[Bug] git show crashes with deepened shallow clone

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just a quick report since I don't have time to bisect now (will do later
if no other gitster is faster...)

When I execute the below script 'git show' crashes. 'git log --oneline -2' gives
for example:

  3808bade5b76c4663ac4a3f751dc9f1ed0b08f2e three
  error: Could not read 1e8777edeb2b7e757f74c789e679fc6c71073897
  fatal: Failed to traverse parents of commit 0aa4ef86004f5bb29f67e971d7963f5cf430c668

gdb backtrace of one run is attached.
It happens on 32-bit Debian (5.0.10), 64-bit openSUSE (12.2), and Windows XP with git 1.8.4
on all systems.

The help of 'git fetch' says:

  --depth=<depth>

      Deepen or shorten the history of a shallow repository created by git clone with
      --depth=<depth> option (see git-clone(1)) to the specified number of commits from
      the tip of each remote branch history. Tags for the deepened commits are not fetched.
-------------------------------------------------------------------------------^^^^^^^^^

But that's not true. The tag 'two' (from the script below) gets fetched when
deepening the repository.



---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<
git init shallow-test &&
(cd shallow-test &&
echo foo > file &&
git add file &&
git commit -m"one"
git tag -m"one" one &&
echo bar >> file &&
git commit -m"two" file
git tag -m"two" two &&
echo baz >> file &&
git commit -m"three" file
git tag -m"three" three ) &&
git clone --depth=1 -b three file://`pwd`/shallow-test shallow-test-clone &&
(cd shallow-test-clone &&
git fetch --depth=2 &&
git log --oneline -2 ;
git show two)
