructed from
// symbol lengths alone, the code table can be transmitted
// without sending the actual code values

% CannyEdgeImage() uses a multi-stage algorithm to detect a wide range of
% edges in images.

% The format of the CannyEdgeImage method is:
%
% Image *CannyEdgeImage(const Image *image,const double radius,
% const double sigma,const double lower_percent,
% const double upper_percent,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o radius: the radius of the gaussian smoothing filter.
%
% o sigma: the sigma of the gaussian smoothing filter.
%
% o lower_percent: percentage of edge pixels in the lower threshold.
%
% o upper_percent: percentage of edge pixels in the upper threshold.
%
% o exception: return any errors or warnings in this structure.

% GetImageChannelFeatures() returns features for each channel in the image in
% each of four directions (horizontal, vertical, left and right diagonals)
% for the specified distance. The features include the angular second
% moment, contrast, correlation, sum of squares: variance, inverse difference
% moment, sum average, sum varience, sum entropy, entropy, difference variance,% difference entropy, information measures of correlation 1, information
% measures of correlation 2, and maximum correlation coefficient. You can
% access the red channel contrast, for example, like this:
%
% channel_features=GetImageChannelFeatures(image,1,exception);
% contrast=channel_features[RedChannel].contrast[0];
%
% Use MagickRelinquishMemory() to free the features buffer.
%
% The format of the GetImageChannelFeatures method is:
%
% ChannelFeatures *GetImageChannelFeatures(const Image *image,
% const size_t distance,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o distance: the distance.
%
% o exception: return any errors or warnings in this structure.

% Use HoughLineImage() in conjunction with any binary edge extracted image (we
% recommand Canny) to identify lines in the image. The algorithm accumulates
% counts for every white pixel for every possible orientation (for angles from
% 0 to 179 in 1 degree increments) and distance from the center of the image to
% the corner (in 1 px increments) and stores the counts in an accumulator
% matrix of angle vs distance. The size of the accumulator is 180x(diagonal/2).% Next it searches this space for peaks in counts and converts the locations
% of the peaks to slope and intercept in the normal x,y input image space. Use
% the slope/intercepts to find the endpoints clipped to the bounds of the
% image. The lines are then drawn. The counts are a measure of the length of
% the lines.
%
% The format of the HoughLineImage method is:
%
% Image *HoughLineImage(const Image *image,const size_t width,
% const size_t height,const size_t threshold,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o width, height: find line pairs as local maxima in this neighborhood.
%
% o threshold: the line count threshold.
%
% o exception: return any errors or warnings in this structure.

% MeanShiftImage() delineate arbitrarily shaped clusters in the image. For
% each pixel, it visits all the pixels in the neighborhood specified by
% the window centered at the pixel and excludes those that are outside the
% radius=(window-1)/2 surrounding the pixel. From those pixels, it finds those
% that are within the specified color distance from the current mean, and
% computes a new x,y centroid from those coordinates and a new mean. This new
% x,y centroid is used as the center for a new window. This process iterates
% until it converges and the final mean is replaces the (original window
% center) pixel value. It repeats this process for the next pixel, etc.,
% until it processes all pixels in the image. Results are typically better with
% colorspaces other than sRGB. We recommend YIQ, YUV or YCbCr.
%
% The format of the MeanShiftImage method is:
%
% Image *MeanShiftImage(const Image *image,const size_t width,
% const size_t height,const double color_distance,
% ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o width, height: find pixels in this neighborhood.
%
% o color_distance: the color distance.
%
% o exception: return any errors or warnings in this structure.

@brief Refreshes the protein references for all peptide hits in a vector of PeptideIdentifications and adds target/decoy information.
All peptide and protein hits are annotated with target/decoy information, using the meta value "target_decoy". For proteins the possible values are "target" and "decoy",
depending on whether the protein accession contains the decoy pattern (parameter @p decoy_string) as a suffix or prefix, respectively (see parameter @p prefix).
For peptides, the possible values are "target", "decoy" and "target+decoy", depending on whether the peptide sequence is found only in target proteins,
only in decoy proteins, or in both. The target/decoy information is crucial for the @ref TOPP_FalseDiscoveryRate tool.
(For FDR calculations, "target+decoy" peptide hits count as target hits.)
@note Make sure that your protein names in the database contain a correctly formatted decoy string. This can be ensured by using @ref UTILS_DecoyDatabase.
If the decoy identifier is not recognized successfully all proteins will be assumed to stem from the target-part of the query.<br>
E.g., "sw|P33354_DECOY|YEHR_ECOLI Uncharacterized lipop..." is <b>invalid</b>, since the tool has no knowledge of how SwissProt entries are build up.
A correct identifier could be "DECOY_sw|P33354|YEHR_ECOLI Uncharacterized li ..." or "sw|P33354|YEHR_ECOLI_DECOY Uncharacterized li", depending on whether you are
using prefix or suffix annotation.<br>
Some helpful target/decoy statistics will be reported when done.
By default this tool will fail if an unmatched peptide occurs, i.e. if the database does not contain the corresponding protein.
You can force it to return successfully in this case by using the flag @p allow_unmatched.
Search engines (such as Mascot) will replace ambiguous amino acids ('B', 'J', 'Z' and 'X') in the protein database with unambiguous amino acids in the reported peptides, e.g. exchange 'X' with 'H'.
This will cause such peptides to not be found by exactly matching their sequences to the protein database.
However, we can recover these cases by using tolerant search for ambiguous amino acids in the protein sequence. This is done by default with up to four amino acids
per peptide hit. If you only want exact matches, set @p aaa_max to zero (but expect that unmatched peptides might occur)!
Leucine/Isoleucine:
Further complications can arise due to the presence of the isobaric amino acids isoleucine ('I') and leucine ('L') in protein sequences.
Since the two have the exact same chemical composition and mass, they generally cannot be distinguished by mass spectrometry.
If a peptide containing 'I' was reported as a match for a spectrum, a peptide containing 'L' instead would be an equally good match (and vice versa).
To account for this inherent ambiguity, setting the flag @p IL_equivalent causes 'I' and 'L' to be considered as indistinguishable.@n
For example, if the sequence "PEPTIDE" (matching "Protein1") was identified as a search hit,
but the database additionally contained "PEPTLDE" (matching "Protein2"), running PeptideIndexer with the @p IL_equivalent option would
report both "Protein1" and "Protein2" as accessions for "PEPTIDE".
(This is independent of ambiguous matching via @p aaa_max.)
Additionally, setting this flag will convert all 'J's in any protein sequence to 'I'. This way, no tolerant search is required for 'J' (but is still possible for all
the other ambiguous amino acids).
If @p write_protein_sequences is requested and @p IL_equivalent is set as well, both the I/L-version and unmodified protein sequences need to be stored internally.
This requires some extra memory, roughly equivalent to the size of the FASTA database file itself.
Enzyme specificity:
Once a peptide sequence is found in a protein sequence, this does <b>not</b> imply that the hit is valid! This is where enzyme specificity comes into play.
By default, we demand that the peptide is fully tryptic (i.e. the enzyme parameter is set to "trypsin" and specificity is "full").
So unless the peptide coincides with C- and/or N-terminus of the protein, the peptide's cleavage pattern should fulfill the trypsin cleavage rule [KR][^P].
We make two exceptions to the specificity constraints:
1) for peptides starting at the second or third position of a protein are still considered N-terminally specific,
since the residues can be cleaved off in vivo; X!Tandem reports these peptides. For example, the two peptides ABAR and LABAR would both match a protein starting with MLABAR.
2) adventitious cleavage at Asp|Pro (Aspartate/D | Proline/P) is allowed for all enzymes (as supported by X!Tandem), i.e. counts as a proper cleavage site (see http://www.thegpm.org/tandem/release.html).
You can relax the requirements further by choosing <tt>semi-tryptic</tt> (only one of two "internal" termini must match requirements)
or <tt>none</tt> (essentially allowing all hits, no matter their context). These settings should not be used (due to high risk of reporting false positives),
unless the search engine was instructed to search peptides in the same way.
The FASTA file should not contain duplicate protein accessions (since accessions are not validated) if a correct unique-matching annotation is important (target/decoy annotation is still correct).
Threading:
This tool support multiple threads (@p threads option) to speed up computation, at the cost of little extra memory.

/**
@brief Re-index peptide identifications honoring enzyme cutting rules, ambiguous amino acids and target/decoy hits.
Template parameter 'T' can be either TFI_File or TFI_Vector. If the data is already available, use TFI_Vector and pass the vector.
If the data is still in a FASTA file and its not needed afterwards for additional processing, use TFI_File and pass the filename.
PeptideIndexer refreshes target/decoy information and mapping of peptides to proteins.
The target/decoy information is crucial for the @ref TOPP_FalseDiscoveryRate tool. (For FDR calculations, "target+decoy" peptide hits count as target hits.)
PeptideIndexer allows for ambiguous amino acids (B|J|Z|X) in the protein database, but not in the peptide sequences.
For the latter only I/L can be treated as equivalent (see 'IL_equivalent' flag), but 'J' is not allowed.
Enzyme cutting rules and partial specificity can be specified.
Resulting protein hits appear in the order of the FASTA file, except for orphaned proteins, which will appear first with an empty target_decoy metavalue.
Duplicate protein accessions & sequences will not raise a warning, but create multiple hits (PeptideIndexer scans over the FASTA file once for efficiency
reasons, and thus might not see all accessions & sequences at once).
All peptide and protein hits are annotated with target/decoy information, using the meta value "target_decoy".
For proteins the possible values are "target" and "decoy", depending on whether the protein accession contains the decoy pattern (parameter @p decoy_string)
as a suffix or prefix, respectively (see parameter @p prefix).
Peptide hits are annotated with metavalue 'protein_references', and if matched to at least one protein also with metavalue 'target_decoy'.
The possible values for 'target_decoy' are "target", "decoy" and "target+decoy",
depending on whether the peptide sequence is found only in target proteins, only in decoy proteins, or in both. The metavalue is not present, if the peptide is unmatched.
Runtime: PeptideIndexer is usually very fast (loading and storing the data takes the most time) and search speed can be further improved (linearly), but using more threads.
Avoid allowing too many (>=4) ambiguous amino acids if your database contains long stretches of 'X' (exponential search space).
@param proteins A list of proteins -- either read piecewise from a FASTA file or as existing vector of FASTAEntries.
@param prot_ids Resulting protein identifications associated to pep_ids (will be re-written completely)
@param pep_ids Peptide identifications which should be search within @p proteins and then linked to @p prot_ids
@return Exit status codes.

/* miniz.c v1.15 - public domain deflate/inflate, zlib-subset, ZIP
reading/writing/appending, PNG writing
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
http://www.ietf.org/rfc/rfc1951.txt
Most API's defined in miniz.c are optional. For example, to disable the
archive related functions just define
MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO
(see the list below for more macros).
* Change History
10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
release with Zip64 support (almost there!):
- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
(thanks kahmyong.moon@hp.com) which could cause locate files to not find
files. This bug
would only have occured in earlier versions if you explicitly used this
flag, OR if you used mz_zip_extract_archive_file_to_heap() or
mz_zip_add_mem_to_archive_file_in_place()
(which used this flag). If you can't switch to v1.15 but want to fix
this bug, just remove the uses of this flag from both helper funcs (and of
course don't use the flag).
- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
pUser_read_buf is not NULL and compressed size is > uncompressed size
- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
compressed data from directory entries, to account for weird zipfiles which
contain zero-size compressed data on dir entries.
Hopefully this fix won't cause any issues on weird zip archives,
because it assumes the low 16-bits of zip external attributes are DOS
attributes (which I believe they always are in practice).
- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
internal attributes, just the filename and external attributes
- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
- Added cmake support for Linux builds which builds all the examples,
tested with clang v3.3 and gcc v4.6.
- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
- Merged MZ_FORCEINLINE fix from hdeanclark
- Fix <time.h> include before config #ifdef, thanks emil.brink
- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
(super useful for OpenGL apps), and explicit control over the compression
level (so you can
set it to 1 for real-time compression).
- Merged in some compiler fixes from paulharris's github repro.
- Retested this build under Windows (VS 2010, including static analysis),
tcc 0.9.26, gcc v4.6 and clang v3.3.
- Added example6.c, which dumps an image of the mandelbrot set to a PNG
file.
- Modified example2 to help test the
MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
possible src file fclose() leak if alignment bytes+local header file write
faiiled
- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader():
Was pushing the wrong central dir header offset, appears harmless in this
release, but it became a problem in the zip64 branch
5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE,
#include <time.h> (thanks fermtect).
5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
re-ran a randomized regression test on ~500k files.
- Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
(static analysis) option and fixed all warnings (except for the silly
"Use of the comma-operator in a tested expression.." analysis warning,
which I purposely use to work around a MSVC compiler warning).
- Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
tested Linux executables. The codeblocks workspace is compatible with
Linux+Win32/x64.
- Added miniz_tester solution/project, which is a useful little app
derived from LZHAM's tester app that I use as part of the regression test.
- Ran miniz.c and tinfl.c through another series of regression testing on
~500,000 files and archives.
- Modified example5.c so it purposely disables a bunch of high-level
functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
MINIZ_NO_STDIO bug report.)
- Fix ftell() usage in examples so they exit with an error on files which
are too large (a limitation of the examples, not miniz itself).
4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple
minor level_and_flags issues in the archive API's.
level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce
Dawson <bruced@valvesoftware.com> for the feedback/bug report.
5/28/11 v1.11 - Added statement from unlicense.org
5/27/11 v1.10 - Substantial compressor optimizations:
- Level 1 is now ~4x faster than before. The L1 compressor's throughput
now varies between 70-110MB/sec. on a
- Core i7 (actual throughput varies depending on the type of data, and x64
vs. x86).
- Improved baseline L2-L9 compression perf. Also, greatly improved
compression perf. issues on some file types.
- Refactored the compression code for better readability and
maintainability.
- Added level 10 compression level (L10 has slightly better ratio than
level 9, but could have a potentially large
drop in throughput on some files).
5/15/11 v1.09 - Initial stable release.
* Low-level Deflate/Inflate implementation notes:
Compression: Use the "tdefl" API's. The compressor supports raw, static,
and dynamic blocks, lazy or
greedy parsing, match length filtering, RLE-only, and Huffman-only streams.
It performs and compresses
approximately as well as zlib.
Decompression: Use the "tinfl" API's. The entire decompressor is
implemented as a single function
coroutine: see tinfl_decompress(). It supports decompression into a 32KB
(or larger power of 2) wrapping buffer, or into a memory
block large enough to hold the entire file.
The low-level tdefl/tinfl API's do not make any use of dynamic memory
allocation.
* zlib-style API notes:
miniz.c implements a fairly large subset of zlib. There's enough
functionality present for it to be a drop-in
zlib replacement in many apps:
The z_stream struct, optional memory allocation callbacks
deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
inflateInit/inflateInit2/inflate/inflateEnd
compress, compress2, compressBound, uncompress
CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
routines.
Supports raw deflate streams or standard zlib streams with adler-32
checking.
Limitations:
The callback API's are not implemented yet. No support for gzip headers or
zlib static dictionaries.
I've tried to closely emulate zlib's various flavors of stream flushing
and return status codes, but
there are no guarantees that miniz.c pulls this off perfectly.
* PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
originally written by
Alex Evans. Supports 1-4 bytes/pixel images.
* ZIP archive API notes:
The ZIP archive API's where designed with simplicity and efficiency in
mind, with just enough abstraction to
get the job done with minimal fuss. There are simple API's to retrieve file
information, read files from
existing archives, create new archives, append new files to existing
archives, or clone archive data from
one archive to another. It supports archives located in memory or the heap,
on disk (using stdio.h),
or you can specify custom file read/write callbacks.
- Archive reading: Just call this function to read a single file from a
disk archive:
void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
char *pArchive_name,
size_t *pSize, mz_uint zip_flags);
For more complex cases, use the "mz_zip_reader" functions. Upon opening an
archive, the entire central
directory is located and read as-is into memory, and subsequent file access
only occurs when reading individual files.
- Archives file scanning: The simple way is to use this function to scan a
loaded archive for a specific file:
int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
const char *pComment, mz_uint flags);
The locate operation can optionally check file comments too, which (as one
example) can be used to identify
multiple versions of the same file in an archive. This function uses a
simple linear search through the central
directory, so it's not very fast.
Alternately, you can iterate through all the files in an archive (using
mz_zip_reader_get_num_files()) and
retrieve detailed info on each file by calling mz_zip_reader_file_stat().
- Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
immediately writes compressed file data
to disk and builds an exact image of the central directory in memory. The
central directory image is written
all at once at the end of the archive file when the archive is finalized.
The archive writer can optionally align each file's local header and file
data to any power of 2 alignment,
which can be useful when the archive will be read from optical media. Also,
the writer supports placing
arbitrary data blobs at the very beginning of ZIP archives. Archives
written using either feature are still
readable by any ZIP tool.
- Archive appending: The simple way to add a single file to an archive is
to call this function:
mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
const char *pArchive_name,
const void *pBuf, size_t buf_size, const void *pComment, mz_uint16
comment_size, mz_uint level_and_flags);
The archive will be created if it doesn't already exist, otherwise it'll be
appended to.
Note the appending is done in-place and is not an atomic operation, so if
something goes wrong
during the operation it's possible the archive could be left without a
central directory (although the local
file headers and file data will be fine, so the archive will be
recoverable).
For more complex archive modification scenarios:
1. The safest way is to use a mz_zip_reader to read the existing archive,
cloning only those bits you want to
preserve into a new archive using using the
mz_zip_writer_add_from_zip_reader() function (which compiles the
compressed file data as-is). When you're done, delete the old archive and
rename the newly written archive, and
you're done. This is safe but requires a bunch of temporary disk space or
heap memory.
2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
mz_zip_writer_init_from_reader(),
append new files as needed, then finalize the archive which will write an
updated central directory to the
original archive. (This is basically what
mz_zip_add_mem_to_archive_file_in_place() does.) There's a
possibility that the archive's central directory could be lost with this
method if anything goes wrong, though.
- ZIP archive support limitations:
No zip64 or spanning support. Extraction functions can only handle
unencrypted, stored or deflated files.
Requires streams capable of seeking.
* This is a header file library, like stb_image.c. To get only a header file,
either cut and paste the
below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then
include miniz.c from it.
* Important: For best perf. be sure to customize the below macros for your
target platform:
#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
#define MINIZ_LITTLE_ENDIAN 1
#define MINIZ_HAS_64BIT_REGISTERS 1
* On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before
including miniz.c to ensure miniz
uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be
able to process large files
(i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).
