It's a bit odd that you see an 8G diff and YP AB saw 5 GB but that's=20 close enough for now. Please run the same analysis for 1.84 update both before and after=20 removing the src/gcc .

I didn't check for the other 4 GB yet...


rust, rust-native, nativesdk-rust, cargo and so on.

Should we do that an host the tarball  on yoctoproject.org?

Should we write a custom unpack rule to --exclude=3Drustc-1.83.0-src/src/gcc ?

Or just delete the directory in a do_unpack postfunc?

Yash has 1.84 mostly working and 

will add a post unpack change to rm -rf rustc-1.83.0-src/src/gcc


Or wait for 1.85?

This likely won't get merged until YP-5.3. We'll see how long it takes to be ready for review.



This is annoying "bloat" which we at least need = to identify and work out a plan for.



Next week, I'll also dig into the 'tmp' usage increase to understand where the 5 GB that Richard reported comes from.

See above, I'm guessing so it needs to be confirmed but...


Yashe,

Can you review the reason for the FSspace usage difference between 1.82, 1.83 when you have time?


The following differences were seen when compared the FS usage between v1.82 and v1.83:

I did a basic "bitbake rust" build (in separate dir pat= hs) to check the effect on Yocto build FS:

The TMPDIR FS usage:

TMDIR FS usage          &= nbsp;              &nbs= p;               &= nbsp;                   &n= bsp;               = ;               &n= bsp;               = ;               &n= bsp;               = ; v1.82.0             &= nbsp;                          &n= bsp;               = ;  v1.83.0
du -sh poky/build/tmp/         = ;               &n= bsp;               = ;               &n= bsp;               = ;                &= nbsp;              = ;                  &n= bsp;        65 G       =               &nbs= p;               &= nbsp;              &n= bsp;          73 G
du -sh  poky/build/tmp/work/core2-64-poky-linux/rust/1.8x.0/rustc-1.8x.0-= src/                &n= bsp;            9.8 G  =               &nb= sp;                          &n= bsp;               = ;  12 G


It's more 8G in v1.83.


Thanks Yash!

It's a bit odd that you see an 8G diff and YP AB saw 5 GB but that's close enough for now.

Please run the same analysis for 1.84 update both before and after removing the src/gcc .

Please summarize the data for 1.82, 1.83 and the two sets of data for 1.84.

I'd expect 1.84 + "rm -rf src/gcc" to be somewhat larger = than 1.82 but much smaller than 1.83.


../Randy



The main reason for FS usuage differences in v1.83 are:
1. Addition of gcc  ~1.1 G.2. The addition of enzyme AD sub module ~392 M=
b.
