But, when I run the same piece of code(sftp_write) separately it works fine for me. One thing I observed is that my project uses one socket for communication whereas libssh2 uses another for establishing SSH session. This issue is applicable only on Solaris and it works fine for me on Linux & Windows. So, does libssh2 has any issue when establishing a SSH session if one socket session is already ON? (Especially on Solaris) Initially I found this issue using libcurl which internally uses libssh2. Here is the sample libssh2 code which I have used in my project: ********************sample code**************** /* * The application code is responsible for creating the socket * and establishing the connection */ sock = socket(AF_INET, SOCK_STREAM, 0); sin.sin_family = AF_INET; sin.sin_port = htons(22); sin.sin_addr.s_addr = hostaddr; if (connect(sock, (struct sockaddr*)(&sin), sizeof(struct sockaddr_in)) != 0) { fprintf(stderr, "failed to connect!\n"); exit(0); } /* Create a session instance */ session = libssh2_session_init(); if(!session) exit(0); /* Since we have set non-blocking, tell libssh2 we are blocking */ libssh2_session_set_blocking(session, 1); /* ... start it up. This will trade welcome banners, exchange keys, * and setup crypto, compression, and MAC layers */ rc = libssh2_session_startup(session, sock); if(rc) { cout<<"errno = "< libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Tue Feb 1 13:54:54 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p11CrZ0I004120; Tue, 1 Feb 2011 13:54:51 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p11CrYUb004087 for ; Tue, 1 Feb 2011 13:53:34 +0100 Received: (qmail 1296 invoked from network); 1 Feb 2011 12:53:22 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 1 Feb 2011 12:53:22 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 0.12 Precedence: bulk Cc: libssh2-devel@cool.haxx.se Auto-Submitted: auto-generated X-Mailer: Trac 0.12, by Edgewall Software X-Trac-Project: libssh2 Date: Tue, 01 Feb 2011 12:53:22 -0000 X-URL: http://trac.libssh2.org/ Subject: [libssh2] #209: Failure in build of the example programs (1.2.7 static on MinGW) X-Trac-Ticket-URL: http://trac.libssh2.org/ticket/209 Message-ID: <042.4cd3759d93cddb77416601aabd251640@libssh2.stuge.se> X-Trac-Ticket-ID: 209 X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se #209: Failure in build of the example programs (1.2.7 static on MinGW) --------------------------+------------------------------------------------- Reporter: arithy | Owner: Type: build error | Status: new Priority: normal | Milestone: Component: examples | Version: 1.2.7 Keywords: | Blocks: Blocked By: | --------------------------+------------------------------------------------- I failed to build 1.2.7 on MinGW using the static library option.

In libssh2_tarnsport_read (src/transport.c) on line 454 total_num is computed as p->total_num = p->packet_length - 1 + (encrypted ? session->remote.mac->mac_len : 0); In this case if packet_length is greater than (2 pow 30) we get a total_num value that is -ve. In this case libssh2 gets stuck in a infinite do {} while loop inside libssh2_transport_read. I understand from definition of LIBSSH2_PACKET_MAXPAYLOAD and the comment right after the total_num calculation that maximum uncompressed payload should never be greater than 40000, so its likely that what we are getting from the other side here has a bogus packet length (in the particular case it was 3359664964). However with the type/size mismatch we bypass the check on line 466 in src/trasport.c i.e. if (p->total_num > LIBSSH2_PACKET_MAXPAYLOAD) { return LIBSSH2_ERROR_OUT_OF_BOUNDARY; } Subsequently we get stuck in the infinite do {}while loop. Suggested solution, define both packet_length and total_num to be of type uint32_t. -- Ticket URL: libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Tue Feb 15 14:24:08 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p1FDNkpj028472; Tue, 15 Feb 2011 14:24:03 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p1FDNiXM028437 for ; Tue, 15 Feb 2011 14:23:44 +0100 Received: (qmail 16643 invoked from network); 15 Feb 2011 13:23:42 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 15 Feb 2011 13:23:42 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 0.12 Precedence: bulk Cc: libssh2-devel@cool.haxx.se Auto-Submitted: auto-generated X-Mailer: Trac 0.12, by Edgewall Software X-Trac-Project: libssh2 Date: Tue, 15 Feb 2011 13:23:42 -0000 X-URL: http://trac.libssh2.org/ Subject: Re: [libssh2] #210: make check and install fail on Solaris (OpenIndiana x86) X-Trac-Ticket-URL: http://trac.libssh2.org/ticket/210#comment:2 Message-ID: <056.c9848a33353e1e3bc4638de5b4607b99@libssh2.stuge.se> References: <041.9be3250759a64acfab2d0aafd3ff2a89@libssh2.stuge.se> X-Trac-Ticket-ID: 210 In-Reply-To: <041.9be3250759a64acfab2d0aafd3ff2a89@libssh2.stuge.se> X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se #210: make check and install fail on Solaris (OpenIndiana x86) --------------------------+------------------------------------------------- Reporter: dzejk | Owner: Type: build error | Status: new Priority: normal | Milestone: 1.2.7 Component: tests | Version: 1.2.7 Resolution: | Keywords: Blocks: | Blocked By: --------------------------+------------------------------------------------- Comment (by dzejk): Please find attached the requested files.

Until now this has worked perfectly every time for me. No customisations have been made to the library. It performs several SFTP fetches to retrieve zipped data, processes them and stores the results locally. It then transmits those results back using SFTP to multiple locations. The error appears on both w2k8 64bit and xp/sp3 32bit. Recompiled zlib to 1.2.5 and openssl to 0.9.8r just in case, no effect. Tested against 3 different servers - CompleteFTP and freesshd local to the machine and linux openssh on a virtual machine; all 3 exhibit the same problem at approximately the same point. None of the servers report anything out of the ordinary in their logs. The exact same code works correctly if I limit the threading to only one transfer at once, even though though each transfer occurs in it's own thread with the session created and accessed from only that one thread. I hope to recreate this using a much-simplified multi-threaded C program and attach the program to this ticket, but if there's anything I can provide before then, please let me know. -- Ticket URL: libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Tue Feb 15 19:35:52 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p1FIZb8j012353; Tue, 15 Feb 2011 19:35:50 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.3/8.14.3/Debian-9.1) with ESMTP id p1FIZaJ3012340 for ; Tue, 15 Feb 2011 19:35:36 +0100 Received: (qmail 22831 invoked from network); 15 Feb 2011 18:35:33 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 15 Feb 2011 18:35:33 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 0.12 Precedence: bulk Cc: libssh2-devel@cool.haxx.se Auto-Submitted: auto-generated X-Mailer: Trac 0.12, by Edgewall Software X-Trac-Project: libssh2 Date: Tue, 15 Feb 2011 18:35:33 -0000 X-URL: http://trac.libssh2.org/ Subject: Re: [libssh2] #212: Win32 access violation reading beyond module's executable address space X-Trac-Ticket-URL: http://trac.libssh2.org/ticket/212#comment:1 Message-ID: <100.4f66b544b1ba238b6bf90ba73eca6a82@libssh2.stuge.se> References: <085.75fcd2f2729a1c4fe91d486bf364da18@libssh2.stuge.se> X-Trac-Ticket-ID: 212 In-Reply-To: <085.75fcd2f2729a1c4fe91d486bf364da18@libssh2.stuge.se> X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se #212: Win32 access violation reading beyond module's executable address space ----------------------------------------------------------------+----------- Reporter: me.yahoo.com/a/zb4rfgwuv_ft.mggqltssk.ndw--#37f15 | Owner: bagder Type: defect | Status: assigned Priority: normal | Milestone: 1.2.8 Component: SFTP | Version: 1.2.7 Resolution: | Keywords: Blocks: | Blocked By: ----------------------------------------------------------------+----------- Changes (by bagder): * owner: => bagder * status: new => assigned Comment: Do you have the openssl mutex callbacks set?

(Though it could also be a problem in libssh2 that gives libgcrypt bogus data and causes it to run off and do something silly.) Is there a way to find out which case this maybe. I can possibly dissassmble the code and tell you the values of the arguements (which got optimized out to be passed in registers) passed to the gcrypt function (although I guess those could have been smashed as well, libgcrypt is relying on a ton of handwritten assembly code).

No, it is not possible. libssh2 implements SFTP version 3 and it doesn't provide that information. If libssh2 would implement a later SFTP version and the server you're communicating with also does, then it would be possible... I believe for example OpenSSH also only implement SFTP version 3. See http://www.greenend.org.uk/rjk/2007/sftpversions.html for a great overview of SFTP differences. -- / daniel.haxx.se _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Sat Feb 19 22:45:26 2011 Return-Path: Received: from giant.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1JLj16L028578;

Using the API in blocking mode, right?

My hunch is that what you're seeing is simply that while receiving a bl= ock of data over a slow network link, then libssh2 will keep returning EAGA= IN internally and the blocking API will sit there waiting for a full packet= to arrive before it returns anyway.

If you really want to avoid that the function blocks for a certain period o= f time at some invokes, I think you should consider the non-blocking approa= ch.

Or do you think it can be something else?

Code is quite long but functions connection() and makeconnection() are just lightly modified code of connection example from libssh2 site (http://libssh2.org/examples/ssh2.html) so the interesting par= t is only function mainloop().

sorry for that.



Thank you for quick response. Unfortunately this isn't the solution for= my problem because channel is set for nonblocking few lines before code i = pasted using

Okay, so what version are you using on what operating system?

i'm using
system: Debian 2.6.32-28
libssh2= version 1.2.7
and all of this is on quite old and slow machine:
cpu = 800 mhz 64 KB cache
memory 256 MB
but still it isn't a piece of junk i remember i've played for example q= uake 2 on similar machine=A0 and there were no problems at all and i don't think that sending encrypted package of 4 KB size could be more demanding than that.
i have made some test on faster machine (cpu 2400 m= hz 1024 KB chache) and everything goes fine there.

Have you tried to repeat the problem with a recent snapshot/git version?
yes, nothing changed.
=

also there i use function libssh2_channel_handle_extended_data2(channel, LI= BSSH2_CHANNEL_EXTENDED_DATA_MERGE); but i don't suppose that it have in= fluence on my problem.

Can you help us help you and provide a full example that repeats this probl= em?

i post here mostly simplified working code wi= th this error(compile with -lssh2 -lncurses).

Look at example/direct_tcpip.c for the method which you *must* use when you want to handle both a libssh2 channel and some other communications channel. (stdin in your case) I bet that if you press enter in this ssh client then you will get some more "missing" data displayed on your screen. //Peter _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Fri Feb 25 13:30:34 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1PCU6ej032318; Fri, 25 Feb 2011 13:30:30 +0100 Received: from mail.icesoft.ro (mail.icesoft.ro [89.42.24.215]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1PCU40x032053 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT) for ; Fri, 25 Feb 2011 13:30:04 +0100 Received: from unknown-00-1b-77-6f-f5-f5.lan (unknown [89.122.225.202]) by mail.icesoft.ro (Postfix) with ESMTP id 3FCA124401A for ; Fri, 25 Feb 2011 14:30:03 +0200 (EET) From: Serghei Amelian To: libssh2-devel@cool.haxx.se Subject: sftp - errors Date: Fri, 25 Feb 2011 14:30:16 +0200 User-Agent: KMail/1.9.10 (enterprise35 0.20100827.1168748) MIME-Version: 1.0 Content-Disposition: inline Message-Id: <201102251430.16298.serghei.amelian@gmail.com> X-Greylist: Sender passed SPF test, not delayed by milter-greylist-4.3.8 (giant.haxx.se [127.0.0.1]); Fri, 25 Feb 2011 13:30:34 +0100 (CET) X-Greylist: Default is to whitelist mail, not delayed by milter-greylist-4.3.8 (giant.haxx.se [80.67.6.50]); Fri, 25 Feb 2011 13:30:04 +0100 (CET) X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Precedence: list Reply-To: libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se Hello list, I developing a sftp kioslave for trinity desktop environment and I want to give to users useful message when, for example, a file cannot be opened for some reason (file doesn't exists, access denied, etc). libssh2_sftp_open() returns LIBSSH2_ERROR_SFTP_PROTOCOL in these cases, which are completely meaningless for an user.

Did you look at the secsh-filexfer protocol to find out if the protocol allows a message from the server or if structured errors are returned? Did you look at libssh2 headers or documentation for any API that may offer you more information about errors?

However on closer inspection, this read is coming as a result of calling libssh_channel_free after the error. To illustrate, here is the backtrace. #0 0x0000000000a5b8db in _libssh2_transport_read (session=0x7f42e368ff80) at transport.c:536 #1 0x0000000000a531e1 in _libssh2_channel_close (channel=0x7f42e3606a20) at channel.c:2257 #2 0x0000000000a5339b in _libssh2_channel_free (channel=0x7f42e3606a20) at channel.c:2386 #3 0x0000000000a533d8 in libssh2_channel_free (channel=0x7f42e3606a20) at channel.c:2461 #4 0x00000000005b917a in SSHSession::clearChannel (this=0x7f42e29e11a0) at sessions/ssh-session.cc:61 #5 0x00000000005b8247 in SSHSession::disconnect (this=0x7f42e29e11a0) at sessions/ssh-session.cc:45 #6 0x00000000005beaf0 in QuerySession::errorOccurred (this=0x7f42e29e11a0, sessErr=@0x1058640) at sessions/query-session.cc:243 #7 0x00000000005bfc41 in QuerySession::doRead (this=0x7f42e29e11a0) at sessions/query-session.cc:330 #8 0x00000000005b68f2 in SSHSession::doRead (this=0x7f42e29e11a0) at sessions/ssh-session.cc:331 #9 0x00000000005c2091 in QuerySession::fdReadReady (this=0x7f42e29e11a0) at sessions/query-session.cc:150 #10 0x00000000005b81ef in SSHSession::fdReadReady (this=0x7f42e29e11a0) at sessions/ssh-session.cc:237 #11 0x00000000009f6481 in Scheduler::run () #12 0x000000000065f4b4 in main (argc=8, argv=0x7fffd9d24a18) at main.cc:389 Current language: auto; currently c i.e. the same bogus packet length value is causing libssh2 to get stuck in the same way as described in comment #0. Suggested solution - if returning an error (rc < 0) other than EAGAIN, set session.packet.total_num = 0. An easy way to do this is to add a level on indirection to _libssh2_transport_read for example by making _libssh2_trasport_read be defined as int _libssh2_tranport_read(LIBSSH2_SESSION * session){ int rc = libssh2_transport_read(session); if (rc < 0 && rc != LIBSSH2_ERROR_EAGAIN) session.packet.total_num = 0; return rc; } where libssh2_trasport_read is the same as _libssh2_trasport_read is current code. For consistency of naming I could add a similar indirection in _libssh2_transport_send. But since there is no point adding a extra function call there we could define _libssh2_transport_send with a macro (that just calls libssh2_transport_send). Alternatively if it is important to not add the extra function call cost to libssh2_transport_read. I can reset the session.packet.total_num value inside the function in case of error. However this is more error prone. Please reply and I can roll you a patch for this. -- Ticket URL: libssh2 C library for writing portable SSH2 clients _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Sat Feb 26 05:24:43 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1Q4OM4s030118; Sat, 26 Feb 2011 05:24:40 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1Q4OKMr030076 for ; Sat, 26 Feb 2011 05:24:20 +0100 Received: (qmail 6192 invoked from network); 26 Feb 2011 04:24:20 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 26 Feb 2011 04:24:20 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 0.12 Precedence: bulk Cc: libssh2-devel@cool.haxx.se Auto-Submitted: auto-generated X-Mailer: Trac 0.12, by Edgewall Software X-Trac-Project: libssh2 Date: Sat, 26 Feb 2011 04:24:20 -0000 X-URL: http://trac.libssh2.org/ Subject: Re: [libssh2] #211: size mismatch between struct transportpacket fields causes libssh2 to get stuck X-Trac-Ticket-URL: http://trac.libssh2.org/ticket/211#comment:3 Message-ID: <123.97ad0fc4affbf8cecadc76e01e9398cd@libssh2.stuge.se> References: <108.62cba77b47352402c1cd0687daecf8b2@libssh2.stuge.se> X-Trac-Ticket-ID: 211 In-Reply-To: <108.62cba77b47352402c1cd0687daecf8b2@libssh2.stuge.se> X-Greylist: Sender passed SPF test, not delayed by milter-greylist-4.3.8 (giant.haxx.se [127.0.0.1]); Sat, 26 Feb 2011 05:24:43 +0100 (CET) X-Greylist: Default is to whitelist mail, not delayed by milter-greylist-4.3.8 (giant.haxx.se [80.67.6.50]); Sat, 26 Feb 2011 05:24:20 +0100 (CET) X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id p1Q4OKMr030076 X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="utf-8" Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id p1Q4OM4s030118 #211: size mismatch between struct transportpacket fields causes libssh2 to get stuck ---------------------------------------------------------------------------------------+ Reporter: www.google.com/accounts/o8/id?id=aitoawlhggg_yplkl7grwwpbbum-omtqud4rmna | Owner: Peter Stuge Type: defect | Status: closed Priority: normal | Milestone: 1.2.8 Component: protocol | Version: 1.2.7 Resolution: fixed | Keywords: Blocks: | Blocked By: ---------------------------------------------------------------------------------------+ Changes (by Peter Stuge ): * owner: => Peter Stuge * status: reopened => closed * resolution: => fixed Comment: In [516fa7fdd9b55def83c124f223889c70b9e021ab/libssh2]: {{{ #!CommitTicketReference repository="libssh2" revision="516fa7fdd9b55def83c124f223889c70b9e021ab" Don't save allocated packet size until it has actually been allocated The allocated packet size is internal state which needs to match reality in order to avoid problems.

Commit messages can contain commands that automatically add a comment to a ticket, and also optionally close it. --8<-- commit_updater.py docs Update tickets based on commit messages. This component hooks into changeset notifications and searches commit messages for text in the form of: {{{ command #1 command #1, #2 command #1 & #2 command #1 and #2 }}} Instead of the short-hand syntax "#1", "ticket:1" can be used as well, e.g.: {{{ command ticket:1 command ticket:1, ticket:2 command ticket:1 & ticket:2 command ticket:1 and ticket:2 }}} In addition, the ':' character can be omitted and issue or bug can be used instead of ticket. You can have more than one command in a message. The following commands are supported. There is more than one spelling for each command, to make this as user-friendly as possible. close, closed, closes, fix, fixed, fixes:: The specified tickets are closed, and the commit message is added to them as a comment. references, refs, addresses, re, see:: The specified tickets are left in their current status, and the commit message is added to them as a comment. A fairly complicated example of what you can do is with a commit message of: Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12. This will close #10 and #12, and add a note to #12. -->8-- I forgot a setting that makes TracGit map email addresses to registered user names, which is why it put my full name and email instead of my username as owner. I've fixed the setting now, so next time someone uses this it will work, as long as your email address configured in Trac is the same as the email address configured in Git when you create the commit. //Peter _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Mon Feb 28 23:34:38 2011 Return-Path: Received: from giant.haxx.se (localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1SMYGav011458; Mon, 28 Feb 2011 23:34:34 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-2) with ESMTP id p1SMYFlh011441 for ; Mon, 28 Feb 2011 23:34:15 +0100 Received: (qmail 371 invoked from network); 28 Feb 2011 22:34:17 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 28 Feb 2011 22:34:17 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 0.12 Precedence: bulk Cc: libssh2-devel@cool.haxx.se Auto-Submitted: auto-generated X-Mailer: Trac 0.12, by Edgewall Software X-Trac-Project: libssh2 Date: Mon, 28 Feb 2011 22:34:17 -0000 X-URL: http://trac.libssh2.org/ Subject: Re: [libssh2] #211: size mismatch between struct transportpacket fields causes libssh2 to get stuck X-Trac-Ticket-URL: http://trac.libssh2.org/ticket/211#comment:4 Message-ID: <123.c13ea96b4489941154298a1e72fd621a@libssh2.stuge.se> References: <108.62cba77b47352402c1cd0687daecf8b2@libssh2.stuge.se> X-Trac-Ticket-ID: 211 In-Reply-To: <108.62cba77b47352402c1cd0687daecf8b2@libssh2.stuge.se> X-Greylist: Sender passed SPF test, not delayed by milter-greylist-4.3.8 (giant.haxx.se [127.0.0.1]); Mon, 28 Feb 2011 23:34:38 +0100 (CET) X-Greylist: Default is to whitelist mail, not delayed by milter-greylist-4.3.8 (giant.haxx.se [80.67.6.50]); Mon, 28 Feb 2011 23:34:15 +0100 (CET) X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id p1SMYFlh011441 X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.13 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="utf-8" Sender: libssh2-devel-bounces@cool.haxx.se Errors-To: libssh2-devel-bounces@cool.haxx.se Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id p1SMYGav011458 #211: size mismatch between struct transportpacket fields causes libssh2 to get stuck ---------------------------------------------------------------------------------------+ Reporter: www.google.com/accounts/o8/id?id=aitoawlhggg_yplkl7grwwpbbum-omtqud4rmna | Owner: Peter Stuge Type: defect | Status: closed Priority: normal | Milestone: 1.2.8 Component: protocol | Version: 1.2.7 Resolution: fixed | Keywords: Blocks: | Blocked By: ---------------------------------------------------------------------------------------+ Comment (by www.google.com/accounts/o8/id?id=aitoawlhggg_yplkl7grwwpbbum-omtqud4rmna): Replying to [comment:3 Peter Stuge ]: > In [516fa7fdd9b55def83c124f223889c70b9e021ab/libssh2]: > {{{ > #!CommitTicketReference repository="libssh2" revision="516fa7fdd9b55def83c124f223889c70b9e021ab" > Don't save allocated packet size until it has actually been allocated > Thanks for the fix.
