obsmarker: crash more helpfully when metadata fields are >255bytes (issue5681) Various mutators fail when attempting to write obsmarkers with metadata fields longer than 255 bytes, since the length of mwetadata fields is stored in u8s. This change raises a more helpful error in such circumstances. Differential Revision: https://phab.mercurial-scm.org/D865

commands: rename clone --uncompressed to --stream and document --uncompressed isn't a very good name and its description in the help documentation isn't very useful. We refer to this concept as "stream clones" in a number of places. I think it makes sense to change the user-facing argument to use the mode --stream. So this commit does that. We keep --uncompressed around for backwards compatibility. While we're here, we overhaul the help docs for streaming clones to be somewhat useful. All tests have been updated to reflect the new preferred --stream argument. A test for backwards compatibility of --uncompressed has been added. .. bc:: `hg clone --stream` should now be used instead of --uncompressed. --uncompressed is marked as deprecated and is an alias for --stream. There is no schedule for elimination of --uncompressed. Differential Revision: https://phab.mercurial-scm.org/D864

hgweb: add HTML elements to control whitespace settings for annotate Building on top of the new URL query string arguments to control whitespace settings for annotate, this commit adds HTML checkboxes reflecting the values of these arguments to the paper and gitweb themes. The actual diff settings are now exported to the templating layer. The HTML templates add these as data-* attributes so they are accessible to the DOM. A new <form> with various <input> elements is added. The <form> is initially hidden via CSS. A shared JavaScript function (which runs after the <form> has been rendered but before the annotate HTML (because annotate HTML could take a while to load and we want the form to render quickly) takes care of setting the checked state of each box from the data-* attributes. It also registers an event handler to modify the URL and refresh the page whenever the checkbox state is changed. I'm using the URLSearchParams interface to perform URL manipulation. https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams tells me this may not be supported on older web browsers. Yes, apparently the web API didn't have a standard API to parse and format query strings until recently. Hence the check for the presence of this feature in the JavaScript. If the browser doesn't support the feature, the <form> will remain hidden and behavior will like it currently is. We could polyfill this feature or implement our own query string parsing. But I'm lazy and this could be done as a follow-up if people miss it. We could certainly expand this feature to support more diff options (such as lines of context). That's why the potentially reusable code is stored in a reusable place. It is also certainly possible to add diff controls to other pages that display diffs. But since Mozillians are making noise about controlling which revisions annotate shows, I figured I'd start there. .. feature:: Control whitespace settings for annotation on hgweb /annotate URLs on hgweb now accept query string arguments to influence how whitespace changes impact results. The arguments "ignorews," "ignorewsamount," "ignorewseol," and "ignoreblanklines" now have the same meaning as their [annotate] config section counterparts. Any provided setting overrides the server default. HTML checkboxes have been added to the paper and gitweb themes to expose current whitespace settings and to easily modify the current view. Differential Revision: https://phab.mercurial-scm.org/D850

hgweb: query string arguments to control whitespace for annotate This feature should hopefully be pretty straightforward. We simply examine some query string arguments to feed into the diff options. The function to obtain the diff options has been factored into its own generic function to facilitate an upcoming change to the HTML interface and to enable diff settings to be controlled via the same query string arguments on other web commands. The test output for "ignoreblanklines" didn't change. I'm not sure why. Our test coverage for --ignore-blank-lines isn't great and I can't figure out how to make this diff setting do anything meaningful. On a very brief examination of the code, it is possible the setting doesn't work because it is operating at the line level and blank lines detection needs to examine multiple lines. But I'm not an expert in this code, so I'm not sure. Differential Revision: https://phab.mercurial-scm.org/D849
