bundlespec: test if the "obsolete=" parameter is read Narrator voice: Actually it is not. We will fix it in the next changeset.

bundlespec: fix lack of title in a evolve tests This is a full new test case and should be "flagged" as such.

bundlespec: make the `stream` case less special The handling of the stream case seems fragile (does not account for newer parts and options that will arise) and has special code dedicated to it. To simplify and strengthen things, we make it use the same mechanism as the other options. So we make it less special by making it a special value in the common case.

bundlespec: phase out the `_bundlespeccgversions` mapping The `_bundlespeccgversions` mapping is redundant with the `cg.version` parameter. We move all users to the `cg.version` version and phase out the `_bundlespeccgversions` mapping.

commit: allow to close branch when committing change over a closed head Otherwise, an explicit other commit become necessary, which seems both silly and verbose. This is useful when merging closed heads on the same branches, for example when merging multiple repositories together.

typing: add a missing suppression directive for `msvcrt`

windows: drop some py2 compatibility code The comment was wrong- the exception handler was the py3 case.

windows: prevent bytes from being passed to registry APIs There was a TortoiseHg bug report in this area[1], and from inspection, it looks like passing `b""` as `valname` would fail to convert to unicode. The underlying API allows both `""` and `NULL` to return the default value for the key. [1] https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5803

relnotes: add 6.1.3

logcmdutil: use the same data as {file*} template keywords (issue6642) Since 0c72eddb4be5 template keywords that show files use a different source of data than ctx.p1().status(ctx). These two functions in logcmdutil also show file lists when needed (e.g. log with --debug flag), but previously they used the old way of just looking at status compared to p1 and it resulted in differences between e.g. hg log --debug and hg log -T '{file*}'. test-phases.t needs an adjustment because 7 is a merge commit of two topological branches and one of them introduces files C, D and E.

tests: show that hg log --debug output differs from {file*} template keywords hg log --debug -T xml doesn't differ, but let's test it because we can.

cleanup: return directly instead of assigning variable

commit: remove special handling of IOError (actually dead code) In the past, IOError was used to mark a file as removed. The differentiation between OSError and IOError in this place was introduced in e553a425751d, to avoid that “normal” OSErrors / IOErrors accidentally mark files as removed. This weird internal API was removed in 650b5b6e75ed. It seems like that changeset should have removed the differentiation, at least I don’t see any reason for keeping it. On Python 3, OSError and IOError are aliased. Therefore the removed code was actually dead.

py3: catch specific OSError subclasses instead of checking errno On Python 3, the "not a directory" error is mapped to ENOTDIR instead of EINVAL. Therefore, catching the NotADirectoryError subclass is sufficient.

py3: catch specific OSError subclasses instead of checking errno Contrary to the previous changesets in this series, this covers cases where errno was checked for multiple values. EACCES -> PermissionError ENOENT -> FileNotFoundError ENOTDIR -> NotADirectoryError EISDIR -> IsADirectoryError

py3: catch ProcessLookupError instead of checking errno == ESRCH

py3: catch PermissionError instead of checking errno == EPERM

py3: catch PermissionError instead of checking errno == EACCES

py3: catch FileNotFoundError instead of checking errno == ENOENT

py3: catch FileExistsError instead of checking errno == EEXIST

py3: catch BrokenPipeError instead of checking errno == EPIPE

py3: catch ChildProcessError instead of checking errno == ECHILD

py3: remove retry on EINTR errno Since the implementation of PEP 475 (Python 3.5), Python retries system calls failing with EINTR. Therefore we don’t need the logic that retries it in Python code.

py3: stop catching TypeError that was raised on Python 2

py3: use `x.hex()` instead of `pycompat.sysstr(node.hex(x))`

tests: assume that `raw` attribute is present on original socket file object It seems like the original socket file object is always an io.BufferedIO instance. If not, the code will fail and we should try harder to get the socket object (e.g. if the original socket file object is unbuffered, we can get the `_sock` attribute directly from it).

tests: constant-fold a `pycompat.ispy3` in testlib/badserverext.py

tests: remove Python 2 special cases in test-stdio.py

py3: remove dead code to make file descriptors non-inheritable On Python 3, file descriptors are already non-inheritable by default.

py3: remove hack that removed flush argument from print() calls on Python 2
