rebase: allow collapsing branches in place (issue3111) We allow rebase plus collapse, but not collapse only? I imagine people would rebase first then collapse once they are sure the rebase is correct and it is the right time to finish it. I was reluctant to submit this patch for reasons detailed below, but it improves rebase --collapse usefulness so much it is worth the ugliness. The fix is ugly because we should be fixing the collapse code path rather than the merge. Collapsing by merging changesets repeatedly is inefficient compared to what commit --amend does: commitctx(), update, strip. The problem with the latter is, to generate the synthetic changeset, copy records are gathered with copies.pathcopies(). copies.pathcopies() is still implemented with merging in mind and discards information like file replaced by the copy of another, criss-cross copies and so forth. I believe this information should not be lost, even if we decide not to interpret it fully later, at merge time. The second issue with improving rebase --collapse is the option should not be there to begin with. Rebasing and collapsing are orthogonal and a dedicated command would probably enable a better, simpler ui. We should avoid advertizing rebase --collapse, but with this fix it becomes the best shipped solution to collapse changesets. And for the record, available techniques are: - revert + commit + strip: lose copies - mq/qfold: repeated patching() (mostly correct, fragile) - rebase: repeated merges (mostly correct, fragile) - collapse: revert + tag rewriting wizardry, lose copies - histedit: repeated patching() (mostly correct, fragile) - amend: copies.pathcopies() + commitctx() + update + strip

largefiles: add --all-largefiles flag to pull

largefiles: refactor downloading of all largefiles to generic function

unbundle: move bookmark update outside the lock d16c99f16f00 introduced updatecurrentbookmark after unbundle, but that path might end up taking a wlock after lock when writing the bookmarks.

cleanup: replace naked excepts with except Exception: ...

cleanup: replace naked excepts with more specific ones

cleanup: "raise SomeException()" -> "raise SomeException"

cleanup: "not x in y" -> "x not in y"

cleanup: replace hasattr() usage with getattr() in hghave

cleanup: "x != None" -> "x is not None"

cleanup: eradicate long lines

mq: qimport need wlock for --push - do that after releasing lock qimport locking was introduced for phases in 29ea059be33c.

tag: run commit hook when lock is released (issue3344)

parsers: strictly check for 20-byte hashes where they're required

templater: handle SyntaxError when parsing ui.logtemplate Before, Mercurial would crash with a traceback ending with SyntaxError: unmatched quotes if you configured [ui] logtemplate = {rev}\n The SyntaxError is now catched and the string is re-parsed without requiring quotes.

i18n-pt_BR: synchronized with 95ca6c8b38da

progress: fix indentation

test-progress: fix whitespace typo

tests: unify the last sh tests This requires a slightly smarter check-code check for sed output filtering.

tests: run most check-code sh checks on continued lines too Some false errors are degraded to warnings and whitelisted.
