- store the offset in the internal fd before calculate size of
the zlib-handled file to jump back to this place again
It jumped back to the position of the content - which is wrong as
the internal fd is compressed and even reseting to the beginning of
the file doesn't work as zlib uses an internal buffer, so while we
might haven't read anything yet zlib might have done so already…
|
|
|
|
Also, read only one char in each step of ReadLine instead of back-"seeking"
|
|
information if we are working on a pipe which can't seek
|
|
|
|
anymore and therefore are also able to drop quiet a bit of duplicated code
|
|
|
|
|
|
renamed it everywhere as otherwise stuff "magically" starts to fail…
Fixes commit 2209 as the mixture of #define names generates a lovely
compilable but non-functional mixture of gzip usage…
|
|
internally so that it is exported and can be used like a "normal"
uncompressed file with FileFd
This allows us to hide th zlib usage in the implementation and use gzip
instead if we don't have zlib builtin (the same for other compressors).
The code includes quiet a few FIXME's so while all tests are working
it shouldn't be used just yet outside of libapt as it might break.
|
|
- drop the explicit export of gz-compression handling
|
|
- implement a ModificationTime method for FileFd
|
|
to search for compressed silbings of the given filename and use this guessing
instead of hardcoding Gzip compression
|
|
provide ReadOnly, WriteOnly and ReadWrite as flags alongside
the additional flags as decompression will be one-way later,
but certain parts really depend on Write* openmodes being
ReadWrite opens, so we will have to fail for those.

size are pretty unlikely for now, but we need it for deb
packages which could become bigger than 4GB now (LP: #815895)
|
|
|
|
- add GetModificationTime() helper
* apt-pkg/pkgcachegen.cc:
- regenerate the cache if the sources.list changes to ensure
that changes in the ordering there will be honored by apt
* apt-pkg/sourcelist.{cc,h}:
- add pkgSourceList::GetLastModifiedTime() helper
|
|
|
|
- honor Dpkg::Chroot-Directory in the RunScripts*() methods
|
|
- really detect bigendian machines by including config.h,
so we can really (Closes: #612986)
* apt-pkg/contrib/mmap.cc:
- Base has as 'valid' failure states 0 and -1 so add a simple
validData method to check for failure states
|
|
|
|
- reorder the loaded filesize bytes for big endian (Closes: #612986)
Thanks to Jörg Sommer for the detailed analyse!
|
|
|
|
- add a RealFileExists method and check that your configuration files
are real files to avoid endless loops if not (Closes: #604401)
|
|
- Add a FileFd::FileSize() method to get the size of the underlying
file and not the size of the content in the file as FileFd::Size()
does - the sizes can differ since the direct gzip integration
* methods/{gzip,bzip2}.cc:
- use FileSize() to determine if the file is invalid (Closes: #600852)
|
|
for non-gzip files
|
|
- Fix FileFd::Size() for gzipped files to give the size of the
uncompressed data. This fixes cache progress building progress going way
over 100%.
|
|
to give a better indication what this method will do if called.
|
|
- create Dir::Log if needed to support /var/log as tmpfs or similar,
inspired by Thomas Bechtold, thanks! (Closes: #523919, LP: #220239)
Easily done by moving a private method from pkgAcquire into the public
area of fileutl.cc to be able to use it also in here
|
|
- apply SilentlyIgnore also on files without an extension
|
|
|
|
|
|
- Add FileFd::OpenDescriptor() (needed for python-apt's #383617).
|
|
* debian/rules:
- Make DEB_BUILD_OPTIONS=noopt actually work by passing the right
CXXFLAGS.
* apt-pkg/contrib/fileutl.{h,cc}:
- Add support for reading of gzipped files with the new "ReadOnlyGzip"
OpenMode. (Closes: #188407)
- Link against zlib (in apt-pkg/makefile) and add zlib build dependency.
- [ABI BREAK] This adds a new private member to FileFd, but its
initialization is in the public header file.
* configure.in:
- Check for zlib library and headers.
* apt-pkg/acquire-item.cc, apt-pkg/deb/debindexfile.cc,
apt-pkg/deb/debrecords.cc, apt-pkg/deb/debsrcrecords.h,
cmdline/apt-cache.cc:
- Open Packages, Sources, and Translations indexes in "ReadOnlyGzip" mode.
* apt-pkg/deb/debindexfile.cc:
- If we do not find uncompressed package/source/translation indexes, look
for gzip compressed ones.
* apt-pkg/acquire-item.cc:
- If the Acquire::GzipIndexes option is true and we download a gzipped
index file, keep it as it is (and rename to .gz) instead of
uncompressing it.
* doc/apt.conf.5.xml:
- Document the new Acquire::GzipIndexes option.
* doc/po/apt-doc.pot, doc/po/de.po:
- German translation of new Acquire::GzipIndexes option.
* Add test/test-indexes.sh:
- Test behaviour of index retrieval and usage, in particular with
uncompressed and gzip compressed indexes.
* methods/gzip.cc: With FileFd now being able to read gzipped files, there
is no need for the gzip method any more to spawn an external gzip process.
Rewrite it to use FileFd directly, which makes the code a lot simpler, and
also using less memory and overhead.
|
|
will be tried twice e.g. in an "apt-get update" run and every other piece
of code closing the FileFd manual before the destructor will do it again.
|
|
Drop the ".gz" extension check in FileFd::Open() in ReadOnlyGzip mode, to not
depend on a particular file extension. This allows rewriting the gzip method
using internal decompression (on ".decomp" files).
This requires a zlib bug workaround in FileFd::Close(): When opening an empty
file with gzdopen(), gzclose() fails with Z_BUF_ERROR. Do not count this as a
failure.
|
|
|
|
|
|
- Make FileFd replace files atomically in WriteTemp mode (for cache, etc).
|
|
- show notice about ignored file instead of being always silent
- add a Dir::Ignore-Files-Silently list option to control the notice
*
|
|
expects the compressed contents to stay (such as the copy backend, or when using file:// repositories. Instead, introduce a new ReadOnlyGzip mode and use that where needed
|
|
- Add support for transparent reading of gzipped files.
- Link against zlib (in apt-pkg/makefile) and add zlib build dependency.
|
|
- add a parent-guarded "mkdir -p" as CreateDirectory()
* apt-pkg/acquire.{cc,h}:
- add a delayed constructor with Setup() for success reporting
- check for and create directories in Setup if needed instead of
error out unfriendly in the Constructor (Closes: #523920, #525783)
- optional handle a lock file in Setup()
* cmdline/apt-get.cc:
- remove the lock file handling and let Acquire take care of it instead
|
|
|

- Fix the newly introduced method GetListOfFilesInDir to not
accept every file if no extension is enforced
(= restore old behaviour). (Closes: #565213)
* apt-pkg/policy.cc:
- accept also partfiles with "pref" file extension as valid
* apt-pkg/contrib/configuration.cc:
- accept also partfiles with "conf" file extension as valid
* doc/apt.conf.5.xml:
- reorder description and split out syntax
- add partfile name convention (Closes: #558348)
* doc/apt_preferences.conf.5.xml:
- describe partfile name convention also here
* apt-pkg/deb/dpkgpm.cc:
- don't segfault if term.log file can't be opened.
Thanks Sam Brightman for the patch! (Closes: #475770)
* doc/*:
- replace the per language addendum with a global addendum
- add a explanation why translations include (maybe) english
parts to the new global addendum (Closes: #561636)
* apt-pkg/contrib/strutl.cc:
- fix malloc asseration fail with ja_JP.eucJP locale in
apt-cache search. Thanks Kusanagi Kouichi! (Closes: #548884)

* spot & fix various typos in all manpages
* German manpage translation update

- instruct debiandoc to build files with utf-8 encoding
* buildlib/tools.m4:
- fix some warning from the buildtools

too many or too big patches (Closes: #554349)
* debian/control:
- let all packages depend on ${misc:Depends}
* share/*-archive.gpg:
- remove the horrible outdated files. We already depend on
the keyring so we don't need to ship our own version
* cmdline/apt-key:
- errors out if wget is not installed (Closes: #545754)
- add --keyring option as we have now possibly many
* methods/gpgv.cc:
- pass all keyrings (TrustedParts) to gpgv instead of
using only one trusted.gpg keyring (Closes: #304846)
* methods/https.cc:
- finally merge the rest of the patchset from Arnaud Ebalard
with the CRL and Issuers options, thanks! (Closes: #485963)

warning: suggest explicit braces to avoid ambiguous ‘else’
|
|
- show error details of failed methods
* apt-pkg/contrib/fileutl.cc:
- if a process aborts with signal, show signal number
* methods/http.cc:
- ignore SIGPIPE, we deal with EPIPE from write in
HttpMethod::ServerDie() (LP: #385144)

Donlan <bdonlan@fushizen.net> for the patch. Closes: #482476
