2013-06-09fail in CopyFile if the FileFds have error flag setDavid Kalnischkies
Testing for global PendingErrors in users of CopyFile is incorrect in so far as unrelated errors will prevent us from copying perfectly fine files and checking for the validity of the files is just better in CopyFiles as it already checks if files are at least opened. Add also a higher-level error message to the error stack if it fails.
2013-06-09OpenDescriptor should autoclose fd always on errorDavid Kalnischkies
OpenInternDescriptor failures would cause additional errors to be generated by double-closing an fd. Other errors (although these are generated if the method is used incorrectly, so unlikely) didn't close the fd aswell. Closes: 704608
2013-06-09set Fail flag in FileFd on all errors consistentlyDavid Kalnischkies
Previously some errors would set the Fail flag while some didn't without a clear reason as all errors leave a bad FileFd behind, so we use a helper now to ensure that all errors set the flag.
2013-06-06fix double free (closes: #711045)Michael Vogt
2013-03-10various simple changes to fix cppcheck warningsDavid Kalnischkies
2012-08-04* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- remove _POSIX_SYNCHRONIZED_IO guard in FileFd::Sync() around fsync as this guard is only needed for fdatasync and not defined on hurd
2012-05-22* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- dup() given compressed fd in OpenDescriptor if AutoClose is disabled as otherwise gzclose() and co will close it
2012-05-16* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- ensure that we close compressed fds, wait for forks and such even if the FileFd itself is set to not autoclose the given Fd
2012-05-10ensure that d is set before accessing itDavid Kalnischkies
2012-05-10ensure that in error conditions the Fail flag is setDavid Kalnischkies
2012-05-10collect zombie (de)compressor processes on reopenDavid Kalnischkies
2012-05-09ensure that we do init d only once and especially not with its ownDavid Kalnischkies
content as this causes some "interesting" hickups resulting in segfaults as it seems (Closes: #554387, #670979)
2012-05-09* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- check that the fd which are closed are valid
2012-04-19* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- redirect stderr from compressors to /dev/null
2012-04-11use a static FileFd::Write overload to reduce duplication of write()-retry codeDavid Kalnischkies
2012-04-05 - add libbz2-dev as new build-dependencyDavid Kalnischkies
- remove the libz-dev alternative from zlib1g-dev build-dependency - do the same for bz2 builtin if available * apt-pkg/contrib/fileutl.cc: - use libz2 library for (de)compression instead of the bzip2 binary as the first is a dependency of dpkg and the later just priority:optional so we gain 'easier' access to bz2-compressed Translation files this way
2012-04-05if we have zlib builtin insert add a dummy gzip compressor for FileFDDavid Kalnischkies
2012-04-05detect zlib correctly. We still don't allow to build without it to remainDavid Kalnischkies
compatible with users accessing it directly, but this prepares for a drop of this strict requirement in the future
2012-03-06* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- do not warn about the ignoring of directories (Closes: #662762)
2012-02-11* apt-pkg/cachefile.cc:David Kalnischkies
- clean up lost atomic cachefiles with 'clean' (Closes: #650513)
2012-02-03rework previous patch to avoid changing the inline codeMichael Vogt
2012-01-18* apt-pkg/contrib/fileutl.h:David Kalnischkies
- 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…
2012-01-18improve error reporting in case of errors in combination with zlibDavid Kalnischkies
2011-12-18usage of Skipping in pipes can't work, so we ignore-read insteadDavid Kalnischkies
Also, read only one char in each step of ReadLine instead of back-"seeking"
2011-12-17keep track of where we are in a filedescriptor so we can use it as Tell()David Kalnischkies
information if we are working on a pipe which can't seek
2011-12-16try seeking on fds opened with OpenDescriptor before giving upDavid Kalnischkies
2011-12-15refactor compressor calling so that we don't (need to) export ExecCompressorDavid Kalnischkies
anymore and therefore are also able to drop quiet a bit of duplicated code
2011-12-14use FileFd instead of forking the compression childs by handDavid Kalnischkies
2011-12-13allow Open() and OpenDescriptor() to be called with a CompressorDavid Kalnischkies
2011-12-13note to myself: In case you rename something, make sure that you haveDavid Kalnischkies
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…
2011-12-13Allow the FileFd to use an external Compressor to uncompress a given fileDavid Kalnischkies
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.
2011-12-11 - add a ReadLine methodDavid Kalnischkies
- drop the explicit export of gz-compression handling
2011-12-10* apt-pkg/contrib/fileutl.{h,cc}:David Kalnischkies
- implement a ModificationTime method for FileFd
2011-12-10enable FileFd to guess the compressor based on the filename if requested orDavid Kalnischkies
to search for compressed silbings of the given filename and use this guessing instead of hardcoding Gzip compression
2011-11-29split up the OpenMode into OpenMode and CompressionMode andDavid Kalnischkies
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.
2011-09-13merge with debian/experimentalDavid Kalnischkies
2011-09-13Support large files in the complete toolset. Indexes of thisDavid Kalnischkies
size are pretty unlikely for now, but we need it for deb packages which could become bigger than 4GB now (LP: #815895)
2011-09-13reorder includes: add <config.h> if needed and include it at firstDavid Kalnischkies
2011-07-28* apt-pkg/contrib/fileutl.{cc,h}:Michael Vogt
- 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
2011-03-10merged the lp:~mvo/apt/mvo branchMichael Vogt
2011-03-03* apt-pkg/contrib/fileutl.cc, apt-pkg/deb/dpkgpm.cc:Michael Vogt
- honor Dpkg::Chroot-Directory in the RunScripts*() methods
2011-02-14* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- 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
2011-02-14use inttypes to avoid suprises with different type sizesDavid Kalnischkies
2011-02-13* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- reorder the loaded filesize bytes for big endian (Closes: #612986) Thanks to Jörg Sommer for the detailed analyse!
2011-01-13ignore non-regular files in GetListOfFilesInDir (Closes: #594694)David Kalnischkies
2011-01-12* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- add a RealFileExists method and check that your configuration files are real files to avoid endless loops if not (Closes: #604401)
2010-10-21* apt-pkg/contrib/fileutl.cc:David Kalnischkies
- 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)
2010-10-13apt-pkg/contrib/fileutl.cc: fix FileFd::Size() for files that are empty or ↵Michael Vogt
for non-gzip files
2010-10-13* apt-pkg/contrib/fileutl.cc:Martin Pitt
- Fix FileFd::Size() for gzipped files to give the size of the uncompressed data. This fixes cache progress building progress going way over 100%.
2010-09-06rename the newly public CheckDirectory method to CreateAPTDirectoryIfNeededDavid Kalnischkies
to give a better indication what this method will do if called.
