From 00b5623d1a21d886b564d031e30749e5d02e4ae6 Mon Sep 17 00:00:00 2001 From: Thomas Jost Date: Fri, 20 Jan 2012 10:39:24 +0100 Subject: Add compatibility with gmime 2.6 There are lots of API changes in gmime 2.6 crypto handling. By adding preprocessor directives, it is however possible to add gmime 2.6 compatibility while preserving compatibility with gmime 2.4 too. This is mostly based on id:"8762i8hrb9.fsf@bookbinder.fernseed.info". This was tested against both gmime 2.6.4 and 2.4.31. With gmime 2.4.31, the crypto tests all work fine (as expected). With gmime 2.6.4, one crypto test is currently broken (signature verification with signer key unavailable), most likely because of a bug in gmime which will hopefully be fixed in a future version. --- notmuch-show.c | 95 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 95 insertions(+) (limited to 'notmuch-show.c') diff --git a/notmuch-show.c b/notmuch-show.c index c674e25..43ee211 100644 --- a/notmuch-show.c +++ b/notmuch-show.c @@ -76,7 +76,11 @@ static void format_part_encstatus_json (int status); static void +#ifdef GMIME_ATLEAST_26 +format_part_sigstatus_json (GMimeSignatureList* siglist); +#else format_part_sigstatus_json (const GMimeSignatureValidity* validity); +#endif static void format_part_content_json (GMimeObject *part); @@ -486,6 +490,21 @@ show_text_part_content (GMimeObject *part, GMimeStream *stream_out) g_object_unref(stream_filter); } +#ifdef GMIME_ATLEAST_26 +static const char* +signature_status_to_string (GMimeSignatureStatus x) +{ + switch (x) { + case GMIME_SIGNATURE_STATUS_GOOD: + return "good"; + case GMIME_SIGNATURE_STATUS_BAD: + return "bad"; + case GMIME_SIGNATURE_STATUS_ERROR: + return "error"; + } + return "unknown"; +} +#else static const char* signer_status_to_string (GMimeSignerStatus x) { @@ -501,6 +520,7 @@ signer_status_to_string (GMimeSignerStatus x) } return "unknown"; } +#endif static void format_part_start_text (GMimeObject *part, int *part_count) @@ -592,6 +612,73 @@ format_part_encstatus_json (int status) printf ("}]"); } +#ifdef GMIME_ATLEAST_26 +static void +format_part_sigstatus_json (GMimeSignatureList *siglist) +{ + printf (", \"sigstatus\": ["); + + if (!siglist) { + printf ("]"); + return; + } + + void *ctx_quote = talloc_new (NULL); + int i; + for (i = 0; i < g_mime_signature_list_length (siglist); i++) { + GMimeSignature *signature = g_mime_signature_list_get_signature (siglist, i); + + if (i > 0) + printf (", "); + + printf ("{"); + + /* status */ + GMimeSignatureStatus status = g_mime_signature_get_status (signature); + printf ("\"status\": %s", + json_quote_str (ctx_quote, + signature_status_to_string (status))); + + GMimeCertificate *certificate = g_mime_signature_get_certificate (signature); + if (status == GMIME_SIGNATURE_STATUS_GOOD) { + if (certificate) + printf (", \"fingerprint\": %s", json_quote_str (ctx_quote, g_mime_certificate_get_fingerprint (certificate))); + /* these dates are seconds since the epoch; should we + * provide a more human-readable format string? */ + time_t created = g_mime_signature_get_created (signature); + if (created != -1) + printf (", \"created\": %d", (int) created); + time_t expires = g_mime_signature_get_expires (signature); + if (expires > 0) + printf (", \"expires\": %d", (int) expires); + /* output user id only if validity is FULL or ULTIMATE. */ + /* note that gmime is using the term "trust" here, which + * is WRONG.
