v0.18.0

API Changes

• All callbacks that go to libgit2 now have an optional waitForResult flag that can be true/false. Defaults to false. When true it will not stop libgit2 from continuing on before the JS code is fully executed and resolved (in cases of a Promise). This is useful for progress callbacks (like fetching) where the bubbling up of the progress to JS doesn't really need the C/C++ code to wait for the JS code to fully handle the event before continuing. This can have serious performance implications for many callbacks that can be fired quite frequently.
• given_opts in Revert.revert are now optional
• checkout_opts in Reset.fromAnnotated and Reset.reset are now optional
• Reset.fromAnnotated is now async
• message on Stash.save is now optional
• Added processMergeMessageCallback on Repository#mergeBranches to allow for custom merge messages
• Add beforeFinishFn to Repository#rebaseBranches and Repository#continueRebase. This is called before the invocation of finish(). If the callback returns a promise, finish() will be called when the promise resolves. The beforeFinishFn will be called with an object that has on it:
  • ontoName The name of the branch that we rebased onto
  • ontoSha The sha that we rebased onto
  • originalHeadName The name of the branch that we rebased
  • originalHeadSha The sha of the branch that was rebased
  • rewitten which is an array of sha pairs that contain which contain what the commit sha was before the rebase and what the commit sha is after the rebase

v0.17.0

Targeted Platform Changes

In this release we had added support for Node v7 and latest Electron. We have removed support for Node v0.12 and v5.

We are also deprecating nw.js support since it is currently broken, no one in the current team uses it and we would not be able to currently support nw.js in an effective manner with a good user experience.

Now building against shared libcurl lib

For proxy support we now use libcurl for HTTP/HTTPS transport which should have no noticeable change in NodeGit remote operations but if changes are noticed this is worth mentioning as a potential source.

Memory leak fixes and stability increases

Many PR's were made to fix memory leaks as they were found so memory usage should go down in this version for long running scripts. Additionally, when performing operations with callbacks (transfer progress, credentials, etc...) there was a small chance for a segfault when NodeGit would schedule the callback to go into JavaScript. This is now fixed.

Fixes to the build

Many users, especially on windows, were experiencing errors during the build. The build still isn't perfect but a lot of the bugs were fixed.

Bump libgit2 to 0bf0526

The majority of changes to NodeGit v17 were in libgit2. The API breaking changes that are known are:

• RevWalk is returning different results libgit2 PR #3921

v0.15.0

• Update to libgit2 @ 37dba1a PR #1041

This updates NodeGit to use the latest HEAD version of libgit2. The plan for staying on the official tagged releases of libgit2 is that they will get a maintenance branch and not-breaking API fixes will be backported to them. The first branch of this sort is maint/0.14. Going forward new releases of NodeGit will follow closely to the master branch of libgit2.

Summary of changes that were brought in:

libgit2/libgit2@37dba1a

Changes or improvements

• NodeGit.FetchOptions, and NodeGit.PushOptions now have a proxyOpts field that accepts a NodeGit.ProxyOptions object that allows NodeGit to use a proxy for all remote communication
• NodeGit.MergeOptions has a defaultDriver field that lets the caller change the driver used to when both sides of a merge have changed

API additions

• Commit.createWithSignature allows the caller to create a signed commit. There are no tests for this currently so it's labelled experimental.
• Blob, Commit, Tag, and Tree all have a new prototype dup method on them to make a low-level copy of the libgit2 object if needed.
• Odb#expandIds is exposed which takes in a list of short ids and expands them in-place to the full id of the object in the database

v0.14.0

• Improve lifecycle scripts and install process PR #1055
• Fix example code PR #1058

v0.13.2

• Stop RevWalk#walk from swallowing errors in the callback PR #1047
• Stop swallowing errors in the install script PR #1048
• Fix initializing submodules when installing from npm PR #1050
