2018-08-24json: Clean up headersMarkus Armbruster1-1/+1
The JSON parser has three public headers, json-lexer.h, json-parser.h, json-streamer.h. They all contain stuff that is of no interest outside qobject/json-*.c. Collect the public interface in include/qapi/qmp/json-parser.h, and everything else in qobject/json-parser-int.h.

2018-08-24json: Pass lexical errors and limit violations to callbackMarkus Armbruster1-1/+2
The callback to consume JSON values takes QObject *json, Error *err. If both are null, the callback is supposed to make up an error by itself. This sucks. qjson.c's consume_json() neglects to do so, which makes qobject_from_json() null instead of failing. I consider that a bug. The culprit is json_message_process_token(): it passes two null pointers when it runs into a lexical error or a limit violation. Fix it to pass a proper Error object then. Update the callbacks: * monitor.c's handle_qmp_command(): the code to make up an error is now dead, drop it. * qga/main.c's process_event(): lumps the "both null" case together with the "not a JSON object" case. The former is now gone. The error message "Invalid JSON syntax" is misleading for the latter. Improve it to "Input must be a JSON object". * qobject/qjson.c's consume_json(): no update; check-qjson demonstrates qobject_from_json() now sets an error on lexical errors, but still doesn't on some other errors. * tests/libqtest.c's qmp_response(): the Error object is now reliable, so use it to improve the error message.

2018-08-24json: Redesign the callback to consume JSON valuesMarkus Armbruster1-9/+3
The classical way to structure parser and lexer is to have the client call the parser to get an abstract syntax tree, the parser call the lexer to get the next token, and the lexer call some function to get input characters. Another way to structure them would be to have the client feed characters to the lexer, the lexer feed tokens to the parser, and the parser feed abstract syntax trees to some callback provided by the client. This way is more easily integrated into an event loop that dispatches input characters as they arrive. Our JSON parser is kind of between the two. The lexer feeds tokens to a "streamer" instead of a real parser. The streamer accumulates tokens until it got the sequence of tokens that comprise a single JSON value (it counts curly braces and square brackets to decide). It feeds those token sequences to a callback provided by the client. The callback passes each token sequence to the parser, and gets back an abstract syntax tree. I figure it was done that way to make a straightforward recursive descent parser possible. "Get next token" becomes "pop the first token off the token sequence". Drawback: we need to store a complete token sequence. Each token eats 13 + input characters + malloc overhead bytes. Observations: 1. This is not the only way to use recursive descent. If we replaced "get next token" by a coroutine yield, we could do without a streamer. 2. The lexer reports errors by passing a JSON_ERROR token to the streamer. This communicates the offending input characters and their location, but no more. 3. The streamer reports errors by passing a null token sequence to the callback. The (already poor) lexical error information is thrown away. 4. Having the callback receive a token sequence duplicates the code to convert token sequence to abstract syntax tree in every callback. 5. Known bug: the streamer silently drops incomplete token sequences. This commit rectifies 4. by lifting the call of the parser from the callbacks into the streamer. Later commits will address 3. and 5. The lifting removes a bug from qjson.c's parse_json(): it passed a pointer to a non-null Error * in certain cases, as demonstrated by check-qjson.c. json_parser_parse() is now unused. It's a stupid wrapper around json_parser_parse_err(). Drop it, and rename json_parser_parse_err() to json_parser_parse().

json_parser_parse_err() may return something else than a QDict, in which case we loose the object. Let's keep track of the original object to avoid leaks. When an error occurs, "qdict" contains the response, but we still check the "execute" key there. Untangle a bit this code, by having a clear error path.

2018-07-03qga: removing bios_supports_modeDaniel Henrique Barboza1-40/+18
bios_support_mode verifies if the guest has support for a certain suspend mode but it doesn't inform back which suspend tool provides it. The caller, guest_suspend, executes all suspend strategies in order again. After adding systemd suspend support, bios_support_mode now will verify for support for systemd, then pmutils, then Linux sys state file. In a worst case scenario where both systemd and pmutils isn't supported but Linux sys state is: - bios_supports_mode will check for systemd, then pmutils, then Linux sys state. It will tell guest_suspend that there is support, but it will not tell who provides it; - guest_suspend will try to execute (and fail) systemd suspend, then pmutils suspend, to only then use the Linux sys suspend. The time spent executing systemd and pmutils suspend was wasted and could be avoided, but only bios_support_mode knew it but didn't inform it back. A quicker approach is to nuke bios_supports_mode and control whether we found support at all with a bool flag inside guest_suspend. guest_suspend will search for suspend support and execute it as soon as possible. If the a given suspend mechanism fails, continue to the next. If no suspend support is found, the "not supported" message is still being sent back to the user.

2018-07-03qga: systemd hibernate/suspend/hybrid-sleep supportDaniel Henrique Barboza1-0/+72
pmutils isn't being supported by newer OSes like Fedora 27 or Mint. This means that the only suspend option QGA offers for these guests are writing directly into the Linux sys state file. This also means that QGA also loses the ability to do hybrid suspend in those guests - this suspend mode is only available when using pmutils. Newer guests can use systemd facilities to do all the suspend types QGA supports. The mapping in comparison with pmutils is: - pm-hibernate -> systemctl hibernate - pm-suspend -> systemctl suspend - pm-suspend-hybrid -> systemctl hybrid-sleep To discover whether systemd supports these functions, we inspect the status of the services that implements them. With this patch, we can offer hybrid suspend again for newer guests that do not have pmutils support anymore.

2018-07-03qga: removing switch statements, adding run_process_childDaniel Henrique Barboza1-127/+88
This is a cleanup of the resulting code after detaching pmutils and Linux sys state file logic: - remove the SUSPEND_MODE_* macros and use an enumeration instead. At the same time, drop the switch statements at the start of each function and use the enumeration index to get the right binary/argument; - create a new function called run_process_child(). This function uses g_spawn_sync() to execute a shell command, returning the exit code. This is a common operation in the pmutils functions and will be used in the systemd implementation as well, so this function will avoid code repetition. There are more places inside commands-posix.c where this new run_process_child function can also be used, but one step at a time.

2018-07-03qga: bios_supports_mode: decoupling pm-utils and sys logicDaniel Henrique Barboza1-48/+68
In bios_supports_mode there is a verification to assert if the chosen suspend mode is supported by the pmutils tools and, if not, we see if the Linux sys state files supports it. This verification is done in the same function, one after the other, and it works for now. But, when adding a new suspend mechanism that will not necessarily follow the same return 0 or 1 logic of pmutils, this code will be hard to deal with. This patch decouple the two existing logics into their own functions, pmutils_supports_mode and linux_sys_state_supports_mode, which in turn are used inside bios_support_mode. The existing logic is kept but now it's easier to extend it. Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

2018-03-12Polish the version strings containing the package versionThomas Huth1-1/+1
Since commit 67a1de0d195a there is no space anymore between the version number and the parentheses when running configure with --with-pkgversion=foo : $ qemu-system-s390x --version QEMU emulator version 2.11.50(foo) But the space is included when building without that option when building from a git checkout: $ qemu-system-s390x --version QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty) The same confusion exists with the "query-version" QMP command. Let's fix this by introducing a proper QEMU_FULL_VERSION definition that includes the space and parentheses, while the QEMU_PKGVERSION should just cleanly contain the package version string itself. Note that this also changes the behavior of the "query-version" QMP command (the space and parentheses are not included there anymore), but that's supposed to be OK since the strings there are not meant to be parsed by other tools.

2017-12-21sockets: remove obsolete code that updated listen addressDaniel P. Berrange1-1/+1
When listening on unix/tcp sockets there was optional code that would update the original SocketAddress struct with the info about the actual address that was listened on. Since the conversion of everything to QIOChannelSocket, no remaining caller made use of this feature. It has been replaced with the ability to query the listen address after the fact using the function qio_channel_socket_get_local_address. This is a better model when the input address can result in listening on multiple distinct sockets. Signed-off-by: Daniel P.

When VM is in a heavy IO, if the command "guest-fsfreeze-freeze" is executed, VSS may timeout when trying to hold writes. Inside guest, Event ID 12298(VSS_ERROR_HOLD_WRITES_TIMEOUT) is logged in the Event Viewer. At that time, if we call AbortBackup, qga may hang forever. This patch will solve this issue.

Convert all the single line uses of fprintf(stderr, "warning:"..."\n"... to use warn_report() instead. This helps standardise on a single method of printing warnings to the user. All of the warnings were changed using this command: find ./* -type f -exec sed -i \ 's|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig' \ {} + Some of the lines were manually edited to reduce the line length to below 80 charecters. The #include lines were manually updated to allow the code to compile.

2017-08-08maint: Include bug-reporting info in --help outputEric Blake1-1/+1
These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.
