Before this patch, revision numbers and hash values in "comparison"
page are gotten from not changelog but filelog.
Such filelog information is useful only for hgweb debugging, and may
confuse users.
This patch shows revision numbers and hash values gotten from
changelog in "comparison" page.
Before this patch, "parents" in pages for file doesn't show as same
parents as "hg parents -r REV FILE", when the specified file is not
modified in the specified revision.
For example, it is assumed that revision A, B and D change file "f".
changelog (A) ---> (B) ---> (C) ---> (D)
filelog "f" (x) ---> (y) ------------> (z)
"/file/D/f" invokes "webutil.parents()" with filectx(z) gotten from
changectx(D), and it returns changectx(B). This is as same result as
"hg parents -r D f".
In the other hand, "/file/C/f" invokes "webutil.parents()" with
filectx(y') gotten from changectx(C), and it returns changectx(A),
because filectx(y') is linked to changectx(B), and works like
filectx(y) in some cases.
In this case, revision B is hidden from users browsing file "f" in
revision C.
This patch shows as same parents as "hg parents -r REV FILE" in pages
for file, by making "webutil.parents()" return:
- "linkrev()"-ed revision only, if:
- specified context instance is "filectx" (because
"webutil.parents()" is invoked with changectx, too), and
- (1) the revision from which filectx is gotten and (2) the one to
which filectx is linked are different from each other
- revision gotten from "ctx.parents()", otherwise
Before this patch, "comparison" shows unexpected result, when the
specified file is not modified in the specified revision, even though
"diff" shows empty result.
When REV doesn't change specified FILE, "diff" shows:
"hg diff -c REV FILE"
but "comparison" shows:
"hg diff -c `hg parents -r REV FILE` FILE"
In other words, the former gets parent from changelog, but the latter
gets one from filelog.
This may confuse users browsing (and switching "diff" and
"comparison" of) files in the specified revision.
This patch makes "comparison" get parent from not filelog but
changelog, to show "hg diff -c REV FILE" in both "diff" and
"comparison" pages.
This gives all the benefits introduced before for file source view, namely
code selection without line numbers and correct indents, highlighting line
which is linked to, long lines wrapping.
Implementation strategy is also the same as for file source view: all the
lines are put in a sigle pre tag with span's for each line. Correct line
numbering (same as before this patch) is achieved with nested CSS counters.
The user interface introduced in 3ff83729b63f is not considered ready
for prime time yet. The internal code stays in place for custom template
usage. The feature is ultimately wanted and will be re-enabled soon. The
current issue is only related to the visual of the current interface.
During merge of branches, it is useful to compare merge results against
the two parents. This change adds this support to hgweb. To specify
which parent to compare to, use rev/12300:12345 where 12300 is a
parent changeset number. Two links are added to changeset web page so
that one can choose which parent to compare to.
Previously, the parents / children were computed relative to the cset of the
currently shown file, which was wrong and inconsistent with diff and others.
With this patch, the listed csets are those that contain changes to the
currently compared file, which don't necessarily have to be the direct parents
and children of the changeset itself.
The top-level 'comparison' template was not really needed, and it also caused a
traceback to be shown for inexistent files (as reported by Ross Lagerwall).
Getting rid of it makes the overall templating structure simpler and causes
invalid files to be handled nicely.
Adds new web command to the core, ``comparison``, which enables colorful
side-by-side change display, which for some might be much easier to work with
than the standard line diff output. The idea how to implement comes from the
SonicHq extension.
The web interface gets a new link to call the comparison functionality. It lets
users configure the amount of context lines around change blocks, or to show
full files - check help (also in this changeset) for details and defaults. The
setting in hgrc can be overridden by adding ``context=<value>`` to the request
query string. The comparison creates addressable lines, so as to enable sharing
links to specific lines, just as standard diff does.
Incorporates updates to all web related styles.
Known limitations:
* the column diff is done against the first parent, just as the standard diff
* this change allows examining diffs for single files only (as I am not sure if
examining the whole changeset in this way would be helpful)
* syntax highlighting of the output changes is not performed (enabling the
highlight extension has no influence on it)
Since chmod isn't supported on Windows (or vfat), I'm importing a here-doc
instead (<<EOF ..).
Option --bypass on import of the here-doc is required on Windows (or vfat) to
bypass the working directory (see hg help import). Not using --bypass would
lose the mode changing bits.
I've had to insert a --bypass on the preexisting import call futher down in the
test, because importing a patch with --exact and mode changes will fail on
Windows (and vfat).
As the point of this test is not to test commit, I'm using the import
procedure for all platforms unconditionally, that is, I'm intentionally not
keeping the original sequence of hg and chmod calls for platforms that support
exec either, which saves us having to insert an #if exec ... #else ... #endif.
get-with-headers.py took the http GET parameter as a command line parameter
that had to start with '/'. MSYS on windows will mangle such paths.
Instead of applying a workaround everywhere (such as an extra '/') we let
get-with-headers.py add the mandatory '/'. That is consistent with the
url path handling in the Mercurial url class.
A few tests sent 'GET ?cmd=...' which is invalid. They will now send 'GET
/?cmd=...'.
This will not enable any tests for being run on windows - only remove one
reason they were disabled.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
Previously, we were finding the most recent version of a file in a
changeset and comparing it against its first file parent. This was
wrong on three counts:
- it would show a diff in revisions where there was no change to a file
- it would show a diff when only the exec bit changed
- it would potentially compare against a much older changeset, which
could be very expensive if git-style rename detection was enabled
This compares the file in the current context with that context's
parent, which may result in an empty diff when looking at a file not
touched by the current changeset.
The changeset view may show several diff regions, one per file, and this patch
numbers each of them so that links produced by the filenodelink fragment can
reference each diff region produced by the diffblock fragment through the use
of the blockno variable made available to both of them. This permits
navigation to diff regions on the changeset page from the file list, and
where the :target pseudo-class is supported in browsers, permits selective
presentation of diffs, showing one at a time instead of potentially many in
what would otherwise be a very long page that is difficult to navigate.
While Chrome, Firefox, and IE 6+ support the current date format being
passed to Date(), Safari doesn't:
> new Date('Mon Oct 24 13:58:01 2011 +0200')
Invalid Date
However, the rfc822date format--officially supported by
ECMAScript[1]--does work:
> new Date('Mon, 24 Oct 2011 13:58:01 +0200')
Mon Oct 24 2011 04:58:01 GMT-0700 (PDT)
This change replaces all instances of {date|date} in HTML with
{date|rfc822date}. For elements that only have the "age" class,
there's no outward change for users with JavaScript enabled. For
elements with both the "age" and "date" classes, the full date
displayed uses the new format.
Tested in IE 6, Safari 5.1.1, Google Chrome 15, and Firefox 7.0.1.

The plus and minus characters are normally not the same width in a
non-monospace font, and this made the line length change when the
diffstat display was toggled.
The square brackets are not rendered in a monospace font to ensure
that they align with the parenthesis on the same line.
Displayed in a row of the changeset summary table, underneath the list of
files. When the page is loaded, only the diff summary is displayed. The full
diffstat is only displayed when the [+] link is selected.
This allow safe caching of the pages by the browser and still display the right
amount of elapsed time upon page refresh.
If javascript is disabled, absolute time is displayed, leaving it readable.
All the templates have been updated.
When issuing `hg pull -r REV` in a repo with no common ancestor with the
remote repo, the message 'requesting all changes' is printed, even though only
the changese that are ancestors of REV are actually requested. This can be
confusing for users (see
http://www.selenic.com/pipermail/mercurial/2010-October/035508.html).
This silences the message if (and only if) the '-r' option was passed.
