* python scripts: pep8ize codebaseRichard Maw2012-08-011-27/+28
| | | | | | | | | This was done with the aid of the pep8 script, available by running `easy_install pep8`. It may be worth making this part of ./check, but that will require putting pep8 into the development tools stratum. This should be easy, given pep8 has no external dependencies.
* unit tests: add tests for tarball extractionRichard Maw2012-07-051-1/+1

* Normalize timestamps without filesystem operationsLars Wirzenius2012-06-291-4/+9
| | | | | | | This changes the timestamp in the Python tarfile.TarInfo data structure rather than setting the timestamp in the filesystem. Suggested by Richard Maw.
* Normalize timestamps of files in chunk artifactsLars Wirzenius2012-06-281-0/+9
| | | | | | | This avoids problems with clock skew between the machine that built an artifact and the machine the uses it. I ran into this problem during a test build of other changes in this patch series. We have seen it before, now it is fixed.
* morphlib.bins: remove create_stratumRichard Maw2012-06-141-8/+0
| | | | create_stratum is no longer used, since strata are now chunk lists
* morph: remove dead code and replace Execute with app.runcmdRichard Maw2012-05-301-2/+2
|
* bins: move errno from stagingareaRichard Maw2012-05-151-0/+1
| | | | | This import was forgotten when the artifact extract code was moved into bins, so it could be used in builder
* builder: use the same tar extract logic for all artifactsRichard Maw2012-05-141-10/+81
| | | | | Before only the staging area had symbolic links handled, now strata and systems will have the same logic.
* Fix minor problemsLars Wirzenius2012-04-181-1/+1
|
* Add a way to unpack a tar file from an open file handleLars Wirzenius2012-04-181-0/+12
|
* tar: add -h option to extractionRichard Maw2012-03-161-1/+1
| | | | | | This should stop tar from replacing symbolic links with directories and instead follow the symbolic links, extracting the files into the linked directories
* Test for and include dirnames in chunks the same as filenamesLars Wirzenius2012-03-061-3/+1
|
* Create chunks, strata in cache via temporary filesLars Wirzenius2012-02-271-8/+10
| | | | | This avoids problems with files with the right names but partial content, if morph is killed in the middle of writing the file.
* Bump copyright years, get rid of long lines and unused imports.Jannis Pohlmann2012-01-231-4/+1

* stop morph from using fakeroot and sudoLars Wirzenius2012-01-111-7/+3
| | | | | | | | | | | | | Instead, assume the whole build will be run, by the user, under fakeroot or sudo (the latter for system image builds). This allows us to run all non-system-image-build tests without root access at all. We now always create the cache directory, if missing, even if we're running as root. We no longer run ldconfig if ld.so.conf is missing. It is missing during our tests, but is (now) created by fhs-dirs for real builds.
* use tarfile againLars Wirzenius2011-12-141-10/+5
| | | | | Busybox tar is incapable of doing this, so we have to use Python's tarlib, at least for now.
* Made some sudo commands into fakeroot commandsRichard Maw2011-12-081-14/+14
| | | | | | | | | | | | | | | | | | | | Some commands can remain as fakeroot if they share the same fakeroot This can be done with the -i and -s parameters to fakeroot Now the Execute objects contain a reference to the file that stores their state, so fake commands' fake state is recognised by later commands The creating a system image definitely needs to be sudo though. Morph needs to create some files as part of the process, so unfortunately the equivalent to 'echo foo | sudo tee bar >/dev/null' is being used. They could be created with sufficient permissions, written then have better permissions set, but it seemed neater this way A better solution may be to have a subprogram that does the system image creation Putting files into the staging area for building other chunks is currently sudo, but shouldn't have to be. Rather than having a fakeroot per Execute object, it may be better to have a global one, though this would prevent concurrent use of fakeroot.
* Make the install parts of morphs run as sudoRichard Maw2011-12-081-3/+6
| | | | | | | | Then fix all the places where this broke things because they didn't have the required permissions. This is a potential security risk of course, it would be preferable if the install commands were run in a fakeroot session and only the final image building was run as root, but it needs to work first
* use external tar toolLars Wirzenius2011-12-061-10/+13
| | | | This saves a bunch of memory use.
* add memory profiling to create_chunkLars Wirzenius2011-12-061-2/+8
|
* use system tar instead of Python's tarfile library to extract tarballsLars Wirzenius2011-11-301-3/+2
|
* Fix chunk building to deal correctly with symlinks to directoriesLars Wirzenius2011-11-141-4/+10
|
* Combine unpack_chunk and unpack_stratum into unpack_binaryLars Wirzenius2011-11-031-17/+4
|
* Output multiple chunks when requestedLars Wirzenius2011-11-031-1/+2
|
* Include only files matching regexps, removes them from after adding themLars Wirzenius2011-11-031-4/+53
|
* Add tests for create_chunk's glob handlingLars Wirzenius2011-11-031-1/+1

* Add functions for creating and unpacking strata.Lars Wirzenius2011-10-171-0/+22
