File sv-bug-48030-find-exec-plus-does-not-pass-all-arguments.patch of Package findutils.2821
Upstream patch, to be removed with findutils-4.7.0 http://git.sv.gnu.org/cgit/findutils.git/commit/?id=8cdc9767e3 Differences to upstream patch: - Fix conflict in NEWS. - Strip down to the core change, i.e., remove test. Manual test (or trigger the bug with the unpatched version): #-test case start- #!/bin/bash #cd $HOME mkdir RashuBug RashuBug-bin seq -f "RashuBug/abcdefghijklmnopqrstuv%04g" 901 | xargs touch seq -f "RashuBug/abcdefghijklmnopqrstu%04g" 902 3719 | xargs touch # Number of files we have created in directory: ls RashuBug/* | wc -l #output: 3719 ## Now create an echo command which is 6 characters long ln -s `which echo` RashuBug-bin/echo56 PATH="$PWD/RashuBug-bin:$PATH" ## See the difference in the output of the following commands. # Correct: -exec \; find RashuBug -type f -exec echo56 '{}' \; | tr ' ' '\n' | wc -l #output: 3719 # Correct: -exec echo + find RashuBug -type f -exec echo '{}' + | tr ' ' '\n' | wc -l #output: 3719 # The last file is missing with the buggy find(1). find RashuBug -type f -exec echo56 '{}' + | tr ' ' '\n' | wc -l #buggy output: 3718 #expected: 3719 #rm -rf RashuBug RashuBug-bin #-test case end- ---------------------------------------------------------------------- From d15e640fc76f8b931549f79f2edc86d5e552e8bf Mon Sep 17 00:00:00 2001 From: Bernhard Voelker <mail@bernhard-voelker.de> Date: Tue, 31 May 2016 00:31:50 +0200 Subject: [PATCH] Fix bug #48030: find: -exec + does not pass all arguments in certain cases When the -exec arguments buffer (usually 128k) is full and the given command has been executed with all that arguments, find(1) missed to execute the command yet another time if only 1 another file would have to be processed. Both find(1), i.e., nowadays FTS-version, and oldfind are affected. This bug was present since the implementation of '-exec +' in 2005, see commit FINDUTILS_4_2_11-1-25-gf0a6ac6. * lib/buildcmd.c (bc_push_arg): Move the assignment to set 'state->todo' to 1 down after the immediate execution which resets that flag. * NEWS (Bug Fixes): Mention the fix.
