The structinit tests don't make sense unless structure padding
is uniformly initialized, which is unlikely to happen on release
builds. Only enable them for DEBUG builds. Further, rename them
to core::structinit.
On case insensitive filesystems, we may have files in the working
directory that case fold to a name we want to write. Remove those
files (by default) so that we will not end up with a filename that
has the unexpected case.
The documentation for `git_path_join_unrooted` states that the base
length will be returned, so that consumers like checkout know where
to start creating directories instead of always creating directories
at the directory root.
The implementation of the hashsig API disallows computing a signature on
small files containing only a few lines. This new flag disables this
behavior.
git_diff_find_similar() sets this flag by default which means that rename
/ copy detection of small files will now work. This in turn affects the
behavior of the git_status and git_blame APIs which will now detect rename
of small files assuming the right options are passed.
Remove the hook symlink from the test resources, so that we can
have a source tree that is easy to zip up and copy around on systems
that don't support symlinks. Create it dynamically at test execution
instead.
On a case-insensitive filesystem, we need to deal with case-changing
renames (eg, foo -> FOO) by removing the old and adding the new,
exactly as if we were on a case-sensitive filesystem.
Update the `checkout::tree::can_cancel_checkout_from_notify` test, now
that notifications are always sent case sensitively.
This introduces the functionality of submodule update in
'git_submodule_do_update'. The existing 'git_submodule_update' function is
renamed to 'git_submodule_update_strategy'. The 'git_submodule_update'
function now refers to functionality similar to `git submodule update`,
while `git_submodule_update_strategy` is used to get the configured value
of submodule.<name>.update.
Path validation may be influenced by `core.protectHFS` and
`core.protectNTFS` configuration settings, thus treebuilders
can take a repository to influence their configuration.
HFS filesystems ignore some characters like U+200C. When these
characters are included in a path, they will be ignored for the
purposes of comparison with other paths. Thus, if you have a ".git"
folder, a folder of ".git<U+200C>" will also match. Protect our
".git" folder by ensuring that ".git<U+200C>" and friends do not match it.
Disallow:
1. paths with trailing dot
2. paths with trailing space
3. paths with trailing colon
4. paths that are 8.3 short names of .git folders ("GIT~1")
5. paths that are reserved path names (COM1, LPT1, etc).
6. paths with reserved DOS characters (colons, asterisks, etc)
These paths would (without \\?\ syntax) be elided to other paths - for
example, ".git." would be written as ".git". As a result, writing these
paths literally (using \\?\ syntax) makes them hard to operate with from
the shell, Windows Explorer or other tools. Disallow these.
When turning UTF-8 paths into UCS-2 paths for Windows, always use
the \\?\-prefixed paths. Because this bypasses the system's
path canonicalization, handle the canonicalization functions ourselves.
We must:
1. always use a backslash as a directory separator
2. only use a single backslash between directories
3. not rely on the system to translate "." and ".." in paths
4. remove trailing backslashes, except at the drive root (C:\)
We do not currently generate any messages when we're counting the
objects, as might be expected from a local upload-pack. Assert that we
do call the function when working.
This option does not get persisted to disk, which makes it different
from the rest of the setters. Remove it until we go all the way.
We still respect the configuration option, and it's still possible to
perform a one-time prune by calling the function.
This is hiding a bug in the prune code, whereby we prune references we
shouldn't but don't notice it in the code afterwards because
update_tips() recreates them.
This means that we do perform changes to the references (and get rid of
the reflogs) when we shouldn't.
Given
top
!top/foo
in an ignore file, we should not unignore top/foo. This is an
implementation detail of the git code leaking, but that's the behaviour
we should show.
A negation rule can only negate an exact rule it has seen before.
There are some combination of objects and target types which we know
cannot be fulfilled. Return EINVALIDSPEC for those to signify that there
is a mismatch in the user-provided data and what the object model is
capable of satisfying.
If we start at a tag and in the course of peeling find out that we
cannot reach a particular type, we return EPEEL.
This is a contract that we made in the library and that we need to uphold. The
contents of a blob can never be NULL because several parts of the library (including
the filter and attributes code) expect `git_blob_rawcontent` to always return a
valid pointer.
When we fetch twice with the same remote object, we did not properly
clear the connection flags, so we would leak state from the last
connection.
This can cause the second fetch with the same remote object to fail if
using a HTTP URL where the server redirects to HTTPS, as the second
fetch would see `use_ssl` set and think the initial connection wanted to
downgrade the connection.
When creating a new remote, contrary to loading one from disk,
active_refspecs was not populated. This means that if using the new
remote to push, git_push_update_tips() will be a no-op since it
checks the refspecs passed during the push against the base ones
i.e. active_refspecs. And therefore the local refs won't be created
or updated after the push operation.
There is one well-known and well-tested parser which we should use,
instead of implementing parsing a second time.
The common parser is also augmented to copy the LHS into the RHS if the
latter is empty.
The expressions test had to change a bit, as we now catch a bad RHS of a
refspec locally.
We have the step-by-step method in the initialization function as we
want to remove references based on the list of references which are
already there, and we can use the convenience function for testing the
main push.
This function, similar in style to git_remote_fetch(), performs all the
steps required for a push, with a similar interface.
The remote callbacks struct has learnt about the push callbacks, letting
us set the callbacks a single time instead of setting some in the remote
and some in the push operation.
This describes their purpose better, as we now initialize ssl and some
other global stuff in there. Calling the init function is not something
which has been optional for a while now.
git hardocodes these as objects which exist regardless of whether they
are in the odb and uses them in the shell interface as a way of
expressing the lack of a blob or tree for one side of e.g. a diff.
In the library we use each language's natural way of declaring a lack of
value which makes a workaround like this unnecessary. Since git uses it,
it does however mean each shell application would need to perform this
check themselves.
This makes it common work across a range of applications and an issue
with compatibility with git, which fits right into what the library aims
to provide.
Thus we introduce the hard-coded empty blob and tree in the odb
frontend. These hard-coded objects are checked for before going to the
backends, but after the cache check, which means the second time they're
used, they will be treated as normal cached objects instead of creating
new ones.
If the remote is anonymous, then we cannot check for any configuration,
as there is no name. Check for this before we try to use the name, which
may be a NULL pointer.
This fixes#2697.
This function has one output but can match multiple files, which can be
unexpected for the user, which would usually path the exact path of the
file he wants the status of.
We cannot know from looking at .gitmodules whether a directory is a
submodule or not. We need the index or tree we are comparing against to
tell us. Otherwise we have to assume the entry in .gitmodules is stale
or otherwise invalid.
Thus we pass the index of the repository into the workdir iterator, even
if we do not want to compare against it. This follows what git does,
which even for `git diff <tree>`, it will consider staged submodules as
such.
We consider an entry in .gitmodules to mean that we have a submodule at
a particular path, even if HEAD^{tree} and the index do not contain any
reference to it.
We should ignore that submodule entry and simply consider that path to
be a regular directory.
We currently consider CR to start the end of the line, but that means
that we miss cases with CR CR LF which can be used with git to match
files whose names have CR at the end of their names.
The fix from the patch comes from Russell's comment in the issue.
This fixes#2536.
* Error-handling is cleaned up to only let a file-not-found error
through, not other sorts of errors. And when a file-not-found
error happens, we clean up the error.
* Test now checks that file-not-found introduces no error. And
other minor cleanups.
An anonymous remote wouldn't create remote-tracking branches, so testing
we don't create them for TAGS_ALL is nonsensical. Furthermore, the name
of the supposed remote-tracking branch was also not one which would have
been created had it had a name.
Give the remote a name and test that we only create the tags when we
pass TAGS_ALL and that we do create the remote-branch branch when given
TAGS_AUTO.
When we update FETCH_HEAD we check whether the remote is the current
branch's upstream remote. The code does not check whether the current
refspec is relevant for this reference but always tries to perform the
reverse transformation, which causes it to error out if the refspec
doesn't match the reference.
Thanks to Pierre-Olivier Latour for the reproduction recipe.
For example, if you have
[include]
path = foo
and foo didn't exist, git_config_open_ondisk() would just give up
on the rest of the file. Now it ignores the unresolved include
without error and continues reading the rest of the file.
Already cherry-picked commits should not be re-included. If all changes
included in a commit exist in the upstream, then we should error with
GIT_EAPPLIED.
`git_rebase_next` will apply the next patch (or cherry-pick)
operation, leaving the results checked out in the index / working
directory so that consumers can resolve any conflicts, as appropriate.
