Today I decided to release sam 0.2.0. There are only a handful of new features in there but it’s still releaseworthy! See the previous sam announcement for more information on the tool itself.

Source path and lib folders

Let’s take a look at what sam tells us when launching it.

sam version 0.2.0

Usage: sam [update|get|status|promote]

Commands
  * update: update sam's grimoir of formulas
  * get [USEFILE]: clone and/or pull all dependencies
  * status [USEFILE]: display short git status of all dependencies
  * promote [USEFILE]: replace read-only github url with a read-write one for given use file
  * clone [--no-deps] [REPONAME]: clone a repository by its formula name

Note: All USEFILE arguments are optional. By default, the
first .use file of the current directory is used

Changes to “clone”

One thing that’s new is that sam clone will now also clone dependencies by default. So if you do sam clone dye by example, you’ll get a copy of my graphics framework and all its dependencies.

In my case, because I already have dye, it’ll only update:

$ sam clone dye
[dye:master]
Repository /Users/amos/Dev/dye exists already. Pulling...
 > Current branch master is up to date.
[sdl2:master] (<= dye)
 > Current branch master is up to date.
[stb-image:master] (<= dye)
 > Current branch master is up to date.
[freetype2:master] (<= dye)
 > Current branch master is up to date.
[deadlogger:master] (<= dye)
 > Current branch master is up to date.

If you want to only clone or update one the formula you specify and none of its dependencies, you can use the --no-deps option.

Changes to “update”

Previously, sam update only updated its library of formulas (also called grimoir). Now it also recompiles it. It’s still pretty fast though:

$ sam update
Pulling repository /Users/amos/Dev/sam
 > Current branch master is up to date.
Recompiling sam
 > Cleaning up outpath and .libs
 > Build order: [sam, sdk]
 > [ OK ]

This takes around 6s on my system - and most of that is spent waiting for SSL negotiation with GitHub!

So there you have it, from now on you’ll be able to sam update to keep both your grimoir up-to-date and sam itself.

Profiling linkers

Jan 03, 2022

6 min #rust · #release-engineering

In the wake of Why is my Rust build so slow?, developers from the mold and lld linkers reached out, wondering why using their linker didn’t make a big difference.

Of course the answer was “there’s just not that much linking to do”, and so any difference between mold and lld was within a second. GNU ld was lagging way behind, at four seconds or so.
