dump_bin DumpDataUpdate mode append data error

[hbhuyt]

🐛 Bug Description

At first, I used Dump_bin's DumpDataAll mode to import data it worked fine. Part of the imported data is as follows df[df['instrument']=='SH600306'] Out[35]: instrument datetime $volume $factor $close 41691 SH600306 2024-04-23 1022018.0 0.281253 0.686257 41692 SH600306 2024-04-24 1372334.0 0.281253 0.652507 41693 SH600306 2024-04-25 951008.0 0.281253 0.618756 41694 SH600306 2024-04-26 1968818.0 0.281253 0.587818 41695 SH600306 2024-04-29 1532764.0 0.281253 0.559693

But when I append new data with DumpDataUpdate, there is an error. The original data is as follows dfraw.loc[(dfraw['date']>'2024-04-29'),['instrument','date','close']] Out[54]: instrument date close 4356 SH600306 2024-05-29 0.098438 4357 SH600306 2024-05-30 0.092813 4358 SH600306 2024-05-31 0.101251 4359 SH600306 2024-06-03 0.092813 4360 SH600306 2024-06-04 0.095626 4361 SH600306 2024-06-05 0.092813 4362 SH600306 2024-06-06 0.092813 4363 SH600306 2024-06-07 0.095626 4364 SH600306 2024-06-11 0.090001 4365 SH600306 2024-06-12 0.090001 4366 SH600306 2024-06-13 0.087188 4367 SH600306 2024-06-14 0.081563

Some of the imported data is shown below

I am hoping to debug dump_bin.py to find the problem. I ran it to here，the following code may be problem.

    def _data_to_bin(self, df: pd.DataFrame, calendar_list: List[pd.Timestamp], features_dir: Path):
        if df.empty:
            logger.warning(f"{features_dir.name} data is None or empty")
            return
        if not calendar_list:
            logger.warning("calendar_list is empty")
            return
        # align index
        _df = self.data_merge_calendar(df, calendar_list)
        if _df.empty:
            logger.warning(f"{features_dir.name} data is not in calendars")
            return

When align index, calendar_list does not contain dates such as 2024-05-06, but SH600306 data is empty in these days.
