test-shelve: do not use non-portable pipe-and

parsers: suppress warning of signed and unsigned comparison at nt_init Spotted by CC=clang CFLAGS='-Wall -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -Wshorten-64-to-32': mercurial/parsers.c:1580:24: warning: comparison of integers of different signs: 'Py_ssize_t' (aka 'long') and 'unsigned long' [-Wsign-compare] if (self->raw_length > INT_MAX / sizeof(nodetree)) {

parsers: correct type of temporary variables for dirstate tuple fields These fields are defined as int. This eliminates the following warning spotted by CC=clang CFLAGS='-Wall -Wextra -Wno-missing-field-initializers -Wno-unused-parameter -Wshorten-64-to-32': mercurial/parsers.c:625:29: warning: comparison of integers of different signs: 'uint32_t' (aka 'unsigned int') and 'int' [-Wsign-compare] if (state == 'n' && mtime == now) {

test: enforce v1 type in 'test-bundle2-remote-changegroup.t' This bundle command is meant to generate a bundle1, we enforce that to avoid test's misbehavior when moving to general-delta by default.

editmerge: properly quote variables Previously, files with spaces would break editmerge.

commands.resolve: print out warning when only driver-resolved files remain 'hg resolve --all' will be the canonical way to run the 'conclude' step of the merge driver.

merge.mergestate: set merge driver state to 's' if there's none present This allows mergestate.mdstate() to return 's' if there's nothing to be done on the merge driver end.

merge.mergestate: only check for merge driver when property is accessed Otherwise 'hg update --clean', 'hg rebase --abort' etc wouldn't work.

localrepo.commit: abort if merge driver's conclude step hasn't been run yet This case also requires 'hg resolve --all' to be run before continuing.
