Dear MIDAS experts,
I'm running into a minor but annoying issue with the subdirectory name ordering by the ODB browser.

04 Jun 2025, Mark Grimes, Bug Report, Memory leak in mhttpd binary RPC code
|
Hi,
During an evening of running we noticed that memory usage of mhttpd grew to close to 100Gb. We think we've traced this to the following issue when making
RPC calls.

Hi,
We applied an intermediate fix for this locally and it seems to have fixed our issue. The attached plot shows the percentage memory use
on our machine with 128 Gb memory, as a rough proxy for mhttpd memory use. After applying our fix mhttpd seems to be happy using ~7% of the memory |

10 Jun 2025, Nik Berger, Bug Report, History variables with leading spaces
|
By accident we had history variables with leading spaces. The history schema check then decides that this is a new variable (the leading space is not read
from the history file) and starts a new file. We found this because the run start became slow due to the many, many history files created. It would be
nice to just get an error if one has a malformed variable name like this.

I confirm that MJSON_ARRAYBUFFER does not work correctly for zero-size buffers,
buffer is leaked in the destructor and copied as NULL in MJsonNode::Copy().

Many thanks for the fix. We've applied and see better memory performance. We still have to kill and restart
mhttpd after a few days however. I think the official fix is missing this part:

I added now code to the logger so it properly complains if there would be a leading space in a variable name.

Since this memory leak is quite obvious, I pushed the fix to develop.

04 Jul 2025, Mark Grimes, Bug Report, Memory leaks in mhttpd
|
Something changed in our system and we started seeing memory leaks in mhttpd again. I guess someone
updated some front end or custom page code that interacted with mhttpd differently.
I found a few memory leaks in some (presumably) rarely seen corner cases and we now see steady

I commited a fix to mhttpd logic that decides which messages should be shown in
"red" colour- before, any message with square brackets and colons would be
highlighted in red. Now only messages matching the pattern [...:...] are

We stumbled upon and fixed a "double free" bug in src/ybos.c causing crashes in
lazylogger writing .mid files in the FORMAT_MIDAS format (why does it use
ybos.c? Pierre says- for generic file i/o). Why this code had ever worked before

I fixed some minor bit rot in the example experiment: a few minor Makefile

also added startup and shutdown scripts. These will be documented as we work
