Code clean-up to adjust to a more recent lockfile API convention that
allows lockfile instances kept on the stack.
* ma/lockfile-cleanup:
lock_file: move static locks into functions
lock_file: make function-local locks non-static
refs.c: do not die if locking fails in `delete_pseudoref()`
refs.c: do not die if locking fails in `write_pseudoref()`
t/helper/test-write-cache: clean up lock-handling
|
|
Placing `struct lock_file`s on the stack used to be a bad idea, because
the temp- and lockfile-machinery would keep a pointer into the struct.
But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap,
2017-09-05), we can safely have lockfiles on the stack. (This applies
even if a user returns early, leaving a locked lock behind.)
Each of these `struct lock_file`s is used from within a single function.
Move them into the respective functions to make the scope clearer and
drop the staticness.
For good measure, I have inspected these sites and come to believe that
they always release the lock, with the possible exception of bailing out
using `die()` or `exit()` or by returning from a `cmd_foo()`.
As pointed out by Jeff King, it would be bad if someone held on to a
`struct lock_file *` for some reason. After some grepping, I agree with
his findings: no-one appears to be doing that.
After this commit, the remaining occurrences of "static struct
lock_file" are locks that are used from within different functions. That
is, they need to remain static. (Short of more intrusive changes like
passing around pointers to non-static locks.)

We have several callers like
if (active_cache_changed && write_locked_index(...))
handle_error();
rollback_lock_file(...);
where the final rollback is needed because "!active_cache_changed"
shortcuts the if-expression. There are also a few variants of this,
including some if-else constructs that make it more clear when the
explicit rollback is really needed.
Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and
simplify the callers. Leave the most complicated of the callers (in
builtin/update-index.c) unchanged. Rewriting it to use this new flag
would end up duplicating logic.
We could have made the new flag behave the other way round
("FORCE_WRITE"), but that could break existing users behind their backs.
Let's take the more conservative approach. We can still migrate existing
callers to use our new flag. Later we might even be able to flip the
default, possibly without entirely ignoring the risk to in-flight or
out-of-tree topics.

Our code often opens a path to an optional file, to work on its
contents when we can successfully open it. We can ignore a failure
to open if such an optional file does not exist, but we do want to
report a failure in opening for other reasons (e.g. we got an I/O
error, or the file is there, but we lack the permission to open).
The exact errors we need to ignore are ENOENT (obviously) and
ENOTDIR (less obvious). Instead of repeating comparison of errno
with these two constants, introduce a helper function to do so.
* jc/noent-notdir:
treewide: use is_missing_file_error() where ENOENT and ENOTDIR are checked
compat-util: is_missing_file_error()
|
|
Using the is_missing_file_error() helper introduced in the previous
step, update all hits from
$ git grep -e ENOENT --and -e ENOTDIR
There are codepaths that only check ENOENT, and it is possible that
some of them should be checking both. Updating them is kept out of
this step deliberately, as we do not want to change behaviour in this
step.

"git rm" used to refuse to remove a submodule when it has its own
git repository embedded in its working tree. It learned to move
the repository away to $GIT_DIR/modules/ of the superproject
instead, and allow the submodule to be deleted (as long as there
will be no loss of local modifications, that is).
* sb/submodule-rm-absorb:
rm: absorb a submodules git dir before deletion
submodule: rename and add flags to ok_to_remove_submodule
submodule: modernize ok_to_remove_submodule to use argv_array
submodule.h: add extern keyword to functions
|
|
When deleting a submodule, we need to keep the actual git directory around,
such that we do not lose local changes in there and at a later checkout
of the submodule we don't need to clone it again.
Now that the functionality is available to absorb the git directory of a
submodule, rewrite the checking in git-rm to not complain, but rather
relocate the git directories inside the superproject.
An alternative solution was discussed to have a function
`depopulate_submodule`. That would couple the check for its git directory
and possible relocation before the the removal, such that it is less
likely to miss the check in the future. But the indirection with such
a function added seemed also complex. The reason for that was that this
possible move of the git directory was also implemented in
`ok_to_remove_submodule`, such that this function could truthfully
answer whether it is ok to remove the submodule.
The solution proposed here defers all these checks to the caller.

In different contexts the question "Is it ok to delete a submodule?"
may be answered differently.
In 293ab15eea (submodule: teach rm to remove submodules unless they
contain a git directory, 2012-09-26) a case was made that we can safely
ignore ignored untracked files for removal as we explicitely ask for the
removal of the submodule.
In a later patch we want to remove submodules even when the user doesn't
explicitly ask for it (e.g. checking out a tree-ish in which the submodule
doesn't exist). In that case we want to be more careful when it comes
to deletion of untracked files. As of this patch it is unclear how this
will be implemented exactly, so we'll offer flags in which the caller
can specify how the different untracked files ought to be handled.
As the flags allow the function to not die on an error when spawning
a child process, we need to find an appropriate return code for the
case when the child process could not be started. As in that case we
cannot tell if the submodule is ok to remove, we'd want to return 'false'.
As only 0 is understood as false, rename the function to invert the
meaning, i.e. the return code of 0 signals the removal of the submodule
is fine, and other values can be used to return a more precise answer
what went wrong.

Callers of the hold_locked_index() function pass 0 when they want to
prepare to write a new version of the index file without wishing to
die or emit an error message when the request fails (e.g. somebody
else already held the lock), and pass 1 when they want the call to
die upon failure.
This option is called LOCK_DIE_ON_ERROR by the underlying lockfile
API, and the hold_locked_index() function translates the paramter to
LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update().
Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop
translating. Callers other than the ones that are replaced with
this change pass '0' to the function; no behaviour change is
intended with this patch.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
---
Among the callers of hold_locked_index() that passes 0:
- diff.c::refresh_index_quietly() at the end of "git diff" is an
opportunistic update; it leaks the lockfile structure but it is
just before the program exits and nobody should care.
- builtin/describe.c::cmd_describe(),
builtin/commit.c::cmd_status(),
sequencer.c::read_and_refresh_cache() are all opportunistic
updates and they are OK.
- builtin/update-index.c::cmd_update_index() takes a lock upfront
but we may end up not needing to update the index (i.e. the
entries may be fully up-to-date), in which case we do not need to
issue an error upon failure to acquire the lock. We do diagnose
and die if we indeed need to update, so it is OK.
- wt-status.c::require_clean_work_tree() IS BUGGY. It asks
silence, does not check the returned value. Compare with
callsites like cmd_describe() and cmd_status() to notice that it
is wrong to call update_index_if_able() unconditionally.

When cache_entry structs are removed from index_state.cache, they are not
properly freed. Freeing those entries wasn't possible before because we
couldn't remove them from index_state.name_hash.
Now that we _do_ remove the entries from name_hash, we can also free them.
Add 'free(cache_entry)' to all call sites of name-hash.c::remove_name_hash
in read-cache.c (we could free() directly in remove_name_hash(), but
name-hash.c isn't concerned with cache_entry allocation at all).
Accessing a cache_entry after removing it from the index is now no longer
allowed, as the memory has been freed. The following functions need minor
fixes (typically by copying ce->name before use):
- builtin/rm.c::cmd_rm
- builtin/update-index.c::do_reupdate
- read-cache.c::read_index_unmerged
- resolve-undo.c::unmerge_index_entry_at

As of 7612a1efdb (2006-06-09 git-rm: honor -n flag.) the variable
'pathspec' seems to be assumed to be never NULL after calling get_pathspec
There was a NULL pointer check after the seen = NULL assignment, which
was removed by that commit. So if pathspec would be NULL now, we'd segfault
in the line accessing the pathspec:
for (i = 0; pathspec[i] ; i++)
A few lines later, 'pathspec' still cannot be NULL, but that check was
overlooked, hence removing it now.
As the null pointer check was removed, it makes no sense to assign NULL
to seen and 3 lines later another value as there are no conditions in
between.

Currently using "git rm" on a submodule removes the submodule's work tree
from that of the superproject and the gitlink from the index. But the
submodule's section in .gitmodules is left untouched, which is a leftover
of the now removed submodule and might irritate users (as opposed to the
setting in .git/config, this must stay as a reminder that the user showed
interest in this submodule so it will be repopulated later when an older
commit is checked out).
Let "git rm" help the user by not only removing the submodule from the
work tree but by also removing the "submodule.<submodule name>" section
from the .gitmodules file and stage both. This doesn't happen when the
"--cached" option is used, as it would modify the work tree. This also
silently does nothing when no .gitmodules file is found and only issues a
warning when it doesn't have a section for this submodule. This is because
the user might just use plain gitlinks without the .gitmodules file or has
already removed the section by hand before issuing the "git rm" command
(in which case the warning reminds him that rm would have done that for
him). Only when .gitmodules is found and contains merge conflicts the rm
command will fail and tell the user to resolve the conflict before trying
again.
Also extend the man page to inform the user about this new feature. While
at it promote the submodule sub-section to a chapter as it made not much
sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM".
In t7610 three uses of "git rm submod" had to be replaced with "git rm
--cached submod" because that test expects .gitmodules and the work tree
to stay untouched. Also in t7400 the tests for the remaining settings in
the .gitmodules file had to be changed to assert that these settings are
missing.
