INDI style drivers - URL BLOBS do not work and are unreliable in legacy mode. #357

Closed rumengb closed 4 years ago

rumengb commented 4 years ago

indigo server is started with: ./build/bin/indigo_server -vv -i build/drivers/indigo_ccd_simulator

  1. Legacy mode is unreliable:
rumen@sirius:~/indigo.git$ ./build/bin/indigo_prop_tool set -t 2 -b -l "DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE=0.1"
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.100000
save_blobs = 1, indigo_use_blob_urls = 0, item->blob.size = 0, item->blob.value = (nil), property->state = 2
DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE = <NO BLOB DATA>
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE = <BLOB => DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE.jpeg>
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
rumen@sirius:~/indigo.git$ ./build/bin/indigo_prop_tool set -t 2 -b -l "DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE=0.1"
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.100000
save_blobs = 1, indigo_use_blob_urls = 0, item->blob.size = 0, item->blob.value = (nil), property->state = 2
DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE = <NO BLOB DATA>
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
save_blobs = 1, indigo_use_blob_urls = 0, item->blob.size = 0, item->blob.value = 0x7f5e78001df0, property->state = 1
DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE = <NO BLOB DATA>
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
rumen@sirius:~/indigo.git$

Sometimes when exposure is done, CCD_IMAGE is OK but item->blob.size = 0, which basically means there is no data, but value is defined (see above).

However with dynamic drivers this never happens.

  1. URL BLOBs do not work at all: 
    rumen@sirius:~/indigo.git$ ./build/bin/indigo_prop_tool set -t 2 -b "DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE=0.1"
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.100000
save_blobs = 1, indigo_use_blob_urls = 1, item->blob.size = 0, item->blob.value = (nil), property->state = 2
DSLR Simulator @ indigo_ccd_simulator.CCD_IMAGE.IMAGE = <NO BLOB DATA>
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
01:04:04.164887 indigo_prop_tool: Can not retrieve data from /blob/0x561a86eb9ac0.jpeg
DSLR Simulator @ indigo_ccd_simulator.CCD_EXPOSURE.EXPOSURE = 0.000000
rumen@sirius:~/indigo.git$

    For INDI style drivers it is probably a good idea to switch to legacy mode BLOB transfer.

Some trace logs, i observe very strange behavior: The problem always appears when more than one client connected and one using legacy BLOB one using URL BLOB. In case of only one client behavior is consistent: with URL BLOB - never works, with legacy BLOB - always works. So I guess it is a race between clients...

 indigo_use_blob_urls = false;
