convert: use splicemap entries when sorting revisions (
issue1748)
When sorting revisions before converting them, we have to edit the revision
graph using splicemap entries. Otherwise, a spliced revision may be converted
before its synthetic parents. Invalid splicemap revisions are now detected
before starting the conversion.
convert: turn splicemap into a simple dictionary
Parsing the splicemap as a mapfile was a pain because map does not let us
override its parsing code and splicemap entries are not key/values. Besides we
had no need for mapfiles extra features. Just parse the splicemap and return a
dictionary.
largefiles: only cache largefiles in new heads
This fixes a serious performance regression in largefiles introduced in
Mercurial 2.1. Caching new largefiles on pull is necessary, because
otherwise largefiles will be missing (and unable to be downloaded) when
the user tries to merge or rebase a new head with an old one. But this
is an expensive operation and should only be done for heads that are new
from the pull, rather than on all heads in the repository.
mq: restore _branchtags() fast path (
issue3223)
Since
a5917346c72e, mq saves the nodeid of the first applied patch to
cache/branchheads, which breaks the optimized cache handling introduced in
fbf8320f25c8. The problem is the revision being committed is appended to
mqrepo.applied after the commit succeeds, which means mqrepo._branchtags()
performs a regular update and write the first applied patch to the branch
cache.
One solution is to set a context variable _committingpatch on the mqrepo while
it is committing a patch and to take it in account when deciding to fast-path
mqrepo._branchtags(). Not really elegant but it works.
The changes to test-mq-caches.t reverse changes introduced by
a5917346c72e. The
cache should not have been updated with mq records.
The changes to test-keyword.t are indirectly caused by
a5917346c72e.

Notes:
- qpush still makes a slow path _branchtags() call when checking heads. Maybe
this can be optimized.
- be careful when merging this patch in default as secretcommit() was renamed
newcommit() right after the end of the code freeze.
mq: ensure all mq commits are made with secretcommit()
Having a common code path helps fixing things globally.
convert/bzr: ignore nested repos when listing branches (
issue3254)
Reported by A.S. Budden <abudden@gmail.com>
tests: tighten checks for octal escapes in shell printf.
printf on AIX default shell ksh (89) says \1 is an invalid escape. It insists
on at least 2 digits. This causes failures in test-keyword.t and test-status.t.
check-code.py already looks out for \NNN and recommends using Python
for outputting octal values. Extend the check to \NN and \N and fix up
resulting failures.
