docker: avoid /tmp write access issues by fixing permissions

url: raise error if CONNECT request to proxy was unsuccessful The deleted code didn’t work on Python 3. On Python 2 (or Python 3 after adapting it), the function returned in the error case. The subsequent creation of SSL socket fails during handshake with a nonsense error. Instead, the user should get an error of what went wrong. I don’t see how the deleted code would be useful in the error case. The new code is also closer of what the standard library is doing nowadays that it has proxy support (which we don’t use in the moment). In the test, I use port 0 because all the HGPORTs were already taken. In practice, there should not be any server listening on port 0.

revset: fix the doc of "nodefromfile" This should maybe be called "nodesfromfile", but at least the documentation is correct (it was previously a copy past from follow).

chg: replace mercurial.util.recvfds() by simpler pure Python implementation On Python 3, we have socket.socket.recvmsg(). This makes it possible to receive FDs in pure Python code. The new code behaves like the previous implementations, except that it’s more strict about the format of the ancillary data. This works because we know in which format the FDs are passed. Because the code is (and always has been) specific to chg (payload is 1 byte, number of passed FDs is limited) and we now have only one implementation and the code is very short, I decided to stop exposing a function in mercurial.util. Note on terminology: The SCM_RIGHTS mechanism is used to share open file descriptions to another process over a socket. The sending side passes an array of file descriptors and the receiving side receives an array of file descriptors. The file descriptors are different in general on both sides but refer to the same open file descriptions. The two terms are often conflated, even in the official documentation. That’s why I used “FD” above, which could mean both “file descriptor” and “file description”.

py3: don’t subscript socket.error On Python 2, socket.error was subscriptable. On Python 3, socket.error is an alias to OSError and is not subscriptable. The except block passes the exception to self.send_error(). This fails on both Python 2 (if it was executed) and Python 3, as it expects a string. Getting the attribute .strerror works on Python 2 and Python 3, and has the same effect as the previous code on Python 2.

parsers: drop one extra argument to PyErr_Format GCC gave the following warning during `make local`: mercurial/cext/parsers.c: In function 'dirstate_item_from_v1_data': mercurial/cext/parsers.c:413:30: warning: too many arguments for format [-Wformat-extra-args] 413 | "unknown state: `%c` (%d, %d, %d)", state, mode, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To reproduce, you might need to add the -Wformat-extra-args flag, because it isn't present for me when building for the default python3. But I can see this warning while simply building 6.1 with `make PYTHON=python2 clean local`. I don't think this NULL was useful, because other instances of PyErr_Format() don't have any NULLs as the final argument, but keep in mind that I don't know python's C API.

demandimport: eagerly load msvcrt module on PyPy

search-discovery-case: update documentation of a function We return data, it is simpler when we know what these data means.

ci: drop the phabricator refresh step Now that phabricator is no longer in us, we should avoid this useless step to save time and simplify things.

worker: avoid potential partial write of pickled data Previously, the code wrote the pickled data using os.write(). However, os.write() can write less bytes than passed to it. To trigger the problem, the pickled data had to be larger than 2147479552 bytes on my system. Instead, open a file object and pass it to pickle.dump(). This also has the advantage that it doesn’t buffer the whole pickled data in memory. Note that the opened file must be buffered because pickle doesn’t support unbuffered streams because unbuffered streams’ write() method might write less bytes than passed to it (like os.write()) but pickle.dump() relies on that all bytes are written (see https://github.com/python/cpython/issues/93050). The side effect of using a file object and a with statement is that wfd is explicitly closed now while it seems like before it was implicitly closed by process exit.

mr-template: drop the "title and description" I though I would affect the template in the menu itself, however it just a normal piece of text that should not be here.

hghave: make black version regex work with newer versions of black Black commit 117891878e5be4d6b771ae5de299e51b679cea27 (included in black >= 21.11b0) dropped the string "version " from the output of "black --version". To make the regex work with newer black versions, make matching of "version " optional.

debugindex: add a `rank` column

debugindex: add a `sd-chunk-size` column

debugindex: add a `sidedata-offset` column

debugindex: add a `sd-comp-mode` column

debugindex: add a `chunk-size` column

debugindex: add a `data-offset` column

debugindex: add a `comp-mode` column

debugindex: add a `flags` column

debugindex: add a `delta-base` column

debugindex: add a `full-size` column

debugindex: add a `p2-rev` column This will be useful in case of corrupted index.

debugindex: add a `p1-rev` column This will be useful in case of corrupted index.

debugindex: introduce a concept of "verbose-only" column We are about to add a bunch of new column and most of them are probably only relevant to --verbose. We add some more testing of the `--verbose` mode in a sidedata context.

debugindex: move to a flexible column Each column is now declared as a decorated function. This will make it much simpler to add more new column in the future.

debugindex: rename the parent column to mention nodeid We will add new columns with the "revnum" version of the parent. It will be useful in case we need to inspect a corrupted revlog index.

debugindex: align column name on the right It will be simpler to align everything on the same side, and the right seems a better side as it match the value alignment.

debugindex: move the logic into its own module Adding more information will significantly increase the amount of code. So we move the code into its own module before making it more complex.

debugindex: rename to debugindex debug-revlog-index The command dump some content of the revlog index and omit a lot of information. I am going to make it display the missing information. For clarity, we rename the command to explicitly mention revlog.
