Detailed description

When I first run in terminal and enter the password I get this error Password: error: failed to format output: consume [avatar]: can't read attachment of length 0

However, if I run it again and just hit return for the password without entering it, it creates a file that is empty. Below is what I see in terminal

I also tried it on two other computers with the same results. An iMac, and a PC

ghost commented 5 years ago

Same issue here on Windows (amd64), the XML file is almost empty : the program behaves as if all worked well, but the XML only contains : "<"?xml version='1.0' encoding='UTF-8' standalone='yes' ?">" "<"?xml-stylesheet type="text/xsl" href="sms.xsl" ?">" "<"smses count="0"></smses">" (without the quotes at the begining and end of each line) which makes it around 1kb. The CSV export seems to work fine though (but I don't have any option to restore it as an SMS database for the moment so kinda useless) and the extract functions as well.

Hi all, I'm having the same issue on Windows (amd64). The XML file just contains the wrapper, with SMS count at 0.

Have the binary file and the backup file in the same directory, and entered:

signal-back_windows_amd64.exe format -f XML -o backup.xml signal-2019-04-29-19-51-27.backup

Feel like I must be missing something simple...help?

edit: oh, found this previous issue (https://github.com/xeals/signal-back/pull/43), but having trouble figuring out how to adjust what i'm doing? should i be finding a different version of the binary or something?

more edits: ok, realized i didn't specify which release i was using. originally was using v0.1.6. After reading the pull request referenced above, tried the most recent pre-release (v0.1.7-alpha2), but then when i ran the command, when prompted for password it didn't seem to accept any text i entered, whether the password itself or trying to pass the file with -P pass.txt. what i mean by "didn't seem to accept", i mean the cursor doesn't move all when i try to respond to the password prompt.

returns error:

"error: failed to format output: consume [avatar]: can't read attachment of length 0"

which i assume means it couldn't parse the password, because of course it didn't receive anything from me.

tried going back one and using v.0.1.7-alpha1, same problem. any thoughts?

even more edits! Found in this issue (https://github.com/xeals/signal-back/issues/47) that the poster had used the -P pass.txt in the initial command, and tried that with v0.1.6 and, voila!

At this point, I'm waiting for help from the developer. We shall wait ;)

Version 1.7.2 32-bit fixes the one byte XML output issue for me on Windows 7.

Command: signal-back_windows_386.exe format -f XML -o backup.xml -P pass.txt signal.backup

Billy4130 commented 5 years ago

I've ran this from version 1.06 and also 1.7.2 both now and still get a zero byte xml file...

Running Windows 10 x64.

Are you guys trying to run the x386 binary?

I downloaded the amd64 version of 1.7.2 and ran it, then manually entered my pass code (no text file) and it worked. The password prompt is shielded so you wont get cursor feedback or see what you're typing but it does accept input.

This solved it for me and now I have a full size xml file, and it ran without errors too :-)

Seeing similar issue in Windows 10 x64. Tried the precompiled binary, and even compiling the latest few commits, with or without the password file/prompt. Consistently getting the same error:

error: failed to format output: consume [avatar]: can't read attachment of length 0

I guess this project has been abandoned?

I'm getting the same issue too, I'm trying everything. Tried two different backup files, double-checked the password, tried entering the password manually and with the password file, tried all 3 different output types (raw, XML, CSV), and I always get the

error: failed to format output: consume [avatar]: can't read attachment of length 0

error. It's a real problem, I need this output for legal issues. A shame this has been abandoned. I've tried this using build binaries on MacOS and Centos, I've tried using the prebuilt binary on Windows, same issue.

I'm guessing this utility is simply no longer compatible with new versions of Signal (I'm trying this in May of 2020).
