From 2d9bb56e554b17488c0f8984f34c026a66cdce67 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 24 Oct 2013 19:10:38 +0200 Subject: Fix segfault on Darwin Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly segfaulted on Darwin: http://hydra.nixos.org/build/6175515 http://hydra.nixos.org/build/6611038 It turns out that this is because the binary cache substituter somehow ends up loading two versions of SQLite: the one in Nixpkgs and the other from /usr/lib/libsqlite3.dylib. It's not exactly clear why the latter is loaded, but it appears to be because WWW::Curl indirectly loads /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation, which in turn seems to load /usr/lib/libsqlite3.dylib. This leads to a segfault when Perl exits: #0 0x00000001010375f4 in sqlite3_finalize () #1 0x000000010125806e in sqlite_st_destroy () #2 0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY () #3 0x00000001001c8155 in XS_DBI_dispatch () ... #14 0x0000000100023224 in perl_destruct () #15 0x0000000100000d6a in main () ... The workaround is to explicitly load DBD::SQLite before WWW::Curl. --- scripts/download-from-binary-cache.pl.in | 1 + 1 file changed, 1 insertion(+) (limited to 'scripts/download-from-binary-cache.pl.in') diff --git a/scripts/download-from-binary-cache.pl.in b/scripts/download-from-binary-cache.pl.in index ab72e83e8f35..950bcd178527 100644 --- a/scripts/download-from-binary-cache.pl.in +++ b/scripts/download-from-binary-cache.pl.in @@ -1,6 +1,7 @@ #! @perl@ -w @perlFlags@ use DBI; +use DBD::SQLite; use File::Basename; use IO::Select; use Nix::Config; -- cgit 1.4.1
