For example, ":hg:`help config.default-push`" creates an invalid link
to "hgrc.5.html#default-push" in HTML, but ":hg:`help
config.paths.default-push`" creates a valid link to
"hgrc.5.html#paths".
Before this patch, ":hg:`help config.SECTION`" in online help text is
translated to a link to "hg.1.html#config.SECTION" in HTML
unintentionally.
This patch translates from :hg:`help config.SECTION` in online help
text to a valid link to "hgrc.5.html#SECTION" in HTML.
This patch ignores element(s) under "SECTION" (e.g. "ITEM" of
":hg:`help config.SECTION.ITEM`"), because there is no way to refer
directly to it in HTML, yet.
Before this patch, ":hg:`help config`" in online help text is
translated to a link to "hg.1.html#config" in HTML, even though actual
"hg help config" shows not help for "hg config" command but "config"
help topic, and all of current ":hg:`help config`" expects the latter.
This patch translates from ":hg:`help config`" in online help text to
a link to "hgrc.5.html" in HTML as expected.
This patch also allows ":hg:`help -c COMMAND`" style to link
"hg.1.html#COMMAND" for readability.
Before this patch, line number in source of the message to be
translated is wrong in hg.pot, if corresponded message is placed after
".. DIRECTIVE::", because number of lines related to such directive
isn't added to variable "delta", which holds number of untranslated
lines in given text.
This patch always adds "2" to "delta", because text block is split
into translation units by "\n\n".
If the revset being benchmarked has an exception, the handling code was
encountering an error because the exception did not always have an "output"
attribute (I think it's a python 2.7 thing).
Previously, two changes that were nearly, but not quite, identical would result
in large merge conflict regions that looked very similar, and were thus very
confusing to users, and lead people used to other source control systems to
claim that "mercurial's merge algorithms suck". In the relatively common case
of a new file being introduced in two branches with very slight modifications,
the old behavior would show the entire file as a conflict, and it would be very
difficult for a user to determine what was going on.
In the past, mercurial attempted to solve this with a "very smart" algorithm
that would find all common lines, but this has significant problems as
described in 3d22d20aa950.
Instead, we use a "very dumb" algorithm introduced in the previous patch that
simply matches lines at the periphery of conflict regions. This minimizes most
conflict regions well, though there may still be some degenerate edge cases,
like small modification to the beginning and end of a large file.
This is necessary for hgweb to embed JSON data in HTML. JSON data must be
able to be embedded in non-UTF-8 HTML page so long as the page encoding is
compatible with ASCII.
According to RFC 7159, non-BMP character is represented as UTF-16 surrogate
pair. This function first splits an input string into an array of UTF-16
code points.
https://tools.ietf.org/html/rfc7159.html#section-7
This makes jsonescape() a thread-safe function, which is necessary for hgweb.
The initialization stuff isn't that slow:
$ python -m timeit -n1000 -s 'from mercurial import encoding as x' 'reload(x)'
original: 1000 loops, best of 3: 158 usec per loop
this patch: 1000 loops, best of 3: 214 usec per loop
compared to loading the commands module:
$ python -m timeit -n1000 -s 'from mercurial import commands as x' 'reload(x)'
1000 loops, best of 3: 1.11 msec per loop
This is slightly faster and convenient to implement a paranoid escaping.
$ python -m timeit \
-s 'from mercurial import encoding; data = str(bytearray(xrange(128)))' \
'encoding.jsonescape(data)'
original: 100000 loops, best of 3: 15.1 usec per loop
this patch: 100000 loops, best of 3: 13.7 usec per loop
Bare 'hg update' now brings you to the tipmost descendant (on the same branch).
Leaving the user on the same topological branch. The previous behavior, updating
to the tipmost changeset on the same branch could lead to jump from a
topological branch to another. This was confusing and impractical. As the only
conceivable reason for the old behavior have been address by the recently
introduce message about other heads, we can "safely" change this behavior
All test changes have been reviewed and seen a valid consequences.
The --update is unrelated to the test and has no effect as it fails anyway.
Dropping it reduces the noise in the coming change in default destination for
update.
Not all external extensions provide docs; if you use such an extension, you
will experience a crash if you use "hg help --keyword <word>", and <word>
happens to match the extension name.
With an ignore pattern containing a '/' and a Windows style path containing '\',
status was properly ignoring the file, but debugignore was stating that it
wasn't ignored.
This rule detects "hg extdiff" invocation without -p/--program and
-o/--option.
This patch specifies "-p diff" explicitly in test-extdiff.t to avoid
false positive matching.
Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because of incompatibility of
"diff" command and its output.
For example, system standard "diff" (= /usr/bin/diff) on Solaris
differs from GNU diff in points below:
- "-N" (treat absent files as empty) option isn't supported
- files are examined not in dictionary order
(maybe, in order in storage)
This patch introduces portable diff script "pdiff" and make tests use
it via extdiff extension.
For portability of tests, this patch invokes "pdiff" script with
explicit "sh", because standard shell of runtime platform ("cmd.exe"
on Windows) is used at first to invoke external diff command.
With -n/--test and if the PAGER environment variable is set, 'hg email' send its
output to the user defined pager.
If the pager capture the output, the test is unable verify it.
Unsetting the PAGER environment variable force 'hg email' to write to stdout.
Before this patch, check-code examines "magic" pattern (e.g.
'^#!.*python') matching against not contents of a file, but name of
it.
This unintentionally omits code checking against Python source file,
of which filename doesn't end with "*.py" or "*.cgi", even though
contents of it starts with "#!/bin/python" or so.
In this change, 'pre' refers contents of file 'f'.

Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because system standard "diff" (=
/usr/bin/diff) on Solaris always generates chunk headers below:
- "@@ -1,0 +1,nnnn @@" for added file
- "@@ -1,nnnn +1,0 @@" for removed file
even though "diff" on Linux generates:
- "@@ -0,0 +1,nnnn @@" for added file
- "@@ -1,nnnn +0,0 @@" for removed file
This patch makes chunk header of external diff glob-ed for portability
of tests.
"hg diff" output follows Linux style, and there are many such diff
output lines in existing tests. This is reason why this patch doesn't
add check-code.py any rule to detect such diff output in tests.
This patch is a part of making tests using external "diff" portable,
and test-subrepo-deep-nested-change.t isn't yet portable even after
this patch.
Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because system standard "diff" (=

below:
@@ -X.x +Y.y @@
even though "diff" on Linux sometimes omits ".x" and/or ".y" in it.
This patch makes chunk header of external diff glob-ed for portability
of tests, and adds check-code.py rules to detect such diff output in
tests.
This patch also changes "hg diff" output in test-subrepo-git to
simplify detection rules, even though it is certainly portable because
these lines are generated by "git" command.

Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because system standard "diff" (=

This patch makes timezone in external diff output glob-ed for

Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because "-p" (show which C function
each change is in) option isn't supported by system standard "diff" on
Solaris, even though extdiff passes it to external "diff" by default.
Fortunately, this non-portable option isn't important for (current, at
least) tests using external "diff" command via extdiff extension.
This patch omits "-p" for external "diff" command via extdiff
extension for portability of tests, and adds check-code.py a rule to
detect invocation of "diff" with "-p".
Newly added check-code.py rule examines only lines generated by
external "diff" with "-r", because strict examination might
misidentify "hg diff -p" or other complicated lines consisting of
"diff" string as wrong one.

When I taught debugrebuildfncache about dirlogs in ebe9dacc63ba
(treemanifests: fix streaming clone, 2016-02-04), I added a
last-minute "if 'treemanifest' in repo" guard. That should have been
checking for "... in repo.requirements". Fix that and add tests for
it.
A concern around the user experience of Mercurial is user getting stuck on there
own topological branch forever. For example, someone pulling another topological
branch, missing that message in pull asking them to merge and getting stuck on
there own local branch.
The current way to "address" this concern was for bare 'hg update' to target the
tipmost (also latest pulled) changesets and complain when the update was not
linear. That way, failure to merge newly pulled changesets would result in some
kind of failure.
Yet the failure was quite obscure, not working in all cases (eg: commit right
after pull) and the behavior was very impractical in the common case
(eg: issue4673).
To be able to change that behavior, we need to provide other ways to alert a
user stucks on one of many topological head. We do so with an extra message after
bare update:
1 other heads for branch "default"
Bookmark get its own special version:
1 other divergent bookmarks for "foobar"
There is significant room to improve the message itself, and we should augment
it with hint about how to see theses other heads or handle the situation (see
in-line comment). But having "a" message is already a significant improvement
compared to the existing situation. Once we have it we can iterate on a better
version of it. As having such message is an important step toward changing the
default destination for update and other nicety, I would like to move forward
quickly on getting such message.
This was discussed during London - October 2015 Sprint.
With util.getpid, it is now possible to define fixed pids.
Future iterations can define a map of pids on a locked
first come first serve basis to create a more realistic
harness, but for now this is good enough.
This applies to blackbox, but could apply to other
tests as well.
Without this, when there are multiple ui views, each blackbox
will have its own file handle, and the logging will be in
a really bad order.
Also, because of the way blackbox works, it never closes its
file handles, which means the last output before exit is
often lost.
While it is not easy to make a file 000 on Windows, you can
emulate most of the behaviors by replacing the file with a directory.
Also corrects test description to properly indicate that failing to
read from the log is fatal.
These options were undocumented for 3.7 because of an issue found during the
freeze (see rev e5c26e4e6ec7). This issue has now been fixed, so we can
document these options again.
