That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (d68406e9c9b317ed461ea9b0ad4af20268ba238d) \ N -- N -- N (2264285f780c2d83de80fff8eee7da0369a577e5) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commitdiff http://git.netsurf-browser.org/netsurf.git/commit/?id=2264285f780c2d83de8... commit 2264285f780c2d83de80fff8eee7da0369a577e5 Author: Michael Drake <tlsa(a)netsurf-browser.org&gt; Commit: Michael Drake <tlsa(a)netsurf-browser.org&gt; Update to use libcss API which allows interned partial styles. diff --git a/css/select.c b/css/select.c index c9e5f7e..a4225cb 100644 --- a/css/select.c +++ b/css/select.c @@ -252,6 +252,7 @@ static void nscss_dom_user_data_handler(dom_node_operation operation, css_select_results *nscss_get_style(nscss_select_ctx *ctx, dom_node *n, uint64_t media, const css_stylesheet *inline_style) { + css_computed_style *composed; css_select_results *styles; int pseudo_element; css_error error; @@ -273,11 +274,16 @@ css_select_results *nscss_get_style(nscss_select_ctx *ctx, dom_node *n, error = css_computed_style_compose(ctx->parent_style, styles->styles[CSS_PSEUDO_ELEMENT_NONE], nscss_compute_font_size, NULL, - &(styles->styles[CSS_PSEUDO_ELEMENT_NONE])); + &composed); if (error != CSS_OK) { css_select_results_destroy(styles); return NULL; } + + /* Replace select_results style with composed style */ + css_computed_style_destroy( + styles->styles[CSS_PSEUDO_ELEMENT_NONE]); + styles->styles[CSS_PSEUDO_ELEMENT_NONE] = composed; } for (pseudo_element = CSS_PSEUDO_ELEMENT_NONE + 1; @@ -300,40 +306,20 @@ css_select_results *nscss_get_style(nscss_select_ctx *ctx, dom_node *n, styles->styles[CSS_PSEUDO_ELEMENT_NONE], styles->styles[pseudo_element], nscss_compute_font_size, NULL, - &(styles->styles[pseudo_element])); + &composed); if (error != CSS_OK) { /* TODO: perhaps this shouldn't be quite so * catastrophic? */ css_select_results_destroy(styles); return NULL; } - } - - return styles; -} - -/** - * Get an initial style - * - * \param ctx CSS selection context - * \return Pointer to partial computed style, or NULL on failure - */ -static css_computed_style *nscss_get_initial_style(nscss_select_ctx *ctx) -{ - css_computed_style *style; - css_error error; - error = css_computed_style_create(&style); - if (error != CSS_OK) - return NULL; - - error = css_computed_style_initialise(style, &selection_handler, ctx); - if (error != CSS_OK) { - css_computed_style_destroy(style); - return NULL; + /* Replace select_results style with composed style */ + css_computed_style_destroy(styles->styles[pseudo_element]); + styles->styles[pseudo_element] = composed; } - return style; + return styles; } /** @@ -346,21 +332,26 @@ static css_computed_style *nscss_get_initial_style(nscss_select_ctx *ctx) css_computed_style *nscss_get_blank_style(nscss_select_ctx *ctx, const css_computed_style *parent) { - css_computed_style *partial; + css_computed_style *partial, *composed; css_error error; - partial = nscss_get_initial_style(ctx); - if (partial == NULL) + error = css_select_default_style(ctx->ctx, + &selection_handler, ctx, &partial); + if (error != CSS_OK) { return NULL; + } + /* TODO: Do we really need to compose?
