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.
Send the command arguments in the HTTP headers. The command is still part
of the URL. If the server does not have the 'httpheader' capability, the
client will send the command arguments in the URL as it did previously.
Web servers typically allow more data to be placed within the headers than
in the URL, so this approach will:
- Avoid HTTP errors due to using a URL that is too large.
- Allow Mercurial to implement a more efficient wire protocol.
An alternate approach is to send the arguments as part of the request body.
This approach has been rejected because it requires the use of POST
requests, so it would break any existing configuration that relies on the
request type for authentication or caching.
Extensibility:
- The header size is provided by the server, which makes it possible to
introduce an hgrc setting for it.
- The client ignores the capability value after the first comma, which
allows more information to be included in the future.
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.
Current wire protocol of unbundle sends the list of all heads in the remote
repository to avoid race condition. This causes "URL too long" error on HTTP
server when the repository has many heads.
This change allows clients to send SHA1 hash of sorted head hashes instead.
Also, this introduces "unbundlehash" capability to inform them that the server
accepts hashed heads parameter.
getbundle(common, heads) -> bundle
Returns the changegroup for all ancestors of heads which are not ancestors of common. For both
sets, the heads are included in the set.
Intended to eventually supercede changegroupsubset and changegroup. Uses heads of common region
to exclude unwanted changesets instead of bases of desired region, which is more useful and
easier to implement.
Designed to be extensible with new optional arguments (which will have to be guarded by
corresponding capabilities).
known([Node]) -> [1/0]
Returns 1/0 for each node, indicating whether it's known by the server.
Needed for new discovery protocols introduced in later patches.
