* Fix upload losing synchronization if root not mounted (RHBZ#576879).Richard Jones2010-04-171-12/+0
| | | | | | | | | | | | Modify the generator so that it can correctly handle early cancellation for Pathname|Device|.. parameters. This fixes the upload command, but consequently we need to fix the parameters for tar_in and t?z_in commands. This should also mean that 'win:' can now be used as the second argument of tar_in and t?z_in commands in guestfish, whereas previously this wouldn't have worked. Adds a regression test for the original problem.
* New API calls to upload/download txz files (RHBZ#580556).Richard Jones2010-04-081-6/+34

* Code cleanups related to RHBZ#580246.Richard Jones2010-04-081-17/+16
| | | | | | | | | | | | | | This includes various code cleanups: (a) A regression test for RHBZ#580246. (b) Use write instead of fwrite to write out the tar file. This is just because the error handling of write seems to be better specified and easier to use. (c) Use size_t instead of int for length. (d) Clearer debug messages when in verbose mode.
* Fix tar-in command hangs when running out of disk space (RHBZ#580246).Richard Jones2010-04-081-2/+4
| | | | | | | | | | | | | | | | | | | | The problem was this sequence of events: (1) File transfer goes through OK. (2) pclose returns failure (because 'tar' subprocess failed) (3) We try to cancel the transfer by calling cancel_receive. Step (3) fails because the transfer (as far as the library is concerned) has succeeded, so causing a hang. The more fundamental reason why we see steps (1) and (2) is that 'tar' does NOT fail immediately if there is a write error. Instead it continues reading and discarding the input until the end of the input before giving "Error exit delayed from previous errors". IMHO this is a bug with tar, since an ENOSPC write error should be fatal for tar.
* daemon: Don't need to prefix error messages with the command name.Richard Jones2010-02-121-2/+2
| | | | | | | | | | | | | | | | | | | | The RPC stubs already prefix the command name to error messages. The daemon doesn't have to do this. As a (small) benefit this also makes the daemon slightly smaller. Code in the daemon such as: if (argv[0] == NULL) { reply_with_error ("passed an empty list"); return NULL; } now results in error messages like this: ><fs> command "" libguestfs: error: command: passed an empty list (whereas previously you would have seen ..command: command:..)
* daemon: diagnose socket write failureJim Meyering2009-08-201-2/+6
| | | | | | | | | * daemon/proto.c (send_chunk): Don't ignore socket-write error. * daemon/proto.c (send_file_end): Return "int", not void, so we can propagate send_chunk failure to caller. * daemon/daemon.h (send_file_end): Update prototype. * daemon/tar.c (do_tar_out, do_tgz_out): Update uses of send_file_end. * daemon/upload.c (do_download): Likewise.
* generator.ml: use new "Pathname" designationJim Meyering2009-08-131-10/+4
| | | | | | | | | | Nearly every file-related function in daemons/*.c is affected: Remove this pair of statements from each affected do_* function: - NEED_ROOT (return -1); - ABS_PATH (dir, return -1); and change the type of the corresponding parameter to "const char *". * src/generator.ml: Emit NEED_ROOT just once, even when there are two or more Pathname args.
* update all NEED_ROOT usesJim Meyering2009-08-131-2/+2
| | | | | | run this command: git grep -l -w NEED_ROOT|xargs perl -pi -e \ 's/(NEED_ROOT) \((.*?)\)/$1 (return $2)/'
* update all uses of ABS_PATHJim Meyering2009-08-131-2/+2
| | | | | | run this command: git grep -l -w ABS_PATH|xargs perl -pi -e \ 's/(?:ABS_PATH)( \(.*?,) (.*?)\)/ABS_PATH$1 return $2)/'
* Replace shell_quote function with %Q and %R printf specifiers.Richard Jones2009-07-281-36/+24
| | | | | | | %Q => simple shell quoted string %R => path will be prefixed by /sysroot eg. snprintf (cmd, sizeof cmd, "cat %R", path); system (cmd);
* Make /sysroot path configurable.Richard Jones2009-07-181-8/+12
| | | | | | | | | Currently /sysroot is hard-coded throughout the daemon code. This patch turns the path into a variable so that we can change it in future, for example to allow standalone mode to be implemented. This patch was tested by running all the C API tests successfully.
* remove trailing blanksJim Meyering2009-07-031-1/+1

* All instances of 'pclose' now check for return value != 0.Richard W.M. Jones2009-07-011-4/+4
| | | | | | We are generally interested that the subcommand ran without error, ie. had exit status of 0. 'pclose' returns the exit status, so we now check that pclose (fp) != 0.
* In the daemon, change all const char * parameters to char *.Richard Jones2009-06-101-4/+4
