Hi again @kdunwoody @CoRfr .
I think I’ve stumbled upon another IDL
file issue, but this time relating to
file fd IN?
I migrated to Legato 17.09.0 from 16.10.3 about a day ago and manually implemented the ifgen fix (issue 19) for
file fd OUT as per the previous posts.

I built my own .sdef using
mksys after running
bin/legs in the legato dir downloaded from https://github.com/legatoproject/legato-af/tree/17.09.0.
I did try building the system in Dev Studio 5.3 after adding 17.09.0 as a custom package but the system crashed after applying the update (possibly a toolchain related problem?).
Anyway, the test I was running basically consists of performing these operations every 5 minutes:
- Connect to a webserver (HTTPS using libcurl) and sync system time
- Read sensor data from an external serial device.
- Store data on SD card
- Connect to FTP server and upload file (with libcurl)
My test app ran fine for roughly 20 hours until I observed some odd behavior. It’s running
Oct 25 06:26:26 | myService/framework T=main | my_web_client.c my_web_FtpUploadFile() 958 | Sending message to server and waiting for response : 23 bytes sent
Oct 25 06:26:26 | myService/framework T=main | LE_FILENAME unixSocket_SendMsg() 441 | Sending fd 19.
Oct 25 06:26:26 | myWeb/framework T=main | LE_FILENAME unixSocket_ReceiveMsg() 669 | Ancillary data was discarded because it couldn't fit in our buffer
Oct 25 06:26:26 | myWeb/myWebServiceComponent T=main | myWebService.c FtpUploadFile() 1026 | Couldn't open file: Bad file descriptor
I noted several FTP Timeouts logged for a couple of hours leading up to this which would have resulted in the file size growing by ~49 bytes each time. Could this be a file size restriction imposed in a later version of Legato?
Note that I’ve set
maxFileBytes: 8192K and have been able to upload a file several MB in size without issue before.
This is what the log usually looks like when it’s working.
Oct 25 23:21:29 | myService/framework T=main | my_web_client.c my_web_FtpUploadFile() 958 | Sending message to server and waiting for response : 23 bytes sent
Oct 25 23:21:29 | myService/framework T=main | LE_FILENAME unixSocket_SendMsg() 441 | Sending fd 19.
Oct 25 23:21:29 | myWeb/framework T=main | LE_FILENAME ExtractFileDescriptor() 34 | Received fd (209).
Oct 25 23:21:29 | myWeb/myWebServiceComponent T=main | myWebService.c FtpUploadFile() 1030 | Local file size: 49 bytes.
The function signature looks like this:
le_result_t my_web_FtpUploadFile(const char* filename, int fd);
DEFINE MAX_STR_LEN = 512;
FUNCTION le_result_t FtpUploadFile
string filename [MAX_STR_LEN] IN,
file fd IN
Additionaly, issues with the HTTPS queries started to fail and logged this on libcurl’s verbose output:
error reading ca cert file /etc/ssl/certs/ca-certificates.crt (Error while reading file.)
And the error message was:
curl_easy_perform() failed: Problem with the SSL CA cert (path? access rights?)
I’m unsure if these are related to each other but they appear to be caused by file reading issues. In any case, they never appeared in 16.10.3 after months of running continuously and uninterrupted.
Nothing has changed in the .cdef’s or .adef’s. They include all the files and libs needed as per the
httpGet sample code. Do I need to add anything else or explicitely give access to certain dirs since moving from Legato 16.10.3?
Note that restarting the app resolves both issues (temporarily) until it falls over again some 10’s of hours later.
Any help would be much appreciated. Thanks.
