Summary: curlftpfs hangs after reading files with no write permission

Initial Comment:
i have already reported this problem to the curlftpfs bugzilla.

http://sourceforge.net/tracker/index.php?func=detail&aid=1809225&group_id=160565&atid=816357

i'm not sure if this is really a libcurl problem, but there is a suspicion that libcurl doesn't move into a working state after reading a file failed (because no read permissions for the ftp user).

if there is a possibility to reproduce this bug without curlftpfs please tell me and i will try (perhaps a peace of demo code, which also uses curl_multi).

thanks, but i think that's not a file-not-found problem, but a
permission-denied problem.

> RETR messages.4
* FTP 0x80658d0 state change from RETR_SIZE to RETR
< 550 messages.4: Permission denied
* RETR response: 550
...
> RETR messages.3
* FTP 0x80658d0 state change from RETR_SIZE to RETR
< 550 messages.3: Permission denied
* RETR response: 550
...

have a look at curlftplog.txt, which i attached to the curlftpfs bug
report.

after trying to read messages.4 and messages.3 (which both have no read
permissions), reading messages.2 (for which i have read permissions)
hangs:

...
> RETR messages.2
* FTP 0x80658d0 state change from RETR_SIZE to RETR
< 150 Opening BINARY mode data connection for messages.2 (84257 bytes)
* Maxdownload = -1
* Getting file with size: 84257
* FTP 0x80658d0 state change from RETR to STOP
* DO-MORE phase ends with 0
* STATE: DO_MORE => DO_DONE handle 0x808e3e4; (connection #0)

* Conn 0 recv pipe 1 inuse 0 athead 1
* STATE: WAITPERFORM => PERFORM handle 0x808e3e4; (connection #0)

(hangs)

I've created test case 546 that tests a file-not-found FTP transfer
followed by a found one using the multi interface, and it passes fine.

sorry - the title of this bug report should be:
curlftpfs hangs after reading files with no READ permission
