log: add an assertion about fctx not being None in patch.diff() As noted in the comment, this should not happen as removed files (the cause of fctx2 being None) are caught earlier.

log: handle removed files with --line-range patterns I.e. abort when the pattern corresponds to a removed file, as done with bare file patterns.

log: disable bare file patterns with --line-range Currently, specifying both a line-range pattern and a bare file pattern results in an AND operation whereas we probably want an OR so that bare file patterns are like a line-range pattern with all lines specified. So, until this works as expected, we disable this.

log: switch to FROMLINE:TOLINE syntax for -L/--line-range This is more consistent with the followlines() revset.

log: handle binary files in --line-range patterns When a file is binary patch.trydiff() would yield None for 'hunkrange'. Handle this case in the hunksfilter() callback. Add tests with and without diff.git option as binary handling differs depending on this option's value.

build: build deb/rpm independently on config/extensions in the host system Reverts 5aac617a028d and replaces it with a more general solution. - works for both rpm and deb - sidesteps eventual problems with local extensions that have nothing to do with the build process (hg-git, for example, fails with version 4.4 because dedab036215d removed peerrepository, and hg-git still uses it as of 0.8.9)

config: also gather effect-flags on experimental.evolution Effect-flags config was in flight while the previous evolve config renaming was written. Now that both landed, gather effect-flags in experimental.evolution like the others evolve-related configurations. Differential Revision: https://phab.mercurial-scm.org/D1197

obsfate: rename obsfate into obsolete in default mapfile Like the previous patch, replace obsfate by obsolete in default mapfile. Differential Revision: https://phab.mercurial-scm.org/D1190
