2018-05-24import-tars: read overlong names from pax extended headerLibravatar Pedro Alvarez Piedehierro1-2/+29
Importing gcc tarballs[1] with import-tars script (in contrib) fails when hitting a pax extended header. Make sure we always read the extended attributes from the pax entries, and store the 'path' value if found to be used in the next ustar entry. The code to parse pax extended headers was written consulting the Pax Pax Interchange Format documentation [2].

2016-08-03import-tars: support hard linksLibravatar Johannes Schindelin1-11/+20
Previously, we simply treated hard links as if they were plain files with size 0, ignoring the link type "1" and hence the link target. What we should do instead, of course, is to use the link target to get at the import mark for the contents, even if we cannot recreate the hard link per se, as Git has no concept of hard links.

2009-09-03import-tars: Allow per-tar author and commit message.Libravatar Peter Krefting1-4/+46
If the "--metainfo=<ext>" option is given on the command line, a file called "<filename.tar>.<ext>" will be used to create the commit message for "<filename.tar>", instead of using "Imported from filename.tar". The author and committer of the tar ball can also be overridden by embedding an "Author:" or "Committer:" header in the metainfo file.

2009-03-20import-tars: separate author from committerLibravatar Giuseppe Bilotta1-5/+11
The import-tars script is typically employed to (re)create the past history of a project from stored tars. Although assigning authorship in these cases can be a somewhat arbitrary process, it makes sense to set the author to whoever created the tars in the first place (if it's known), and (s)he can in general be different from the committer (whoever is running the script). Implement this by having separate author and committer data, making them settable from the usual GIT_* environment variables. Acked-by: Shawn O.

2007-05-16import-tars: Use the "Link indicator" to identify directoriesLibravatar Johannes Schindelin1-1/+1
Earlier, we used the mode to determine if a name was associated with a directory. This fails, since some tar programs do not set the mode correctly. However, the link indicator _has_ to be set correctly. Noticed by Chris Riddoch.

* maint: Fix documentation of tag in git-fast-import.txt Properly handle '0' filenames in import-tars
2007-05-07Properly handle '0' filenames in import-tarsLibravatar Shawn O. Pearce1-1/+1
Randal L. Schwartz pointed out multiple times that we should be testing the length of the name string here, not if it is "true". The problem is the string '0' is actually false in Perl when we try to evaluate it in this context, as '0' is 0 numerically and the number 0 is treated as a false value. This would cause us to break out of the import loop early if anyone had a file or directory named "0". Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

* gfi-maint: Teach import-tars about GNU tar's @LongLink extension.
2007-05-02Teach import-tars about GNU tar's @LongLink extension.Libravatar Johannes Schindelin1-0/+19
This extension allows GNU tar to process file names in excess of the 100 characters defined by the original tar standard. It does this by faking a file, named '././@LongLink' containing the true file name, and then adding the file with a truncated name. The idea is that tar without this extension will write out a file with the long file name, and write the contents into a file with truncated name. Unfortunately, GNU tar does a lousy job at times. When truncating results in a _directory_ name, it will happily use _that_ as a truncated name for the file. An example where this actually happens is gcc-4.1.2, where the full path of the file WeThrowThisExceptionHelper.java truncates _exactly_ before the basename. So, we have to support that ad-hoc extension. This bug was noticed by Chris Riddoch on IRC. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Shawn O.

2007-02-08tar archive frontend for fast-import.Libravatar Shawn O. Pearce1-0/+105
This is an example fast-import frontend, in less than 100 lines of Perl. It accepts one or more tar archives on the command line, passes them through gzcat/bzcat/zcat if necessary, parses out the individual file headers and feeds all contained data to fast-import. No temporary files are involved. Each tar is treated as one commit, with the commit timestamp coming from the oldest file modification date found within the tar. Each tar is also tagged with an annotated tag, using the basename of the tar file as the name of the tag. Currently symbolic links and hard links are not handled by the importer. The file checksums are also not verified. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
