The code to guess an output archive's format consumed any --format options and built a new one. Jonathan noticed that it does so in an unsafe way, risking to overflow the static buffer fmt_opt. Change the code to keep the existing --format options intact and to only add a new one if a format could be guessed based on the output file name. The new option is added as the first one, allowing the existing ones to overrule it, i.e. explicit --format options given on the command line win over format guesses, as before. To simplify the code further, format_from_name() is changed to return the full --format option, thus no potentially dangerous sprintf() calls are needed any more.

test_description='git tar-tree and git get-tar-commit-id test
|
|
|
|
This test covers the topics of file contents, commit date handling and
|
|
commit id embedding:
|
|
|
|
The contents of the repository is compared to the extracted tar
|
|
archive. The repository contains simple text files, symlinks and a
|
|
binary file (/bin/sh). Only paths shorter than 99 characters are
|
|
used.
|
|
|
|
git tar-tree applies the commit date to every file in the archive it
|
|
creates. The test sets the commit date to a specific value and checks
|
|
if the tar archive contains that value.
|
|
|
|
When giving git tar-tree a commit id (in contrast to a tree id) it
|
|
embeds this commit id into the tar archive as a comment. The test
|
|
checks the ability of git get-tar-commit-id to figure it out from the
|
|
tar file.
