Added signature for changeset 5a8b54201039

Added tag 6.5.2 for changeset 5a8b54201039

relnotes: add 6.5.2

run-tests: detect HGWITHRUSTEXT value Without this, some manual check in tests/test-dirstate.t could get confused by the lack of `rust` in module policy and break the test.

tests: avoid test environment affecting setup.py In particular [RHG_FALLBACK_EXECUTABLE] is being set prematurely, before rhg is built, but probably the rest of the env changes don't help, either.

setup: make the error "Unable to find a working hg binary" more informative The error message now shows the attempted hg commands and their stderr, to make it easier to investigate why things are not working. Here's an example output /!\ /!\ Unable to find a working hg binary /!\ Version cannot be extracted from the repository /!\ Re-run the setup once a first version is built /!\ Attempts: /!\ attempt #0: /!\ cmd: ['hg-missing', 'log', '-r.', '-Ttest'] /!\ exception: [Errno 2] No such file or directory: 'hg-missing': 'hg-missing' /!\ attempt #1: /!\ cmd: ['/usr/bin/python3', 'hg', 'log', '-r.', '-Ttest'] /!\ return code: 255 /!\ std output: /!\ std error: *** failed to import extension "topic": No module named 'topic' *** failed to import extension "evolve": No module named 'evolve' abort: accessing `dirstate-v2` repository without associated fast implementation. (check `hg help config.format.use-dirstate-v2` for details) /!\ /!\ Could not determine the Mercurial version /!\ You need to build a local version first /!\ Run `make local` and try again /!\

pycompat: drop usage of hasattr/getattr/setattr/delatt proxy The function remains to ease extensions transition, but we no longer use them in core.

safehasattr: drop usage in favor of hasattr The two functions should now be equivalent at least in their usage in core.

check-code: drop the `safehasattr` rule Since we no longer supports Python 2 we no longer needs to use a custom function to compensate the short comings of the global `hasattr` function in it. We cannot use the Python 3 `hasattr` function instead.

url: ignore some future pytype error As soon as we start using the builtins `hasattr` function, pytype will start getting confused about which types are available or not. So we ignore this error beforehand.

url: move the _generic_proxytunnel in the `has_https` block It is only used when https exists. If you stay out of the block, pytype complains that the type of its argument are not declared.

pycompat: deprecate using bytes Python2 has been dropped for a while, so lets comply to the signature of the global function. This open the way to drop the use of `pycompat.getattr` and company, and, especially, the associated `util.safehasattr`.

dynamic-import: use sysstr for importing extension and others This logic is used by extensions, and python hooks and merge-tools. All this logic eventually deals with native string (unicode in Python 3). This patch makes it handle `str` directly instead of relying on some pycompat low lever layer to do the conversion at the last minutes. We adjust the Python version filtering of a test as the output seems to be present with Python 3.7 too.

extension: check the command attributes using `sysstr` Since we are checking attributes, lets use the native representation instead of bytes.

extension: access special module members using sysstr These extensions variables and mapping are module attributes so they should be dealt with unicode `str` in Python 3. We move the part that deal with reading theses variable and checking their validity to use unicode `str` string.

sshpeer: convert command name to sysstr before accessing method Method name are `str` so we should pass them as `str`.

localrepo: purge filecache attribute using there unicode name This could be better, but that's a good step.

fastannotate: use sysstr to check for attribute presence We do not need bytes here.

fastannotate: use sysstr to deal with some attributes We are now Python3 only and attribute are always unicode string. So no needs to managed them using bytes.

hgweb: use sysstr to set attribute on diff option Attribute identifier should be `str` not `bytes`.

hgweb: use sysstr to get attribute on diff option Attribute identifier should be `str` not `bytes`.

diff-option: move attributes handling to sysstr Attributes are `str` and should be handled as such.

compression: use sysstr to specify attribute to fetch for priority These are attributes so they should be `str`.

smartset: set attribute using sysstr instead of bytes We do not needs bytes here.

cachedlocalrepo: use sysstr for attribute name of "file of interest" The first item is an attribute name, the second one is a filename. So the first one can (and should) be a `str`.

terse-status: use `sysstr` to specify attributes to set We use unicode string to specify attribute and we add a explicit char for the other usage.

path-suboption: deprecated specifying the attributes as bytes The known suboptions have been updated, so we can deprecated passing bytes in case some extensions use them.

path-suboption: use str for "_pushloc" suboptions That second argument refer to an attribute and do not needs to be bytes.

path-suboption: use str for "pushrev" suboptions That second argument refer to an attribute and do not needs to be bytes.
