This commit imports the changes to the CHANGELOG.md in the backports
branch after the 1.0.4 release and updates the package scripts to
point to the new release.
In addition, the version numbers in configure.ac are update to more
closeley reflect reality, i.e. set the current so version and set the
package version to 1.1.0 which will be the next release from master.
The unreleased changes in master are also added to the CHANGELOG.md.

This function creates a block processor from a structure describing it.
A stub implementation for the old sqfs_block_processor_create is added
that simply sets up such a struct and forwards the call.
The current version of the description struct only contains the exact
same parameters and a size field at the beginning.
This approach is supposed to make extending the range of parameters
easier without breaking ABI compatibillity.
Currently already planned are:
- Adding a sqfs_file_t pointer to double-check when deduplicating
fragments.
- When the scanning code reaches a usable state, add the abillity
to pass scanned fragment data, so the block processor can be used
for appending to an existing image.

Keeping a list of fragments stored away in the current fragment block
and consolidating them in the thread pool takes them out of circulation.
If we have a lot of tiny fragments, this can lead to a situation where
all the limit is reached, but we cannot do anything, because we are
waiting for a block to complete, but they are all attached to the
current fragment block and the queue is empty.

It looks like the last commit missed a couple more occurences
where '\' was treated incorrectly.
Fixes were still needed in sqfs_dir_reader_find_by_path and
sqfs_dir_reader_get_full_hierarchy.
This path is used in extras/browse.c.
|
|
All paths were canonicalized internally, which includes filtering
sequences of slashes and converting backslashes to slashes.
Furthermore, when unpacking files, filenames are sanity checked
and rejected if they contain forward OR backward slashes.
This is a problem on Unix-like systems, where files containing
backslashes are a legitimate use case (*cough* SystemD *cough*).
This patch removes the backslash conversion from the canonicalization
and modifies the sanity check to reject backslashes only on Windows.

The upstream package for bzip2 does not provide a pkg-config file.
Some GNU/Linux distributions (e.g. Fedora) have added one, but others
like Debian have not.
Since Debian and its deriatives are much more wide spread, this makes
the existance of a pkg-config file the exception, rather than the
norm.
This commit replaces the pkg-config based check in configure.ac with
a manual check based on AC_CHECK_LIB and AC_CHECK_HEADERS, similar to
what is already done for lzo2.

Instead of comparing (compresed, disk-size, checksum) tuples to find
block matches, do an exact, byte-for-byte comparison of the data
stored on disk to avoid the possibility of a spurious colision.
Since this is the desired behaviour, make it the default, optionally
overrideable through a flag.

The sqsf_writer is moved to a separate header, as well as the compressor
related stuff. The statistics function is moved into the writer code, as
this is the only place that actually uses it. The writer code itself is
split up into a hand full of file in their own subdirectory.

Some of the build scripts contain hashes of the release tarballs. When
releasing a new version, in addition to bumping all the version numbers,
this would require the amazing stunt of putting the hashes of the
release tarball into the release tarball itself, for a number of
different hash algorithms.

In addition to skipping non-prefixed files and stripping the prefix
off of entries we accept, the targets of links also have to be altered,
since they can be absolute paths with the root prefix attached.
This can affect symbolic links as well. Altough they are allowed to
point into nowhere, across filesystem boundaries, they may also be
absolute paths refering to existing locations in the filesystem, so
no distinction is made by default.
However, the later may be intended (e.g. only a subdirectory is packed
into SquashFS and then mounted at that location), so a command line
switch is added to disable symlink retargetting.

If rdsquashfs describes a filesystem, is configured to use a prefix-path
and a file contains a space, the resulting input path has the prefix
printed as is and the rest of the string in quotation marks.
gensquashfs simply takes the entire rest of the line as is as its
input path and no longer finds the file.
Fix this by omitting the escapes and quotation marks for the
input path.

Modify the man pages and help texts to mention compression support, make
the help option display a list of supported compressors.
Also clarify the squashfs compressor list in the help text to state that
the list shows block compressors supported for SquashFS compression.

Streaming compression was added fairly recently to zstd (and then
the API was changed a few times).
Rather than rely on libzstd versioning macros, this commit adds an
m4 script to test at configure time if the enums/functions we need
are available by trying to compile a small sample.

If tar2sqfs and sqfs2tar want to use comperssion via libfstream, they
need to link against the compressor libraries.
Also, libfstream may need the apropriate cflags to access the headers
on some platforms.
