* bug#41465: 28.0.50 (but also earlier versions); etags asserion error (with too many files?) @ 2020-05-22 19:31 Gregor Zattler 2020-05-22 21:38 ` Dmitry Gutov 0 siblings, 1 reply; 7+ messages in thread From: Gregor Zattler @ 2020-05-22 19:31 UTC (permalink / raw) To: 41465 Dear emacs developers, I get an assertion error when executing the following line (from a cron job of mine): grfz@no:~/src$ find ~/src -type f -print0 | egrep -zZ '(\.el|\.c|\.h)(\.gz)?$' | xargs -0r etags etags: etags.c:1987: pfnote: Assertion `name == NULL || name[0] != '\0'' failed. xargs: etags: terminated by signal 6 125 (master *) grfz@no:~/src$ This happens with etags from debian buster, as with etags build from emacs-27 branch of emacs git repo, as with etags build from feature/native-comp branch. Under ~/src there is also the linux kernel git repo. There is no assertion error if I filter it out: $ find . -type f -print0 | egrep -vzZ linux | egrep -zZ '(\.el|\.c|\.h)(\.gz)?$' | xargs -0r etags 0 (master *) grfz@no:~/src$ There is also no assertion error if I filter for .el files only: 125 (master *) grfz@no:~/src$ find ~/src -type f -print0 | egrep -zZ '(\.el)(\.gz)?$' | xargs -0r etags 0 (master *) grfz@no:~/src$ Therefore I assume this somehow is related to the number of files.

So if you can determine which file fails to parse, and send us an example, that should help fix it. ^ permalink raw reply [flat|nested] 7+ messages in thread

Thanks you for that addition. Indeed, when I configure Emacs with CFLAGS='-g -O2' --enable-checking etags does abort with assertion errors you described. ^ permalink raw reply [flat|nested] 7+ messages in thread

Makes sense. > But shouldn't there also be no assertion errors with > --enable-checking ? There shouldn't be. So it's a valuable bug report, just less urgent than we might have decided previously. I'll let our developers who know etags better handle it from here. ^ permalink raw reply [flat|nested] 7+ messages in thread

Thanks, I applied the trivial band-aid to fix this on the emacs-27 branch. ^ permalink raw reply [flat|nested] 7+ messages in thread
