GVFS 1.0.18115.1

Major updates:

• Switched over to use the Windows Projected File System (ProjFS) optional feature on RS4 and later. ProjFS is the new name for the GvFlt driver and its associated user mode library.
• The local file size cache was migrated from ESENT to SQLite
• Git commands are now allowed to delete an empty directory
• Many other reliability improvements in interactions between GVFS and the file system, and between GVFS and git

Perf improvements:

• Better memory management in git, creating a savings of up to half a second on commands that parse the index
• Added a new mutli-pack index file to git, allowing it to become much more efficient at finding an object when there are a large number of local packfiles
• Added a git config setting to disable the calculations for detecting force pushes during 'git fetch' and 'git pull'. That calculation can take 10's of seconds on a large graph, and users can now opt out of it.
• Due to the transition to SQLite, the file sizes cache can now live in the volume-wide .gvfsCache folder and be shared by multiple repos, causing fewer round trips to the server while enumerating files
• The post-command step to update placeholder files now batches its size requests to the server, resulting in significant speedups in situations where many placeholder files needed to be updated
• The client will now also query the /gvfs/sizes endpoint on a cache server that implements that endpoint, reducing the latency on those requests even further
• Sped up GVFS's parsing of the git index, shaving off 2-3 seconds for a large index file

GVFS 1.0.18026.1

New features:

• Added a new volume-wide cache for downloaded git objects that is shared amongst multiple repos. Only newly created repos will use the new cache location. Existing clones will continue to use their own private cache.
• The installer now unmounts and remounts existing repos automatically
• GVFS no longer forces an antivirus exclusion. This was a relic from long ago when the gvflt driver and the Defender driver used to interfere with each other, but antivirus is no longer GVFS's concern.
• Added better diagnostic info in the GVFS logs when there are network errors
• git status now supports an option to avoid doing its ahead/behind calculations. This allows the user to decide if they want to skip that overhead if all they care about is the status of the working directory.

Bug fixes:

• Lots of bug fixes to make GVFS's file writes (e.g. to its database files) more reliable, even in the face of power loss
• GVFS can now recover from corrupted git object files (e.g. caused by a torn write), by re-downloading them whenever git asks for an object. The assumption is that git would not be asking GVFS for it if the object was valid.
• Fixed an annoying bug where a Ctrl+C'd git process could leak a GVFS lock
