Plakar on poolp.org

Out of my cave, lots of updates

Tue, 11 Jun 2024 21:00:00 +0100

TL;DR:
I have been silent for a while due to personal matters but I did a ton of stuff on OpenSMTPD, plakar and a handful of other projects.

Why the silence ?
#

My last post was a bit unusual, far off from the usual light tone, and followed by months of silence despite my habit of writing almost monthly.

Plakar: an avalanche of changes

Thu, 02 Nov 2023 10:13:00 +0200

TL;DR:
Significant refactoring to improve its performance, implemented read and write semaphores to throttle chunkers and reduce memory usage, introduced a repository index and packfiles to decrease the number of I/O operations, also intrioduced a new HTTP storage backend.

A ton of refactors
#

I’ve done so much work on plakar in the past few weeks that I don’t even know what to begin with…

TL;DR:
TL;DR: a lot of work in plakar, but also on CDC and index optimization.

Optimized `go-fastcdc`
#

I ran into a benchmark which included my implementation of the FastCDC algorithm, and it made me realise that it was not on par with alternative implementations:

Plakar: vfs importer interface

Sun, 06 Aug 2023 00:44:00 +0200

TL;DR:
I reworked the virtual filesystem layer in plakar, making it possible to write custom importers of data: use plakar to backup an s3 bucket, for instance.

Plakar: snapshot forking and tagging

Sun, 23 Jul 2023 10:24:00 +0200

TL;DR:
plakar gained two minor features, snapshots fork-ing and snapshots tagging, which makes it possible to unlock several major new features in a relatively short future.

Plakar is not only for backups
#

If you have followed my work on this project, you may have assumed that plakar was intended solely for backups: it’s not entirely the case.

Sun, 22 May 2022 13:27:00 +0200

TL;DR:
tons of plakar work, most notably on indexes, performances, clone & sync and fuse.

Code-unrelated work

I’ll start with code unrelated work !

April 2022: plakar keys and UI stuff

Fri, 01 Apr 2022 01:52:00 +0200

TL;DR:
I did key and UI stuff, mostly search related. There’s going to be plenty of images in this post.

Reworked plakar keys
#

I won’t expand much on that as I’m not done yet, but I spent a couple days reworking the way plakar handles keys for encrypted repositories.

March 2022: plakar clone and plakar sync

Sun, 06 Mar 2022 00:51:00 +0200

TL;DR:
implemented cloning and synchronization between plakar repositories

Slacked a bit
#

Shortly after I published my yearly retrospective, I was hit with two highly annoying personal issues that kept me very busy these last two months. I finally got everything back under control, my mind is mostly free again and I resumed playing with plakar.

December 2021: a bit of plakar, a bit of go-fastcdc and some useless stuff

This activity report will be short
#

This activity report will be short because I spent the last ten days caring for my kid who got sick… before catching his stomach bug myself and spending the last few days in a somewhat familiar and unpleasant hell, unable to do everything I intended for this month.

November 2021: a bit of go-ipcmsg, a bit of go-privsep and a ton of plakar

Tue, 26 Oct 2021 07:40:00 +0200

TL;DR:
I still have a discord, feel free to join. I worked on go-ipcmsg to make it nicer, go-privsep to make it more useable, and A LOT on plakar to make it plakar.

Go-ipcmsg
#

In April, I wrote about go-ipcmsg, a package to bring an imsg(3)-like API to Golang and help me write code involving message and fd-passing between processes.

Tue, 26 Oct 2021 07:40:00 +0200

TL;DR:
I have a discord now, feel free to join. I refactored plakar, implemented a local cache, improved parallelism, modified the push strategy, played with fuse and networking. I also did other stuff but let’s keep that out of this article.
