libgit2 / libgit2-backends Goto Github PK

It would be good to add a LICENSE.md to this repo to clarify what the distribution terms are. I would assume that it is under the same license as https://github.com/libgit2/libgit2, but again clarification from the project is appreciated.

Hello, libgit2 team

First, great project!

I have a question regarding the mysql backend:
This is the code to create a blob from buffer, it's a string.

const char str[] = "Hello, World!";
git_blob_create_frombuffer(&oid, mysql_odb_backend->repo, str, strlen(str));

The blob successfully inserted to the odb table, the uncompress(data) is the string content

But I don't understand the oid column value, as according to git concept, it's sha1 value of the data content, please correct me if I'm wrong.

So I did a validation

select  lower(hex(oid)),
        type, 
        size, 
        convert(uncompress(data),char(100)),
        sha1(uncompress(data))
from git2_odb

result:

I found that the hex oid value is not the same as sha1 data, is this correct? or I'm doing it in the wrong way?

Thank you!

Best Regards,
Jerry

Hi!

The mysql backend seems quite out of date.
Are you considering updating it? If not, do you know of any other projects doing the same thing?

Thanks in advance

Does this mean git is backed by redis if i use the redis backend?

Is there one developed for ssdb from ideawu?

index should be 1

I'm on OSX Yosemite and I can't build the memcached backend.

Here are the steps I'm executing:

brew install libmemcached
brew install libgit2
git clone https://github.com/libgit2/libgit2-backends.git
cd libgit2-backends
cmake memcached
cmake --build .

Here is partial output from the build step:

$ cmake --build .

It appears that the compiler can't find libgit2, but cmake seemed to find it just fine in the cmake memcached step.

I wonder if it is possible to have multiple repositories per for example a single mysql database?
And is there also a refdb backend for mysql?

Should hiredis.c return a git_error_code type and not git_error_t? Libgit2 checks for if (error < 0) which does not catch git_error_t types.

This manifested in a nullptr instead of an error when trying git_blob_lookup_prefix against hiredis backend.

See https://github.com/libgit2/libgit2-backends/blob/master/redis/hiredis.c#L158 and https://github.com/libgit2/libgit2/blob/master/src/object.c#L190.

Is it possible to use ssdb instead of redis?
