 Posted: Thu Feb 29, 2024 12:33 pm Post subject: Some local + binhost builds bloated with full PORTAGE_TMPDIR |
 |
|
As an example in terminal: | Code: | | ALSA lib /var/no-tmpfs/portage/media-libs/alsa-lib-1.2.10-r2/work/alsa-lib-1.2.10/src/pcm/pcm.c:8684:(snd_pcm_recover) underrun occurred |
$PORTAGE_TMPDIR seems stored in binary.
If so, what am I doing wrong?
Is there a way to lower this fingerprint?

| Some build systems invoke the compiler with the absolute path of the source file. This causes __FILE__ to be that absolute path. If you want to stop this, patch the build system to use a relative path to the source file. |

Hum, | Code: | | [EDIT]equery f alsa-lib | while read line;do if [ -f $line ]; then grep -a portage $line;fi;done |
doesn't return anything.
If that command line is correct, it sounds like $PORTAGE_TMPDIR path value isn't stored as clear text...
In any case this is a very uncomfortable situation imo.

Why is this uncomfortable?
That command seems incorrect, as it does not allow grep to print from binary files. |

I don't like bloat, as well as chasing it away: 37 references * 77 characters.

Thks 4 ur attention not providing the 2 char long "-a" missing bit, interest & support.

37 instances of 77 characters comes out to 2849 bytes extra. Depending on filesystem block size, there is a good chance that you would get zero savings from removing the extra bytes.
As for not providing -a, you only remarked on whether the command was correct. I noted it was not. You found or remembered the correct option with a bit of prompting, so I think my comment was sufficient. |

Compaq laptop here:
PATA i.e. 512 bytes block,
1024 Mb RAM here. Thus no-tmpfs in $PORTAGE_TMPDIR.
Plz don't bloat my RAM.

| Hard disk block size is irrelevant if your filesystem uses a larger block size. Did you configure ext4 (or equivalent) to use a small enough block size? One of my filesystems here picked a 4096 byte logical block size, so any non-empty file on that filesystem must occupy at least 4096 bytes. |

I've checked that PATA, where ext4 is indeed configured to use 4Kb block instead of 512b as I wrongly thought.
That mistake brings a new maintenance task to be planned.
A few packages here are flooded with PORTAGE_TMPDIR references.
280 libgromacs.so
246 libportaudio.so
194 libz3.so
98 libgnutls.so
85 liblldb.so
enough for an at least one superfluous 4K file system block allocation.

How many superfluous filesystem block allocations are required to store this thread? 
Remember that filesystem blocks cannot be shared across files, so each package needs to have each of its files accounted individually. |

This is how (some) compilers work. Why are you like this? |

Long time, no see.
Glad to see you back.
I've checked with alsa-libs binary from one other distro.
It doesn't contain such a build path.

Non Gentoo distro binaries don't contain the Gentoo build path? Word?
They'll contain whatever path their own build system used. |

| That looks wrong. Shouldn't Arch have printed 0 if there were no matches? Why are you redirecting stderr to /dev/null? |
