Ævar Arnfjörð Bjarmason 228135d9ef pack-objects tests: don't leave test .git corrupt at end
Change the pack-objects tests to not leave their .git directory
corrupt and the end.

In 2fca19fbb5 ("fix multiple issues with t5300", 2010-02-03) a comment
was added warning against adding any subsequent tests, but since
4614043c8f ("index-pack: use streaming interface for collision test on
large blobs", 2012-05-24) the comment has drifted away from the code,
mentioning two test, when we actually have three.

Instead of having this warning let's just create a new .git directory
specifically for these tests.

As an aside, it would be interesting to instrument the test suite to
run a "git fsck" at the very end (in "test_done"). That would have
errored before this change, and may find other issues #leftoverbits.

Junio C Hamano 549ca8aa7c Merge branch 'jk/index-pack-maint'
"index-pack --strict" has been taught to make sure that it runs the
final object integrity checks after making the freshly indexed
packfile available to itself.

* jk/index-pack-maint:
  index-pack: correct install_packed_git() args

2018-06-13 12:50:46 -07:00
Jeff King 14a9bd2898 prepare_commit_graft: treat non-repository as a noop
The parse_commit_buffer() function consults lookup_commit_graft()
to see if we need to rewrite parents. The latter will look
at $GIT_DIR/info/grafts. If you're outside of a repository,
then this will trigger a BUG() as of b1ef400eec (setup_git_env:
avoid blind fall-back to ".git", 2016-10-20).

It's probably uncommon to actually parse a commit outside of
a repository, but you can see it in action with:

  cd /not/a/git/repo
  git index-pack --strict /some/file.pack

This works fine without --strict, but the fsck checks will
try to parse any commits, triggering the BUG(). We can fix
that by teaching the graft code to behave as if there are no
grafts when we aren't in a repository.

Arguably index-pack (and fsck) are wrong to consider grafts
at all. So another solution is to disable grafts entirely
for those commands. But given that the graft feature is
deprecated anyway, it's not worth even thinking through the
ramifications that might have.

There is one other corner case I considered here. What
should:

  cd /not/a/git/repo
  export GIT_GRAFT_FILE=/file/with/grafts
  git index-pack --strict /some/file.pack

do? We don't have a repository, but the user has pointed us
directly at a graft file, which we could respect. I believe
this case did work that way prior to b1ef400eec. However,
fixing it now would be pretty invasive. Back then we would
just call into setup_git_env() even without a repository.
But these days it actually takes a git_dir argument. So
there would be a fair bit of refactoring of the setup code
involved.

Given the obscurity of this case, plus the fact that grafts
are deprecated and probably shouldn't work under index-pack
anyway, it's not worth pursuing further. This patch at least
un-breaks the common case where you're _not_ using grafts,
but we BUG() anyway trying to even find that out.

Nguyễn Thái Ngọc Duy 43fa44fa3b pack-objects: move in_pack out of struct object_entry
Instead of using 8 bytes (on 64 bit arch) to store a pointer to a
pack. Use an index instead since the number of packs should be
relatively small.

This limits the number of packs we can handle to 1k. Since we can't be
sure people can never run into the situation where they have more than
1k pack files. Provide a fall back route for it.

If we find out they have too many packs, the new in_pack_by_idx[]
array (which has at most 1k elements) will not be used. Instead we
allocate in_pack[] array that holds nr_objects elements. This is
similar to how the optional in_pack_pos field is handled.

The new simple test is just to make sure the too-many-packs code path
is at least executed. The true test is running

    make test GIT_TEST_FULL_IN_PACK_ARRAY=1

to take advantage of other special case tests.

Fix a buggy warning about threads under NO_PTHREADS=YesPlease. Due to
re-using the delta_search_threads variable for both the state of the
"pack.threads" config & the --threads option, setting "pack.threads"
but not supplying --threads would trigger the warning for both
"pack.threads" & --threads.

Solve this bug by resetting the delta_search_threads variable in
git_pack_config(), it might then be set by --threads again and be
subsequently warned about, as the test I'm changing here asserts.

Add a test for the warning that's emitted when --threads or

The assertion for C_LOCALE_OUTPUT in the latter test is currently
redundant, since unlike index-pack the pack-objects warnings aren't
i18n'd. However they might be changed to be i18n'd in the future, and
there's no harm in future-proofing the test.

There's an existing bug in the implementation of pack-objects which
this test currently tests for as-is. Details about the bug & the fix

Jeff King 7176a31444 index-pack: complain when --stdin is used outside of a repo
The index-pack builtin is marked as RUN_SETUP_GENTLY,
because it's perfectly fine to index a pack in the
filesystem outside of any repository. However, --stdin mode
will write the result to the object database, which does not
make sense outside of a repository. Doing so creates a bogus
".git" directory with nothing in it except the newly-created
pack and its index.

Instead, let's flag this as an error and abort.

files from the name of .pack file, a copy-and-paste typo crept in,
mistakingly attempting to create and store the keep message file in
the .idx file we just created, instead of .keep file.

As we create the .keep file with O_CREAT|O_EXCL, and we do so after
we write the .idx file, we luckily do not clobber the .idx file, but
because we deliberately ignored EEXIST when creating .keep file
(which is justifiable because only the existence of .keep file
matters), nobody noticed this mistake so far.

Elia Pinto d6cd9ac905 t/t5300-pack-object.sh: use the $( ... ) construct for command substitution
The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.

The backquoted form is the traditional method for command
substitution, and is supported by POSIX.  However, all but the
simplest uses become complicated quickly.  In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.

The patch was generated by:

for _f in $(find . -name "*.sh")
do
	perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg'  "${_f}"
done

and then carefully proof-read.

As of the last commit, we can use "perl" instead of

This is not quite a mechanical s/$PERL_PATH/perl/

perl from a script we generate on the fly, and those scripts
do not have access to our internal shell functions. The
result can be double-checked by running:

few tests already actually use this variable when perl is needed. The
other test just call 'perl' and it might happen that the wrong perl

This becomes problematic on Windows, when the perl interpreter that is
compiled and installed on the Windows system is used, because this perl
interpreter might introduce some unexpected LF->CRLF conversions.

2009-02-25 14:50:05 -08:00
Junio C Hamano 6e180cdcec Make sure objects/pack exists before creating a new pack
In a repository created with git older than f49fb35 (git-init-db: create
"pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is
not created upon initialization.  It was Ok because subdirectories are
created as needed inside directories init-db creates, and back then,
packfiles were recent invention.

After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository.  This was exacerbated with
8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.

Many packfile related operations in such an old repository can fail
mysteriously because of this.

This commit introduces two helper functions to make things work better.

 - odb_mkstemp() is a specialized version of mkstemp() to refactor the
   code and teach it to create leading directories as needed;

 - odb_pack_keep() refactors the code to create a ".keep" file while
   create leading directories as needed.

reprepare_packed_git() is called. In practice this is hard to trigger
though.

Stephan Beyer d492b31caf t/: Use "test_must_fail git" instead of "! git"
This patch changes every occurrence of "! git" -- with the meaning
that a git call has to gracefully fail -- into "test_must_fail git".

This is useful to

 - make sure the test does not fail because of a signal,
   e.g. SIGSEGV, and

 - advertise the use of "test_must_fail" for new tests.

Jeff King e85fe4d85b more tr portability test script fixes
Dealing with NULs is not always safe with tr. On Solaris,
incoming NULs are silently deleted by both the System V and
UCB versions of tr. When converting to NULs, the System V
version works fine, but the UCB version silently ignores the
request to convert the character.

This patch changes all instances of tr using NULs to use
"perl -pe 'y///'" instead.

Junio C Hamano f2898cfadc unpack-objects: fix --strict handling
Earlier attempt (which was reverted) called added_object() (by the way,
the function should be renamed to resolve_dependents() --- it is called
when we have a complete object data, and is responsible to resolve pending
deltified objects that use this object as their delta base object) without
updating obj_list[nr].sha1 with the correct value.

Junio C Hamano c0e809e5c0 t5300: add test for "unpack-objects --strict"
This adds test for unpacking deltified objects with --strict option.

 - unpacking full trees with --strict should pass;

 - unpacking only trees with --strict should be rejected due to
   missing blobs;

 - unpacking only trees with --strict into an existing
   repository with necessary blobs should succeed.

Johannes Schindelin 2b84b5a874 Introduce the config variable pack.packSizeLimit
"git pack-objects" has the option --max-pack-size to limit the file
size of the packs to a certain amount of bytes.  On platforms where
the pack file size is limited by filesystem constraints, it is easy
to forget this option, and this option does not exist for "git gc"
to begin with.

So introduce a config variable to set the default maximum, but make
this overrideable by the command line.

Suggested by Tor Arvid Lund.

Junio C Hamano 41ac414ea2 Sane use of test_expect_failure
Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision.  Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:

    test_expect_{success,failure} 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        what is to be tested
    '

And expecting a failure exit from the whole sequence misses the
point of writing tests.  Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test.  The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.

This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:

    test_expect_success 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        ! this command should fail
    '

test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass.  So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:

    test_expect_failure 'git-foo should create bar' '
        rm -f bar &&
        git foo &&
        test -f bar
    '

This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

H.Merijn Brand 3175b0cfc1 the use of 'tr' in the test suite isn't really portable
Some versions of 'tr' only accept octal codes if entered with three digits,
and therefor misinterpret the '\0' in the test suite.

Some versions of 'tr' reject the (needless) use of character classes.
