From: Nicolas Morey-Chaisemartin <NMoreyChaisemartin@xxxxxxxx> When trying to send a patch using 'imap-send' with 'curl' and the following configuration: [imap] folder = "[Gmail]/Drafts" host = imaps://imap.gmail.com port = 993 sslverify = false results in the following error, curl_easy_perform() failed: URL using bad/illegal format or missing URL This is a consequence of not URI-encoding the folder portion of the URL which contains characters such as '[' which are not allowed in a URI. According to RFC3986, these characters should be URI-encoded. So, URI-encode the folder before adding it to the URI to ensure it doesn't contain characters that aren't allowed in a URI.

You're welcome. It was easier than waiting for this patch to be updated so it could get into 'pu' ;-) imap-send.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/imap-send.c b/imap-send.c index 54e6a80fd..36c7c1b4f 100644 --- a/imap-send.c +++ b/imap-send.c @@ -1412,6 +1412,7 @@ static CURL *setup_curl(struct imap_server_conf *srvc, struct credential *cred) { CURL *curl; struct strbuf path = STRBUF_INIT; + char *uri_encoded_folder; if (curl_global_init(CURL_GLOBAL_ALL) != CURLE_OK) die("curl_global_init failed"); @@ -1429,7 +1430,12 @@ static CURL *setup_curl(struct imap_server_conf *srvc, struct credential *cred) strbuf_addstr(&path, server.host); if (!path.len || path.buf[path.len - 1] != '/') strbuf_addch(&path, '/'); - strbuf_addstr(&path, server.folder); + + uri_encoded_folder = curl_easy_escape(curl, server.folder, 0); + if (!uri_encoded_folder) + die("failed to encode server folder"); + strbuf_addstr(&path, uri_encoded_folder); + curl_free(uri_encoded_folder); curl_easy_setopt(curl, CURLOPT_URL, path.buf); strbuf_release(&path); -- 2.15.1.620.gb9897f467
