1.42-1.42.1: hledger-web hangs when saving large journal files

[Simaex]

After upgrading to the latest hledger version, hledger 1.42.1, linux-x86_64 hledger-web 1.42.1, linux-x86_64
I have experienced a problem editing even moderate-sized journals, much smaller than we used to edit before.
Depending on the data, hledger-web's built-in editing failed for journals from 51 to 100k
This was never an issue before, even for 300k-sized journals.

I prepared a set of sample journals to reproduce the issue.

Which hledger version was faster for you ?

[simonmichael]

I should say: which hledger-web version was working better for you ?

[simonmichael]

Never mind! I can reproduce: hledger-web-1.41 --allow=edit saves changes to a large file normally, whereas 1.42.1 appears to hang when you click Save.

It seems to be caused by #2319.

Fixed in master; I'll release as 1.42.2 soon.

Nasty, thanks for reporting!

[simonmichael]

Released.
