From 2f99f8636abd7efc68bfa5de1591c594e9f532eb Mon Sep 17 00:00:00 2001 From: Not Zed Date: Mon, 24 Nov 2003 22:35:33 +0000 Subject: set session on print formatter for signatures to work. 2003-11-25 Not Zed * em-folder-view.c (em_folder_view_print): set session on print formatter for signatures to work. * em-message-browser.c (emmb_destroy): kill warning. * em-format-html.c (efh_output_secure): same as efhd_output_secure, output the security bar, but for printing/plain html. (efh_application_xpkcs7mime): use output_secure. (em_format_html_multipart_signed_sign): removed, output_secure does what this did. * em-format-html-display.c (smime_sign_table, smime_encrypt_table): Added a short description for the mail display. (efhd_xpkcs7mime_button): only good/bad signature at this point, if only encrypted, then display 'bad' icon. (efhd_output_secure): output the security bar/button and handle multi-level enveloping properly. (efhd_application_xpkcs7mime): just call output_secure to do the security bar. (efhd_multipart_signed): same. (efhd_signature_button): removed, no longer used. (efhd_signature_check): removed, no longer used. svn path=/trunk/; revision=23483 --- mail/em-format-html.c | 243 +++++++++++++++++++++----------------------------- 1 file changed, 102 insertions(+), 141 deletions(-) (limited to 'mail/em-format-html.c') diff --git a/mail/em-format-html.c b/mail/em-format-html.c index e1ef6be129..f3b9b46c5a 100644 --- a/mail/em-format-html.c +++ b/mail/em-format-html.c @@ -176,6 +176,7 @@ efh_finalise(GObject *o) /* FIXME: check for leaked stuff */ em_format_html_clear_pobject(efh); + camel_cipher_validity_free(efh->valid); efh_gtkhtml_destroy(efh->html, efh); @@ -556,24 +557,75 @@ efh_object_requested(GtkHTML *html, GtkHTMLEmbedded *eb, EMFormatHTML *efh) #include "em-inline-filter.h" #include +/* FIXME: This is duplicated in em-format-html-display, should be exported or in security module */ static const struct { - const char *icon; + const char *icon, *shortdesc; } smime_sign_table[4] = { - { NULL }, - { "pgp-signature-ok.png" }, - { "pgp-signature-bad.png" }, - { "pgp-signature-nokey.png" }, + { "pgp-signature-nokey.png", N_("Unsigned") }, + { "pgp-signature-ok.png", N_("Valid signature") }, + { "pgp-signature-bad.png", N_("Invalid signature") }, + { "pgp-signature-nokey.png", N_("Valid signature, cannot verify sender") }, }; static const struct { - const char *icon; + const char *icon, *shortdesc; } smime_encrypt_table[4] = { - { NULL }, - { "pgp-signature-ok.png" }, - { "pgp-signature-ok.png" }, - { "pgp-signature-ok.png" }, + { NULL, N_("Unencrypted") }, + { "pgp-signature-ok.png", N_("Encrypted, weak"),}, + { "pgp-signature-ok.png", N_("Encrypted") }, + { "pgp-signature-ok.png", N_("Encrypted, strong") }, }; +/* TODO: this could probably be virtual on em-format-html + then we only need one version of each type handler */ +static void +efh_output_secure(EMFormat *emf, CamelStream *stream, CamelMimePart *part, CamelCipherValidity *valid) +{ + CamelCipherValidity *save = ((EMFormatHTML *)emf)->valid_parent; + + /* Note: this same logic is in efhd_output_secure */ + if (((EMFormatHTML *)emf)->valid == NULL) { + ((EMFormatHTML *)emf)->valid = valid; + } else { + e_dlist_addtail(&((EMFormatHTML *)emf)->valid_parent->children, (EDListNode *)valid); + camel_cipher_validity_envelope(((EMFormatHTML *)emf)->valid_parent, valid); + } + + ((EMFormatHTML *)emf)->valid_parent = valid; + em_format_part(emf, stream, part); + ((EMFormatHTML *)emf)->valid_parent = save; + + if (((EMFormatHTML *)emf)->valid == valid + && (valid->encrypt.status != CAMEL_CIPHER_VALIDITY_ENCRYPT_NONE + || valid->sign.status != CAMEL_CIPHER_VALIDITY_SIGN_NONE)) { + char *classid; + CamelMimePart *iconpart; + + camel_stream_printf(stream, "", + valid->sign.status == CAMEL_CIPHER_VALIDITY_SIGN_GOOD?"#88bb88":"#bb8888"); + + classid = g_strdup_printf("smime:///em-format-html/%p/icon/signed", part); + camel_stream_printf(stream, "
