I am unable to narrow down the issue. I have taken the sample of my daemon when the hang happened and below is log. One of the thread did try using curl_easy_perform post which ended up with OSSpinLockunlock. I was not able to gather more information from it as to what might have gone wrong. I went through the Multi-threading issue and have set CURLOPT_NOSIGNAL option to . Can any one please help me out thanks in advance.

We found that in specific cases if the connection is abruptly closed, the underlying socket is listed in a close_wait state. We continue to call the curl_multi_perform, curl_mutli_fdset etc. None of these APIs report the socket closed / connection finished. Since we have cases where the multi connection is only used once, this can pose a problem for us. I've read that if another connection was to come in, curl would see the socket as bad and attempt to close it at that time - unfortunately, this does not work for us. What I've found is that in specific situations, if SSL_write returns 0, curl does not recognize the socket as closed (or errored out) and does not report it to the application. I believe we need to change the code slightly, to check if ssl_write returns 0. If so, treat it as an error - the same as a negative return code. For OpenSSL - the ssl_write documentation is here: http://www.openssl.org/docs/ssl/SSL_write.html My proposed patch is below. Thanks!

Uploading using the standard SFTP client on Ubuntu 12.04, I'm getting around 70Kb/s (this is fine, that's just the speed of the server), but when using cURL, it's around 35Kb/s, half the speed of SFTP :/ Does anyone know of any ways I can speed up cURL, preferably without having to upgrade to a new version as I really struggled to get my version upgrading when I tried a while ago! But obviously I will if I have to to get it working. Here's the command I used for for SFTP: /usr/bin/sftp -oProtocol=2 -oIdentityFile=/path/to/key.pri -oPort=5000 -oStrictHostKeyChecking=no username&lt; at &gt;thedomain.com then just "put filename.wav" when it's connected... and with cURL: curl -v -u username: --key /path/to/key.pri --pubkey /path/to/key.pub -T /path/to/filename.wav sftp://thedomain.com:5000/folder/TEST/filename.wav --insecure This is the cURL version info: curl 7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 libssh2/1.2.8 librtmp/2.3 Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3 pop3s rtmp rtsp scp sftp smtp smtps telnet tftp Features: GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP I assume it's not like this for everyone? ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html </pre> Ben Thomas 2013-05-22T12:06:23 http://comments.gmane.org/gmane.comp.web.curl.library/39473 <pre>In xmlrpc-c, when timeout occurred, there are no messages in the queue, so, when it calls curl_multi_info_read to get privateCurlMsgP, curl_multi_info_read will return NULL. In this situation, xmlrpc fails to get resources and the memory won't be freed. In normal situation, curl_multi_info_read will return te messages. Then, calls curl_easy_getinfo to retrieve information from a performed transfer. Finally xmlrpc-c calls the function curlTransaction_finish of its own to release the resources. However, if timeout occurs, curl_multi_info_read return &amp;easy-&gt;msg-&gt;extmsg which is NULL. Is there a function in curl like curl_multi_info_read which returns the easy-&gt;easy_handle directly?

I'm currently trying to make a PHP script with cURL that needs to store cookies, I tried to use the "normal" cookie file with CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE but I am using parallel connections and need the cookie immediatly after the request was made. I search a lot and noticed there isn't a standard way to store cookies in variables, so I decided to try to modify cURL source to implement this. What I had in mind was to check how cookies where written to files with CURLOPT_COOKIEJAR but instead of writing the cookies to files, returning them so they could be stored in variables, I would like to do something like this in PHP: curl_setopt($handle, CURLOPT_COOKIEVAR, $cookie); Where CURLOPT_COOKIEVAR would be the name of the option to store cookies in variables and $cookie would store the cookie in a string. So, my question is, any idea of where in cURL's source CURLOPT_COOKIEJAR is implemented? Thanks in advance. ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html </pre> Rodrigo 2013-05-17T19:51:30 http://comments.gmane.org/gmane.comp.web.curl.library/39446 <pre>Hello cURL hackers, I found a bug which cURL sends cookies to the path not to aim at. For example: - cURL sends a request to http://example.fake/hoge/ - server returns cookie which with path=/hoge; the point is there is NOT the '/' end of path string. - cURL sends a request to http://example.fake/hogege/ with the cookie. Because Curl_cookie_getlist() compares path using strncmp(). I think cURL should send without the cookie, this case. An attached patch fixs this problem and test case.

The binary distribution works fine, but I need a C/C++ callable interface to eliminate needless spawning of CURL.EXE.

I see from the build_vms.com script that one could use NOSSL, however there is no option to turn off GNUTLS (or any other possible GNU libraries) I checked the archive and the last traffic circa Mar 2013 implies outstanding problems with the VMS build had been addressed.

Everything is working quite well with libcurl, but I have a problem using SSL secured requests in Windows. I am cross compiling libcurl on Linux using MXE, but I get SSL errors when setting the path to the cacert.pem from the library. This is what I have tried: I am setting the cacert path using curl_easy_setopt(curl_handle, CURLOPT_SSLCERT, common-&gt;cert_path); where common-&gt;cert_path is char[2048] (not a pointer, just for testing) and is C:/Program Files (x86)/pd/extra/purest_json/cacert.pem cacert.pem is the download from http://curl.haxx.se/docs/caextract.html, and I have set read/write access to everyone, I have already tried replacing slashes with backslashes. Here are the configure scripts from MXE that I have tried and the error codes: gnutls: ------- ./configure \ --host='$(TARGET)' \ --build="`config.guess`" \ --disable-shared \ --prefix='$(PREFIX)/$(TARGET)' \ --with-gnutls \ --without-ssl \ --with-libidn \ --enable-sspi \ --enable-ipv6 \ --with-libssh2 error code: CURLE_SSL_CACERT_BADFILE (77) openssl: -------- ./configure \ --host='$(TARGET)' \ --build="`config.guess`" \ --disable-shared \ --prefix='$(PREFIX)/$(TARGET)' \ --without-gnutls \ --with-ssl \ --with-libidn \ --enable-sspi \ --enable-ipv6 \ --with-libssh2 error code: CURLE_SSL_CERTPROBLEM (58) My C code for using libcurl is at https://github.com/residuum/PuRestJson/blob/master/ctw.c Thanks for you help, Thomas </pre> Thomas Mayer 2013-05-13T20:13:25 http://comments.gmane.org/gmane.comp.web.curl.library/39417 <pre>Hi all, I've just switched the web site to now update its contents automatically from this git repository: https://github.com/bagder/curl-www Please point out any problems you encounter as I'm sure there are some flaws left due to this transition. </pre> Daniel Stenberg 2013-05-13T17:44:39 http://comments.gmane.org/gmane.comp.web.curl.library/39415 <pre>We've been getting a problem with our unit tests where FTP uploads using curl_multi were stalling. The test in question starts off three uploads and three downloads to the same server in parallel. Unless we're somehow missing an error condition somewhere, it looks like all the uploads hang. I seem to have tracked this down to commit 57aeabcc1a20ff8ed1d725ef0309d0d8f64194d8. Taking the latest code (7ed25ccf0d1e5b8c7fd3bd90f0375a06011cd394 ), then reversing commit 57aeabcc1a20ff8ed1d725ef0309d0d8f64194d8, seems to be enough to fix the stall for us. I'm not sure if the problem is the libcurl code itself, or some side-effect of the change, maybe taking away some other behaviour that we're relying on. I don't have a plain C test yet, but I'll attempt to make one if I can. I thought I'd give you a heads-up in the meantime, just in case it's a problem that someone else can verify in the meantime.

When just CURLOPT_POSTFIELDS and CURLOPT_POSTFIELDSIZE are set I can see correct Content-Length header in the outgoing request. Problem starts when I also set CURLOPT_COOKIE, then I can see valid Cookie header in the request but Content-Length is suddenly missing. Changing the order of actions (first cookie then post) doesn't work either (I thought maybe I was overwriting header with CUROPT_COOKIE) What is happening?

We used the source archive from here: http://curl.haxx.se/download.html. I have some questions how to use libcurl for IMAP because it seems so for us that the new IMAP functions are only working in the command line curl and not with the libcurl functions. But as I understood the published changelog and the updated documentation for setopt (http://curl.haxx.se/libcurl/c/curl_easy_setopt.html) they should also work for the libcurl functions, or am I mistaken? For initializing I use the following (and the corresponding functions for cleaning up): curl_global_init(CURL_GLOBAL_ALL); curl = curl_easy_init(); But I think curl_global_init is not meant to activate the new IMAP functions, right? curl command line version: curl 7.30.0 (mipsel-unknown-linux-uclibc) libcurl/7.30.0 OpenSSL/1.0.1e Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp Features: Largefile NTLM NTLM_WB SSL TLS-SRP libcurl version result from "curl_version()" &lt;libcurl/7.30.0 OpenSSL/1.0.1e&gt; Some examples: For all of these: I exchanged the real user and password with just “user:password”, user is in this case normally the complete email address with %40 instead of the &lt; at &gt; sign. The command line curl version works always pretty fine, but with the same url the libcurl function do not deliver the same result (or no result). There are two mails in this INBOX. 1a) IMAP test 1, command line: curl -v -o imap.txt 'imap://user:password&lt; at &gt;imap.1und1.de' - delivers the folder list including the folder “INBOX” * LIST (\HasNoChildren) "/" Drafts * LIST (\HasNoChildren) "/" INBOX * LIST (\HasNoChildren) "/" Sent * LIST (\HasNoChildren) "/" Spam * LIST (\HasNoChildren) "/" Trash 1b) IMAP test 1, libcurl functions: CURLOPT_URL, “imap://user:password&lt; at &gt;imap.1und1.de” CURLOPT_HEADER, 1 CURLOPT_WRITEFUNCTION, WriteMemoryCallback CURLOPT_WRITEDATA, (void *)&amp;data CURLOPT_HEADERFUNCTION, WriteMemoryCallback CURLOPT_WRITEHEADER, (void *)&amp;header - delivers the multipart message from the body of the first mail as data - delivers the IMAP protocol handshake and messages as header - It should normally list the folders Even if I would use the mail content from here, the email header would be missing (although I used CURLOPT_HEADER, 1) and I do not know from, to, subject and date. 2a) IMAP test 2, command line: curl -v -o imap.txt 'imap://user:password&lt; at &gt;imap.1und1.de/INBOX' - delivers: * LIST (\HasNoChildren) "/" INBOX 2b) IMAP test 2, libcurl functions: CURLOPT_URL, “imap://user:password&lt; at &gt;imap.1und1.de/INBOX” CURLOPT_HEADER, 1 CURLOPT_WRITEFUNCTION, WriteMemoryCallback CURLOPT_WRITEDATA, (void *)&amp;data CURLOPT_HEADERFUNCTION, WriteMemoryCallback CURLOPT_WRITEHEADER, (void *)&amp;header - delivers the multipart message from the body of the first mail as data - delivers the IMAP protocol handshake and messages as header - It should normally list the folders Even if I would use the mail content from here, the email header would be missing (although I used CURLOPT_HEADER, 1) and I do not know from, to, subject and date. 3a) IMAP test 3, command line: curl -v -o imap.txt 'imap://user:password&lt; at &gt;imap.1und1.de/INBOX/;uid=1' - delivers the complete email header (Return-Path, ...

Questions regarding IMAP: Why does IMAP work with the command line curl but not with the libcurl functions? How would I get the mail header (it should be included when using "CURLOPT_HEADER, 1" or why not?)? Is there any easy possibility to get the total number of messages? Ok, I could parse the header to find the following which is included there, but is there a IMAP url with which I get this as result in data, like pop3 example 4a?: * 2 EXISTS * 0 RECENT Thanks, Regards, xyzzyx ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html</pre> xyzzyx 2013-05-12T15:37:09 http://comments.gmane.org/gmane.comp.web.curl.library/39402 <pre>Hello, I think there is a memory leak in the curl code.

Background: Given an https://example.com/something URL, where example.com points to multiple IP addresses I want to be able to choose which IP address to connect to (for various reasons). If this was HTTP it would be easy: just use the IP in the URL. However if I do that with HTTPS then certificate verification fails as expected. I could turn off SSL_VERIFYHOST and do the verification myself, but I'd have to duplicate all of curl's hostname verification logic and I'd rather not do that... My current workaround is: * keep the domain name in the URL: https://example.com/something * override the IP address either by: * using CURLOPT_RESOLVE example.com:443:127.0.1.1 * using CURLOPT_OPENSOCKETFUNCTION and changing the data in the *address pointer to point to my IP (127.0.1.1 in this example) * SSL verification succeeds now (its using the domain name from the URL) However this stops working as soon as I try to connect to more than one IP address with same hostname,with the multi interface: * 1st call: OPENSOCKETFUNCTION callback changes IP for example.com to 127.0.1.1, this works * next URL https://example.com, but I want to use 127.0.1.2 now * curl will reuse the connection from the first IP (127.0.1.1) I've given it, and won't call my opensocket callback anymore I could use CURLOPT_FRESHCONNECT to force a new connection, but then I won't be able to reuse my connection with 127.0.1.1 ever. Would it help if I return the cached socket from OPENSOCKETFUNCTION callback, and CURL_SOCKOPT_ALREADY_CONNECTED from CURLOPT_SOCKOPT_FUNCTION?
