2021-03-11archive: expand only a single %(describe) per archiveLibravatar René Scharfe1-0/+14
Every %(describe) placeholder in $Format:...$ strings in files with the attribute export-subst is expanded by calling git describe. This can potentially result in a lot of such calls per archive. That's OK for local repositories under control of the user of git archive, but could be a problem for hosted repositories. Expand only a single %(describe) placeholder per archive for now to avoid denial-of-service attacks. We can make this limit configurable later if needed, but let's start out simple.

2017-09-14archive: don't add empty directories to archivesLibravatar René Scharfe1-1/+1
While git doesn't track empty directories, git archive can be tricked into putting some into archives. One way is to construct an empty tree object, as t5004 does. While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild. Another way is using the literal name of a directory in an exclude pathspec -- its contents are are excluded, but the directory stub is included. That's inconsistent: exclude pathspecs containing wildcards don't leave empty directories in the archive. Yet another way is have a few levels of nested subdirectories (e.g. d1/d2/d3/file1) and ignoring the entries at the leaves (e.g. file1). The directories with the ignored content are ignored as well (e.g. d3), but their empty parents are included (e.g. d2). As empty directories are not supported by git, they should also not be written into archives. If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it. There already is a mechanism in place for suppressing empty directories. When read_tree_recursive() encounters a directory excluded by a pathspec then it enters it anyway because it might contain included entries. It calls the callback function before it is able to decide if the directory is actually needed. For that reason git archive adds directories to a queue and writes entries for them only when it encounters the first child item -- but currently only if pathspecs with wildcards are used. Queue *all* directories, no matter if there even are pathspecs present. This prevents git archive from writing entries for empty directories in all cases.

2017-08-19archive: don't queue excluded directoriesLibravatar René Scharfe1-2/+2
Reject directories with the attribute export-ignore already while queuing them. This prevents read_tree_recursive() from descending into them and this avoids write_archive_entry() rejecting them later on, which queue_or_write_archive_entry() is not prepared for. Borrow the existing strbuf to build the full path to avoid string copies and extra allocations; just make sure we restore the original value before moving on. Keep checking any other attributes in write_archive_entry() as before, but avoid checking them twice. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-19t5001: add tests for export-ignore attributes and exclude pathspecsLibravatar René Scharfe1-3/+44
Demonstrate mishandling of the attribute export-ignore by git archive when used together with pathspecs. Wildcard pathspecs can even cause it to abort. And a directory excluded without a wildcard is still included as an empty folder in the archive.

2014-06-04t5000, t5003: do not use test_cmp to compare binary filesLibravatar Stepan Kasal1-1/+1
test_cmp() is primarily meant to compare text files (and display the difference for debug purposes). Raw "cmp" is better suited to compare binary files (tar, zip, etc.). On MinGW, test_cmp is a shell function mingw_test_cmp that tries to read both files into environment, stripping CR characters (introduced in commit 4d715ac0). This function usually speeds things up, as fork is extremly slow on Windows. But no wonder that this function is extremely slow and sometimes even crashes when comparing large tar or zip files.

2013-11-12tar-tree: remove deprecated commandLibravatar John Keeping1-10/+0
"git tar-tree" has been a thin wrapper around "git archive" since commit fd88d9c (Remove upload-tar and make git-tar-tree a thin wrapper to git-archive, 2006-09-24), which also made it print a message indicating that git-tar-tree is deprecated.

2011-09-27archive.c: use OPT_BOOL()Libravatar Junio C Hamano1-0/+9
The list variable (which is OPT_BOOLEAN) is initialized to 0 and only checked against 0 in the code, so it is safe to use OPT_BOOL(). The worktree_attributes variable (which is OPT_BOOLEAN) is initialized to 0 and later assigned to a field with the same name in struct archive_args, which is a bitfield of width 1. It is safe and even more correct to use OPT_BOOL() here; the new test in 5001 demonstrates why using OPT_COUNTUP is wrong. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-07-27archive: abbreviate substituted commit ids againLibravatar Jonathan Nieder1-1/+1
Given a file with: (define archive-id "$Format:%ct|%h|a$") and an export-subst attribute, the "%h" results in an full 40-digit object name instead of the expected 7-digit one. The export-subst feature requests unabbreviated object names because that is the low-level default. The effect was not observable until v1.7.1.1~17^2~3 (2010-05-03), which taught log --format=%h to respect the --abbrev option.
