run-tests: cleanup windows generation of the python / python3 pointeur They are no need to generate then in RUNTESTDIR and we don't need a python2 executable. (because not test ever use `python2` explicitly). This is probably still not perfect, but at least it is better. Differential Revision: https://phab.mercurial-scm.org/D11045

run-tests: always define a custom-bin directory We are always generating `python` / `python3` executable and we will soon often generate a `hg` executable. So let's always make it a thing. This will help us to make sure we have the appropriate binary available to all script. On both linux and Windows. Differential Revision: https://phab.mercurial-scm.org/D11044

run-tests: explicitly track that `pythondir` was inferred If we want to know that something happened, we should simply track that this things happened. This will be useful to start using `tmpbindir` more in a different form. Differential Revision: https://phab.mercurial-scm.org/D11043

run-tests: use a global WINDOWS constant instead of multiple tests This should make the code clearer. This required the adjustement of a hack in the code testing this code. Differential Revision: https://phab.mercurial-scm.org/D11041

test-run-test: use explicit variables to clarify paths Since $TESTTMP and $TESTDIR are defined for both the main scope and the test run during the test, the situation get confusing. To work around that, we define some new, explicit, variables with the values we needs to keep track of. Differential Revision: https://phab.mercurial-scm.org/D11034

run-tests: also catch double-escapes for $TESTTMP On Windows the `$TESTTMP` string "repr" is different than its value, because `\` become `\\`. We introduce a new `$STR_REPR_TESTTMP` substitution to match that too. Differential Revision: https://phab.mercurial-scm.org/D11001

ci-windows: introduce manual windows CI Note: most of the foundational work of this commit was done by Matt Harbison, but enough has changed that I don't feel comfortable sending this patch as his. In our quest to remove Python 2 from Mercurial, we need to get Windows CI going to check that Python 3 support is up to an acceptable standard. This is the first step: adding a manual step to run a full Windows CI, with a certain definition of "full" since some things are not installed yet, like SVN. Differential Revision: https://phab.mercurial-scm.org/D11025

dirstate-item: deprecate tuple access on the class This should help us to catch and update the last user of this, especially in extensions. People will need to run the test with --pure to actually catch it, but this is better than nothing. Differential Revision: https://phab.mercurial-scm.org/D10992

dirstate-item: use the v1_serialization method in debugstate I am assuming the debug command are looking into the serialized format so I am using the `v1_` variants. This assumption might be wrong. Differential Revision: https://phab.mercurial-scm.org/D10988

dirstate-item: also build DistateItem in dirstate.directories() The rust code was building tuple. Differential Revision: https://phab.mercurial-scm.org/D10983

parsers: move DirstateItem to attr.s This is the followup I requested on D10949 - it was easy, so I just did it. Differential Revision: https://phab.mercurial-scm.org/D11030

cmdutil: fix newandmodified file accounting for --interactive commits `originalchunks` is a misleading name, because it only contains header objects, which are flattened to selected hunks by the filter function. As such, `chunks not in originalchunks` is always True and misleading, because hunk objects never compare equal to header objects. This change fixes the internal naming and removes the useless parameter from the method. This change also fixes issue6533, by considering the filtered headers, rather than the hunks, when determining new and modified files. If a file is renamed + edited, and the edited hunks are deselected (but the file is not), the filtered chunks will contain a header for the file (because it's .special()) but but no hunks.

test-run-tests: add missing backslash for Windows Differential Revision: https://phab.mercurial-scm.org/D11004

windows: use cpu-intensive task instead of real time in test Windows profiling breaks when using real time instead of cpu, but we need the extension function to show up, so make it do something instead of waiting. I've also duplicated the test cases so that explicit real and CPU times are tested (on platforms other than Windows) Differential Revision: https://phab.mercurial-scm.org/D11003

windows: use shell function instead of variable substitution This makes it compatible with Windows Differential Revision: https://phab.mercurial-scm.org/D11002

compat: normalise path before comparison in revlog splitting test This fixes the test on Window. Differential Revision: https://phab.mercurial-scm.org/D10999

windows: replicate the normalizing behavior of os.environ On Windows, `os.environ` normalizes environment variables to uppercase. Our current bytes-based environ substitution object is a simple dict, so we add the normalization behavior. This fixes test-http-peer.t on Windows. Differential Revision: https://phab.mercurial-scm.org/D10998

encoding: move case-related utils up This will be useful for the next commit that needs this code earlier. Differential Revision: https://phab.mercurial-scm.org/D11024

dirstate: drop the last explicit `state` usage in the module The internal detail of the `state` bytes is not longer exposed to the dirstate layer. Differential Revision: https://phab.mercurial-scm.org/D10977

test: use a python script in `test-transaction-rollback-on-sigpipe.t` This still does not work on Windows, but at least this is a python script now. Differential Revision: https://phab.mercurial-scm.org/D10947

test: make sure we hit the SIGPIPE in test-transaction-rollback-on-sigpipe With a coming change, we might not hit the sig pipe without issue and extra line of output. We do this early to make the next change clearer. Differential Revision: https://phab.mercurial-scm.org/D10946

test: clarify some output in `test-transaction-rollback-on-sigpipe` We don't want a dirty transaction to remain, but need to check the transaction was aborted. Otherwise it is easy to have no abandoned transaction if the transaction succeed. Differential Revision: https://phab.mercurial-scm.org/D10945

tests: add test case for issue 6262 If you split a commit, prune one of the sides, and then try to revive that commit by adding a successor, it will incorrectly be considered divergence. Differential Revision: https://phab.mercurial-scm.org/D10916

rewriteutil: look up common predecessor on unfiltered repo Before this patch, the code looking for divergence could crash when tried to look up a common predecessor in the filtered repo. This patch fixes that by looking up the common predecessor in an unfiltered repo. Differential Revision: https://phab.mercurial-scm.org/D10917

tests: demonstrate crash when common predecessor of divergence is hidden Differential Revision: https://phab.mercurial-scm.org/D11009

shallowutil: dedent code after the previous change Differential Revision: https://phab.mercurial-scm.org/D11008

shallowutil: narrow scope of try/except block This will make this code easier to understand in the future. Differential Revision: https://phab.mercurial-scm.org/D11007

remotefilelog: stop using RuntimeError for control flow We introduce a new exception to handle the various failure categories, rather than relying on RuntimeError. Differential Revision: https://phab.mercurial-scm.org/D11006

remotefilelog: tweak corrupt cache test to grep more flexibly I'm about to fix the abuse of RuntimeError here, which breaks the test if I don't do this. Differential Revision: https://phab.mercurial-scm.org/D11005

dirstatenonnormalcheck: fix some bytes formating on python3 Passing any object to `%s` no longer works, we need to explicitely convert the representation to bytes. Differential Revision: https://phab.mercurial-scm.org/D10993

dirstate-item: use the properties in `contrib/dirstatenonnormalcheck.py` Differential Revision: https://phab.mercurial-scm.org/D10991

dirstate-item: use the properties in largefiles I am now sure what large file is doing with then, but at least it is no longer using the tuple API to access data. Differential Revision: https://phab.mercurial-scm.org/D10990

dirstate-item: use the `state` property in debugpathcomplete Ideally we would use narrower property, but this is a good start. Differential Revision: https://phab.mercurial-scm.org/D10989

dirstate-item: use the properties in fakedirstatewritetime Differential Revision: https://phab.mercurial-scm.org/D10987

dirstate-item: use the properties in dirstatemap Differential Revision: https://phab.mercurial-scm.org/D10986

dirstate-item: use the properties in pathutil Differential Revision: https://phab.mercurial-scm.org/D10985

dirstate-item: use need_delay when packing dirstate Differential Revision: https://phab.mercurial-scm.org/D10984

dirstate-item: rename the class to DirstateItem The object is no longer a tuple, so it seems clearer to rename it (and its associated method) Differential Revision: https://phab.mercurial-scm.org/D10982

dirstate-entry: add a `mtime` property This is clearer than "tuple" indexing. Differential Revision: https://phab.mercurial-scm.org/D10981

dirstate-entry: add a `size` property This is clearer than "tuple" indexing. Differential Revision: https://phab.mercurial-scm.org/D10980

dirstate-entry: add a `mode` property This is clearer than "tuple" indexing. Differential Revision: https://phab.mercurial-scm.org/D10979

dirstate: no longer pass `oldstate` to the `dropfile` The `oldstate` value come literally from `_map` so we don't need to pass tha information along. Differential Revision: https://phab.mercurial-scm.org/D10978

dirstate: drop last explicite `state` usage in status Given that the previous conditional we can safely use `tracked` here. Differential Revision: https://phab.mercurial-scm.org/D10976

dirstate: reorder "state" checking conditional This is easier to read and will make this simpler to update in the next changeset. Differential Revision: https://phab.mercurial-scm.org/D10975

dirstate-entry: add a `need_delay` method This abstract the internal processing need for entry that would have an ambiguous mtime (If I understand things correctly). Differential Revision: https://phab.mercurial-scm.org/D10974

dirstate-entry: add a `tracked` property This abstract the individual `state` value and has a clear semantic. Differential Revision: https://phab.mercurial-scm.org/D10973

dirstate: drop `state` to `_addpath` All its value are inferred within the dirstatemap now. Differential Revision: https://phab.mercurial-scm.org/D10972

dirstate: infer the 'n' state from `from_p2` This flag is only used with 'n' so lets set the state based on that parameter in this case. Differential Revision: https://phab.mercurial-scm.org/D10971
