transaction: gather backupjournal logic together in the __init__ The initialisation of file-backup related variable were a bit scattered, we gather them together.

transaction: handle missing file in backupentries (instead of using entries) The case where a backup of a missing file was requested was previously handled by the 'entries' list. As the 'backupentries' is about to gain ability to backup files outside of '.hg/store', we want it to be able to handle the missing file too. Reminder: using 'addbackup' on a missing file means that such file needs to be deleted if we rollback the transaction.

test-hup: use ls instead of echo Having one file entry per line makes it easier to analyse diffs.

largefiles: move "copyalltostore" invocation into "markcommitted" Before this patch, while "hg convert", largefiles avoids copying largefiles in the working directory into the store area by combination of setting "repo._isconverting" in "mercurialsink{before|after}" and checking it in "copytostoreabsolute". This avoiding is needed while "hg convert", because converting doesn't update largefiles in the working directory. But this implementation is not efficient, because: - invocation in "markcommitted" can easily ensure updating largefiles in the working directory "markcommitted" is invoked only when new revision is committed via "commit" of "localrepository" (= with files in the working directory). On the other hand, "commitctx" may be invoked directly for in-memory committing. - committing without updating the working directory (e.g. "import --bypass") also needs this kind of avoiding For efficiency of this kind of avoiding, this patch does: - move "copyalltostore" invocation into "markcommitted" - remove meaningless procedures below: - hooking "mercurialsink{before|after}" to (un)set "repo._isconverting" - checking "repo._isconverting" in "copytostoreabsolute" This patch invokes "copyalltostore" also in "_commitcontext", because "_commitcontext" expects that largefiles in the working directory are copied into store area after "commitctx". In this case, the working directory is used as a kind of temporary area to write largefiles out, even though converted revisions are committed via "commitctx" (without updating normal files).

largefiles: avoid printing messages while transplanting by "_lfstatuswriters" Putting "lambda *msg, **opts: None" (= avoid printing messages always) into "_lfstatuswriters" while transplanting makes explicit passing "printmessage = False" for "updatelfiles()" useless. This patch also removes setting/unsetting "repo._istransplanting" in "overridetransplant", because there is no code path referring it.

largefiles: update standins only at the 1st commit of "transplant --continue" Before this patch, "hg transplant --continue" may record incorrect standins, because largefiles extension always avoid updating standins while transplanting, even though largefiles in the working directory may be modified manually at the 1st commit of "hg transplant --continue". But, on the other hand, updating standins should be avoided at subsequent commits for efficiency reason. To update standins only at the 1st commit of "hg transplant --continue", this patch uses "automatedcommithook", which updates standins by "lfutil.updatestandinsbymatch()" only at the 1st commit of resuming. Even after this patch, "repo._istransplanting = True" is still needed to avoid some status report while updating largefiles in "lfcommands.updatelfiles()". This is reason why this patch omits not "repo._istransplanting = True" in "overriderebase" but examination of "getattr(repo, "_istransplanting", False)" in "updatestandinsbymatch".

largefiles: avoid redundant "updatelfiles" invocation in "overridetransplant" At "hg transplant --merge REV", largefiles newly coming from the 2nd parent (= REV) are marked as "a"(dded) by "patch.patch()", and have to be marked as "n"(ormal) after commit. But until changeset 3100d1cbce32, such largefiles were still marked as "a" unexpectedly even after commit, because no additional entry is added to filelog of such largefiles and they aren't listed in "repo[newnode].files()" in this case: "newnode" is one of newly committed changeset (= result of "repo.commit()"). "updatelfiles" invocation in "overridetransplant" shadows this problem by forcibly synchronizing lfdirstate to dirstate. Now, "updatelfiles" invocation in "overridetransplant" is redundant, because changeset 3100d1cbce32 made "markcommitted" use "ctx.files()" to get targets of "synclfdirstate" instead of "repo[newnode].files()".
