branchmap: avoid changelog and attribute lookups in replacecache() This should make things faster. I'm not sure which operations would benefit from it though. Maybe branchmap application on clone? Differential Revision: https://phab.mercurial-scm.org/D5162

branchmap: pass changelog into branchmap functions As part of building the branchmap, we loop over revs and call branchmap() or _branchmap(). Previously, these functions were accessing repo.changelog. We know from past experience that repo.changelog in loops is bad for performance. This commit teaches the branchmap code to pass a changelog instance into branchmap() and _branchmap() so we don't need to pay this penalty. On my MBP, this appears to show a speedup on a clone of the mozilla-unified repo: $ hg perfbranchmap --clear-revbranch ! base ! wall 21.078160 comb 21.070000 user 20.920000 sys 0.150000 (best of 3) ! wall 20.574682 comb 20.560000 user 20.400000 sys 0.160000 (best of 3) $ hg perfbranchmap ! base ! wall 4.880413 comb 4.870000 user 4.860000 sys 0.010000 (best of 3) ! wall 4.573968 comb 4.560000 user 4.550000 sys 0.010000 (best of 3) Differential Revision: https://phab.mercurial-scm.org/D5161

fuzz: move many initialization steps into LLVMFuzzerInitialize Doing this means that things we intentionally leak (eg type objects) no longer confuse AddressSanitizer, so now we can run the fuzzer MUCH longer. Differential Revision: https://phab.mercurial-scm.org/D5154

bundle2: fix broken compression engine assertion bundletype() is a function, so it needs to be called, and it is documented to return a 2-tuple. This code is untested, so that's why we haven't noticed the bad assertion. Differential Revision: https://phab.mercurial-scm.org/D5155

tests: glob over a difference between Windows 7 and Window 10 The error value is 11001 on Windows 10. I have no idea why it changed, but it seems unimportant.

py3: fix module imports in test-highlight.t The hash changes are because the *.py file is committed to the repo.

py3: fix module imports in tests, as flagged by test-check-module-imports.t I have no idea why these aren't flagged with python2. I excluded test-highlight.t for now to make this easier to review- the changed code is committed to a repo, which has cascading changes on the rest of the test. There's a mix of bytes and str in the imports dict of contrib/import-checker.py that crashed it half way through listing out these errors. I couldn't figure out how to fix that properly, so I was lazy and applied this on py3, to find the rest of the errors: diff --git a/contrib/import-checker.py b/contrib/import-checker.py --- a/contrib/import-checker.py +++ b/contrib/import-checker.py @@ -626,7 +626,12 @@ def find_cycles(imports): top.foo -> top.qux -> top.foo """ cycles = set() - for mod in sorted(imports.keys()): + def sort(v): + if isinstance(v, bytes): + return v.decode('ascii') + return v + + for mod in sorted(imports.keys(), key=sort): try: checkmod(mod, imports) except CircularImport as e:

lfs: don't add extension to hgrc after conversion (BC) This is in the spirit of bcf72d7b1524.

addremove: add "ui." prefix to message color keys I don't like fully-colorized status/warning messages, and I want to disable them at all. If we'd supported a syntax like 'color.ui.*=none', I could easily turn addremove.added/removed off as well as ui.error. This patch is just for that. Since addremove colors aren't released yet, which were added at ddc1da134772, there are no compatibility concerns.

update: clarify update() call sites by specifying argument names merge.update() takes a lot of parameters and I get confused all the time which is which. Differential Revision: https://phab.mercurial-scm.org/D5153

debugcommands: avoid stack trace from debugindexstats in pure mode This has been broken since I added it in d71e0ba34d9b (debugcommands: add a debugindexstats command, 2018-08-08). This patch also fixes the test. Differential Revision: https://phab.mercurial-scm.org/D5152

tests: fix up pure case of test-sqlitestore.t This is clearly what the line should read based on the "force to zlib" section below, so I'm guessing it just got overlooked during development. Differential Revision: https://phab.mercurial-scm.org/D5151

tests: don't emit false failures when sqlite3 is missing I'm honestly surprised we have buildbot coverage for this, but we do! Differential Revision: https://phab.mercurial-scm.org/D5150

py3: get around IOError variants in test-commandserver.t

py3: don't use traceback.print_exc() in commandserver.py It doesn't support a bytes stream on Python 3. This makes a traceback being sent by one frame, but that shouldn't matter.

py3: invalidate repository cache with system-string keys # skip-blame just a few r'' prefixes

py3: system-stringify file mode in commandserver.py # skip-blame just r'' prefixes

py3: alias next to __next__ in commandserver.py

py3: system-stringify list of attributes to be forwarded from commandserver.py # skip-blame just some r'' prefixes

py3: import StringIO from test utility to test-commandserver.t

py3: use bprint() helper in test-commandserver.t

py3: byte-stringify most literals in test-commandserver.t print() calls will be replaced by bprint(). # skip-blame just tons of b'' prefixes.

localrepo: ensure we properly %-format int in exception throw I'm not thrilled with this, but it'll do. Differential Revision: https://phab.mercurial-scm.org/D5107
