[M] Change in osmo-dev[master]: gen_makefile: add --autoreconf-in-src-copy arg

Attention is currently required from: fixeria, lynxis lazus, pespin. Hello fixeria, lynxis lazus, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-dev/+/39404?usp=email to look at the new patch set (#2). Change subject: gen_makefile: add --autoreconf-in-src-copy arg ...................................................................... gen_makefile: add --autoreconf-in-src-copy arg When this new argument is set, do not run "autoreconf -fi" directly in the source directory. Instead, make a copy of all relevant sources in the git repository (everything except .git and files that are matched by gitignore) right before working with the source dir. Then use that copy instead. This avoids the problem that ./configure refuses to run if it has already been executed in the source dir. (It aborts and asks the user to run "make distclean" first, which is especially annoying if it has to be done in multiple source dirs before being able to build successfully.) Copying the sources is very fast due to generating a list of files that need to be copied first, and due to using rsync which skips the copy if the file size and timestamp already match. On my machine the copying is not noticable except for the additional prints: updating src_copy: /home/user/.cache/osmo-ttcn3-testenv/host/make2/src_copy/osmo-mgw/ updating version: 1.13.1.38-78ee9 Change-Id: I18ac50e3441df81e1fe7d8d5321df7e80ab9c650 --- M .gitignore M gen_makefile.py A src/_update_src_copy.sh 3 files changed, 164 insertions(+), 14 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-dev refs/changes/04/39404/2 -- To view, visit https://gerrit.osmocom.org/c/osmo-dev/+/39404?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: newpatchset Gerrit-Project: osmo-dev Gerrit-Branch: master Gerrit-Change-Id: I18ac50e3441df81e1fe7d8d5321df7e80ab9c650 Gerrit-Change-Number: 39404 Gerrit-PatchSet: 2 Gerrit-Owner: osmith <osmith(a)sysmocom.de> Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: lynxis lazus <lynxis(a)fe80.eu> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: lynxis lazus <lynxis(a)fe80.eu>
