2012-07-24for filesystems not supporting mmap'ing a file we need to use aDavid Kalnischkies
SyncToFd dummy just as we did for compressed files in 0.9.5
2012-07-24trigger the usage of the fallback code for kfreebsd also in theDavid Kalnischkies
second (filebased) constructor of DynamicMMap (Closes: #677704)
2012-07-20* apt-pkg/contrib/mmap.cc:David Kalnischkies
- refer to APT::Cache-Start in case the growing failed as if -Limit is really the offender it will be noted in a previous error message.
2012-06-16Fix previous commit: Do not call memset() if realloc() returned NULL.Julian Andres Klode
2012-06-16Zero out the new memory allocated with realloc().Julian Andres Klode
2012-06-16* apt-pkg/contrib/mmap.cc:Julian Andres Klode
- Fix the Fallback option to work correctly, by not calling realloc() on a map mapped by mmap(), and by using malloc and friends instead of new[].
2012-05-21* apt-pkg/contrib/mmap.cc:David Kalnischkies
- have a dummy SyncToFd around in case of ReadOnly access to a compressed file as we otherwise on Close() do not delete[] the char buffer but munmap() it… (Closes: #673815)
2012-01-18improve error reporting in case of errors in combination with zlibDavid Kalnischkies
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
2011-09-19use forward declaration in headers if possible instead of includesDavid 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
2011-05-13MAP_ANON is deprecated in favor of MAP_ANONYMOUS, but telesphoreo needsDavid Kalnischkies
to ships a patch for this so pretend to be nice and make it work (TM)
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
2011-02-12* apt-pkg/contrib/mmap.cc:David Kalnischkies
- do not try to free the mapping if its is unset
2010-07-09* doc/apt.conf.5.xml:David Kalnischkies
- add and document APT::Cache-{Start,Grow,Limit} options for mmap control
2010-07-08* apt-pkg/pkgcachegen.{cc,h}:David Kalnischkies
- make the used MMap moveable (and therefore dynamic resizeable) by applying (some) mad pointer magic (Closes: #195018)
2010-06-26make the MMap Grow Error a fatal one as while in theory the code shouldDavid Kalnischkies
never segfault it still tend to do it so better show it directly
2010-05-13* contrib/mmap.cc:David Kalnischkies
- clarify "MMap reached size limit" error message, thanks Ivan Masár!
2010-02-27* apt-pkg/contrib/mmap.{h,cc}:David Kalnischkies
- add char[] fallback for filesystems without shared writable mmap() like JFFS2. Thanks to Marius Vollmer for writing and to Loïc Minier for pointing to the patch! (Closes: #314334)
2009-11-09extent the mmap to be able to handle currently not implementedDavid Kalnischkies
(but planed) growable mmaps
2009-08-02* apt-pkg/contrib/mmap.cc:Julian Andres Klode
- Fix FTBFS on GNU/kFreeBSD by disabling DynamicMMap::Grow() on non-Linux architectures (as it uses mremap).
2009-07-26merge with lp:apt/debian-sidDavid Kalnischkies
Remove a bug (= an evil amok running if) introduced by the merge in 1817 which cause a segfault in the destructor for the dynamic mmap.
2009-07-24merge from the donkult branchMichael Vogt
2009-07-23[apt-pkg] yet another bit of mmap and pkgcachegen housekeepingDavid Kalnischkies
* add mmap error message also to the dynamic mmap * remove some more {Ver,Desc} == 0 checks in for loops * try to respect the given flags to the dynamic mmap * open cached caches not as ReadOnly and not as Shared, so we always have a copy of the cache in the memory we can modify (e.g. set the hold state on-the-fly)
2009-07-21The 'not dead yet' releaseMichael Vogt
* add hook for MarkInstall and MarkDelete (closes: #470035) * add the various foldmarkers in apt-pkg & cmdline (no code change) * versions with a pin of -1 shouldn't be a candidate (Closes: #355237) * prefer mmap as memory allocator in MMap instead of a static char array which can (at least in theory) grow dynamic * eliminate (hopefully all) segfaults in pkgcachegen.cc and mmap.cc which can arise if cache doesn't fit into the mmap (Closes: #535218) * display warnings instead of errors if the parts dirs doesn't exist * honor the dpkg hold state in new Marker hooks (closes: #64141)
2009-07-21eliminate (hopefully all) segfaults in pkgcachegen.cc and mmap.ccDavid Kalnischkies
which can arise if cache doesn't fit into the mmap (Closes: #535218) This removes also the previously introduced SegfaultSignalHandler: The handler works, but is ugly by design...
2009-07-08add a segfault handler to MMap to show the Cache-Limit message, whichDavid Kalnischkies
can be deactivated with MMap::SegfaultHandler=false (Closes: 535218)
2009-07-08[contrib/mmap] implements a theoretical dynamic growing mmapDavid Kalnischkies
based on Michael Vogts patch in #195018 this commit implements the use of mmap (as preferred) instead of a static char array. In theory this made it possible to grow the mmap as needed, but as it is currently impossible to move the mmap around in the memory the grow is likely to fail but it improve the memory usage a bit, so it is not totally useless for now - and maybe we can adjust the pointers in the future...
