read_chan() error "AttributeError: 'Siteclient' object has no attribute 'raw_data_size'"

[cenkoloji]

Hello folks, It seems since I started using "master" branch instead of pip package, I have an issue with read_chan method (It's for Real-time Thomson, that use SOD, non-demuxed)

In [1]: import acq400_hapi

In [2]: uut = acq400_hapi.Acq2106("rtthom001", monitor=False)

In [3]: uut.read_chan(0, -1)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[3], line 1
----> 1 uut.read_chan(0, -1)

File /usr/local/pyenvs/tcvpy39env/from-source/acq400_hapi/acq400_hapi/acq400.py:636, in Acq400.read_chan(self, chan, nsam, data_size)
    633     data_size = 4 if self.s0.data32 == '1' else 2
    635 if chan == 0:
--> 636     nsam = int(self.s0.raw_data_size) // data_size
    637 if chan != 0 and nsam == 0:
    638     nsam = self.pre_samples()+self.post_samples()

File /usr/local/pyenvs/tcvpy39env/from-source/acq400_hapi/acq400_hapi/netclient.py:214, in Siteclient.__getattr__(self, name)
    212 else:
    213         msg = "'{0}' object has no attribute '{1}'"
--> 214         raise AttributeError(msg.format(type(self).__name__, name))

AttributeError: 'Siteclient' object has no attribute 'raw_data_size'

Working version is the latest installed by pip: acq400_hapi-2.9.4

Hello Cenk We're sorry to see that the upgrade has broken your code. We try to improve this code all the time, but sometimes it's not possible to maintain back compatibility. The change in HAPI is from: e2a5c50 acq400_hapi/acq400.py (Peter Milne 2023-03-11 14:59:08 +0000 636) nsam = int(self.s0.raw_data_size) // data_size raw_data_size is actually part of the ESW: acq2106_130> ls -l /etc/acq400/0/raw_data_size lrwxrwxrwx 1 root root 29 Oct 13 15:14 /etc/acq400/0/raw_data_size -> /usr/local/CARE/get_data_size That file has been in the ESW (Embedded SoftWare) since: (base) ***@***.***:~/PROJECTS/ACQ400/ACQ400DRV$ git log CARE/get_data_size commit d71e485573d69cc77b45dfef9a093f5d2001677e Author: Peter Milne ***@***.***> Date: Fri Aug 19 14:47:24 2022 +0100 raw_data_size knob in site0, ch_data_size in all adc sites That leaves you with the choice either to update firmware or to revert the HAPI version. If the old HAPI version was already working for you in this case, that would probably be the quicker option. Best regards Peter

Or a workaround would be to install the change as a temporary custom package eg 36-raw_data_size_patch-YYYMMMDDD.tgz From this git-patch (base) ***@***.***:~/PROJECTS/ACQ400/ACQ400DRV$ git diff d71e485573d69cc77b45dfef9a093f5d2001677e^..d71e485573d69cc77b45dfef9a093f5d2001677e diff --git a/CARE/get_data_size b/CARE/get_data_size new file mode 100755 index 0000000..75a673e --- /dev/null +++ b/CARE/get_data_size @@ -0,0 +1,12 @@ +#!/bin/sh + +SITE=${SITE:-0} + +case $SITE in +0) + FN=/dev/acq400/data/raw/0;; +*) + FN=/dev/acq400/data/$SITE/01;; +esac + +stat -c%s $FN diff --git a/init/acq420.init b/init/acq420.init index 576056a..8a323c5 100755 --- a/init/acq420.init +++ b/init/acq420.init @@ -473,6 +473,9 @@ build_knobs_device() { *) CLKDIV=200;; esac + if [ -e ${ek}/is_adc ] && [ "$(cat ${ek}/is_adc)" != "0" ];then + ln -s /usr/local/CARE/get_data_size ${ek}/ch_data_size + fi if [ "$CLKDIV" != "noset" ] && [ -e $dk/clkdiv ]; then set.sys $dk/clkdiv $CLKDIV rb=$(get.sys $dk/clkdiv) @@ -566,6 +569,7 @@ build_site0() { for knob in NCHAN data32 shot shot_complete; do echo 0 > /etc/acq400/0/$knob done + ln -s /usr/local/CARE/get_data_size ${ek}/raw_data_size echo "+++ build_site0 model $MODEL" case $MODEL in

Thanks for quick response as usual,
I'll remain with old acq400_hapi for now and try to upgrade the thomson box to a recent release, so I don't have many patches...
