This is quite close to running "git for-each-ref" except:
1. It does not take any formatting or selection options at
all.
2. The output is not sorted.
I wrote it to look at debugging some issues with ref
iteration, but there's no reason it can't live on as an
example command.
This takes the `--stat` and related example options in the example
diff.c program and converts them to use the `git_diff_get_stats`
API which nicely formats stats for you.
I went to add bar-graph scaling to the stats formatter and noticed
that the `git_diff_stats` structure was holding on to all of the
`git_patch` objects. Unfortunately, each of these objects keeps
the full text of the diff in memory, so this is very expensive. I
ended up modifying `git_diff_stats` to keep just the data that it
needs to keep and allowed it to release the patches. Then, I added
width scaling to the output on top of that.
In making the diff example program match 'git diff' output, I ended
up removing an newline from the sumamry output which I then had to
compensate for in the email formatting to match the expectations.
Lastly, I went through and refactored the tests to use a couple of
helper functions and reduce the overall amount of code there.
I was playing with "git diff-index" and wanted to be able to
emulate that behavior a little more closely with the diff example.
Also, I wanted to play with running `git_diff_tree_to_workdir`
directly even though core Git doesn't exactly have the equivalent,
so I added a command line option for that and tweaked some other
things in the example code.
This changes a minor output thing in that the "raw" print helper
function will no longer add ellipses (...) if the OID is not
actually abbreviated.
This allows you to use a --repeat option to run status over and
over and see how the output changes as you make local directory
changes without reopening the git_repository object each time.
Also, adds a flag to explicitly list the submodules before status.
The order in this function is the opposite to what
create_with_fetchspec() has, so change this one, as url-then-refspec is
what git does.
As we need to break compilation and the swap doesn't do that, let's take
this opportunity to rename in-memory remotes to anonymous as that's
really what sets them apart.
`git_submodule` objects were already refcounted internally in case
the submodule name was different from the path at which it was
stored. This makes that refcounting externally used as well, so
`git_submodule_lookup` and `git_submodule_add_setup` return an
object that requires a `git_submodule_free` when done.
- Add minimal, patience diff options to diff example. libgit2
`diff_xdiff.git_xdiff_init` already supports these flags, so
no additional change is necessary.
- Remove minimal and patience flag addition from project list.
- added MSVC cmake definitions to disable warnings
- general.c is rewritten so it is ansi-c compatible and compiles ok on microsoft windows
- some MSVC reported warning fixes
The callback-based method of listing remote references dates back to the
beginning of the network code's lifetime, when we didn't know any
better.
We need to keep the list around for update_tips() after disconnect() so
let's make use of this to simply give the user a pointer to the array so
they can write straightforward code instead of having to go through a
callback.
Update the explanation to reflect our use of git_status_list_new() and
make the breaks in rocco more meaningful.
Clarify why GIT_STATUS_CURRENT and index_to_workdir don't always imply
each other. Fixes#1740.
This changes `git_index_read` to have two modes - a hard index
reload that always resets the index to match the on-disk data
(which was the old behavior) and a soft index reload that uses
the timestamp / file size information and only replaces the index
data if the file on disk has been modified.
This then updates the git_status code to do a soft reload unless
the new GIT_STATUS_OPT_NO_REFRESH flag is passed in.
This also changes the behavior of the git_diff functions that use
the index so that when an index is not explicitly passed in (i.e.
when the functions call git_repository_index for you), they will
also do a soft reload for you.
This intentionally breaks the file signature of git_index_read
because there has been some confusion about the behavior previously
and it seems like all existing uses of the API should probably be
examined to select the desired behavior.
It was there to keep it apart from the one which read in from a file on
disk. This other indexer does not exist anymore, so there is no need for
anything other than git_indexer to refer to it.
While here, rename _add() function to _append() and _finalize() to
_commit(). The former change is cosmetic, while the latter avoids
talking about "finalizing", which OO languages use to mean something
completely different.
This reorganizes a few of the examples so that the main function
comes first with the argument parsing extracted into a helper
that can come at the end of the file (so the example focuses more
on the use of libgit2 instead of command line support). This also
creates a shared examples/common.[ch] so that useful helper funcs
can be shared across examples instead of repeated.
The user is unable to derive the number of deltas in the pack, as that
would require them to capture the stats exactly in the moment between
download and final processing, which is abstracted away in the fetch.
Capture these numbers for the user and expose them in the progress
struct. The clone and fetch examples now also present this information
to the user.
Instead of having functions with so very many parameters to pass
hunk and line data, this takes the existing git_diff_hunk struct
and extends it with more hunk data, plus adds a git_diff_line.
Those structs are used to pass back hunk and line data instead of
the old APIs that took tons of parameters.
Some work that was previously only being done for git_diff_patch
creation (scanning the diff content for exact line counts) is now
done for all callbacks, but the performance difference should not
be noticable.
This lays groundwork for separating formatting options from diff
creation options. This groups the formatting flags separately
from the diff list creation flags and reorders the options. This
also tweaks some APIs to further separate code that uses patches
from code that just looks at git_diffs.
This makes no functional change to diff but renames a couple of
the objects and splits the new git_patch (formerly git_diff_patch)
into a new header file.
When given an ODB from which to read objects, the indexer will attempt
to inject the missing bases at the end of the pack and update the
header and trailer to reflect the new contents.
The text progress and update_tips callbacks are already part of the
struct, which was meant to unify the callback setup, but the download
one was left out.
Fixed the filter order to match core Git, too.
This test demonstrates an interesting behavior of core Git (which
is totally reasonable and which libgit2 matches, although mostly
by coincidence). If you use the ident filter and commit a file
with a garbage ident in it, like '$Id: this is just garbage$' and
then immediately do a 'git checkout-index' with the new file, Git
will not consider the file out of date and will not overwrite the
file with an updated $Id$. Libgit2 has the same behavior. If you
remove the file and then do a checkout-index, it will be replaced
with a filtered version that has injected the OID correctly.
Unfortunately git-core uses the term "unborn branch" and "orphan
branch" interchangeably. However, "orphan" is only really there for
the checkout command, which has the `--orphan` option so it doesn't
actually create the branch.
Branches never have parents, so the distinction of a branch with no
parents is odd to begin with. Crucially, the error messages deal with
unborn branches, so let's use that.
