This is a basic, hopefully portable, zeroconf extension.
Enabling it will allow hg paths/pull/push/clone/etc. to automatically
discover services advertised as "_hg".
And naturally, running hg serve will advertise itself as a "_hg"
service as well as a "_http" service for use by browsers.
Normcase already takes care of upper/lower case and /->\ conversions.
What's left for normpath is folding of a/../a sequences but this should
be either done consistently on both non-folding and folding code path
or not at all, otherwise we are introducing inconsistent behavior between the
two that has nothing to do with case folding.
Second argument against it - normpath being pure Python function is very slow -
as much as 50% of time is spend just inside normpath call on my repository.
This patch fixes regression reported in 1286 that causes util.fspath
to be called for every file not in current manifest - including ignored files.
The regression is quite severe - the time for simple hg st goes from 5s to 1m38s
on one of my source trees - which basically renders mercurial useless.
Previously, an unknown node id would lead to the following error:
abort: 00changelog.i@343445453433: no node!
All other unknown revision would instead display as:
abort: unknown revision '343445453'!
The former error message has been suppressed in favor of the latter.
1) In posix part set error when path is too long so instead of
SystemError: error returned without exception set
it will raise
ValueError: path too long
2) In Win32 part replace generic
PyErr_SetExcFromWindowsErrWithFilename
by
PyErr_SetFromWindowsErrWithFilename
The exception returned is WinError(based on OSError) and
some rudimentary errno translation is performed from Windows error range
to errno module friendly range so errors like ENOENT can be handled via symbolic
constant and consistently between Win32 and Posix.
Use information provided by FindFile... Win32 calls
to generate stat information without lstat call per file.
rwx bits in st_mode are ignored as they are not stored in Win32 fs
and Mercurial does not use them
Unicode path / path names over _MAX_PATH are intentionally not supported.
There is no technical reason to update it except it contains all the patches
already done in mercurial plus other stuff. It will be easier to update and
maintain in the future.
