osx: explicitly build hg with /usr/bin/python2.7 This should help avoid creating a package that depends on a custom Python, as happened when I built a package for 3.8.

osx: correct comment about ordering of welcome page

osx: jettison outdated build instructions

commandserver: extract _cleanup() hook to clarify chg is doing differently This makes it clear that chg needs its own way to unlink closed socket file. I made a mistake in draft patches without noting the difference.

chgserver: drop repo at chgunixservice.__init__() Since it isn't expensive operation, we don't have to delay it to init().

chgserver: extract utility to bind unix domain socket to long path This is common problem of using sockaddr_un.

chgserver: narrow scope of chdir() to socket.bind() This helps extracting a utility function.

annotate: handle empty files earlier Rather than looping on funcmap and then checking for non-zero `l` continue if the result of fctx.annotate is empty.

context: eliminate handling of linenumber being None in annotate I could not find any use of this parameter value. And it arguably makes understanding of the function more difficult. Setting the parameter default value to False.

tests: regenerate x509 test certificates The old x509 test certificates were using cryptographic settings that are ancient by today's standards, namely 512 bit RSA keys. To put things in perspective, browsers have been dropping support for 1024 bit RSA keys. I think it is important that tests match the realities of the times. And 2048 bit RSA keys with SHA-2 hashing are what the world is moving to. This patch replaces all the x509 certificates with new versions using modern best practices. In addition, the docs for generating the keys have been updated, as the existing docs left out a few steps, namely how to generate certs that were not active yet or expired.

hgweb: add a link on node id in annotate hover-box The link pointing the annotate view at this revision, just like the one in the left-column but accessible from anywhere.

hgweb: move author information from left-column to hover-box in annotate view And display the full author information since there is enough space there.

hgweb: add links to diff and changeset in hover-box on annotate view

hgweb: add link to parents of annotated revision in annotate view The link is embedded into a div with class="annotate-info" that only shows up upon hover of the annotate column. To avoid duplicate hover-overs (this new one and the one coming from link's title), drop "title" attribute from a element and put it in the annotate-info element.

compat: provide a declaration of ssize_t, for MS windows

check-code: enforce (glob) on output lines containing 127.0.0.1

tests: add (glob) annotations to output lines with 127.0.0.1

run-tests: add support for using 127.0.0.1 as a glob Some systems don't have a 127/8 address for localhost (I noticed this on a FreeBSD jail). In order to work around this, use 127.0.0.1 as a glob pattern. A future commit will update needed output lines and add a requirement to check-code.py.

check-code: only treat a # as a line in a t-test if it has a space before it Prior to this, check-code wouldn't notice things like (glob) annotations or similar in a test if they were after a # anywhere in the line. This resolves a defect in a future change, and also exposed a couple of small spots that needed some attention.

test-export: be more aggressive about quoting ^ An upcoming change to check-code will notice this isn't quoted enough. Presumably it's been fine by luck all this time.

test-check-shbang: work around check-code not wanting hardcoded paths I'm about to fix a bug in check-code that a # anywhere on a line treated the rest of the line as a comment, even if it was meaningful. This test is the one place we explicitly *do* want hardcoded paths referenced, but we can work around that by specifying bin as a regular expression.

tests: relax "Connection refused" match We already had the match relaxed on Windows, but on Google Compute Engine VMs I'm seeing "Network is unreachable" instead of "Connection refused". At this point, just give up and make sure we get an error back.

commandserver: backport handling of forking server from chgserver This is common between chg and vanilla forking server, so move it to commandserver and unify handle(). It would be debatable whether we really need gc.collect() or not, but that is beyond the scope of this series. Maybe we can remove gc.collect() once all resource deallocations are switched to context manager.

commandserver: promote .cleanup() hook from chgserver This allows us to unify _requesthandler.handle().
