In order for\nthis to succeed we need to first take out any randomness. Please\napply the patch at the end of the mail, which sets GIT_AUTHOR_DATE\nto a fixed value instead of using the current time, run the test\nand then this:\n\n $ md5sum t/trash/d.zip\t# run just after t5000-tar-tree.sh\n 35f6183b7816960cadfc6cac74530640 t/trash/d.zip\n\nThe test passes just fine here, so if the checksums match then your\nunzip is most likely to blame. In this case you can work around\nyour problem by commenting out the \"ln -s\" in t5000-tar-tree.sh.\n\nRené\n\n\n--- snip! ---\narchive: make test repeatable\n\nSet GIT_AUTHOR_DATE to a fixed value, just like it's already done\nfor GIT_COMMITTER_DATE. This makes the test repeatable, and\nresulting archive files can by compared on mailing lists simply by\ncomparing their checksums.\n\nSigned-off-by: Rene Scharfe \n\ndiff --git a/t/t5000-tar-tree.sh b/t/t5000-tar-tree.sh\nindex 42e28ab..f341451 100755\n--- a/t/t5000-tar-tree.sh\n+++ b/t/t5000-tar-tree.sh\n@@ -50,7 +50,7 @@ test_expect_success \\\n treeid=`git write-tree` &&\n echo $treeid >treeid &&\n git update-ref HEAD $(TZ=GMT GIT_COMMITTER_DATE=\"2005-05-27 22:00:00\" \\\n- git commit-tree $treeid wrote:\n> Well, looks OK to me at least.
