The new tests were not taking core.filemode into account when
testing file modes after repo initialization. Fixed that and some
other Windows warnings that have crept in.
The cppcheck static analyzer generates warnings for a bunch of
places in the libgit2 code base. All the ones fixed in this
commit are actually false positives, but I've reorganized the
code to hopefully make it easier for static analysis tools to
correctly understand the structure. I wouldn't do this if I
felt like it was making the code harder to read or worse for
humans, but in this case, these fixes don't seem too bad and will
hopefully make it easier for better analysis tools to get at any
real issues.
A leading slash confuses the name normalization code when the flags
include ALLOW_ONELEVEL. Catch this case in particular to avoid
triggering an assertion in the uppercase check which expects us not to
pass it an empty string.
The existing tests don't catch this as they simply use the NORMAL
flag.
This fixes#1300.
I saw a repo in the wild today which had a master branch ref which was packed, but had no trailing newline. Git handled it fine, but libgit2 choked on it. Fix seems simple enough. If we don't see a newline, assume the end of the buffer is the end of the ref line.
When normalizing a reference name, if there is an error because
the name is invalid, then the memory allocated for storing the
name could be leaked if the caller was not careful and assumed
that the error return code meant that no allocation had occurred.
This fixes that by explicitly deallocating the reference name
buffer if there is an error in normalizing the name.
* Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing
combinations of flags
* Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that
are left empty after removal
* Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file,
not a dir (previously an EEXISTS error was ignored, even for
files) and enable this flag for git_futils_mkpath2file call
* Improve accuracy of error messages from git_futils_mkdir
This improves docs in some of the public header files, cleans
up and improves some of the example code, and fixes a couple
of pedantic warnings in places.
This adds a new API that allows users to reload the config if the
file has changed on disk. A new config callback function to
refresh the config was added.
The modified time and file size are used to test if the file needs
to be reloaded (and are now stored in the disk backend object).
In writing tests, just using mtime was a problem / race, so I
wanted to check file size as well. To support that, I extended
`git_futils_readbuffer_updated` to optionally check file size in
addition to mtime, and I added a new function `git_filebuf_stats`
to fetch the mtime and size for an open filebuf (so that the
config could be easily refreshed after a write).
Lastly, I moved some similar file checking code for attributes
into filebuf. It is still only being used for attrs, but it
seems potentially reusable, so I thought I'd move it over.
We used to require loose references to contain only an OID (possibly
after trimming the string). This is however not enough for letting us
lookup FETCH_HEAD, which can have a lot of content after the initial
OID.
Change the parsing rules so that a loose refernce must e at least 40
bytes long and the 41st (if it's there) must be accepted by
isspace(3). This makes the trim unnecessary, so only do it for
symrefs. This fixes#977.
This started as a complex new test for checkout going through the
"typechanges" test repository, but that revealed numerous issues
with checkout, including:
* complete failure with submodules
* failure to create blobs with exec bits
* problems when replacing a tree with a blob because the tree
"example/" sorts after the blob "example" so the delete was
being processed after the single file blob was created
This fixes most of those problems and includes a number of other
minor changes that made it easier to do that, including improving
the TYPECHANGE support in diff/status, etc.
Indicate whether the error comes from the ref already existing or
elsewhere. We always perform the check and this lets the user write
more concise code.
This refactors the diff output code so that an iterator object
can be used to traverse and generate the diffs, instead of just
the `foreach()` style with callbacks. The code has been rearranged
so that the two styles can still share most functions.
This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses
that as a common error code for marking the end of iteration when
using a iterator style of object.
This updates all the `foreach()` type functions across the library
that take callbacks from the user to have a consistent behavior.
The rules are:
* A callback terminates the loop by returning any non-zero value
* Once the callback returns non-zero, it will not be called again
(i.e. the loop stops all iteration regardless of state)
* If the callback returns non-zero, the parent fn returns GIT_EUSER
* Although the parent returns GIT_EUSER, no error will be set in
the library and `giterr_last()` will return NULL if called.
This commit makes those changes across the library and adds tests
for most of the iteration APIs to make sure that they follow the
above rules.
