telebot's Issues

How use reply_markup

Hello, how using reply_markup?

Building under Debian Stretch for Raspberry Pi fails

I tried to build from source the testprogram echobot on my Raspberry Pi but building process fails under Debian Stretch. I remember, that it worked with Jessie but something changed now.
The mainreason for this that the packages "json" and "libcurl" are not available anymore with exact these names. But cmake checks in CMakeList.txt exactly for these packages and fails.
Any idea how to fix that?

Telebot does not provide API result to user

disable_notification is not working ?

It seems the notification sound is always there and the disable_notification is not present in the JSON debug printout ?
Or did I miss something ?
There seems to be a code treating it in the telebot-core_send-message() but then why it does not work ?

Bot crashes when two identic messages were sent in a row

I use example, provided in echobot.c.
When I try to send two identic messages ("abcd" or "test") in a row bot crashes with following error:

corrupted size vs. prev_size while consolidating

Can we add static library to CMakeList.txt file?

Possible deadlock in telebot-core.telebot_core_curl_perform()

The method sets core_h->busy = true, but never sets it back to false on error.

Native libcurl socks5 proxe support

It would be great to include into telebot native libCURL function to support SOCKS proxy.

Bot crashes at telebot_destroy(handle);

Hi,

I wrote simple bot that sends a message from command line. It sends message normally and crashes after call telebot_destroy(handle); .

telebot_handler_t handle;
if (telebot_create(&handle, token) != TELEBOT_ERROR_NONE) {
        printf("Telebot create failed\n");
        return -1;
    }
telebot_error_e ret;
if (!strcmp(argv[1],"--sendtext")) {
    		ret = telebot_send_message(handle, group_id, argv[2], "", false, false, 0, "");
    		if (ret != TELEBOT_ERROR_NONE) {
    			printf("Failed to send text message: %d \n", ret);
    		}
    } else {
    	printf("Unrecognized command\n");
    }
    telebot_destroy(handle);
}

Download image

I need to download the transmitted picture. I wrote the following small code:

	if (message->photo[1].file_size > 0) {
		char file_id[TELEBOT_FILE_ID_SIZE];
		strcpy(file_id,message->photo[1].file_id);
		ret = telebot_download_file(file_id, "photos/file_7.jpg");
		if (ret != TELEBOT_ERROR_NONE) {
			printf("Failed to download file: %d \n", ret);
		}
	}

But it does not work, it returns -1. In the process of debugging, it was revealed that a variable file_path was not obtained in the function of the telebot_error_e telebot_download_file(char *file_id, char *path).

ret = telebot_parser_get_file_path(obj, &file_path);
json_object_put(obj);

if (file_path == NULL) {
	printf("if (file_path == NULL) {\n");
	return TELEBOT_ERROR_OPERATION_FAILED;
}

Specifically, the problem in this function call:

telebot_error_e telebot_parser_get_file_path(struct json_object *obj,
char **path) {

if (json_object_object_get_ex (obj, "file_path", &file_path)) {
	*path = strdup(json_object_get_string(file_path));
	json_object_put (file_path);
}
else {
	*path = NULL;
	return TELEBOT_ERROR_OPERATION_FAILED;
}

}

This function returns TELEBOT_ERROR_OPERATION_FAILED. The system displays the following debugging messages:

What am I doing wrong?

stdbool.h header is not added by default

Can we get rid of this dependency?
error: unknown type name ‘bool’

How to use buttons?

Can somebody show examples how to use keyboard buttons & inline buttons?

can't get caption

I can't get the caption even with using message.caption

telebot uses 32 bit int for chat id which needs up to 56 bits

The example echobot fails to send messages to some group chats (and maybe some private chats too). In general it is safe to use 32 bit signed integer for all integer types as notet in the telegram bot api description. However there is one exception, that is the chat ids, which may use up to 56 bits (https://core.telegram.org/bots/api#chat). The telebot library also uses 32 bit signed integer (int) to store these chat ids. Apperently thats the cause for those random failure to send data to a chat.

first steps using echobot

HI,

I´m having troubles to test echobot example.

I have a bot called SaborDelivery (@luisgama_bot ) .

this bot is running ok between my telegram app ( under debian 8 ) and my cell phone, but when I´m try to use echobot:

Welcome to Echobot
Token: 268963290:AAHprXUwmtHf7Kt1mlR19riL74WiYBdPFRs
[ERROR][telebot_core_curl_perform:84]Failed to curl_easy_perform
Error: Couldn't connect to server (7)
Failed to get bot information

Am I doing anything wrong?

Thanks

User editing already send message will result in crash.

If the user presses the arrow up key in Telegram to access his last written message and then edits that message the echobot will crash with Segmentation Fault in line 66.
message.from, message.text and message.chat are all NULL

Telebot crashes if user send less then 3 characters.

I have played around with echobot.c and found that it crashes if I send 2 letters. No problems if I send 3 or more letters. Got errors:
[DEBUG][telebot_core_curl_perform:142]Response: {"ok":true,"result":[{"update_id":345541365, "message":{"message_id":86,"from":{"id":337925211,"is_bot":false,"first_name":"Loosing","last_name":"Control","username":"Cartoonboy","language_code":"en"},"chat":{"id":337925211,"first_name":"Loosing","last_name":"Control","username":"Cartoonboy","type":"private"},"date":1594114626,"text":"du"}}]} corrupted size vs. prev_size Aborted (core dumped)
or

[DEBUG][telebot_core_curl_perform:142]Response: {"ok":true,"result":[{"update_id":345541357, "message":{"message_id":76,"from":{"id":337925211,"is_bot":false,"first_name":"Loosing","last_name":"Control","username":"Cartoonboy","language_code":"en"},"chat":{"id":337925211,"first_name":"Loosing","last_name":"Control","username":"Cartoonboy","type":"private"},"date":1594113760,"text":"ll"}}]} malloc(): invalid next size (unsorted) Aborted (core dumped)

The only change I made in echobot.c was function "telebot_send_dice(....)" which can be called by "/dice".
So, if I send bot "du" or other two characters it crashes and to make bot work properly again i need to call "/dice" command and start bot again, otherwise it crashes receiving last command "du".

And I'm lack of inline keyboard))))) I saw in doc's that it is in TODO mood, and I hope you will do it in recent future. Yep, I am that one strange guy who wants to write bot using C in 2020)))))

P.S. it also crashes if user sends emoji or sticker

docs?

so i want to make a tg bot with this lib but i dont find any biginer frendly spreedsheet or exemple i dont understand the lib

Error on file send

Hello, I get an error, when I try to send a file. There is no problem with text messages.

The code:

...
int someid = 0;
char str[4096];

snprintf(str, SIZE_OF_ARRAY(str), "/path/to/a/document.extension");
ret = telebot_send_document(handle, someid, str, true, "", "aaa", "", false,0,"");

if (ret != TELEBOT_ERROR_NONE) {
    printf("Failed to send message: %d \n", ret);
}
...

The error message:

[ERROR][telebot_core_curl_perform:129]Failed to curl_easy_perform
Error: Failed to open/read local data from file/application (26)
Failed to send message: -1 

How to compile on Windows?

I would like to use your library, but could not figure out how to compile it on Windows. Can you help me out?

I get following error:
C:\Program Files (x86)\CodeBlocks\MinGW\include\pthread.h|196|error: unknown type name 'uintptr_t'

Failed to send file as document, server response is 400

ret = telebot_send_document(handle, sstgbconf.user_id, sstgbconf.docfile, true, false, 0, NULL); if (ret != TELEBOT_ERROR_NONE) { printf("Failed to send document: %d \n", ret); }

The result is:

[ERROR][telebot_core_curl_perform:95]Wrong HTTP response received, response: 400
Failed to send document: -1

Possibly changes in Telegram API ?

make install would be nice

so the API canbe installed and used in an universal way from other applications.

Failed to curl_easy_perform

the library output is giving me
[ERROR][telebot_core_curl_perform:92]Failed to curl_easy_perform Error: URL using bad/illegal format or missing URL (3)

echobot leaks memory

I modified the echobot loop so that it will break after the 5th iteration and checked with valgrind for memory leaks. Note that I was sending the bot no messages during this test.

More Extensive Documentation?

So far for me the header files are sufficient, but I was wondering whether it would be worth creating a Wiki page to get new users started? I was also wondering whether the ability to display a couple of clickable options to the user is implemented (obviously this exposes how new I am to the telegram bot api in general).

Thank you very much for this effort!
The API framework appears pretty robust and stable so far

When I try to build a static binary for echobot, linker fails with a lot of "undefined reference to symbol (libcurl, libjsonc functions)" errors.

Crash on messages forwarded from chats

Telebot crashes when freeing updates object if one of the messages was a forward from a chat.

I traced the problem to line 488 in telebot-parser.c, which seems to be a mistake when copy pasting similar code.

telebot/src/telebot-parser.c

Lines 485 to 494 in c74d78d

	struct json_object *forward_from_chat = NULL;
	if (json_object_object_get_ex(obj, "forward_from_chat", &forward_from_chat))
	{
	msg->forward_from = malloc(sizeof(telebot_user_t));
	if (telebot_parser_get_chat(forward_from_chat, msg->forward_from_chat) != TELEBOT_ERROR_NONE)
	{
	ERR("Failed to get <forward from> from message object");
	TELEBOT_SAFE_FREE(msg->forward_from_chat);
	}
	}

It ought to be msg->forward_from_chat = malloc(sizeof(telebot_chat_t));.

This causes a bug in which msg->forward_from is overwritten with a pointer to uninitialized memory. This causes issues during freeing, as telebot_put_user sees non-null pointers and tries to free them. This causes memory corruption and an eventual crash.

too frequent fatal errors

my bot stops working many times. sometimes even stops after a minute after starting.
most errors are:
free(): invalid pointer (I don't use free() in my code)
double free or corruption (out)
unable to get forwarded from
