filter-process: New command that can make git add/checkout faster when there are a lot of unlocked annexed files or non-annexed files, but that also makes git add of large annexed files slower. Use it by running: git config filter.annex.process 'git-annex filter-process' Fully tested and working, but I have not benchmarked it at all. And, incremental hashing is not done when git add uses it, so extra work is done in that case. Sponsored-by: Mark Reidenbach on Patreon

# NAME
|
|
|
|
git-annex filter-process - long running git filter process for git-annex
|
|
|
|
# SYNOPSIS
|
|
|
|
git annex filter-process
|
|
|
|
# DESCRIPTION
|
|
|
|
By default, `git-annex smudge` is used as the git filter driver.
|
|
This is an alternative way to accomplish the same thing, using git's
|
|
long-running filter process interface.
|
|
|
|
To enable using this, run:
|
|
|
|
git config filter.annex.process 'git-annex filter-process'
|
|
|
|
There will be no visible difference in behavior between enabling this and
|
|
not, besides changes in speed and memory use when using git.
|
|
|
|
When this is not enabled, each file that git wants to filter involves
|
|
starting up a new `git-annex smudge` process. Starting many such processes
|
|
for many files can be slow, and can make commands like `git checkout` and
|
|
`git add` slow when they are operating on a lot of files. (A lot of locked
|
|
annexed files do not make `git checkout` slow, but unlocked files and
|
|
non-annexed files do slow it down.)
|
|
|
|
On the other hand when this is enabled, `git add` of a large file does an
|
|
unncessary extra read of the file, and pipes its contents into git-annex.
|
|
So if you enable this, it will be faster to use `git-annex add` to add
|
|
large files to the annex, rather than `git add`. Other commands that
|
|
add files, like `git commit -a`, are also impacted by this.
