Bug 261675 – Interaction between digest and parallel-fetch options can cause problems.

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Hans de Graaff 2009-03-08 12:40:17 UTC]

When the 'digest' and 'parallel-fetch' FEATURES are both turned on in /etc/make.conf, then bad things can happen when trying to install a number of packages that share the same source file. Examples of such packages are mozilla-firefox and xulrunner, or the recent gtk-related *-sharp packages.

What seems to happen is that the digest is recalculated based on a partial download, leading to digest verification errors later on since the digest was calculated against a partial download that no longer exists nor can be downloaded anywhere anymore.

yesterday i had problem with qt-4.5.0, which is divided into several ebuilds.
i've installed (in order): qt-core, qt-dbus, qt-sql, qt-scripts, qt-test (and few more). after instalation of qt-core, emerge fails with qt-dbus, couse it expected file to have size of 49MB (and qt-sources has 108MB), so i've made sync. after sync i was able to install qt-dbus, but i had the same problem with qt-sql (which wanted sources of lenghr 22MB AFAIR). another sync and the same problem with qt-scripts. after third sync the problem disapear and i was able to install rest of qt

im not sure if it's related with this bug, but it looks similar

The previous patch missed a case. This patch should cover all cases.

There was one other thing that I had overlooked. Now it should work perfectly.

This is fixed in 2.2_rc24 which is in package.mask. I'll close this bug when it's also released in 2.1.6.8.

This is released in 2.1.6.8.
